1,012,207. Mathematical drawing-appliances. F. FORSTER. Oct. 5, 1964 [Oct. 3, 1963], No. 40611/64. Heading B6P. A base rail 1 carries a drawing board 2 comprising metal ledges and a wooden plate 6 over which can be moved, by means of handles 8 on rollers 7. an endless cloth 9 with a sheet of drawing paper secured thereto. Mounted on the rail 1 for pivotal movement about its longitudinal axis is a guide rail 3 on which are slidable carriers 23, 24, 25, the carriers 23, 25 being connected by a distance rail 27. Pivotally mounted on the carriers is a system of levers constituting a pantograph and a parallelogram, supported by rollers 39, 61. Adjustable in a slot 37 is a train peg 38, while a drawing head 47 is mounted on the link 44 and carries a revolving head 49 provided with four pencils 48 for selective use. The pencil and tracer can be raised from the paper by the action of a pneumatic piston on compressing a pedal 60. The board 2 and rail 1 are provided with pegs and perforations to allow the board to be mounted as shown or in an alternative position 2<SP>1</SP>, when the pencil and tracer can be interchanged, to produce an. increase in size in the Y direction of a curve in comparison with the curve followed by the tracer. In the first position, the Y-dimension is reduced. The X-dimension is unchanged.
