Abstract: A rotary motion powered system for energizing light emitting diodes is taught that utilizes a permanent magnet generator (20) located within a vehicle wheel (64) for producing the requisite electric power. The generator consists of two main elements: a rotating portion (26) and a stationary portion (28). The rotating portion utilizes a base (30) that is attached directly to an adapter base (72) attached to the vehicle wheel, and the stationary portion includes a counter weight (62), thus permitting this portion to remain horizontal when the wheel is rotating. An ac/dc bridge rectifier (22) is in electrical communication with the generator output to change the alternating current produced by the permanent magnet generator to direct current. A number of light emitting diodes are disposed within a vehicle wheel member and are powered by the direct current power, thereby producing an unusual and unique visual effect when the wheel is rotating.

Abstract: A collapsible cross-arm dolly for conveyance of weighted articles. The dolly consists of an upper arm (20) and a lower arm (24) of square metallic tubing, with each formed with a horizontal offset center portion (22) and (26) and with a pair of casters (30) that are attached at each end of both arm's lower surface. The horizontal offset center portion (22) is formed in opposite hand or mirror image of each other, thus permitting them to nest together and are both oppositely flattened to allow nesting on the same horizontal plane. A pivot junction (32) is mutually disposed between the arms, thereby permitting the dolly to form a pivotal right angle cross position (36), or alternatively, a pivotal parallel arm collapsed position (38). A gravity-actuated restraint (50) locks and disengages the connection of the upper arm to the lower arm, which permits changing orientation from the right angle cross position (36) to the parallel arm collapsed position (36).

Abstract: A universal pipe joint for attaching two round pipes together accommodating misalignment using a female adapter fitting (30) engaging a male adapter fitting (44), each having a radial interior and exterior diameter (38) and (50) with a compression nut (52) urging them together. The female fitting has external threads (40) with a number of locking grooves (42) at right angles to the threads, and a compression nut with a spring-loaded ball (54) therein that clicks into the grooves while the nut is being tightened. When the nut is fully tightened, the radial diameters are compressed and the ball (62) is locked into the groove with a set screw (66). Thus securing the connection and eliminating loosening by over the road operation of a vehicle to which the device is attached. A second embodiment replaces the compression nut with a pair of flanges (68) held together by nuts and bolts.

Abstract: An improved motor vehicle brake-pedal locking device (10) that mechanically maintains the vehicle brake-pedal (60) in a depressed position to prevent the vehicle from being driven. The device includes a horizontally and vertically pivoting brake-pedal swing-arm interfacing structure (12) that is disclosed in two designs. Both designs include a channel (12A),(38C) that engages the brake-pedal swing-arm (62). To the back end (18B),(34B) of the structure (12) is attached the back end (50B of a locking tube (50). Inserted into this locking tube (50), is a locking rod (52) having attached to its back end (52B) a forked section (56A) that attaches to a vehicle seat (64). The device is installed by placing the structure (12) over the swing-arm (62) and the forked section (56A) secured to the seat (64). The device (10) is then depressed to place the brake-pedal (60) in a depressed position in which position the device is locked in place.
