Jenkins' Upright Cushioned Helve-Hammer.—Fig. 1 shows a power-hammer made by Jenkins & Lingle, of Bellcfonte, Pa. The blow or stroke is cushioned by means of four rubber cushions, two of which are placed above and two below the fulcrum bearing the helve. This fulcrum is made in the form of a cross-head, to which the head is pivoted; the cross-head being free to move up and down as the strain comes on the helve. The makers claim that a cushion placed directly at the fulcrum is more effective than when placed at a distance from it, as every inch farther from the fulcrum requires proportionately more movement of the cushions to produce the same result on the ram. The end of the helve joining the ram is wood, and simply enters into an opening provided in the ram. |
