ABSTRACT:
A battery charging device which is driven by a torsional spring. A gear train driven by the spring is coupled with 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. The gear train is also coupled with an alternator such that the intermittent movement of the gear train is used to drive the alternator. The electrical current produced by the alternator is used to recharge a battery. An electric motor operates in combination with the switch mechanism to automatically wind up the torsional spring when it has been unwound below a preselected tension level.
