Abstract: A snap ring removal/installation tool for removing crescent shaped split snap ring from a snap ring retaining groove in a shaft. The tool comprises a flat, rigid body having a head at one end with an aperture extending therethrough. The aperture is comprised of a front section and a rear section. The front section is defined by a pair of spaced apart side walls joined by a curved front wall. The rear section is defined by a pair a spaced apart side walls joined by a curved rear wall opposite the curved front wall. The side walls of the rear section are spaced apart a lesser distance than the side walls of the front section, thereby defining laterally extending shoulders or ledges between said side walls of the rear section and the side walls of the front section. These shoulders serve as abutment members which engage the prongs of the snap ring to force the snap ring out of its retaining groove.

The door latch also has a burglary deterrent feature comprising a dead bolt bar assembly which is in a retracted position when the door is closed and in an extended position when the door is open.

Abstract: A door latch having an adjustable backset position which allows it to be used in doors having either a 23/8" backset or a 23/4" backset. The latch includes a latch housing having a pair of aligned openings comprising two longitudinally spaced apart openings in communication with each other via a relatively narrow passageway. A cam is movable between the two openings through the passageway to adjust the backset. The cam cooperates with a retract slide which is engaged at its front end with the latch bolt to retract the latch bolt. The retract slide contains two sets of teeth at its back end, one set of teeth being engaged by the cam when it is in a first backset position and the second set of teeth being engaged by the cam when it is in a second backset position.

Abstract: The present invention discloses a junction box cover without any metallic parts. The junction box cover includes a one-piece, non-metallic face plate with a generally flat upper surface and at least one cutout adapted to reveal an electrical receptacle. A non-metallic receptacle cap is shaped to fill and cover the cutout with a pivot at one end thereof for mounting the cap flush with the upper surface of the face plate when in a closed position, and for exposing the receptacle when the cap is in a open position. A non-metallic retaining bar is utilized to secure the pivot of the cap to the face plate and to provide a retaining pressure for maintaining the cap in an open position.

Abstract: The present invention discloses a poke-through connector assembly which may be assembled in an aperture within a concrete floor from only one side thereof. The connector includes a molded basket of electrical and thermal insulating material having an upper surface joined to a lower surface by integral columns. A flange extending from the upper surface prevents the connector from passing through the floor aperture, while a spring clip attached to the lower surface of the basket prevents the withdrawal of the connector. An electrical conduit is attached to the lower surface of the basket by the spring clip. Intumescent material placed within the basket expands to fill the aperture within the floor when a fire on the lower surface of the floor heats the connector. The conduction of heat from the fire through the connection is reduced because the insulating basket provides no metal conductive path from the electrical conduit and the spring clip to the upper surface of the basket.

Abstract: A cable clamp for use in an electrical box or the like for locating, holding and grounding cables fed into the box and through the clamp. The cable clamp is mounted within the electrical box adjacent the knock-out openings using a single fastener to retain one or two sheathed cables. The cables are clamped between walls of the clamp which includes an end abutment wall having a pair of apertures through which the conductor wires are fed. The abutment wall positionally locates the sheath of the cable. The clamping walls are brought together to retain the cable as the single fastener is tightened. The clamping walls include inner ribs which receive maximum clamping force via a stiffener flange and a small bearing surface to securely engage and position the cable. The cable clamp is integrally formed from a single piece of material, preferably steel.

Abstract: A concealed mounting assembly includes an outer post member and a decorative rose plate mounted on a concealed bracket which has a post section and mounting plate section. The post has an axially extending bore which receives the post section of the concealed bracket. A securement nut is placed within an axially extending recess in the post section. The post section also has an elongated aperture extending from the recess. The post and securement nut have alignable apertures therethrough a allow a threaded fastener to extend through the lateral aperture, elongated slot in the post section and the threaded aperture in the securement nut. The fastener, when tightened, secures the post and rose plate onto the concealed bracket and allows axial adjustment for manufacturing tolerances and secures the mountable post against torque forces.

Abstract: A selectively self-locking deadbolt latch for incorporation into doors or the like. The latch can be preliminarily "armed" such that as the door closes the bolt will extend into the opening of the door strike. The latch mechanism includes a cam lever having a shoulder which loads against the bolt extension. A compression spring within the bolt urges the bolt towards the locked position once the cam lever is released from the bolt extension by closing the door. The temporary retraction of the bolt as it engages the door strike releases the bolt and cam lever. A beam spring acting on the cam lever urges the cam lever forward towards the locked position. The bolt is initially armed by turning the inner turn lever slightly or by depressing the end of the bolt which includes chamfered edges to allow the bolt to move past the door strike for release.

Abstract: A reprogrammable lock assembly of the wafer tumbler type which includes a plurality of wafer-type tumblers and cooperating followers mounted in a cylindrical plug and housing. The tumblers are movable radially in the plug to project beyond the plug into restricted pockets in the housing to maintain the lock in a locked position. A driver and adapter disposed in the opposite axial end of the housing from the key hole. The driver and adapter prevent rotation for unlocking unless a key having the proper length is inserted. In addition, the key must have the proper configuration to draw all of the tumblers within the confines of the plug in order to rotate the plug for reprogramming or unlocking of the door. The lock assembly is operated with a reprogramming key and a use key. A reprogramming key is used to rotate the plug to a resetting position which allows the tumblers to separate from the followers.

Abstract: A molded junction box is shown having four sidewalls, a closed bottom, an open top, and clip receiving columns on two opposing sidewalls. The clip receiving columns each have an aperture therein with four sidewalls and four sloping surfaces that join the four sidewalls to a clip receiving surface at the open top of the junction box. A U-shaped clip is received within the aperture whose sloping surfaces aid assembly and provide a guide for the fastener insertion.

Abstract: A door latch having an adjustable backset position which allows it to be used in doors having either a 23/8" backset or a 23/4" backset. The latch includes a cam which extends and retracts the latch bolt and has a rotational axis which is movable between the backset positions. The cam lever cooperates with a bolt extension which adjustably engages the bolt such that upon transposition of the cam lever, the bolt extension is adjusted relative to the bolt accordingly. A cam stabilizer plate prevents adjustment of the backset once the latch is installed.

Abstract: A self-adjusting door strike for a bolt assembly which adjusts to existing door conditions by deflecting a resilient member against the bolt of the door thereby eliminating rattle. The strike includes a conventional strike plate having a compensating member spanning the strike opening. The resilient compensating member can be in the form of a resilient plastic member or rollers axially mounted to a spring-wire. This compensating member engages the bolt to prevent the door and bolt mechanism from rattling within the strike while also compensating for shrinkage or warping of the door.
