Abstract
Abstract Flow-coating apparatus comprising an open conveyor means for conveying an article to be coated over a gravity-fed spray nozzle positioned below the conveyor and above a sump for collecting the coating material issuing from the nozzle. The nozzle is designed to provide a continuous spray pattern of an elevation such that it extends upwardly through the conveyor means for contacting the article. A deflector is provided for intercepting the sprayed material before it passes through the conveyor and directing it into the sump except during those periods when the article to be coated is within the spray pattern.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
148 words
An automatic flow-coating apparatus for flow coating a surface of an article with a coating material comprising: a spray manifold including a plurality of nozzles for providing a continuous upwardly-directed spray of coating material supplied to said nozzle; a coating material reservoir positioned above said manifold for gravity feeding coating material to said manifold; a sump below said manifold for collecting coating material flowing from said manifold and means for returning material from said sump to said reservoir; conveyor means for supporting an article for movement over said manifold and through the sprayed material; and deflector means movable between a first position and the path of said material flowing from said nozzles and a second position out of the path; and means responsive to the positioning of said article in a position to be contacted by the sprayed material for moving said deflector means to said second position.
Claim 2
Dependent Claim
148 words
An automatic flow-coating apparatus for flow coating a surface of an article with a coating material comprising: a spray manifold including a plurality of nozzles for providing a continuous upwardly-directed spray of coating material supplied to said nozzle; a coating material reservoir positioned above said manifold for gravity feeding coating material to said manifold; a sump below said manifold for collecting coating material flowing from said manifold and means for returning material from said sump to said reservoir; conveyor means for supporting an article for movement over said manifold and through the sprayed material; and deflector means movable between a first position and the path of said material flowing from said nozzles and a second position out of the path; and means responsive to the positioning of said article in a position to be contacted by the sprayed material for moving said deflector means to said second position.
Claim 3
Dependent Claim
33 words
Apparatus according to claim 1 in which said manifold comprises a cylindrical body including said nozzles and said deflector means is an arcuate plate pivotally supported on the ends of said cylindrical body.
Claim 4
Dependent Claim
170 words
An automic flow-coating apparatus for flow coating a surface of an article with a coating material comprising: a spray manifold including a horizontally disposed cylindrical body having a plurality of nozzles in the upper surface thereof for providing a plurality of upwardly directed streams forming a spray of the material supplied to said nozzle; a coating material reservoir positioned above said manifold for gravity feeding coating material to said manifold; a sump below said manifold for collecting coating material flowing from said manifold and means for returning material from said sump to said reservoir; conveyor means for supporting an article for movement over said manifold and through the sprayed material; and a deflector plate below said conveyor means and movable between a first position in the path of said material flowing from said nozzles and a second position out of the path; and means responsive to the movement of said article into a position to be contacted by the sprayed material for moving said deflector plate to said second position.
Claim 5
Dependent Claim
170 words
An automic flow-coating apparatus for flow coating a surface of an article with a coating material comprising: a spray manifold including a horizontally disposed cylindrical body having a plurality of nozzles in the upper surface thereof for providing a plurality of upwardly directed streams forming a spray of the material supplied to said nozzle; a coating material reservoir positioned above said manifold for gravity feeding coating material to said manifold; a sump below said manifold for collecting coating material flowing from said manifold and means for returning material from said sump to said reservoir; conveyor means for supporting an article for movement over said manifold and through the sprayed material; and a deflector plate below said conveyor means and movable between a first position in the path of said material flowing from said nozzles and a second position out of the path; and means responsive to the movement of said article into a position to be contacted by the sprayed material for moving said deflector plate to said second position.
Claim 6
Dependent Claim
25 words
Apparatus according to claim 3 in which said deflector plate is of arcuate shape and is pivotally supported on the ends of said cylindrical body.
