Abstract
A proportioning device having two elongated members which are uncouplably joined at a pivotable joint which may be at various predetermined positions. Both ends of both of the elongated members terminate at pointers, and the pointers at at least one pair of corresponding ends are adjustable. By variation of the pivot point and the position of the adjustable pointer, it is possible to obtain a wide range of ratios of lengths between the pivotable joint and the pointers at the two ends of the elongated members. The device can be used to transfer a series of proportioned dimensions from an original object to an image or reproduction.
