Title: Automatic spring-powered battery charging device

Abstract: A battery charging mechanism which is driven by a coil spring. A gear train driven by the spring includes a wheel having peripheral teeth. A control lever is reciprocated pivotally by a small spring to engage the teeth of the wheel in a manner to control its rotation. The wheel in turn applies impulses which help to keep the lever in motion. Links connected with the lever turn gears which drive alternators in order to deliver charging current to the battery. An electric motor acts to automatically wind up the drive spring when it has uncoiled below a preselected tension level.
