  • Patent number: 5654595
    Abstract: A device for regulating the flow of electrical current to a power tool includes a switch and handle combination coupled to a wiring component which serves to bypass an electrical circuit of a power tool. In a first embodiment, the wiring component can be "hard wired" into the electrical circuit of a power tool in a permanent arrangement. In a second embodiment, the wiring component is self-contained, and includes a power cord bisected by a junction box, the junction box for accepting the plug adaptor of a power tool. An anchoring device serves to anchor the switch and handle to an accessible location upon the power tool, so that the switch may be easily reached, should a user need to increase, decrease, reverse or stop the flow of electrical current to the power tool motor.

  • Patent number: 4175728
    Abstract: The present disclosure describes an improved clamp for use with belted cables in the assembly of electronic equipment. In performing its clamping function, the device is adapted to engage the chassis structure upon which the cables are to be routed and terminated. The clamp design is characterized by its effectiveness with a single flat cable or a bundle of such cables. An increase in the clamping pressure exerted upon the cables results in a proportional increase in the force with which the clamp engages the chassis. This assures that the clamp will remain firmly in place during the assembly operation. Moreover, during such operation, the clamp may be easily removed to permit the addition of another cable and then reapplied. Finally, when the wiring of the cable bundle has been completed, the clamp may optionally be removed for use at another location or permitted to remain permanently in place.
