With a total of three patents to his name, Chapman has demonstrated a keen ability to develop unique solutions to complex problems.

Latest Patents

Chapman's latest patents include an "Apparatus for generating lobular polygonal forms" and a "Thread forming fastener." The apparatus for generating lobular polygonal forms comprises a first device rotatable about an axis, a second device including a member eccentric to the axis and movable in an orbit thereabout, and a third device responsive to the combined movement of the first and second device for tracing a lobular polygonal form. This form can maintain approximate tangency with two parallel planes or three circles of equal diameter upon rotation. The generated lobular form may be traced by a metal-working tool that forms a die cavity in a workpiece, allowing for the creation of a novel lobular screw blank. The thread forming fastener features circumferentially spaced thread-forming lobes, with thread depth varying between maximum and minimum at different regions. This innovative design enhances the efficiency of self-threading fasteners.
