Sprayer for application of textured finish to surfaces

Abstract

A sprayer for providing a regulated flow of material to a gun includes apparatus for fixing a substantially-cylindrical stator to a circular port of a pump housing block. Such apparatus includes a pair of clips that are pivotally fixed to the exterior of the pump housing block. The clips are diagonally spaced with respect to the port. Apertures are arranged in the pump housing block to receive crimped portions of the clips to engage apertures within the surface of a collar fixed to an end portion of the stator. By fixing the stator to the pump housing block in a manner that is not subject to rotation, rotation of the rotor with respect to adhesive rubber material within the stator when torque is manually applied to the rotor.

1 . Apparatus for fixing an elongated, substantially-cylindrical stator to a pump housing block of a sprayer comprising, in combination:
 a) a collar, said collar being fixed exterior and adjacent an end of said stator;   b) said collar having at least one indentation arranged about the circumference of said stator;   c) at least one clip pivotally engaged to the exterior of said pump housing block;   d) said at least one clip including a crimped portion;   e) at least one aperture in said pump housing block, said aperture being located with respect a clip so that said crimped portion of said pivotally-mounted clip protrudes within the interior of said pump housing block when said clip is rotated to a closed position to engage an indentation of said collar.   
   
   
       2 . Apparatus as defined in  claim 1  further comprising:
 a) a plurality of indentations;   b) a plurality of pivotally-mounted clips; and   c) a plurality of apertures in said pump housing block.   
   
   
       3 . Apparatus as defined in  claim 2  further including:
 a) two pivotally-mounted clips; and   b) two apertures in said pump housing block, each of said apertures being aligned to admit said crimped portion of one of said pivotally-mounted clips.   
   
   
       4 . Apparatus as defined in  claim 3  further characterized in that:
 a) said collar is substantially annular;   b) said pump housing block includes a circular port for receiving said collar; and   c) said clips are spaced diagonally from one another with respect to said circular port of said pump housing block.   
   
   
       5 . Apparatus as defined in  claim 4  wherein said collar comprises molded elastomeric material. 
   
   
       6 . Apparatus as defined in  claim 5  wherein said collar includes four indentations.
