Water depth gauge.

Addendum to patent 190285 from June 6, 1906.

Patented in the German Empire on February 14, 1909. Longest duration: June 5, 1921.

The present invention constitutes an improvement on the patent water depth gauge 190285, in which one or more inlet tubes create a pressure corresponding to the depth The amount of water penetrates into a measuring tube, where it forms a measure of the measured depth.

These known depth gauges had the disadvantage that sometimes a small amount of water escaped from the measuring tube could not be avoided, and this danger occurred when the depth gauge was during soldering gets into a horizontal or downwardly inclined position, which sometimes happens with high-speed steamers.

In order to secure the entry of the water into the measuring tube, however, an undesirable one To prevent the water from flowing out of the measuring tube, the inflow chamber is against the measuring chamber closed by a valve, which is connected to an outwardly guided spindle is provided, which opens the valve for the purpose of emptying the apparatus after the measurement enables.

The accompanying drawing shows some embodiments of the subject matter of the invention.

Fig. Ι illustrates a depth gauge in which the water enters through openings a in the inlet pipe b , and flows from this into the measuring tube c . In the upper part of the inlet pipe b , a ball valve d is arranged, which is equipped with a capillary through-hole β . The valve body d is also provided with a rod f which leads through the lower opening of the inlet pipe b into the open. At the lower end of the rod f , a handle g is rotatably arranged.

When using this apparatus, the handle g is rotated so that its part h rests on the extension i , whereby the valve body is pressed onto the valve seat. When the depth gauge is lowered, the water flows up the inlet pipe, penetrates through the through hole d and flows from here into the measuring pipe in the direction indicated by the arrows. The through hole e is chosen so that the water can penetrate through the same into the measuring tube under the influence of the deep pressure and the compressed air can escape from the measuring tube, whereas no water passes through the capillary tube at the same pressure. Since the risk of overturning only occurs when the instrument has reached the surface of the water while hauling in at high speed, i.e. at a time when the compressed air has long since escaped from the measuring tube, dangerous moments can occur at this time there are no longer any pressure differences, and no water can escape from the measuring tube through the capillary through-hole.

Fig. 2 shows an embodiment of the invention in which a check valve d ^{1 is} arranged in place of the ball valve. The valve body d ¹ also has a capillary through-hole e ¹ .

Here, too, the valve body d ^{1 is} connected to a rod f ¹ , which is equipped with a handle g ¹ at the bottom. The valve body is here under the action of a spring k ¹ , which presses the valve body d ¹ onto the valve seat.

When using this device, the slight spring pressure is overcome by the pressure of the inflowing water, so that the same can flow into the measuring tube unhindered in the manner indicated by the arrows. When the depth gauge is pulled up, the valve body d ¹ is pressed onto its seat by the influence of the spring k , so that no water can escape from the measuring tube. As in the previously described exemplary embodiment, the compressed air escapes through the through hole e ¹ .

Fig. 3 shows an embodiment in which the valve during use of the Depth meter is operated by the pressure of the water from the outside.

The equipped with the through-hole ² e d valve body ² is provided with a rod ^f%.

At the lower free end of the rod f ² , a handle k ^{2 is} arranged which protrudes laterally beyond the depth gauge and is widened in the shape of a tongue at its end at I ^2.

Fig. 4 shows an embodiment in which the handle ² at k m ² is rotatably mounted.

Fig. 5 shows the lever k ^{2 seen} from below.

. When using the embodiment shown in Fig. 3, the valve body d ^{2 is} brought out of its position when the knife is lowered by the pressure of the water on the tongue Z ² , so that the water can penetrate the measuring tube unhindered. When the valve is opened, the action of the water on the tongue / ² actuates the valve in the opposite direction, i.e. it is pressed onto its seat.

In the case of the arrangement shown in FIG. 4, the effect is of course the opposite, see above that the valve must be built accordingly.

In all embodiments is for the escape of the compressed air from the Measuring tube a capillary tube is provided. Instead, of course, a small one can also be used Be switched on valve, which opens under the influence of the internal pressure.

In all embodiments, the measuring tube is emptied after it has been completed Reading by turning the depth gauge horizontally after opening the valve Location brings.

Claims (1)

Patent claim: Depth gauge according to patent 190285, its inflow chamber against the measuring chamber is closed by a valve, characterized in that the valve with a outwardly guided spindle. Like. Is provided, which opens the valve for the purpose of emptying the apparatus after Measurement made possible. For this purpose ι sheet of drawings.
