BRAKE FOR TALKING-MACHINES AND THE LIKE.

Specification of Letters Patent.

Patented Nov. 1%, 1916.

Application filed January 25, 1916. Serial No. 74,086.

. To all whom it may concern 7 useful Improvements in Brakes for Talking-- Machines and the like, of which the folldwing is a description.

This invention relates to brakes for talking machines, phonographs, graphophones and like apparatus and is particularly directed to brakes comprising a braking mem ber adapted to arrest the turn table by cooperation with suitable means whereby said braking member is brought into braking position when the swinging tone arm is in a predetermined position. Preferably such cooperating means includes means whereby the swinging tone arm is supported when in such predetermined position.

Other features and objects of the invention will be more fully understood from the following description in which- Figure 1 is a top plan view showing one form of my invention; and Fig. 2 is a detail vertical sectional elevation of Fig. 1.

Referring to the drawings, the base '1 is of any approved construction. The turn table 2 is shown supported on a preferably central shaft and may be driven by clock work mechanism or other type of motor. The swinging tone arm 3 carrying the reproducer a is shown mounted on the standard 5 fixed to and projecting .upwardly from the base 1. It will be noted that the record is placed upon the turn table 2 and the stylus of the reproducer 4 brought in suitable relation to the record to effect the desired reproduction.

The braking member is shown comprising the forward or braking arm 6 carrying the friction pad 7 and further comprising the rearward arm 8, the latter being preferably in fixed relation to said forward arm 6. The braking member 6, 8 as a whole is shown pivoted onto the stud 9 extending through the opening 10 within the upper plate of base 1. Such pivotal mounting means for .the braking member secures reciprocatory movement of the braking member.

The rearward arm 8 is provided with the hook 11, and the projection 12, shown extending downwardly from in fixed relation to the swinging tone arm 3, cooperates with said hook 11 whereby the braking member is moved into braking position when the swinging tone arm 3 is moved into off position. The resilient member 13, shown as a flat spring, normally tends to turn the stud 9 in the direction to move the braking member into non-braking position. The resilient member 13 is shown having its end 14 abutthe inner wall of the base 1, and havin g its free end 15 extending through a slot inthe stud-9. If desired the end 14 of resilient member ,13 may be the pocket 16.

The rearward arm 8 of the braking member is preferably provided with the stop portion 17 adapted to engage a lower portion 18 of the base of the standard 5, under action of the resilient member 13 when the swinging tone arm 3 is in playing position. Prefer: ably, the projection 12 supports the swinging tone arm when in off or non-playing position, and to this end, the step 19 is provided, whereby the moving tone arm isheld in somewhat elevated position. The step 19 is shown as an extension projecting laterally at the base ofthe standard 5, and may be provided with the inclined surface 20 to secured within guide the projection into proper position onto the step 19 when the swinging tone possible-the protruding parts on the top of the base 1. The resilient member 13 may constitute the sole resilient portion of the braking arrangement, although, if desired,

forward arm 6 and rearward arm 8, may also be constructed of resilient material,

such as stamped metal. 1

Whereas I have illustrated my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of my invention.

What I claim and desire to secure by Letters Patent is 1. The combination with a rotatable table and a swinging arm, of mounting means for said swinging arm, a brake lever having one end adapted to engage said rotatable table, an extension carried by said swinging arm and adapted to engage said brake lever when the said swinging arm is. in a predetermined position to thereby effect engagement of said one end'of the lever with said rotatable table and means for supporting said extenthe braking member and particularly the sion and said swinging arm when said swinging arm is in said predetermined positio 2. The combination with a base, of a rotatable table carried thereby, a swinging arm, means for mounting said swinging arm on said base, a brake lever mounted on said base, one end of said brake lever beingadapted to engage said rotatable table, means carried. by said swinging arm for engaging said brake lever when said swinging arm is in a predetermined position to thereby eflect engagement of said one end of the lever'with said rotatable table, said means comprising a member extending from said swinging arm toward said base and a support positioned on said base to support said extension and therewith said swin ng said swinging arm is in a predetermined position to thereby eiiect engagement of -the said one end of the lever with said rotatable table, and a support positioned on s id base to support said extension and therewith said swinging arm when the said swinging arm is moved to said predetermined position.

- 4. The combination with a base, of a rotatable table carried thereby, a swinging arm, means for mounting said swinging arm onto said base, a braking member having a bent portion, a friction pad carried by said bent portion and adapted to arrest said stable when said braking member is in braking position, oscillating mounting means for said braking member, a hook carried by said braking member, a pro3ect1on extending from said swinging tone arm and adapted to engage said hook to move said braking member into braking position when said tone arm is in off position and means coope -ating with said projection to support said arm when in off position.

In testimony whereof I have signed this specification.

WILLIAM F. sienna.
