A tarpaulin dolly has a first base plate with a plurality of wheel assemblies attached to its underside surface. A flexible tarpaulin sheet is secured between an upper facing surface of the first base plate and a second base plate disposed above the sheet so as to provide a captured portion and a larger excess portion of the sheet. A method of moving material, article, or debris using the tarpaulin dolly which is particularly useful in removing used roofing shingles from a pitched roof, includes the steps of providing the tarpaulin dolly to a location, placing material, article, or debris upon the excess portion of the tarpaulin sheet or the second base plate, and moving the tarpaulin dolly.

The paint caddy as claimed in claim 6, said means for maneuvering comprises a manually grippable handle extending vertically from the rearward end of the frame to enable the user to push the frame horizontally as well as to apply upward and downward vertical forces to the frame, and said first and second pairs of non-swivelable casters, wherein the downward force on the handle operates with the rearward pair of non-swivelable casters to simultaneously pivot the rearward end portion of the frame downwardly and the respective rollers thereat into engagement with the ground and lift the forward end portion of the frame upwardly and the respective rollers and casters proximate thereto from the ground to enable movement of the forward end of the frame over an obstacle in the path of the frame, and conversely, the upward force on the handle operates with the forward pair of non-swivelable casters to simultaneously pivot the forward end of the frame downwardly and the rollers proximate thereat into engagement with he ground and lift the rearward end portion of the frame upwardly and over an obstacle in the path of the frame. 8. A multipurpose paint caddy, the paint caddy comprising: a support frame, the support frame having a top, a bottom, a pair of laterally spaced opposite sides, a front, and a rear; means for positioning a paint bucket on the top of said frame; a grippable handle extending from the frame for pushing and manipulating the frame, the handle enabling the user to apply forces used to lift up and/or push down one or the other end of said frame; a pair of vertically spaced generally concentric ring frames, one and the other of said frames being proximate to and spaced vertically from the top of said frame and dimensioned to encircle the bottom and medial portions of the paint bucket; a first and second pair of wheels extending downwardly from the bottom of said frame and the wheels of each pair being proximate to a respective of said opposite sides, said first and second pairs of wheels being disposed between the forward and rearward ends of the frame and adapted to be normally disposed in engagement with the ground to enable movement of the frame along the ground; and a third and fourth pair of wheels extending downwardly from the bottom of said frame and the wheels of each pair being proximate to a respective of said opposite sides, said third pair of wheels being disposed between the forward end and said first pair of wheels, and said fourth pair of wheels being disposed between said rearward end and said second pair of wheels, said third and fourth pair being spaced from the frame by an amount less than the said first and second pairs of wheels, wherein a downward force on the handle rotates the frame relative to the second pair of wheels and drives the rearward end and said fourth pair of wheels downwardly into engagement with the ground and lifts the forward end and the first pair of wheels from engagement with the ground, and oppositely, an upward force on the handle rotates the frame relative to the first pair of wheels and drives the forward end and said third pair of wheels downwardly and into engagement with the ground. 9. The paint caddy as claimed in claim 8, wherein the wheels of said first and second pairs of wheels are substantially of a like first diameter, and the wheels of said third and fourth pairs of wheels are substantially of a like second diameter, the first diameter being greater than said second diameter. 10. The paint caddy as claimed in claim 8, wherein the wheels of said first and second pairs of wheels are mounted non-swiveling rotation movement about respective axes extending laterally between the opposite sides of the frame, and the
