l ln all ofthe devices iam aware of when the `reproducer or stylus nates preferably in a rubber tip 19. `The rod 18 is adapted to lit tightly in the rod 7L and the split crimped end 17 adds to the resistance of moving the same. Upon each side of the opening 14 upon the bar i are graduations marked to indicate particular convolu` 'of thischaracter that I run ed the record it is allowed to run proper distance so when the st lus or repro-' some distance further, which occasions a pe- .riod of time in which Vobjectional scrap1 ng noises are made, and the urpose of the m- ;,ventionis to avoid this an stopthe turn-ta- ,ble immediately u on the termination of the.

record'. As is wel known, some records are necessarily of a few revolutions lon er than others, but the maximum distance etween theextremes is not perhaps more than twenty revolutions.- l have, therefore, in the draw- .ings shown the device to'be Vadjusted but a comparatively short distance-radially; the point of lthe stylus or reproducer is shown with its path in Fig. 1-, and the turn-table is therefore represented as going towards the stylus.

The figures` represent the turn-table B as moving and therefore the brake 25` is away therefrom and the rod 18 has its ointer 13 set to the gradation or revolution o the turntable marked upon the bari at which the record terminates-and at which it is wished the same to be stopped, and consequently the end ofthe rod 18 projects from the rod h the ducer reaches the point desire it will strike the end 19 and force the rod h inward against the pressure of the spring8, and turn the le' f .ver g in the direction of its arrow and awa from the lever 8, which being unlatched a lows the spring 32 to operate and force the stud 28 against the cam 29 of thelever c-and en it, as shown in dotted lines in Fig. 4, in t edirection of its arrow, and then bring the foot piece 25 against the edge of the turntableand stop its motion.

lt will be readily seen that the main features are an adjustable means capable of being placed in the path of the stylus at the ending of a record, whether it consist of few or many revolutions, combined with a brake device whereby the 'rotating 'turn-table is brought to a stop.l

l claim as my invention s 1. The combination in a sound-reproducmg machine of a turn-table, a disk record and a spring-projected brake, with a tripping device, and a re roducer or stylus, means for holding the bra re retracted and for releasing the same to engao'e the turn-table, consistiiw of a lever adapted to lock with the brake and with the tripping device, the said device provided with an adjustable tip whereby the brake may be operated at any revolution of the turn-table.

A 2. The combination in a sound-reproducin machine of a re roducer or stylus a turntable, a disk recor a brake adjacent to the turn-table, means for holding the brake retracted from the turn-table and for releasing the same, 'consisting of a mam lever one end of which engages thebrakelever a trip )ing device engaged by said main lever an an adjustable member adapted to be interposed in the ath of. the moving stylus.

' 3. he combination in a sound-reproducin machine of a re roducer or stylus a turnta le, a disk recor a brake adjacent tothe turn-table, means for holding the brake retracted from the turn-table and for releasing the same at any revolution thereof, consistying of a main lever one end of which enga es thebrake lever a tri ping device engaged y said main lever an an adjustable member adapted to be interposed in the path of the moving stylus.

4. Ttlie combination in a sound-reproduclng. machine of a reproducer or stylus a turn-table, 'a disk record, a brake adjacent to 'the' turn-table provided with a locking and disengaging lever and a spring -operated foot-piece, means for holding the brake retracted from the turn-table and for releasing the same at an revolution thereof, consisting 'of a suitab y supported main lever one end of which engages the brake lever, a tripping device engaged by said main lever` and an adjustable member adapted to be interposed in the path of the moving stylus.

5. The combination in a sound-reproducing machine of a reproducer or stlyus a .turn-table, a disk record, a brake adjacent to the turn-table, means'for holding the brake. retracted from the turn-table and for releasing the same, consisting of a lever extending over the face of the turn-table, one end of' which is adapted to lock the brake, a-triping device engaging the opposite end of said ever, having an adjustable member adapted to be interposed in the path of the moving stylus, 'and a graduated scale for adjusting the member.

6. The combination in a sound-reproducmachine of a re roducer or stylus a turnta le, a disk recor a brake adjacent to the turn-table having a spring-impelled footpiece adapted to be retracted from the turntable by acam-lever, means for holding the cam-lever in a retracted position and for releasing the same, consisting of a suitably sulpported and plvo ted lever extending over t ie face of the turn-table, onel end of which engages the cam`1ever,a tri ping device engag-y ing the opposite end of tie said lever having an adjustable member'adapted to be set byv means, of a graduated'soale adjacent thereto,

' at a determined position', to permit the moving stylus or reproducer to engage the same at any p redeterminedfrevolution of the turntable.
