Abstract: A face plate is disclosed for concealing the exposed edge of a lock mechanism when installed within the lock stile of a door. To accommodate the plunger and deadbolt of the lock mechanism, the face plate comprises a plurality of separation lines defining removable portions or "knockouts" corresponding to various lock configurations. Depending upon the configuration of the lock mechanism being used, a corresponding one or combination of the removable portions can be removed to accommodate the particular lock mechanism. In addition, the face plate comprises tabs at the upper and lower edges which hook beneath the vertical edge wall of the door stile adjacent the upper and lower ends of the opening within which the lock mechanism is installed. The tabs hold the upper and lower edges of the lock plate with the opening and can either reduce the number of screws required to secure the face plate to the door or can eliminate the need for screws altogether.

Abstract: A self-sealing framing system is disclosed for curtainwalls, storefronts, and other framing systems for buildings in which frame members are erected in a grid and infill panels set within the openings of the grid. An elastomeric weathering gasket is mounted to a first frame member such that a portion of the weathering gasket overlies a recess formed in a side wall of the frame member. In an undeformed condition the elastomeric weathering gasket normally extends through a plane defined by the side wall of the first frame member. A second frame member oriented substantially perpendicular to the first frame member has an end abutting the side wall of the first frame member. The end of the second frame member contacts the elastomeric weathering gasket and displaces it onto one side of the plane by the contact with the end of the second frame member. A portion of the weathering gasket is displaced into the recess in the side wall of the first frame member.

Abstract: An improved butt hinge is disclosed in which each hinge half comprises a leaf portion formed integrally with a butt strap. A second leaf portion mounts to each butt strap after the butt straps are mounted to a door and door frame. A hinge pin passes through each of the four leaf portions to hingedly mount the door to the door frame. The hinge pin cannot be removed without removing at least one of the second leaf portions, and since the second leaf portions cannot be removed while the door is closed, the hinge pin cannot be removed while the door is closed.
