Abstract
Abstract A continuous roll towel dispenser including an upper cabinet for housing a clean towel roll and a lower cabinet for housing a used towel roll. The two cabinets are vertically spaced from each other so that a length of towel extending from the clean towel roll in the upper cabinet to the used towel roll in the lower cabinet is exposed between the cabinets. The exposed length of towel between the cabinets is spaced a substantial distance away from the rear walls of the cabinets so that both sides of the exposed length of towel are readily accessible to the user. A first driving roll in the upper cabinet is driven in response to withdrawal of towel from the clean towel roll, and is connected through a chain and sprocket mechanism to a second drive roll in the lower cabinet for automatically driving the used towel roll each time a new length of clean towel is withdrawn. Each of the upper and lower cabinets includes a hinged wall portion for providing access to the towel rolls contained therein. A takeup rod is included in the lower cabinet for automatically drawing any slack towel into the lower cabinet after each driven movement of the used towel roll. A modified embodiment is disclosed in which an actuator must be operated by the user to permit the withdrawal of clean towel, and the length of towel that can be withdrawn following each operation of the actuator is limited to a predetermined length.
