Abstract
A roller cover and associated pair of cams attachable to opposite ends of the roller cover. Each of the cams has an outer diameter extending radially outwardly beyond an outer diameter of the roller cover a predetermined distance for maintaining the outer diameter of the roller cover a corresponding distance from the surface being coated during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface.

In combination, a plurality of pairs of roller cover cams for use in maintaining an outer diameter of a roller cover a predetermined distance from a surface to which a spreadable coating is to be applied by the roller cover during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface, each of the roller cover cams having an axially outer flange portion and an axially inner roller attachment portion for attaching the roller cover cams to opposite ends of the roller cover, and the axially outer flange portion of the roller cover cams having an outer diameter greater than the outer diameter of the roller cover a predetermined amount to act as a thickness gauge for the coating being applied to the surface during rotational movement of the roller cover over the surface, and the axially inner roller attachment portion having a radially outer surface for engaging a radially inner surface of the roller cover to preclude radial shifting of the roller cover cams relative to the roller cover, and wherein the plurality of pairs of the roller cover cams have different outer diameters all greater than the outer diameter of the outer covering of the roller cover and are interchangeable to provide different thickness gauges for the coating to be applied to the surface during rotational movement of the roller cover over the surface, thereby enabling a user to select from the plurality of pairs of roller cover cams a given pair to provide a corresponding thickness of the coating to be applied.
Roller cover cams for use in maintaining an outer diameter of a roller cover a predetermined distance from a surface to which a spreadable coating is to be applied by the roller cover during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface, each of the roller cover cams having an axially outer flange portion and an axially inner roller attachment portion for attaching the roller cover cams to opposite ends of the roller cover, and the axially outer flange portion of the roller cover cams having an outer diameter greater than the outer diameter of the roller cover a predetermined amount to act as a thickness gauge for the coating being applied to the surface during rotational movement of the roller cover over the surface, and the axially inner roller attachment portion having a radially outer surface for engaging a radially inner surface of the roller cover to preclude radial shifting of the roller cover cams relative to the roller cover, wherein the outer diameter of the axially outer flange portion has an outer peripheral edge containing a plurality of circumferentially spaced notches to reduce the amount of surface contact of the roller cover cams with the surface being coated during rotational movement of the roller cover over the surface to which the coating is being applied, and wherein the circumferentially spaced notches of the plurality of circumferentially spaced notches have a radius of between approximately 0.10 inch and approximately 0.15 inch.
Roller cover cams for use in maintaining an outer diameter of a roller cover a predetermined distance from a surface to which a spreadable coating is to be applied by the roller cover during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface, each of the roller cover cams having an axially outer flange portion and an axially inner roller attachment portion for attaching the roller cover cams to opposite ends of the roller cover, and the axially outer flange portion of the roller cover cams having an outer diameter greater than the outer diameter of the roller cover a predetermined amount to act as a thickness gauge for the coating being applied to the surface during rotational movement of the roller cover over the surface, and the axially inner roller attachment portion having a radially outer surface for engaging a radially inner surface of the roller cover to preclude radial shifting of the roller cover cams relative to the roller cover, wherein the outer diameter of the axially outer flange portion has an outer peripheral edge containing a plurality of circumferentially spaced notches to reduce the amount of surface contact of the roller cover cams with the surface being coated during rotational movement of the roller cover over the surface to which the coating is being applied, and wherein there are 10 to 20 circumferentially spaced notches in the outer peripheral edge of the roller cover cams.
