WELL-DRILLING BIT.
Specification of Letters Patent.
Patented Dec, 2d, 1921.
Application filed February 2, 1920. Serial No. 355,361.
To all QC from. it may concern Be it known that I, OLivnR. J. BOURGOIS, a citizen of the United States, residing at Covington, in the county of Garfield and tltate of Oklahoma, have invented new and useful improvements in VVell-Drilling Bits, of which the following is a specification.
T his invention relates to rotary drills employed for boring oil, or water wells, and its object is to provide a drill bit of novel shape whereby it is given greater eiiiciency in operation as will be pointed out hereinafter.
In order that the invention may be betwiunderstood, reference is had to the accompanying drawing forming a part of this specification, and in said drawing,
Figures 1 and. 2 are elevations of the bit viewed from different sides, and Fig. 3 is a cross-section on the line 33 of Fig. 1.
Referring specifically to the drawing, 5 denotes the body of the bit, the same being of flat elongated contour, and having at its upper end a stem 6 terminating in. an externally threaded portion 7 for attachment of the drill pipe, stem or other operating; clement. Adjacent to the stem 6, the body 5 has an enlargement 8 on each side through which open holes 9 extending lengthwise through the stem 6, for the passage of water or liquid mud generally used for washing out the drillings.
From the two opposite ends of the body 5 project integral lips or wings 10 which are arranged at oblique angles to the transverse axis of said body, as shown in Fig. 3, and Xtend, respectively in opposite directions therefrom. The wings 10 extend throughout the entire length of the body 5 and their outer portions are rounded or curved as shown at 11, the center of the curvature coinciding with the longitudinal center line or axis of the bit. At their upper ends, the wings 10 are beveled or rounded off, as shown at 13, to prevent catching on rocks or other obstructions when drawing the bit out of the well.
Each wing 10 is also dressed at the bottom to a chisel edge 14, and beveled to produce a sharp point 16 at the bottom of the outer edge of the win Between the wings, the bottom of the body 5 has a crotch formed by two cutting edges 1'7 which are inclined downwardly from the center line of the bit in the direction of the wings 10.
terminate in points 16. when the bit is in' operation, the outer sharp points 16 are the first to come in contact with the soil or ther formation, with the result that the outer circle is easily broken, and the inner portion operated on by the edges 17 is out or crumbled with the greatest ease and with less resistance than is encountered with an ordinary drill bit. When loose stones, or pieces of s eel or iron are encountered, the bit will have tendency to keep the same in he center and thus continue in operation, whereas with an ordinary bit obstructions of that kind are forced to the outer edge of the bit against the wall of the hole, causing the bit to jam or stop abruptly, and thus retard the drilling progress.
I claim:
1. A drill bit comprising; a flat elongated body having oppositely facing cutting; ec see at the bottom, said cutting edges being inclined downwardly from the longitudinal axis of the body to form a crotch, the ends of said body having extensions to form side wings which project laterally in opposite directions from the body, and project at the bottom below the plane of the aforesaid cut ting edges, said projecting bottom portions of the wings having oppositely facing cutting edges which extend laterally with respect to and are in advance of the firstmentioned cutting edqes, and form continuations thereof, and said projecting portions of the wings being beveled at the bottom in the direction of their outer edges to produce cutting points at the bottom thereof, and the aforesaid cutting edges of the wings extending downwardly from the first-mentioned cutting edges to the points.
2. A drill bit comprising a flat elongated body having oppositely facing" cutting edges at the bottom which are inclined downwardly from the longitudinal axis of the body to form a crotch, the ends of said body having extensions to form side wings which project laterally in opposite directions from lit) first-mentioned cutting edges, said cutting edges of the Wings also extending laterally With respect to and in advance of the first- 10 mentioned cutting edges.
In testlmony whereof l aflix my slgnature.
OLIVER J. BOURGOIS.
