Abstract: A nailing apparatus in which a pair of guns are supported on a carriage in side-by-side relationship to permit nailing edges of adjacent panels with controlled nail spacing and penetration.

Abstract: A hand operated dry wall taping tool includes a tubular main body portion, to be held by the operator, with a tape applicator head portion at one end thereof. The tool is supplied with dry wall tape cement from a supply thereof under pressure. A supply roll of dry wall tape is carried from the main body of the applicator, the tape is fed through the applicator head onto the wall joint to be taped. In the applicator head, a pair of tape drive wheel portions engage the tape and press it against the wall for taping a seam between two adjacent sections of dry wall. As the drive wheels pull the tape through the applicator head, dry wall cement is applied by the applicator head to the side of the tape which is to engage the wall. In one embodiment, a spring biased swivel roller presses the cement laden tape into engagement with the wall as the tape is applied to the seam.

Abstract: In a corner roller tool for rolling mud laden applied tape into a corner dry wall seam, a pair of tandem rollers are provided for rolling the creased tape into the corner seam and for squeezing out excess mud from beneath the tape. The rollers each comprise a wheel having a tread portion of generally V-shaped radial cross section. The included angle .theta. between the opposed faces of the V-shaped tread portion is approximately 90.degree. for pressing the tape into firm engagement with the side walls of the corner seam. The corner roller wheels are carried from a frame which is pivotably coupled to a elongated handle. The handle is pivotable in at least two orthogonal directions to facilitate rolling of the tape into the corner seam when the operator can not face directly into the seam. The corner roller wheel are free to move laterally on their respective axles to facilitate tracking of imperfect seams. The included angle between the tread face portions of the two wheels are preferably larger than 90.

Abstract: A hand operated dry wall taping machine includes an elongated tubular body, to be held by the operator, having a tape applicator head portion at the end thereof adjacent the seam being taped. A supply roll of tape is carried from the tubular body. The applicator head includes a dry wall cement dispensing box through which the dry wall tape is fed. Cement is dispensed onto the side of the tape which is to face the wall being taped. A rotary tape shear is disposed up-tape from the cement dispensing box. A thumb actuated pneumatically operated cylinder actuates the rotary shear at the end of the seam being taped and advances a short length of tape through the cement dispensing box in readiness to commence taping of the next seam. A whisker valve in an air line is actuated by the pneumatically operated cylinder for delivering a momentary blast of air into the cement dispensing box for feeding mud onto the advanced leading end of the sheared tape.

Abstract: A hand operated dry wall taping machine includes an elongated tubular main body portion to be held by the operator. A tape applicator head portion is disposed at the end of the machine adjacent the seam being taped. A supply roll of tape is carried from the tubular body. The applicator head includes a dry wall cement dispensing box through which the dry wall tape is fed. Cement is disposed from the box onto the side of the tape which is to face the wall being taped. A pair of tape drive wheels are carried forwardly of the tape dispensing box to engage the marginal side edges of the tape, to press the cement laden tape against the wall and to pull the tape from the supply roll through the applicator head and cement dispensing box. A quick disconnect couples the cement dispensing box and tape drive wheel assembly to the applicator head for ease of removal for cleaning. A slidable cover of the cement dispensing box is adjustable for controlling the thickness of the layer of cement deposited upon the tape.
