Abstract: An improved astragal and flush bolt assembly to be secured to a relatively stationary member such as a door jamb or to the edge of an inactive door of a pair of double doors or the like. The astragal assembly includes a flat metal body mounted on the edge of the stationary member and a metal stop member secured to the body along one edge thereof. The flat body includes first and second spaced apart legs extending outwardly from the stationary member with the flat body and legs defining a channel to receive and retain a door latch bolt from the active door. The stop member prevents movement of the door in a first direction and when the latch bolt is engaged in the channel, the channel and latch bolt prevent the door from moving in the opposite direction.

Abstract: The apparatus includes a conveyor table having pairs of press heads mounted on its opposite sides. Strips of sheet metal stock from coils are fed through respective die sets for punching integrally extending teeth in the metal strips and the connector plate stock thus formed is fed into the respective paths of movement of upper and lower press platens. The platens are 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 joints formed by wooden frame members disposed on the conveyor between the press heads. Simultaneously with the pressing operation, the die set punches additional teeth into the strip. Upon completion of the pressing operation, a feed mechanism locates predetermined lengths of connector stock with struck teeth between the press platens for the next cut and embedment operation.

Abstract: The connector plate has a plurality of slender nail-like teeth struck to project at right angles to the plate for embedment into adjoining wooden members. The teeth are struck in longitudinal rows with the teeth in each row being staggered longitudinally relative to the teeth of next adjacent rows. The teeth in every second alternate row are struck such that the slots left thereby in the plate extend from the teeth in like directions while the teeth in the next adjacent alternate row in are struck such that the slots left thereby in the plate extend an opposed longitudinal direction to the slots formed in adjacent alternate rows. The teeth in the rows between such alternate rows are formed in longitudinally spaced pairs with each pair of teeth struck to jointly define a slot in the plate, the teeth being located at opposite ends of the slot.

Abstract: The apparatus includes a pair of spaced conveyors for conveying upper and lower frame plates through a pair of nailing assemblies. Each nailing assembly includes a nailing gun pivotal between upper and lower positions whereby nails can be driven through the plate and into a stud disposed between the plates at positions spaced along the width of the plate. The conveyor includes a drive unit for advancing the plates through the nailing assemblies discrete distances of 1.5, 16 or 24 inches. One of the conveyors and nailing assemblies is movable laterally relative to the other conveyor and nailing assembly whereby adjustments in width of the frame undergoing fabrication is accomplished. In use, a stud is butted against retractable stops upstanding between the nailing assemblies. Upon command, clamps carried by the nailing assemblies clamp the stud and frame plates one to the other and the nailing gun automatically drives a nail through the plate into the stud.

Abstract: The apparatus includes slat and rail conveyors which pick up slats and rails from respective hoppers on the input side of the machine and convey the slats and rails into joint forming positions between vertically opposed pressheads mounted on opposite sides of the machine. Coils of connector plate stock, having prepunched integrally extending teeth, feed each of the upper and lower press platens and which platens are 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 into opposite sides of the joints formed by the rails and slats disposed between the pressheads.
