Purge method and apparatus for a manual spray gun or coating material application device, in which purge air is introduced into the device through a handgrip portion that is manually held during a coating operation. Purge air first enters the coating material flow path after the purge air enters the handgrip portion.

Apparatus and methods for purging material application device

Nozzle

A nozzle for a powder spray gun optionally includes an internal filter that allows air to be added to the powder flow within the nozzle shell. The nozzle may optionally include an off-axis outlet slot relative to a main flow axis of the powder into the nozzle shell so that powder encounters an obstruction before exiting through the outlet slot.

Powder coating system and components

Powder charge sleeve

An annular thread cutting die head for a power driven threading machine is comprised of an annular support plate assembly supporting a plurality of radially displaceable threading cutting dies spaced apart about the axis of the die head, and a cam plate assembly coaxial with and pivotal relative to the support plate assembly to radially displace the cutting dies. The cam plate assembly is spring biased to pivot relative to the support plate assembly in the direction to radially retract the cutting dies, and pivoting in the latter direction is controlled by a keeper mounted on the support plate assembly and engaging a keeper track on the cam plate assembly. The keeper is mounted on the support plate assembly for pivotal displacement about a keeper axis parallel to the die head axis, and pivotal displacement of the keeper is controlled by a lever mechanism actuated by a workpiece being threaded to provide for progressive displacement of the cam plate assembly and receding displacement of the cutting dies during the threading operation.

A rotatable chuck for supporting a plastic coated workpiece in a power driven threading machine is disclosed comprising workpiece engaging jaws mounted on the machine spindle for rotation therewith and for pivotal movement relative thereto radially inwardly and outwardly of the spindle axis. Each jaw pivotally supports an insert holder provided with a pair of inserts for engaging the outer surface of the workpiece. Each of the insert holders pivotally supports a centering link associated with an adjacent jaw so as to be actuated in response to pivotal displacement of the jaws radially inwardly of the spindle axis to control the attitude of the insert holders so that the inserts are directed radially inwardly of the spindle axis to assure a uniform gripping action by the two inserts of each holder upon engagement with the workpiece. The centering links also displace the workpiece to a centered position coaxial with the spindle axis during inward displacement of the jaws.
