A TTORNEYJ PATENT OFFICE.
REDUS D. DODDS, 0F HOUSTON, TEXAS.
SAMPLE-TAKIN G DEVICE.
Specification of Letters Patent.
Patented Jan. 4, 1921.
Application led November 14, 1919. Serial No. 338,133.
T 0 all whom t may concern.'
BeI it known that I, REDUs D. DoDDs, a citizen of the United States, residinfy at Houston, in the county of Harris and tate of Texas, have invented certain new and useful Improvements in Sample-Taking Devices, of which the following is a specification.
This invention relates to new and useful improvements in a sample taking device.
One obj ect of the invention is to provide a device of the character described, whereby samples of the strata being pierced, in the process of drilling wells, may be taken;
Another' object of the invention. is to provide a sample taking device, which is simple in construction and effective in removing samples of formation from the bore at any de th.
Vith the above and other objects in view, the invention has particular` relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification, and illustrated in the accompanying drawings wherein Figure l, is a vertical sectional-view of the device shown in position to begin the operation of taking a sample', and
Fig. 2, shows a vertical sectional view of the device after the sample has been taken and is ready to be withdrawn from the bore.
Referring now more particularly to the drawings wherein like numerals of reference designates similar parts in each of the fig-l ures, the numeral l designates a tubular section adapted to be attached to the 'lower end of the ordinary drill stem (not. shown). To
the lower end of this section a core barrel 2 is attached by means of the coupling 3, said barrel having its lower end serrated to readily penetrate the formation. The lower end of this barrel is notched as at 4, to permit the outlet of water from within the pipe to' keep the lower end of the barrel cool while the core is being formed. Near the lower end of the section 1, it has the perforations 5, 5 which are opened and closed by means of the valves 6, 6, pivoted to the lower ends of the respective arms 7, 7. These arms have bearings in and are pivoted to the annular member 8, which is xed within the section l and which is provided with the Water courses 9, 9.
apart, so as to hold the valves 6, seat-ed in` The lower ends of the arms 7, 7, are held down into the bore and rotated.
the perforations 5, by means of the coil spring 10, which is interposed between said ends .of said arms. The upper ends of the arms are outwardly curved for a purpose to be hereinafter stated.`
lVhen it is desired to take a. sample the barrel 2 is attached and the device is let lVater is forced under pressure down through the drlll stem and passes through the water courses 9, and through the notch 4, on to the cutting points of the barrel and passes thence upon the outside of 'the sectionl, and the drill stem to the surface of the ground. lVhen the core is formed and it is desired to sever the same, a weight 1l isdropped down into the stem and wedges between the, outwardly curved upper ends of the arms 7, 7 forcing them apart and unseatingthe valves 6, 6, thus permitting the water to pass from within thesection l, out through said perfor-ations 5 and up. The stemis then rapidly rotated and, the water course being cut off, the fric- `tion of the barrel against the formation causes the lower edge thereof to .become vheated causing the same to crimp inwardly and engage with the sample 12 of the formation within the barrel. Thev device is then withdrawn from the bore, carrying the sample with it and the water in the stem will drain out through the perforations 5, 5 without mingling with the sample or washing the same out of the barrel.
What I claim is:
l. A sample taking device, including a tubular section, whose lower end is provided with a perforation, a valve normally closing said perforation, a core barrel attached to the lower end of said section and means for lwithdrawing and holding said valve out of said perforation.
2. A sample taking device including a tubular section, provided with a plurality of openings, a core barrel attached to the lower end of said section, valves controlling said openings, pivotally mounted arms attached to said valves, and means adapted to be interposed between said arms to withdraw said valves from their corresponding openlnfrs.
l. A sample taking device including atubular section, whose lower end is provided with a plurality of openings, a core barrel attached to the lower end of said section, a plurality of arms pivotally mounted within said section, valves attached to the lower ends of said arms and cont-rolling said openings, a yieldable member interposed be tween said arms and operating to normally hold said valves seated in said openings and a member adapted to be interposed between said arms to unseat said valves.
4. A sample taking'l device including a tubular section whose lower end -is provided with a perforation, a valve normally closing said perforation, a core barrel attached lto the lower end of said section whose lower end is serrated and provided with an outlet opening and means for holding said valve open.
5. A sample takingr device, including a tubular section, whose lower end is provided with a perforation, a valve normally closing said perforation, a core barrel attached to the lower end of said section and Whose lower end is adapted to out into the formation to form a core, means for holding said valve open to divert the water from the lower end of said. core barrel thereby causing said lower end to be heated by friction with the result that said lower end'is crimped inwardly to sever the core.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
