Abstract: An axle is made-up of a left and a right axle halves which axially engage to form a completed axle assemble for supporting a roller skate wheel or other rotating member. A control rod is positioned and enabled for axial translation within the axle and may be moved by physical contact with the rod through an access hole at one end of the axle. A spring normally positions the control rod so that a set of ball bearings mounted within radial holes in the axle are forced into outward positions for engaging the axle halves to form a unitary unit. When the control rod is translated against spring tension, however, the bearings are able to move radially inwardly so as to disengage the axle halves for quick disassembly for replacing a wheel or other need. The axle provides a spring bias enabled for forcefully separating the axle halves once released. A threaded cap is adjustable in its position to moderate the separating force.

Abstract: An oil pump for high performance internal combustion engines suitable for use with race cars and the like wherein extended wear and tolerance maintenance is achieved by supporting the pump gears on shafts extending through the gears. Balanced dual support of the pump gears is achieved by forming bearing openings in the pump lower housing receiving the lower gear shaft portions and lubrication of the lower housing supported gear shafts is achieved by oil passages communicating with the bearings and the lower housing oil outlet cavity. Screw in plugs and retainers are employed to insure effective assembly even under high vibration, and a bolt-on screened oil inlet achieves superior rigidity and ease of replacement.
