  • Patent number: 8366492
    Abstract: A terminal reversing block mounts to a standard electrical disconnect device such as a circuit breaker or a pullout switch. The disconnect device has a housing which defines a cavity that faces in one direction for receiving a cable. Front and rear contacts are in the housing, one of which extends into the cavity for engagement with a cable. A terminal reversing block has a housing with at least one pocket which faces in a direction other than the opposite of the direction in which the disconnect device's cavity faces. A terminal collar disposed in the terminal reversing block pocket is engageable with a cable inserted into the pocket. A terminal in the reversing block has a mating portion and a connecting portion. The connecting portion engages the terminal collar. The mating portion engages one of the front and rear contacts of the electrical disconnect device.

  • Patent number: 4103133
    Abstract: A dual switch actuator mechanism for coordinated actuation of two high-current switches, each of which includes a switch operator mechanism for opening and closing the switch in response to rotation of a switch operator shaft. The switches are mounted adjacent to each other with their switch operator shafts in aligned paraxial spaced relation. The dual switch actuator mechanism includes a rotatable main shaft positioned between and in aligned paraxial relation to the switch operator shafts. A Geneva drive plate having an arcuate bearing surface is affixed to the main shaft; two drive pins are mounted on the drive plate. Two modified Geneva follower plates are provided, each affixed to one of the switch operator shafts. Each follower plate has a drive slot for receiving one of the drive pins and an arcuate bearing surface which is complementary to the drive plate bearing surface.
