Abstract: A door frame assembly and method of mounting the same, which does not require the use of exterior fasteners to secure members of the door frame assembly to a support frame in a doorway of a building. A connecting member is securable to a support frame member. A doorjamb member is attachable to the connecting member. A trim member is attachable to the connecting member and the door jamb member. The connecting combinations between the connecting member, the door jamb member and the trim member are such that once the door frame assembly is fully assembled, the door jamb member and the trim member cannot be disconnected from the support frame member absent an intervening force.

Abstract: A frame for a window or door is formed of inner and outer frame sections that are connected together by a thermobreak strip. The outer frame section is formed of extruded aluminum strips. The inner frame section is formed of an exterior part made of extruded aluminum strips and an interior part which is formed of wood strips. The two parts are mechanically fastened together. The inner and outer frames are roughly of the same thickness so that the thermobreak is roughly centered within the frame wherein about three-quarters of the thickness of the frame members are formed of metal, with the thermobreak arranged therein and the interior, roughly one-quarter of the frame thickness, is formed of wood. Thus, the combined aluminum and wood frame, with the thermobreak provides a structurally stable and rigid frame with an attractive appearing wood interior.

Abstract: A metal building panel, such as a roof panel, has its longitudinal edges roll-formed to define integral male and female edge formations. Each edge formation includes an upstanding flange, a return flange angularly disposed with respect to the upstanding flange such that the distal portion of the return flange is spaced from the upstanding flange a distance greater than the distances other portions of the return flange are spaced from the upstanding flange. Each of the return flanges joins with a reentrant rib. The reentrant rib of the female edge formation joins with a return lip. Adjoining male and female edge formations of a pair of such panels may be readily inter-engaged to form a snap-lock connection. If desired, a further mechanically seamed lock may be obtained by the application of squeezing forces to the inter-engaged male and female edge formations of a pair of such panels.

Abstract: An improved cinch strap and backup plate, used to form an enlap joint between two overlapping roofing panels, is disclosed. The backup plate is provided with horizontally extending shoulders which protrude outwardly from each end of the plate. One shoulder provides support for the endlap joint during its assembly, while the other shoulder provides support for later installed endlap joints. The cinch strap is configured to conform to the contour of the roofing panels. The cinch strap is provided with spines which provide structural support, and drainage channels which help to clear moisture from the roof. The cinch strap is configured so as to engage other, aligned cinch straps in a head-to-tail arrangement. The improved cinch strap and backup plate provide a structurally stronger, weatherproof endlap joint.

Abstract: A hollow, thin wall, generally rectangular shaped corner connector key forms the frame corner and connects together the adjacent ends of tubular screen frame members. The legs of the L-shaped key form a hollow box-like corner portion, against which the frame ends are abutted. Integral leg extensions telescopically fit into and are frictionally locked against the interior wall surfaces of the frame members. The hollow, tubular cross-section shape of the key, whose box-like corner portion corresponds to the cross-sectional shape of the exterior of the frame members, and whose leg extensions correspond to the interior cross-section of the frame members, coupled with the frame member abutments and the frictional locking, substantially rigidifies the frame corner and resists out-of-plane twisting or bending of the frame.

Abstract: A plastic bracket assembly is provided for mounting a pedestrian crossing switch and sign on a pole. The assembly includes a plastic frame which circumscribes an open front of the assembly for receiving the sign, and a switch housing mounted on the frame adjacent to the sign. The bracket assembly is adaptable to fit a number of different sized poles merely by changing a top member which is removably mounted on the frame. The sign is formed of clear plastic, with indicia on its back visible through the plastic. The sign is held in place by the top member, and side tabs which are formed integral with the frame. Accordingly, no screws are required for mounting the sign. The bracket is mounted on the pole by two screws which extend through bushings formed in a strap which is integral with the frame, and which extends across the open front of the frame behind the sign.

Abstract: A horizontally adjustable door hinge, for hingedly connecting the vertical edge of a door to the adjacent vertical edge of the door frame, is secured upon an elongated metal strip which forms one of said edges. An enlarged opening cut in the strip loosely receives one leaf of the hinge. A plate overlaps the opening at the rear surface of the strip, and, the plate rear surface is overlapped by a back-up plate. The plate is rigidly fastened to the strip rear surface, and the back-up plate is secured to the plate by a mechanical fastening means that permits horizontal movement of the back-up plate relative to the fixed position plate. A number of sets of aligned screw receiving holes are formed in the leaf, plate and back-up plate. The holes in the plate are formed as horizontally elongated slots. At least some of the holes in the back-up plate are threaded, while others are of sufficient diameter to loosely pass a screw therethrough.

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: 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: 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: A press which is suitable for use in fabricating wooden trusses is disclosed, wherein the press includes a lower stationery press platen and an upper moveable press platen opposing the lower press platen. Bellcranks are mounted on the lower press platen supporting structure on opposite sides of the press. A transfer bar interconnects the upper ends of the bellcranks. A hydraulic cylinder connects the moveable, upper press platen and a bellcrank. Guide rods are provided to guide the moveable upper press platen during vertical movement above the lower press platen.The press exerts substantial pressures upon the trusses or the like being pressed between the platens, while maintaining the platens in a generally parallel relationship, in spite of uneven press loading.

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.
