Abstract
A liquid spraying apparatus includes a chassis having a front, a rear, opposite sides and a handle generally at the rear of the chassis. Wheels are rotatably mounted on the chassis for moving the spraying apparatus in a path over a subjacent surface. A tank is mounted on the chassis for holding liquid to be sprayed. An elongated spray boom is mounted at least at one side of the chassis. The boom has an inner end pivotally mounted to the chassis for movement of an outer end in a generally horizontal plane between an outboard position projecting outwardly of the chassis and an inboard position generally alongside the chassis. At least one spray nozzle is provided on the boom. Conduits are provided for feeding liquid from the tank to the nozzle. Positioning detents are provided for holding the boom in at least one intermediate position between the outboard and inboard positions to vary the width of the spray pattern as the apparatus is moved in the path over the subjacent surface.
