DEFINITION

Classification: 222/367

(under subclass 344) Dispensers in which the movable trap chamber element is of the conveyor type and has a motion of rotation about its own axis or plural trap chambers are assembled to rotate about a common axis.

(1) Note. The trap chamber element has a generally circular periphery and may have one or more pockets, the axis being the center of the unit as a whole.

138+, for combinations involving plural sources, compartments, or receptacles.

167+, for rotatable supply receptacles.

216+, for combinations with an agitator or ejector to remove material from the supply container. 233+, and 236+, for combinations with a precedent, serially arranged agitator.

264, and 271+, for plural such devices.

282+, for combinations with discharge volume varying means, particularly 293+.

336+, for combinations with biasing means.

356+, for dipping trap chamber type which are nonrotary.

360, for rotary devices having a relatively movable actuator for imparting intermittent motion.

362+, where means are provided to require oscillation.

410+, for rotary discharge assistants not of the trap chamber type.

452, for rigidly connected rotary valves for controlling the inlet and outlet of a trap chamber, but not forming a complete enclosure for the trapped material, so as to constitute a conveyor type trap chamber.

548+, and see the notes thereto for rotary closures.
