Abstract

Abstract A convenient and efficient paint tank which utilizes water pressure as the pressure means for dispensing paint from the tank through the application device. More specifically a paint tank having an upper and lower chamber separated by a flexible diaphram. Paint and the like is introduced into the upper chamber by way of an access port and water is introduced into the lower chamber by a hose. The water induces a pressure against the diaphram forcing the paint out of the upper chamber and through a valve to the application device. Further, a way of introducing water into the upper chamber is also provided such that the tank will clean itself when the paint has been removed.

Claim 2
Dependent Claim 69 words
A paint container for dispensing paint through a hose to an application device comprising: a. An upper chamber having at least one valve; b. A lower chamber attached to said upper chamber; c. A flexible diaphram attached between said upper and lower chamber; d. Means for introducing water into said lower chamber, and e. means for introducing water from said lower chamber about the upper surface of said chamber.
Claim 3
Dependent Claim 35 words
a paint container as described in claim 1 wherein said flexible diaphram further comprises: a. A hollow concave center portion; b. A circular rim attached about the perimeter of the edge of said center portion.
Claim 4
Dependent Claim 34 words

Claim 6
Dependent Claim 67 words
a circular plug received by said port, 2. a frame having a plurality of arms, 3. a plurality of hooks at the end of said arms for engaging said rods, and 4. a hand operated set screw central of said frame for contact against said plug, whereby said set screw may be screwed down with said hooks engaging said rods thereby applying sealing pressure against said plug.
Claim 7
Dependent Claim 67 words
a circular plug received by said port, 2. a frame having a plurality of arms, 3. a plurality of hooks at the end of said arms for engaging said rods, and 4. a hand operated set screw central of said frame for contact against said plug, whereby said set screw may be screwed down with said hooks engaging said rods thereby applying sealing pressure against said plug.
