Spray rig assembly

Claim 2

A spray rig adapted primarily for roadside spraying from a moving vehicle, comprising an articulated boom assembly mountable on such vehicle within view of an operator on such vehicle, said boom assembly including a boom and a plurality of hydraulic boom position adjusting means coupled to said boom, each boom position adjusting means determining a different range of positions of said boom with respect to surfaces to be sprayed, a spray head assembly, means mounting said spray head assembly at the end of said boom, a source of spray solution, and means for conveying spray solution from said source and delivering it under pressure to both said spray head assembly, and said hydraulic boom position adjusting means, whereby said spray solution is utilized as the hydraulic fluid in said hydraulic boom position adjusting means, thereby eliminating the need for a second power source.

Claim 3

A spray rig in accordance with claim 1, characterized by said hydraulically actuable position adjusting means, each including a cylinder and a piston in said cylinder having a piston rod extending through an end of said cylinder, certain of said position adjusting means having but a single hose line flow-coupled to said cylinder in proximity to an end thereof and others of said position adjusting means having a pair of hose lines flow-coupled to said cylinder, each adjacent a different end thereof, said means for feeding spray solution from said source to said spray head assembly including a hose line and a pump, a control valve in the flow path of said hose line, said means for controlling power to said position adjusting means, each including a valve in the flow path of each of said hose lines to a boom position adjusting means, and said means for assembling all of said control means within convenient reach of an operator on such vehicle, including a housing with said control means installed therein, means coupling each of said hose lines to said housing, means providing a flow passageway from one side of each of said position adjusting means control valves to a different one of said hose lines leading to said position adjusting means, manually actuable means for each of said positioning control valves for selectively actuating said valves to control said plurality of position adjusting means, means for actuating said spray head feed control valve, said actuating means being located in sufficient proximity to said manually actuable means to permit control by arm pressure while said manually means are within reach of the fingers associated with said arm.

Claim 4

A spray rig in accordance with claim 2, characterized by a flow-line from said spray solution supply source to said housing and including said pump, and a flow passageway in said housing flow connecting said flow line to one side of said spray solution feed control valve, and said means for supplying hydraulic power for siad position adjusting means including flow passage means connecting the discharge side of said same pump to each valve of said various position adjusting means.

Claim 5

A spray rig in accordance with claim 1, characterized by means for adjusting the length of said boom, said means including means for controlling said boom length adjusting means, said boom length control means being included with said boom position adjusting control means in said unitary assembly.

Claim 6

A spray rig in accordance with claim 4, characterized by each of said manually actuable means including a substantially vertical lever for each of said position adjusting means control valves, and said arm actuable means for said spray head feed valve including a substantially horizontal lever so located with respect to said vertical levers that when said arm is resting on said subtantially horizontal lever, said vertical levers are within reach of the fingers of the hand associated with said arm.

Claim 7

A spray rig in accordance with claim 1, characterized by said spray solution being of the herbicIde type.

Claim 8

A spray rig adapted primarily for roadside spraying from a moving vehicle, comprising an articulated boom assembly mountable on such vehicle within view of an operator on such vehicle, said boom assembly including a boom and a plurality of boom position adjusting means coupled to said boom, each boom position adjusting means determining a different range of positions of said boom with respect to surfaces to by sprayed, means for supplying power to each of said plurality of boom position adjusting means, means for controlling application of power from said power supply means to each of said position adjusting means, a spray head assembly, means adjustably mounting said spray head assembly at the end of said boom, a source of spray solution, means for conveying spray solution from said source and delivering it under pressure to said spray head assembly, means for controlling flow of spray solution to said spray head assembly and said boom position adjusting means, and means for assembling all of said control means in a unitary assembly within convenient reach of such operator, said means for assembling all of said control means within convenient reach of an operator on such vehicle, including a housing with said control means therein, and a plate affixed to a wall of said housing and extending beyond the bottom thereof, said plate being sufficiently thin to enable insertion thereof into the window slot of a door on such vehicle, to permit removable installation of said housing and included control means on the window sill of such door within convenient reach of an operator occupying a seat adjacent such door.

Claim 9

A spray rig adapted primarily for roadside spraying from a moving vehicle, comprising an articulated boom assembly mountable on such vehicle within view of an operator on such vehicle, said boom assembly including a boom and a plurality of boom position adjusting means coupled to said boom, each boom position adjusting means determining a different range of positions of said boom with respect to surfaces to by sprayed, means for supplying power to each of said plurality of boom position adjusting means, means for controlling application of power from said power supply means to each of said position adjusting means, a spray head assembly, means adjustably mounting said spray head assembly at the end of said boom, a source of spray solution, means for conveying spray solution from said source and delivering it under pressure to said spray head assembly, means for controlling flow of spray solution to said spray head assembly and said boom position adjusting means, and means for assembling all of said control means in a unitary assembly within convenient reach of such operator, said means for assembling all of said control means within convenient reach of an operator on such vehicle, including a housing with said control means therein, and a plate affixed to a wall of said housing and extending beyond the bottom thereof, said plate being sufficiently thin to enable insertion thereof into the window slot of a door on such vehicle, to permit removable installation of said housing and included control means on the window sill of such door within convenient reach of an operator occupying a seat adjacent such door.
