ABSTRACT:
A dispenser for multiple rolls of web material such as paper toweling that is provided with dispensing mechanism to lead a web of material out of the dispenser to the user has supports for rotatably supporting rolls in primary and reserve positions, respectively, with transfer mechanism interactive with such roll supports and the dispensing mechanism to automatically transfer web feed from one roll to the other under predetermined sensed conditions. The transfer mechanism includes a pivotally mounted transfer frame swingable to be out of the way to facilitate dispenser loading with the dispenser cabinet cover open, the transfer frame being releasibly retained out of the way in conjunction with dispenser loading, and movable to a sensing location upon closure of the cabinet cover whereat depletion of web material supplied from the roll in the primary position is sensed whereafter the frame again shifts for tucking fingers on the transfer frame to press a web end portion of the reserve roll web material into the dispensing mechanism to thereafter feed web material from such reserve roll. A keeper bracket loosely receives this web end portion incident dispenser loading with the action of cabinet cover closing causing the bracket to firmly grip such portion until the transfer mechanism coacts with the dispensing mechanism to thereafter feed web material supplied from the reserve roll.
