5 as LOoVEW S FRANQEQI DEVICE FOR} AUTOMATICALLY s'rorrme THE Disks or .raLiziivfearicieinjsls.

To ally/1mm it my concern:

'Be it' known that I, JULss LOUVE'L, of Montrouge, Seine, France, have invented :1 Device for Automatically Stopping the Disks of Talking-Machines, of which the following is a specification.

This invent-ion relates to the automatic stopping of the disks of talking machines provided with a needle or a sapphire when the performance is finished, this stopping arrangement being applicablein cases where the disks employed bear a record beginning near the center and finishing near the circumference. \Vith this object, the recordis extended by a curved or' straight groove or embossment which causes the needle or the sapphire to move outside of the disk; the sound arm then falls on to a rod and weight actuates a brake which stops the disk. i

Figures 1 to 9 illustrate two different forms of the device employed. Fig. 1 is a plan of a talkin machine provided with the automatic stopping device. Fig. 9. is a plan of the stopping apparatus. Fig. 3 a side view of the same. Fig. 4 an end elevation. Figs. 5 to 9 illustrate a modified form of the device. Fig. 5 is a plan of a machine provided with a stopping device; Fig. 6 is a side view of the brake mechanism; Fig. 7 a

.plan of;the same; Figs. 8 and 9 being respectively an elevation and a plan of a dit ferent form of the brake.

For the purpose of insuring the automatic stopping of the apparatus, the disk abearing the record has, following the record, a curved or straight groove or embossment I); along which the needle or the sapphire. carried by the diaphragm 0 arranged on the sound. arm (I having completed its traveL.

that is to say finished the reproduction of the piece. is held by the sapphire in the last spiral of the record while the disk continues to rotate until the spring is completely relaxed.

Specification of Letters late nt'd P t t a "I Application filed March 18, 1910. Se;

*ceires: the Fso'und arnr' tl -wli-eii Etlipieceis The automatic stopping'acc di invention is etiecteda's' la'llo'ws' terminating in the form ot-a i position; ;a pedestal-7' having;

finished. the arm (I being moved outside by the disk .1, under the action of the curve I) that runs to the outer rimof the disk and along which the sapphire or the needle must move. atlthe end of the record. The sound:

arm (Z drops on to the T partof the'ro'd i and by its weight lowers that rod. This latter exercises pressure on another rod k termimifing in an angular piece which actriates a lever Z. To this levers small connecting-pod m is attached which terminates on thezone hand in a pivot and on the other hand is connected with the rod f and imparts thereto the motion for effecting stopping, similar to that which would have been imparted with the finger. The leverm' the is flexibly connected and fixed at n on a support 0 which likewise supports the lever-Z.

To one of the ends of the connectin rod a."

spring 9 is attached which is put-un er tension of a screwnq held by a support r-and insures the starting of the apparatus. The regulating of the throw of the lever l'is effectcd'by a. small screw slmounted on the lever la. y p

In the simplified device shown in Figs. 5

to 7 the brake action is effected on the outer rim of the disk-carrying table t. In these 1.5 the brake is represented as in contact with the disk carrying table. The de vice comprises a pedestal j, formed with a socket in which the rod i is engaged the upper end or head of which is in the form of a T and receives the sound arm at the required moment. The lower part Qf this rod 5 rests on a small lever u pivoting at 0 on the bins of the pedestal j. The free end of the lever 11- rests on a piece X pivoting at X and constituting the brake. .A :spring y -pushes the brake-piece X back so as to allow the free rotation of the disk-carrying table t during the performance. When the performance is finished, the curve 6 leads the sapphirc or the needle outside of the disk a, the sound arm t falls on to the T-head of the rod 1' and the brake X acts onthe-rim of the table 2, causing it to cease" rotating.

In the device as in Figs. 8 and 9, the sto carries the rod 11 as in the device described above. vThis rod 2' bears, at the required moment, on a lever 41 carrying a brake shoe 2 a rotatable disk-carrying table, a-record whichacts on the under shrface of the table t. The part of the lever-y where the brake shoe 2: is placed forms a counterweight and raises the rod i while the apparatus is in I disk carried thereby, a sound arm, and a needle. carried. by the latter, of a brake de- -vice -"comprising an arm adapted' to be brought into contact with the table, and a second arm arranged to support the sound arm when the latter has been moved laterally to cause the needle to bemoved off of the record disk, said second arm being operated by the weightof the soundv arm to effect the operation of the first arm and stop the rotation of the table and disk.

In testimony whereof I afiix my signature in presence of two witnesses. v J ULES LOlLl'VElZ. "Witnesses:
