Filed:

Sep 9, 1974

Appl. No.:

5/504253

Inventors:

Eugene R. Johnson - Burlingame CA
Morris F. Mower - Santa Clara CA

Assignee:

Bliss & Laughlin Industries, Inc. - Oak Brook IL

International Classification:

B28B 708
B05C 1710

US Classification:

425458

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.

Assignee:

Bliss & Laughlin Ind., Inc. - Oak Brook IL

International Classification:

B05C 1710

US Classification:

425458

Abstract:

A corner tool for applying mastic material to an external corner formed by two walls which come together at approximately 90. degree. , said tool comprising a retainer for mastic material that defines a cavity open in two convergent and substantially perpendicular planes, including a pair of slotted screed plates that extend substantially perpendicular to each other and transverse relative to the external corner, and means for positioning the mastic retainer relative to the external corner to maintain the slotted plates in contact with the two walls forming the corner while positioning the cavity in open-spaced relationship to the walls.

Bliss & Laughlin Industries, Inc. - Oak Brook IL

International Classification:

B32B 3100
B44C 700

US Classification:

156526

Abstract:

A tape applicator and mastic dispenser for dry wall taping comprising a holder for a replaceable cartridge, means for forcing mastic material from said cartridge through a discharge outlet onto a tape, tape advancing means for feeding a tape from a supply roll beneath the discharge outlet, a roll for applying a mastic coated segment of tape onto a wall joint and means connecting the roll to the tape advancing means for positioning the roll in retracted or tape supporting position by actuation of the tape advancing means, whereby the pressure roll is retracted as tape is advanced beneath the discharge outlet and selectively positionable in front of the dispenser for supporting and applying mastic coated tape to a wall joint.
