SU62762A1 - Method and device for the summary of adjacent sheets of tablets - Google Patents

Description

In conventional office topographic practice, a summary (link) of adjacent sheets of tablets is produced by visual means. On a narrow strip of stencil about 5 cm wide, they draw a frame of the collapsible tablet, and on the other side of the frame copy the situation. After that, on the summary-stencil, the final position of the contours and contour lines is established both at the points of intersection of the frame and near it. Then the stencil is bent along the frame line and the achieved consistency is transferred onto the reducible sheets of the plates.

To speed up this operation, the summary offers an optical way of combining across the frame of adjacent sheets of tablets. For this purpose, monocular binoculars are used, mounted on a ruler that is fixed on the table above the line of intersection of retractable tablets.

With this method, the need for applying the waxing is completely eliminated and the work is reduced to continuing to draw a situation on the relief in the frame of two aligned plates visible in the field of view of binoculars.

FIG. 1 shows a ruler, a perspective view; in fig. 2 is a diagram of the binoculars used in the device; in fig. 3 - double frame of two tablets; in fig. 4 - a detail of the device; in fig. 5 - crossbar ruler; in fig. 6 is a cross section of a ruler.

The device consists of two parts: a ruler /, mounted motionless over the plates, and monocular binoculars, mounted on a movable crossbar of this ruler.

The main ruler / (figs. 1, 5, 6) serves to place all the details of the device and has a trough-shaped section. At the ends of the ruler, nests a and a are made, which serve for the placement of calibration needles. The ends of the ruler are terminated with tires b and b with cutting, with which the ruler is fixed in racks.

Inside the main ruler there are: a narrow ruler 2 and a ruler 3, all carrying a transverse scale. The main ruler 1 carries two-meter divisions, and the powerful extension of the auxiliary ruler 2 is a centimeter scale. The movement of the ruler 2 is produced by turning the screw 4, fixed at the end of the ruler.

No. 62762- 2 On the ruler / is installed with the possibility of dislocation of non-arrays 5. The ends of non-arrays can be extended with the similarity of the pinnewn's legs carried at the ends of the socket 6 to place the objects in the binoculars in which there is a pin 7.

The extension of the ends of the non-link is fi xed by pressure n screws 8. At point 5, there is also an insert bar 9 with a beveled outer edge from which the ruler 3 is measured. On the ruler / there is a collar 10 connected to the cross bar // with a screw thread. When the clamp is attached to the ruler / pressure screw and when the rod is turned //, the crossbar 5 moves along the ruler 5. The clamp can also be connected with the swivel bracket 12 and the ruler 5.

A monocular biocle (Fig. 2) consists of a tube 13, carrying an eyepiece 14 and lenses 15. The lenses are mounted on retractable arms 16. To direct the light beams from the lens to the oculus, it serves as a beam. The tube carrying the eye can not be reversed for focusing on the image.

In order to secure the entire device over the plates, the stands / 7 are installed (figure 4). The rack with the pomoid screw 18 is fixed on the table 19. Tires of the bb rulers are inserted into the sockets of the 20 racks. The nuts are screwed onto the loose ends of the plugs.

The proposed yeTpoiicTBO, the nominal purpose of which is to produce adjacent lines of tablets, can be used for other works: measuring the lengths of the frame, the breakdown of the kilometer grid, the grid coordinate grid, and so on.

When a summary of adjacent tablets after the x etapki uterroitva to its original position, the edge of the slider .9 results in a zero line. Then, the new plates put the device node in a row, so that the corners of the frames coincide with the spiers. Having fastened the plates, the cross-bar is moved along the ruler “away from itself and the upper corners of the frames are combined. Then, consider the image of the part of the reducible frame in the eye of the binoculars, with pen mark the contours and the relief in the frame. In the event that there is a discrepancy in the survey data, the looping is done at the middle position indicated by the spiers. If it is necessary to reduce a difficult relief, for example along a slope, or small contours, then the cross member is moved with a clamp screw.

If the icons are reduced from the rafter, then the shnl mn can be easily punctured or marked with a pencil, the cross-pieces are slightly shifted and traced with a pin-stick or pencil. Thus, with the very sharp movement of the cross-bar and at the same time, with the help of a pen-grafting tool, the whole frame is attached.

Claims (2)

1. The method of summarizing the plates of the tablets, etc., about the same to the fact that for the optical alignment of the edges of the adjacent sheets of tablets use monocular binoculars. 2. A device for carrying out the method according to claim 1, wherein the lenses of the binoculars are located at the retractable ends of the ionerin mounted on the ruler, with the possibility of not displacing them along the latter.
