  • Patent number: 4819887
    Abstract: A rack for supporting a plurality of rolls of sheet material particularly floor covering is defined by a frame structure carrying two chains one at each end with the chains arranged to rotate around upper and lower chain wheels. The chains rotate in synchronism with support hooks carried on the chains and aligned transversely of the chains. A bar can be hooked onto the support hooks to receive a roll of the floor covering. The bar can be lifted into place by a lift mechanism in the form of an elongate bar with an upper and lower hook so the upper hook can engage over a previous bar and a lower hook can lift the intended bar to a position adjacent its receiving hook. An overcenter linkage then is used to reduce the length of the bar to lift the new bar into engagement with its respective hook.

  • Patent number: 4809921
    Abstract: A device for measuring and re-rolling floor covering material, particularly carpet comprises a base member having sides and a transverse table top. On each side of the table top is mounted a cradle which extends downwardly from the table top and outwardly to the side of the device. Each cradle is formed by four rollers, two of which are carried directly on the base and two of which are cantilevered outwardly therefrom and are pivotally moveable inwardly to a retracted position. The re-roll cradle allows two of the rollers to pivot about the axis of the next adjacent roller so that the rollers can be folded inwardly to form a confined space acting to commence the re-rolling of a carpet edge. A knife is carried on a chain movable across the table top and includes guide wheels which hold the carpet down onto the knife blade.
