Abstract: A multi-purpose, movable apparatus (henceforth dolly-truck) for conveying objects, such as, for example, a five-gallon cylindrical industrial bucket is described. The dolly-truck includes a one-piece, molded plastic base having caster wheels and truck wheels. The caster wheels are mounted on a lower surface of the base and provide short distance rolling movement capability in the upright position. Connected to the base are two truck support arms which support an axle with two truck wheels. The truck wheels provide a hand truck capability for negotiating stairs, bypassing obstacles and an omnidirectional capability in conveyance of objects. Centered on the base is a retaining wall for receiving and holding objects. Connected to, and integrated into the retaining wall is an adjustable handle for conveying the dolly-truck by hand. The handle can be used to move the dolly-truck on the caster wheels as a conventional dolly, or alternatively on the truck wheels as a conventional hand truck.

Abstract: A generally polygonal block-like enclosure of rigid material including a top and bottom wall, a pair of a concave inward front walls which define an inner corner adapted to fit on an outside corner, and a back wall spaced from the front walls by a pair of spaced side wall. The back wall includes a centrally disposed spherical cavity sized for receiving a bail socket connector which is preferably retained therein by a spring clip or equivalent retaining means and each front wall includes a vertically oriented channel which extend between the top and bottom walls. The enclosure also includes a manifold which connects the spherical cavity in the back wall to each of the channels in the front wall.

Abstract: Apparatus for applying tape and mastic to joints between prefabricated wall sections such as gypsum board comprising a tubular housing which holds a supply of mastic, a main drive roller mounted at the forward end of the housing which rotates by friction as it is moved along a wall and tape drive roller means operated by the main drive roller and which feeds the tape forwardly.
