Abstract

200,800. Luzy, A. July 13, 1922, [Convention date]. Dynamos, driving.-A portable electric lamp comprises a bulb 43, a dynamo 3, 4 for supplying it with current, and an axially expanding spring 38 for driving the dynamo. The spring is adapted to be wound up by a key 28, which turns a shaft 20, bevel pinions 30, 32, and a pinion 34; these pinions are mounted in a frame that travels upwards and compresses the spring as the pinion 34 runs on a fixed rack 35. The spring drives the dynamo through bevel-gearing 19, 17 connected to the shaft 20 by a free-wheel device. A detent 42 can be engaged with the rotary magnet 4 of the dynamo when the lamp is not in use.
