  • Patent number: 4856724
    Abstract: A dispenser for rolls of flexible sheet material wound on cores is disclosed. The dispenser holds multiple rolls and includes guide tracks for guiding the rolls through the dispenser. A holding lever pivotably connected to each side of the dispenser selectively holds the rolls in position in the dispenser and has its pivoting motion controlled by a sensing plate which contacts a lower dispensing roll to sense when the sheet material is substantially depleted. The lower dispensing roll is always held out of contact with rolls of a dispensing mechanism, in one embodiment initially by a transfer roller and thereafter at a constant vertical axis by the holding levers and, in another embodiment by the holding levers alone. A shield is located between the roll surface of the lower dispensing roll and the rollers of the dispensing mechanism.
