  • Straight edge guide
    Patent number: 4463644
    Abstract: Two rails, each having a straight edge, two ends and a cross section defining a channel, are placed in an end-to-end butting relationship to form a continuous straight edge. A joiner plate has an arcuate cross section and has lateral margins for being received in the rail channels. The plate is placed in the rail channels and is fastened to the rails so as to deflect the plate downwardly and force the lateral margins of the plate tight against the rails to align the rails and hold the rails together.

  • Three piece knob assembly including a cap
    Patent number: 4413374
    Abstract: A two-piece knob assembly is provided for positively holding a fastener in a non-rotatable condition. The assembly includes a knob that has an aperture with varying diameters and configurations. A fastener is received in the aperture and is non-rotatably held therein due to the mating irregular configurations of the knob and the fastener.
