WELL-BORING APPARATUS.
.SPECIFICATION formingpart of Letters Patent No. 672.097, dated April 16, 1901.
Application filed March 15. 1900. serial No. 8,860. (No model.)
To all whom t may concern:
Be it known thatl, FRED A EASTMAN, a citizen of the United States, residing at Litchfield, in the county of Meeker and State of Minnesota, have invented certain new and useful Improvements in Well-Boring Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in means for boring Artesian wells; and the main object of the invention is to provide means and processes whereby an Artesian or similar well tube of any diameter and with an external strainer may be sunk in the ground and then have its bottom end closed, so that the Water must enter through the strainer. This object I attain by the novel construction, arrangement, and use of parts hereinbelow set forth, and illustrated in the accompanying drawings, in which- Figure 1 is a central longitudinal section of the completed well with the boring tube or rod partly raised for removal. Fig. 2 is a longitudinal central section of the well and boring-tube when the well is nearly completed. Fig. 3 is a section on the line a, a in Fig. 1.
Referring to the drawings by reference characters, 5 is the well-tube to be sunk in the ground. On the lower end of this tube is secured the ring-shaped shoe 6, with the internal coarse and flat-topped thread 7, adapted to receive the similar thread 8 of a tubular attachment consisting of the tubes 9 and 10, which may be made integral, but is preferably made in two sections and screw-threaded together at 1l, so that the lower end of the upper section l0 forms a seat 12, up against which the valve 13 is normally pulled by the spring 14. rlhe valve-stem 15 is guided in the cross-bar 16 and has its downward movement limited by the pin 17. The lower end of this attachment is formed with a sharp annular edge 18, which loosens the sand and earth during the sinking of the attachment from the position shown in Fig. 2 to that in Fig. 1. The upper end of the attachment is provided with two opposite notches, like 19, for the pin or bolt 2O of the drilling-tube to engage when the attachment is to be secured in its place, as will be further explained below.
The lower portion of the tube 5, between b and b, is provided with external longitudinal grooves 21, (see Fig. 3,) from which large apertures 22 open into the interior of the tube. The said grooved portion of the tube is cov- .ered with a finely-perforated strainer to prevent sand from entering with the water. The screw-threads 24 on the attachment and in the lower part of the coupling 25, secured on the drill rod or tube 26, lare left-handed threads.
In the operation of sinking the well the tube 5, which is made in any required number of sections, according to the depth of the well, is placed with its shoe 6 in the hole started in the ground. The hollow drill-rod 26 is then provided with the usual hollow drill, (not shown,) secured in the lower end of the coupling 25 by the threads 24, and, if so desired, also by the bolt or pin 20. The drill and rod are then lowered into the main tube and given a plunging and rotating motion, as usual, while a stream of water is circulated down through the drill-tube and drill and up between the drill-tube and the outer tube, as is usual in digging such wells, carrying up and out on the ground the loosened sand and earth. During this process the attachment 9 10 is not in the well, and the drill is gu'ided by the top of the thread 7, which is therefore made iat and broad, so that the thread will not be injured by the sides of the drill. When the drilling is thus finished, the drill-rod is eX- tracted, the drill removed from it, and in the drill-coupling 25 is secured by the left-hand threads 24 the attachment 9 10, which is now lowered down and agitated, while a current of water is sent through it, as indicated by the arrows in Fig. 2, until its coarse thread 8 is at least partly screwed into the thread 7, when the resistance from the friction on the coarse threads and of the sand which can no longer escape upward between the pipes causes the left-handed thread 24 to unscrew. The drill-rod is then raised, the pin or bolt 2O inserted, and the rod lowered again until said pin engages the notches 19 in the attachment, which is then screwed home tightly in IOO the shoe 6, Where it remains permanently, excepting when cleaning of the well may require its temporary removal. The valve 13 being normally impelled upwardly by its spring excludes sand and water from entering the pipe from below, while the strainer 22 23 admits only water to enter. The drill-rod is finally removed from the well and the latter is completed.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-
1. In a well-boring apparatus, the combination with the well-tube having a cylindrical strainer about its lower end, a shoe G permanently secured below the strainer and being of a lesser inside diameter than the tube, said reduced part of the shoe having an internal coarse and fiat-topped thread adapted to resist the wear of the well-drill when operating through the shoe; a tubularattachment adapted to be secured in said coarse thread, and having an upwardly-spring-closed valve and the cylindrical sharp projection or extension 18 at its bottom end, substantially as and for the purposes set forth.
2. In awell-boring apparatus, the combination with the well-tube having its bottom end reduced as to its inside diameter, and provided with an internal, coarse thread adapted to stand the wear of the drill reciprocating or otherwise working therethrough, of a valved tubular attachment for closing the said opening in the bottom of the main tube after the drilling is done, said attachment having threads at or near both ends, one being a right and the other a left hand thread, the upper end also having the straight, upwardly-open notches 20 in it, a well-borin g rod or tube having threads matching the threads of the upper end of the attachment, and a removable, transverse pin or bolt adapted to be inserted temporarily and engage the notches in the attachment, and the lower thread ofthe attachment being fitted t0 the said coarse threads in the lower end of the well-tube, substantially as and for the purpose set forth.
In testimony whereof I affix my signature in presence of two witnesses.
FRED A. EASTMAN.
