Abstract

The drawing board has its scale supporting arm (3) carried by a carriage (2) which travels along the top edge of the board (1) with rollers in contact with the edge and rollers at right angles, in contact with the face of the board. A belt and pulley system keeps the travelling arm in its correct alignment. The remaining belt and pulley drive has an upper pulley (25) fixed to the carriage (2) and a free pulley (20) at the bottom, and the two long links (17, 18) of the parallelogram are attached at the bottom to pivots (21, 22) on the free pulley and are attached at the top to the ends of a short cross member (19) attached to the board.
