Abstract: A water jet cleaner for the underside of a vehicle. A plurality of jets are directed upwardly from a spray head which is mounted on a longitudinal member positioned closely to the ground on which the vehicle is resting. A handle is attached to the longitudinal member and wheels are mounted to the frame and the longitudinal member to allow manual reciprocal movement of the cleaner beneath the vehicle by an operator. The jets are angularly adjustable such that the cleaner may also be used to clean the surface itself such as a driveway.

Abstract: A water spray apparatus for dual function use in washing motor vehicle undercarriages or in cleaning ground surfaces. The apparatus has a hollow cross tube axially supported by a pair of wheels and pivotally connected to a union. The cross tube has a row of commonly facing orifices for generating a row of commonly directed water streams. Directional reversal of the water streams is accomplished by pivoting rotation of the cross tube.

Abstract: The device serves for eliminating deposits (52) in ventilation ducts (14) in the stationary or non-stationary operating mode. The cleaning medium is a fluid sprayed out under high pressure from a spray head (3). The spray head (3) is carried by a supply pipe (2), through which lead the drive shaft coming from a motor (1) and a fluid channel. In the non-stationary operating mode, the device is integrated into a slide (15) which is pulled through the ventilation duct (14). The slide (15) is introduced into the ventilation duct (14) through an inspection port sealable by means of an inspection cover. Ventilation ducts (14) extending horizontally, vertically and obliquely can be treated. In the stationary operating mode for cleaning an inlet or outlet, a bend or a branch and, for example, also a vapour extractor, the device is held without a slide (15) in a supporting cover which is inserted into the inspection port.

Abstract: A system for thoroughly spraying buildings with a pesticide. A truck carries a tank of liquid pesticide, a hose on a reel and a pump for pumping pesticide into the hose. A cart including a tube having a first end for connection to the hose and a second end carrying one or more spray heads is placed at the far end of a building with the hose extending the length of the building and out a door to the truck. The tube is mounted on at least two wheels, with a sled member supporting the end of the tube adjacent to the hose connection. The spray heads produce a pattern in approximately a vertical plane perpendicular to the length of the tube and hose. As the hose is reeled up, the cart is pulled across the floor of the building, with the fan-like spray pattern fully treating the building interior.

The inlet side of the pump is connected to a suction hose that is either placed into a nearby body of water or connected to a municipal water source. The outlet side of the water pump is connected to one end of a pressure hose. The pressure hose is normally coiled on a storage take-up reel mounted to the frame, and has a nozzle at one end. Additional hose storage frame may be included on the frame for extending the pressure hose if necessary.

Abstract: An improved tractor for earth grading and soil compaction having a hydraulically operated bucket mounted on the front and including a water tank and water spray nozzle. The water spray nozzle is positioned on the bucket so that it can add water to soil as it is moved by the bucket and also can be raised and aimed by the tractor operator. This permits the tractor operator to use the water spray to wet down a load of soil in a truck.

Abstract: An irrigation line gate is adapted to be connected between an upstream irrigation line and a downstream irrigation line of a mobile irrigation system to allow lateral movement of the irrigation line past a stationary obstacle in a direction perpendicular to the length of the line. The irrigation line gate comprises longitudinally-spaced upstream and downstream manifolds connected between upstream and downstream movable irrigation lines. Laterally-spaced retractable gate pipes extending between the manifolds are sequentially opened to clear an obstacle as the irrigation line passes the obstacle. Each gate pipe is supported adjacent one of the manifolds by a longitudinally-spaced pair of pipe support collars. Each pair of support collars receives one of the gate pipes therethrough for slidable movement between open and closed positions.

Abstract: An undercarriage sprayer is provided for automobiles and the like. The sprayer has a T-shaped frame with a castor wheel at the base of the T and two steerable wheels at the ends of the cross bar. A handle connected to the frame at the intersection of the T is used to manipulate the sprayer and to steer the wheels through the use of a rotating hand grip. Spray nozzles are spaced along the base arm of the T-frame and may be arranged to pivot from side to side under the control of an operator. In other embodiments, the nozzles may be rotating spray heads.

Abstract: A stripper applicator employs a positive displacement gear pump to spray high viscosity stripper materials. The gear pump is driven at a reduced speed by an electric motor. A pressure relief valve is inserted in the outlet port of the gear pump to adjust the delivery pressure of the liquid. A large diameter suction line draws the liquid from a container to the pump without priming, and a dump line returns overflow liquid from the relief valve to the container. The stripper applicator is capable of delivering 1.5 gallons per minute of liquid at relatively low pressure to the delivery hose, which terminates in a spray gun. The electric motor and gear pump are mounted to a portable and light weight chassis.
