Flexible sheet material roll dispensing
First Claim
1. In a dispenser for flexible sheet material having at least one roll of sheet material and mechanism to pass sheet material from the roll out of the dispenser, a method for promoting feeding of sheet material from the roll and out of the dispenser comprising the steps of:
- resting the roll surface on a feed roller;
passing sheet material from the roll between the roll surface and the feed roller to rotate the roll and feed roller incident withdrawal of material from the roll;
guiding downward movement of the roll through an arc spaced from the axis of the feed roller as the roll diameter diminishes incident depletion of material on the roll to increase driving pressure between the roll and feed roller surfaces; and
passing the essentially depleted roll past the feed roller surface of discard.

Abstract
Dispensing flexible sheet material involves mounting at least one roll on dispensing arm means pivotally connected to a dispenser near the lower end of the chassis so that as material on the roll is depleted the concomitant diminishing diameter roll will swing down on the dispensing arm means for the roll axis to move through an arc spaced from the axis of the feed roller to wedge the roll surface firmly against the surface of the feed roller as the axis of the roll moves toward a line extending through the feed roller axis and the pivotal axis where the dispensing arm means is connected to the chassis. When the roll is essentially depleted it swings past the line and the feed roller into a discard area. Dispensing from multiple rolls in succession utilizes an initial roll mounted as above described and a reserve arm means connected to the chassis through means which permits the reserve arm means to move down vertically relative to the chassis as the initial roll is depleted to a lower position where the reserve arm means thereupon pivots relative to the chassis and the reserve roll engages with the feed roller when the essentially depleted initial roll swings into the discard area to swing through an arc similar to that which the initial roll moved through as the roll diameter diminished.

3. A dispenser for flexible sheet material comprising:
-
a chassis adapted to be attached to a wall at a location for sheet material use; a feed roller mounted to rotate near the lower end of said chassis; dispensing arm means pivotally connected to said chassis and having roll mounting means thereon to engage with the ends of and rotatably support a roll of sheet material to locate the roll surface resting on said feed roller, said dispensing arm means acting to guide the roll axis through an arc spaced from the axis of the feed roller as material on the roll is depleted with concomitant diminishing roll diameter to wedge the roll surface firmly against the surface of said feed roller. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. A dispenser for flexible sheet material comprising:
-
a chassis adapted to be attached to a wall at a location for flexible sheet material use; a feed roller operably connected to said chassis and mounted to rotate near the lower end of the chassis; mounting means operably connected to said chassis and engagable with a roll of flexible sheet material to rotatably mount said roll and locate the surface thereof against the surface of said feed roller, said mounting means and feed roller being positioned with respect to each other so that upon removal of the flexible sheet material from said roll, the roll will be wedged against the feed roller. - View Dependent Claims (12)
