Abstract

161,046. Clark, W., and Clark's Neo- Electric Devices, Ltd. Feb. 20, 1920. Hand driving-mechanism.-Relates to cranked handles for imparting rotation to mechanism of various kinds and of the type which are hinged so that they can be folded flat against the cover, base, or other part of the mechanism, and comprises a handle capable of turning about the axis of the crank between an operative and an inoperative position in either of which it may be secured by yieldable means, the arrangement being such that the force required to drive the mechanism is applied in the same direction as the force required to maintain the handle in operative position on the arm. In the form shown, the crank b of a shaft a passes through an aperture in the end of the arm d carrying the handle f. The arm d is formed on its lower face surrounding the crank b with two ratchet teeth g, Fig. 2, adapted to engage a pair of similar teeth on a collar h fixed to the crank b, the teeth being so disposed that the driving-force on the handle acts to maintain it in operative position. A spring i secured by a screw j holds the members d and h in resilient engagement. Notches m, Fig. 4, are provided on the collar h in a position at right-angles to the ratchet teeth q so as to engage the teeth on the handle arm d when the handle is folded flat against the cover.
