Latest Patents
One of his latest patents is the "Shock-absorbing sprocket, drive assembly, and the like." This invention features a shock-absorbing sprocket or gear assembly designed with resilient cushioning means. These means are interposed between mating lugs of the hub and rim to smooth and dampen torsional shocks and vibrations produced by a power drive train. The design includes an improved radial bearing surface that maintains symmetry of the bearing load, ensuring concentricity between the hub and rim. This prevents the rim from wobbling axially or orbiting radially during operation. The cushioning means are configured to accommodate angular displacements of at least 9 degrees. Additionally, a power transmission drive system employing this shock-absorbing sprocket is also described.
Another significant patent is the "Belt sprocket." This sprocket is designed for use with positive drive belts featuring oppositely facing curvilinear driving surfaces. It includes improved symmetrical teeth with a cross-section profile defined by axially oriented, oppositely facing driving surface portions. These surfaces extend from the top land of the tooth at an angle of about 15 degrees or less. Each driving surface blends into an oppositely facing oblique surface at an angle of about 150 to 170 degrees, providing positive clearance between the sprocket tooth and side portions of a meshing belt tooth. This design directs the egress of material away from the sprocket, ensuring efficient operation.
