Corey J. Hemman 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).

  • Patent number: 8651452
    Abstract: A valve having an improved multiple position notch plate providing a large number of selectable valve positions with enhanced strength, including in the travel stop limiting the range of movement of the valve handle connected to the valve member. The notch plate includes a plurality of intermediate notches extending only partially through a radial outer periphery thereof, at spaced locations along an arcuate path of movement of a detent element in connection with the valve handle. In one embodiment, the intermediate notches are disposed in radial outer tips of fingers defining a plurality of through notches extending completely through the notch plate, also for receiving the detent element for holding the handle. As a result a greater number of valve positions can be achieved, with robustness and strength to withstand hammer blows, kicking and the like.
    Type: Grant

  • Patent number: 8201852
    Abstract: A coupler for joining a pipe to another pipe, a tee, or other fitting, and more particularly, to a coupler which provides positive retention of the gasket about the circumference of the coupler sufficiently to precisely position and hold the gasket during placement about pipe ends and/or fittings to be coupled, and which provides controlled circumferential compression of the gasket during coupling, for positive sealing when the coupler is closed, while allowing one handed handling and operation during placement and coupling, such that the other hand can be used for supporting a pipe to be coupled, and which is operable for releasing and breaking loose the coupler and associated gasket from a pipe during uncoupling.
