Abstract

This invention relates to lawn spreader markers generally, and more specifically to an intermittent manually controlled marking apparatus which delineates the area covered by the spreader hopper opening and which utilizes foam as the marking material.

Claims

1. A marking device for a lawn spreader comprising:

a bracket secured to the spreader body;

an aerosol can filled with marking material pivotably supported on said bracket via a retaining member; and

at least one cam means mounted on one wheel of said spreader, and adapted to engage the aerosol can to dispense its contents beneath the lawn spreader.

2. A marking device as in claim 1 wherein the retaining member comprises:

a cylindrical member configured to receive and support the aerosol can; and

a hinge element securing said cylindrical member to said bracket.

3. A marking device as in claim 2 wherein the retaining member further comprises:

a horizontally disposed abutment member bearing a nozzle on one end of said cylindrical member;

a flexible abutment member on the other end of said cylindrical member; and

clamping means disposed on said cylindrical member for releasably securing said aerosol can in said retaining member.

4. A marking device as in claim 3 wherein:

the flexible abutment member resiliently biases the aerosol can against the horizontally disposed abutment member.

5. A marking device as in claim 3 wherein:

said nozzle is configured to receive the outlet of the aerosol can and position the depressable actuator of the can in the path of travel of the cam.

6. A marking device as in claim 5 wherein:

a spring element normally biases the retaining member to a position wherein the nozzle is disposed perpendicular to the surface over which the lawn spreader travels, and the depressable actuator is positioned in the path of travel of the cam.

7. A marking device as in claim 6, further comprising:

manually actuated means to pivot the retaining member to a position wherein the depressable actuator of the can is rotated out of the path of travel of the wheel mounted cam.

8. A marking device as in claim 3 wherein:

the nozzle is positioned in the same vertical plane as one end of the lawn spreader outlet opening.

9. A marking device as in claim 1 wherein:

the marking material is shaving cream.

10. A marking device for a lawn spreader comprising:

an aerosol can of foam material pivotally disposed on the body of the lawn spreader; and

one or more cam elements mounted on a wheel of the lawn spreader and positioned to intermittently engage the aerosol can actuator as the wheel rotates to dispense the contents of the can as the wheel traverses a surface over which the lawn spreader moves.
