To all whom it may concern:

Be it known that I, GEORGE H. SMITH, of New Yori@ in the county of New York and State of New York, haveinvented certain new 'Send useful Improvements in Methods of and Apparatus for Making and Raisin gSalt-Brine from Deep Veins and I do hereby declare that the following is a full, clear, and erect description of the invention, such as will enable others skilled in the'art towhich it-appertains to make and use the same, reference being' had to the accompanying drawings, which Yform apart of this specification;` i My invention relates to a method of and same from deep wells or veins in salt deposits, and is hereinafter described and claimed.

A stratum of solidsalt of from forty to seventy feet in thicknesshas' been discovered in the eonnty of Wyoming, State of New York, at a. depth of one thousand feet and more' yfrom the surface. Owing to the depth and Vprooebie'- cost of drainage, itV is not thought desirable to mine this salt by shafts and drifts. 25 Salt has-been obtained in considerable quan- Y Y`cities by pumping water into wells reaching down `to lthis deposit, and then pumping it ontv ngain'in theA form'of brine. A Water-supply ffrom outside the wells has been found to be l3o*necessary-o1' advantageous, owing to lack of sucient water at this greet depth, eindv also -because the water supplied to .the wells can be kept pure and free from ingredients which might be deleterious to the salt, which might ter were reliedon to ill the wells and dissolve "thesaln 1 I havel invented a method. by which deepwell pumping may be dispeusedwith, all the 4o machinery except the pipes be above ground, and the brine can be obtained more cheaply then has-heretofore been done. My method is now in use ata. well some fourteenhnndred e feet in depthin' the town of Middlebury, New 4 5 York, and gives excellent results. The brine,

after `being forced out of the well, is evaporated,vaud salt formed in the usual manner.

The apparatusby which my method is carried out is illustrated in the accompanying drawings, but is subject to modification within the spirit of the invention.

In the drawings, Figure is e sideelevea tion,`pertly in section, of one form efmy apparatusfin position in a well. Figs. 2 and 3. are modifications, the general principles ofrop- 55 eration being the same. f A represents e deep well, in vvwhich a casing, A', is placed, which extends down below the vfresh-witter veins,- esie usuel in oibwells, at which pointtbe caf-sing is tightly packed with 6o suitable pecking, @to exclude all drainage from the weil, end also to permit the applice- Y tion of pressure from below to expel the brine'. The casing Atmeycr may not'fo'rm one of the tubes or pipes by which the brine is expelled 6 5 from the well. j v v B is a supply-pipe, which may be the casing of the weiber mey bee separate pipe, as shown. Through this pipe water is forced inte the well by eey suit-chie menus, end by. 7o its presscre lforces ont' the water 'which has preceded it inthe weil, enti whichl has become saturated with seit yby contact with the deposit of salt. 'in Fig. the inner pipe is the pressure-pipe, while the casing A' serves es the 7g conduit for tbebrine. v

D is e forcepump,.by which water is forced intothe well, while Eis e stand'pipe counected'with the supplypipe and serves to give a steady pressure; but this stand-pipe may be 8c Y omitted.

In Fig. 3 have shown e wel! in which the casing is dispensed with; but e-paeking n. is used, through which the pressure-pipe B and supply-pipe C pass., In this form einpressnre 85 may be used to force up brine, the water bavin'g been rst introduced into the well to ebsorb the salt.

It is obvious that the pump may be dispensed with vwhere there is e. natura-l heed er 9o pressure of water above the mouth of tbe well, es where` water een be obtained from weterwcrks, es is the cese in Varsaw, New York.

I am were that it -is :not broadly new to 95 raise oil and other liquids from deep wells by heudrsniic or pneumatic pressure; and l do not broadly cla-im such devices.

Wirst I claim is- The method of obtaining brine from salt roo weils, which consists in forcing fresh water into the well under pressure, permitting it to absorb salt by Contact with the undergrour'ldv deposit, and then expelling'the same from the 'well bythe pressure of a column of "water or.

air, alljsubstantially as described.4
