ABSTRACT:
An automatic powder dispenser for the handles of tennis rackets and the like is disclosed herein which comprises a chamber within the handle and several passageways which connect the chamber with the exterior of the handle. A relatively fine powder of rosin, corn starch, magnesium carbonate, and similar materials is contained within a foraminous cartridge located within the chamber. The particle size of the powder material is less than the size of the openings in the foraminous cartridge and the passageways connecting the chamber to the exterior of the handle. Movement of the handle will therefore result in the powder being dispensed by the cartridge to the chamber and through the connecting passageways to the exterior of the handle. A cap or similar closure is removably received in an exterior opening in said chamber to permit the cartridge to be removed from the chamber. A cylinder having apertures located in the same pattern as the pattern of the passageways at the chamber wall may be included to fit snugly against the interior wall of the chamber. Rotation of the cylinder relative the interior wall of the chamber thereby provides a means for closing the passageways at this location to prevent the powder from being dispensed through the apertures.
