19,588. Jupitz, A. May 11, [date applied for under Patents Act, A.D. 1901]. Compasses, drawing. - The proportional compasses shown in Figs. 1 and 2 give three points such that the middle point divides the distance between the outside points in extreme and mean ratio. The compasses are specially arranged for anatomical purposes, such as the reproduction of models upon different scales, by having the points i, k, l protected by fixed knobs. There are pin-joints at c, d, k and a set-screw at g to clamp the instrument.
