Abstract
Abstract A nail holder having nail holding jaws mounted on levers pivoting at a position such that good leverage can be applied for gripping a nail, the undersides of the jaws providing a cavity receiving a ridge of corrugated roofing, the tool being formed in a manner for economical manufacture from materials sufficiently malleable as to withstand hammer blows, some of the levers being formed of steel bars twisted for ease of pivotal attachment.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
276 words
A nail holder having right and left elongated levers, means attaching said levers pivotally together at their forward end for rotation about an axis, said levers being disposed alongside each other and being spaced apart with respect to each other in directions transverse to the elongation of said levers, right and left nail-gripping jaws each mounted on a respective one of said right and left levers, said jaws having opposed nail-gripping surfaces adapted to grip a nail therebetween when said jaws are held in a gripping position, said jaw surfaces being disposed in positions between said axis and the opposite ends of said levers and being disposed much closer to said axis than to said other ends of said levers, said jaws each having a horizontal dimension as measured in a direction transverse to the length of said levers which dimension is more than the corresponding transverse dimension of the respective lever by a multiple of at least 2, said nail gripping surfaces forming a nail groove when said jaws are held in said gripping position, said nail groove being vertical and parallel to said axis, said levers extending at an acute angle upwardly with respect to said axis, said forward lever ends each being twisted 90° so that their forward ends are horizontal, said levers each having the same transverse cross-sectional shape substantially from their rearward ends forwardly to said jaws so as to be manufacturable from bar-stock, and the jaws protruding below said levers and defining a concave recess perpendicular to said nail groove and transversely extending with respect to said levers, said recess being for placement over the crest of corrugated sheet metal.
