Abstract
Line painting equipment mounted on a small tractor with an air compressor mounted on the front of the tractor and a paint containing tank mounted on its rear portion. A further elongated pressurized paint container is mounted on one side of the tractor and inclined downwardly towards the front of same. A boom is clamped to the tractor forward of the pressurized paint container which is also normally inclined downwardly towards the front of the tractor. The boom is so secured to the tractor that it can be selectively rotated on its longitudinal axis, moved outwardly on a substantially vertical axis and moved vertically about a substantially horizontal axis. A paint spray gun is removably mounted on the front of the boom as is an adjustable boom support wheel which governs the height of the paint spray gun over the underlying surface. An adjustable guide to indicate to the operator where the paint is sprayed is mounted from the steering linkage of the tractor. One line from the air compressor is utilized to pressurize the elongated paint container and the other line leads to the spray paint gun. Paint is fed from the bottom of the elongated pressurized paint container to the paint gun. A further line connects the compressor air to the elongated container for bubbling air through same as a means of agitating the paint therein. A still further line with a valve therein provides paint from the paint tank on the back of the tractor to the elongated paint container. An air line to actuate the paint gun is a foot-controlled air valve. Exhaust from the internal combustion engine of the tractor is carried through an exhaust pipe to blow exhaust towards the surface area immediately ahead of that which is to be painted for clearing debris and the like therefrom. The paint gun is removable from its support on the boom and can be held by hand or otherwise stored in a paint solvent containing cap on the tractor. A limit bar extends from the tractor for limiting the downward movement of the boom whereby the paint spray gun cannot accidently be dislodged to fall on the underlying surface during the painting operation.
