This invention is concerned with a coaster for drinking cups comprising:

Coaster

A wheelchair hand propelled by the occupant. Levers on the sides in juxtaposition with the main wheels of the wheelchair are rotatable in the forward-backward direction about the main wheel axle as a fulcrum. A plurality of concentric ratchet rings affixed to each of the main wheels provides engagement for a discrete one of a plurality of pawls associated with each of the levers. The plurality of pawls is distributed progressively circumferentially about a shaft associated with each of the levers, and means are included to rotate the shaft to bring a discrete one of the pawls into operative relationship with a selected one of the concentric ratchet rings, thereby providing a selectable propulsion ratio. The ratchet teeth are oriented such that the pawls slide over them when the levers are pulled backward, but engage firmly when the levers are thrust forward.

Wheelchair with variable ratio propulsion

An air hammer having a main body including an elongated cavity with a ram slidably mounted therein. The ram is driven by compressed air delivered through inlet means to the cavity in such a way as to drive the ram up and down to impact a tool. Exhaust from the hammer is directed into a plurality of elongated expansion chambers which are positioned within the body of the hammer. The expansion chambers extend to each end of the hammer body and exhaust to the atmosphere through open ports. Inserts are placed within the elongated expansion chambers to divide the chambers into properly sized cavities for greatest sound attenuation. Holes extend through these inserts for the eventual passage of exhausting air therethrough. The inserts are of neoprene having a durometer hardness of from 75 to 90. The size of the expansion chambers and the configuration and positioning of the inserts are intended to provide a muffling of the noise and shock of the exhaust. A shut off system is also provided to stop the hammer when it is unloaded.
