Specification of Letters Patent.

Patented June 19, illlid.

Application filed June 25, 1915. Serial 1x? a. 35,221.

stops which can be applied to sound repro- 10 ducing and analogous machines for automatlcally setting a brake and stopping the mechanism at a predetermined time.

An object of my invention is to stop the playing of a record of a sound reproducing machine immediately when a predetermined point near the end of the sound groove is reached by the stylus or sound box.

A still further object is the production of a device of the kind stated, which can be easily attached to or detached from sound reproducing machines now in general use without alterin the general construction of the machines. @till further objects are simplicity in construction and greater eliectiveness in use than with devices heretofore designed for the purposes stated.

To these ends my invention comprises the features of construction and combination of parts which will be hereinafter more particularly described and set forth in the claims.

In the accompanying drawing forming part of this specification, Figure 1 is a plan of my invention; Fig. 2 is a section taken on the line XX, Fig. 1; Fig. 8 is a plan of a sound reproducing machine of the con ventional Edison type to which my .vention is shown applied, part of the structure of the machine being broken away to more clearly expose its mechanism; Fig. l is a plan of an alternative construction of invention, and Fig. 5 is asection taken on the line YY of Fig. 4:. p

In the drawing A indicates a support or base in'the form of an arm upon one end of which is rotatably mounted by means or shaft 2 a revoluhle spool or turning menr her B, said shaft being riveted or otherwise secured vertically upon the surface of said arm. The spool B has its body or sleeve 3 journsled upon said shaft, and its lower end l is in the form of a circular plate eccentrically disposed as regards the axis of said "spool and shaft, while its upper end or head 5, which is also circular is concentrically disposed as regards said axis. The lower end acts as a striking member, which is adapted to impinge or press against the releasing device for the brake to be hereinafter described. striking member impinges is regulated or. determined by the position assumed rotatably by the spool on its axis, it being obvious that due to the eccentricity of the striking member on its axis, the time at which the periphery of the striking member im pinges can be predetermined. To hold the spool in adjusted position on its axis a re tarding pawl 6 in the form of a spring arm is secured by a screw 7 or other suitable '70 means in fixed position, the free end of said pawl bein formed with a detent or tooth 8,

which. is adapted to engage with and play 'over the teeth 9,-said teeth being arranged in series concentrically about theaxis of 76 the spool. The arm of the pawl being of spring material releasably engages by its detenture the teeth 9, permitting the spool to be turned by the upper end or head 5, but

retarding the movement of thespool. The edge of the head is knurled at 10 to facilitate turning the spool by hand and the surface of sand head 15 marked with a suitable scale or dial 11 over which a pointer .12

mounted rigidly upon the shaft 2 indicates to position assumed by the spool when the 1 user is turned on its sup; shaft. in this manner the position assumed by the eccentric striker or lower end the radial the spool. can he predetermined by said scale so and pointer. The end of the supporting arm A opposite that on which the spool is l is formed with an opening l3,' which is adapted to fit over revoluble member such as the shaft 14: on a sound reproducing machine, said opening 13 being formed with'ilattened sides 15, which on gage corresponding flattened surfaces 11 the shaft 14-, so that the arm A is swung b'v the turning movement of the shaft 1%. loo

arm A may be provided with any suitable means for engagement with a movable part of any mechanism to which'my invention is applicable for use.

For the purpose of illustrating'the' man- 365 nor in which my invention can be used, I
