SPRAY GUN MOUNT AND RETROFIT KIT

摘要

A spray gun mount, and retrofit kit spray gun mount based thereon, and a method of retrofitting, adjusting and spraying based thereon, are structured that the motion of the spray gun occurs about a point of rotation located at the exact nozzle of the spray gun rather than at a location on the gun mount. An arcuate slot may be provided on a fixed mounting plate and extensions (partially threaded screws) pass through the arcuate slot. The extensions in turn are firmly attached to a movable gun mount plate to which the spray gun is affixed. In adjusting the spray gun, all that may be necessary is to loosen a fastener which holds the gun mount plate and gun from rotating relative to the fixed plate, rotating it relative to the fixed plate and fastening it back into place again.

主权项

1. A sprayer for coating the inner surface of a cylindrical item of manufacture, the sprayer comprising:
a generally cylindrical spray gun barrel having a first nozzle end and a second rear end to receive a coating such as lacquer, the spray gun barrel having a longitudinal axis, a first extension projecting from the spray gun barrel; the length of the longitudinal axis from the nozzle end to the first extension being L; a first slot, the first slot generally arc shaped, the arc of the first slot defining a plane P of the arc, the arc shaped slot defining a focus F of the arc lying in the plane P of the arc, the arc radius R being equal to L; the first extension passing through the first slot, and the longitudinal axis of the spray gun held parallel to the plane P of the arc at an offset distance O, whereby the nozzle end may be held orthogonally offset from the focus F in the plane P by the distance O; a fastener dimensioned and configured to physically engage the spray gun and in a first (secured) mode hold the spray gun barrel extension locked in place in the first slot whereby the spray gun barrel is held in an alignment with the first slot and the nozzle end is held in place; the fastener dimensioned and configured to, in a second (free) mode, allow the spray gun extension to travel within the first slot, whereby the spray gun barrel alignment with the first slot may change but the spray gun nozzle remains held in place while the rear end of the spray gun barrel sweeps through an angle σ.
