Abstract
Multiple image L-shaped eye-pieces for dial clinometer compasses. Eccentric eye-piece mounted on the side of a dial compass with shock-absorbing liquid and the zero of the graduation shifted 90 degree from magnetic North, whose optical axis is normal to the radius that passes through this zero bearing. This consists of a split-image magnifier in whose diametric area there is a slit collimator and the half-magnifiers respectively magnify the images reflected at 90 degree of a spherical level and of the reading on the graduated circle. Attached to the base there is a pendular dial clinometer with reading via a Stanhope magnifier with double eye-piece on a 90 degree beam-splitter prism. It enables the collimation of any object in a vertical plane from 0 degree to plus or minus 90 degree and, simultaneously, viewing the centring of the level and the reading of the heading and, by means of the double eye-piece of the clinometer that of any topographic or parietal stratigraphic slope. Applicable in quick surveying and geology.
