    Abstract: An improved movable-contact-stem operator is provided for a vacuum-type circuit-interrupter comprising a loosely fitting clamp-type contact-stem operator, which is retained in place by a suitable means, such as by a shoulder-bolt, for example. The movable-contact-stem operator has at least one pivot-aperture provided therethrough, which accommodates the contact-operator pivot pin, and upon suitable alignment with a pivotally mounted contact-operating lever, may, as a subsequent procedural operation, have the clamping bolt tightened upon the contact-stem operator, so that thereafter the operating motion is transmitted directly between the contact-operator and the movable contact stem without any torque, or rotational motion being transmitted to the usuallyprovided metallic sylphon bellows which maintains the evacuated condition within the vacuum circuit-interrupter envelope.

    Abstract: The invention relates to a power fuse assembly including a power fuse device having end ferrules and stab-type electrical contacts extending rearwardly from the end surfaces of the ferrules for electrically engaging stab-jaw connectors without protruding laterally beyond the lateral dimension of the power fuse device. This electrical interconnect design permits compact lateral packaging of a plurality of power fuse assemblies in multiphase electrical systems.

    Abstract: A switch contact structure including a pair of pivotally mounted, horizontally disposed contact fingers slidably positioned to laterally engage a blade or stab-type electrical contact therebetween, and a pair of vertically disposed flexible, resilient U-shaped shunts each having an upper arm and a lower arm; the lower arm being rigidly secured. The upper arms of the U-shaped shunts are fixed to electrically conductive lever arms protruding outwardly and laterally from the respective contact fingers. A magnetic field developed by a reverse current flow pattern through the arms of the U-shaped shunts causes a vertical displacement of the upper arm of the U-shaped shunts which imparts a rocking motion to the contact fingers which increases the contact pressure between the contact fingers and the stabtype electrical contact. The magnitude of the contact pressure is controlled by adjusting the active length of the lever arms by varying the lateral distance between the U-shaped shunts and the contact fingers.

    Abstract: An improved circuit-interrupter is provided having an improved operating mechanism for operating the separable contacts of the circuit-interrupter unit including a novel reverse-current loop structure enabling the separable contacts to be magnetically closed under higher contact pressure during the existance of high-fault conditions, and, on the other hand, when it is desired to open the separable contacts of the improved circuitinterrupter under heavy-fault conditions with the contacts welded closed, the improved operating mechanism, including the reversecurrent loop structure, operates in the opposite manner to assist the operating mechanism to open and to separate the separable contacts of the circuit-interrupter. The improved invention additionally contemplates an improved magnetic means associated with the operating mechanism for applying additional contact closing force to hold the contacts closed under additional increased force created magnetically and instantageously at the most appropriate time with the application of the high-fault conditions. Additionally, the same magnetic means is operable, taken in conjunction with the improved operating mechanism of the instant invention, to assist the opening of welded-closed contacts during the opening operation of the circuit-interrutper by a novel relocation of the fulcrum point, which is applicable and which functions in dependence upon either the energization or the non-energization of the operating magnet structure of the operating mechanism for the improved circuit-interrupter of this invention.
