ABSTRACT:
A texture material applicator device according to the present invention comprises a barrel for supporting a hollow shaft. The shaft is mounted on bearings for rotation about a central axis and for longitudinal translation along the axis. A supply of compressed air is provided to the shaft. The compressed air is expelled from the front end of the shaft at high speed. A supply of texture material to be applied to a surface is extruded into the barrel from a manifold near the front of the shaft. The shaft is movable longitudinally from an "off" position, in which the stream of expelled air does not strike the texture material, to an "on" position, in which the stream of air does strike the texture material. A trigger member extending through a slot in the barrel is provided so that an operator may control the longitudinal position of the shaft. In addition, the trigger member may rotate about the axis of the shaft. The slot has one or more notches in its side walls for maintaining the trigger member in a selected position without requiring continued operator pressure, allowing continued application of the texture material.
