Abstract: A clinchnail having an elongated shank with a head at one end and a tip portion at the other end thereof, wherein the shank is of essentially constant cross-sectional configuration throughout its length and the tip portion has a cross-sectional configuration differing from that of the shank, said tip portion being laterally offset from said shank with respect to the longitudinal axis of the shank.
Abstract: An expanding wire nail for fastening baseboards and the like to concrete walls has two aligned shank segments integrally joined by a ligament of cruciform cross-section forming a weakened zone between oblique wedge faces on the adjacent ends of the shank segments. The ligament and the wedge faces are formed by plastic deformation of the shank from opposite sides in a forming die assembly. The forming die assembly has opposed forming punches driven in phase opposition, each forming punch being driven in unison with one of two aligned tip cutting punches.
Abstract: A fastener package, for use in a fastener applicator apparatus and comprising a disc shaped carrier and a plurality of fasteners, each having an elongated shank and a head. The shanks of the fasteners pass through the carrier and the under surface of their heads rest on the carrier. The disc shaped carrier is circular and carries the fasteners evenly spaced on a circular line along the peripheral portion of the circular carrier. Also disclosed is an inherently stiff support and guide body which is useful as a magazine in the fastener applicator apparatus and which has teeth or grooves for a step-wise turning thereof in order to advance the fasteners, one at a time, to an application position in the fastener applicator apparatus.
Abstract: A nail has a series of embossments formed as wedge-like ramps arranged in a helical path between the head and tip of the nail, each embossment having a smaller end directed toward the nail tip, the cross-section of the shank being substantially constant.
Abstract: A machine for cutting material, such as wood comprising knives angularly adjustable around an axis and adapted to cut the wooden material angularly in cooperation with suitable anvils, each knife being journalled on a journal column which is angularly adjustable around said axis jointly with the respective anvil.
