Abstract

27,613. Lyon, C. Dec 15. Theodolites.-Relates to means for measuring angles by means of a telescope designed for the observation of gun fire, but which can be adapted to any telescope. An " observation of fire " telescope is mounted on a socket c, joined to an axle passing through the centre of a horizontal table a and loose graduated disc h, so as to be movable in horizontal and vertical planes. A pointer f, moving over a graduated scale g and attached to one of the trunnions d<1>, indicates angular elevation. To determine the horizontal angular distance between two objects, the telescope is directed at one, and the loose graduated disc h is clamped so that a pointer i, attached to the socket c, points to zero. When the telescope is directed at the other object, the angular horizontal distance is indicated by the pointer i.
