Abstract
Abstract Groove coating apparatus includes a block-like device adapted to ride within a groove. The device has a coating material receiving chamber, a dispensing aperture at a forward portion of the block within the groove. The following portion of the block is configured to dispense the dispersed coating material onto the side walls of the groove. Means bias the dispersing means onto the bottom wall of the groove.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
222 words
An apparatus for coating the walls of a groove in a wall panel with a coating material comprising; a support structure; flow means connected to said support structure and effective to cause said coating material to flow into said groove, said flow means comprising a first member defining a chamber for containing said coating material and having an opening adapted to be positioned over said groove, and pump means connected to said member and effective to deliver said coating material to said chamber and out of said opening; dispersing means adapted to extend into said groove and effective to disperse the coating material within said groove after it is caused to flow thereinto, said dispersing means comprising a second member positioned adjacent said first member and having a part adapted to extend below the side walls of said groove, and engage the lower wall of said groove, said part having a width dimension less than the distance between said side walls and; spring means connected to said support structure and to said first member and said second member and adapted to resiliently support said first member and said second member over said groove whereby the position of said dispersing part of said second member is adjusted to the height of the lower wall of said groove during the opeation of said apparatus.
