Abstract

The draughtman's scales (7) are attached to a vertical strut (5) which is pushed across the drawing surface on the board. This strut being attached to a carriage (3) which travels across the top of the board. The accuracy of alignment of the scales is ensured by a double parallelogram linkage attached to the two points on the carriage and to two points at the top of the rear face of the board so that the carriage travels away from them to the end positions.
