Specification of Letters Patent. Patented Apr. 19, 19 21.
Application filed April 28, 1919. Serial No. 293,313.
To all whom it may concern: 7
Be it known that I, LORAN E. NEBERGALL, a citizen of the United States, and a resident of Omaha, in the county of Douglas and State of Nebraska, have. invented. certain new and useful Improvements in Deep- Well-Drilling Devices, of which the followin is a spec1fieation. y invention relates to toolsand appllances for-boring Artesian and Oll wells. It is the object of my invention to provide an auger-stem or drill-bar such that the use thereof will insure the production of a straight vertical hole in broken or slanting formations, or under any circumstances such that there would ordinarily be a tendency to deflect the drill or bit and roduce a slanting or non-vertical hole. I of my invention is to rovide for forming an auger-stem havin t e foregoing characteristics, by means 0 members attachable to stems or drill-bars of the ordinary and common form, whereby a stem of the improved form may be produced without waste or loss of the stems now in use with standard deepwell boring equipment.
In the accompanying drawings Fi re 1 is a vertical sectional view showing 1n use a typical string of drilling tools including an auger-stem constructe in accordance with my invention, Fig. 2 is a side view on a larger scale, of the auger-stem alone, Fig. 3 is a horizontal section of the stem on the line 33 of Fig. 2, Fig. 4 is a side view of a portion of the stem, showing aslightly modified form of. the wings, and Fig. 5 is a transverse section on the line 5-5 of Fig. 4. a
In carrying out my invention I provide an auger-stem having a plurality of ribs or wings which extend out radially therefrom and are continued substantially throughout. the'length thereof, said wings having at their outer edges flanges which extendconcentrically with the main body of the stem and provide a wide guiding surface for engaging the sides of the hole in which the stem is used.
In the construction shown in Figs. 1, 2
and 3, I provide metal plates having intermediate transversely curvedportions 6,with integral wings 7 at each longitudinal edge thereof extending approximately radial to the axis of curvature of the portions 6, and
are connected by rivets 9, the wings being drawn together during the riveting operation so that the curved portions 6 are pressed in upon and clamped securely to the stem 10. The wing-plates are preferably made up in sections of limited length, such that a p urality of the sections are required to equal the entire lengthof the stem, and the gered relation to each other in t e adjoining sections, or so that the wings of an section are at circumferential positions intermediate the. wings of the adjoining sections.
In the modified structure shown in Figs. 4 and 5, the curved plates have radially extending wings 70 which are secured together by means of rivets 90 or the like, and the plates thus held upon the stem. At the outer edges of the wlngs 70 angle-bars 80 are secured thereto by means of rivets 81, the outer flangesof the angle -bars being slightly curved so as to extend concentrically with the stem, similarly to the flanges 8 in the form first described. Aside from the added wing-sections above described, the auger stem may be of the ed pin 11 and an ad'acent wrench-square 12,
and at the lower en having the usual internally threaded box 13 and wrench-square l4.
In theuse of the winged stem for ordinary 'drilling operations, a suitable drill or bit 15 is connected with the lower end of the stem, and to the upper end thereofis connected the usual accessory tools, such as the jars 16, shown in Fig. 1. At the upper end of the string of tools a rope-socket 17 :is provided, from which the drill;rope 18 extends up to the usual operatinginechanism. It will be seen that, as the stem and bit are rigidly connected with each other, and the flanged outer portions of the wings on the stem have a bearing on the sides of the hole -for a great distance above the bit, the stem will serve as a prevent lateral efiection thereof when iruide for the bit and will or stagregular, broken orslanting formations are encountered. Thus the hole, having once been started on a true vertical axis, will continue to be produced along a vertical line, and the bit cannot be turned aside by any irregularities of the strata or formations through which the hole is made. Obviously the production of a straight hole greatly facilitates the subsequent operation of sinking the casing or tubing withinthe well. The winged stem may be used advantageously in connection with an under-reamer, when placing the pipe or casing within the hole, the reamer being operated below the lower end of the pipe in such proximity thereto that a large portion of the stem will he within the pipe and guided thereby.
The outside diameter of the winged stem should, of course, be substantially the same as that of the hole which is produced, or, when used with an under-reamer, the stem should be of such diameter as to fit slidably within the pipe.
Besides guiding the bit and preventing lateral deflection thereof at the bottom of the hole, the winged stem provided by my invention serves to churn and agitate the debris in the hole, keeping the same in a fluid condition and preventing the formation of mud-rings.
The wing-forming plates attached to the auger-stem may have a slight twist or incline, so as to extend helically about the axis of the stem, like the WlD 'S of the integral stem shown in United %tates Letters Patent No. 1,188,982, issued to me June 27, 1916, and when so formed, the effect thereof will be to produce the rotary or whirling movement of the tools described in said pat-ent, as wellas the other effects herein noted. The principal advantage of the present structure over that shown in m above mentioned patent, lies in the facility and economy with which ordinary auger-stems may be converted into winged stems for use in any size of hole, by attachin to said ordinary stems the plates for forming the wings. It Willbe noted, further, that the wings provided by the structure herein dis closed, and having the flanges 8 or 80 at the outer edges thereof, form a more extended bearing surface, for engagement with the sides of the hole, than can be produced With wings formed integrally with the stem, unless the latter be made of excessive weight.
Now, having described my invention, What I claim and desire to secure by Letters Patent is:
In a deep-well auger-stem having a long a plurality of parts extending out radially of the stem'body and continued longitudinally thereof, and the radially extending parts being circumferentially interspaced in adjoining sections.
