WELL-DRILLING DEVICE.
Specification of Letters Patent.
Patented Feb. 10, 1920.
Application filed'ilune s, 1919. Serial No. 301,507..
ITO all whom it may concern:
Be it known that I, WALTER LEE Cannon, a citizen of the United States, residing at Humble, 1n the county-of Harris and State 6 of Texas, have invented certain new and usel0- percussion type, adapted to be attached to the lower end. of a drill stem for drilling Another object of the invention'is to provide a drilling tool, attached to the lower end of the drill stem, and equipped with a bit and a reciprocating hammer, said hammer being actuated against the bit by hydraulic impulses, and withdrawn therefrom by mechanical means, said bit being therebyactuated against the bottom of the bore to disintegrate theformation thereof.
With the above and other objects in view, the bore to dlsintegrate the same.
the invention has particular-relation to certain novel. features, of construction, opera- The upper end of the shank is formed into anenlarged head 12, and threaded onto said shank below the coupling, there is a collar 13, said head and collar being spaced apart a sufficient distance to permit a limited reciprocation of the shank and bit. The hammer 5 has an annular rib 14, spaced above the spider 7 and surrounding said hammer and interposed between said spider and rib thereis a strong coil spring 15.
In operation the device is let down into the bore until the bit rests on the bottom thereof and the stem is then filled with water, or other fluid. A force pump, "(not shown) is then connected to the upper end of the stem and with each forward stroke thereof, an impulse is transmitted through.
said fluid against the upper end of the hammer which is thereby actuated against the head of the shank 10, and the bit is thereby driven against the formation at the bottom of I Upon back stroke of the pump, the pressure is released, and the spring 15 will lift the bit out of contion and arrangement of parts, an example tact with the formation preparatory to anof which is given in this specification and other stroke. he stem, during drilling opillustrated in the accompanying drawings, erations, is slowly turned by any well known the lower on the line 55 of Fig. 1.
wherein:
Figure 1, is a vertical sectional view of art of the device. Y 1
Fig. 2, 1s a vertical sectional view of the. upper part thereof. l Fig. 3, is a point view of the bit. 1 Fig. 1, is a transverse sectional view taken 85 on the line 4-4: of Fig. 1, and
Fig. 5, is a transverse sectional View taken Referring now more particularly to the drawings wherein like numerals of reference 40 designate similar parts in each of the figures, the numeral 1, refers to a tubular barrel which is attached to the lower end of the drill stem 2, by means of the collar 3. Within the collar 3, there is a'stufiing box 4 through which the cylindrical hammer threaded onto the lowerend ofthe barrel 1.
The lower'end of this coupling 8 has an inwardly extending annular shoulder 9, forming a bearin for the shank 10 of the bit 11. This shan is splined in the bearing so that it will reciprocate therein, but be prevented from turning relative thereto.
form of rotary and the bottom of the bore is thus gradually disintegrated and bore thus deepened.
In order to wash away the cuttings from the --bit, the entire device is elevated until the bit is lifted clear of the bottom of the bore, the head 12, then resting on the shoulder 9, and the bit being thereby suspended. The upper end of the hammer has a water conduit 16, extending down and diverging out each way forming side ports 17, which are above the stuffing box 4:, when the device is in operation, but when the bit is suspended, as above explained, the fluid pressure from' above will force the hammer downwardly until these orts are in osition,
to discharge water into the barrel 1, eneath the stuffing box 4, and the water then passes on down through the spider 7, and through the conduit 18, through the shank 10 and is discharged onto the blades of the bit and washes away the cuttings thereof and returns, laden with said cuttings,-up through the bore on the outside of the stem.
What I claim is:
. 1. In a device of the character described, the combination with a drill stem, of a drilling tool attached to the lower end thereof, and including a. barrel, a bit formed with a shank which has a bearing in one end of the barrel, a hammer mounted for reciprocation in the barrel and adapted to be driven against the'work by fluid impulses, exerted through the stem in successive strokes against the shank of the bit, and a yieldable member connected to the hammer and normally operating in opposition to the fluid pressure exerted against said stem.
,2. The combination with a drill stem, of a drilling tool, connected to the lower end thereof and including a barrel, a hammer therein, yieldable seat whereon the hammer is mounted, a bit formed with a shank which is movable lengthwise in a bearing carried by the lower end of the barrel, said hammer being adapted to be actuated with successive strokes against the bit, by fluid impulses exerted through the stem.
which is keyed against rotation relative thereto, said hammer being adapted to be actuated with successive strokes againstthe bit, by fluid impulses exerted through the stem.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WALTER LEE CHURCH.
