ABSTRACT:
A powder dispensing device which includes an indexing motor for incrementally rotating a flexible rotor wheel fitted with a plurality of spaced apart, open ended metering chambers. The device is designed to allow the metering chamber to fill with powder while rotating within a powder reservoir and to selectively register with a peripherally sealable tubular outlet through which the powder collected therein can be pneumatically ejected. The indexing motor includes a sectored drive gear loosely held about an elongated shaft fixed at its lower end to a pin wheel having a number of spaced apart bored openings. The bored openings hold a plurality of vertically slidable pins which selectively engage the sectored drive gear. A pneumatic piston cooperatively connected to a tooth-rack gear is provided for moving the sectored drive gear incrementally.
