Abstract

18,254. Williams, H. Aug. 7. Cramps.-Relates to cramps for frames, sashes, &c., of the kind in which adjustable corner clamps. or jaws are carried by arms pivoted in pairs to blocks adapted to be drawn up together by screwthreaded bolts rotated by bevel-gearing. The pivoted arms f are of T-shape in cross-section, and the undersides of their horizontal members are formed with teeth f<1>, adapted to be engaged by the teeth g<1> carried by the plates g. These carry the jaw-plates h provided with angled jaws i of varying depths and secured by projections h<1> embracing the plates g, whereby the jaws are readily adjustable for the size and depth of the frame to be operated upon. In the case of rectangular frames, the arms f may be pivoted to extension pieces pinned to the screw blocks e and passing through hearings j<1>. With square frames, one block c may be dispensed with, and one pair of arms pivoted to lugs on the central bearing b<1>.
