摘要： This device is a piece of apparatus which allows the user to execute circumferences with large radii, including radii longer than the apparatus itself, without the need for a support at the centre of curvature. It is capable of making an arc of circumference with a radius of several metres on a small sheet of paper (A4 for example) without the need for any support outside the area of the paper.
It is made up fundamentally of two knurled wheels (1 and 2) linked by an axis (4) which act as moveable supports for a third point consisting of a ball (3) which is able to move in all directions. As it moves the apparatus pulls along a pencil, pen or saw to draw or cut the circumference.
The radius of the circumference can be varied either by moving the bracket (5) for the pencil, pen or saw along a graduated scale (6) attached to the body of the device (7) or, for greater differences, by moving the wheels closer together or further apart. The device may also have groups of several wheels on the same axis which can be moved to allow a greater range of radii to be obtained.
