Abstract
A corner finishing tool for applying mastic material along a wall joint comprising an angular retainer plate having a pair of integral sides resiliently joined at a corner, a pair of L-shaped rigid frame members secured thereto, one side and frame member being resiliently movable relative to the other side and frame member while together defining a cavity reservoir for mastic material, and a wheel having substantially conical side surfaces that converge to a center rim. The corner finishing tool also provides means for setting the L-shaped rigid frame members to a preset position under an adjustable resilient biasing force.
Claims9
A corner finishing tool for applying mastic material along a wall joint comprising container means defining a cavity that is open in two convergent and substantially perpendicular planes and having surfaces in each of said planes that converge peripherally of said cavity for doctoring mastic material that flows thereunder;
- and a wheel having substantially conical side surfaces that converge to a center rim, said wheel being rotatably mounted from said container means to contact the walls of a wall joint with the conical side surfaces and position the cavity relative thereto.
A corner finishing tool for applying mastic material along a wall joint comprising:
- container means defining a cavity that is open in two convergent and substantially perpendicular planes and having surfaces in each of said planes that converge peripherally of said cavity for doctoring mastic material that flows thereunder, said container means comprising an angular retainer plate having a pair of integral sides resiliently joined at a corner;
- a pair of L-shaped rigid frame members secured to said pair of integral sides, respectively, one side and frame member being resiliently movable relative to the other side and frame member while together defining a cavity reservoir for mastic material;
- and a pair of convergent doctor blades supported in one leg of each frame member and coming together proximate the corner of said retainer plate.
