Abstract:
This device consists of a pair of crossed wooden sticks joined together at their intersection with a single screw. Thus either stick may be rotated toward or away from the other. Along each stick short brads should be driven at equal distances, and rubber bands stretched between those having alternate positions on the sides of each of the angles.
