WELL-SINKING MACHINE.
SPECIFICATION forming part of Letters Patent No. 395,034, dated December 25, 1888.
Application filed November 19, 1887. Serial No. 255,563. (No model.)
To all whom it may concern.-
Be it known that we, WILLIAM B. (OFFIN and JOsEPH R. GOFFIN, both of Bliss, in the county of 'heeler and State of Nebraska,
have invented a new and Improved \Vell- Sinking Machine, of which the following is a full, clear, and exact description.
The object of the invention is to so construct the tube used in drilling the well by IO the assistance of hydraulic pressure that it is made to form a permanent part of the well after water is reached.
The invention consists in the construction and arrangement of certain partsand details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification,
in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is an enlarged front elevation of the drilling-tool and the valvepipe. Fig. 2
is a sectional elevation of the valve-pipe on the line :0 00 of Fig. 1. Fig. 3 is a sectional plan view of the same on the line y y of Fig. 2.
The lower tube, F, of the well-tubing F carries a collar, F in which is secured a valvepipe, L, carrying on its lower end a collar, L,
0 on which is secured the tool-pipe N, carrying the drilling-tool O on its lower end. The drilling-tool O is a fiat piece of steel, which extends into a slot formed in the middle of the pipe N, and is provided at its upper end with 3 5 a shank, 0, fitting into the pipe N above said slot. A bolt, 0 fastens the drilling-tool O to the lower end of the pipe N. The lower end of the pipe N is slightly spread, as illustrated in Fig. 1, so that the water passing down. the
pipe N is spread over the lower surface of the drilling-tool O on each side, so as to wash off all adhesive matter from the said drillingtool. The drilling-tool O is slightly curved on its cutting-edges, and the said drilling-tool is provided in its lower part with the two outting-edges l and 2, forming a point at their intersection, and then extending upward, di-
verging from each other, and then continuing into the vertical and parallel cutting-edges 3 and 4., from which extend the inward cuttingedges 5 and 6, which are joined to the edges of the shank O.
In the valve-pipe L are formed two rows of apertures, L placed close together, said rows being placed diametrically opposite each other, as illustrated in Figs. 2 and 3. Each row of apertures L is covered on the inside by a valve, P, secured at its upper end by rivets P to the valve-tube L. In the lower end of each valve-pipe P is formed a vertical slot, P into which extends a rivet, Q, secured to the lower end of the valve-pipe L. The slot P in each of the valves P permits an upward motion of the lower end and inward bending of the said valve whenever the water from the veiinpresses strongly through the apertures L against the said valve, or when the water is drawn inward from the vein when operating the well-pump in the usual manner. The water can then pass on account of the bending of the said valve on the inside of the valve-pipe L into the latter and up through the tubing F to the outside of the valve.
The valve-pipe L is preferably covered by a wire-gauze, R, so as to prevent heavy substances from passing into and through the apertures L but the only object of the V alves P is to cause the water in the drilling operation to be forced through the end of the pipe; but these valves do not interfere with the free inflow of water after the vein has been reached.
In the upper end of the tool-pipe N is inserted a hollow wooden plug, S, carrying on its lower end a valve, T. This plug and valve are specially adapted for deep wells in which quicksand is present, and they serve to prevent an upward movement of the quicksand into the pipes L and F. The plug S is made of wood, so that it can be destroyed when it becomes necessary to locate the valve-pipe L in sand or line gravel, for the reason that in some veins of water the sand contained in it is so fine that it obstructs a free flow of water through the gauze R, and hence the plug and its valve T must be removed, which is done by an auger secured to piping and let down the tubing until the auger strikes the wooden plug. The piping is then turned so that the auger bores out the plug. Sufficient sand is oo now removed from the bottom of the well below the tool by a sand-pu1np or other means, to form a cavity suttieicntly large to enable the tine substances which obstruct the free flow of water through the gauze R to settle 1 down into the said cavity. A solid wooden plug is then driven into the tool-pipe N, which is thus closed up.
The drilling-tool 0 usually descends at a speed of about two inches to one revolution of turning, and the vertical cutting-edges 3.3 and lserve to leave the wall of the well-hole smooth and regular. edges, 5 and ti, provide against resistance when necessary to raise the piping any given distance subsequent to a completion of the well. pressure of the water in the vein in order to supply the cylinder of the pump. The slots 1 allow a slight upward motion and insure a free flow of the water through the screen or gauze R and the perforations L It will be understood that when the two valves meet at their extreme inner centers when pressed inward they do not obstruct the free flow of water into the piping above. In sinking wells by hydraulic force it often occurs that the operator misjudges the most desirable locality to establish the perforated valve-pipe L. After the operation ceases, the pump is started and the mistake isapparent. Then it is best to remove the pump and pro ceed the same as before the valve-pipe L was located. If the pipe at the first trial is supposed to be too deep, the downward flow of the water shuts the valves P, eausin g the upward How to hold back the yielding strata, and the pipe can then be raised or lowered at will.
Having thus fully described our invention, we claim as new and desire to secure by 'Letters Patent- 1. The t'tnllillllflllUll, in a well-boring machine, of a perforated tube having imvardopening valves with an o wn-ended tool-can rying tube connected to its lower end and a downward-opmiing valve below the firstnamed valves, whereby sand or other solid matter is prevented from rising through the tool-tube and closing said inward-opening valves, and the said valves will close and the lower one open when hydraulic pressure is applied in drilling, substantially as set forth.
2. In a well-boring machine, the combination, with the tube having a vertical series of The upper cutting- Thc valves ll, yield inwardly to the i apertures, of a flexible strip secured to the 1 inside of the tube, covering said apertures, i and having a sliding connection with the tube,
substantially as set forth.
I). In a well-boring machine, the combination, with the tube having a longitudinal series of apertures, of a tlexible strip secured to the inside of the pipe over said apertures, one end of the strip being slotted and having a headed guir'ling-pin or rivet passing therethrt'iugh, substantially as set forth.
l. The coml'iination, with the open-ended tool-carrying tube and the perforated tube connected to the upper end thereof and provided with an inward-opening valve for said perforations, of an lllifOllllQtllftlG short wooden tube closed at its lower end against upward pressure by a down \va rd -openin val ve,whereby'the wooden section may be destroyed when its valve is no longer necessary to the successful operation of the said inward-miening valve, substantially as set forth.
In a well-sinking machine, the combination, with a valve-pipe secured to the well tubing and provided with rows of {\{Mfl'iii'll't'lS and a wire screen or gauze covering the outside of said valveq'iipe, of valves held on the inside of said valve-pipe and operating over said rows of apertures, a tool'pipe held on the lower end of the said downward-openin g valvepipe, and a valve held in the said tool-rape, substantially as described.
(3. In a well-sinking machine, the combination of a main pipe, a perforated tube connected to the lower end of. said pipe, a drillingtool connected to the lower end of said perforated pipe, and valves located within said perforated tube coveri n g the perforations and opening inward, sul'istantially as shown and described.
7. In a wcllssinhing machine, the combination of a main tube, a drilling-tool with a hol low upward extension, a perforated tube located between said main pipe and (billingtool, having in\Vard01)ening valves over the perforations, and a valve ope]1ingdownward, located between the said nwtoratc-d tube and the drilling-point, sl'ibstantially as shown and described.
