Abstract

341,036. Spring motors. REES, S., 105, Blackheath Road, and HUXFORD, G. E., 189, Greenwich Road, both in Greenwich, London. Oct. 3, 1929, No. 30067. [Class 10.] A spring motor for gramophones consists of a coil spring 3 connected to and surrounding a rack 14 which engages at one end a winding mechanism and at the other end the driven mechanism. The rack passes through slots in plates 4, 5 and carries an abutment 21 for the spring which also engages plate 4. Plate 4 carries a gear train 24, 27 engaging teeth 23 on the rack 14 and engaged by a worm 32 on a handle 30 normally pressed out by a spring 33. The rack is flattened at its other end and has on its face teeth 41 engaging a pinion 42 which drives the turntable 2 through a one-way ratchet 48 and gearing 51, 54, 58. The length of the handle 30 is so made that the handle hits the rack when the spring is fully compressed to prevent over-winding. The spring motor will play up to twelve records at one winding.
