- My invention relatesto moving or transport ng liquids and especially to extracting or pumping li uids from deep wells or other source of supp y in a new manner, its main similarly the limits usual with pumps for other liquids donot persist. In order that my present invention may be clearly understood'and easily carried into practice, a. preferred embodiment thereof has been shown in the appended diagrammatic drawings where-' in Figure lis a vertical section of a well and apparatus and Fig. 2 is a diagram of the curve of the pressure wave to which reference will be made hereinafter.

In the embodiment shown the device consists of a pipe A through which the liquid is withdrawn. The pipe reaches to the bottom of the well, or to the liquid level therein, and

- is of a suitable length as will be explained. At

the bottom of the pipe is a check or,retention valve V. The upper end ofthe pipe A is'connected at or about the ground level with a pump or compressor 0 preferably making rapid reciprocations with a short stroke. The

compressor is a valveless pump and is rovided with an outlet controlled b an ad ustable cock or the like R, through WhlCh the pumped liquid may pass from the system. The cock may beopened at the beginning of the opera- --tion but may be adjusted to a desirable point during operation. I v 7 Before starting the operation of the compressorcare must be taken to completely fill the pipe A and the cylinder of the compressor with liquid, carefully excluding substantially all free air and being sure that the piston of the compressor is in the outermost position.

- It is well known that energy may be conup a wave motion therein. Thewaves so set up are comparable to sound waves or waves of 681,068,, and in Argentina December-3, 102s.

electric energy. In order to set up suchwaves 1t 1s necessary to cause alternate areas of high and low pressure in the .medium and this may be effected by any suitable known means. 7 I find" it convenient to use for this purpose a reciprocating piston. The piston of the compressor C when rapidly reciprocated sets up waves in theliquid in the pipe A by alternately compressing the liquidili the p1pe and releasing the pressure especially when the piston has a short stroke. These waves have a length L equal to g in which nis the number of strokes per second oft he-piston of the compressor G and 'v is the speed'of the wave per second. When operating in water the speed of the wave may be substantially,-

the speed of sound in the water under the 0perating conditions.

As may be seen from the diagam in Fig. 2 the wave form includes bulges 13 ,13

which are associated with corresponding I nodes N N N 'When the closed end of the pipe is at a distance from the reciprocating piston equal to any number of half waves, that is at O 0 O or when the pipe is cut off at a distance equal to any odd number of quarter waves, that is at N N N a stationary wave may be set up in the pipe. For the purpose of the present invention'it ispreferred to arrange the valve V at the end of the pipe and adjust the apparatus in such a way that the valve will be at an odd quarter wave length such as N or N .etc., but the purpose can be accomplished, possibly less efficiently, by other adjustments.

variation in flow of the liquid. -By the pre-. ferred arrangement of placing, the valve V at the point N or N etc. the liquid may enter continuously. The valve V tends to remain always open but it may open and close from A time to time during the operation. On the I ducted through a column of llqllld by setting other hand the liquid will flow more or less intermittently from the cock B when it is ad-' pressure in the apparatus may be regulated by choosing an appropriate diameter of pipe and by employing a piston of theproper cross-section, stroke and speed. If required or thought desirable or necessary there may be installed a liquid filled bottle or chamber to act as a capacity or condenser in the manner well known in connection with the trans. mission of energy by means of waves traveling in'liquids.

I have found that one specific appropriate apparatus which will illustrate in a concrete way the present invention may consist ofa fluid pi e having an internal diameter of one inch. uch a pipe placed in a well havin'g water at a depth of meters may have arranged at its lower end a valve opening millimeters in diameter seated 111 which 1s aball of approximately 38 millimeters in diameter and held in place by the usual cage which may be adjusted so that the ball can rise from its seat about 20 millimeters.

On the surface of the earth the pipe may be led into 'the cylinder of a compressor of mlllimeter diameter in which is a piston having a stroke of about 36 millimeters. The piston may be refciprocated at a speed of about 360 revolutions per minute by an electric motor. Leading out from the cylinder of the compressor may be a pipe of one half inch internal diameter in which is placedan adjustable cock or valve; The cock will not be closed but is a used merely for adjusting the out flow. The

ing the electric motor the ball valve will lift from its seat and may remain open through out the operation when the cock is properly adjusted, but it may vibrate from its seat opening and closing during the operation. Water will begin to flow from the outlet and by an appropriate adjustment of the cock a continuous operation may be efi'ected and an output of 1,000 liters per hour procured.

While the fundamental theory on which the operation is based may be somewhat in doubt, I believe that the rapid reciprocation of the piston working upon the water .in the apparatus produces a series of periodic pressure variations with periodic changes of pressure and volume throughout the liquid column due to the elasticity and. compressibility of the liquid. .The energy waves so set up travel to the valve V at which point they may be reflected and the transmitted energy is suificient to open the valve V and lift the column of liquid at the same time drawing in prossor the latter being at or about the ground level. The valve at the lower end of the pipe will be subject to substantially no wear it the valve is substantially always in its open position during the operation of the compressor. On starting this valve is closed and great care must be taken when filling the pipe and cylinder with liquid to see that substantially no free air remains in the system.

The piston may work either with the cylinder horizontal or with the cylinder vertical or inclined. The pipe through which the liquid flows may be either horizontal or vertical or inclined and it may be curved or straight. All of these arrangements may be referred to as pumps and I use the term pumping as including moving, transporting or conveying in vertical or horizontal or inclined di rection.

The term liquids is used to include not only simple liquids but also mixtures of liquids and such mixtures of liquids with gases or solids as are capable of being transported through pipes or pumped.

It is obvious that the device has been shown only as a preferred embodiment and that any other may be used for the same purpose. Apparatus for carrying out the invention may be constructed from mechanisms or 'devices already known and used for other purposes and the invention is not confined to any specific form of valves or compressors or means of operating them.
