ALBERT SCHNEIDERS in AACHEN. Spirit level for lifting floating bodies.

Addendum to patent 301975.

Patented in the German Empire on November 9, 1915 "from. Longest duration: October 17, 1928.

The subject of the invention is a special design of the spirit level according to patent 301975. The aim of the innovation is to avoid the chambers of a three-step lock staircase To fill and empty water consumption, in such a way that with the mediation of a swimmer the amount of water in the lower and upper lock chamber the amount of water in a middle one Double chamber holds the balance.

Figures 1, 2 and 3 of the drawing represent shows the arrangement in longitudinal section schematically; Fig. 1 shows the float in half Lifting height, FIG. 2 at its highest, and FIG. 3 at its lowest. FIG. 4 is a schematic top view, of the arrangement.

According to FIGS. 1, 2 and 3, the arrangement consists of the upper single chamber a, the middle double chamber B ' and the lower single chamber c, and also of the three-chamber high container B, in which the three chambers of equal height "', b ', c subdivided floats 5 moved in a lifting height of .zwei chamber heights. At the height of the double chamber B 'there is also the auxiliary chamber b, the size and height of a single lock chamber, or what is the same, a float chamber. The container B is connected to the double lock chamber B ' through the channel k , so that the height between the lower and upper water of the container B' corresponds to the changing height of the water level in the container B (see FIGS. 2 and 3). The double chamber Bf and the container B at the level of this double chamber have the same content of three float chambers. At the highest float level (Fig. 2) is the lowest float chamber c ', at the lowest float level (Fig. 3), the uppermost float chamber β' at the level of the middle double chamber B ₁ ' and the auxiliary chamber b. The float 5 hangs on the ropes, m, which are guided over the wheels r and to compensate for the; The swimmer's own weight are provided with counterweights -p. The float chamber α 'is with the lock chamber a, bf with the auxiliary chamber δ and c' with the lock chamber c in - not shown - connection. In the middle float stand (Fig. 1) all chambers are half filled with water. As FIG. 4 shows, the float S and the auxiliary chamber b can be broken down into any number of parts, only the total content of the individual parts must correspond to the specific amount of water. Deviating from the drawing, the three-step lock staircase can also be built in such a way that the middle double chamber, in terms of the area of the single chamber, is twice as high as this. However, this would have the disadvantage, among other things, that the float would have to be divided into four chambers, of which the two middle chambers are connected to two auxiliary chambers η lying one above the other.

Claims (3)

The operation of the scales is as follows: If the upright float S (Fig. 2) is loaded by a drive weight, for example by raising the water level of the chamber δ, the float sinks to its lowest level (Fig. 3) and takes the amount of water from the lock chambers a and c as well as from the auxiliary chamber δ into its chambers a ', b' and c ', but at the same time fills the' Poppelkammer B 'by displacing a quantity of water from two chambers from the container B. By the rise of the water level In the container B by one chamber height, the immersed swimmer (Fig. 3) displaces the amount of water from three swimmer chambers and, through the inflow of water from the auxiliary chamber b, apart from that from chambers α and c, the balance between float load and float buoyancy in each Given height. The weight difference between the swimmer's load and the swimmer's buoyancy, given by the wall thicknesses of the swimmer, is compensated for by the weights g attached to the ropes m. Another means of compensating for this difference is to add a saline solution to the water in the auxiliary chamber δ and in the float chamber V connected to it. Like. To give a correspondingly higher density. When operating the lock staircase (Fig. 4) there is the possibility of using the rising or falling of the water in all three chambers to raise or lower ships without interruption, since the ships going up and down the mountain are in the middle double chamber can cross. For example, if a ship lowered in chamber α enters chamber B ', it is brought up to the wall on the right, down the valley, while another ship is in this chamber on the right, uphill, in order to enter chamber a to be funneled, at the same time a third ship enters the chamber c after another ship has left this chamber. _ If, after this process and after the gates have been closed, the scales are set in motion and the underwater with the upper water in the individual chambers is changed, the ship moves out of chamber c, evasive to the right, into chamber B ', and then the right downhill to the valley moored ship from B 'to c, at the same time the lock in chamber a, in connection with the upper dewatering, takes place in the same way. For the sake of completeness, it should be mentioned here that the system can also be used in that the auxiliary chamber serves as a lock chamber and the double chamber as an auxiliary chamber. However, this reference has more theoretical than practical value, because such use increases the system and operation considerably, since special water retention is required due to the simultaneous filling of the chambers between the individual lock chambers. ι Patent claims: 1. Water level for lifting floating bodies according to patent 301975, characterized in that a middle double chamber [B ') of a three-stage lock staircase by the water displacement of a float (S) divided into three chambers [a', b ' and c'), its buoyancy is balanced in relation to its load, is filled or emptied when the lowest and uppermost individual chamber [c and a) of the stairs empties by releasing their water to the interconnected float chambers [c ' and a') or are filled by removing water from them, while the middle float chamber (δ ') receives its water content from an auxiliary chamber (δ) or transfers it to it. 2. Compensation of the float load against the float buoyancy according to claim 1, characterized in that in the height of the lowermost float chamber (c ') when the float (S) is high, the container [B) has the content of three float chambers, two thirds of which are in the double chamber [B ') are omitted. 3. Control device for the spirit level according to claim 1, characterized in that that the water in the auxiliary chamber (δ) and in the float chamber (δ ') connected to it' through Increasing its density means the difference between buoyancy and buoyancy compensates for excessive loads.
