Self-contained portable pressure apparatus and hand gun assembly

A portable, self-contained pressure apparatus readily carried around by hand to the location of operation and supported primarily by the back of a user when in operation, said apparatus comprising, in combination:

• a pressurized tank,
• a backpack carrier adapted to be releasably mounted on the back of a person, said carrier having a tank support frame and releasable tank fastening means on the support frame for releasably fastening the pressurized tank to the support frame, said carrier having a pair of laterally spaced, generally arcuate rigid shoulder straps attached at one end to an upper portion of said upright portion extending out away and then down therefrom to mount the tank support frame on the shoulders of the user and to dispose said support frame and tank at an angle of inclination with the tank outlet and at an elevated position in a demounted at rest position.
• handle means for hand carrying the backpack carrier and tank to a point of use, said handle means including a C-clamp portion surrounding the tank positioned and centered about the midpoint between the top and bottom of the tank, releasable fastening means holding the C-clamp portion on the tank and a handle grip portion affixed to and disposed a distance away from said C-clamp portion,
• a line pressure control and coupling means coupled to said tank to regulate the amount of air pressure from said tank to a pressure responsive load device, and
• a pressure driven spray gun coupled to the output of said line pressure control and coupling means, said spray gun being a pattern spray gun for spraying a fluent texture coating material on walls and the like, said spray gun having a feed hopper for storing a batch of fluent texture coating material and delivering said material to the spray gun which selectively sprays the material in response to air pressure from said line pressure control and coupling means.
