Abstract: An apparatus and method for preparing a skateboard useful in performing tricks requiring a high degree of tilt. In one embodiment, the present invention involves disposing a riser pad between the deck and the truck assembly unit of a skateboard, attaching a truck assembly unit to a deck having a top surface and a bottom surface. The riser pad is a planar member comprising material selected from the group consisting of rubber, plastic, metal alloy, and combinations thereof. The planar member has four elongated holes disposed therein, through which fasteners for attaching the truck assembly unit can pass.

Abstract: Apparatus for securing a wheelchair to the floor of a vehicle or the like comprises two pairs of clamp posts journaled for up and down movement. Each post has a pair of clamp jaw members positioned to engage the wheelchair underframe. A main piston raises and lowers the posts simultaneously. Each post has a pair of clamp jaw pistons operatively connected to the corresponding clamp jaw members to grip the underframe. A control circuit comprises an electrical-motor-operated pump, a four-way solenoid-operated direction control spool valve, a pair of sequence valves, pilot operated check valves in the pressure lines leading to the clamp jaw pistons, and a three-way electrical toggle switch having "UP", "DOWN" and "OFF" modes. In "UP" mode the main piston lifts the clamp posts to and optionally beyond a position to engage the frame where one of the sequence valves directs pressure fluid to the clamp jaw pistons to lock the clamp jaws onto the frame.

Abstract: Portable swaging tool for affixing a battery terminal onto an electrically conducting cable, such as for the starting motor of an internal combustion engine, especially with the cable already installed in the confined space of a vehicle engine compartment. Portions of a short handle member and a pivoted clamping member have cooperating jaws to receive a battery terminal between them. The handle member carries clamping means adapted to engage the clamping member to force the jaws together sufficiently to swage a terminal onto a cable end inserted into a bore in the terminal.

Abstract: A portable swaging tool for affixing, onto the end of an electrical cable, a terminal of the type that fits on the terminal post of an electrical storage battery such as may be used to drive the starting motor of an internal combustion engine. A handle carrying one of a pair of cooperating jaws has pivoted to it a clamping member carrying the other cooperating jaw so as to be juxtaposed to the first jaw when the free end of the clamping member is swung to and against the handle. The handle also carries clamping screw means for forcing the clamping member against the handle to clamp a terminal pre-inserted between the jaws and to swage the terminal tightly onto the end of a battery cable pre-inserted into a bore in the terminal.
