Abstract

173,595. Maycock, A. W. Oct. 1, 1920. Cranks, adjustablethrow. - In adjustable-throw cranks for power - hammers &c., the crank - pin d<2>, driving a rod e, is carried by an elbow extension d<1> of a round or rectangular block d, which is slidable in a radial slot c in a disc a keyed to a driving- shaft b. The block is spring - pressed towards the shaft, and can be moved outwards by a wedge g, feathered to the shaft b and secured to or integral with a collar h engaged by a forked lever i. The inclined face of the block b may be provided with an antifriction ball or roller k. In a modification, whereby the block is positively moved in either direction, the wedge g is replaced by an inclined tongue passing through an inclined slot in the block. The disc a may be solid, or may be constituted by a rim and spokes, one of which is enlarged for the slot c, a diametrically opposite spoke then carrying a. balance-weight. The disc may be encased in a housing j, which may serve as a bearing. Antifriction bearings may be interposed between the parts a, j. According to the Provisional Specification, the member a may be constituted by a series of discs.
