Abstract: A door light assembly in which a door light and interior and exterior molding members are secured in a door by an improved security clip. The clip is formed from a single piece of spring steel sheet metal and is adapted to be attached to the exterior molding member by means of a screw. Portions of the clip engage the adjacent edges of the door light and the door to hold the door light in place in the door, while other portions of the clip provide an attachment for the interior molding member. The resulting construction provides greater security since the exterior molding member is locked positively in place by means of screws, while at the same time the construction is aesthetically pleasing in that the screw heads are concealed.

Abstract: A rigid building component such as a door, table top or the like, is formed of coarse wooden particles mixed with adhesive, and a solid wooden edge frame, positioned between a pair of damp, substantially parallel, cellulosic fiber webs. A heated press is employed to compact the combination, particularly between the edge frame and the cellulosic fiber webs where the coarse wooden particles are greatly compressed to provide a durable edge. Under the heat and pressure applied in the press the particles are consolidated into a solid structure, while the damp cellulosic fiber webs are converted to tough exterior skins bonded to the coarse wooden particles. The sides of the rigid building component are suitably deeply embossed to provide a decorative paneled appearance.

Abstract: A passive system for protecting a structure against high temperatures which consists of a thin protective foil of heat-resistant material such as stainless steel fastened to the face of the structure to be protected. When subjected to high heating rates, the local thermal expansion of the foil forms a blister bulging away from the structure to thereby create an air space which thermally insulates the structure.

Abstract: There is disclosed a door frame construction, preferably of metal, which comprises cross channel members assembled perpendicularly with a pair of parallel upright channel members to form a rectangular frame. The respective channel members are held in assembled squared relation by a novel type of joint construction, which joint includes a pair of elongate slots formed in ones of the channel members which slots cooperating receive first detent members formed on the other of the channel members. The first detent members prevent disassembly of the joined channel member in a generally lateral direction. In addition, said slot also cooperates with second detent members received therein, which preclude relative pivotal movement between the assembled channel members and thereby serve to maintain the channel members in squared relation.

Abstract: A support arrangement in a refrigerator having a hinged door to attach a hinge pin assembly to the cabinet outer case and to secure the outer case to a mullion. The outer case has a U-shaped portion, one leg of which has two spaced openings to receive fastener elements and the other leg has a slot located between the openings. The mullion has an edge abutting the edge of the outer U-shaped portion and also has an opening to receive a fastener element. A cross piece support member spans the abutment area and is inserted in the U-shaped portion. A first end of the cross piece support member has two openings to receive fastener elements and these openings are in alignment with the two spaced openings in the U-shaped portion. The first end also has a detent tang dimensioned and located to snap into the slot in the U-shaped portion to thereby retain the cross piece support member in its proper position relative to the fastener element openings.

Abstract: A door frame construction in which the jambs, threshold, lintel, and trim are of molded construction. The door frame may be molded in one piece and the jambs are provided with clips for attaching the jambs to studs framing the door opening. The clips are adjustably mounted on the jambs so that the door frame may be positioned properly despite misalignment of the studs to which the frame is attached. The jambs also carry clips for attaching the trim to the door frame, and these clips and the clips for mounting the frame on the studs may be formed integrally from a single strip of metal. The side and head trim are preferably formed separately and joined at the job site by means of a special corner construction which allows them to be joined without nails, screws or other external fasteners.

Abstract: A metal faced door for use as a replacement in existing door frame installations comprises a wooden frame providing a central cavity and pair of metal panels adhered on opposite faces of that frame with a synthetic resin foam core filling the cavity and bonded to both the wooden frame and the metal panels. The stiles of the wooden frame have longitudinally existing channels spaced from the side edges of the frame, and inturned lips on the side margins of the metal panels are fitted into these channels. The metal panels are dimensioned to terminate inwardly from the outer edges of the rails of the frame so that there is a peripheral margin of wood extending completely thereabout. In using this replacement door, it is mounted upon the existing hinges and any areas of interference are noted and trimmed. The location of the existing latch is also noted and the door is provided with the necessary apertures for the knob set and latch which are then mounted thereon.

Abstract: An entrance door with a plurality of extruded sections that are interconnected to form a rectangular frame, a glass panel mounted within the frame. The door is partially fabricated by punching openings at specified locations on the extruded sections. The openings are punched in a press that is provided with guideways and stops for positioning the extruded sections in alignment with a punching tool. The punched openings are configured to receive a lock mechanism and hinge hardware as well as tie rods that are used for interconnecting the sections.

Abstract: A fire resistant door, panel or building element is manufactured from unique compositions which are free of asbestos, thereby minimizing the health hazards associated with the manufacture of conventional asbestos-containing fireproof doors, panels or building elements. In essence, the compositions comprise calcium silicates, vermiculite, sisal fibers and fiberglass.

Abstract: This disclosure relates to a door which is resistant to hostile environments, such as corrosive chemicals, high humidity, etc., and includes a one-piece stile and rail fiberglass and resin reinforced collar, the collar being of an inwardly opening generally U-shaped configuration, the U-shaped collar being defined by a bight portion and opposite faces, and a fiberglass resin reinforced plate secured to the exterior of each of the faces.

Abstract: An integrally molded one-piece ornamental plastic shutter having marginal portions providing peripheral front surfaces and inner and outer top, bottom and side surfaces. A plurality of discrete slats extend between the inner side surfaces. The slats slope downwardly and are parallel to and spaced from one another. Their lower edge portions are extended rearwardly to simulate the appearance and the rigid feel of the slats of a conventional wooden shutter.

Abstract: A door light fastener for releasably mounting opposing sections of a door light frame in a door, wherein a plurality of pairs of opposed cylindrical bosses extend inwardly from each of the opposing door light sections, comprises a tubular spring clip that encircles and resiliently holds each pair of bosses together. Inclined barbs in the spring clips permit bosses to be inserted into the ends of the spring clips but inhibit removal of the bosses from the spring clips. A stop projection in each spring clip prevents the bosses from being inserted more than halfway through the spring clip.

Abstract: A jointing device for securing a horizontal frame member to a vertical frame member comprises a strip having its longitudinal ends extending beyond the vertical width of the horizontal frame member and including a central portion extending substantially over said vertical width. There are provided first holes formed through the central portion of the strip and second holes formed adjacent the longitudinal ends of the strip. The strip is first screwed to a longitudinal edge of the horizontal frame member through the first holes and then screwed to an inner wall of the vertical frame member through the second holes, thereby coupling the frame members together.

Abstract: An assembly for mounting a flat panel of glass or other material in an opening in a door frame. The assembly includes complementary molding sections, each of which has inwardly projecting studs which align with the studs on the opposite molding and are secured by tubular clips which slip over the studs. The clips also include outwardly projecting wings which engage the edges of the panel to support and position it in the door frame opening, and at least one of the wings is disposed at approximately 45.degree. with respect to a plane bisecting the clip. This construction allows the position of the panel to be adjusted by rotating the clips about their longitudinal axes.
