14, carried by the motor-shaft The two disks embrace the clutch-drum 6 and each engages a washer 18, of any suitable frictional material, and presses said washer against the disk 11, thus yieldingly holdin the said disk relatively to the clutchdrum 6, and causing the latter, through its balls 9, to drive said disk and the motorshaft on which the'disk is mounted. A ten sion-spring 19 looselyy irclesthe collar 15, and one end 20 of said spring is fixed to the bracket or arm 13, 'while the other end 21 is fixed to the clutclrdrum (s; and the spring so wound as to yieldingly oppose the clutch action of the drum 6 and disk 11, and to separate the drum and disk after the motor-shaft has been wound. The winged nut 16 will be set so as to create suflicient friction upon the disk 11, through the medium of the washers and disks 14 and 17; but will not be set so tightly as to bind the disk and shaft rigidly together, the object of this construction being to permit, under excessive stress of the cable, the clutch and disk to rotate iis a unit on the shaft in oppositionto the winding action, thus avoidint, accident or too much winding drive upon the motonshaft.

The operation of this form of my invention will be readily understood upon reference to Figs. 1, 2 and 3, where n it will be seen that, with the outer end of the cable fixed to the device 4 and its inner end wound about the clutch-drum and properly secured thereto, an outward pull upon the drawer 12, to open the same, will result in stress upon the cable 5, which will cause the drum 6 to rotate in the direction of the arrow at, Fig. 2, with an initial tendency to loosely run upon the disk 11. The form of the cam-recesses 8, however, is such as to almost immediately drive the balls 9 into the small end of the recesses. thus making a fast connection between the cluteh-drum 6 and disk 11, which will become effective through the disks 14 and 17. and their washers, to wind the mo tor-shaft 10. the same action winding up the spring 19 and storing power therein for the purpose of enabling it to perform its function when the winding action is complete. With the drawer open, as shown in Fig. 1, the motor will be stored with power, a disk may be extracted from the drawer, applied to the machine and the latter set in operation, the drawer thereafter being closed, thus releasing the clutch-drum and disk, which will be returned to normal position to wind up the slack of the cable 5, upon the drum 6, through the medium of the spring: 19.

In the form of my invention shown in Figs. 4: and 5, the clutch-drum 22 is provided with gear-teeth 23, which mesh with the segmental rack 24, connected in any suitable manner, at its outer end, to the lid 25, 6

of the cabinet 1. The motor-shaft, disk, balls and recesses are all indicated by the same reference characters in this form of my invention as in the form shown in Figs. 1, 2 and 3. In fact, the only manner in which the form of my invention shown in Figs. 4 and 5 differs from the other form is in the rack and pinion for driving the mo tor-shaft 10.

Other forms of my invention could be herein shown; but, further illustration of the broad idea of means is deemed to be unnecessary. since it will be readily understood that, inasmuch as I believe myself to be the first to provide a so-ca1led self-winding motor for talking machines, all forms which are mechanical and functional equivalents will be comprehended by the broad claims appended to this description.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. In combination, a cabinet for a talking machine, said cabinet having a movable part confined to right line reciproc'ations, a motor mounted in said cabinet, a windingmechanism for said motor carried entirely by the shaft thereof, and a connection between the movable part of the cabinet and the Winding mechanism whereby, upon actuation of the movable part the motor will be wound by the action of the winding mech-' anism.

2. In combination, a cabinet for a talking machine having a movable part; a motor mounted in said cabinet having its drivingshaft extended at one side; a winding-mechanism for said motor mounted entirely on its shaft-extension within the cabinet; and a flexible connection between the movable part of the cabinet and said winding mechanism, whereby the motor may be wound upon operation of said movable part.

3. In combination, a support for a talking-machine having a movable part; a motor on said support, a winding mechanism for the motor carried entirely by the driving-shaft of the latter, said winding-mechanism comprising a clutch-member fixed to said shaft and a complemental member running loosely upon said fixed'member; means connecting the Winding mechanism with said -movable part, whereby when the latter is actuated the motor will be wound; and means for restoring the winding mechanism to normal condition after the motor is wound.

4. In combination, a support for a talking machine having a movable part; a motor on said support; a winding mechanism for the motor carried entirely by the drivingshaft of the latter, said winding mechanism including a clutch-member; a flexible connectinn between said movable-part and said 0imen-mechanism; and means for winding the, flexible connection upon the clutch-meek anism, whereby when the movable part is actuated the motor may he wound and thereafter the connection.wound upon the clutch mechanism.

In testimony whereof I have hereunto signed my name in the, presence of two subscribing witnesses.

GEORGE E. MOLYNEUX.
