  • Patent number: 5170982
    Abstract: A holder for sheet-like material provides a base defining a vertically oriented channel carrying a dense sphere to contact a spacedly adjacent holding arm to hold sheet-like material between the ball and the holding arm. The channel carrying the ball has a curvilinear surface most distal from the holding arm to move the ball closer to the fastening arm as the ball moves downwardly in the channel. The ball is of such size that it is prevented from passing from the lower end of the channel by the holding arm. Sheet material moved in an upward direction between the ball and fastening arm is held from moving downwardly by reason of frictional contact with the ball and holding arm, but may be removed from the holder by moving the material in an upwardly angulated direction which releases the holding friction.
