SU19800A1 - Adaptation to the bucket-bar to automatically obtain elevations of horizontal distances and elevations of terrain points - Google Patents

Description

The proposed adaptation to the cyprepel is intended to automatically obtain elevations, horizontal distances and elevations, and provides the opportunity to mechanize and speed up the calculations of horizontal extensions of line lengths, elevations: and elevations of terrain points during graduated topographic surveys, reducing this calculation process to a simple readout of elevations or marks and transfer the compass on the tablet horizontal distance line lengths to these points.

In the schematic drawing of FIG. 1 is a side elevational view and FIG. 2 is a section along AB in FIG. one.

The device device is as follows. Go to the cypregel, shown in the drawing by thin lines, in place of a micrometer. On the holding circle 19, a ruler 1 is attached, which has an axis of rotation o and is connected to the kipregel with the free end by means of the lever 5. and the plate 10 screwed to the pipe. The axes of the ruler and pipes are parallel. Perpendicular to the horizontal position of the ruler 1, the ruler 3 is set, sliding along the edge of the stand 6 attached to the ruler by the square 7. The rails 1 and 3 slide the rails 2 and 4 connected by an axis 17, which serve as vernier for counting the divisions along the rulers 1 and 3. The latter are divided by an equal division value. The tube rotating clamp 14 and the micrometer screw to it 12 are transferred higher, and the spring to it is set not spiral, but plate 13. In line 3 a cut is made, along which the line 9 can move with tens of meters inscribed on it. The divisions of the vernier 8 are also moved in the vertical direction with the help of the screw 16 to a distance of 4 mm (divisions of 10 m), and the division plate is fixed. By pressing the screw axis 16 with a cog 15. The ruler 3 divisions are labeled with a ruler 9 from top to bottom, and the vernier 8. divider is also inscribed. Vernier skid 2, and with it the slide 4 with ruler 3, is moved along ruler 1 by means of a slant. krax

the triangular cut-out of the stand 6 draws a scale angle 22, shown by the point, in such a way that the distance of the intersection points of the line 22 with the right edge of the ruler 3 expresses the scale value of the reference along the ruler 1, set in a horizontal position.

The use of the device is as follows. To determine the excess set the pipe, and therefore the ruler 1, horizontally. Dividing the vernier 8 with the screw 16 is set to zero on the nearest division of the ten line 3, then the number 100 line 9 is set against the same division. Sight in normal order. The value of the reference made on the rail is set by the vernier 2 on the ruler 1. In this position, the ruler 3, and with it the vernier, we fix it with the screw 18 and do the elevation count on the vernier 8. If the excess is with a minus sign, then it will be equal to 100 minus the countdown. The horizontal distance of the length of the lines to the point we take with a compass at the points of intersection of the scale angle 22 with the edge of the ruler 3. In the case when the tool stand mark is known, we immediately get the marks of the observation points and the horizontal lengths of the lines to them in the following ways of vernier 8 and line 9 on line 3 set the numerical value of this mark in the horizontal position of the pipe. Then, in normal order, set the numerical value of the reference on the rail on Line 1, put the length of lines on the tablet, taken at an angular scale of 22, and write at the point

her mark, about | Schryu on vernieru 8 line 3 and-t. The work of the cype-preel at two positions of the circle, the lever 5 is taken away, and the pipe is transferred through the zenith. For filming on a different scale, for example, 1: 5000, on a rail should. The sixths are divided into two times larger, and the numbers inscribed on the ticker 9 and on the vernier 8 should indicate numbers two times smaller. Then the accuracy is 0.10 m for a scale of 1: 10,000, it will be for a scale of 1: 5,000 0.05 m. In order not to make corrections for the slope of the rail when working, it is necessary to set it perpendicular to the beam of sight. This is achieved by setting perpendicularly to the plane of the slats of a simple tube, in which the rack and pinion looks at the tool.

The subject of the patent.

The adaptation to the keeper by automatic ruler 1, horizontal horizons and elevations of terrain points, characterized by the use of ruler 1 rotating on the axis O and always remaining parallel to the axis of the pipe, which line 1 is connected to the pipe end by means of lever 5 and carries movable along it, equipped with a vernier, sled 2, pivotally connected to having also a nonius sled 4, walking along ruler 3, which carries an extendable ruler 9 and which with the help of an attached nika 7 slides along the edge supports 6.
