  • Tapered threaded bolt with oval nut
    Patent number: 5304022
    Abstract: This invention relates to a bolt having a tapered tip comprising of corresponding opposite flat and partially threaded portions that engage an oval nut having elongated internal adjacent sides, the ends of which are void of threads to enable bolt/nut alignment when initially inserted and tightened. Additionally, the tapered threaded bolt has an arcuate shaped or rounded first and/or second thread for providing self-alignment and preventing gouging or digging of internal threads when being inserted or screwed into any conventional nut or oval shaped nut. Moreover, inadvertent contact between the bolt and nut while in the process of initial insertion will not preclude uninhibited correct bolt insertion into the nut.

  • Clamping screw device
    Patent number: 5030139
    Abstract: Improved pilot devices having inserts comprising a spring-loaded stirrup for clamping electrical conductors, together with a screw for adjusting the clamping action of the stirrup and for releasably locking the stirrup in a fully open position to permit insertion of an electrical conductor, a mechanism for quickly and easily releasing the stirrup when the conductor is in a desired position, and an attachment member for releasably securing the block to a mounting rail. Also, included are independent bus bars which can be selectively operated to create an open or closed circuit condition between two different spring-loaded stirrups in the pilot device.
