A TTORNEYS GEORGE G. REEVES, OF HUMBLE, TEXAS.
DRILLING APPARATUS.
Specification of Letters Patent.
Patented Oct. 25, 1921.
Application filed April 11, 1921. Serial No. 460,477.
To all whom it may concern:
-Be it known that I, GEORGE Gr. REEvEs, a citizen of the United States, residing at Humble, in the county of Harris and State of Texas, have invented certain new and useful Improvements in a Drilling Apparatus, of which the following is a specification.
This invention relates to new and useful improvements in a well drilling apparatus and has particular relation to an improved form of break-out pin employed in screwing together or unscrewing joints of pipe.
One object of the invention is to provide an apparatus of the character described which has been specially designed for application to a rotary and is used in connection with a pipe tong for screwing together or unscrewing the joints of pipe used in drilling.
Another object is to provide a break-out pin which may be readily released from the pipe tong.
A still further feature resides in the provision of a break-out pin which is of simple and durable construction and may be cheaply manufactured and readily applied to the work.
With the above and other objects in view the invention has particular relation to certain novel features of construction, opera tion and arrangement of parts, an example of which is given in this specification and illustrated in the accompanyng drawings, wherein Figure l is a fragmentary vertical sectional view of a rotary, showing the breakout pin applied to the work.
Fig. 2 is a transverse sectional view of the break-out pin taken on the line 22 of Fig. 1.
Fig. 3 is a lower end view of the section of the pin.
Fig. 1 is a side view thereof.
Fig. 5 is a lower end view of the anchor post employed, and
Fig. 6 is a side view thereof.
Referring now more particularly to the drawings, the numeral 1 designates the rotary base plate, the niuneral 2 designates the rotary table which is mounted on said base plate and the numeral 3 designates the driving pinion of the table. The numerals 4 and 5 designate upper and lower sections, respectively, of the drill stem, said sections being connected by a collar 6. In applicaupper tion, when it is desired to screw together or unscrew the pipe sections the lower section is held in the rotary table against rotation by means of pipe-engaging slips 7 of well known construction and use. The rotary table has a deep socket 8 provided to receive the lower end of the anchor post 9, said anchor post forming the lower section of the break-out pin. The section of the anchor post above the table is formed square in cross section and has the lateral projections 10, 10. The upper end of said post has a slight bevel, as at 11. The upper section 12 of the break-out pin is tapered from the lower to the upper end thereof and in cross section is elliptical in form, as shown in Fig 2, and is provided with the grip ring 13. The lower end of the section 12 is provided with a socket 14 which receives the upper end of the anchor post 9, the upper end of said socket being beveled to conform to the beveled upper end of said anchor post. When the section 12 is seated on the anchor post the depending projections 15, 15 thereof engage behind the lugs 10. The beveled end of the anchor post 9 contacts against the beveled inner end of the socket 14: and the projections 15 interlocking with the lugs 10 hold the section 12 of the break-out pin against falling over when not in contact withthe pipe tong. The numeral 16 designates a pipe tong of the usual construction, which is engaged around the upper section 4 of the pipe. The rotary is then turned in the usual way and the breakout pin will be carried around against the tong and as the rotary continues to turn the pipe section 4 will be turned with it and screwed to or unscrewed from the section 5. When it is desired to release the break-out pin from the tong the upper section 12 is pulled outwardly through the instrumentality of the grip ring 13 and disengaged from the handle of the tong. On account of its upward taper, a very slight outward pull will re lease the pipe from the tong. It is now common practice to use a rod or bar whose lower end is inserted in the socket 8 and whose upper end engages with the tong, but this rod is very difficult to release from the tong and when used a hammer or other implement is required to disengage the bar from the tong in order to withdraw said bar from the socket. The type of break-out pin herein described and shown has been designed so that when the pipe section is screwed together it may be readily released from the tong and then removed from the table so as to be out of the way.
What I claim is 1.. A break-out pin formed of two sections,'one of which tapers from its lower to its upper end and whose lower end isforined with a socket, and the other of which has its upper end formed to fit into said socket.
2. A break-out pin formed of two sections, one of which tapers from its lower to its upper end and whose lower end is provided with a lateral socket and spaced projections, and the other of which has its upper end formed to fit into said socket, and lugs carried by the last mentioned section with which said projections engage.
A break-out pin including an anchor post whose upper end is beveled, and an upwardly tapering section whose lower end is provided with a lateral socket into which the upper end of said post snugly fits.
4. A break out pin including an anchor post whose upper end is beveled, and an upwardly tapering section whose lower end is provided with a lateral socket into which the upper end of saidpost snugly fits, lateral lugs carried by said postand spaced projections carried by said section and interlock ing with the lugs.
In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
