Latest Patents
One of Walker's latest patents is a method and device for locking cylindrical members together. This invention features a wire lock designed to hold a stop ring on the outer surface of a cylinder. The stop ring includes a counterbore positioned above an annular groove in the cylinder's outer circumference. The wire lock is inserted into the registered counterbore and annular groove, preventing the stop ring from moving axially on the cylinder's surface. The wire lock remains accessible and visible from one axial end of the stop ring.
Another significant patent by Walker is a piston locking device for double acting hydraulic cylinders. This invention utilizes a unique fastening mechanism that secures the piston to the cylinder rod. The piston has a rod receiving opening through which the piston rod is fitted. It includes a piston groove aligned with an annular rod groove on the rod's outer surface. An access opening extends from the piston’s outer circumference inwardly to the piston groove, allowing a retaining wire to be inserted. This wire wraps around the piston rod and fits within both grooves, effectively holding the piston against longitudinal movement with respect to the rod.
