Abstract: An adjustable roller assembly for sliding doors including a housing adapted to be snap-fit into a recess provided in the upper or lower surface of a door frame, the housing defining a cavity which is open at the lower end. A roller carrier is mounted in the housing cavity and is vertically adjustable with respect to the housing. The lower end of the roller carrier defines circular flanges in which is rotatably mounted a roller having an integral hub. A camming arrangement associated with the roller carrier is accessible for adjustment from the side of the door frame and is operable to adjust the vertical position of the roller carrier and roller to adjust the slack between the door and the track upon which the roller is adapted to ride.

Abstract: A square butt hollow door frame including upper and lower rail members, and a pair of stile members wherein the inner walls of the stile members are provided at each end with a recess defining inwardly laterally extending flanges adapted to be received in corresponding slots defined through each end of the upper and lower rail members, such that when the respective flanges are received in the respective slots, a locking mechanism is positioned, thereby securing the side members and rail members together to form a door frame.

Abstract: This invention relates to a rotary type latch for sliding screen doors wherein the rotary member is molded from a plastic material such as a polycarbonate and which is rotatable in either direction for universal application to either right hand or left hand door operations. The rotary latch engages a slot in a door pull molded from a similar plastic material and contacts the screen door frame through the slot to cam the door against a retaining channel mounted on a door frame. The rotary latch includes a plurality of flat cam faces affording multiple locking positions and which necessitate positive lock rotation to enable the latch to be disengaged. This latch mechanism is of particular usefulness for application to sliding patio screen doors where the screen door closes into a pocket within the side jamb of the patio door frame.

Abstract: This invention relates to an insulating device to be mounted at the inner side of an existing window and includes a plurality of spaced apart film curtains mounted on a roller at the top and having a rigid bar at the bottom adapted to run in channel shaped side tracks, with compressible sealing members in the track that are displaced by passage of the rigid bar and which then spring back to engage the marginal portions of the respective film curtains to press them against the side walls of the tracks to provide a sealed unit effectively sealing the side edges of the curtains against the circulation of air at these points.

Abstract: This invention relates to hurricane panel installations of the type designed to be installed to cover windows and doors against the effects of wind and atmospheric conditions which might otherwise have the effect of destroying the windows and doors and which includes a tamper proof security means of preserving the installation against unauthorized removal of the panel to gain entrance to the premises. This security means is installed at the outer side of the panel in engagement with a securing device to prevent withdrawal of the securing device and the security means is secured from the inner side of the panel where an intruder would not have access so that the panel could only be released from the inside by an occupant of the premises, after which it could be removed from the outside.

Abstract: A method of providing a member having a metal core with a nonferrous coating wherein the metal core affords strength and rigidity while the nonferrous outer coating, or cladding, provides a non-corrodible surface and wherein the cladding is of such uniform thickness that final forming of the member may be performed without penetrating or breaking the coating, or exposing the core. The cladding is applied by extruding the nonferrous material in a cross-axis die where it reaches a plastic state and passing the metal core through the plastic non-ferrous metal in the die with the high extrusion pressure creating heat to render the nonferrous metal in a plastic state and further extruding the nonferrous metal around the metal core as it exits from the die, whereby to obtain a wrought structure of the clad coating, without reducing the cross-sectional area of the core during the extrusion operations.
