Abstract

A pavement line striper is provided which has a pair of spaced apart front wheels and a pivotable rear steering wheel. Paint spray guns may be mounted closely adjacent to one or both of the front wheels. One of the front wheels is laterally movable to allow for the painting of parallel stripes of selectively variable spacing. Two guns may be mounted on one side for vertical and horizontal spraying of a curb in one pass or for closely spaced parallel lines. The guns remain closely adjacent the wheels to minimize uneven thickness of the lines when spraying on uneven terrain. The rear wheel is lockable against pivoting movement and indicia markings are provided to permit selection of a radius for curved lines.

Claims

1. A device for spraying lines on a pavement comprising:

a frame member;

a paint reservoir mounted on said frame for holding an supply of paint;

means mounted on said frame for pressurizing said paint;

a plurality of wheels mounted on said frame to permit said frame to be rolled on said pavement;

means for mounting two of said wheels on a common axis;

a pluraity of spray guns connected by conduit means to said pressurized paint;

means for removably mounting said spray guns closely adjacent at least one of said wheels and selectively positionable along the vertical plane of said common wheel axis;

means for selectively and independently manually activating said spray guns for applying paint to said pavement;

at least one of said spray guns being removably mounted to the mounting means of said wheels;

means for laterally extending one of said wheels on said common axis, and said one of said spray guns, relative to said frame;

whereby, said one of said spray guns can be moved laterally relative to said frame without changing its proximity to its associated wheel.

2. The device of claim 1 wherein said wheels comprise two front spaced apart fixed wheels on said common axis and a single pivotable steerable rear wheel, said spray gun mounting means being adjacent at least one of said front wheels.

3. The device of claim 2 wherein a spray gun is mounted outboard of each of said two front wheels.

4. The device of claim 2 wherein a first spray gun is mounted inboard of one of said front wheels and a second spray gun is mounted outboard of said front wheel.

5. The device of claim 2 wherein said rear wheel is lockable against pivoting.

6. The device of claim 2 wherein a pointer and dial are provided at said rear wheel to permit the selection of a desired turning radius by appropriate pivoting of said rear wheel.

7. The device of claim 1 wherein two spray guns are mounted outboard of said one of said wheels relative to said frame, each gun being mounted along the vertical plane of said common wheel axis.

8. The device of claim 7 wherein one of said spray guns has a nozzle directing spray downwardly and said second spray gun has a nozzle directing spray horizontally outwardly whereby a top and side surface of a curb can be sprayed simultaneously.

9. In a device for spraying lines on a pavement which includes a wheeled frame having means for mounting a spaced apart pair of front wheels on a common axis, a pivotable rear steering wheel and carrying a reservoir of paint, means for pressurizing the paint, and at least two spray guns for applying the paint on the pavement, the improvement comprising:

mounting means for adjustably securing each of said spray guns adjacent at least one of said front wheels and selectively positionable along the vertical plane of said common axis; and

means for laterally adjusting the position of said one of said front wheels relative to said frame;

at least one of said spray gun mounting means being secured to the mounting means for said wheel to move laterally with said wheel;

whereby, said one of said spray guns may be moved laterally relative to said frame and said other spray gun while remaining adjacent said laterally movable front wheel.

10. The device of claim 9 wherein two spray guns are mounted outboard of said laterally movable wheel relative to said frame.

11. The device of claim 9 wherein one of said spray guns is mounted outboard of each of said two front wheels.

12. The device of claim 9 wherein a first spray gun is mounted inboard of said laterally movable wheel and a second spray gun is mounted overboard of said laterally movable wheel.

13. A device for spraying lines on a pavement comprising:

a frame member;

a paint reservoir mounted on said frame for holding a supply of paint;

means mounted on said frame for pressurizing said paint;

two spaced apart and pivotally fixed front wheels secured to said frame on a common axis;

one of said front wheels mounted on an axle which is selectively movable laterally along said common axis relative to said frame;

a pivotable rear wheel secured to said frame;

a plurality of spray guns connected by conduit means to said pressurized paint;

means for removably mounting said spray guns closely adjacent said front wheels and selectively positionable along the vertical plane of said common axis;

at least one of said spray guns being mounted on said axle adjacent said laterally movable wheel; and

means for selectively and independently manually activating said spray guns for applying paint to said pavement;

whereby said spray gun mounted adjacent said laterally movable wheel may also be moved laterally with said wheel.

14. The device of claim 13 wherein said spray guns can be removed from said device for hand held spraying.
