A free turning chilling wheel assembly for use with a hot melt dispenser affording quick disassembly for cleaning, inspection, repair or replacement, and having an outer ring with an inner bronze bearing to rotate about a stationary inner cooling chamber, which is sealed to avoid wear and leaks. The outer ring is chilled by fluid flowing through the chamber and the sides of the outer ring are shielded by shielding washers to avoid adhesive building up on the bearing surfaces and ends.

[ What is claimed is:] [1.]1. A chill wheel assembly for use on an adhesive applicator comprising:a) a shaft having an inboard end with a face, and an extended end portion extending from said face and having a proximal end at said face and a distal end, said extended end portion having a section of reduced diameter between the proximal end and the distal end portion and having means for forming passageways through the inboard end affording communication between the space formed by the reduced section and the proximal end of said shaft;b) a first washer positioned over the extended end portion and against said face of said inboard end;c) a cylindrical stator sleeve, having an outer cylindrical surface and an inner cylindrical surface, placed over said extended end portion to cover said reduced section of said extended end portion for forming a chamber;d) an outer ring having an external cylindrical surface and an internal bore,e) a cylindrical member fitted within said internal bore having an internal diameter placed to fit closely about the outer surface of said stator sleeve an rotatably support said outer ring;f) a second washer positioned over said distal end of said extended end portion and against said outer ring; andg) means for retaining said second washer on said distal end.
