This invention pertains to the maintenance of pressure within a vehicle wheel tire to a pre-set level with the air supply being produced by a pump which is driven by centrifugal force, i.e., the wheel rotation creates a centrifugal force which activates a weight to move a piston which pumps the tire inlet air. The pump can be mounted outside or inside the tire volume. Another pump uses the impetus from bumps encountered by the wheel to drive the pump.

Wheel-mounted tire inflator

A manually operated dispensing tool for repeatedly dispensing a predetermined quantity of pelletized material below the surface of the earth. The tool includes an upright elongated outer housing adapted to be connected with a supply of pelletized material filling a reservoir formed by the outer housing. A spring biased downward sleeve having wall ports is vertically reciprocable in the depending end portion of the outer housing for communicating with the material reservoir. A drop tube of smaller diameter than the sleeve depends from and is secured at its upper end portion in the sleeve below the position of the sleeve ports. A handle assembly, overlying the top of the outer housing, is connected with a stem assembly projecting through the housing and drop tube. A central portion of the stem assembly forms a valve normally closing the upper end of the drop tube to define a measuring chamber in the sleeve communicating with the sleeve ports. The depending end of the stem assembly defines an earth penetrating tip normally closing the lower limit of the drop tube. Downward movement of the device into the surface of the earth moves the sleeve upwardly within the outer housing to uncover the sleeve ports and load the measuring chamber. Manually lifting the stem assembly relative to the housing releases the measured charge of pelletized material to fall by gravity through the drop tube.
