Abstract: A spray applicator to discharge plaster or another texturizing material in a spray pattern against a wall surface or the like. There is a manually operable air cylinder and piston assembly which discharges pressurized air through a first nozzle, with an air jet traveling through an area where the plaster or the material descends from a container, with the air jet carrying some of the plaster through a forward discharge nozzle to cause a spray pattern. There is rotatable fluid discharge nozzle portion which is, by said rotation, moved toward and away from an air discharge nozzle.

Abstract: A dry wall tape applicator where the tape moves through a chamber containing a taping compound and out a dispensing opening to a seam defined by two drywall panels. The dispensing opening is formed in part by an adjustably mounted plate, the position of which is controlled by a rotatable knob having an eccentric actuating stud member engaging a slot of the plate. The plate is held within close tolerances in a slideway so that the dispensing opening defines an accurately controlled slot of uniform width. The bottom wall of the housing has a convex configuration so that when the tape is in close proximity to the bottom wall, there is a proper application of the taping compound to the tape.

There is a rotatable adjusting sleeve which moves the two nozzles further apart or closer together to control the spray pattern and also to close the discharge nozzle.
