Latest Patents

One of his latest patents is the "Interlinking mechanism for multiple carburetor system." This invention features a throttle valve synchronizing arrangement for the induction system of a V-type engine. The throttle valves associated with each cylinder bank rotate in common vertical planes that are not parallel or collinear with each other. The throttle valve shafts are staggered, and a linkage system synchronizes the throttle valves of each bank. Additionally, the banks are synchronized with respect to each other through an intermediate shaft positioned at a greater angle to the throttle valve shafts.

Another significant patent is the "Assist device for shift operation of marine propulsion system." This invention presents an improved shift assist mechanism for a marine propulsion transmission. It includes a pivotally supported shift assist element that defines a slot for receiving a member of the linkage connecting the shift operator with the shift control element. The mechanism allows for smoother transitions between forward and reverse drive positions by reducing engine speed during shifting.
