Abstract: A hot melt dispensing apparatus for converting solid thermoplastic material to molten thermoplastic material and for dispensing the molten thermoplastic material comprises a solid thermoplastic material receiving hopper, a vibrated feed chute mounted beneath a bottom opening in said hopper, which vibrated feed chute has a discharge opening laterally offset from the vertical plane of the hopper, and a heated reservoir mounted beneath the discharge end of the feed chute. The reservoir is laterally offset from the hopper so that heat rising from the reservoir does not melt solid thermoplastic material contained within the hopper or within the feed chute. The hopper is rectangular in configuration and comprises three vertical walls and one sloping wall angled relative to a bottom discharge opening of the hopper.

Abstract: An applicator assembly for applying hot melt adhesive to a substrate such as the end flaps of a sift-proof carton includes slot nozzles employing elongated, wear-resistant doctor blades formed with a fluid discharge slot. The doctor blades, preferably in the form of hardened steel plates, are releasably clamped to the body of the applicator in communication with the outlet of an internal passageway in the applicator body which receives adhesive from a flow control device such as an adhesive gun. The plates forming the doctor blades are separated by a shim to define the fluid discharge slot into which the adhesive flows from the internal passageway. The lowermost ends of the doctor blades are formed in various configurations to spread the adhesive in the desired pattern or thickness on the substrate depending upon the type of adhesive employed or the requirements of a given application.

Abstract: A dynamoelectric machine includes a two-part brush holding structure, allowing the part not exposed to high heat to be made from an inexpensive material. The two parts are assembled as a friction fit, and includes insulation-displacing connectors for terminating internal wiring and simultaneously providing external connections, some of the connectors protruding through the end bell. A boot member, which may be interchanged, and which sealingly passes a cable, is used to render the machine waterproof.
