Description

The invention relates to prior art devices for leveling using two fluid containing vessels communicating via a flexible hose.

In the proposed device, using two cylindrical vessels, a snab; envyh, ukreklenymi on the framework of inclined, glass, having a scale of 7 tubes, and the installation of these vessels on stands supported by a prism support and a set screw, to determine the differences in the heights of objects, bringing the liquid level in the tube to zero division, to produce a reading of the height difference only along one of the vessels, in the latter a hollow body is installed, moved with a screw. Water with a small amount of alkali is used as a fluid with a low surface i tension. I

Modifying the device is | that the vessel support is installed instead of a prism on one fixed leg and two set screws.

In FIG. 1 shows a view of one device from the side; FIG. 2 - its top view; FIG. 3 a section along XY in FIG. 1 and FIG. 4 is a side view of a modified instrument.

The device for leveling consists of two almost completely identical instruments (Figs. 1, 2 and 3) connected together by a flexible hose. Each of these devices is a vessel A fitted with an inclined tube B, mounted on a stand C, which is covered from above with wooden frames D and DI with levels E and E. fixed to them. From below the stand C is supported by a support F in the form of a prism fitted in a cover plate H and a set screw G. The vessel is on top covered with a cover I with an opening M for the connection of the vessel A with the outside air. Scion V is a tap with tip S for a flexible hose connecting vessels. The device shown in FIG. 1, 2 and 3, differs from another device (not shown in the drawing), connected to it by a hose and constituting one device for leveling with it, only because the JL screw with a hollow for a fluid by body L. The purpose of this body is to immerse it or move it out of the liquid in vessel A, acting with screw K, to change the level of the liquid in pipe B.

In the production of leveling with the proposed ycTpoicTBOM, first, exactly, in two, located along mutually perpendicular directions, are levels of E & E, connect the two devices connected by a hose in those points whose height difference is determined. With open S flecks S, the water in tubes B will be at the same level. To determine the height difference of these items, it is necessary only to calculate the difference of readings from the meniscus divisions on the tubes B of both instruments. The height difference can be determined by immersing or pushing out the body L in one device from the liquid, until the meniscus in tube B stops at this device at zero division, marking the position of the liquid when the calibrated devices are at the same horizontal level. After that, another instrument, without a hollow body L, is read on the level of the liquid in tube B.

According to the inventor, the most suitable liquid for the device is water, to which a certain amount of alkali should be added to reduce the surface tension.

The modified device differs from the one described only in that the stand C is not mounted on the prism / and one set screw (7, but on the fixed leg O (Fig. 4) and two set screws T, when bivelling)

The subject of the patent

1. A device for leveling by means of two communicating via a flexible hose and containing liquid vessels, characterized by the use of cylindrical vessels A, equipped with fixed on the frames 1) inclined glass tubes D having scales P, which vessels A are mounted on stands C supported by onopot F in as a prism and set screw G (Fig. 1 - 3).

2. In the device described in p. I, the device is used for one of the vessels A, in order to level the liquid in the tube B to zero division, moved with the help of a screw K of the hollow body L (Fig. 3).

3.B described in p. 1, the device is used with a stand C instead of a support F in the form of a prism-fixed leg O and instead of one set screw G- two set screws T (Fig. 4).

4.B characterized in clauses. 1 - 3 The device is used as a liquid with low surface tension, water with some alkali content.
