Abstract: A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied.

Abstract: A cold or hot-forging heading die used in metalworking to form a “head” on the end of a metal rod is configured to provide two heading cavities formed in opposite ends of the carbide insert. The heading die of the invention comprises a hardened steel ring with a cylindrical carbide insert having a through bore with a first cavity machined concentrically with the bore in one end of the carbide insert. The die is then inverted and a second cavity formed in the opposite end of the insert. The second cavity can be identical to the first cavity or provide the shape for an alternate head configuration.

Abstract: A clamping jaw for gripping wire stock used in nail production machines includes a quick change system that allows efficient replacement of a removable tool insert. The clamping jaw includes a main body that is partially split so as to define a gap between first and second opposing clamping fingers having a recess portion there between for receiving and retaining the insert. The main body includes a top surface, a bottom surface, a central bore that extends between the first and second surfaces, and a countersunk cavity formed in the bottom surface. A tapered projection formed from the first and second clamping fingers extends into the countersunk cavity. A clamping member, having a tapered recess for receiving the projection, is positioned in the countersunk cavity. A fastener is tightened to draw the clamping member onto the projection to close the clamping fingers in order to grip the insert.

Abstract: The present invention is for a method of fastening a tool holder. The tool (2) has a front side (6) shaped for use in cold forming of metal wire into nails, screws, etc. The tool holder (4) has a recess (8) shaped for receiving the tool (2). When the tool (2) is fastened in the tool holder (4), compressive stresses are initially present in the tool (2). The tool (2) is subjected to tensile stresses caused by the nail making process when in the tool holder (4). In order to reduce the resulting tensile stresses, the two opposite and wedge-shaped sides (10, 12) of the tool (2) are compressed against corresponding sides (14, 16) in the recess (8) by applying and maintaining pressure on the back side (18) of the tool with fastening means (20).

Abstract: A clamping jaw assembly and cutter assembly employed in machinery used to manufacture nails, screws, rivets, and similar objects starting with wire material. The invention includes a groove design having a smooth wave that reduces the wear rate of the groove improving the life expectancy of the hard material clamping jaw insert. A clamping jaw assembly and cutting assembly that are both easily accessible for permitting quick replacement and/or indexing of the carbide-clamping inserts.

Abstract: The present invention relates to a tool for the manufacture of an offset head nail, said nail comprising a shank and a head, said head being placed with its center being offset to the center of the shank, wherein said tool is one of a set of at least two tools acting mutually on a blank for a nail, said tool comprising a front side with a reception opening and a top side to be used when forming the head, said reception opening being shaped to form an impression in the blank and to fixate said blank during forming of a head on the blank. The invention further relates to a use of the aforementioned tool. Nails with offset heads are used in nail guns, where a strip of nails is used for shooting multiple times before reloading a new strip of nails.

Abstract: A blade punch for forming teeth in a connector plate, the blade punch comprising an elongated blade having a metal working tip at one end and a shank at the other end. The blade has an elongated cross-section defined by opposing parallel spaced planar side walls and opposing ends. Each end comprises a major end wall and a minor end wall which converge to end wall intersections, where the end wall intersections are eccentric to a plane parallel to and midway between said side walls. Each end wall intersects a side wall at an obtuse angle. The metal working tip has opposed air cut faces abutting one another along an air cut edge and opposed first and second forming faces, each of the forming faces abutting one of the air cut faces along an exterior edge. Each of the air cut faces is bordered by a portion of one of the minor end walls, a portion of one of the side walls, the air cut edge, and one of the exterior edges.
