Description

The proposed device, consisting of two transverse straps of rulers parallel to each other and perpendicular to these lintels, of a movable bar, carrying slides movable along it with a stationary limb having a movable alidade rigidly fastened with a ruler with divisions, carrying a microscope The index with a magnifying glass and a spring needle for pricking, aims to provide an opportunity for tenants when working in the field, without calculations, to put on the tablet points of traverse moves along directional corners and distances m.

The drawing of FIG. 1 shows a top view of the device; FIG. 2 shows a section along I-II of FIG. 1 with alidade shifted to 180; FIG. 3 is a section along III-IV of FIG. one.

The device consists of two AB lines (Fig. 1, 2 and 3) fastened with transverse strips with edges beveled inwards and perpendicular to the moving bar OD moving on these rails and on wheel B, which is perpendicular to these rulers. On the board, the DM slides the slide E with the protrusion T, on which the limb Γ is fixed, with divisions from 0 ° to 360 °, having a movable alidade W, tightly fastened with a ruler MN with divisions, equipped with a movable index K with a pole D with a spring needle And for pricking and

microscope D located against the bullet division. The microscope eyewatch O and the needle point are in the straight line of the OR, passing through the center of the limb, in the same vertical plane with the line of sight of the alidade. The center of the limb, combined with the sighting with this firebox on the ground and on the tablet, is at the same time the center of the X axis axes.

and O-OE.

The slide E with limb and alidade can move in two mutually perpendicular directions, and therefore can be installed over any point on the tablet. For ease of reference angles, due to the parallelism of the edges of the beam OD, the slide E can be swapped 180 ° (Fig. 2). Movement of both the slide E, and the beam itself, as well as the index K on the MN can be done directly with the hands, and the exact installation is performed with micrometer screws. The entire device has a clamping fixture for a quick installation on the tablet.

For operation, the device is installed with bevelled edges A and B B exactly on the grid on the tablet and is firmly attached to it with a clamping device. When photographing a tour of a certain area with a starter, aligning the center of the limb with the starting point 1 on the tablet and this point on the ground, orient the device along a compass

and measure the directional angle of this direction. Then, located opposite the initial zero division of the MH line, the center of the microscope is optically aligned with the starting point i, i.e. with the point from which the move is made. The combination is made by moving the slide E and the beam of the SD, first with your hands, and then with micrometer screws. Since the OP line coincides with the sighting plane, to plot the next point 2 on the tablet, it remains only at a fixed scale for the distance measured at a distance of 1-5 to set the K index against the corresponding division on the MH ruler and produce a needle I. To find the next the vertices 5 of the contour of the specified bypass move the device to point 2 and repeat the same work until they reach the last point of the turn.

Thus, according to the inventors, the need to spend a lot of time on office work is avoided.

when it is necessary to perform lengthy computations when constructing a planar traversal by the method of coordinates.

The subject of the patent.

A device for applying points of theodolite passages at directional angles and distances, characterized by the use of two lines A and 5 fastened together by transverse planks parallel to each other with edges sloped inwards, which run on the slide B and the wheel B perpendicular to the lines A and B a bar OD, carrying a slide E, moving along it, to which a protrusion T is fixedly attached to a limb T, having a moving alidade W, rigidly fastened below the protrusion T with a ruler MN with divisions, carrying versus zero microscope And the index K moving along a ruler with a magnifying glass L and a spring needle I dl eacol. and patent A.
