Publication number: 20140377470Abstract: An apparatus and method provide an adjustable, aimed, lighting system that may be selectively secured to and removed from the ferrule of a paintbrush for illuminating the edge of the bristles during a cutting-in process. The light may be moved as appropriate, and may be aimed to ride with the brush, thus illuminating directly at the edge where paint is being deposited. Thus, precise deposition of paint may be done in spite of the shadows cast by the body of the painter and the bulk of the brush during much of such cutting-in procedures.Type: ApplicationFiled: February 20, 2014Publication date: December 25, 2014Inventor: John D.

Patent number: 4756374Abstract: A device (10) for providing an indication of loads exerted on a vehicle frame (12) comprises a sensing unit (22) mounted to and between the frame (12) and the vehicle axle (14) and for detecting vertical displacement of the frame (12) relative to the axle (14) when loads are exerted on the frame (12). The sensing unit (22) comprises an arm (126) pivotally mounted to the frame (12), through a pair of telescoping tubes (32, 44), and an adjustment rod (124) movably mounted to and between the arm (126) and the axle (14). When a load is exerted on the frame (12), the same depresses relative to the axle (14) and the arm (124) rotates. Rotational movement of the arm (124) is measured by a clinometer (128) mounted thereto and which converts the angular measurement into a coherent digital or analogue readout displayed by a receiving unit (26).Type: GrantFiled: March 31, 1987Date of Patent: July 12, 1988Inventors: John D.
