Abstract: The fastener comprises a sheet metal plate bent to provide two or more angularly related planar plate portions. One of the plate portions has a plurality of elongated nail-like teeth struck therefrom for embedment into one of the joint members. The other plate portion or portions have a plurality of elongated teeth each comprised of angularly related shank and tip portions. The shank portions extend from and form an included angle with such other plate portion. The tip portions extend from the shank portions in a direction toward the plate portion from which the tooth is struck and are poised for insertion through the respective slots for embedment into another of the joint members. Inside and outside connectors are formed depending upon the orientation of the teeth in the plate portions.

Abstract: This invention relates to a connector plate for joining wooden members comprising a planar metal plate having at least one pair of teeth formed by being struck from the plate so as to form a single opening therebetween with the teeth extending in a direction that is approximately perpendicularly and with the width of one of the teeth at its root being greater than the width of the other tooth at its root, and the length of such one tooth being greater than the length of the other tooth.

Abstract: There is provided a fastener for forming lap-type joints wherein a sheet metal plate has a plurality of teeth projecting in a substantially perpendicular direction from both sides of the plate. On one side of the plate the teeth are in rows of single teeth and on the opposite side of the plate the teeth are in rows of pairs of teeth. The ends of the single teeth are such that upon movement into a nailable member the teeth remain substantially perpendicular to the plate, while the ends of the paired teeth upon movement into a nailable surface are displaceable from the perpendicular direction and accomplishing a clenching between adjacent paired teeth. The paired teeth are of smaller cross-sectional area than the single teeth and may be placed into relatively fragile or thin material to provide secure fastening thereof to a more substantial material, e.g. wooden studs and the like.

Abstract: The joint includes a pair of connector plates each having a plurality of teeth struck therefrom for embedment into the ends of wooden members forming a part of a truss or frame. The teeth are distributed over the major portion of the plates inset from end portions thereof. Openings are provided in the plate end portions. In one form hereof, the metal about the opening in one plate end is extruded through the opening in the end of the other plate whereby the extruded metal forms a bearing surface for pivoting the plates relative to one another. In another form, teeth are struck from marginal portions about the opening of one plate and received through the end opening in the other plate. These teeth are formed over to effect a bearing surface. Bolts or rivets may also be used to pivotally connect the plates one to the other.
