Roll supporting and automatic dismounting mechanism for roll towel

Abstract

A rotatable first roll end holder has diametrically opposed pins radially surrounded and projecting axially from radial surfaces except at pin inner radial extremities where a recess extends radially between the pins and opens axially toward the roll to be supported. The recess preferably also opens radially at opposite sides of the first holder. A second roll end holder may consist of merely a central projection so that a roll of toweling may be supported between said holders by simultaneous axially engagement of the pins and central projection. When sufficient toweling is dispensed from the roll to the pin inner radial extremities, the roll is released radially by the pins and pivots about the second holder projection through the first holder recess for ultimate complete disengagement from the holder. The first holder may be rotatably secured to a support axially pivotal about a vertical axis and a finger projection may be formed on the first holder as an extension of the recess with counterweighting of the first holder urging the holder to rotate with the finger projection extending horizontally and thereby permitting axial finger pressure against the finger projection to axially pivot the first and its support away from roll end engagement position to permit such engagement. Also, a circumferentially extending, axial projection extending circumferentially less than one-half a circumference may be on the second holder axially received in a circumferential groove of the roll radially outwardly of the second holder central projection to adapt the holder combination to different configurations of roll ends.
