Latest Patents

Among his latest patents is a method and apparatus for making a self-thread creating fastener. This invention features a thread forming screw that has a helical thread and a tapered lead-in section with a polygonal cross section. The screw is formed from a conventional blank by rolling it between a pair of thread rolling dies. These dies create alternating convex lobes and concave relief areas in the frusto-conical surface of the blank. This design allows the screw to be formed with a polygonally shaped threading end without prior working of the blank's frusto-conical surface. The curved ramp surfaces smoothly interface the lobes and concavities, enabling the metal in a workpiece being threaded to roll into the concavities, thereby reducing the torque needed to form a thread in the workpiece.

Another notable patent is the tilting terminal clamp. This clamp includes a threaded shank extending from a head end, an integral annular plate retaining ring spaced below the head, and a plate featuring a frusto-conical annulus about the shank aperture. This design provides a concave surface that confronts the annular ring, with the annulus being sized and shaped to substantially receive the annular ring.
