TALKING-MACHINE.

Specification of Letters Patent.

Application tiled July 15. 1807. Serial No. 383.804-

T all whom 'it may concern:

Be, it known that l, 'IRA G. FosLER, a citizen of the United States, residing in Chicago, inthe county of Cook and State of Illinois, have invented a new and useful Improvement in Talking-Machines, of which the following is a specification.

My invention relates to improvements lin talkinganachines.

In the practical operation of talking-machines, considerable ditliculty and annoyance has heretofore been experienced from the fact that the machine continues to run after the sound reproductionon the record has been completed, the overrunning of the record as it is called, not only producing a disagreeable noise but also tending to wear away and injure the reproducing stylus.

The o bject of my invention is to provide a simple,`eilicient and durable construct-ion of talking machine which stop when the reproducing stylus reaches the end of the sound record to be reproduced,

My invention consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described by which this object or result is practically accomplished.

In the accompanying drawing `forming a part of this specification, Figure i is a front elevation of a talking machine embodying my invent-ion. Fig. 2 is a detail vertical section online 2-2 of Fig. 1. Fig. 3 is a detail elevation showing the parts in a difierent position 'lroin that illustrated in Fig. 1.'

Fig. 4 is a detail plan view partly in ,horizontal section. y

In the drawing, A represents the frame oi the machine, Il the reproducer having the customary stylus b traveling in the sound record groove c of the record C, D the rotary mandrel or holder to which the record C is secured, D1 the traveling carriage or support upon which the reproducer is mounted and I)z the feed-screw for the reproducer carriage.

'E is the stopping and starting lever having the customary brake arm. E1 engaging the brake wheel E2 lating device. All these parts may be oi' any suitable kind or construction `r customarily employed in phonographs, graphophones or other talking machines.

For convenience in the drawing, I have illustrated the. same as being ot a well known phonograph con- In order to automatically stop the machine. and further rotation of the record (l when the reproducer reaches the end ol' the .sound record groove c thereon, I connect willi the stop lever E ol the talking machine an automatically movable stop device or slide lf preferably having a slotj` to receive the upper end ot' thc stop lover E and a slotj1 to receive the guide pin or projection g on the clamp G, by which, in connection with the clamp piece g and clamp screw g2, the automatic stop device is mounted upon the frame of the machine or its inclosing box A1. The stop slide or, device F is furnished with a spring ji engaging` an integral lip f3 on the stop slide at one end, and an upwardly projecting flange g3 on the lined clamp GrA at the other end. `This spring, when the stop slide is released by the releasing trigger H, serves to automatically retract the stop slide and operate the stop lever E of the machine. The stop slide I" is further provided with a set or projection f4 which engages the toe h of the releasing trigger H, which is pivoted to the upright ilange (13 of the clamp G. The releasing trigger H is preferably not directly engaged by the traveling carriage but its upright arm h1 is furnished with an adjustable arm h2 which is so engaged by the reproducer carriage to operate the releasing trigger and release the stop slide when the reproducer carriage moves tothe right tothe required extent or until the reproducer-stylus comes to the end of the sound record groove c in the record C. The releasing trigger is provided with an adjustable arm li? so that the automatic stop device may be set to operate at diii'erent positions of the reproducer carriage as the sound record grooves cover varying y lengths oi the. record C according to the length ol' the song or piece oi music that may be recorded thereon. 'The' adjustable arm 'if is preferably of sector shape and furnished with a pivot slot h3 at its lower end and a curved slot h at its upper end having a plurality ol notches -h5 therein to engage the rivet 71. in the upper arm h1 of the releasing trigger. The at'ljustablearm is secured to the releasing trigger at its lower end by a l rivet 7:7. By simply slipping the releasing trigger slightly upward, the upper rivet 7i l will be i'ree from the notches lr, and then thc r adjustable arm can be swung to either side l into position for the upper rivet 7L to enter l another notch la; in the adjustable arm if?.

' The reproducer carriage D1 has a handle orv pin d which engages the adjustable arm h2.

I clalmz-J j 1. In a talking machine, the combination with'the rotary record holder, reproducer,

.reproducer carriage and the stop lever, of an automatic stop slide having' a setting pro jection, a spring for actuating said stop slide, a clamp 'upon which said stop slide reciprocates, are easing trigger having an adjustable arm in the path of the reproducer carm ringe to automatically stop the machine and prevent overrunning of the sound record, said releasing trigger having an upright-.arm furnished with upper and lower rivets,"'and said adjustable arm having a pivot slot at its lowerend and a curved slot at its upper end furnished with a plurality of adjusting notches adapted to engage said upper rivet, substantially as specified.

2. The automatic stop attachment for talking machines comprising .a clamp having f a movableclamp piece' and clamp screvv and y justable arm having a pivot slot and a'curved slot furnished with a plurality of adjusting notches, substantially as specified.

3. The automatic stop attachment for talking machines comprising a clamp, a stop slide mounted thereon, and having a set projection -for engagement With the releasing trigger and a slot to receive the stop lever of the talking machine, a spring connecting said stop slide and clamp and a releasing trigger mounted pivotally upon said clamp, said releasing trigger having an adjustable arm furnished With a pivot slot at its low'ver end and a curved slot at its upper end I'ovided with a 1plurality of adjusting noto es, substantial y as specified.
