ABSTRACT:
A horizontal mount is provided having opposite side portions and central structure for attaching the lower end of an elongated upstanding support member thereto disposed generally normal to a plane extending between and along the mount opposite side portions. A pair of depending arms are provided and pivot structure pivotally supports the upper end portions of the support arms from corresponding opposite side portions of the mount for independent swinging of the arms about generally parallel axes extending along the mount opposite side portions between extended downwardly and outwardly divergent positons and retracted generally parallel positions disposed generally normal to the aforementioned plane. The free end portions of the arms have fluted rollers journaled therefrom for rotation about axes generally paralleling the first mentioned axes and spring structure is operatively connected between the arms independent of the mount yieldingly biasing the arms toward the extended positions thereof. A pair of opposite marginal edge portions of the mount extend between corresponding ends of the aforementioned opposite side portions of the mount and include limit structures for limiting swinging movement of the arms toward their extended and retracted positions. The fluted rollers comprise cylidrical hubs having longitudinally extending generally radial blades secured to the outer surfaces thereof with the outer longitudinal edges of the blades sharpened.
