Specication of Letters Patent.

Patented Mar. 26, 1912.

Application filed December 5, 1911. Serial No. 663,983.

To all fra/0m t may concern Be it known that I, JOHN Ianni-nuit, citizen of the United States, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Iinprove'n'ients in Type-lVriting Machines, of which the following` is a specification.

My invention relates to typewriting,I machines and more particularly to taloulating mechanism.

One of the main objects of my invention, generally stated, is to provide a comparatively simple and efficient tabulatinp,` mechanism by which any desired columnar` position may be selected at will and by which any desired denominational position in a column may be selected so that the carriage may, after a single run, be arrested at any desired columnar eld and at any desired denominational position within anyselected columnar field.

A further object of my invention, generally stated, is to provide comparatively simple and efiicient means whereby certain parts of the tabulating mechanism may be locked in the position to which the said part or parts may be set or moved under key control, aiid to automatically release the lockingr means before the completion of the tabulating` operation.

A still further object of my invention, generally stated,-is to provide means whereby the carriage releasing means controlled by the tabulating; mechanism is normally rendered inoperative to release the carriage and is rendered operative by the preliminary actuation or setting` of the column selecting mechanism.

Another `object of my invention, stated in general terms, is to provide automatically operating` locking means for a part of thek tabulating mechanism and to automatically effect a release of the locking' means by the travel of the carriage.

To the above and other ends which will hereinafter appear, my invention consists in the features of construct-ion, arrangements of parts, and combinations of devices to be set forth in the following` description and particularly pointed out in the appended claims. y

In the accompanying` drawings, wherein like reference characters indicate correspondng parte in the various, views, Figure of a part of the tabulator mechanism.

Fig. 7 is a detail fragmentary rear elevation Fig. S is a transverse, vertical, sectional view of the machine taken on the line g/-g/ of Fig. 1 and looking,` in the direction of the arrows at said line.

In the accompanying drawings I have shown only so inuchof a typewriting machine as may be necessary to arrive atan vunderstandingv of my invention.

I have illustrated my inventori in the present instance embodied in a No. 15 Yost machine except in so far as the tabulating mechanism of that machine may be modified or replaced vbyfeatures of the present in vention; and except in so far as that niachine may be modified to effect an einbodiment of my present invention therein. Moreover, some of the parts of the typewriting' machine are conventionally represented in order to simplify the showing. It should be understood, however, that the invention may be embodied in variousvstyles of typewriting machines and that various changes may be made in the coiist-ruction to facilitate such embodiment.

The present case is one of three companion applications tiled by me of even date herewith, the other applications .bearing Serial Numbers 663,982 and 663,984 respectively. Considered from cert-ain broader aspects there are features in common in all three cases. The broaderA claims to features incommon to all three applications are ineluded in case Serial No. 663,982, whereas any feature common alone to case Serial No. 663,984, and the present application are broadly claimed herein, the claims in case Serial No. 663,984 being restricted to features not disclosed in either of the other said companion applications. Nevertheless there are certain features disclosed in my case Serial No. 663,982 that are not claimed therein but are broadly claimed herein. Thus in the modification shown in Figs. 7 to 12 of my case Serial No. 663,982 a construction is illustrated wherein previously set or locked parts of the column selecting mechanism are automatically released by the travel of the carriage to enable such parts to be returned to normal posit-ion. This mechanism is not claimed in my case Serial No. 663,982 but is broadly claimed herein.

The frame of the machine comprises side plates 1, a rear cross plate 2 and top plates 3 and 4. The usual printing instrumentalities (not shown) are employed. A carriage 5 is mounted on anti-friction balls or rollers 6 to travel from side to side of the machine under the power applied thereto by a spring drum 7. The carriage carries a cylindrical platen 8 adapted to receive the impression of the types against the front face thereof. The usual escapement mechanism may be employed to control the step-by-step letter feed movement of the carriage. have only shown so much of the escapement mechanism as may be necessary to arrive at an understanding' of my invention. Thus the feed pinion 9 is cooperative with a feed rack 10, mounted on arms 11, pivoted at 12 to depending lugs 13 on the bottom of the carriage, A coiled spring 14 is connected at one end to on-e of the lugs 13 and at the opposite end to one of the depending arms 11, to force the feed rack into engagement with the feed pinion. A crank arm 15 extends upwardly from one of the arms 11r and is connected to a rearwardly extending link 16 which in turn is pivoted at its rear end, as at 17, to a depending` arm 18 which constitutes one of the supporting arms of a release bar 19 which extends throughout the length of the carriage. The arms 18 are pivoted at 20 on bracket arms 21 which eX- tend upwardly from the carriage and constitute a support for a column stop bar 22. It will thus be understood that the forward movement of the bar 19 will transmit movement through the link 16 to the feed rack, to effect a rearward movement of the feed rack, thereby disengaging it from the feed pinion. The column stop bar is provided with teeth 23 on the front and rear sides thereof to provide interdental spaces for the reception of bifurcated column stops 24. one of said stops being shown in detail in Fig. 6. From an inspection of Figs. 1 and 2 it will be observed that the engaging portions 25 of the column stops extend rearwardly varying distances from the column stop bar, the longer st-op being situated at the right and the stop having the shortest engaging portion 25 being situated at the left of the series, so as to provide a series of graduated stops with which the denominational stops are adapted to be brought into coperation, as will hereinafter more clearly appear. It will be understood that the column stops are mounted for individual adjustment to different positions along the column stop bar.

In the present instance, I have provided column selectiilg mechanism by which the desired columnar field where thc carriage is to be arrested may be determined; and a denomina-tional key may then be actuated to move the denominational stop controlled thereby a requisite distance to coperate with the particular column stop to be brought into coperation with the denominational stop, as determined by the operation of the column selecting mechanism. I will first describe the column selecting mechanism. This comprises a series of column selecting keys 26, four being shown in the present instance, and as appears from an inspection of Fig. 4, these keys are provided with index numerals 1, 2, 3 and 4. These keys are preferably arranged in the rear of denominational keys 27 and in the rear of the usual printing keys at the keyboard of the machine. Each column selecting key is provided with a key stem 28 which is guided in openings in guide plates 29 and 30. Each key stem 28 is slotted to receive the forward end of a lever 31 to provide a connection between each key stem 28 and its associated lever, by which the lever may be actuated. A coiled expansion spring 32 surrounds each key stem 28 and bears at its lower end against the plate 30 and at its upper end against the associated lever 31, thus tending to move the forward end of the lever upwardly and' to restore the key stem and the parts connected therewith to normal position; the upward movement of the key stem being limited by an enlarged head 33 which engages the under face of the guide plate 30. The key levers 31 are fulcrumed on a pivot rod 34 carried by a frame 35, forming part of a cross bar 36 which is secured to the frame of the machine. The rear end of each lever 31 is provided with a stop face 37 with which a cross bar 38 coperates, and by which the cross bar is limited in its forward movement. Each key actuated lever 31 also has an upwardly extended rear end 39 provided wit-h an inclined face or cam 40 terminating at its lower end in an engaging nose or hook 41. Each extension 39 is off-set laterally from the body of the associated lever. Each lever 31 is likewise provided with a. bearing 42 in the plane thereof, said bearing being interiorly threaded to receive a screw, arresting stop or contact device 43, which is adapted to coperateat its forward end with the cross bar 38, as will hereinafter more clearly appear. The cross bar 38 constitutes part of a controlling device or arresting frame which includes upwardly extending arms 44 slotted at 45 to receive a fixed pivot 46. The upper ends of the side arms 44 are bent forwardly where they terminate in a cross bar 47. A contractile spring 48 is connected at one end, as at 49, to one of the Side arms 44 of the arresting frame, whereas the other end of said spring is connected to a pin 50 which projects from one of the two bracket arms 51, by which the pivot 46 is supported. The spring 48 performs a two-fold function, t'. e., it Vnormally maintains the arresting frame, comprising the cross bar 38, side arms 44 and cross bar 47, in the lowermost position where the upper ends of the lslot 45 are seated on the pivot pin 46. It also exerts a pull on the frame to turn it around the pivot 46 to the position shown in Fig. 1, where the cross bar 38 is arrested by engaging the upright contact edges or stop faces 37 on the key actuated levers 31. When the parts are innormal position the cross bar 47 is posie tioned, as indicated in Fig. 1, in contact with a fixed stop 52 secured to the rear fixed rail which guides and supports the carriage. It will be seen that thisv stop 52, when the parts are disposed as indicated in Fig. 1, prevents a swinging movement of the frame around its pivot 46' in one direction,.whereas the frame is prevented from swinging in the opposite direction by the cross bar 38 engaging the levers 31, at 37. It will be observed, however, that the frame is adapted to be lifted from the normal position by reason of t-he slots 45 in the side arms of the frame when a column selecting key 26 is depressed. The effect of depressing a column selecting key 26 is to shift the frame bodily upward to some such position as that indicated in Fig. 2. The shifting of the frame is effective to carry the cross bar 47 up out of contact with the stop 52, so as to enable the frame to swing forwardly at the upper end thereof, and to swing rearwardly at the lower end thereof. The upward movement of the frame is likewise e'ective to carry the cross bar 38 thereof out of coperative relation with all of the screw stops 43, except the stop which is carried by the lever 31'of the particular column selecting key which has been depressed, as indicated in Fig. 2. The cross bar 38 is there-y fore free at this time to receive a rearward movement, when the frame as a whole is turned on the pivot 46 in a manner to be hereinafter described. The extent of this movement of the cross bar is determined by the position of the forward end of the parcross bar 38 of the machine frame.

ticular arresting stop 43 which is carried by the lever of the depressed key. It will be seen that vthe forward ends of these different screw stops are arranged at progressively different distances from the front of the machine. Varied extents of rearward movement ofthe cross bar 38 from its normal or forward .position may therefore be effected under control of these arresting stops, the particular stop which engages the cross bar limiting and thus determining its extent of movement. This extent of movement of the arresting frame determines the extent of forward movement which may be given to each of the denominational stops, and tlnufe- `after determines which particular column stop the denominational stops may bc brought into coperation with, as will hereinafter more clearly appear.

In order that the arresting frame may be held in the elevated or operative position when a column selecting key 26 is depressed, I have provided automatically operating locking means comprising a member 53 which is in the nature of a universal lock i bar that extends between the two side arms 54, the latter being pivoted at 55 on the bracket arms 51. A contractile spring 56 is connected at one end to a pin 57 which projects laterally from one of the arms 54, the opposite end of said spring being connected to a pin 58 which is carried by a depending portion 59 o-f one of the bracket arms 51. The spring 56 exerts its force to cause the locking bar 53 to press against the inclined faces 40 on the levers 31, as indicated in Fig. 1. When any of the column selecting keys 26 is depressed, as indicated in Fig. 2, a corresponding lever 31 will be elevated at the rear end to shiftthe frame 23S- 44, etc., upwardly, in the manner described to bring the cont-act device 43, carried by said lever, into position for coperation with the This same movement is eective to cam the locking bar forwardly against the power of the spring 56 unt-il the `engaging nose 41 on the lever has been cleared when the spring 56 will cause the locking bar to snap under the engaging nose on the actuated lever 31, thereby locking said lever against return movement. It is desirable to retain t-he parts thus locked until an actuation of the denominational sto-p mechanism has been effected and then to automatically release the locked column selecting means to enable the parts to be restored to normal position. This release is effected in the present instance at the first tabula-ting o-peration by extending one of the arms 54 of the locking frame upwardly and forwardly to provide a releasing arm 60. This arm is preferably provided with an anti-friction roller 61 atthe upper end thereof, which roller is adapted to extend into the path of movement of cam faces 62 formed on a rearwardly extending finger 63 projecting from a depending arm 64 formed on each of the column stops 24, as shown in detail in Fig. 6. These actuating fingers 63 on the various column stops extend rearwardly equal distances from their supporting arms 64, so that any of them is copera-t-ive with the anti-friction roller 61 during the travel of the carriage and when the associated column stop reaches a position where engagement is effected between the cam carrying linger 63 and the anti-friction roller 61 on the releasing arm. further movement of the carriage after such engagement has been effected is operativo to cam the arm 60 rearwardly from the position shown in Fig. 2, thus moving the locking bar 53 forwardly to disengage it from the locked column selecting lever 31 and thereby enabling' the associated spring 32 to restore the released lever 31 to normal position. As soon as the engaged actuating linger 63 on the column stop passes the anti-friction roller 61, t-he spring 56 free to restore the locking frame to normal position where it is again disposed so as to engage the locking arm 39 on the next column selecting key lever, when the latter is actuated. I pre-fer to arrange the anti-friction roller 61 in such position that the finger 63 on each of the column stops will co-act with the roller and move the locking frame to the releasing posit-ion to trip oli' the lock at about the instant that the associated column stop is in position to coperate with the decimal stop of the series of denominational stops, for purposes which will hereinafter more clearly appeal'.

It is sometimes desirable'to render the means for automatically releasing the locking frame, just described, inoperative so that the carriage may travel indefinitely without affecting the release of the locking frame. In order to accomplish this result I have iixedly supported the pivot 55 of the locking frame in bearings 65 in two parallel links or ams 66, as will be seen upon reference to Figs. l, 3 and 7. Screws 67 may be employed to secure the pivot rod 55 in the bearing 65. The parallel arms 66 are pivoted on shouldered pivot screws 68 which are received at their threaded ends in tapped openings in the bracket arms 5l. The pivot rod 55 extends through slots 69 in the supporting bracket arms 51, so that the pivot rod is free to be shifted with the parallel links 66 from the position shown in Fig. 1 to that indicated in Fig. 3. In order to facilitate this change in the position of the pivot rod and to maintain it against accidental displaceiuent in either of the positions to which it may be shifted, I have provided a depending arm 70 on one of the parallel links 66. The lower end of this arm @M1163 EL lllurled head 7 1 fixed to the outer end of a sliding locking bolt 72. A coiled expansion spring 73 surrounds the bolt and is contained within a housing carried by the depending arm and bears `at one end against the housing and at its opposite end `against a collar on the bolt to force the locking bolt 72 into engagement in one or the other of two openings 74 and 75. In order to shift the pivot rod 55 from the position shown in Fig. l, to the position shown in Fig. 3, it is merely necessary to withdraw the locking bolt 72 from the opening 75 against the pressure of the spring 73 and to shift the frame, comprising the parallel links 66 and pivot rod 55, by means of the knurled head 7l, from the position shown in Fig. 1 to that indicated in Fig. 3. The spring 73 then becomes effective to move the locking bolt 72 into the opening 74, to retain the pivot carrying frame in the position to which it has been shifted. The effect of this movement of the pivot 55 is to move the arm 60 rearwardly to the position in Fig. 3, thus carrying the anti-friction roller 61 out of the path of the actuating lingers 63 on the column stops. It follows therefore that during the movement of the carriage, the actuating lingers are inoperative on the anti-friction roller and are ineffective to move the locking frame to the releasing position. It will be understood, nevertheless, that the locking frame is maintained in such position by its spring 56 that the bar 53 thereof is adapted to be engaged by the engaging arms 39 on the column selecting key actuated levers in the usual manner. It will be understood therefore that the depression of a column selecting key is effective to maintain the parts in such relation that the column selected by the depression of that particular key will continue to be used indefinitely. Vhen.y however, another column selecting key is depressed it is effective to cam the locking bar forwardly to the releasing position, thereby releasing t-he previously locked lever 31 and effecting an engagement between the subsequently actuated column selecting lever and the locking bar, so that the subsequently actuated leA ver will then be locked in operative position instead of the lever of the first depressed selecting key.

The denominational stop mechanism` and the means whereby different extents of fore and aft movement of each of the denominational stops is effected, as well as a release oil the carriage7 are yet to be described. The series of denominational keys 27 compris s, in the present instance. ten keys. each bearing an index character thereon` such as the Character-S 1 A 1o L 100, T i it 57 (C 7?: C( 777 it H7 C4 77 which indicate respectively the decimal key, units keys, tens key. hundreds key, and so on. Each of these keys is provided with a key stem 76 which is guided in the openingsy in the plates 29 and 30 and is provided with an enlarged head 77 at the lower end thereof t-o coperate with the lower guide plate 30, to limit the upward movement of the key stem and the parts connected therewith. Each key stem 76 is slotted to receive the forward end of an angular lever or key controlled member 78, pivoted at 79 on a pivot rod which is carried by the bracket or fra-me 35. Each lever 78 is returned to normal position by a. spring 78a. The upwardly extending arm of each of these levers 78 is provided with a forwardly extending pro-- jection 8O which, when the parts are in normal position, is situated back of the cross bar 47 of the locking frame, so as to lock all of the levers 78 against actuation. The upright arm of each lever 78 has pivoted thereto at 81, a denominational stop carrier 82` which terminates in a denominational stop 83. The upper ends of these denominational stops are guided in grooves or interdental spaces between downwardly pro-- jecting teeth 84 on a. guide plate 85, carried by a housing 86 which is fixed to the top plate of the machine by screws S7. The housing 86 carries forwardly projecting teeth 84 arranged between the stops 83. The denominational stops yare thus maintained separated and are guided in their movements fore and aftof the machine; the teeth 84 and 84a resisting the lateral movement of the denominational stops when impact takes place between a column stop and the projected denominational stop. Each denominational stop carrier 82 has a forwardly extending projection 88 to. which one end of a coiled contractile spring 89 is connected; the opposite end of said spring being connected to an arm or finger 90, carried by the associated denominational stop lever 78. From an inspection of Figs. 1 and 5 it will be seen that each denominational stop lever or key actuated member likewise has a laterally extending lug 91 thereon at its forward edge, and with which the asso-` ciated denominational stop carrier 82 is adapted to engage, to limit the forward movement of the denominational stop carrier relatively tothe key actuated lever which carries it. Each spring 89 therefore normally maintains the companion denominational stop carrier in engagement with the lug 91 on the associated lever 78, so

that the stop carrier and lever move togetherk as one part until the stop carrier is arrested, in a manner to be hereinafter described.

As hereinbefore explained, the cross bar 47 on the arresting frame is effected to prevent an actuation of a denominational key when the parts are in the normal position shown in Fig. 1. It becomes necessary therefore for the operator to first actuate a column selecting key 26 before the tabulator tional stop levers and into the path of projections 92y on the denominational stops or stop carriers, as indicated in Fig. 2. The projections 92 are integral parts of the denominational stops and may be regarded as parts thereof. This upward movement of the locking frame isV likewise effective to carry the bar 47out of engagement with the fixed stop 52 so that the arrest-ing frame is no longer locked against pivotal movement by said fixed stop. The column selecting key having been depressed the parts are automatically locked in the positions indicated by the engagement; of the locking bar 53 with the member 39 on the actuated column selecting lever 31, and the operator is free to actuate the desired denominational key 27. The effect of the depression of this key is to move the upright arm of the associ ated lever 78 forwardly, thereby projecting the extension 80 thereon through an opening in the fixed stop plate 52 and into engagement with the releasing bar or device 19, as shown in Fig. 2. This movement is eective to swing the bar 19 forwardly, thereby effecting a disengagement between the feed rack 10 and the feed pinion 9. This same depression of the selected denominational key is effective to produce a forward movement of the associated denominational stop carrier 82, by reason of the spring 89 which connects the denominational stop carrier with the actuated lever 78. This movement of the denominational stop carrier causes a swinging movement of the frame 38-44-47, by the engagement between the projection 92 on the denominational stop carrier and the cross bar 47 on the frame. This swinging movement of `the frame around its pivot 46 continues until the cross bar 38 ,engages the contact device 43 carried by the lever 31 which is maintained locked in the operative position. This limits the vpivotal movement of the frame and the frame arrests the denominational stop at the proper point in its forward movement where it is in a position to engage the particular column stop corresponding to the column selecting key which has been depressed. Thus,'by referring to Fig. 2 it will be seen that the fourth column selecting key, or that which bears the index numeral 4 in Fig. 4, has been depressed from the dotted line position indicated at a, thereby locking the associated lever 31 in the operative position,

as shown. This lever 31 carries a contact device 43 which extends forwardly farther than any of the other contact devices. It

follows therefore that the arresting frame 8S-44-47, when under control of this particular column selecting key and contact device 43, will receive less swinging movementy around its pivot 46 than when under control of any of the other column selecting keys and contact devices. It also follows that. when a denominational key has been subsequently depressed, as shown in Fig. 2, the arresting frame including the cross bar 47, will be arrested in its pivotal movement in a position where it will effect an arrest in the forward movement of the associated denominational stop at a point where the latter is cooperative only with the right-hand or fourth column stop, provided with the longest rearwardly extending contact face Q5, and that the denominational stop is maintained out of the paths of the contact faces of the remaining column stops. A depression of any of the other column selecting keys in a like manner operates to determine the extent of forward movement that may be given to each of the denominational stops, so that each denominational stop is coperative with the particular column stop that corresponds to the column selecting key which has been depressed.

It will be seen that the construction is such that the operator is required to first select a columnar field, by the depression of one of the column selecting keys before the denominational stop mechanism can be actuated. Although if the operator is continuously using a single columnar field, the automatically actuated releasing mechanism for the locking frame may be rendered inoperative by shifting the pivot to the position indicated in Fig. 3 and locking it in such position. Then the particular lever 31, which is controlled by the depressed column selecting key, will remain indefinitely in the locked position shown in Fig. 2, and the carriage will always be arrested in the same columnar field determined by the column selecting key. lt will be understood. however, that the denominational position of arrest in this or any of the other selected columnar fields is determined by the particular denominational key actuated.

I have hereinbefore explained that the anti-friction roller 61 is preferably arranged in such position that the fingers G8 on each column stop will co-act with the roller and move the locking frame to the releasing position to trip off the lock, at about the instant that the associated column stop is in a position to coperate with the decimal stop. By this arrangement I am enabled to bring about a coperation between any denominational stop with any column stop before the locking frame 53-54-6() is released. However, the construction is such that a. selected column stop cannot pass the entire group of denominational stops without automatically l a 1 I releasing the locking frame. 1f, for example, the mechanism be used merely as a column selector, none of the denominational stops except the decimal stop will be employed, but at about the time the projected decimal stop co-acts with the selected column stop, the frame 53--54-60 will be actuated and the lock released.

From the foregoing description it will be understood that the frame comprising the cross bars 38 and 47 and side arms 44 constitutes a variably movable controlling device or arresting frame which determines the columnar field at which the carriage shall be arrested; that the extent of variable movement of this frame is determined by the individually operable column selecting keys carrying the contact devices 43; that this frame cooperating with the fixed stop 52 is normally interposed in the path of the actuating means for the stops and locks the stops and the carriage releasing` means ont of operation; that when said frame is moved upwardly by the actuation of a column selecting key, then the means by which the stops are actuated and a release of the carriage is effected, are automatically released or unlocked so that they are free to be actuated when a denominational key is depressed; that the locking frame comprising the cross bar 53, side arms 54and arms G0 is controlled by a movement of the carriage to automatically effect a release of the locking frame from the engaged column selecting lever 31; that the construction is such that this locking frame may, at will, be rendered inoperative to automatically release the locking frame from engagement with the column selecting levers; that the construction is such that an actuation of one column selecting key is effective, to automatically release the locking frame to disengage it from a previously locked column selecting lever; that both the keys 2G and 27 have a uniform extent of movement notwithstanding t-he fact that variably movable parts are controlled thereby: that when a denominational stop is arrested by the arresting frame the key actuated lever 7 8 continues its movement independently thereof; that each lever 7 8 and its companion part 82 constitute a two-part key actuated member or lever for actuating a denominational stop 83 and that there is a spring S9 which causes both parts of said member to move together and affords a movement of the part 7 8 independently of the part 82 when the latter is arrested by the arresting frame. It will also be seen that I have provided comparatively simple and efficient means whereby the mechanism may be used either as a column selecting mechanism, in which event the decimal key is depressed after the column select-ing key has been operated, or the carriage may be arrested at any desired denominational position Within any selected columnar field after a single run of the carriage. Moreover, it will be seen that the carria'ge Will also be arrested after a single run at the desired columnar field when the mechanism is used merely asia column selector.

`What I claim as new and desire to secure by Letters Patent, is

In a typevvriting machine, the combinat-ion of a carriage, column selecting mechanisnnkeys therefor, denominational selecting mechanism including key actuated levers, carriage releasing means, and automatically operating mechanism intermediate said key actuated levers and the carriage releasing` means to render the carriage releasing means inoperative until an actuation of a column selecting key has beeneffected.
