SELF-BAILING WELL-TGQL.
To all whomit maq concern:
Be it known that I, LYLE GAnmsoN, a cltizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in SelfjBailing Well-Tools, of which the followmg is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.
This invention relates to well tools, and more particularly to well tools of the cable pe. v The main object of this invention is to provide a device of the above character constructed and arranged so that the means which raises and lowers the tool, also operates to positively pump the water and drill cuttings from the well.
Still another object of this invention is to devise a tool of the above character in which the water and drill cuttings are bailed from the well through the body of the tool by a positive pumping means arranged within the tool.
Another aim of this invention is to provide a tool of the above character in which the bailing pump arranged within the body of the tool is positively operated from the 7 ably connected to'the shank by means of a drill cable through the intermediary of a member having a rigid connectlon with a portion of the pump and a yielding COIHIGC-r tion with the tool.
One of the important features of this invention relates to the arrangement of inlet and discharge conduits in the tool whereby the automatic pumping action will draw water from the point at which the drill iscutting and positively force the same in one direction only through the body of the tool and out through the top thereof.
Another purpose of this invention is to provide a tool arranged as described with a telescopic connection with a discharge conduit so that the water and drill cutting may be discharged from the tool during the continuous reciprocation of the same.
Another most important feature of this invention resides inthe fact that the device can be used with practically any standard bit, and it is also interchangeable with the standard tools and does not require any change or addition in the standard drill glhese and other objects will in part be Specification of Letters Patent.
obvious and will in part be hereinafter more tion; 7
Fig. 4 is a modified view of the means for inclosing the lower end of the spring surrounding the drill rod, and
. Fig. 5 is the modified manner of arranglng the inlet openings around the top of the b1t instead of disposing the conduits through the bit as in Figs. 1 and 2.
In general, the tool comprises a shank and bit adapted to be vertically reciprocated by means of a rod connected with the drill cable, which rod passes directly through the longitudinal axis of the shank and is yieldspring, The rod has rigid therewith a valved piston which works in the chamber in the shank and which chamber has communicating valved passages with the base and upper ends, respectively, of the tool, so that when the drill cable is raised, the piston will likewise be raised before the tool vshank moves, due to the yielding connection between the drill rod and the shank, thereby initiating a pumping action within the pum in thetool shank to force water and dril cuttings which have previously passed into said chamber from the base of the tool out through the top of thetool. Upon the descent of the drill cable, the other cycle of the self-bailing operation is completed.
Referring more particularly to the accompanying drawings, the tool comprises a shank preferably composed of an upper tube 1 connected to a lower tube 2 by means of a suitably threaded connection 3 for the proper assembling of the tool. These elements, when assembled, provide a unitary shank having an upper pumping chamber &
and a lower chamber 5 connected by means of a suitable number of conduits 6. Passing longitudinally through the tube 1 an threaded connection 3 and projecting into the lower chamber 5 of the tube 2 is arranged the usual drill rod 7 provided at its upper end with an eye 8 connected to the usual drill cable 9. The lowermost end of this rod 7 is provided with a collar 10 between which and-the threaded connecting member 3 is arran ed a coiled spring 4 in t e tube 1 communicates at its upper end with a conduit 12 extending lengthwise of the tube 1 and opening through the top thereof. The connection between the chamber 4 and the conduit 12 is controlled by a one-way valve, herein shown as the ball 13, provided with an abutment 14 to prevent it from straying from its seat. As shown in the drawing, this valve opens upwardly. Rigidly connected with the drill rod 7 and arranged for reciprocation within the pumping chamber 4 is a piston 14' of any desired construction. This piston is preferably shown as concentrically surrounding the rod 7 and is provided with a suitable number of ports 15 controlled by valves of any desired type, herein shown as ball valves 16 provided with cages 17 to hold them adjacent their seats. These ball valves open upwardly. The chamber 5 communicates by means of a lower conduit 18 with the base of the tool and the port controlling this conduit is controlled by aone-way valve which opens upwardly. As shown in the drawings, this exit which is arranged adjacent the base of the tool, may either dischar e just above the bit as in Fig. 5, or may disc arge through the body of the bit at the base of the cutting edge as shown in Figs. '1 and 2, in which latter case the bit is provided with an internally arranged longitudinal conduit 1920 discharging as at 21 adj acent the cutting edge. In the preferred arrangement, this conduit 19--20 is controlled by a ball valve 22 which is adapted to move upwardly from its seat against the grate 23. In Fig. 5 a similar arrangement 1s provided except that the conduit 24, exits as at 25 adjacent the head of the attached bit 26 and at a suitable point as at 27 is provided with a onewaIy ball valve 28 having the usual grate 29.
n Fig. 4 I have shown a slight modification of the internal arrangement of the shank in which the lower end of the coiled spring 11 surrounding the drill rod is inclosed in the chamber 31, the conduit 18 being connected to the communicating passages 6 in the threaded connecting member 3 by means of suitably disposed conduits 30.
In order to permit the tool to continuously reciprocate and at the same time have a flexible connection with the water and drill cuttings discharge conduit, there is provided 11. The chamber.
'may also be provided with an air conduit 34 connected with a suitable source of air pressure to assist in agitating and lifting the cuttings. This last feature may be omitted, if desired.
The operation of the device is as follows:
When the cable 9 is lifted, the piston'14 is raised with the drill rod without moving the drill tool until the spring under the proper degree of tension as shown in Fig. 3, at which time, of course, the drill tool will move upwardly with the cable 9. Prior to the movement of the tool shank and while the piston 14 is being drawn upwardly relative thereto, water and drill cuttings previously accumulated within the chamber 4 are forced upwardly by-the piston 14 and out through the conduit 12 controlled by the upwardly moving'ball valve 13, the valves 16 remaining on their seats due to the pressure of the water above. Simultaneously with the upward forcing of the water, a corresponding sucking effect is created beneath the piston 14' in the chamber 4 which tends to draw water and drill cuttings from the base of the tool through the conduits 25 or 20 past the upwardly moving ball valve 22 or 28 into the conduit 18 and thence through the communicating conduit 6 so that as the piston 14 moves upwardly, water and drill cuttings will fill in the chamber 4 beneath the piston. This all occurs on the upward stroke of the drill tool. When the cable 9 permits the drill tool to descend, no pumping action, occurs until the tool strikes the bottom of the .well, at which time, the weight of the tool havin been taken from the cable,'the spring wi 1' extend and the drill rod 7 and connecting piston 14' will move downwardly relatively to .the drill shank 1 from the position shown 11 is put' in Fig. 1. At this time the water and drill valves 22 are now seated downwardly and prevent the esca e of the water. When the cable 9 again li s the tool, the cycle is repeated as above described.
It is evident from this description of the invention that a tool of this character provides a positive self-bailing action due to the tars-Patent, is-- l. A device of the character described comprising a well tool provided with a pumping chamber and a valved conduit connecting said chamber with the base of said tool and with a point of discharge outside of the well, means for raising and lowering said tool, a spring interposed between said means and said tool, a valved piston connected to said means and reciprocable in said pumping chamber whereby on the raising and lowering of said tool, said piston draws the water and drill cuttings from adjacent the base of said tool and discharges the same outside of the well.
2. A device of the character described comprising a well tool-provided with a pumping chamber, conduits connecting said chamber with the base of said tool and with a point outside of said: well, a drill rod slidable through one end of said tool, a piston connected with said rod and reciprocable in said chamber, a spring interposed between said rod and said tool and means for raising and lowering said tool by means of said drill rod wherebysaid piston o crates to'draw'water and drill cuttings fr m adjacent the base of saipli tool and discharges it outside 01E- said we 3. A device of the'character described comprising a well tool provided with a pumping chamber, a valved conduit connecting with said chamber and having'an inlet port adj acent the base, a valved conduit connecting said chamber with a point of discharge outside of said well, a drill rod, a valved piston connected to said rod for reciprocation casings and said collar and having its end terminating in the other recess, a spring in said other recess interposed between said, end and said collar, and a valve piston fixed to said drill rod and reciprocable insaid pumping chamber, valved conduits connecting. said pumping chamber with an inlet port adjacent the base, and with a, discharge point outside of the well. a
In testimony whereof, I afiix my signature.
