DRILL COLLAR,

APPLICATION FILED una, 1911;.

Patented Mar. 16, 1915.

IlllllllIllll-IIIIII V the bore.

GEORGE S. MYERS, OF ELECTRA, TEXAS.

DRILL-COLLAR.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application led April 8, 1914. Serial No. 830,474.

T0 all rwhom it may concern:

Be it known that l, GEORGE S. MYERS, a citizen of the United States, residing at Electra, in the county of Wichita and b'tate of Texas, have invented new and useful Improvements in Drill-Collars, of which the following is a specification.

This invention relates to drill collars and in particular to collars used upon rotary drills of the type which are water-flushed. In drills of this type, it is the usual practice to employ a collar which is threaded onto the lower end of the operating drill pipe and is adapted for threaded connection with the bit. The threaded connection between the bit and collar, though substantially watertight, is objectionable for the reason that the threads are apt to become worn and d istorted by the incessant shock incident wlth the impact of the bit against the rock through which it is cutting, whereby the bit is apt to become detached while operating 1n A detached bit, as should be readily understood by persons familiar with the art to which this invention relates, is always a source of great inconvenience,` and, when it can not be recovered, it necessitates the abandonment of the bore, which means that a new bore must be drilled, possibly after days and weeks of fruitless effort exended upon the original bore. It is, thereore, my purpose to provide a drill collar having means embodied therein for securing the drill bit positively thereto and' in a manner which precludes the possibility of accidental detachment while in use.

A further object of the invention is to provide a collar of this character wherein the means for securing a drill bit thereto is in the form of a wedge-shaped key which extends transversely through slots provided in the same.

A still further object is to provide a securing key of this construction which is adjustable within the slots so as to permit effective binding of the bit in position, but which is provided with means fd'r preventingr loss of Ithe flushing liquid through the collar slots, though the flow of the same onto the bit is uninterrupted.

The invention consists in the features of construction, combination, and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of the collar mounting a bit upon a drill pipe, the latter being broken away; Fig. 2 is a longitudinal sectional view on line 2--2 of Fig. 1; and, Fig. 3 is a transverse sectional view on line :5 -3 0f Fig. a

In the drawing, the numeral l designates a portion of the ordinary form of drill pipe, whose lower end is externally screw-threaded at 2 for engagement within the threaded socket 3 provided in the upper end of my improved collar 4. This collar is provided in its lower end and in communication with the socket 3 with a longitudinally tapered socket 5, which is substantially rectangular' in transverse section, for the snug reception of the shank 6 of the drill bit 7. The bit socket 5 of the collar is provided in its opposite side walls with longitudinally extending grooves 8 which lead downwardly from the socket 3 and form liquid ducts which are adapted to register with the conducting grooves 9 formed in the corresponding sides of the bit. The collar is provided further u ith a transverse key slot 10 in communication with the socket. This slot is adapted to receive a` diametrically adjustable securing key 11, the lowerV face 14 of the latter lbeing disposed at right angles to the axis of the drill collar'irrespective of adjustment. This key is adapted to extend through the slot 15 provided in the shank 6 of the drill bit with its inclined upper face 12 in active engagement with the inclined upper wall 13 of the said slot. The small and large ends of the key 11 are screwthreaded as at 17 and 18 respectively. Adjusting nuts 19 and 2O are engaged with the said threaded ends 17 and 18 of the key and are adapted to be countersunk withi'n enlarged recesses 21 and 22, which are provided in the sides of the collar in communication with.the key slot. These recesses are constructed larger in diameter than the key slot so that the marginal edges of the adjusting nuts will extend past the edges of the slot so as to seal the slot and thus prevent leakage of the flushing liquid there: through. i

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent that the securing key 'ill fasten the bit shank securely within the collar socket, so as to obviate danger of accidental detachment thereof, and that the nuts oy which the key is adjusted, either in attaclung or detaching the same, will serve lill im pi'i'wn. `ifftfirfiay# if: thi; prima* opinitmn 0l the il l Unfall is# i, du lower @ml uit the Suid lll i'i the sui( sucll, and u wedgehaped securing key afipled w be nwimtied afustallly within the smid key sl@ 5B.
