Abstract: A housing has five sockets extending beyond the front face thereof, spaced to simultaneously engage the lug nuts securing a wheel to a vehicle. Each socket has secured to a peripheral portion a satellite gear that engages a universal gear. The universal gear has a drive surface allowing it to be driven in a conventionally opposite direction to simultaneously remove the lug nuts and then driven in the opposite rotational direction by a pneumatic wrench to simultaneously secure the lug nuts securing the replacement wheel to the vehicle, greatly reducing the time needed for a wheel/tire change. This tool has the potential for greatly reducing the time required for a pit stop in stock car racing giving a huge advantage to the team so equipped.

Abstract: Skates having increased lateral stability for use in speed skating and hockey. A primary blade is provided with first and second secondary blades which extend laterally outwardly from the primary blade at angles therefrom. In a first preferred embodiment, these secondary blades extend outwardly at equal 45° angles and engage the surface of the ice when the primary blade tilts either direction through an angle of 45°. In a second preferred embodiment, the inner secondary blade extends outwardly at a lesser angle of say 30° so that double blade engagement of the ice can be more easily accomplished for sprinting situations.
