PATENT OFFICE

The invention relates to a device for lifting water by means of Compressed air, which the latter transferred into a container and means in a known manner a three-way valve is controlled. The essence of the invention now consists in that the latter is at a considerable distance from this container and from one Device is switched to which ίο two ropes or only subject to tension Rods connected to a float arranged in the container through the intermediary of a Act lever.

The drawings show, for example, an embodiment of the subject matter of the invention shown:

Fig. Ι is a front view,

Fig. 2 is a side view of the same.

Fig. 3 shows the float seen from below.

Figures 4, 5 and 6 show details.

The device consists of a cast-iron, underwater vessel a, into which the water enters through a piece of pipe b, which is provided with a sieve c and a valve d . A delivery pipe e , which is provided with a check valve f , protrudes into this vessel. The compressed air is passed through the pipe g.
The vessel α also contains a float h (Fig. 3), the lower part of which is provided with holes h ¹ , which prevent any indentation by the compressed air. This float is attached to an axis i , which emerges on both sides of the vessel and is sealed by stuffing boxes. One end of this axis i carries a lever i ¹ , at the ends of which two rods jj ^{l are} articulated, the upper ends of which are connected to a lever z ² attached to the axis m. These two rods are each provided with an adjusting device kk ^l . These parts form one part of the new water lift.

The other part rests on a table or a suitable frame n on which a board 0 carrying two stands ρ ρ 'is screwed. The mutual distance between these two stands is maintained by the cross pieces qq ^l , which are used to accommodate further parts of the device.

On the crosspiece q ¹ sits a three-way valve r switched on in the pipe g , which in a certain position connects a pipe opening into the outside air to the pipe g. By means of this three-way valve you alternately bring the compressed air tank with the water tank and the latter with the outside air in connection.

This cock r is driven by two stops t attached to the crossbar q ¹ , which cross the crossbars u , which, as can be seen from FIGS. 1 and 2, are arranged on a wing ν swinging around the crossbar q .

The swinging of this wing is caused by the rocking back and forth of a pipe section w which, as can be seen in FIG. 1, is bent and provided with stop pieces χ at its two closed ends. The stop pieces χ move the Flüeel ν to the right or to the left, depending on the position taken by the pipe w. That

Tube » ¹ contains a ball y, which rolls back and forth according to its inclination. The tube w is attached to a saddle piece ι sitting on the axis by means of two rods \ \ ^x. A frame 2, the details of which can be seen from FIG. 4, rests on the axis m. This frame rotates simultaneously with the axis m and acts in certain positions with its stops 4, 4 on the tube w . The board 0 has two columns 5, 5, which protrude high enough so that after the lowering of the tube w the ball lies in the angle formed by the central main part of the tube and one of the two legs inclined towards this central part . The new device works as follows:
Assume that the float h is in the position shown in FIG. I by dash-dotted lines. The cock r is then connected to the compressed air tank through pipe g ¹ and to the lower vessel through pipe g. The valve d opens from the outside to the inside and closes automatically under the action of the compressed air, so that the water cannot come out of the pipe b. The water then rises in the delivery pipe e and the water level falls in the vessel α. The float sinks and rotates the shaft i, which by means of the rods jj ^l transmits its movement to the shaft in. The latter moves the frame 2, and one of the stops 4 lifts the hammer n>, which leaves the position indicated in dotted lines. At a certain moment the ball y also rolls in the pipe iv, which suddenly changes into the position indicated by the solid lines. The stop χ strikes against the wing ν and thus turns the plug of the cock r, whereby the container α is connected to the outside air. The valve d is opened by the weight of the water acting from the outside. Then the valve / closes, the container fills with water and the float g rises. There are then movements that are similar to those described above, but take place in the opposite sense. The cock returns to its initial position and the same processes are repeated. Instead of a cock arranged horizontally directly on the cross bar q ¹ , the cross bar can also be provided with a bevel gear which, by means of a corresponding bevel gear 7, ^{transmits the rotational movement communicated to it to a vertical cock r 1} which is attached to a suitable foot of the stand b ¹ . The game of the cock can be regulated by a nut 8. By ^x a small oil reservoir the tap is supplied continuously with oil, so that it operates in an oil bath. This ensures a better seal, the rotary movements take place more easily and water losses become apparent immediately. Pate NT-A ν SPRU c H: Compressed air water lifter with float control, characterized in that the float (h ) arranged in the well inside the vessel (a) , with the help of two tie rods (Jj ¹ J), is placed on a pipe (n>) with a rolling weight outside the well, rocking horizontally to and fro (y) acts in such a way that the three-way cock (r) controlling the compressed air supply, which is connected in a suitable manner to the pipe (w) by lever (vt) , is moved according to the water level in the vessel (a). 1 sheet of drawings.
