Abstract
109,324. Steel Nut & J. Hampton, and Hampton, T. March 24, 1917. Cranks, variable-throw.-In a variable-throw crank for bicycles &c., the outer portion d<1> of a crank slides between grooved rollers o on the inner portion d and is connected by a rod g to an eccentric strap g<1> working in a fixed eccentric sheave h. In modifications, an eccentric or crank fixed on the pedal pin and connected by a rod to the inner part d of the crank, operates the sliding part d<1>.
