WELL DRILLING TOOL Filed Oct. 19, 1927 an uc'uto". 13%6 K uQ u "o lemme.
Patented Dec. 24, 1929 BOYD K. APPLEMAN, OF BEAUMONT, TEXAS WELL- DRILLING TOOL Application filed October 19, 1927. Serial No. 227,265.
This invention relates to deep well boring tools and provides means for rapid drilling through gumbo and other strata encountered in boring artesian, oil and similar deep walls.
In accordance with the present invention an attachment, partaking of the nature of a tool guide and mudqnixer, is supplied and comprises a stem and blades, said stem being adapted to have a drill point and an operating rod fitted thereto.
While the drawing illustrates a preferred embodiment of the invention it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.
For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawing hereto attached, inwhich,
Figure 1 is an elevational view of a deep well tool embodying the invention.
Figure 2 is a sectional View of the guide, reamer, and mud mixer.
Figure 3 is a sectional view on the line 3-3 of Figure 1.
Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.
The invention is directed to an attachment :5 which comprises a stem 1, and blade 2. The
stem 1 may be of any length and diameter and usually consists of a length of pipe which is threaded at opposite ends to admit of a drill point 3 and an operating rod 4 being .& coupled thereto. There may be provided as many blades 2 as may be deemed necessary according to the particular work and nature ""of the strata to be bored. When more than one blade 2 is provided the several blades are located at intervals inthe length of the stem 1, and are disposed at different relative angles. The blades 2 may be applied to the stem 1 in any determinate way, and, as shown are fitted in openings formed in the stem and may be secured by welding or in any preferred way. The blade 2 projects beyond the sides of the stem a given distance to form cutters for reaming the opening and vanes for mixing the mud, as well as guides for centering the stem and drill bit. When one blade only is rovided it occupies a position at a right ang e to the drill bit and when two blades are'provided they are disposed at a right angle to each other, as indicated in the drawings, thereby centralizing the stem in the openings. The blades 2 are flat and their longitudinal edges are parallel and beveled to form cutting edges, as indicated most clearly in Figurefi of the drawings. The corners of the blades are cut away to facilitate the advance of the tool and the withdrawal thereof when it is required to remove the tool from the well.
Having thus described the invention, I claim:
A tool joint and reamer for a deep well drilling apparatus comprising a stem provided with transverse passages spaced from each other longitudinally thereof and disposed transversely of each other, a bit at the lower end of said stem of greater width -ihan the diameter of the stem and having its side portions projecting therefrom, and blades passed through the passages of said stem and each consisting of a metal plate of the same width as the bit and having its end portions projecting from opposite sides of the stem and its end edges sharpened and extending vertically in the planes of the side edges of said bit, the upper and lower ends of the projecting portions of said blades extending at an incline from the stem to the end edges of the blades to facilitate advancement and withdrawal of the tool.
In testimony whereof I aflix my signature.
. BOYD K. APPLEMAN. [1... s.]
