Dispenser for flexible sheet material
First Claim
1. A dispenser for a plurality of dispensing rolls of flexible sheet material comprising:
- a chassis;
a dispensing roll transfer structure including means forming opposed guide channels on opposite sides of said chassis operative to receive the axial ends of a first dispensing roll in a sheet-dispensing position and a second dispensing roll in a reserve position thereabove, both said dispensing rolls being movable by gravity downwardly in said guide channels;
said guide channel-forming means including a guide track member mounted for pivotal movement between a support position for vertically supporting said second roll when said first roll is in a sheet-dispensing condition and a release position in which said second roll is released for movement to said sheet-dispensing position when said first dispensing roll is in a depleted condition; and
a gauging roll extending between opposite sides of said chassis substantially parallel to the axis of said dispensing rolls, said gauging roll being journalled for rotation on a substantially fixed axis and being disposed with respect to said guide channel-forming means to engage only a dispensing roll in its sheet material dispensing position to provide vertical support therefor when said dispensing roll contains sheet material thereon and to permit passage of the supported dispensing roll from said guide channel forming means when said sheet material is depleted therefrom.

Abstract
A dispenser for flexible sheet material rolls in which a first roll is supported in a dispensing position, a second roll is supported in a reserve position and a roll transfer apparatus is operative to transfer the second roll to the dispensing position upon depletion of sheet material from the first roll with the supporting arrangement for the roll in the dispensing postion being rotatable with such roll and thereby subject to significantly reduced friction effects. The described dispenser organization also includes a novel arrangement for retaining the cores and spindles of spent rolls within the dispenser until the closure cover is opened for replenishing the dispenser with fresh rolls whereupon, by opening the cover, the spent residual roll elements are automatically deposited into the opened cover that forms a receptacle from whence the elements can be retrieved for disposal and following which the dispenser organization is automatically returned to its operative condition in a single step upon simply closing the closure cover.

14. A dispenser for a plurality of dispensing rolls of flexible sheet material having spindle means extending beyond opposite ends thereof, comprising:
-
a chassis having a sheet dispensing opening in one face thereof; a dispensing roll transfer structure including mutually spaced guide track members forming substantially vertically extending, open ended guide channels on opposite sides of said chassis for reception of said spindle means and for gravitationally induced guided movement therealong between an elevated reserve position and a subjacent sheet-dispensing position; and a gauging roll extending between opposite sides of said chassis substantially parallel to the axis of said dispensing rolls, said gauging roll being journalled for rotation on a substantially fixed axis and being disposed with respect to said guide channel-forming means to engage only a dispensing roll in its sheet material dispensing position to provide vertical support therefor when said dispensing roll contains sheet material thereon and to permit passage of the supported dispensing roll from said guide channel forming means when said sheet material is depleted therefrom; at least one of said guide track members being mounted for pivotal movement to place the upper end thereof in a position of subjacent vertically supporting engagement with a spindle means of a dispensing roll in said reserve position when said spindle means of said dispensing roll is retained in said sheet dispensing position by said gauging roll and a release position displaced from said position of engagement when said spindle means of said dispensing roll moves by gravity from said sheet dispensing position to fall from the open lower ends of said guide channels. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A dispenser for sheet material from dispensing rolls having residual elements for disposal following dissipation of said sheet material from said rolls, said dispenser comprising:
-
a chassis having a dispensing roll transfer structure from which residual elements of dissipated dispensing rolls are discharged, when spent; means forming a compartment in the bottom of said chassis for receiving said discharged residual roll elements; a closure cover pivotally attached to said chassis for movement between an open and a closed position thereon; a door movable independently of movement of said closure cover operably connected to said chassis for releasably closing said compartment; a releasable latch for holding said door in its compartment-closing condition; and first means on said closure cover for impacting said door to release said latch for opening said door upon moving said closure cover to its open position. - View Dependent Claims (23, 24, 25, 26)

27. A method for dispensing sheet material in a dispenser from rolls in which said sheet material is wound on a core, said dispenser including a movable closure cover enclosing said rolls and a collection area closed by releasably latched door movable independently of the movement of the closure cover, comprising the steps of:
-
supporting a first roll in a dispensing position and a second roll in a reserve position; dispensing sheet material from said first roll; upon depletion of sheet material from said first roll, releasing the core thereof to a collection area and said second roll to said dispensing position; dispensing sheet material from said second roll; upon depletion of sheet material from said second roll releasing the core thereof to said collection area in said dispenser; and moving said closure cover toward a position for replenishing said rolls and thereby impacting said door for releasing a latched connection between said door and said dispenser to effect movement of said door to an open condition for discharging said cores from said collection area. - View Dependent Claims (28, 29, 30, 31)
