T 0 all whom it may concern:
Be it known that I, 'lnonas Kaamrna, a citizen of the United States, residing at Philadelphia, in the county of Philadelpl'iia and State of Pennsylvania, have invented certain new and useful Improvements in Talking-Machines, of which the following is a specification.
This invention relates to talkin machines and is directed to the provision ot a machine of an improved construction in which the relative movement of the sound-record and the reproducing mechanism necessary to permit. the stylus of the reproducing mechanism to track in the record-groove throughoutthe several convolutions thereof is affected by moving the sound-record and the turnt.ahle on-which it is supported bodily in the plane in which they lie.
In accordance with my invention, a. turntable is. provided for supporting a disk record and this is so mounted as to permit of rectilinear movement thereof in the plane in .which itlies. A motor mechanism is emploved for rotating the turntable on its axis an this motor mechanism may also be arranged to cll'cct the lateral movement of the turntable. The reproducing mechanism is stationarily mounted with respect to the turntable so far as concerns movement of that mechanism radially of the turntable;
if desired the reproducing mechanism may be so mounted as to permit of movement transverse to the plane of the turntable so that the stylus thcreol may track faithfully in the record-groove and may be moved to an inoperative position while changing records.
The devices whereby the motor mechanism, in addition to rotating the turntable, efi'ects the rectilinear movement thereof, are so constructed as to move the turntable bodilyas it is rotated at. the speed necessary to enable the stylus of the reproducing mechanism to follow the ret-m'd-groove properly. For this purpose the motor mechanism may be arranged to move with the turntable if desired, but I prefer to mount the motor mechanism stationarily and connect it to the turntable by devices which will permitof theneccssary relative movement of these two parts while maintaining the PpBlut-lVC Specification of lettrs 'latent.

connection between them, as for instance, a. telescoping shaft or a spline.
The preferred embod1ment of my invention is illustrated in the accompanying drawings in which- Figure l is a top view of a talking machine, broken away and sectioned in part, Fig. 2 is a. sectional elevation of the same, the section being on line 22 of Fig. 1, and Figs. 3 and 4 are detail views in section on lines 33 and 4-4 of Fig. 1.
Referring to these drawings, 1 indicates the motor-box of a talking machine having a frame 2 secured to the under side of the cover thereof. side of this frame are supports 3 in which the ends of 2 rods 4, 4: are secured, these rods beingparallcl to each other and located adjacent to opposite edges of the frame 2. To the under side of frame 2 is secured a motor mechanism of any suitable construction, but preferably a. spring-motor 5 of the type commonly employed for driving the turntables of talking machines. This motor mechanism drives a gear 6 which meshes with a pinion T secured upon a shaft 8 which is mounted for rotation in bearings formed in standards 9 depending from the frameQ. One of the standards .1 has a bearing formed therein for a rewinding shaft 10 by which the spring of the motor 5 is wound u the end of this shaft 10 being adapted to ac engaged by a winding handle 11 of the usual construction. The shaft 8 has a. groove 12 cut therein and extending lengthwise thereof.
A movable frame 13 has sleeves 14 of substantial length at opposite ends thereof through which the rods 4, 4t extend, and this frame carries the rotatable turntable of the nun-thine. Referring to Fig. 3, it will be seen that frame 13 has two depending arms 15 integral therewith provided with openings through which the shaft 8 extends, and a bevel-gear It; lies between these two arms 15 and 1s splined on shaft 8 by means of a key entering the groove 12. One of the arms to and the body portion of frame 13 have bearings formed therein fora vertitally-disposed shaft 17 which extends 11 wardly through a slot lathe cover of t e motor-box 1 and has the turntable 18 of the Vilma 21 shag and 31'' which I? iii-551a isms:
eeenee the two handles 51 end 52 together to the left, thereby sliding the frame 13 along on the rods 4, ibeck to its initial position. Then onreleesing the handles, the half-nut 47 will be drewn "into engagement with the feed-screw 48 by spring 53, thereby moving the handle 51 relatively to the handle 52 to the position shown in fig. 1 end the parts are in reediness for another reproduction. By turning the handle 38 either at the conclusion of the first reproduction or after the parts have been brought beck to initial po' sition, the motor may be stopped by the engement of the brake-pods with the colfifr end by adjusting handle 38 between its extreme positions any speed of rotation of the turntable desired may be obtained.
Having now described m invention, whet I oleirn as new therein so desire to secure by Letters Patent is esfollows:
A talking-machine comprising a motorbox a. pair of rods secured to the under side of the cover thereof, e frame slidable on said rods, :1 motor secured to the under side of seid cover, two members splined together and roteteble on e horizontxil axis, one or said members being secured to the under side of said cover and driven by seid motor and the other of seid members being mounted upon said frame, a. feed-screw mounted for rotation on the under side of seid cover, means ectueted by the motor tor roteti the feed-screw, a shaft mounted on sai frame and rotatable about a, verticel axis, intermeshin geers cerried by said shaft end said mom r mounted upon the frame, a turn-table for e talking-machine record mounted u on said shaft above the cover of the motor- K, s half-nut pivotelly mounted on seid slideble frame, on o ereting lever pivotnlly mounted on said s iduble frame and arranged to move said half-nut into and out of engagement with said feed-screw, and reproducing mechanism held against lateral movement and adapted to coact with 3. record on seid turn-table, substantially as set forth.
This specification signed and witnessed this 28th day of July, 1908.
