Abstract: Wooden members are joined with sheet metal connector plates having integrally struck teeth projecting from one side. The wooden members are placed between first and second pressheads. A coiled composite of connector plate stock has first and second lengths of connector stock in juxtaposition and with intermeshing teeth. The first and second lengths of connector stock are unwound separately and oriented so that the teeth thereof point toward the wooden members to be joined. A cutting means associated with the pressheads cut connector plates from the stock and the plates are positioned on opposite sides of the wooden members and at the junctures to be joined. The pressheads press the plates into the wooden members. The connector stock is provided as a free coil and has the advantage that no spool, reel, or like supporting device is required. Further, the composite of connector stock has no teeth projecting from outer surfaces thereof.

Abstract: A clip for attaching together planar wooden or like members comprising a one-piece sheet metal element having a flat base adapted to be seated on one of the members and provided along one edge with an outwardly open socket-like formation above a surface of its base for abutting engagement with the other of the members, the base having a bent nail portion formed by material displaced out of said base to leave an opening in the base and comprising a shank portion extending at an acute angle from an edge of said opening away from the base surface and the opening and a tip portion extending from a transverse bend toward the base opening and being adapted to angularly penetrate the one member, the included angle between the shank and tip portions being an acute angle, and the tip portion being bifurcated with the free ends of the bifurcations having oppositely lateraly outwardly inclined edges.

Abstract: A clip for securing planar members, such as tongue and groove pine boards, panel boards and flooring, to wooden supports, such as furring strips. The clip is formed from a metal plate and has first and second portions struck out from the plate. The first and second portions both extend outwardly from the plate in the same direction. The first portion is angularly bent so as to form an L-shaped finger member capable of engaging a peripheral edge of the planar member to be secured to the furring strip. The second portion has a free pointed end and is angularly bent so that it can be driven back across the plane in which the plate lies and then driven into the wooden support member to which the planar member is to be secured.

Abstract: An assembly machine for embedding connector plates in wooden structural members includes a plurality of work stations which can be adjustably positioned along a support frame. Each work station includes a table having a work support surface and an upright C-shaped frame member balanced on a pneumatically operated cylinder and movable upward relative to the table. The frame member supports a lower platen at a rest position slightly below the work support surface and an upper platen movable downward toward the lower platen by a hydraulic power cylinder. Upon actuation of the hydraulic power cylinder, the upper platen is pressed downward into engagement with an upper connector plate on top of the wooden structural members and the lower platen is raised relative to the work table to press a lower connector plate upward against the wooden members. The upper and lower platens apply uniformly distributed forces to the connector plates which are firmly embedded in opposite sides of the wooden members.

A coiled composite of connector plate stock has first and second lengths of connector stock in juxtaposition and with intermeshing teeth. The first and second lengths of connector stock are unwound separately and oriented so that the teeth thereof point toward the wooden members to be joined. A cutting means associated with the pressheads cut connector plates from the stock and the plates are positioned on opposite sides of the wooden members and at the junctures to be joined. The pressheads press the plates into the wooden members. The connector stock is provided as a free coil and has the advantage that no spool, reel, or like supporting device is required. Further, the composite of connector stock has no teeth projecting from outer surfaces thereof.

Abstract: An assembly including a mechanism for retaining a rotatable member, such as a caster, mounted on an elongated member, on a support. The support, such as, for example, the bottom of a sofa, has a bore hole for receiving the elongated member. A planar metal plate having a central opening is secured to the support so that its opening is aligned with the bore hole. A plurality of teeth are struck from the metal plate so as to project outwardly from a side face of the plate. The struck teeth leave a plurality of corresponding slots in the plate. The plate is secured to the support bearing the bore hole. A resilient member having a central opening is positioned between the plate and the support so as to be in alignment with the opening in the plate and the bore hole. When attaching the elongated member, on which the roller is mounted, to the support, the elongated member will pass through the opening in the plate and the resilient member into the bore hole.

Abstract: The method includes the use of a conveyor table mounting press assemblies above and below the table respectively. Coils of connector plate stock having prepunched integrally extending teeth feed upper and lower press platens of the press assemblies, the platens being movable toward one another to substantially simultaneously cut the connector stock to predetermined lengths to form connector plates and embed the teeth of the connector plates on opposite sides of a joint formed by a pair of wooden frame members disposed in end-to-end butting relation on the conveyor between the press assemblies. To join a pair of wooden members end to end in butting relation, the members are displaced forwardly along the conveyor table with the trailing member offset laterally from the leading member until the offset member butts a stop which locates the butt joint in accurate registration between the press platens. Clamp cylinders displace both members against a fence to longitudinally align the members.

Abstract: The bed frame includes a pair of side rails, end rails and intermediate slats in coplanar relation. The slats and end rails are secured at opposite ends to the side rails by plates of the type having a plurality of teeth struck to project to one side thereof. Particularly, the plates are embedded on opposite sides of the joints formed between the ends of the slats and end rails on the one hand and the side rails on the other hand. A central support strip of sheet metal underlies the intermediate slats and its ends overlie the end rails. The central support is secured by plates of the foregoing type wherein the teeth pass through the strap and are embedded into the underlying wooden end rails. In one form hereof a corner plate is provided for joining the ends of the end rails to the ends of the side rails. The corner plate includes a sheet metal plate formed to provide channel shaped portions at opposite ends which extend at right angles to one another with inside and outside radii therebetween.
