11,092. Smart, G.E. Sept. 18. Shears. -- The inventions consists in devices for increasing the leverage and improving the grip. To accomplish the former object, the legs are made extensible either by tubes telescoping over them or by bars jointed to them. Either the legs are serrated and the telescoping-tubes locked wherever desired by pawls, or the tubes screw over the legs, or they slide over and are slotted so as to be fastened anywhere by using nuts on screwed pins projecting through the slot. In an application of the second method, the lower leg is bent away at right-angles close to the pivot pin, so as to be some distance from the upper, and it rests on swivelling feet. A serrated bar pivoted to it passes through a slot in the upper leg, and is engaged by a tooth at the end of a hand-lever pivoted to the upper leg. The improved grip is obtained as shown by having at the end of the proper jaws A hinged face jaws B, adjusted by milled-head screws C or nuts travelling along the proper jaws. The face jaws are broadened and channelled to prevent lateral slipping of the object.Cataloged By
