Drafting-machines.- The straight-edge G is carried on a spindle D having at its ends equal pinions C, C<1> engaging parallel and similar racks B, B<1> attached to the drawing-board A so that a series of parallel lines at right-angles to the board can be drawn. The straight-edge G, or an additional one, may be pivotally attached at one end so that it can be swung around and secured in position for drawing lines at any angle.
