Joseph V. Matucheski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Lubricant flow suppressor
    Patent number: 9033108
    Abstract: A lubricant flow suppressor positioned proximate a rotating component for receiving ejected lubricant therefrom and reducing the kinetic energy of the ejected lubricant. The suppressor includes at least two perforated walls with a lubricant flow path formed therebetween.

  • Fan spider with rake angle
    Patent number: 4242046
    Abstract: A sheet metal construction for a fan spider. The spider arms each carry an integral rib running centrally along the arm and each rib is flat on its upper surface to mount a fan blade. The novelty of the invention resides in canting forwardly the spider arms. Such canting reduces certain stresses in the fan, thereby reducing cost of manufacture.

  • Flexible bladed fan construction
    Patent number: 4172693
    Abstract: A flexible fan blade construction of the type wherein a decamber limiter is carried by each spider arm and bears against one side of its associated fan blade to thereby limit flexing (decamber) thereof. According to this invention, the decamber limiter terminates short of the heel of each fan blade. High stress concentrations due to contact between the heel edge of each fan blade and its associated decamber limiter are avoided by this novel construction.

  • Radiator cooling fan construction
    Patent number: 4150919
    Abstract: A fan construction of the type having a hoop configured hub provided with fan blades. The hub has apertures adjacent the blade roots. A viscous drive carries the hub. Rotation of the fan causes a pressure differential between the two ends of each hub aperture thus forcing an airflow radially outward to assist in cooling the viscous drive.
