WILLIAM H. Bossi-IKE, or NEW YORK, N. Y., AssIGNon To SONORA PHONOGRAPH co.,

l vA CORPORATION OF NEW YORK 'i rrIoNOGRAPII.

a citizenof the `United States of America,

residing in New'York, infthe' borough'of Brookl ,county of Kings, and State f New Yydi'k, have' invented certain new and useful Improvements infPhonographs, of

. which the following is aspecification.

`This ,invention relates to an improved phonogra h of that,` type inwhich no sep.a' rate liornpisl used, but in whichlthe same 1s arranged in the case in which the actuating .motor f orlthe record-carrying turn-table is arranged,

tus obpctionable for the reason that it lrenders t -dispensing with the separate horn and its supporting stand, ythe entire apparatus becomes handier, `more conveniently transportquired ifor use.

. able, and more easily storable when not re- In view of the 'foregoing,'the invention consists of a` phonographic apparatus 4in which the horn isvarranged 1n the casing of the. apparatusv and operated'in connection witha record placed on the rotating disk or turn-table by means of a stationary tube and a slidable sound-conveying tube which telescopes with said stationary tube. Thel telescoping tube'is provided'with a tube carrying the diaphragm-case, said tube bein connected byy a universal joint with the ront-end of the telescoping tube. The motor which rotates the turn-table moves simultaneously the telescoping tube, diaphragm-chamber and stylus or needle so as to remove any strain on the latter. rl`he invention consists further of the combination of the tube carrying the diaphragm-case by a flexible Joint with the telescoping sound-transmitting tube, and a sound-retaining web or sleeve, so that the needle moves 1n the rooves of the record with great facility an reduced friction. y'

The invention consists further in .a stopping deviceV by which the turn-table is automaticallysto ped when the needle arrives at the end o` a record; and the invention consists lastly of certain details of construc- Specification of Letters Patent.

Similar. letters of reference indicate corresponding p'arts throughout thev different figures ofthe drawings. y

Referring to the drawings, C vrepresents the casing o'f my improved phonographic apparatus. The casing, C is made of Oblong shape and of a suficientsize to permit the placing in the same'of the sound-delivering horn H and the spring-motor M by which the record-'carrying disk or turn-table, as well as the telescoping sound-transmitting tube, is actuated. hinged lid()1 to the under-side `of which the spring-motor M is applied. -Any approved construction of spring-motor can be used, preferably motors of that kind which are em- The case C is provided with aployed in the larger sizes of the well-, known Swiss music-boxes. The lmotor is wound up from time to time by means of a shaft C2 to which a crank-handle C3 is applied. The spring-motor M drives by a gear-wheel transmission m, m1 the center-shaft s of the disk or turn-table T on which the disk-shaped phonographic record R is placed inthe usual manner.' From the shaft s of the turn-table T.rotary motion is transmitted by a pulley p and belt p1 located at the under-side of the j lid C1 to a pulley p2 on a screw-spindle s1 which issupported in suitable bearings at the under-side of the lid C1, said yscrew-spindle driving,` by means of a semi-circular screwnut d2 located at the lower end of an arm d1 which is attached at its upper end to a Soundtransmitting tube D, the-latter' in s idewise direction, so that the same telescopes into a stationary -tube E. The tube E passes by a downwardly -bent portion E1 through an opening in the lidv C1 to the interior of the case C and connects there with the vertical portion or trunk H1 of the speaking tube or horn H, which extends from the rear-wall of the case C toward the front-wall, and which is lprovided at its front-end with 'a suitable Iwall of the case. It is supported in stationary manner in the case and is preferably made'of wood, so that the sounds transmitted from the record are clearly transmittedA to the listeners.

The telescoping sound-transmitting' tube D is made of angular shape, one end being guided in the upper portion of the stationary tube E and provided with a packing e, of felt or other material, at its rear-end so as to .slide easily and noiselessly in forward and backward direction in\the tube E. The telescoping tube D is supported on a stationary guide-rod d3 which is supported at one end in a bearing of the stationary tube E and at v'the opposite end'on an upright arm Z4 at-l tached to the lid C1. The guide-rod Z3 passes through a bearing of the telescoping tube Dl at its angular bend, as shown clearly in the dierent figures: The end of the tube E is also supported by astationary standard e3 on .the lid C1, The front-end of the'a-ngular telescoping tube D carries by means of a universal joint f the rear-end of a short angular tube F to the front-end of which the diaphragm-box G is applied. The diaphragmbox carries the diaphragm and the holder for the stylus or needle n by which the soundwaves embodied in the grooves of the phonographic record are transmitted for reproducl tion 4by the' diaphragm. The diaphragm-box G with its needle-holder is made in any approved manner. The universal joint f betweenv the telescoping tube and the angular tube F is shown in Fig. 6 and in detail in Figs. 3 and 3, and serves to impart to the connection between the two tubes F and D the required degree of liexibility.I The frontend of the telescoping tube D is connected by a fixed diametrical pivot-pin f1, which passes through slots o of the tube F, .with a ring f2 which carries by a second diametrical pivot- .pin f3y located .at right vangles to the pivotpin f1, a second ring f4 that is connected with the rear-end of the tube F of the diaphragmbox G, so that both are permittedto move: freely on .the front-end of the telescoping` tube D without. exerting any injuriousstrains.

by the needle or stylus u on the grooves of the phonographic record.

As'the telescoping tube D is moved by its f driving. mechanism laterally into the sta tionary tube E,`the flexible connection f impartsv the required freedom of motion to needle the movement to the telescoping tube,

75 the diaphragm-box and needle,'but notthe by whichthe rapid wearing ofthe needle A as well as of the record is'prevented. By the independent driving of the telescoping tube, the record is relieved from driving it, so-that but little .wear is produced on the record and the needle. Adjacent to the universal joint f is arranged a ring-shaped web or Vsleeve f, which is held inposition by an extension-tube f7 atits outer circumference and which encircles by its inner circumfer-I ence the inner end of the tube F'l so. as to prevent theI s'ounds from escaping at the iexi'ble connection between the tubes D and F; lin other words, making the connection sound-proof. The' f iexible connection be-- tween the tubes D and F also permits the lifting of the needle for introducing it into as Well as for removing it from thel record whenstarting or interrupting the piece of music represented on the record.

When it is desired to exchange the records,

the't'elescoping tube D, with the tube F, diaphragm-box G .and needle n, is lifted on its guide-rod d3 into backwardly inclined f' position," so that the turn-table is entirely free and permits the easy removal of one4` record from and the placing of a new record on the saine. Simultaneously with the lifting up ofthe telescoping tube, the segmental nut 'd2 is removed from the driving screw- 'spindle, and thereby the telescoping motion of the tube interrupted..

When the tune represented by the record is played, themotion of the turn-table is automatically interrupted by astop device,`

which is shown in detail in Figs. 8 and),

and whichconsists jof arbrake-shoe that is `pressed against the circumference of the turn-table by means ofA a vfulcrumed and spring-actuated leverl 1. VAdjacent to the rear-end of the lever 1 is fulcrumed to the supporting vpost or standard e3 of the tube E, an elbowlever2 the lower arm ofwhich passesunder the spring-actuated stop-lever 1 and engages the latter by a shoulder 3.

abuts againstthe upper armof the elbowlever 2 when the tube D arrives at the end Y turn-table and arrests the motion of the same. When the turn-table is to be ro- .A ixed'stop 4 on the ltelescoping tube D' l linstantly pressed on the circumference of the eases?" tated the lever l ofthe stop device is moved against the tension of its spring until it. 1s arrested by the shoulder on the lower arm of the elbow-lever 2. A flat spring 5 acts on the underside of the lower arm of the elbow-lever 2 so as to hold the-same in contact with the stop-lever 1. When the telescoping tube D arrives at the end of its telescoping motion after the tune embodying the record has been played, the elbow-lever of the stop-lever is. engaged by the' stop on the telescoping tube and thereby the stop-lever released and the brake-shoe i applied to the turn-table and the motion of the latter arrested.

On the left-hand side of the case are located pockets 7c for different sizes of needles. These pockets are shown in Figs. l and 2.` On the right-hand side of the lcase is ar ranged the button b by which the motor is started.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
