The object of the present invention is to pro vide a method and apparatus for pumping fluids 5 whereby the ?uid body being pumped is counter balanced. Inertial movement of the ?uid body is utilized to induce ?ow of an additional volume of ?uid into said body and surges in the ?uid body are employed to assist the movement of a 10 piston or a similar driving element when the pump is operating. Apparatus whereby the method of pumping may be accomplished is shown by way of illus tration in the accompanying drawings, in which: 15 Fig. 1 is a diagrammatic view showing one a rod H]. Two inlet valves I! and I2 are pro vided and similarly two exhaust or discharge valves l3 and M. In actual operation, let it be assumed that movement of the piston 1i in the direction of arrow a will accelerate the body of ?uid in con— duit A in an upward direction and the body of fluid in conduit B in a downward direction, and that said accelerating movements are simulta neous. In that case the piston travel will be the accelerating distance‘ and it also must be as sumed that this distance is equal to the de accelerating distance of the bodies in the conduits A and B. ’ When the piston stops, the acceleration of the form of apparatus whereby the pumping of ?uids bodies A and B will cease but both bodies will may be accomplished. continue to travel due to inertia, but deaaccelera Fig. 2 is a diagrammatic View showing another tion will immediately commence the moment form of apparatus whereby pumping may be movement of the piston ceases.

Referring ‘to the drawings in detail and par ticularly Fig. 1, A indicates a pumping conduit :.0 and B a balancing conduit. The conduits are connected at their lower ends by a cylinder 2 and at their upper ends by a tank or reservoir 3 which serves to maintain the conduits com pletely ?lled with water or other ?uid, and which ‘5 also functions as an over?ow or discharge for the ?uid being pumped. Both conduits and the bodies of ?uid con strained therein are in communication with the cylinder 2 but are divided or separated with 40 relation to each other by a piston A which is driven by an engine generally indicated at C in a manner hereinafter to be described. Conduit A extends as indicated at 5 below the cylinder 2 into a source of supply, such as shown at 6, 4;, the source of supply being the water or other fluid to be pumped or elevated to the tank 3. A check valve 2'' is mounted in the extension 5 and functions in the usual manner; that is, it auto matically opens when suction is applied and conversely closes when subjected to pressure. The engine indicate at C may be driven by any suitable ?uid medium under pressure, such piston for a period of time and through a dis tance required by the force of gravity to bring the bodies at rest. ‘ While both bodies simultaneously or substan upward direction, a partial vacuum is formed at each side of the piston. During this period, the piston is substantially in static equilibrium and while in this state may be readily returned to 35 its starting point, thus completing one’cycle of operation, providing that the accelerating and return travelvoij‘ the piston are each equal to the ole-accelerating distance of the bodies A and B. The accelerating time for the piston being 40 governed arti?cially by the engine C may be as desired but the return movement of the piston must be in phase with body B de-accelerating, and this is governed by the force of gravity. Hence, it is essential that the piston, while re 45 turning, should closely follow body B while de accelerating in an upward direction.‘ The inertial displacement of both de-accele rating bodies is concentrated on the side of the piston indicated at to, and this space will accord ingly be automatically ?lled from the source of It consists of a cylinder 8 in supply indicated at 5 due} to the suction action: produced. Hence, charging, occurs during de which is mounted a piston 9, this piston being ‘connected with the pump piston 4 by means of pumping equal in volume to the combined inertial as air, steam, etc. 30 tially so are de-accelerating and traveling in an acceleration of the bodies and discharging or v2, . 2,065,926 ; displacement of bodies A and B during the accel erating movement of the piston in the direction . ingly open‘ admitting ?uid to the conduit B. The balanced valve 22 remains closed until the piston starts forward in the direction‘of arrow 0. 7 of arrow a. The. travel of the piston’ the direction of arrow a commences from the position shown in ' 7 full lines in Fig. lvrwhere the piston is at rest. The movement is thus slow to commence'with V V but'the speed ‘is graduallyiaccelerated until the piston reaches its maximum speed at the end of the stroke. For this reason, the inlet valve I2 is controlled so that‘the movement of the At that .moment it opens and. accelerating‘movei ment'is again imparted to the bodiesiA and B in the directions'previously described, 'and- when the piston reaches the end of its accelerating : stroke, valve 22 closes and the cycle-of opera tion is repeated.- , -- ' I . 7, ' Inasmuchas the opening and closing of the valve 22 must be‘synchronousyw'ithrthe move» ment of the pi’ston74c, any'suitable means oper- " vpistons 9 and 4 will bean accelerating move ment with 'maximum speed at the end of ‘the ‘able from the engineC may be employed. for’ V _ stroke. .The'return stroke takes place'during .7 alternately energizing the magnets. 23 and‘ 24 so that the valve '22 is opened and closed at the 15 15 the upward de-accelerating movement of the ' > V ‘ r body B and as this movement is rapid; valve proper time periods.

Hence, both conduits are in this instance used as 10. pumping conduits and the resurging movement of the ?uid in the conduits is employed to initi ate and assist in imparting movement to the piston. ' From the foregoing it should be apparent that a method of pumping ?uids has been developed whereby a body of ?uid being pumped or ele vated will ?rst of all, be counterbalanced. Sec ondly, inertial movement of the ?uid in the con duits is utilized to induce the ?ow of an addi 20 tional volume of ?uid into said conduits and re surges in the ?uid bodies are employed to initiate ' ' of one of the bodies to induce an additional volume of ?uid into that body and the resul tant energy of inertial movement of the other 15 body to reverse the direction of initial move ment thereof, and returning the displacement means to its initial position during the inertial movement of the bodies to induce a second addi 20. tional volume of ?uid into the bodies. 6.

In view of the fact that the method is capable 25 of employing a variety of forms of apparatus, diagrammatic illustration has been resorted to being connected at one end with a source or" and while other features have been more or less speci?cally described and illustrated, I wish it understood that various changes may be re 30 sorted to within the scope of the appended claims. Similarly, that the materials and ?nish of the several parts employed may be such as the manufacturer may vdecide, or varying condi tions or uses may demand. 35 Having thus described my invention, what I claim and desire to secure by Letters Patent is: 1.
