Abstract: A recess filling mastic applicator having a novel tool-steering means and a straight torsional spring adjustable as to its effective length for causing the tool body to have a four point contact with the surface over which the tool body travels. The interior of the tool body receives mastic and a pressure plate is pivotally mounted in the body and a handle is pivotally connected to the plate so that the operator can press on the handle for not only holding the body against the flat surface but for also depressing the plate for forcing mastic from the tool for filling the recesses in the surface as the tool is moved thereover. The tool body steering means connects the handle to the pressure plate so that a twisting force applied to the handle will urge the leading end of the tool body to the right or to the left as desired by the operator and thus alter the direction of movement of the tool body.Cross-Reference to Related U.S. Pat.

Abstract: A self-contained dry wall taper has a hollow elongated body for holding mastic and supports a roll of tape with tape feeding means to deliver the tape to tape applying wheels that in turn apply it to cover a joint between two wall board sections.A piston is slidably mounted in the hollow body and is automatically moved by a mechanism actuated by the rotating wheels, as they are moved over the wall board surface, to force a layer of mastic onto the tape just prior to it being applied to the surface. Novel tape feeding and tape cutting means are actuated by a single sleeve which is moved forwardly on the hollow body to initially feed the tape into engagement with the tape applying wheels and is moved rearwardly to actuate the tape-cutting mechanism for cutting the tape.
