Abstract
173,114. Frohn, J. Oct. 18, 1920. Toothed gearing.-Comprises means for yieldably mounting the transmission gearing of winding drums of the type having an internal driving- motor. The pinion d on the motor shaft drives the toothed ring i on the drum a through the medium of pinions e mounted loosely on arms f carried by a sleeve k. During normal working, the arms f are fixed against rotation by a lever g fixed to the sleeve k and having a slotted end engaging a blade spring h on the framing. In the event of the gearing experiencing heavy shocks, the spring yields to allow the arms f to rotate to a limited extent in either direction, and thus move the pinions e bodily with respect to the pinion d.
