vo all whom 'it may concern:

Be it lrnown that I, Janes H. MOUNT, a citizen of the United States, residing in Jamesburg, in the State oNew Jersey, have invented a new and useful Improvement in Talliinghlachincsg and I do hereby declare that the following is a full, clear, and exact description of the sante.

M v invention relates to talking machines. particularly those of the disk-record type, hut some of my improvements are also applicable. to talking;- machines of the cylindericcord t vpc.

One object of my invention is conveniently to provide for taking themachine apart and putting` it together to facilitate pacltin;r and transmutation.

Another object of my invention is to simplify. strengthen and improve the attachment of the st vlus to the diaphragm holder.

Another object of my invention is to provide for conveying the vibrations through the sound box trom both sides of the diaphragm so that the sound will be amplified and made more pt'nvcrful and more distinct.

Another object of my invention is to provide for conveying the vibrations from opposite sides of the diaphragm through concentric tubes so that the vibrations from the front ot the diaphragm will so merge with the vibrations from the haclt of the diaphragm as to produce a large volume of toncof great distinctness,power and melody.

Another object of my invention is convenientlyv to provide for removing the sound hox iront the record for replacing the needle or substituting the record.

Another object of my invention is so to .rmniterhalancc the sound box and accom modale its motion over the record that the grinding noise peculiar to most talking machines will he further obviated.

Another object of my invention is so to support the sound box on the cabinet that the whole machine can be jarred or moved without. disturbing the sound or scratching the record.

Other objects of my invention will be set forth hereafter in the description.

To these various ends, my invention coinprises various novel features of construction and combination of parts as' are hereinafter pointed out 1n the claims.

In order that 1n invention maybe fllly' understood, I sha 1, prior to claiming the same, describe in detail a talking machine ing drawingsdorniing part of this specili- 'cat'ion in whichiilre numbers indicate corresponding `parts in all the ligurcs.

Figure l isa perspective view of a talkin;Y machine of the disl-z-recortl t pe c1r.l;o. lyiiig my invention, a part lag-ing il section. l 2 is a side elevation ot' the same. Fie'. is a plan view of the same. Fig -l is an cnlargeti side. elevation of the same, -irts heing in section and the cabinet. ieino\etl.- Fig. 5 is a detail view showing the sound box and stylus in full lines swung aside for replacing the stylus and, in dotted lins, raised for introducing the record. Fig. t'- is an end view of the sound box showing the stylus resting on the record. Fig. Tis a similar view showing the stylus and sound box partly raised for introducingv the record. Fig. 8 is a similar View showing the sound KSO box and stvlus fully raised for replacing `he needle. Fig. 9 is an end view of the sound box and attachments with its cover removed so as to disclose its interior. Fig. l) is a sectional view of the sound box and attachA ments. Fig. 1l is a detail view showing he i diaphragm and attachments removed from the sound box. Fig. l2 is an enlarged detail view showing the stylus clamp and its attachxneuts to the diaphragm holder. Fig. 13 is a detail view showing the method of supporting the diaphragm holder in the sound box. Fig. M is an end elevation or the cabinet showing the device for adjusting the inclinathan of theA record and the means for opening the cabinet without removing the winding handle.

In the drawing, 10 designates the cabinet- O a talking machine which containsl the mechanism, 11, indicated in dotted lines .in Fig. 2 for rotating the turntable, l2, and thereby rotating the record, 13, which is here represented as of the ordinary disk-type.

14 designates the'windin" .ian-:ileof the actuating mechanism, 11, which prefer to fasten permanently to the winding shaft, l5 and arrange to dropinto and he raised out o a curved slot, 16, shown in Fig. ,14, in the end wall of the cabinet, t0, so that the nicchanism, 11, being fastened to the cocer, 17, of the cabinet, 10, when said covris raised on its hinge, t8, convenient access may be had to the actuating mechanism without remov- 1ing the winclnghaned.-

.Ww im www How In order that the timing device, 19, on the top of the cabinet and the starting and stopping derice, 20, also on the top of the cabinet, may be nmnipulated by both hands sir'rnultanmusly, l arrange the timing device as )shown in Fig. l on the right hand side of the cabinet and the stopping and starting device, 20, on the left hamtsidc of thc cabinet, connecting the stopping and starting ,0 device by suitable gea ringr with the actuating mechanism, l1, as .indicated in Fig. 2.

The stylus and sound box in my invention is arranged as hereinafter described to travel radially from the periphery of the 35 record, 13, to the center of the same and in order to aid said motion produced by the pressure of the side o the record groove against the stylus, I provide means for raising the outside end of the cabinet. and there- `2Q by inclining the record downward in the direction of travel of the stylus so that the motion of the. stylus toward the center of the record will be aided by gravity, the pressure of the side of the groove against the stylus will be minimized and the grinding noise thereby produced peculiar to most, talking machines will be entirely obviated. As con- Yenient means for thus raising the outer end of the cabinet., I have here shown brackets,

21, attached to the end of the cabinet and carrying threaded nuts, 22,'through which are screwed correspondingly threaded legs or standards, 23, having heads, 24, by which they may be turned to elevate that end ot' Si Ythe cabinet and therefore incline the record as much as may be desirable. The .'tylus, 25, is inserted in the clamp, 26, in the usual way and such clamp is connected to the diaphragm, :27, by a sound conveying bar, 2S,

40 of the ordinary description. I attach the stylus clamp, 2G, however, to the diaphragm ring, 29, by means of a thin spring plate, 3o, secured in the plane of the diaphragm to a plate, 31, rigidly attached to the ring, 2t).

so that.the stylus and its clamp can play with the vvibrations imparted to it through the bar, :28, by the diaphragm, 2T, on su-id spring plate, 3U, to and fro in the direction of the axis of thc. diaphragm but not transversely to said axis. By this arrangement, the Vibrations of the stylus are more accu rately transmitted to the diaphragm, 27, and a perfect reproduction of the original sound is made.

vThe sound box, 3Q, consists of a closed head, 33, haring a handle, 34, and a cylindrical wall, S5, formed integrally with the head, On the inside of the wall, 35, of

the sound box are. tixed blocks. 3G, hau-'ing' axially slotted seats, 3T, opening inwardly to receive cushioned studs, 3S, projecting radially from the periphery of the diaphragm ring, 29, so that when the diaphragm ring is in place, the diaphragm and its ring will be separated by an air space from the head,v

33, ofthe sound box, and also from the wall, 35, of said Sound box, as best indicated in Fig. l0. Thewall, 35, of thc `:ound box is joined detacluibly to an annular ring, 39. secured to the outer end of a tube. 4t). which is 7g covered with cloth or other non\'ibrator)v material, 41, as best indicated in Fig. lt).

The detachable union of the sound box to the ring, 39, preferably consists of the inturned flange, 42, on the/ring, 39. to receive 75 the end of the wall, 35, which has lugs, 43, to pass through the slot', 44. in said tlangc, 4'2, so that the sound box can be discngagcd from the ring,` 39,' by rotatin, r it so as to bring one lug, 43, opposite the slot. 4l. whcn so the sound box can be easily removed To malte the attachment of the sound box to the ring` 39, and tube, 40, more secure, I fasten a bracket, 45. on thc ring, 3), carrying a nut, 4U, through which a ser screw. 4T. 85 is arranged to screw against the wall. 35. lvith this arrangement, by detachingr thc sound box. tl from the ring, 3E), (Inx dinphragm ring, 2t). and with it the diaphragm and stylus can bc removed from thc open side of the sound box, the stylus and its clamp heilig withdrawn through a slot, 4S. in the wall of the sound box. lVithin the tube, 4t), I fasten concentric-ally so as to leave an air space' between them, an inner 95 tube, 4S), by radial spacing pieces, 5t), so that the axis of the tube, 49. will be directly in line with the diaphragm, 27. Around the inner end ot` the tube, 49, l preferably the end of which is arranged to abut the collar, formed around an annular tlangc.

53, projecting inwardly from the diaphragm ring, 2t). Bv this construction. as will be best seen in ltig. lt), the vibrations from the front of the diaphragm, 2T, will bc transmitted liirectly through the collar. 52. and

the inner tixbc, 49, while the vibrations from the rear of the diaphragm, 2, will bc transmitted through the space between said diaphragm and hcad of the sound box. through the annular space bctwcen the ring.".2l. and

thc wall, ,of said sound box, through thc space between the flange, 53, and thc annular ring, 39, and thereby through thc annu- 11' lar space between the tube, 40, :tr-.l the Vconcentric inner tube. 49. tixed therein:

. On the top of the cabinet. l0, l tix a rcrtical socket, 54. provided with a sct sci-cw,

55. in which is clamped detachablxj a .standard, 5G, fixed on an outer sound tube, 5T. The sound tube, 5T, is provided with a cylindrical extension, 5S, axially in line with the dia lnagm. 27, and sound tubes. 40 and 4i),

am in this extension. of the sound tube, 5i', the tube,40. is arranged to travel axially, carrying with it the sound box and st vtus,

by means of a roller, 7?, fastened to the cud of the tube, 40, and runningr on thc interior of the sound tube, Within the sound place a. non-vibratory bushing, :'11, against 100 tube. 5i' and 58, is also lixed concentrieally an inner sound tube, .59, by radial spacing pieces, 60, and in said 'inner tube, 59, the inner tube, 49, is likewise adapted to travel 5 axially and freelv, supported by the suine.

roller, T3. The direct, and reflected vibrations from the diaphragm, 2T, will therefore `be conveyed through the sound tubes, 59 and 58 respectively in all positions of the 1Q sound box es the seme travels over the record, 13.

n the outer end or' the outer sound tube,

5?, is fastened by Ineams of an ordinary1 bny cnet loci'` an amplifying horn, (ll, and on the outer end of the inner sound tube, 59, is

fastened by means of :in ordinary bayonet l .35, concentricallv within the outer horn, 6i, but projecting `vond the suine, an inner amplifying horn, (SQ. The direct vibrations from the diaphragm, 2T, will therefore emerge 'onx the inneil horn, (32. und the reflected vibrations from thediaphrngzn. 27. i

will emerge from the outer horn. (il. The adjfusttneut and arrangement ofthe two v horns is auch that the Sounds emerging therefrom will mingle so ns to produce :1

melotiour,v whole of peculiarly cler, distinct...

:ind amplified character.

To guide and support the sound box and the inner ends of the cylinder. 40. :1nd inner tube, 49, while traveling radially across the f record and :it the saine time permit the sound 'y box to be rinsed from the record for replacing the record on the stylus, l fasten a mil,

63, on top of the cabinet parallel with the axis of the motion 'of the sound box. (lne end of the ruil, 63. 1s fastened detaicbnbly in n bracket, Fri. attached to the end of the outer sound tube. 5u, :ind the other end of 40 the rnil. 63S, is fastened detnclnxbly b v means of a Set screw, (35, in n slotted standard. im. erected on the top of the cabinet, 10.' The rail, 63, is formed with an upwardly curved flange, (S7, running alongr its npywand inner 15 side. 0n theeide of the sound box` 32, is

secured a short axle, (i8, on which is mounted to rotate freely an antxtriction roller` (Si), having n concave foce, 70, to run on the rail.

63. nn annular grr-ove, 7l. to engage :intl run on the tinnge, 6T and un annular hhonlder,

roller, G9. runs along the rail, 63, and the groove, 71, on the flange, 6T, :is best shown 1n Fig. t3, so tlnit the `sound box and its itttnclnnents, while traveling across the record is supported by the stylus, 25, the rail, 63,

5 sind the roller. T3. A lar e part of the weight 'of the sound tube an attachments is therefore taken oli the stylus which bears jupon thereeord with inst sufficient. weight to reueivejlie vibrations thereof and the grinding noise peculiar to most talking machines lil), and the lionlder. T2. i rwtcd on the flange, iii', :is shown in Fig. T. The ntvlne is thus held above the record so that. the sinne can be removed and replaced ut will. On the simil, ('18. of thc roller, liti, is iixeil o hook, T, curving around the under side ot' the ruil, G3, which keeps the roller. tit). from heimT thrown ott the ruil, (23, ne indicated in Figs. t, Tand 8. When it is desired to replace the stylus. the sound box is raised still farther above the record. :is indicated in Fig. 5. nntil the Umore. 131, and shoulder, T:3. :tre .li:-.engnged from thc. thingie, (37. :1nd the hook, T4, engages the ruil. (S3, und. snp'iort the sound box in its uppermost position. n\ indicated in Vig. o. 'lne stylus may then he removed and replvcell :it will. Conversely to replace. the .stylus on thc record, the mind box is .swung over on thc record until the roller. (i9 and groove. 7l, engage the ruil. (El. :1nd lionne. (S7. :is previously described :ind shown in l`ig. t3.

B v the arrangement thus dei. ribed. the sound tubes und horns firmly secured to the cabinet und the found box und attachments securely confined within their limit of motion, so that the whole machine cnn he jul-red or moved without diftnrbing its,v zic tion und without Scratching the record even when the stylus is shifted across its fnac.

lt is evident ihnt the concentric lmond tubes :and horns herein described muy also be applied to the ordinary phonograph in which the stylus swings on :i pivoted elbow. but l prefer the axial motion of the dinphrngni with reune-ct to the sound tubes .is giving n very much clearer und better production of thc sonnth iinpresfed on the record.

lt is eviflfm lmt thc reproducing ineclmninni herein described muy be need with n cylinder record as well :is wi*h the disk record shown. lt is also evident that :i coinrnon `Qpirit level may be employed on top of the cabinet to. show the inclination of the cnbine't and thun of the record when the saine is adjusted as herein described to cause the motion of the stylus to be aided by gravity.

Having thun described my invention und the mode in which l curry the sinne into practice. l claim as new und desire to secure by Letters Patent.
