Abstract

30,319. Melvill, E. H. V. Dec. 28. Angle - measuring instruments; surveying- instruments; levelling heads. - Comprises improvements in surveying-instruments using the same graduated circle for measuring both vertical and horizontal angles. The limb 1 is formed with a threaded socket 2 for securing it to its support, and carries the alidade 3, provided with levels 17, 18 at right-angles for setting the limb and alidade horizontal, and a perpendicular level 19 for vertical setting. A magnetic compass 21 is also fitted to the alidade. When in use as a clinometer for setting on inclined surfaces, a fiduciary surface 23 is attached to the limb, in such a manner that, when the reading is zero, the surface is parallel with the line of sight. The support comprises a base-plate 24 and a levelling-plate 26 adjusted by screws 27. The plate 26 carries the socket 30 provided with a level 32, and at its upper end with a ball-and-socket joint 34. A slot 35 at one side of the joint permits the ball and fittings above it to turn through an angle not less than 90 degrees. The ball 34 carries a socket 37 supporting the limb 1 to facilitate orientation. The alidade may thus be placed at any angle to the horizontal. A sighting-telescope 40 is positioned about the level of the alidade and eccentric to it, and is pivoted to revolve in a vertical plane.
