Abstract: A door assembly with an automatic misalignment accommodating finger guard comprising a door panel assembly having a panel member having an edge space and a door edge defining member including an inner portion configured to be positioned in an operative relation within the space by a relative longitudinal movement with respect to the panel member. A longitudinal position determining member is detachably fixed to the door edge defining member in a position to extend within a longitudinal position determining opening in the elongated panel member. A spring system is provided which acts between the door edge defining member and the panel member to resiliently bias the door edge defining member into a longitudinally determined limiting position.

Abstract: A cylindrical lockset (20) includes an inside subassembly (22) and an outside subassembly (24) which are assembled with a door (208). Each subassembly (22, 24) includes a liner (26, 36), a rose (28, 38) and a lever (30, 40). A chassis assembly (58) includes a pair of sleeves (66, 68), a pair of spring plates (146, 192), a pair of torsion springs (166, 194), a cap (172), a case (182) and a retractor (70) which is coupled to the latchbolt (46). Upon operation of either of the levers (30, 40) from a non-operated or home position, the latchbolt (46) is retracted and the associated one of the springs (166, 194) is tensioned so that, upon release of the levers, the springs return the levers to the home position.

Abstract: A cylinder lockset (30) includes a chassis assembly (72) with sleeves (80) and (81). A pair of liners (36) and (48) are mounted on sleeves (80) and (81), respectively, and facilitate attachment of chassis assembly (72) with a door (260). A pair of spring cassettes (38) are mounted on sleeves (80) and (82). A pair of levers (42) and (54) are mounted on the sleeves (80) and (82), respectively, and operate cassettes (38) directly for spring return of the levers upon release thereof. A pair of posts (388) and (390) are mounted on liner 48 and are formed with score locator lines (412), (414) and (416) to locate the liner relative to a housing (74) of assembly (72). Liner (36) is formed with four mounting holes (356), (358), (360) and (362) which facilitate use of the liner with either a lefthand or right-hand door mode.

Abstract: The invention contemplates an improved set-screw shaft mounting for a machine element such as the inner race ring of an antifriction bearing. Tolerances are closely controlled for both the set-screw threads and the tapped-hole threads, for the case of set-screw threads which are yieldable in the context of an interference (i.e., friction-fit) to the tapped hole, the interference being such as to occasion a friction torque which is but a small fraction of the conventional maximum comfortable torque of wrench application by a machinist, using a conventional wrench, such as an Allen wrench. The low friction torque enables the machinist to know precisely when the set screw intercepts the shaft into which it is driven, and he can then know that his manually applied maximum torque will be serving essentially only the intended purpose of clamping to the shaft. Extended running life is realized for bearings thus mounted, as compared to conventional set-screw clamping.
