Abstract: A levering and holding device is provided for positioning large circuit breakers in a switchgear compartment or cell. The levering and holding device comprises a box beam which can be secured to the cell walls and a rotatable threaded shaft which is connected to the beam. A threaded shaft has a nut threaded thereon and has one end fixed to the beam. The thread shaft may be rotated with a crank. The breaker is attached to the nut, and as the shaft is rotated, the nut is moved along the shaft and moves the breaker into position. Interlocks are provided to prevent the breaker from being levered into the cell when the beam is not engaged in the cell wall and to prevent the beam from being disengaged from the cell wall unless the breaker is in a fully disengaged position. Another interlock is provided so that when the breaker is closed and in the operating position the threaded shaft cannot be rotated to lever out the breaker.

Abstract: A circuit interrupter having relatively movable contacts, means for moving the contacts between open and closed positions which means include a support arm for the movable contact, a rotatable operating shaft, a drive structure between the shaft and the arm including a connecting link and a member extending substantially radially from the shaft and fixedly mounted thereon, the link and the member being pivotally connected, adjustable means for pivotally mounting the link on the member and comprising an elongated slot in the member and an aperature in the link which is aligned with the slot, a nut and bolt assembly extending through the slot and aperture and a bushing mounted on the bolt and within the aperture, the bushing having a cylindrical surface and having tapered annular ridges at each end thereof, whereby upon tightening of the nut and bolt assembly the ridges bite into the bifurcated portion of the member and thereby prevent movement of the nut and bolt assembly with respect to its desired location in the slot.
