Abstract

25,073. Paynter, P. J. Nov. 17. Dividers ; dividing-instruments. - A pair of dividers is fitted with a middle pointer C, which slides through the joint and also between the ends of equal links B, pivoted to the legs A. As the dividers are opened, the pointer C always divides equally the angle between the legs, For taking off chart distances, a jointed pointer D is fitted to turn and slide on the pointer C.
