Abstract
Abstract A pressure spraying apparatus for selectively spraying a cleansing solution, clear rinse water, or a mixture thereof, has a closed fluid-holding tank with a normally closed loading opening. A fluid supply is connected to the tank for replacing fluid as cleansing solution is withdrawn. The incoming fluid is being directed toward a quantity of undissolved detergent in the tank to agitate and dissolve additional detergent to maintain an effective cleansing solution in the tank. A pump and spray device provide a pressure discharge of fluid. The tank supply and discharge line include a bypass and valves for controlling same and pump connections for selectively discharging cleansing solutions or water or mixtures thereof. The tank has a shell extension housing operating equipment, valves and lines mounted for withdrawal for maintenance operations.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
350 words
A pressure spraying apparatus comprising: a. an elongate horizontally disposed shell having a portion closed for holding liquid, said closed portion having a loading opening in an upper portion thereof for placing a soluble detergent therein, b. a removable closure member for closing said loading opening, c. mobile means mounted on said shell for transporting same, d. a power-driven pump mounted within said shell and positioned outside said closed portion, e. water supply conduit means communicating with a lower portion of said closed portion of said shell and connectable to a source of water under pressure for maintaining said closed portion of said shell in a filled condition, said supply conduit means directing the water toward the soluble detergent in the closed portion for agitating the soluble detergent within said closed portion to facilitate the solution thereof to form a cleansing solution, f. liquid discharge conduit means having an inlet in communication with said closed portion of said shell at a point above the soluble detergent, said liquid discharge conduit means being connected to said pump for removing cleansing solution of detergent and water from said closed portion, g. spray means connected to said pump for spraying the cleansing solution, h. said water supply conduit means has an elongate pipe portion positioned within said closed portion of said shell and an elongate flexible tube portion connected to said supply pipe portion, said flexible tube portion being within said shell outside said closed portion, i. said liquid discharge conduit means has an elongate pipe portion positioned within said closed portion of said shell and an elongate flexible tube portion connected to said discharge pipe portion, said flexible tube portion being within said shell outside said closed portion, j. a pair of horizontal elongate guideways within said shell, k. a platform having opposite side edges received within said guideways for longitudinal movement therealong, said platform having said power-driven pump mounted thereon whereby said pump may be withdrawn from said shell, and l. a wall member mounted on one end of said platform for closing said shell when said platform is positioned therein.
Claim 2
Dependent Claim
103 words
The pressuRe spraying apparatus as set forth in claim 2 wherein: a. said pipe portion of said water supply conduit means has one end thereof closed and is positioned adjacent and above a lower surface of said closed portion of said shell; and b. said water supply pipe portion has a plurality of longitudinally spaced apertures in facing relation with the lower surface of the closed portion of said shell whereby jet sprays agitate detergent in excess of that dissolved when said closed portion is filled with water under pressure and said detergent will be dissolved during operation of the pressure spraying apparatus.
Claim 3
Dependent Claim
72 words
The pressure spraying apparatus as set forth in claim 3 including: a. a bypass conduit connecting said flexible tube portions of said water supply conduit means and said liquid discharge conduit means; b. a three-way valve in said bypass conduit for controlling porportions of cleansing solution and water delivered to said spray means; and c. adjustment means exteriorly of said shell and operatively connected to said three-way valve for controlling flow therethrough.
Claim 4
Dependent Claim
208 words
A pressure spraying apparatus comprising: a. an elongate horizontally disposed shell having a portion closed for holding liquid, said closed portion having a loading opening in an upper portion thereof for placing a soluble detergent therein, b. a removable closure member for closing said loading opening, c. mobile means mounted on said shell for transporting same, d. a power-driven pump mounted within said shell and positioned outside said closed portion, e. water supply conduit means communicating with a lower portion of said closed portion of said shell and connectable to a source of water under pressure for maintaining said closed portion of said shell in a filled condition, f. liquid discharge conduit means having an inlet in communication with said closed portion of said shell at a point above the soluble detergent, said liquid discharge conduit means being connected to said pump for removing cleansing solution of detergent and water from said closed portion, g. spray means connected to said pump for spraying the cleansing solution, h. a pair of horizontal elongate guideways within said shell, i. a platform having opposite side edges received within said guideways for longitudinal movement therealong, said platform having said power-driven pump mounted thereon whereby said pump may be withdrawn from said shell.
