This invention relates to apparatus for elevating acids and other liquids and more particularly liquids of a corrosive nature where e moving parts such as pump pistons in contact r wit-h the liquid are objectionable and a source of constant trouble. The object of the invention is to provide an apparatus which will 2 act in eifect like a pump, using compressed air, or other gases under pressure, or steam l as the operating medium.

The invention consists broadly in the provision of one or more. containers having inlet and discharge openings and means whereby each container is alternately filled with liquid and supplied with gas under pressure so as to force out the liquid through the discharge openings.

Some of the forms which the invention may take are illustrated in the accompanying drawings in which Fig. 1 shows diagrammatically a vertical section through one embodiment of the invention.

V t Fig, 2 shows a vertical section through the Z 'junction of the discharge pipes in another embodiment of the invention.

In the construction shown in Fig. ltwo cylindrical, or other suitably shaped containers 1 and 2 of lead, ebonite, porcelain or other suitable material are immersed in the liquid to be elevated and are provided with inlet valves so arranged that when pressure is applied to the inside of either container its 3 {valve automatically closes. These valves may consist of rubber balls 3 and 4 resting on seatings 5 and 6 made from the same material as the container, or of glass balls resting on rubber seatings, or any other suitable in combination. Guards 7 and 8 are provided to prevent the balls floating off.

Each container is provided with a discharge pipe 9 and 10, extending from the 2 lowest point of each container upwards through the containers, or outside them, to

thedelivery pipe 11 into which it is dr'efsired to lift the liquid.

Pressure pipes: highest point of each container and are con nected to opposite sides of a two way control valve or cock one positionof which applies pressure to the inside of one container and at the same time connects the inside of the other to the atmosphere and vicervers'a' when w the'control valve is moved tothe other position. c J The body of the control valvejfis formed in two portions 14 and 15 and is in commu-' nication, through the pipes12 and 13, with 12 and 13 are fitted the containers 1 and 2 and,"through a ipe 6o 16, with a s'ourceof compressed :air or other gas under ressure. Arodf17'is slidably mounted within thefbody of thevalve'and' carries aball '18 of rubber or other suitable material which is secured thereon-between a pair of tubularfsleeves 19 and 20 which are provided with longitudinal slots 21' and '22. The rod 17 also carries rubber washers 23 and'2t which are secured by metal washers 25 and 26 andnuts 27 and 28. p 1 'v When, the valve is in the position shown in the figure the rubber ball 18 cuts ofi'the supply of compressed air, delivered through the pipe 16, from the pipe 13 and thus from the container 1. The container 1'1 is however in communication, through the, pipe 13 andl the slots 21, with the atmosphere. The pres sure of the liquid will thus lift theball 3 and the container will fill with liquid.

At the same time the container 2 is 'in comsource of compressed air through the pipes 12 and 16. The slots 22 do not extend to the atmosphere and the bearing of the rod 17 is furthersealed' by the" munication with the rubber washer 24; Any liquid there maybe in the container will thus be rorced up the discharge pipe 10 into the. pipe 11. When all the liquid from the container 2 has been forced through the discharge pipe into the delivery pipe the sudden acceleration of air 9 PATE T] I to a check valve,

turn valve controlling in the system moves the ball valve 18 to the right cutting off the supply of compressed air from the container 2 and opening it to the atmosphere. At the same time the container 1 is shut off from the atmosphere and sup plied with compressed air through the pipe 13, so dischargingthe contents of the container 1 through the pipe 9 while the conta-iner 2 is being filled.

Instead of using two rising pipes both discharge pipes 7 9 and 10 may be connected a vertical section through which is shown, inFigure 2.

The discharge pipes 9 and 10 open into the space within the body 30, and the opening of either of them may? be sealed by the rubber ball 31. The interior of the valve is in com munication with a vertical delivery pipe 11. A guard 32 is provided at the mouth of this pipe to prevent the ball 31 from floating off.

.When the liquid is being discharged from one of the containers through the pipe 9 the ball is forced tothe right,sealing the pipe 10 and-preventing the liquid from flowing back intotheother container. All the liquid is thusforced upthe delivery pipe 11. When all the liquid.has been forced out of. this pipe theair supply control valve operates as above describedv and. liquid is then forced from the other container through the discharge pipe 10; the ball 31 is forced to the left and seals the opening of the pipe 9. All the. liquid is thus. forced. up the pipe 11.

What I claim and desire to secure by Let- Patent is 1 Apparatus for elevating liquids comprising a pairof containers adapted to be immersed. in the liquid to be elevated, an inlet to each of said containers, an automatic nonreturnvalve controlling each of said inlets, dischargepipes leading from each of said containers to a common discharge main, separate pipes for conducting elastic fluid pressure to each of said. containers, a main pipe conducting elastic fluid pressure from a-source of supply to each of. said separate pipes, a valve chest to and from which said main. and separate pipes lead, and having ports towhich said separate pipes arecoua slidable-spindle on which said. valve is fixedly mounted, said spindle passing, longitudinally through said chest and. operating. to close each of said ports alternately, a sleevevalve mounted upon each endofsaidslidablespindle so-as to move together with the ball valve andhaving ports which connect each of the separate pipes to atmosphereby backpressure when said ball valve operates to shut ofl'the supply 'of elastic .pressureto such pipe.

2.1 Apparatus for elevating liquids comprising a pair of containers adapted-to be immersed in theliquid'to be elevated and each having an inlet, an automatic non-reeach of said inlets, a

common discharge main, discharge pipes leading from each of said containers to said common discharge main, a main pipe for conducting elastic fluid pressure from a source of supply to each of said separate pipes, and an oscillating valve member between said main and separate pipes and directly exposed to the flow of elastic fluid, said valve member operating to connect each of said separate pipes alternately to the atmosphere and the main pipe and being actuated solely by the acceleration of the elastic fluid flowing past it. In witness whereof I aflix my signature.
