Latest Patents

Among his latest patents, the "Fan spider with rake angle" stands out. This invention features a sheet metal construction for a fan spider, where the spider arms each carry an integral rib running centrally along the arm. The upper surface of each rib is flat, allowing for the mounting of a fan blade. The novelty of this design lies in the forward canting of the spider arms, which reduces certain stresses in the fan, ultimately lowering manufacturing costs. Another significant patent is the "Flexible bladed fan construction." This design incorporates a decamber limiter carried by each spider arm, which bears against one side of its associated fan blade to limit flexing. Notably, the decamber limiter terminates short of the heel of each fan blade, preventing high-stress concentrations that could arise from contact with the heel edge.
