TURBINE PUMPING MECHANISM.

' `srscxFIcArIolv forming part of Letters Patent No. 656,465, dated August 2l, 1900.

pplication filed Api-ll 30, 1900. Serial No. 14,848. i (No model.)

-l'o1 `all 'who/n it nuty conoci-1u y Be it known that I, FRANZ MARBURG, Jr.,

. a citizen of the United States, residing in the boroughof Manhattan, in the city,

county, andStaL-e otNew `York, have invented cer taiunew and useful Improvements in Turbine Pumping Mechanisms, of which the following` is-a specification. i

This invention relates to the class of .tur bine` mechanisms, such as force-pumps, for elevating a column of water. A typical mechanism of this character embodied in an axialfilow `turbine is illustrated in the United States Patent No. 647,856, granted to me ,foravoiding end. thrust or, in other words,

1the eduction side of April 17, 1900, and reference may be had t0 thisfpatent ter a fuller understanding of the construction and arrangement of the turbines andihei'r iixed guides, th'emeans employed on the turbine-shaft, and the requirement It may be said here, however, that where a pump of Vthis character is required to lift waterorother :Huid against a head or pressure, where the pressure is greater at the cduction side than at the induction sideof the pump, it is necessary at starting` to set up a current or flow through the apparatus before a head or pressure at the pump can be over-` come, `and in order before-mentioned patent is shown .an automatically-operated relief-valve which opens the eduction side of the pump in a manner sito avoid material pressure or resistance to the flow until acurrent with sulcient velocity shall have been established, after which Y the -valve gradually closes.

In the present construction in lieu of re- `-`lievingthe pressure at the eduction side of the pump the .object is tc counterbalance or overcom'ethisfpressure by the admission inil tiailyof duid under pressureat the induction side of tl r pump.

Several embodiments of the invention are illustrated in the-accompanying drawings,

wherein-'- Figure -1 is a sectional elevation of one form i ofrthe pumpi lshowing a pressure-tank and A manual control.

sfo

Fig, 2 is a similar view, Ibut showing automatic control.v Fig;'3 is a similar view showing a construction with autouraine'V control where the counter-pressure for relief at starting. -l

to accomplish this in my on the induction side is obtained from a duid under a head or 'pressure from any source. Fig. 4-is a similar View showing counter-pres sure under manual control similar to Fig. 3 and in addition a relief-valve on the eduction side of the pump. Fig. 5 shows a construction where the counter-pressure is supplied from a tank which is itself supplied by the pump.

For the ,reasons already sta-ted it has not been deemed necessary to show the specific construction ofthe interior of the pump.

My present invention is not specifically limit-ed to any particular construction of the in my before-mentioned patent will serve.

In the construction herein shown l is lau outer casing into which the liquid flows or is drawn through the induction-inlet 2. From #the annular chamber 3 in the casing the liquid iiows into the ends of an'inner cylinder 4, fixed inthe casing 1 and containing the turbines 5on their shaft 6. Preferably there will be two sets of these turbines, each set having iixed guides, all as clearly shown in my said foi'mer patent. The liquid taken in -at the ends of the cylinder 4 will be discharged ata central eduction-outlet 7.

So far as described above the pump has no features of novelty over that in the said patent.

. Referring now to Fig. l, 8 is a closed pressure-tank, and 9 is a branch pipe connecting the eductlon sideof the pump with said tank. A pipe 10 cpnnects the tank 8 with the in the turbine suicient to overcome the pressure at the discharge,`

and when this current be gradually closed.y Ifliave shownjclrikvalves 12 in thlseverai'pipes; rbut theseare,

shall have been .established the' valve 11 will' turbine mechanism and that fully illustrated duction side of the pump, and iu it is a manul eduction side of the pump and permits the" V4astaa.blish|11ent of a currentaxially through :ca

well-known `featuresand form no part of my invention. A check-valve may beplaced in any one of the pipes of the apparatus or pump where it is needed.

`Fig. 2 shows the same construction as that illustrated in Fig. l, except that the valve 1l is replaced by au automatically-operating valve 13, which is normally'open and closes automatically when a current shall have been ro established through the pump. This valve is in the form of a hollowpiston mounted to move up and down in a casing 14 fand pro-` vided with oppositely-arranged contracted ports 15, through which the liquid from the '-15 tank 8 flows to the induction side of lthe pump. Thevalve 13 has lugs 16, these lugs being supp'orted,"when` the valve is open, on ashou'lder in the casing. The casing, above the valve is connected with the induction zo iside of the pump by a pipe 17,"having in ita valve 18, whereby' a regulabley `resistance. to

y lclosing of the valve is providedv and the latter is caused to close gradually. When a cur- ."r'ent is established through the pump, the z5' pressure in thechamber 3wil1` be reduced,

and owingto the contracted character vof the v ports 'in' the valve 13 the pressure under the latter will be greater than that above it, so that it will rise and close the ports l5, thus 3o cutting oi the'iio'w of liquid from the pressure-tank to the induction side of the pump. Eig. 3 illustrates a construction which, zis

- the same as that seen in Fig. 2, except that in theconstruction of Fig. 3 the' pressure- 3,5 tank 8 and vthe supplying branch pipe 9 are' -omitted andthe pipe 10 is "to be supplied "from any source where there is a head-for example, from astreet-ma'in' if the pressure .therein is suitedto thepurpose. "lhe'auto- 4o `matic valve device illustrated in thisview is the same as thatshown in Fig. 2.k

' The construction shown inFig. llis the same I as that seenin Fig. 3, except that the pipe .10?

fromthe main or othersource of liquidunder pressure and whichcorresponds to the pipe Y 10 of Figs. l, 2, and' 3 is rprovided-with a .manually-operatable valve'll, like that 'of Fig. l, and there" is a relief-valve 19 at the eductionfside of the pump to assistinfrelie'v- 5o ing the pressure. As avariant from the construction illustrated' in my former patent thefpipe 17 from the tcp of the valve-casing .leads to an "elevated part cfa Waste-outlet 'pipe QOandnotto the induction side 'of 'the pump. "l The' object of this connection is toV `insure themaintcnance of liquid above "the valve in the casing. The operation of such a relief-valve is'fully explained in my former A.patent and Ineed not berepeated here.

yiuga tank under .pressure-#as those used toloperate elevators', for example-411e' construction shownin Fig. f5. may be employed; lnthisfigure', 2l is the tank, which is `connected directlyvvith th'el ednction-pipe'Z 'ofl the pump. The pipe l0 connects this 'tank with-the induction sideot i ihepump, so that the pressure within the pump is balanced, as'the automatic valve controlling the pipe 1D will be normally open. 1

This valve will graduali close, however,

when a current shall ha been established through the pump. Obviously `this form of the apparatus might have a manually-operatable valve 1l yinlieu of the automatic valve, ifdesircd. 1

The pump illustrated herein and that shown in my former patent are axial-liowturbines; but the same requirements exist in radial-dow turbines as well-that is to say, a current must .be established through the turbine before pressure can be overcome at the eduction Y side of the apparatus.

mechanisms and valso to anyI force-pump driven `by an electric motor or gus-engine where it 1s. necessary for the motor to get'upA speed before the load is thrown on.

My improvements'tre applicable to both of these classes of turbine.

It will be understood that by back pressure at-the eduction side of the pump 3 is meant a considerable or material back pressure. Tlie pump would at starting overcome a slight pressure due to friction in the passages and the like.v y f `Having thus described my invention, I claim--- f 1. A pump having controllable. means for admitting a iiuid under pressure'or head to its 'induction side to wholly or partially counterbala ce the normalexcess of back pressure at the e uction side thereof.
