Donald E. Wetzel 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: 8422716
    Abstract: A telescoping boom pole for an electrical conductor is disclosed. The boom pole includes at least a top cylindrical conduit slidably assembled within a second cylindrical conduit. A top clamping means is included for selectively clamping the top conduit to the second conduit. The top clamping means includes an annular cylindrical collar having a threaded portion proximate a bottom edge on an inside surface thereof, and a collet restraining means proximate a top edge thereof. An annular, compressible collet is resiliently captured by the collet restraining means of the collar at a cooperative restraining means of an outside surface of the collet. The collet further includes an inclined lower portion on an outside surface thereof. The top clamping means further includes an annular sleeve fixed to a top end of the second conduit, and has an outside surface that includes a threaded portion that cooperates with the threaded portion of the collar.

  • Patent number: 5579071
    Abstract: A camera stabilizing support apparatus includes motorized "x-y translation" of one or more components of the camera equipment, such that no mechanical forces are imparted to the overall system which would adversely affect the angular position of the gimbaled mass, synchronous control of the motion of lower masses of the camera stabilizing support apparatus so that both dynamic and static balance is preserved throughout the range of motion, and an adjustable gimbal mechanism which serves to isolate the system's equipment support from the support arm extending from the operator's body harness which provides both coarse and fine location adjustment, and provides positive self-centering for these gimbal locking elements so that no clamp distortion occurs.

  • Patent number: 5435515
    Abstract: The support arm of a camera stabilizing device is provided with a tensioning assembly which is mated to the support arm in a fashion which permits continuous adjustment of the geometric relationship between the end points of the tensioning assembly and the remaining structures which comprise the support arm. This can include adjustment of the frame of the support arm, or adjustment of an end point of the tensioning assembly relative to the frame of the support arm using a cable and drum arrangement coupled with a spring of appropriate size and tension.
