Latest Patents
David holds a patent for a Coupling Shock Resistant (CSR) Coupler. This invention features a shock-resistant coupler designed for vehicles, which includes a substantially hollow draft gear tube and a coupler head. The draft gear tube has an inside surface, while the coupler head possesses a flexible, substantially hollow shank portion. The shank portion extends into one end of the draft gear tube, and a collar on the distal end features a predetermined number of longitudinally extending relief grooves. The design incorporates at least two slots that allow the shank portion to be compressed inwardly for insertion into the draft gear tube. A plurality of shear bolts secures the shank portion against the inside surface of the draft gear tube, ensuring a robust connection. The mouth of the draft gear tube is internally threaded, allowing for an exteriorly threaded ring or bushing to be secured, preventing the coupler head from being pulled from the draft gear tube.
