141 Circuit breaker retractable handle mechanism US169 1993-01-04 US5319168A 1994-06-07 Gary J. Hutko; Brian C. Livingston; Yu W. Chou
A retractable handle mechanism for controlling the operating handle of a circuit breaker. The handle mechanism consists of a housing which may be mounted on an electrical enclosure in which the circuit breaker may be disposed. Pivotally attached to the housing is a first lever which is movable between an on position and an off position. Retractably attached to the first lever is a second lever which is movable between a first position substantially adjacent the first lever and a second position substantially extended away from the first lever. The retractable handle mechanism may also be equipped with a lever restraining mechanism which allows the second lever to be non-movably disposed in either its first position or its second position. The retractable handle mechanism may also be equipped with a lever off locking mechanism which prevents the first lever from being moved from the off position to the on position.
142 Operating mechanism for throwing toggle switches US612467 1990-11-14 US5111009A 1992-05-05 Anthony W. P. Chan; Richard M. Phillips
A mechanism is provided for throwing several toggle switches together, especially toggle contact breakers, which are enclosed in an explosion proof container. A link between the toggles distributes manual toggling force over all of them from a single manual throw switch. The single manual throw switch may be located outside the explosion proof container and be connected to the link to the toggles through a wall, e.g., a moveable wall such as a door. In one practical embodiment, the link is an elongate tie bar for the toggles, and the manual throw switch is connected to the spaced apart forks which are geared together.
143 Two component operating handle for a primary circuit breaker US103076 1987-09-30 US4804807A 1989-02-14 Todd K. Knapp; Ronny D. Jergenson
A two component operating handle for opening and closing an electrical switch by a hook stick, the handle including a rigid portion mounted on the operating shaft of the electrical switch and a flexible portion mounted on the outer end of the rigid portion. The flexible portion including a pair of extensions extending outwardly to form an enclosed hook stick opening with the ends of the extensions terminating at a slot at the outer end of the handle so that the hook stick will be released from the opening on bending of one or both of the extensions to open the slot when the rigid portion of the handle engages a fixed stop.
144 Lever operator switch actuator US189479 1980-09-22 US4291213A 1981-09-22 Richard A. Felland; James A. Miller
A lever operated switch actuator has a resilient lever secured at its lower end to a bracket and having a control knob at its upper end. The bracket is secured to a supporting surface. A pair of switches having plungers are secured to the bracket on opposite sides of the lever. A lever stop member is secured to the bracket and has stops positioned on opposite sides of the lever and immediately above the switch plungers. The stops of the lever stop member are adjustable with respect to the switch plungers. The lever can be manually grasped at the control knob and deflected forwardly or rearwardly to depress a plunger which activates a switch. A lever stop contacts the lever once a plunger is depressed.
145 Formed pivot for toggle lever and method of making US020823 1979-03-15 US4250369A 1981-02-10 Robert E. Larkin; Earl T. Piber
A formed pivot structure for a pivotally operable lever mounted in a bushing such as a toggle switch lever bushing. The pivot is provided by a suitable through-hole, opposite blind holes or circular groove in the enlarged portion of the lever into which thin portions of the bushing, either perforated or unperforated, are punched from opposite sides of the bushing. This provides a pair of aligned pivots affording free pivoting of the toggle lever in one plane while retaining it snugly from wobbling out of said plane. The pivot is formed by the method of forming opposite thin sections in the bushing, forming notches in the toggle lever such as the through-hole, opposite blind holes counter-sunk if desired, or circular beveled groove in the enlarged, partial-spherical portion of the toggle lever, inserting the toggle lever within the bushing and retaining it therein in position while two punches are actuated to form the thin sections of the bushing into the corresponding notches in the toggle lever for a close fit while allowing free pivoting of the toggle lever in one plane.
146 Force transfer means for operation of a circuit breaker including rollers on an auxiliary operator and the circuit breaker handle US27550772 1972-07-27 US3800114A 1974-03-26 STROBEL A
An auxiliary mechanism for operating a circuit breaker handle is provided with a lever carrying spaced straight rollers that engage a handle mounted straight roller positioned therebetween, with the axis of the handle roller being at right angles to the axes of the lever mounted rollers. The lever and handle pivot are in perpendicular planes, and the axis for the handle roller is at right angles to the plane of movement for the handle.
147 Toggle switch lever US3604286D 1969-11-03 US3604286A 1971-09-14 FOREMAN JOHN B
The toggle switch actuator has a handle having a spherical portion which seats on the seat inside the bushing to provide the pivot action for the handle. The plastic insert in the bushing has a slot in which the handle portion having the opposed flats is guided while handle rotation about its own axis is prevented. The spherical portion of the handle is captured between the seat and the insert. Ears on the insert project through slots in the bushing into slots in the mounting plate to prevent any relative rotation of the bushing, insert or plate. The end of the bushing is rolled over the plate to complete the assembly.
