Abstract

316,026. Johnson, N. G., and Auto Electric Devices. Ltd. Aug. 11, 1928. Shring power-storing mechanism.-Means are provided whereby a spring motor, particularly for talking machines, which is intended to be wound up by an electric motor as described in Specification 299,645, may be wound up bv a hand lever. The insertion of the handle into the machine displaces a gear in the drive between the electric motor and the spring motor. In Fig. 1 the gear B is driven by the electric. motor and normally winds up the spring motor through a gear A, a long pinion a, and a pinion i. For winding up by hand, the screwed end e of the handle f is screwed into a socket d in the enlarged end b<1> of the shaft b. A sleeve h is connected to the end b<1> bv a pin and slot b<2>, h<1>, so that they rotate together. When the handle is screwed in, a flange g bears on the sleeve h and moves the gear A out of mesh with the gear B. The pinion a moves against a spring c, but remains in gear with the pinion i. Two modifications are described.
