A tool for use in connection with a wall covering material source having a nozzle to dispense wall material to be applied to a wall. The has a plate having a front surface, and a back surface which is adapted to slide along the wall surface. The back surface defines an opening, and the plate defines a passageway passing through the plate and coupled to the back surface opening. A tube connected to the front surface of the plate and coupled to the passageway of the plate is adapted to receive the nozzle of the wall material source. The plate passageway directs the wall material dispensed from the source nozzle to the back surface opening to be delivered for application to the wall surface.

A switching power supply includes: a transformer including primary and secondary windings; a switching circuit including first and second switching elements, first and second rectifying elements, first and second capacitive elements and a first inductor; and a rectifying/smoothing circuit. A first bridge circuit is configured by the first and second switching elements located in a diagonal arrangement and the first and second capacitive elements also located in a diagonal arrangement. The first and second rectifying elements are connected in parallel to the first and second switching elements, respectively. One of the first and second rectifying elements is in forward direction and other is in inverse direction. The first inductor is disposed on a connection line between the pair of input terminals and the first bridge circuit. The primary winding is connected to the first bridge circuit to form a H-bridge configuration. The secondary winding is disposed in the rectifying/smoothing circuit.

Switching power supply

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. In operation, a pump-type applicator is connected to the ball socket connector and is operated to direct a regulated flow of mastic material to the spherical cavity which, in turn, is directed through the manifold to the vertical channels of the front walls for simultaneous deposition of a bead of mastic material along each of the two adjoining wall board sections as the tool is moved in the vertical direction along the outside corner.

Outside corner finishing tool

A corner finisher spreads mastic on a joint formed at an inside corner of drywall. The drywall corner finisher is conventionally used with a plurality of alternative tools for supplying a plurality of coats of mastic in different thicknesses. Therefore, a quick disconnect coupler is provided to rapidly change the tools and yet to hold them so securely that there is almost no chance for an unwanted disconnect between the drywall corner finisher and one of the alternative tools for supplying mastic. The invention provides such a coupler in the form of a ball and socket behind a sliding locking plate having a key hole slot in it for receiving a ball on a mastic delivery device.

Corner finisher tool for applying mastic

A corner finishing tool for use in drywall finishing that consists of wings spreading from a center ridge that is configured to cut through drywall compound ("mud") on a wall corner, the wings including mud dams formed on their wall engaging faces to smooth tops from the mud and to spread a mud impregnated tape in from that wall joint and to direct excess mud into a space formed by that ridge, the dams and a flange projecting rearwardly from the peripheral edges of the wings.

Corner finishing tool

An improved corner finishing tool for applying mastic along a wall joint and having a container that defines a cavity open in two convergent and substantially perpendicular planes, said cavity being bordered by surfaces that converge peripherally of said cavity, said container means comprising a pair of rigid retainer plates joined together by a pair of spring loaded hinges or fasteners and biased to a position of resilient flex. A pair of lever arms pivotally secured to an edge portion of the retainer plates and pivotally joined together at one end are acted upon by leaf springs which engage the lever arms at selected positions relative to the pivotal connection for adjusting the resilient flex between the pair of retainer plates. Mastic material is fed into the cavity through a socket bracket that is mounted to one of the retainer plates to which there is also mounted an alignment wheel.

A corner tool for applying mastic material to an external corner formed by two walls which come together at approximately 90°, 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.

Exterior corner tool

The corner tool (10) is for applying mastic material along a wall joint. It has a frame (12) including an angled plate (12a, 12b), elastically joined at one corner. The frame includes a pair of L-shaped elements, (13, 14) each fastened to one side of the plate, one side and element being elastically movable. There is a pair of brushing blades (16) along intersecting frame element edges. An extensible connection provides adjustment of the sides' elastic bending, and another device elastically prestresses the frame elements, to enlarge the enclosed angle, while another limits the extension movement.

Mastic applicator for wall joint corner - has elastically adjustable sides and frame pieces mounted on open holder

The apparatus is for spreading mastic on a corner formed by a pair of outside surfaces intersecting at right-angles. A spreading head (12) is detachably mounted on a wedge-shaped mastic container (24). A pivoted flap (30) in the container (24) acts as a piston, forcing material through the opening (26) into the hollow spreading head (12). The mastic emerges through an opening (42) shaped to fit the 90 deg. corner. The upper edge of the opening (42) is formed by a plate (16) with indentations (54) in its edge for screeding. The lower end of the mastic container has a bracket (64) with rollers (60) to maintain a constant clearance from the wall surfaces.
