Abstract
Abstract A portable power operated spray apparatus in which a generally cylindrical tank is supported on a saddle including a flat base and upstanding end plates shaped to receive the cylindrical side wall of the tank. Straps are welded to the end plates and extend around the tank and have upturned ends at the top of the tank spaced apart and connected by a tie bolt to provide carrying handles for the spray apparatus. An electric motor-pump unit is mounted on the base below the tank and arranged to be operated from a vehicle electrical power system to deliver chemicals from the tank through a flexible hose to a spray head.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
279 words
A portable power operated chemical spray apparatus for use with a motor vehicle having a vehicle electrical power system, the spray apparatus comprising a generally cylindrical supply tank, a tank cradle including a generally flat base plate having a length less than the length of the tank and upstanding end plates adjacent opposite ends of the base plate each having a concave upper edge shaped to receive the cylindrical side wall of the tank, a pair of generally circular metal straps each secured to the upper edge of a respective one of the end plates, each strap extending around the cylindrical side wall of the tank at locations spaced inwardly of the ends of the tank and having upturned end portions adjacent the top of the tank spaced apart a distance sufficient to receive a hand therebetween, strap end connector means extending between the upturned end portions of each strap at a position spaced above the tank for interconnecting the upturned end portions on each strap in spaced relation to each other and providing handle therebetween, a pump having an electric drive motor mounted on the upper side of said base plate inwardly of the periphery thereof and adjacent the underside of the tank and having a pump inlet and a pump outlet, means connecting the pump inlet to the tank, an elongated flexible spray hose, first hose connector means connecting one end of the spray hose to the pump outlet, a spray head means and second hose connector means connecting the other end of the hose to the spray head, and means for electrically connecting the electric drive motor to the vehicle electrical pump system for energization thereby.

Claim 3
Dependent Claim
53 words
A portable spray apparatus according to claim 1 wherein said strap end connector means includes a tubular handle member disposed between the upright end portions of each strap and tie bolts each extending through the upright end portions on a respective one of the straps and through the tubular handle member disposed therebetween.
Claim 4
Dependent Claim
85 words
A portable spray apparatus according to claim 1 wherein said first and second hose connector means includes first and second like female hose coupling members at opposite ends of the spray hose, a first male hose coupling member connected to the pump outlet and a second male coupling member connected to the spray head means, and first and second filter screens in the first and second female hose coupling members whereby the hose can be reversibly connected to the pump outlet for cleaning the screens.
