Lyndell J. C. George 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).

  • Self-leveling construction alignment laser
    Patent number: 4119382
    Abstract: The specification discloses an improved system for projecting and utilizing a light beam as a reference line for construction purposes. The system includes a light beam projection device mounted in a housing. A light path compensator is positioned within the housing and intercepts the beam of light emitted by the light beam projecting device and automatically corrects slight deviations of the light beam from true horizontal. A vertically adjustable leg is attached to the front end of the housing and a horizontally pivotable leg is attached to each side of the housing near the rear end of the housing to enable leveling and centering of the housing in a conduit or positioning and leveling on any surface. Structure is controllable from the rear of the housing to deflect the light beam in a vertical plane to vary the grade of the beam projected by the device. An indicator, readable from the rear of the housing, is provided for indicating the grade at which the light beam is projected.
    Type: Grant
