Abstract: A first cup member (4) has (a) a first channel (18) which passes radially from the center of its bottom panel (6) along the inside surface of said bottom panel (6) and substantially axially, upwardly along the inside of its wall(s) (8) and (b) an outlet (16) which communicates with the first channel (18) at a point remote from said bottom panel (6). A second cup member (10) has an opening (20) in its bottom panel (12) at an edge of the bottom panel (12) which communicates with a second channel (22) which passes radially along the outside surface of its bottom panel (12). The second cup member (10) is positionable within the first cup member (4) for moving the opening (20) to the lowest point in the second cup member (10).

Abstract: A nozzle, for use in a gas-operated spraying apparatus such as an airbrush, is disclosed. The nozzle locates concentrically within an air cap in the gas outlet of a spraying apparatus and cooperates with a tapered needle located in an axial passage thereof to seal the outlet of the nozzle. The needle is retractable in the nozzle to dispense a medium such as paint to be sprayed.

Abstract: A control mechanism is provided for use in a gas-operated spraying apparatus such as an airbrush having a needle located axially of a nozzle, the needle being retractable in the nozzle to dispense a medium, for example, paint to be sprayed. The control mechanism includes a manually actuated operating member supported by a pivotal linkage and movable in a first manner to retract the needle, the pivotal linkage causing the needle to be retracted initially at a reduced rate.
