Abstract
Abstract A roadside spray apparatus primarily adapted for the precision application of chemical herbicides is mounted by means of a frame support on the front bumper of a vehicle and is monitored by the driver of the vehicle using one hand to operate electrical switches connected to solenoid valves controlling the spray through nozzles mounted on a spray boom, which boom can be adjusted laterally and can be pivoted from one side of the vehicle to the other, with the nozzles attached to coil springs on the spray boom, and with an adjustable mirror and adjustable guides located on the spray apparatus in view of the driver of the vehicle.

Claim 6
Dependent Claim
41 words
A spray apparatus in accordance with claim 2, wherein: the nozzles located from the lateral center of said vehicle to the outside edge of the inside boom are positioned at a height not substantially less than eighteen inches above ground level.
Claim 7
Dependent Claim
40 words
A spray apparatus in accordance with claim 2, wherein: the flexible coil springs with a plurality of nozzles located to the outside of said coil springs are located at heights ranging between ten inches and forty-eight inches above ground level.
Claim 8
Dependent Claim
33 words
A spray apparatus in accordance with claim 2, wherein: the direction of spray of said nozzles is adjustable with respect to distances desired to be sprayed away from the side of said vehicle.
Claim 9
Dependent Claim
64 words
A spray apparatus of claim 1, wherein: the lower horizontal channel member of the frame is attached to bar means detachedly connected by locking pins to bumper mounts fixedly connected to the front bumper of the vehicle, said pins being located on the back side of the lower horizontal channel member and which can be pulled to detach the supporting frame from the vehicle.
Claim 10
Dependent Claim
41 words
A spray apparatus of claim 1, characterized by: two additional horizontal members located between the lower channel member and the upper bar and being upper and lower horizontal bars for a plurality of electric solenoid valves located within the supporting framework.
Claim 11
Dependent Claim
88 words
A spray apparatus in accordance with claim 9 for the application of a single herbicide comprising: a plurality of electric solenoid valves on the upper horizontal solenoid bar and which are electrically controlled by a plurality of switches on a control panel located inside the vehicle, which can be activated individually and in concert, with spray fluid being supplied by means of a pump attached to and operated by the engine of said vehicle with hoses connecting each solenoid valve to a nozzle located along said boom members.
Claim 12
Dependent Claim
25 words
A spray apparatus in accordance with claim 10, which: incorporates a pressure gauge which can be easily read above the vehicle hood by the operator.
