HIRAM ARNOLD,1OF GOWANDA, NEW YORK. Letters Patent No. 73,6%, dated January 28, 1868.

IMPROVEMENT IN WELL-TUBES.

T ALL WHOM IT MAY CONCERN:

Be it known that I, HIRAM ARNOLD, of-Gowanda, in the county of Cattaraugus, and State of New York, have linvented a certain new and useful Improvement in ITube-Wells; and I do hereby declare that the'iollowing is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in wl1iclr I i l Figure 1 is a sectional view'oiI my improvement in the act of being driven into the earth.

Figure 2 isa view, partly in section, of a well, after it has been completed.

Figure 3 is a cross-section of the point in plane of red line.

Like letters of referencedesignate corresponding parts inall the gures.

My invention consists in the construct-ion, combination, and arrangement of a well-tube,'consisting of a i driving-point, made as described, and combined with a short obliquely-slotted inner tube, to which it is fastened, and an outer main tube, enlarged at the bottom, which surrounds and protectsthe openings in the inner tube while thetube is being driven, and which is afterwards drawn partially up, so as to uncover the'openings and admit the water, the two tubes being connected together, and locked, when required, in the peculiar manner hereinafter described.

In the drawings, A represents a short inner tubeaixcd tothe driving-point, provided with oblique openings-or slots,b b, (arranged as shown,) for `the admission of the water. C, the driving-point, consisting of a steel or hardened point, d, having a stem or shank, e, which passes through a cast-iron uted portion, f, and screws into the end of the tube A, -or into a reducingmut, g, within the latter, as clearly shown in iig. 1. H is the main tube of the well, the lower end of which screws into an enlargedl portion, H', that surrounds the i inner tube. A ring, z', is arranged within -the portion H', filling the space between the lower end of H and the l top of the inner tube, so that the percussion in driving will be received and divided between both tubes, A H', instead of only one, as in the ordinary methods in use. To prevent the tubes A H' from becoming disengaged during the operation of elevating the latter to uncover the slots in the former, I secure, by welding or other .suitable way, a thirnble or collar, m, to the top of the inner tube, and a similar one, n, in the lower `end of the water-tube, formingshoulders, which, coming in contact after the tube has been raised to the proper point, prevent their separation, asclearly shownin fig. 2.

In driving wells, it is frequently required, from various causes, to elevate the entire apparatus, in which case it is desirable that the two-tubes be locked together, as they are more easily withdrawn in that position, (shown in fig.l 1,) from the fact that the point offers less resistance than it wuld inthe other position, shown in tig. 2. This I accomplish by means 'of ,a pin, o, that ,is made to project a short" distance within the outer tube H', and secures the tubes together by engaging under'the shoulder formed by the thimble mon the top of the inner tube.` In order to permit this pin to passthe shoulder m, when it is required to raise the outer tube in .uncovering the inner one, I provide a slot, pformed in the surface of"'the thimble, ih which it freely slides" when the outer tube is turned, so that the` pin coincides therewith. The tubes are locked together by simply giving the outer one 'a partial turn to destroy that coincidence, when the pin, engaging under the shoulder, pre= vents their sepnration,'as`above stated. The corrugations s Aof 'the cast portionof the point begin at the lower edge, and gradually increase in depth-to the outer edge of the tube H', as'shown in iig. Y.l, and operate to prei vent the point from turning with Ithe main tube in locking 'the latter. They alsov enable the point'to more easily k penetrate the earth, from the cutting-edges that are formed at ,their junction; and by displacing the'earth, and

leaving it impacted in Athei'orm given bythe flutes, leave the hole for the tube so as to present less frictiona surface, and he'nce drive more easily than if it were round. f Y v Constructing the point intw'o parts enables the corrugated and greater part, f, tobe cheaply and readily made of cast metal, while the point can he madeof steel, which is desirable, and comparatively of little cost, owing to the small amount ot' metal required, and capable of being hardened, so as not to batter when driven against stones, which, when small, will be displaced by it. The use of the ring i, by causing the .blows inidriving the tube 'ro-react on both A and H', diminishes the strain, and` tendency to batterand bruise their lower ends;

It has been found from experience that when the slits forvthe admission of the water lare vmade in the outer' tube= they frequently become so plastered up, in passing through strata of clay and moist earth, as to eiectuf ally prevent the entrance ofthe Water, and which the suction from the pump is insuicient to relieve, both on account ofthe iincness of the slits and the adherent quality of the clay. Itis evident that my improvement entirely prevents this difficulty.

A prominent feature consists in making the slot b oblique, in connection with the insulating portion, H, of the pipe, so that when the latter is withdrawn, and water fills the space J, which it occupied, the sand and earth willbe directed downward by the inclined edges of the openings, and fall outside the tube, instead of entering it. The slots are arranged spirally areln'idthe tube A, seas to meet small water-veins in every direction.

I claim the combination of the interposed shoulder-f 0E the driving-point C, and the interposed section of tubing t', with the external tube H H and internal tube .A ,csaid interposed portions being of a. diii'erent material, for tliepurpose of relieving the parts in contact from the injurious effect of the concussion in driving, constructed and arranged substantially as setvforth.

In Witness whereof', I lieve hereunto signedmy-name vin the presence oftwo subscribing witnesses.

H. ARNOLD.
