Abstract

A spraying apparatus which is particularly suitable for painting stripes on pavement, grass or the like. The apparatus includes a wheeled frame and an upwardly extending handle for pushing the frame over the surface that is to be marked. The frame includes a base plate which is provided with an opening to receive the valve end of an inverted aerosol spray can, and side plates extend from the base plate to maintain the can in a substantially upright position. The valve of the can is actuated by a slide plate which is slidably secured to the base plate, and sliding movement of the slide plate is effected by a bell crank which is rotatably mounted on the frame. A cable extends along the handle between the bell crank and a trigger mounted on the upper end of the handle, and actuation of the trigger actuates the can valve to spray the marking contents of the can generally downwardly toward the surface.

Claims

1. A spraying apparatus comprising a frame having a base plate and a pair of spaced-apart side plates extending generally upwardly from the base plate, the base plate having a pair of openings, each opening adapted to receive the valve end of an aerosol spray can, the spray cans adapted to be positioned between the side plates, wheels rotatably mounted on the frame for permitting the apparatus to be rolled over a surface to be sprayed, a handle secured to the frame and extending generally upwardly therefrom for moving the apparatus along the surface, a valve-actuating plate slidably secured to the base plate for sliding movement in a direction generally parallel to the base plate, the valve-actuating plate being positioned below the openings in the base plate whereby the valve-actuating plate is engageable with the can valves, means for slidably moving the valve-actuating plate into engagement with the can valves whereby the contents of the cans may be sprayed downwardly onto the surface to be sprayed, and means for varying the included angle between the side plates whereby the sprays from the aerosol cans can be made more or less convergent.

2. The apparatus of claim 1 including spring means secured to the base plate between the openings for biasing the upper ends of the aerosol cans away from each other and toward the side plates.

3. The apparatus of claim 1 including a masking plate secured to the frame and extending below the base plate, the masking plate having an opening therethrough for controlling the pattern of the marking material deposited on the surface to be marked.

4. A spraying apparatus comprising a frame, wheels rotatably mounted on the frame for permitting the apparatus to be rolled over a surface to be sprayed, holding means on the frame for supporting a valve-equipped spray can in position to dispense the contents of the can onto the surface to be sprayed, a handle secured to the frame for moving the apparatus along the surface, and actuating means movably mounted on the frame adapted to engage the valve of the container for releasing the material, the actuating means including a plate slidably secured to the frame and movable between non-actuating and actuating positions, spring means secured to the frame and to the plate for biasing the plate to the non-actuating position, crank means mounted on the frame for rotation in a plane generally perpendicular to the direction of sliding movement of the plate, the crank means being engageable with the plate whereby rotation of the crank means imparts sliding movement to the plate, and means for rotating the crank means.

5. The apparatus of claim 4 including a masking plate secured to the frame and extending below the holding means, the masking plate having an opening therethrough for controlling the pattern of the marking material deposited on the surface to be marked.

6. The apparatus of claim 4 in which the means for slidably moving the valve-actuating plate includes a crank mounted on the frame for rotation in a plane generally perpendicular to the direction of sliding movement of the valve-actuating plate and being engageable with the valve-actuating plate, and a cable secured to the crank and extending along the handle whereby movement of the cable may rotate the crank and slide the valve-actuating plate into engagement with the can valve.

7. The apparatus of claim 6 including trigger means on the handle, the cable being secured to the trigger means whereby the cable can be moved by the trigger means to rotate the crank.

8. The apparatus of claim 4 including locking means engageable with the trigger means for releasably holding the trigger in position to actuate the can valve.

9. The apparatus of claim 4 including spring means secured to the frame and to the valve-actuating plate for biasing the plate to a non-actuating position.

10. The apparatus of claim 4 in which the frame includes a base plate provided with an opening therethrough for receiving one end of the container, the actuating means including an actuating bar secured to the plate and extending adjacent the opening and spaced therebelow and being movable in a plane extending generally parallel to the base plate and spaced therefrom.

11. A spraying apparatus comprising a frame having a base plate and a pair of spaced-apart side plates extending generally upwardly from the base plate, the base plate having an opening therethrough adapted to receive the valve end of an aerosol spray can, wheels rotatably mounted on the frame for permitting the apparatus to be rolled over a surface to be sprayed, a handle secured to the frame and extending generally upwardly therefrom for moving the apparatus along the surface, a valve-actuating plate slidably secured to the base plate for sliding movement in a direction generally parallel to the base plate, the valve-actuating plate being positioned below the opening in the base plate and including an actuating portion spaced from the base plate and engageable with the can valve, and means for slidably moving the valve-actuating plate to bring the actuating portion thereof into engagement with the can valve whereby the contents of the can may be sprayed downwardly onto the surface to be sprayed.

12. The apparatus of claim 11 in which the valve-actuating plate includes an elongated slide portion slidably secured to the base plate, the actuating portion of the valve-actuating plate extending generally transversely to the slide portion.

13. The apparatus of claim 11 in which the valve-actuating plate includes an elongated slide portion slidably secured to the base plate, the actuating portion of the valve-actuating plate extending generally transversely to the slide portion, the slide portion being provided with a longitudinally extending slot, a bolt extending through the slot and secured to the base plate for holding the valve-actuating plate adjacent the base plate and for guiding the sliding movement of the valve-actuating plate, means for slidably moving the valve-actuating plate including a crank mounted on the frame for rotation in a plane generally perpendicular to the direction of sliding movement of the valve-actuating plate, a portion of the crank extending through the slot in the valve-actuating plate and engageable with the valve-actuating plate at the end of the slot.

14. A spraying apparatus comprising a frame including a base plate having upper and lower surfaces and having a pair of spaced-apart openings, each opening adapted to receive the valve end of an aerosol spray can, wheels rotatably mounted on the frame for permitting the apparatus to be rolled over the surface to be sprayed, a handle secured to the frame and extending generally upwardly therefrom for moving the apparatus along said surface, a slide plate having a slide portion slidably secured to the lower surface of the base plate for sliding movement in a direction generally parallel to the base plate and along a line extending generally perpendicularly to a line extending between the centers of the openings in the base plate, the slide plate including an actuating bar which is spaced from the lower surface of the base plate and which extends generally parallel to a line extending between the centers of the base plate openings, the actuating bar extending to adjacent the center of each opening in the base plate whereby the actuating bar is engageable with the valve of each spray can when the slide plate is moved, and means for slidably moving the slide plate to bring the actuating bar into engagement with the valves of each spray can whereby the contents of each can may be sprayed downwardly onto the surface to be sprayed.

15. The apparatus of claim 14 in which the slide portion of the slide plate extends between the openings in the base plate and the actuating bar extends transversely from the slide plate in both directions to provide the slide plate with a generally T-shape.
