Description

The proposed device is intended for interpolation in order to replace painstaking and time-consuming calculations, in which frequent errors are possible, by mechanical actions, which make it possible to speed up and simplify the work on interpolation.

Thus, in particular, the device can be used to plot the plan in the horizons, to find individual points on the available horizons of the points, to determine the intermediate values of a function, etc.

In FIG. 1 shows the device proposed, FIG. 2 is a view from the back of the device, FIG. 3- | section along AB in FIG. 1, fig. 4 shows a section along BG in FIG. 1, fig. 5 and 6 - parts of the device.

This device consists of two mutually perpendicular and located at the edges of the division lines Dk L, of which the line L is equipped with two sliders M, M with pointers H and U, fastened, with trapezoidal, slanted mutually perpendicular lines, transparent, for example, a celluloid plate Y, and bears hinged on it, reinforced in zero divisions along the upper rope of its Oi and Oi ruler. The D line is fitted on the back side with a slide W, with which it is attached to the middle of the line L, then to the front the parties have m divisions and bearing indexes I and K with the engine E and, finally, the stroke of the engine zdim along it 3. The ends of the lines Oi and Oz are clamped, each between the three plates C, PI, / 7 and Ca, Pi, P-i, allowing , due to the large hole in the middle plate (Fig. 6), when rotating these rulers, see the centers of their rotation.

In order for the celluloid plate U, U to move freely under the ruler D, the latter is raised above the ruler L by the thickness of the plate and has pads T, T.

On the ruler D, two shkalas are applied along the edges in millimeters with digits 10 mm from O to 10, and in the middle on the left the same scale with digits from O to 10 and to the right from 10 to 20.

The E engine has millimeter scales at the edges with numbers from O to 10. On the topline L, on the upper edge, there are two buttons with increasing numbers from the edges to the middle, and at the bottom edge - ordinary | 1 scale millimeter scale.

When putting contours on the plan, apply a ruler L to two points with leveling marks so that the point with the lower mark covers the center of the hinged ruler O or Och, and the other point touches the edge of the ruler L. Then, if the last digit of the mark is greater than the last digit

the lower mark (for example, 688.5 and 683.7; iS 3), then the subtraction is performed on the left scales of the D to E rulers. Then the lower pointer K shows the difference in marks.

If the larger mark has the last digit smaller (for example, 691.4 and 688.5; 1 8), then use the right scales D to E and on the scale D set the last digit of the mark, increased by 10, i.e. 11.4 and combine with her figure 8.5 on the ruler E. Then the upper pointer I will give the difference of marks.

Having established in this or that case the indicator K or I the difference of marks, CONDUCT the indices H or H-2 to the second point. The left part of the device in the case when the left point mark is less than the right and the right part of the device - when the left point has a mark greater than the right.

After the M /// 2 AND indicators are set, the Utac plate is moved so that either the horizontal line matches the I or K indicator. On the intersection point of this line with the vertical line passing through the // // 1 / or pointer C / set the line Oi / or Oa /, for example, as shown by the dotted line.

Now determine the first horizontal. If, for example, the smaller mark is 688.5, then the first large horizontal 689 is 0.5 at a distance from it (when holding them through 0.5 meters). Set the pointer K to 0.5 and find the points of intersection of the horizontal lines of the plate U, U with the ruler Oil or Oj /. They took them using the vertical lines of the same plate to the line L, get the points through which the horizontal must pass.

The instrument, shown in the drawing, is constructed for contour lines through 0.5 meters. If others are needed

intervals: (1 or 2 meters), then the points are drifted through one or three divisions.

Using the device, you can solve the inverse problem, i.e. according to the plan in horizontals, determine the mark of any point. To do this, you need to attach the ruler L to the point whose mark you want to define a tick, so that the center of rotation of the ruler Oil or Oz / lies on the nearest smaller horizontal, and any division of the scale L on the adjacent horizontal. Then, the indicator K is placed on the value of the contour lines change (for example, 0.5), the horizontal line of the U, U plate is brought to it and at the intersection with the vertical line passing through the intended division of the scale L, set the line Oi / or Oz /. Then he took down the point, the mark of which is determined by the vertical lines, to the ruler Oj and Oz.a from it, using horizontal lines — to the scale on the ruler D, read the value that must be added to the horizontal mark to get the desired mark of the point .
