Abstract

A spraying apparatus which is particularly suitable for spraying a marking stripe on pavement, grass, or other surfaces is provided with adjustable axles so that the distance of the spray can from the surface can be changed to vary the width of the stripe and with a wind screen which remains in the same relative position with respect to the surface as the axles are adjusted to protect the spray pattern from wind. The apparatus includes a somewhat box-like frame, and the sides of the frame are provided with generally vertically extending front and rear rows of openings for the front and rear axles. The frame includes holding means for holding an aerosol spray can filled with marking material, and the holding means are constructed and arranged so that the marking material is sprayed substantially below the front of the frame to permit marking stripes to be sprayed right up to an obstacle in front of the spraying apparatus. The wind screen extends around the outside of the frame, and each side of the wind screen is provided with a front and a rear opening through which the front and rear axles extend. The openings in the wind screen are positioned relative to the bottom edge of the wind screen so that the bottom edge will be positioned just above the surface to be sprayed. As the distance of the frame from the surface is varied by inserting the axles through various openings in the frame, the position of the wind screen relative to the surface remains constant since only one opening for each axle is provided through each side of the wind screen.

Claims

1. A spraying apparatus comprising a frame having a pair of spaced-apart side walls, each of the side walls of the frame being provided with front and rear generally vertically extending rows of spaced-apart openings, a front axle extending through one of the front openings in each of the side walls of the frame and a rear axle extending through one of the rear openings in each of the side walls of the frame, the front and rear axles being selectively insertable through each of the openings in the front and rear rows, respectively, whereby the distance of the frame from the surface to be sprayed can be varied, front and rear wheels mounted on the front and rear axles, respectively, and a wind screen having front, rear, and opposite side walls, each of the side walls of the wind screen being provided with a front and a rear opening through which the front and rear axles extend, the openings in the wind screen being positioned so that the lower edge of the wind screen is positioned slightly above the bottom of the wheels.

2. The apparatus of claim 1 including holding means on the frame for supporting a valve-equipped spray can in position to dispense the contents of the can on the surface to be sprayed, the holding means being constructed and arranged to hold the can so that the contents thereof are sprayed on the surface adjacent the lower edge of the front wall of the wind screen.

3. A spraying apparatus comprising a frame having front, rear, and opposite side Walls, each of the side walls of the frame being provided with front and rear generally vertically extending rows of spaced-apart openings, a front axle extending through one of the front openings in each of the side walls of the frame and a rear axle extending through one of the rear openings in each of the side walls of the frame, the front and rear axles being selectively insertable through each of the openings in the front and rear rows, respectively, whereby the distance of the frame from the surface to be sprayed can be varied, front and rear wheels mounted on the front and rear axles, respectively, and a wind screen having front, rear, and opposite side walls positioned outwardly of the respective walls of the frame, each of the side walls of the wind screen being provided with a front and a rear opening through which the front and rear axles extend, the openings in the wind screen being positioned so that the lower edge of the wind screen is positioned slightly above the bottom of the wheels.

4. The apparatus of claim 3 including holding means on the frame for supporting a valve-equipped spray can in position to dispense the contents of the can on the surface to be sprayed, the holding means being constructed and arranged to hold the can so that the contents thereof are sprayed on the surface adjacent the lower edge of the front wall of the wind screen.
