Abstract
Abstract A device, to apply a tape and covering finish plaster to a dry wall seam in a single pass lengthwise thereover, comprising a relatively light weight, hand-supported frame, a unit on the frame operative--upon predetermined manipulation of the frame--to first apply glue to a length of the tape and then glue-affix the tape to the dry wall over said seam, and another unit on the frame operative-- upon such manipulation of the frame, and in conjunction with but trailing the tape gluing and applying unit--to apply a thin, smooth, layer of plaster (known as "mud") over the then-in-place tape.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
258 words
A dry wall taping device, comprising a hand-supported and manipulated frame having a handle portion at a first end and a tape applying end portion at a second opposite end for projection by an operator into close proximity to a dry wall having a seam, for applying glue to a dry wall tape, securing the glued tape to a dry wall and plastering over the secured tape in generally immediate succession, and including means to support a roll of tape in position for the tape to pay out and run to the tape applying end of the frame, means intermediate the tape roll support and the tape applying end to apply glue to at least one side of said run of tape, a transverse axis tape applying roller at the tape applying end of the frame, means mounting the roller in position to engage said run of tape to roller-pressure glue-affix the tape over a seam upon dry wall traversing motion imparted to the frame by said operator and attendant paying out of said tape, a plaster extruding and smoothing head means for applying a layer of plaster of a predetermined controlled thickness at the tape applying end of the frame, means mounting said head means in connection with the frame whereby said head--when pressure-fed with plaster, and upon traversing motion of the frame--applies and smooths, in trailing relation to the tape applying roller, a finish layer of plaster over the glue-affixed tape, and means in part on the frame to feed plaster under pressure to said head.
Claim 2
Dependent Claim
258 words
A dry wall taping device, comprising a hand-supported and manipulated frame having a handle portion at a first end and a tape applying end portion at a second opposite end for projection by an operator into close proximity to a dry wall having a seam, for applying glue to a dry wall tape, securing the glued tape to a dry wall and plastering over the secured tape in generally immediate succession, and including means to support a roll of tape in position for the tape to pay out and run to the tape applying end of the frame, means intermediate the tape roll support and the tape applying end to apply glue to at least one side of said run of tape, a transverse axis tape applying roller at the tape applying end of the frame, means mounting the roller in position to engage said run of tape to roller-pressure glue-affix the tape over a seam upon dry wall traversing motion imparted to the frame by said operator and attendant paying out of said tape, a plaster extruding and smoothing head means for applying a layer of plaster of a predetermined controlled thickness at the tape applying end of the frame, means mounting said head means in connection with the frame whereby said head--when pressure-fed with plaster, and upon traversing motion of the frame--applies and smooths, in trailing relation to the tape applying roller, a finish layer of plaster over the glue-affixed tape, and means in part on the frame to feed plaster under pressure to said head.
Claim 3
Dependent Claim
37 words
A dry wall taping device, as in claim 1, in which the frame is elongated; there being one hand grip at the first end of the frame, and another hand grip intermediate the ends of said frame.
Claim 4
Dependent Claim
74 words
A dry wall taping device, as in claim 1, including a housing on the frame, the run of tape passing through the housing, and the glue-applying means being disposed in the housing and comprising a glue applying roller journaled in said housing beneath but in engagement with the tape, and a glue well in the housing; the roller, whose lower portion extends into the glue well, being rotated by said passing run of tape.
Claim 5
Dependent Claim
42 words
A dry wall taping device, as in claim 3, including a normally inactive, tape cut-off knife unit mounted in the housing intermediate the glue-applying roller and the tape applying roller, and means operative to actuate said knife unit to sever the tape.
Claim 6
Dependent Claim
41 words
A dry wall taping device, as in claim 4, including a hand grip on the frame; said knife unit actuating means including a, longitudinally movable pull element, and a handle on such pull element adjacent and finger-accessible from the hand grip.
Claim 7
Dependent Claim
76 words
A dry wall taping device, as in claim 3, including a tape hold-down roller journaled in the housing in parallel relation above the glue-applying roller and bearing in contact with the run of tape engaged thereby; there being manually actuated means, operative from exteriorly of the housing, to rotate the glue-applying roller in a direction to advance said run of tape a distance beyond the housing toward said second end preparatory to a seam taping operation.
Claim 8
Dependent Claim
51 words
A dry wall taping device, as in claim 1, including a transverse shaft secured on the second end of the frame; the tape applying roller mounting means comprising, with said transverse shaft, spaced radial projecting arms, and the tape applying roller spanning between and being journaled in connection with such arms.
Claim 9
Dependent Claim
37 words
A dry wall taping device, as in claim 7, in which the head-mounting means comprises, with said transverse shaft, spaced radial arms and the head spanning between and being journaled in connection with such last-named radial arms.
Claim 10
Dependent Claim
64 words
A dry wall taping device, as in claim 8, in which the transverse shaft is journaled for turning about its axis; there being a radial lever secured to the shaft, and hand-actuated means to impart movement to such lever whereby to turn the transverse shaft in a direction to cause the roller and head to assume proper relative positions for proper dry wall engagement.
Claim 11
Dependent Claim
48 words
A dry wall taping device, as in claim 9, including a hand grip on the frame; such hand-actuated means including a pull element connected to the lever and extending to adjacent the hand grip, and a handle on the pull element adjacent, and fingeraccessible from, the hand grip.
Claim 12
Dependent Claim
51 words
A dry wall taping device, as in claim 1, in which the plaster extruding and smoothing head means is hollow and flat faced; there being a horizontal slot, in said flat face, for extrusion of the plaster and gauge wheels carried by said head means for engagement with a dry wall.
Claim 13
Dependent Claim
59 words
A dry wall taping device, as in claim 1, in which the plaster extruding and smoothing head means is hollow and formed with a slot for extrusion of the plaster; the plaster-feeding means including a conduit extending along the frame, a hand valve in the conduit, and a flexible hose connected in communication between the conduit and said head.
