IMPROVEMENT IN TUBE-WELLS."

Be it known that I, WILLIAM` II. WHITE, of Lynn, in the county of Essex, and State of Massachusetts, have invented a new and useful Improvement in Tubing for Wells and I do hereby declarethe' following to be av full, clear, and exact description thereof, suilicient to enable others skilled in the 'art to which the invention nppertains to uiiderstand and use the same, referencelbeing'hndto the accompanying drawings, which are made a part of this specification, and in which* Figures 1 and 2 are side elevations of the lower sectionof a well=tube and its appurtenances, illustra-ting my invention.

Figure 3 is a central longitudinal section of the same.

upon an enlarged scale.

Figure 5 is a detached view of oneV of the strainersl hereinafter referred to. Figure 6`is a. front view ot' one ofthe ordinary strainers.v Similar letters of reference indicate corresponding parts in the several figures. The water-inlet openings in the lower section of the tubing of a tubular or driven well are liable to be clicked Figure 4 is a. longitudinal section in a plane vat right angles tothe plane of sectionof g. 3,' and drawn up with sand, mud, and various'other substances, in the act of lowering or driving said tube to the depth where i water exists; and this choking occurs whether the inlets consist Aof an aggregatiou'of smallperforated-holes, or of a large hole guarded by Aa wire-gauze strainer. i.

KThe object of my invention is to prevent the choking up of the inlets, and insure the freeentrance ofwater into the tube, when the latter has-been driven or lowered t'o the point wherewater exists.

I prefer to attach to the lower section A. of the w`ell-tub,e, a. point or drill, B, constructed and applied in a manner to be hereinafter described. This point makes the tube a self-sinking one, yet the invention is equally applica-ble to tubes for which a hole is made by a separate instrument and separate operation, wheth'e'i" the bottom of the tube A-bc closedby the permanentattachmcnt of the drill B, or otherwise. I provide the sides of said tube with openings a' a, into which are fitted theinduction-tubes b. These tub'es, (sce'iig. 5,) are pro.- rded with peripheral pcrforations, and are adapted to slide in and out ot' the wcllftubc A. In figs. l and 2, said tubes If are shown as retracted within the welltube A, in which position the solid dsksb, which-close the outer. ends oi' said tubes b, occupy countersunk encounter-drilled recesses around the openings a cz, awd are thus caused to be flush with the outer surface of the well-tubeV A. The tubes Z are h'cld within the well-tube A, as infigs. I' and 2,' by the springs c, to which they are attached in any suitable uianner. After the Vtube A has been sunk to the desired depth, the tubes Za are all. protruded or'madc to project, as shown in ig.' 3, by depressing a rod, O,within the willi-tube, said rod being either hollow and perforated peripllcrically, or cross-shaped in transverse'scction, or otherwise constructed so as to admit of the upward passage of thc water in tube A, after said rod-has been fully depressed. I I

From the above it will be seen that the water-inlet perforations in the tubular indugtionsb arc electually protected against choking while the well-tubo Ais in process of sinking, and Awhen the`lntter has reached the point where the water exists, the projection of the tubes bby the introduction and dcpressionot` rod C, insures the free entrance of water into the well-tube. i I

The tube A is provided with perforations c e, in one or more places, or with any constantly open strainer or straincrs, to indicate when water is reached by admitting the same to-the well-tube. V

The sections of tubing are 4connected together by the couplings D.

The point or drill B, I make in a. solid and substantial manner, with its upper part, :it least, of the full diameter of the coupling E above it, "so that said coupling as well as those higher up, D, and also the'wliole of the tube between,` shall bc, as far as possible, relieved fromthe pressureand friction ofthe earth through which they pass. I

|Ihe general form of the point or drill B is that` of a wedge, with a circular extremity, and after attening it, I twist it along its length after ,the manner of abit or auger, but only to the extent of about one-quarter n*substetntialiy as described.

of o revolution, so thatthe greatest strength for sustaining longitudinal pressure shall be` preserved, eonssten Withn sucient twist to produce nideeided rotary movement of th'e tnbe, as it descends into the earth.

'By this rotation of the tube it is intended to assist the descent of the tube in soils through which it'ean be pressed or driven, 'ond it is also intended, in soils of ahnrder character, *that the t'ube thus pointed may be turned about and madeto act as its own drill, Without being lifted from its place. v

Having thus described my invention, what I claim as new herein, and desire t-o secure by Letters Patent, is- The combination, with.a. WeilK-tube, A, of the movable .strainers or inductionltubes, appiiednnd operating To the above I haveA signed my name, this 25th day of March, 1868.A l WM. H. WHITE Witnesses:
