  • Patent number: 4811576
    Abstract: Animal pelts of varying sizes are stretched on a hoop made of a single length of elongated resilient metal bar formed into a circular shape with its ends overlapping in a portion of its circumference. One end of the bar is terminated with a swivelled clamp comprising a toroidal guide through which the adjacent overlapping section of the hoop passes and through the side of which a screw having a T-handle is passed to engage and clamp the hoop. The other end of the bar is terminated with a swivelled, toroidal guide through which passes the adjacent overlapping section of the hoop. One or more flexible, tubular retainers are positioned between the two ends over both adjacent overlapping sections of the hoop to prevent warping.
