Abstract

14,076. Aarflot, B.. Sept. 22, 1906, [date applied for under Patents Act, 1901]. Protractors.-Relates to an instrument for trisecting an angle H C I. A rule A is laid along one arm of the angle ; to the rule is pivoted at C a second rule B having a third rule G projecting at right-angles from it at K, half-way between C and E; E is a point at which a fourth rule F is pivoted to the rule B, the other end of the fourth rule being pivotally and slidably connected to the first at D, such that CD = CE. The arm B is turned till the rules F, G intersect on the arm C H of the angle. The angle is then trisected by C E.
