Abstract: An elongated bar with a threaded central aperture has a laterally spaced unthreaded oval slot on each side of the aperture. A threaded side rod extends through each oval slot with threaded jam nuts on each side of the bar. A central rod has a threaded central extent received in the aperture. The upper end of the rod has a head to facilitate turning the rod within the bar and the axial movement there between. The lower end is formed with an axial slot and a radial hole. A pivoting wing locking plate has a pivot pin rotatably coupling the locking plate to the rod. The locking plate is positionable in contact with a side of a wheel remote from the bar. A radius plate secured to the lower end of each side rod has a lower face positionable in contact with a side of a tire adjacent to the bar.

Abstract: A right angle ratchet wrench drive unit comprised of a drive unit formed in an L-shaped orientation. The drive unit has a first end and a second end each having recesses. Each recess has an axis positioned at a ninety degree angle with respect to each other. The second recess has an internal cylindrical recess extending coaxially inwardly of its inboard end. The internal cylindrical recess has a pair of diametrically opposed spring-biased detents therein. First and second gear assemblies are positioned within the recesses. Each gear assembly includes a bevel gear having teeth and a central shaft. Each central shaft is formed in a generally cylindrical configuration with an inner end and an outer end. The outer end of the central shaft of the second gear assembly has a shoulder portion disposed thereon. The shoulder portion has a gear post extending coaxially therefrom. The bevel gear of the second gear assembly is positioned around the gear post.

Abstract: A connector (40) for insertion into a portable electronic device (30) provides testing, programming and power thereto. The portable electronic device (30) has a chassis (32) housed therein and further includes a battery cavity (35) with battery contacts (36) therein. The connector (40) has a distal end for contacting the chassis (32) through an access port (34) in the battery cavity (35). A proximal end of the connector (40) is adapted for connection to a cable. The connector (40) has a substrate (50) attached to a printed wire board (41), wherein the printed wire board (41) further comprises a first plurality of conductors (52) thereon for receiving data signals from the cable, and a second plurality of conductors (42) thereon for receiving power signals from the cable.

Abstract: An oil well tool retrieving device in the form of a jar is provided having a hollow casing including a downwardly facing impact surface, a hammer of cylindrical construction slidably engaging an inner surface of the casing and impacting with the impact surface in one direction and an upwardly facing casing impact surface in the other, a mandrel of cylindrical construction from which the hammer is supported slidably engaging an inner surface of the casing, a double track raceway formed in and extending along a length of the mandrel, resiliently mounted bearing elements supported from the casing and for engaging the double track raceway and a hump element mounted in one of the tracks of the double track raceway while the other track is a free raceway.
