' anmmcm'ron.

. To all whom it may concern: v p Be itknown that we, WrLLIAM C. Maro T and Joux HoULEnAx, citizens of the United States, residing at El Paso, in the county of El Paso and State of Texas, have invented a new and useful Annunciator, of which the xfollowing is a specification. This invention has reference to improvements in annunciators designed more particularly for the phonographic announcing of stations and other routine information on cars or trains of any character. .The invention is designed for use 'in con-- nection with a com lete traction system which we have devise and since in this systern the operations are mostly automatic in character, it becomes necessary that all an nouncements, such as the names of stations, calls to meals, and other matters which are usually called out by a train otlicial shall be 1 made by phonographic means and shall be vso timed and arranged that each passenger shall surely hear the announcement.

T In the system in which {zhese annunciators are designed to be used it is impracticable to use spring motors for the purpose of driving the instruments and so connections are made with. the air system of a tram whereby the air 7 pressure, which, in accordance with our general system is constantly maintained, is employed to drive the various parts of the annunciator and to actuate the several parts which are'necessa for the fully automatic evices comprised in the present invention. 1- The present. 'nvention comprises a soundreproducing means utilizing a sound record, preferabl of the cylindrical type although tmodifications the same instrucase the sound records should" e of material 1' capable of numerous reproductions, but as 1 1 such record materials are found on the mar- ,45 ket and sound record tablets have been made .ifrom such materials, it is unnecessary td con- 1 sider herein'the character of the record.

The invention comprises a means under the l icontrol of the air pressure in the system used '5 0' for braking and other urposes, for settm 'up rotary motion of t e cylindrical sour.

-' record and feeding the sound-box across the record tosuch extent and at such times as {may be necessarv to cause the desired 8117' sfi nouncements to e made.

Specification of Letters Patent. Application filed May 22 1907. Serial No. 375.090.

' verse order, for the return trip w Patented Feb. 18, 1908;

- In order that the announcements may be made at the proper time, the motor for'the phonographic annunciator may be under the control of a release mechanism which maybe operated from fixed points along the roadway; so and provision is also made for conducting the reproduced sounds to points adjacent to the seats occupied by the passengers on the car so that each passenger may receive an indi vidual announcement in spoken words. 5 The invention will be best understood by a consideration of the practical embodimentv thereof, and, therefore, we will proceed to describe such practical embodiment in connection with the accompanying drawings forming part of this specification, in which drawings,

Figure 1 is a plan view, with parts in section, of aphonographic reproduccr of the cylindrical record tablet type arranged to operate automatically as many times as desired; Fig. 2 is a skeleton view of the driving mechanism for the structure shown in Fig. 1; Fig. 3 is a cross section of the cylinder for receiving air for driving the mechanism; 4 so is an elevation, artly in section f the mechanism employs for returning the sound-box to its initial position after havi traversed the length of a record cylinder; F1gs. '5 to 1],, both inclusive, are detail views of various g5 parts'of the mechanism; Fig. 12 is a sectional view, partly in diagram, of a means for silencing the .IQPIOdUCilOIl without throwing the mechanism out of action; Fig. 13 is 'a plan view of a portion of the same; and Fig. 14 is a detail view of a portion of the structure shown in 1 2.

Referring to the drawings, and more particularly to Fig. 1, there is shown a cylindrical record tablet I of the ordinary type upon which there are presumed to be such announcements as desired, say the announce-- merits of the stations being a proached and their character, and such ot er announce-- ments as it may be desirable to make.

Since our system contemplates the eiimi-" nation, to a great extent, of train -attendants, it becomes, of course, imperative that the announcements be made at the proper times and in pro er sequence and that a single rec- 05 0rd shoul contain all the announcements that are to be made during a trip, and, in reiere it is not practicable to change the'record at tne end of a run. For this reason the record 1 wi1l,-110

mechanism 6 whereby the hearing may be removed from the shaft sufficiently to allow the removal and replacing of the record 1 upon the mandrel 2. Since this gate may be o the usual type, it is unnecessary to describe it in detail.

It will be seen that it is necessary that the record tablet should always be placed upon the mandrel in'the same relative position thereto, and for this urpose there is secured to the smaller end the mandrel a slotted plate 7 by means of a thumb-screw 8, or, if desired, an ordinary screw, passing through the slot in the plate 7. One end of this plate 7 is ointed, as indicated at 9, and enters a pote formed in the end of the record tab- There is provided a sound-box 10 which may be of the ordinary reproducer soundbox type, and, therefore. needs no description here, but the manner of supportin this sand-box and of operating the same to ring it into proper relation with the record will ap )ear further on.

etween the mandrel and the bearing 5 the shaft 3 is provided with a continuous screw -thread 11, after the manner of the ordinary reproducing machine using cylindrical records, and adapted to this screwthread there is a half-nut 12, best shown in Fig. 8. This'half-nut 12 is at the end of an arm 13 terminating in two parallel fingers 14 appropriately spaced apart. The half-nut 12 is composed of a suitably shaped block .seated between the fingers 14 and provided with lugs 15 projecting into slots 16 formed in the free ends of the fingers 14 so that this half-nut may move longitudinally between the' fingers 14' but can have no other movement with relation thereto. It will be understood, of course, that though the lugs 15 are shown about midway of the half-nut- 12 they may be otherwise located, and other means for guiding the half-nut 12-between the fingers 14 may be provided. Extending through the arm 13 between the fingers 14- is a screw 17 having an elongated, smooth shank and a short screw extension 18,- which latter enters a suitable nut formed in the body of the half-nut 12 to such an extent that the shoulder formed by the junction of the shank 1.7 with the screw extension 18 5 abuts against the rear of the half-nut 12.

The bearmg may be provided with the usual gate Where it surrounds the shaft '21.

Surrounding the shank of the screw 17 between the half-nut 12 and the-inner face/of the arm 13 there is a helical spring 19 tending to maintain the halfnut in its outermost position but yielding when the nut engages with the screw-threads 11 on the shaft 3; so that the nut may be firmly seated on the screw-threads without danger of being displaced therefrom hy the shocks incident to the movementof the ear.

Mdunted upon the end of the shat t 3 near the bearing 5 is a gear pinion 20 by means of which a rotative movement is imparted to the shaft- 3 in a manner to be described with relation to Fig. 2 and to which reference will be made further on.

7 Parallel with the shaft 3 there is another shaft 21 which, because of the fact that it makes but a partial revolution in operation, will hereinafter be referred to as a rock-shaft. One end of this rock-shaftis carried by a pointed bearing 22 consisting of a cylindrical block housed in a fixed sleeve 23 upon a suit able support coming from the base plate of the machine, which latter is not shown in the drawings. The block 22 is pirided with a. reduced stem 24 extending through the sleeve 23 and also through a bushing 25 havin exterior threads fitted to other threads tapped into the end of the sleeve 23, and this bushing is held in place by a lock nut 26. Surrounding the stem 24 within the sleeve 23 and confined between the end of the block 22-and the inner end of the bushing 25 there is a helical spring 27 Fast. on the rock-shaft 21 adjacent to the bearing 22 is an arm 28 connected by a suitable spring 29 to a bracket 30 fixed on the support of the sleeve 23 or coming from any other adjacent fixed portion of the machine, and the spring 29. is of sufficient strength to at all times tend to rock the shaft 21 in a direction to causethe arm 28 to approach the bracket 30. About midway of the length of the rockshaft 21 it is formed with a piston 31 and the roek shaft carries a hollow cylinder '32 inclosing said piston 31. That end of the cylinder 32 toward the bearing 22 is closed by a packing; gland 33 inclosing suitable packing 34 to render this end of t ie-piston air-ti ht end of the piston closed by a simple screwhead 35 serving to maintain the cylinder in concentric relation to the shaft 21. In order that the cylinder 32 ma not turn upon the shaft 21, although movable longitudinallv thereon as will hereinafter appear, the shaft 21 is provided with a spline 36 passlng through a suitable slot in the head 35. T lllS spline 36 is of sutlicient length to permit the full longitudinal movement desired for the cylinder 32.

The end of the rock shaft 21 remote from the end supported by the bearin' 22 s formed into a head 37,the end face of w ch is curved The other,

on the erect a circle, and this end face fits the similarly curved face of e fixed bearing 38 on the end of a stan ard 39 fast on the base or other fixed partof the machine. The hear;- ing 36 is best shown in Figs. 9 and 10. EX- tending" through the shaft 21. from the head 37 to and through the piston 31 is a conduit 40, and this conduit at the head 37 opens into a port 41. The bearing 38 is provided with a through port 42 and another port 43 alongside of the through port 42 but leading mdially,. by means of a duct 44, through the bearing to a coupling head 45 from which. leads a pipe 46 to a source of air supply under pressure, which may be the air pressure supply for the brake system of the train and for other purposes. Now, when the rock-shaft 21 is moved about its axis in the manner to be hereinafter described, the port 41 will be brought into coincidence with one or the other of the ports 42 and 43 in the hearing head 38. The sound r'producer box 10 is secured to the cylinder 32 by means of an arm 47 so as to be supported-by and move with said cylinder, and the arm 13 carryin the half-nut 12 is likewise secured to said cylinder to be supported by and move therewith.

The relation of the several parts is such 'thatwhen the rock-shaft 21 is moved under the action of the spring 29 and-the cylinder is likewise moved with the rock-shaft, the port 41 is brought into coincidence with the port 43 and air under pressure therefore admitted by the conduit 40 t0 the side of the piston 31 adjacent to the packing gland 33. The result is that the reaction of this compressed air will force the cylinder toward the right as viewed in Fig. 1 and this movement will continue until stopped by means to be hereinafter described, which means also cause the movement of the rock-shaft 21 on its axis in a direction to bring the sound-box into operative relation with the beginning of the sound record 1 and to bring the half-nut 12 into op-- erative relation to the screw-threads 1 1. This last movement of the rock-shaft 21' brings the ort 41 into coincidence with the port 42 in r the head 38 and as this port 42 is open to the air the sup ly of compressed air within the cylinder, a iitted through the conduit 40, now exhausts through the port 42' and the cylinder is free to be moved under the action of the screw-threads 11 and nut 12 in a threetion to cause the reproduction of the sounds recorded in the tablet 1.

In order to provide for the maintenance of the half-nut 12 in contact with the screwthreads ll and for the maintenance of the sound-box 10 in operative relation to the rec- 0rd oove in the tablet 1, and to disconnect both the half-nut 12 and the sound-box 10 from their respective arts of the reproducing mechanism when t e'end of the record is reached, and to return the sound-box and half-nut to beginning of the-record and,

this means being shown in Figs. 1, 4, 5, 6, 7 i

and 11.

Fast on the cylinder 32 about midway of its length there is an arm 48 projecting in a direction opposite from that of the arms 13 and 47, and this arm 48 terminates in a roller 49. In the ath of this roller there is a track 50 suitiibly supported u on posts 51 rising from the base plate or ot ier fixed portion of the machine, and at a higher level and overlying the track 50 there is another track 52 secured to the track 50 by yokes 53 and to one of the standards 51 by a yoke 54, the two tracks thus being parallel but )aced apart, while, for a purpose which will hereinafter appear, the track, 52 is shorter than the track 50 and terminates at one end 55 at a short distance from an upturned end 56 of the track 50 to form a throat 57 between these ends of the tracks, while at the other ends the tracks terminate in the same verti cal plane. The upper end of the standard 51 adjacent to the two matched ends of the track sections 50 .and 52 is formed with a dovetail slot 58 receiving a dovetail tongue 59 on a sliding block 60 movable from a osi: tion coincident with the top of the two .50 to a point coincident with the top of the track 52.

It will be observed that the top of the track 50 is level while the top of the track 52 is inclined, as indicated at 61, and the top of the block 60 is formed with an upturned stop lug 62 and the u per end of this block 60 is also inclined, as s \own at 63, similar to the inclined face-61. Now, let it be so posed that the roller 49 is traveling along t e inclined track surface 61. In this position the roller itself is inclined and bears evenly on said track. The direction of travel of the roller 49 under the impulse of the screw 11 is toward the left as viewed in Fig. 4, and ultimately this roller reaches the throat 57 and drops down therethrough to the track 50. Since the arm 48 carryin the roller 49 moves through an are about t 1e axis of the rock-shaft 21, the drop from the track 52 as the track 50 brings t e roller 49 into good bearing contact with the level surface of the v track 50. In,this position of the parts the cylinder 32 is impelled by the air pre sure toward the rightas viewed in Figs. 1 and 4,

and the roller therefore travels toward the -Within the cylin er there is located a piston 67 at the lower. end of the piston-rod 68 passing through a suitable scrow-plu; 69 at the vided with aside stud 72 engaging in a suitable bearing 73 formed in a lever arm 74 pivotally supported in one portion 'of the twinhead 66. This lever armis extended beyond its bearing in the twin-head 66 and isthere rovided with an angle arm 7 5 terminating in an eye 76 receiving one end of a spring 77 to be hereinafter referred to. The other end 'of the lever 74 is formed into a head 78 arranged to engage under the block 60, and a stop 79 formed on one end of a bracket 80 extending downward from the track 50 1s arranged in the iath of this block 60 so'that it may descend fon'only a definite distance which is sufiicient to bring-the track surface 63 coincident with the surface of the track 50. The lower end of the cylinder 64 receivesthe end of a ipe Slcoming-froni a" valve mechanism to e presently described. The action of the spring 70 before referred to is to depress the piston 67 and thereby ca the lever 7.4 to its lowermost position unt' the block 60, which is of suilicient weight to fall by gr. vity, is arrested by the stop 79.

kivotally supported in the twin-head 66 is another lever 82 having an arm 83 extending away from said head and connected to the end of the s ring 77 remote from the end connected to t e arm 75. The other end of the lever 82 ispivotclly connected to a slide 84 mounted at the lo rer end in a suitable guideway in the bracket 80 and at the upper en passing through a suitable guidcway in the corresponding end of the track and adjacent to the block 66.

' Assuming that the piston 67 is at its lowermost oint of travel, the lovers 74 and 82 are also epressed and the block 60 has its track section 63 coincident with thefi'track 56, and the slide 84, the upperend 85 of which is shaped as shown, is also lowered to such an extent that the said end 85 is below thelevel of the upper surface of the track 50. I

Returning now to the roller 49, which z'v hen last spoken. of was supposed to be a preaching the end of the track adjacent o the block 60. This roller, continuing its t avel toward the .right, ultimately passes upon the track section 63 of the block 60,

being stopped by the log 62. When the roller has reached this point it has caused, in tail-18111161 to be presently described, the a r to be admitted through the iipe Site the lower side of the piston 67 in t 1e cylinder 6-1.

'This air coming from the train service pipe is under pressure and lifts the piston 67 against the action of the spring 76 and thereby causes the lever 74 to alsov move upward. However, the head 78 of the lever 7-} is so related to theblock 66 that in theiuitialpo sition of the lever 74 the head is some l istance below the lower end of the block so. Consequently, the lever 74 mustmove some. little distance before it engages he bloci; 6U.

lhis causes the arm 75 to move awayirom the arm 83 and thereby the spring 77. put under tension until it overcomes the weight of the lever 82 and the slide Si, which latter is moved up until it reaches the lower side oithe track 52 in which position i: is in the pat h of the roller 49 and the latter is eilecinally revente-d from returning to the truck 50. by the time this movement has been accomplished the head 78 of the lever 74 has come in Contact" with the. block 60 and then the continued upward movement of the piston 67 forces the block 60, together with the roller-49 and arm 48, upward until the track section 63 is coincident with the inclined surface 61 ofthe track 52, the end of the track 52 preventing the roller 49 from elevatin the track 63 after it has passed the upper en 7 85 of the slide 84.

New, in order to insure the operation of the piston 67 there is provided in the bracket 80 a val e mechanism by means of which air coming from a suitable source of air pressure through a pipe 86 is directed to the pipe 81 and then the air supply is cut oil from the pipe 81 and the air in the cylinder 64 is permitted to escape. For this purpose there is mounted in the bracket 80 a rotary alve, best shown in Figs. 6 and 7. This valve consists of a fixed seat member 87 and a rotary member his held to the member 87 by'lneans of asuitable screw 89, and theroury valve member 88 is held in a certain normal position by means of a spring; 90 carried by the screw 3? and engaging said rotary member 88. Fast on the rotary member SSthere is an arm 91 having an extended bearing surface 92 arranged to engage in a recess 93 in the track 50, but normally held out of this recess by the spring 90 before referred to, a stop-screw 94 determining the ei'rtent of travel of the arm 91 away from the recess 93.

The fixed member 87 of the valve is providcd with two ports 95 and 96,the port- 95 being: in communication through a suitable duct QT'Wit-h the air supply pipe 86, n'hile the ort 96 is in communication throu b a suitable duct 98 with the pipe 81 leading to the cylinder 64. In the fact of the valve member 88 there is formed an arc-shaped groove 99' i holds it. in close contact with the member 87.

One'end of this spring may be carried around I against the pin or screw 94.

Y through the groove 99 and the piston 67 is path of the oncoming roller 49. Before,

- g5 surface 92 of the valve member 88 and, de-

3o exhaust port 100into coincidence with the I. piston 67 is depressed by the spring 70.

' fall and the block .60 also falls until arrested 84 has likewise been depressed until its end doblock 60 is in line with the top of f he track 45 turns on its axis under the impulse ofthe I i slide 84 to be projected into the path of the ately afterward the end 78 of'the lever 74 movement of the roller 49 acting through the p5 stylus of the sound-box 10 into engagement niakqan air-tight joint, and the member 88 '18 held with its face against the face of the 'member 87 by means of the spring 'which presses against .the movable member 88 and a pin .or screw101 on the member .88 in such manner as to hold it in position to close all theports, m which position the arm 91 abuts When the valve just mentioned is in its normal position the bearing surface 92 is in line withthe track 50 but extends above the, same in the path of the oncoming roller 49,:

15 However, in this position of the. valve the ports and 96 are in communication therefore acted upon bythe compressed air and the block 60 is in its uppermost position, 20 as shown in Fig. 4. Moreover, the slide 84 is also elevated so that its end 85 is in the owev'er, the roller 49 reaches thestop end 85 of the slide 84 it passes upon the bearing pressing this bearing surface 92, causes the valvememberSS to turn uponits axis to asuflicientextent to carry the groove 99 out of coincidence with the port 96 and to bring the port 96. The air inthe cylinder 64 is theref re exhausted through the port and the This action causes the levers 74. and 82 to by the stop'member 79. Moreover, the slide 85 is outof the path of the roller 49. Under these conditions the tracksection 63 of the andthe roller is free to enter this track section '63. Now, however, the roller has .passed oil from the bearing surface 92 of the 'valve member 88 and this latter memberspring 90. The first action is to connect the ports 95 and 96 with the .compressed air supply and compressedair is introduced below thepiston 67. This latter member then 50 rises, first putting the spring 77 under tension and thereby causing the end 85 of the roller 49, thus preventing the latter from again moving on to the track 50; Immediengages the lower end of the block 60 and elevates the same, togetherlwith the roller 49, to coincidence with the surface 61 of the .track 52. As befdre stated, the upward arm 48 has caused the cylinder 32 on the shaft 21 to rock upon the axis of the latter, thus bring the half-nut 12 into engagement a with the threads 11 and the reproducing with the beginning of the record groove on the record tablet 1. Now, as the shaft 3 is rotated in a manner to be described the sound-box 10 is fed across the record tablet in operative relation with the be 'nning of the record tablet in the manner a ready described.

Before passing on to the description of the 30 driving incchanism for the structure just described, it may be well to note that the packing 3.4 for the cylinder 32 need not be thoroughly air-tight since there is a large excess of power from the air entering said cylin- 85 der and some leak at this point is immaterial. But it is material that there should be as little friction as possible in the active movement of the cylinder 32 when propelled in the proper direction to cause the reproduc- 9o I tion of the record under the action of the screw 11, since now the air pressure no longer acts directly to furnish the propellin power, and, therefore, it is advisable to re ucethe resistance at all points where there may 95 resistance offered to the o eration of the ma-- chine. For this reason t. e packing 34 may be of any suitable substance that Will answer the purpose and a good, loose graphite packing may be sufficient. 100

t will be observed that the shaft 21 has its bearing 22 constantly urged toward the shaft 21 by the spring 27. This serves to maintain the contiguous faces of the head 37 and the bearing 38 in close contact, and as these faces are carefully ground to an air-tight fit such fit is maintained by the spring 27 during the rotative movement of the shaft 21. It

is advisable to retard the movement of the cylinder 32 on its return movement to the position to bring-the sound-box to the beginning of the record. When the roller 49 falls through the throat 57 the half-nut 12 is not immediately lifted out of engagement with the screw 11 because of the action of the spring 19 which causes the said half-nut to remain in contact with the screw 11 until just an instant before the roller 49 reaches the bottom of the throat 57 in po ition to enter u on its return travel along the track 50.

I owever, the port 43 has been brought into coincidence with the port 41 and air pressure is established inthe end of the cylinder 32 be yond the piston 31. Ordinarily, the cylinder 32 would move quickly along the shaft 21 but there is quite a body of air confined between the piston 31 and the head 35 of the cylinder.

This head 35 fits the shaft 21 sufficiently close to form a good hearing but there is provided a certain amount of leak. .The air i confined air past. the head 35 will permit. A

more rapid movement may be obtained by a suitably throttled by-pass for the. air through this head 35, but as this is a simple mechanica? expedient it is not thought necessary to show it in the drawings.

- No attempt has been made throughout the drawings, either in those already considered or thoscto be considered, to show exact proportions, and it will be understood that the proportions and even the relations of the parts may be varied as may be found expedient in the installation of a structure cm-' bedying the present invention under the varying conditions that may prevail in practice.

When the phonographic annunciator is established upon a car an ordinary amplifying horn may be used, but by preference there'will be small sound-directing horns located adjacent to each seat in the car, and thesehorns will be connected to sound-con duits arranged along the walls of the car in any suitable manner. For instance, the annunciator may be located at any convenient oint and sound-conveying tubes coming rom the sound-box may be "located along each side of the car with the small sound-directing horns coupled up in multiple to these tubes. As this 1s an evident arrangementfor the purpose, it is not thought necessary to Show it in the drawings.

As before stated, it is not expedient to use a spring motor for the purpose of driving the mechanism heretofore described andsince in the connection in which the annunciator is designed to be used air under pressure is available, and, in fact, is necessary for the operation of certain of the structures already described, we have devised a motor especially designed for driving the mechanism connected with the sound-reproducing ap aratus used in our an'nunciator, this mec ianism having a special coaction with the other parts of the device for the roper operation pf-thse said othcrparts in t :e manner neces sary for the accomplishment of the purposes we have in-view. This driving mechanism is shown in Figs. 2 and 3, to which special reference is now had.- In F' 2, there is shown a 'driveshaft 3 with t 1e pinion 20 mounted thereon, and the mandrel 2 and cylindrical record 1 are also shown. Thepmion 20 is engaged by a gear wheel 102 mounted on an arbor 103 which, in turn,

- carries a pinion 104 adjacent to the gearwheel arbor 106, which latter carries a pinion 107 meshing, in turn, with a gear wheel 10S mounted for rotation upon another arbor 109 but not connected thereto except as hereinafter set forth, and the last-named shaft carries a pinion 110. Meshing with the pinion 110 there a rack-bar 111 extending radially from one side of a shaft 112 passing at one end through a suitable support 113 fast upon a fixed portion of the machine. This shaft passes into a cylinder 114 through a suitable packing gland 115, and within the cylinder the shaft 112 carries a piston 116. Formed on one side of the cylinder 114 is the slide-valve box 117, which may be cylindrical in shape and formed originally with one end open but shown closed by means of a screw-plug 118 over which is placed a cap 119 to protect the same and revcnt mallcious manipulation thereof. he other end of the valve box 117 is provided with a screwplug 120 extending both to the interior and exterior of the valve box and covered at its outer end by a cap 121. The inner end of the screw-plug 120 ls..'.provided with an axial stud 122 forming the seat for one end of a. helical spring 123, which latter, at the other and, engages a piston-124, and this s ring is centered on said piston by means 0 a stud 125. The piston 124 is fast on one end of a piston-rod 126, the other end of which is supported by a disk 127 fittin the interior of the slide-vaive box 117 su iciently tight for guiding purposes. Between the piston 124 and the disk 127 the rod 126 carries a slide valve 128 of usual construction, and the latter is constrained to move with the rod 126 by means of collars 129 on said rod at each end of the slide-valve. The interior of thc-slidevalve is hollowed out, as indicated at 130, to form a passage, similar to the slide-valves found in ordinary steam engines.

The slide-valve box 117 is in communication through a passage 131 with a source of compressed air which may be the train supply coming at seventy pounds pressiire, and this air supply source may be the same as that before referred to with reference to the other figures of the drawings.

That end of the slide-valve box between the inlet opening 131 and the piston 124 is in;

communication with the end of the cylinder the piston 116 connected with the piston-rod 112, by means of a passageway 134, and in this passageway there is provided a throttlevalve l35 the purpose of which win hereinafter appear.

At the end of the cylinder 113 through which the piston-rod asses there is an end extension 136 in whic i is formed a chamber 137. The wall 138 of this chamber adjacent to the cylinder 114 is provided with a through passage formed into a valve seat in which 2 i axial extension7142 on the side opposite the stem 140 and this extension is seated in a suitable socket formed in a screw-plug 143 'in the outer end wall of the chamber 137. and

this screwlug is protected by a cap 144 similar to tose before mentioned. Extendin from the inlet'opening 131 of the slideva ve box 117 is a. passage 145 leading to the chamber 137, so that the air pressure within the chamber 137 is the same as that within the slide-valve box 117. 4

Referring once more to the gear-train, the arbor 109 has fast thereon in addition to the gear 110 a ratchet wheel 146. Of course,.

adjusted for the urpose, the air pressure on the 'sring side 0 the piston 142 accumulates 4 the gear'wheel 108 may be fast upon 'the arbor 109 and the ratchet 146 and pinion 110 may be formed in one piece and secured toet er*and mounted loosely on the arbor 109.

ivotally supported on the gear wheel 108' are a number of pawls 1'47 arranged to engage the teeth on the ratchet wheel 146 and maintained in normal contact therewith by springs 148. Now, when the piston 116 is moved toward the gland end of-the cylinder 114 in a manner to 'be hereinafter described, the rack 111, engaging the inion 110, will cause the latter to rotate and the said pinion 110, fast on the ratchet wheel 146 either directly or through the arbor 109, will impart rotation said ratchet wheel 146.

; Under these conditions, the pawls 147 are in j 15 eng ement with'the teeth onthe ratchet whee 146, and, therefore, the gear wheel 108 participates in the movement" imparted to' the pinion 110 b the rack 111. As the arts are viewed in ig". 2, the movement 0 the gear 108 is counter-clockwise. The rotation. of the gear wheel 108 imparts motion to the" other gear wheels 105 and 102 in order, and finally this motion is imparted to the shaft 3 whichdrives the sound reproducer and the tablet operating in conjunction therewith. When the, iston 116 moves in theopposite direction, t at is, away from the gland end of the cylinder 114, the rack-bar 111 rotates the pinion 110 and ratchet wheel-146 in' the opposite direction but, as will be readily understood, the pawls 147 are now inactive.

and thegearl'wheel 108 and the restof the gear train remain stationary. It maybe p re stated that this motive apparatus is designed to cause a sufiicient number of rotations of the record cylinder 1 to reproduce all the recorded sounds thereon from one end to the other by the movement of the piston 116 on its power stroke once through the length of the cylinder 114. Now, let it be assumed that the piston 116 is in the cylinder at the end remote from the gland end. Under these circumstances, compressed air enterin through the opening 131 into the interior 0 the slide-valve box 117, acting against the piston 124, holds the slide-valve 128in a position to clear the port 133. The compressed air therefore enters back of the piston 116 and ur es the same toward the gland end of the cyhnder 114. This movement continues until ultimately the piston 116 reaches thevalve stem 140 when a still further movement of the piston 116 opens the valve 139 against the air pressure in the chamber 137 and puts the said air chamber 137 in communication with the piston-rod side of the piston 116. The pressureon both sidesof the piston now begins to e ualize and the compressed air coming from t e chamber 137 also travels through the passage 134 to the spring side of the piston 142 but because of y t e throttle valve 135 which may be properly but s owly owing to the sluggish passage of the compressed air into the slide-valve box on the spring side of the piston 124, and the 'airon .t

e'piston-rod side of the piston 116 has time to-come up to full pressure. -Now,

when the pressure in the slide-valve box on to the pressure and couple this port to an exhaust port '-1.4 9 communicating with the external atmosphere. The air'pressure on the piston-rod'side of the piston 116 now returns that iston to its normal position, causing the inion' 110 and ratchet disk 146 torevo g i such that by the time the piston 116 has ve i y. The proportions of the parts are reached its initial position at the rear of the cyhnder 114 the pressure in front of it has reduced to about or very little aboveatmospheric pressure. 4, I I During the forward motion of the iston 116 the air in front of this piston, has eaked out through -.the g1and115; the packing of which is pu osely made somewhat loose to permit this eakage, but this leakage is too smallto have any material effect when the air pressure is established in..frant ofthe piston, and the same is true with regard to the piston 124'. "Thepiston 116 has been moved rapidly to the initial position and the pressure in front oi has rapidly dropped but the pressureon the spring Bldg-bf the iston 124 has not dropped rapidly,because of the thrpttling action of the valve 135,

which latter is so constructed as to be turned to any desired position to cont-rolits throttling action. The result of this is that. the piston 116' will reach its initial position before the ressure on the spring side of the piston 124 v able to overcome the resistance of the ring 123 and move the shdewalve sullicient y to again open the port 133 to the compressed air supply. In the meantnne. and w nle the piston 116 is moving away from the forward position toward the rearward or initial position the drop in pressure on the front side of the piston l 1.6 has caused the valve 139 to be seated and thus prevent any morewunpressed air reaching theironi side of the piston from 5 v the clnunber 137.

wehave devised t1:

In considering the-forward movement of the 1181011 116, whereby motion is imparted to t 9 gear train andso to-tbesountLreproducing mechanism, it is to be noted that in the practicaloperation of the invention this motion is 'not continuous but intermittent,

and the parts are so proportioned that one forward power stroke. of the piston will occu )y' the time taken for the entire run of a car t rough the entire distance covered by the announcements contained on the record c'linder 1. Now; in order to provide'for t is starting andstopping of the phonographic reproducer mechani m at the propcr'times, instrumentalities which we will now proceed to describe.

by easy curves. I

. tures. Since this govprnoi' may be of any Secured upon the. spokes of the gear wheel 105 there is an annulus 150 having on its peripherya number of spaced teeth 151 com-distantly disposed. These teeth are. formed on one side with abrupt shoulders radial to the axis of the gear wheel 105, and on the other side these teeth are approached a proved type and in itself forms no part of t e present invention," it has been omitted from the drawings. On the governor shaft 1.53 there 15 mounted a disk 154'-aga1n:.. the

i periphery of which a suitable brakemay be 'made to engage. In the drawings this brake is shown in the form of a pad or block 155 of suitable material, such as leather, projecting from a suitable. seat in a cup156. This cup is carried in the end of a screw 157 passing through a boss 158 formed on the end of an arm 159. .A finger-160 is-formed on one side of the boss 158 and serves to guide and prevent the taunt ng of the cup 156 when adjustedjzo or from thedisk-154 by the screw 157. a

has dropped to such an extent that the pressure. on the other side of this piston is i l I l shown in the drawings.

clamp the screw 157 in its adjusted positions. The arm 159 constitutes one arm of a lever 162 pivoted at 163 to a suitable fixed portion of the framework of the machine. The lever 162 is under the control of a spring 164, the normal tendency of which is to move the malt" pad 155 away from the. brake disk 154, and the arm 159 is thinned so that when the brake pad 155 is in engaget'ient with the brake disk 154 it presses against the same with a yielding or elastic )ressure. The other end of the lover 162, that is, the end remote from the arm 159, carries another lever 165 by'means of a pivotal screw 166. The shorter arm 167 of the lever 165 is appropriately bent and carries a roller 168 in the path of the teeth 151 on the annulus 150. The longer arm of the lever 165 is connected to the longer arm of the lever 162 by a spring 169, and astop-screw 170, mounted on a stud 171, limits the extent of movement of the lever 165 under the action of the spring 169, while a set-screw 172 locks the stopscrew 170 in any adjusted position.

The lever 165 carries at the end remote from the arm 167 an armaturc'173 in operative relation to the core 114 of an electromagnet 175. The circuit connections in which this electro-magnet is included are not It suffices to state, however, that this magnet may be in a suit ably charged circuit receiving current from the .power circuit on the car or from indi-- vidual sources of current such as batteries, or m any suitable. manner,- and provision is made to close this circuit at intervals along the line of travel so that the'niagnet may be energized atprcdet-ermined points during the run of a car. the several parts the roller 16S rests against the outer end of a tooth 151 and the lever 162 is then in such position that the spring 164 is under ten ion and the brake )ad 155 is in contact with the periphery of te brake disk 154, thus holding the latter against movement. Now, let it be. supposed that a car has reached a point within a certain distance of a station and that by any suitable means the circuit of the magnet 175 has been closed so that the ma net is energized. The arma-.

brake shoe or pad 155 away from t e brake disk 154 and thus releases the gear train. Now, let it be assumed that the piston 116 is 111 the normal posit-ion of in its initial position and air pressure is establishcd behind it. The gear train now be- 65 A small set-screw 161' may be used to ing unlocked will star-tits movement under mcnt of the gear train continues until the next tooth 151 is reached, when the easy slope of this tooth will engage the roller 168 and move the lever 162 around its pivotagainst the stress of the spring 164 and ultimately bring the pad or shoe 155 into contact with the disk -1 with sufficient force to 1 stop the rotation of the gear train. hen 1.5 the next station or point where an announcement is to be made b the phonographic reproducer is reached t ie magnet 175 15 again energized and the operation just des =ribed is repeated, the piston 116 advancing a1 appropriate distance under the action of the compressed air. And so from time to time the 7 gear train is released whenever a predeter- -mined point is reached, and the announcements contained on the record cylinder 1 are 25 reproduced. The number of teeth on the annulus 150 depends on the announcements to be made, which, of course, will depend upon the conditions under which the annuncutter is established; that is, there may, for example, be ten teeth on the annulus 150 and the gear carrying it may make ten revolutions during one movement of the piston 1 16 and one revolution of the gear wheel driven by said piston and its connections, and thus the number of announcements made may then be ten times the number of teeth 151. V The constructionis such that when all the announcements to be made have been made stro e and it will then automatically return to its initial osition. Because of the slow movement 0 the piston during its power stroke it will be seen that the air 1n front of it easily escapes through the packing in the gland 115 and that this packing, while loose enough for such purpose, ma be sufiiciently tight to prevent undue lea age when the compressed air enters the cylinder in front of the piston through the valve 139.

From the foregoing it will be seen that in a system in which our present invention is embodied all announcements are made automatically without danger of confusion; and being produced from a phonographic record and directed to pointsclose to each passenger, theseannouncements will be clearly understood by each passenger on a car or train. It will also be understood that in the foregoing description we have used the terms phonograph and -"phonographic reproducer in the broad sense of sound reproducers and that these terms are not to have lar narrower sense as applied to any particuthe type of sound-reproducing lnachmes.

It sometimes tlk'adspires that it is desirable the piston 116 will have made one full power to silence the reproducing parts of the annunciator without, however, stopping the action of the otherparts. For instance, assume that the structure is mountcdirpon a sleeper. When the passengers are asleep it is desirable, of course, that they be not disturbed by the various announcements which would be made from time to time as the train passes stations, but at the same time the aparatus as a whole cannot be stopped, for, icing automatic in its operation, it would getout of step. Therefore, we have devised means whereby the reprodncer may be held out of operative relation with the record tablet so long as may be desired but will still be advanced along said tablet to the same extent as though the reproducer was in active operation. Then when it again becomes desirable to place the reproducer in operative relation to the tablet-it will be in the proper g5 relation thereto and continue the reproductions at the proper point, as though it had been in operative relation to the tablet duringithe intervening time.

eferring, now, to Fig. 12, 13 and 14, it

will be seen that the arm 47 is not fast upon the cylinder 32 in the strictest sense of. the word but is fast upon a collar 176 mounted upon' said cylinder 32 for a very limited rotative movement about said cylinder. This independent movement, however, is not sufficient to prevent the lifting of the reproducer head from the record during the return movement to the initial position at the commencement of the record. The collar 176 has on each side short ecesses 177 through which. pass screws or studs 178pro-jecting from the cylinder 32, so that the collar 175, while confined to one plane, may move about the cylinder 32 in such plans for a very limited distance, depending upon the length of the recesses 1 77. i

Projecting from one side of the collar 176 is a stud'179 carrying a roller 1S0. Upon the other side of the cylinder 32 opposite the roller 110 180 is a horizontal rock-shaft 181 mounted at its ends in journal bearings formed in standards 182 which may rise from the base plate supporting the entire structure. Fast upon the shaft 181 near its ends and adjacent to the journal hearings in the standards 1 82 are curved arms 183 bent so as to pass down under the cylinder 32 and thence up, and at the ends ofthcse arms 183 remote from the shaft 181 they carry a track 184 in the ath of the roller and of s'uilicient lengt to engage said roller under conditions to be hereinafter named, during the entire length of travel of the reproducer over the record. Fast upon the shaft 181 is a dependiirg arm 185 carrying at its free end an armature 186 in operative relationto the poles of a horseshoe electro-magnet 187, t is yoke 188 of which is fast upon a post or bracket 189 secured to thelbase plate of the machine, which ,130

Pivotally secured tot e base of the 90 extending upward and suitably bentfor the purpose and terminating in a head 191 formed at a short distance below its upper end with a. notched off-set 192 on one side and at the -.extreme upper end with a supporting end and limiting finger 193. The upper end of -the head 191' is shaped to receive and hold the track 184. and about midwav of the length of this track it is formed \vitha short,

source of the car, which source forms a art of our complete traction system. 0th

magnets 187 and 197 are connected to 'a condoctor 202 leading from one side of the. current source 201. The magnet 187 is connected on its other side 'by a conductor 203 to one member 204 of a push-button or switch 205, the other terminal of which is connected by a conductor 206 to the other The magnet 19? also has the terminalremote from that connccted' to the currentsource, connected by a conductor 207 to one member 208 of a push button or switch 209, likewise i-onnected by the conductor 206 to the current source.

In the normal operation of the structure the' track 184 is out of engagement with the l'r'l' r 180 and is then supported by the engagement of the pin 195 with the notched oil-set 192 of-the arm 190. Under these conditions, the mechanism will operate to make the announcements. audibly in themanner already (Rscribed. Now, let itbe supposed that it is desirable to silence the :.:muncintor without stopping its operation inputting it out of step. Forthis purpose it is only necessary to complete the circuit'at the push-button or switch' 205. when the magnet 1.\T will be energized and its armature 156 wil be attracted. By this means thc'urm 1% is drawn toward the magnet- 187., thus causing the shaft 181 to rock in its hearings and the track 181 is thereby lifted until it engages the roller 180 and causes the collar 176 to be rotated about the cylinder 32 to the extent permitted by the length of the recesses 177. This movement is sufficient to not interfere in the least with the operation of the remainder of the structure, so that the repro'ducer head is moved fromtime to time the same as though it were in engagement with the record 1. Itmay be noted that the. upper face of the track 184 is slightly beveled, so that when in engagement with the roller 180 and the latter has been lifted usdcscribed, it may engage evenly with the bearing surface of the track.

When the track 184 is lifted the pin 195 participates in the'niovement and thus is ifted out of the notched oil-set 192 and moved upward alongside of the head 191 until the upper end thereof is reached. when. under the action of the spring 200, the arm 190 is moved to an'ext-ent to cause the head 191 to ride under the in 195 until stop ied by the tooth 193. e track is thereiore locked inthe elevated position. so that the push-button 205 can then be safely released to open the circuit at that ioint. Suppose, now, that the time period during which it is desirable to silence the annunciator has passed. The push-button or switch 209 is now manipulated to close the circuit from the current source 201 and then th magnet 19? is energized, thus drawing the armature any time desired it is possible to stop the audible action of the annunciator 'without interfering in the least. with the continued action of the rest 0?. the mechanism of such annunciator. Ther'efore, when the annunciator is again put into audible operation the announcementswill begin at the proper point the same as though the audible parts of the ammnciator had not been put out of action.
