Abstract

4300. Harris, J. Feb. 22. Driving. - The winding of the spring motor of a gramophone is effected by moving a rocking frame carrying the record turntable, the sound - box and trumpet being fixed. A rocking frame 1, pivoted at 4 and carrying the turntable spindle 2, is connected by a chain 7 with the spring 5, to which a certain fixed amount of tension has already been imparted through its arbor 9 and by the aid of the ratchets 10 and pawls 11. Moving the frame 1 by a handle 6 away from the spring 5 gives extra tension to the spring 5, and when the handle is released the turntable is gradually returned to its initial position and is simultaneously rotated through gearing 23, 22, 21, 20, and 15 from a fixed rack 13. A governor is mounted on the spindle 26, and is controlled by a brake lever 29 which is adjusted by a thumb-screw 31. The sound-box is connected with the trumpet by a universal joint on gimbals.
