发明名称 Bottom line work piece holders
摘要 A workpiece such as a paper or a card is held in proper position in a typewriter having a paper scale for typing to the bottom of the workpiece without side slippage by the inventive workpiece holders. Each of the pair of holders mounts fixably, detachably, and slidably flush with the outer surface of the paper scale and has an inner member positioned when mounted such as to be parallel to the outer surface of the paper scale and at a suitable distance out and on each side of the workpiece for free movement of the workpiece between the member and the outer surface of the paper scale.
