Patent number: 5451023Abstract: A retainer for holding a holstered handgun to a surface, such as a wall, under a shelf, or the like, the retainer comprising a bracket, formed having upper and lower legs, and being integrally bent at one end, so that the legs may extend generally parallel with respect to each other, for approximately equivalent lengths, and with the curvature of the bend being sufficient to provide adequate clearance within the bracket for retention of the strap of a holster therein. The legs of the bracket may be grooved, to provide inherent reinforcement and strength to it, during usage. The opposite or free ends of each leg are bent, to initially form shoulders against which the strap of the holster may encounter, so as to prevent its untimely release, while at the same time these bends contact each other, under a spring bias, to assure that the bracket remains closed, for retention of the holster thereto, when stowed.Type: GrantFiled: January 12, 1994Date of Patent: September 19, 1995Inventor: James R. Johnston

Patent number: 5287807Abstract: A personal check amount stamping device for printing the exact amount of a check to be written on the face of the check form, in at least three locations. This printing of the exact amount by the writer of the check insures that the bank will not mis-interpret the amount of the check, and also obviates the job of printing the check amount on the bottom of the check by the bank employees.Type: GrantFiled: September 17, 1992Date of Patent: February 22, 1994Inventor: James R. Johnston

Patent number: 4784416Abstract: The lock button on a door latch is slidable in a horizontal direction between a retracted unlocking position and an extended locking position wherein it blocks a latch hook release member from unlatching the latch, prevents inadvertent locking of the door and extends alongside a strike shoulder on the associated door jamb to provide a secondary latch.Type: GrantFiled: February 15, 1983Date of Patent: November 15, 1988Assignee: National Manufacturing Co.Inventors: Marlin D. Crown, James R. Johnston

Patent number: 4750237Abstract: A trolley assembly for a pocket door system comprises a central carrier having a plurality of rollers journaled for rotation thereon. A hanger member having a bolt portion which is threadedly received by the carrier includes a laterally extending pintle. The pintle is received within an aperture of a bracket member secured to an upper edge surface of a door. A locking member is insertable into the aperture after the pintle is received therein and includes an abutment portion selectively positionable in proximity to the hanger member. When inserted into the aperture, the locking member blocks relative movement between the bracket member and hanger member thereby preventing removal of the pintle from the bracket aperture. The door height is conveniently adjusted by removal of the locking member and dissociation of the bracket member from the pintle whereupon the hanger member can be selectively threaded inwardly or outwardly of the carrier.Type: GrantFiled: November 3, 1986Date of Patent: June 14, 1988Assignee: National Manufacturing Co.Inventor: James R. Johnston

Patent number: 4742645Abstract: A pocket-door assembly includes a pair of trolley assemblies fixed to an upper edge of a vertically disposed door. A header member is positioned generally horizontally over the door and comprises a central plate portion with a pair of integrally formed downwardly extending tracks for receiving rollers of the trolley assemblies. The header member is attachable to a standard dimension lumber member of the wood frame structure within which the pocket-door assembly is intended to be inserted, and is preferably a unitary extruded metal structure. A plurality of vertical stud members are fixed at their upper ends to the header member on opposite sides thereof defining a pocket within which the door is receivable. The stud members each comprise a metal channel member having a generally C-shaped cross section into which a standard dimension lumber piece is inserted.Type: GrantFiled: November 3, 1986Date of Patent: May 10, 1988Assignee: National Manufacturing Co.Inventor: James R. Johnston

Patent number: 4731902Abstract: A coil spring has elliptical openings in the end turns for non-rotatably receiving elliptically shaped studs which are press-fitted into the spring, the ends being respectively attached to a pair of mounting brackets.Type: GrantFiled: August 9, 1982Date of Patent: March 22, 1988Assignee: National Manufacturing Co.Inventor: James R. Johnston
-
Patent number: 4642844Abstract: A trolley assembly including a channel shaped body and a pair of frictionless bearing assemblies which include a split tubular spring liner constituting the outer race of the bearing and the wheel axle extends through the space between a plurality of roller bearings positioned between the axle and the outer race. End spacers are secured between the trolley wheels and the body for controlling the end play of the roller bearings and of the trolley wheels.Type: GrantFiled: February 22, 1985Date of Patent: February 17, 1987Assignee: National Manufacturing Co.Inventor: James R. Johnston

Patent number: 4643469Abstract: A latch for use with a gate includes a latch body having a planar mounting surface on a rearward side thereof with a pair of space apart flanges which receive a bolt in openings thereto. The bolt is positioned parallel to the surface of the gauge and is slidably and rotatably disposed within the flange openings. An enlargement on one side of the bolt will allow the bolt to pass through one of the flanges when in a predetermined angular position for removal. However an offturned end of the bolt extends rearwardly of the mounting surface, and the bolt enlargement is so oriented such that the bolt is not removable from the latch body when the body is normally attached to the gate.Type: GrantFiled: September 3, 1985Date of Patent: February 17, 1987Assignee: National Manufacturing Co.Inventors: James R. Johnston, Marlin D. Crown

Patent number: 4486917Abstract: A door closer includes a spring-loaded piston forming part of a conventional pneumatic dashpot, which retards the speed of a door during closing, and an elastomeric sleeve which is longitudinally compressed during opening of the door to retard the speed of the door during opening and to apply substantial resistance to further opening movement as the door approaches its fully open position. Closing speed of the door is also initially retarded by the compressed sleeve.Type: GrantFiled: February 12, 1982Date of Patent: December 11, 1984Assignee: National Manufacturing Co.Inventors: James R. Johnston, Cordell E. Meiste
-
Patent number: 4483044Abstract: Door speed is controlled by a pneumatic dashpot including a spring-loaded piston having a piston rod which extends through an elastomeric silicone rubber braking sleeve which is longitudinally compressed as the door opens to increase the friction between the piston rod and the sleeve. One or more enlargements on the piston rod provide increased friction as the rod moves through the braking sleeve to control closing speed and to provide greater wind resistance.Type: GrantFiled: August 8, 1983Date of Patent: November 20, 1984Assignee: National Manufacturing Co.Inventors: James R. Johnston, Cordell E. Meiste
