Patents by Inventor Doyle D. Hendrickson

Doyle D. Hendrickson 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).

  • Publication number: 20040203332
    Abstract: A cutting instrument is provided which includes a frame member, a blade body member, a blade element, an acute angle end point, a pivot element and a blade retention cavity. The body member can provide a blade element which is concave and through which a lifting edge which cuts and a retention edge which cuts can both combine to provide a centering feature. This centering feature can be enhanced by blade body designs which also center through the use of an offset concave element. The frame member can include a thumb rest as well as a rotational restraining element which are diametrically opposed and which can present roughly orthogonal forces.
    Type: Application

  • Patent number: 6722969
    Abstract: A precision micro taxidermy cutting instrument is provided which includes a single hold tailless frame member to which a pivotable body member is attached. The body member can provide a blade element which is concave and through which a lifting edge which cuts and a retention edge which cuts can both combine to provide a centering feature. This centering feature can be enhanced by blade body designs which also center through the use of an offset concave element. A chisel element can separate the hide from the viscera and through the selection of appropriate angles and the like, a continuous and precise cut can be made in taxidermy operations. The frame member can include a thumb rest as well as a rotational restraining element which are diametrically opposed and which can present roughly orthogonal forces. Flared separators can be included on the blade body member to further enhance the operation of the device.

  • Patent number: 6471577
    Abstract: A precision micro taxidermy cutting instrument can include a single hole tailless frame member, a pivotable body member, a concave blade element, a lifting edge and a retention edge with a centering feature enhanced by blade body designs which also center through the use of an offset concave element. A chisel element can separate the hide from the viscera and through the selection of appropriate angles and the like, a continuous and precise cut can be made in taxidermy operations. The frame member can include a thumb rest and a rotational restraining element which are diametrically opposed and which can present roughly orthogonal forces. Flared separators and releasable locking mechanisms may also be included.
