Sept. 8, 1930, No. 26833. Convention date, Sept. 24, 1929. [Class 97 (ii).] A position-finding instrument having a single telescope adapted to be directed at a celestial body is characterized by the provision of a mounting for the telescope, and a connection between the telescope and the mounting such that the relative orientation of the telescope and the mounting is indicative of the declination of the celestial body. The mounting is movable with respect to a frame, the relative movement being indicative of the hour angle, while the frame is movable with respect to a support, the relative movement being indicative of latitude. As shown in Fig. 2, a telescope 1 moves over a declination scale 16, while a tube 9 perpendicular to the telescope 1 has a section 13 perpendicular to it and axially rotatable about the hour angle arc 15. At right-angles to the tube 14 coaxial with the tube 13 is a tube 19 rotatable about the latitude arc 20 and containing a spirit level 27 with transparent cover glasses, through which light passes, as shown in Fig. 9, through the negative lens 23, to the prisms 18, 17, along the tubes 14, 13, Fig. 2, to the prism 12, and up the tube 9 to the prism 8 and the eyepiece 3 of the telescope 1. The centre of the spirit level 27 is always centred with the cross-hairs 6 in the telescope 1. A horizon type of level, Fig. 11, comprises mirrors or total reflection prisms 50 for sighting on two points of the horizon preferably 90‹ apart. The perpendicular to these surfaces can be set by screws 51 with respect to the levelling device itself by an amount equal to the dip of the horizon. The optical arrangements superimpose an image of either type of levelling device on the image of the celestial body under observation.
