Appl. No.:

Inventors:

Michael Switzer - Columbia SC, US

International Classification:

B61B013/00

US Classification:

186004000

Abstract:

The hand sink portion of this ice cream cart easily connects and disconnects from the dipping cabinet at the ″ tube connection under the ball valve at the dipping well and at the large gray PVC coupler connecting the wastewater line just inside the left door of the sink cabinet. When disconnected, the ″ dipping well tubing curls back up and stays inside the sink cabinet and the ends of the 1″ clear wastewater tubing stick together to form a large ring and fit under the bracket at the top of the dipping well on the dipping cabinet. This easy detachability, separateness, and mobility between the dipping cabinet and the sink cabinet is what makes this cart new and unique.
