HYDRAULIC PUMP.

Application filed February 12, 1916.

To all whom it may concern:

Be it known that I, JosErH BITTER, a. subject of the King of Italy, and a resident of Orizaba, in the State of Vera Cruz, Mexico, have invented a new and Improved Hydraulic Pump, of which the following is a full, clear, and exact description.

My invention relates to means for automatically raising water by hydrostatic columns to a height greater or equal to the hydrostatic column used for raising the water. n

An object of the invention is to provide a simple, inexpensive and efficient valveless hydraulic pump without any reciprocating parts.

Another object of the invention is to provide an hydrostatic pump wherein the liquid raised and the raising liquid may come from independent sources.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in both views.

Figure 1 is an elevation of my apparatus, partly in section to show the details of construction, the figure illustrating the apparatus while raising water and Fig. 2 is a similar view illustrating the apparatus while accumulating water to be raised.

Referring to the drawings, 3 is the distributing tank connected by a conduit 4 to a suitable source of water. An hermetically closed tank 5, positioned at alower level than the distributing tank 3, is connected therewith by a conduit or pipe 6, the diameter of which is larger than that of the conduit &. The pipe 6 extends from substantially the top of the distributing tank 3 to substantially the bottom of tank 5, which is the compressor tank. From substantially the bottom of the compressor tank 5 risesa siphon 7, the bend 8 of the siphon being at a slightly lower level than the mouth of the pipe 6 within the distributing tank 3, said siphon 7 discharging into the atmosphere.

An hermetically closed tank 9 is connected to the discharge tank 3 by a U-shaped tube 10 extending from the bottom of the distributing tank to the top of tank 9, which Specification of Letters Patent.

is the charge-receiving tank. The said tank 9 is placed a little lower than the level reached by the water in the distributing tank 3, so that the water flows from the one into the other by gravity. The charge-re ceiving tank 9 is connected to the compressor tank 5 by a conduit 11 extending through the tops of the tanks 5 and 9. Through this conduit the compression exerted in tank 5 is transmitted to tank 9. The discharge conduit 12 leads from the bottom of the charge-receiving tank 9 to the top of an open tank 13, which is a receiving tank and which is located at any desired height above the tank 9. The discharge pipe .is preferablyin the shape of a spiral. The capacity of tank 9 is less than the liquid holding of a section of the spiral 12, which section is shorter along the vertical than the shorter branch of siphon 7, that is, shorter than C'H. The capacity of tank 5must more than exceed the capacity of tank 9 as many times as the height of tank 13, measuring from the tank 9, exceeds the height CH. For example, if CH is equal to three feet and tank 13 is thirty feet above tank 9, the capacity of tank 5 must be ten times the capacity of tank 9 plus an excess.

The operation is as follows: T/Vater enters constantly into the distributing tank 3 through pipe 4:, descends through pipe 10 and fills tank 9 up to the upper end of pipe 11, the pipe 11 being slidably mounted in the tops of the tanks 5 and 9. By moving the end of pipe 11 more or less into tank 9 the receiving capacity of same can be modified. Then the Water in tank 3 reaches the brim of tube 6 it overflows into tank 5, where it compresses the air and rises gradually into siphon 7 The compression is transmitted through pipe 11 to tank 9. The flow of water through pipe 10 is thus held back, and the contents of tank 9 are forced into the spiral 12. As the water keepsrising in the pipe 6 and siphon 7 all the liquid of tank 9 will soon be inclosed in a given section of the spiral 12 shorter than 0-H on the siphon; and as the liquid column so formed is statically lighter than the column of water necessary to reach the overflowing point H in the siphon it gives way constantly before the pressure exerted in tank 5 and is rapidly pushed out and discharged rapidly into tank 13. The same pressure is constantly exerted through pipe 10 as well, but will never repel the water farther than the bend therein for the height from the bend to tank 3 is greater than CH.

When all the water from tank 9 has been exhausted through the end of spiral 12 the liquid in tank 5 should have risen nearly to come in touch with the lower end of pipe 11. It may be here remarked that by adjusting the lower end of pipe 11 the capacity of tank 5 can be modified as required to work the apparatus with the smallest possible waste of water. It will be seen that as soon as the water comes in touch with pipe 11 Within the tank 5 the liquid rises simultaneously in pipes 6 and 11 and in siphon 7, but the shorter arm of the siphon 7 being the shorter of the three, the liquid passes the point H in the siphon and starts the siphon, and the contents of tank 5 are discharged through the longer arm of the siphon. In this phase of the operation the tank 5 act as an open tank, admitting air through pipe 6. For this purpose pipe 6 is made larger than would be required to carry down the water entering tank 3 through pipe 4. The longer arm of the siphon exceeds the shorter by A-B, and it is materially greater than AC, the height of water in the tank 5. Due to the fact that a certain suction is exerted and the air is drawn into tank 5 through the conduit 6 which keeps up the flow of liquid through the siphon, and the flow is all the more rapid the greater the length AB as compared with AC. In this phase the tank 5 is fed constantly by the small quantity of water delivered by pipe 4: and drained rapidly at given intervals by the large siphon 7 While tank 5 is being emptied, the pressure keeping back the liquid in pipe. 10 is released and water from tank 3 can enter tank 9 (see Fig. 2). In due time siphon 7 runs dry. Water again fills tank 5, whence pressure is again transmitted to tank 9 and the pumping cycle is repeated. Tank 9 can be fed from a different source than tank 3, thus permitting the raising of water or liquid of a different character to any height by means of any kind of water, and this even if the two sources are located far apart, by giving the required length to theair pipe 11.

It will be noticed that my apparatus is devoid of any movable part. Its function is automatic and depends only on the supply of water. Attention is called to the fact that the conduit 6 forms an overflow from the distributing tank and that the siphon is adapted to discharge the contents of the compressor tank at a rate exceeding the supply of the pipe 4 to the distributing tank whereby air enters into the compressor tank, and the cycle of the apparatus is then repeated.

While I have described the principle of operation, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatus shown is merely illustrative and that such changes may be made as are within the scope of the appended claims.
