摘要：An automatic powder dispenser for the handles of tennis rackets and the like isdisclosed herein which comprises a chamber within the handle and several passagewayswhich connect the chamber with the exterior of the handle. A relatively fine powder ofrosin, corn starch, magnesium carbonate, and similar materials is contained within aforaminous cartridge located within the chamber. The particle size of the powdermaterial is less than the size of the openings in the foraminous cartridge and thepassageways connecting the chamber to the exterior of the handle. Movement of thehandle will therefore result in the powder being dispensed by the cartridge to thechamber and through the connecting passageways to the exterior of the handle. A cap orsimilar closure is removably received in an exterior opening in said chamber to permit thecartridge to be removed from the chamber. A cylinder having apertures located in thesame pattern as the pattern of the passageways at the chamber wall may be included tofit snugly against the interior wall of the chamber. Rotation of the cylinder relative theinterior wall of the chamber thereby provides a means for closing the passageways atthis location to prevent the powder from being dispensed through the apertures.
