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.
