Latest Patents

Among his latest inventions is the "Driving Sprocket for Conveyor Chain on Finger Jointing Machines." This innovative sprocket is designed to drive the conveyor chain on finger jointing machines, featuring a base plate with a central aperture. The design includes drive hubs mounted on the base plate's opposed faces, which are rotated by conventional power transmission equipment. The drive hubs project into the central aperture, with clutch plates interposed in an operative series relation between the drive hub and the base plate. This mechanism allows for solid and direct driving of the clutch plates, which in turn frictionally drive the base plate. Caliper clutch assemblies are utilized to control the level of frictional engagement between the clutch plates and the base plate.

Another significant patent is the "Adjustable Prosthetic Foot." This invention allows for the adjustment of heel height in a prosthetic foot. It features a cavity at the rear aspect of the foot that accommodates a separate locking block. Both the locking block and the cavity are arcuate in configuration, with a pair of arcuate rails secured to the lower aspect of the block. These rails are designed to fit into complementary grooves on the upper surface of the cavity, allowing for longitudinal and arcuate movement to adjust the heel height. A locking bolt secures the foot to the device, maintaining the desired heel height.
