SPECIFICATION forming part of Letters Patent No. 568,067, dated September 22, 1896.
'Application tied necemterze, 18'95. sentano. 573,358. ditmaal.)
- To @ZZ whom it may concern,.-
Ipo
Be it known that I, GEORGE H. FULLER, a citizen of the United States, residing at Gresham, in the county of York and State of Nebraska, have invented a new and useful Drill, of which the following is a specification. f
This invention relates to an improvement in drills for assisting in sinking or cleaning out oil-wells, Ate., and the object in l.view is j to provide a simple, inexpensive, and efficient Y equal to or greater than the external diameter of the pipe or tubing with which the well is lined.
A further object of the invention is to provide a boring-tool which may be used simply as a reamer or as a reaming attachment to an ordinary welldrill.
Other objects and advantages of the invention will appear in the course of the'subjoined description.
The invention consists in certain novel features and details of construction and arrange ment of parts, as hereinafter fully described, illustrated in the drawings, and finally pointed out in the claim.
In the accompanying drawings, Figure 1l is a vertical sectional view showing the application and use of the improved boring device. Fig. 2 is a detail perspective view of such device. Fig. 3 is a vertical longitudinal section through the same. t
Similar numerals of reference designate corresponding parts in the several figures of the drawings.
Referring to the drawings, l designates a tubular stock or bitof any desired length, the lower end of which is shaped` in` any suitable rnanner to constitute a drill-point 2, which may be tempered to adapt it to bore through hard substances. At its upper end the stock l is screwthreaded to adapt it to be secured to an operatingshaft 3 by means of a threaded sleeve or coupling 4 or in any other convenient manner.
5 designates a pair of bowed springs `arranged diametrically opposite on the stock l and secured iiXedly thereto at their upper ends by means of a rivet 6. The lower eX- tremities of these springsare riveted or otherwise secured to a slide collar or ring7, free `to slide longitudinally upon the tubular stock and provided at points diametrically opposite with longitudinal slots 8. A throughpin `9 extends transversely through the tubuspring, as regards the direction of rotation of l the tool, are sharpened or brought to a cutting edge, as indicated at 9, so that upon the rotation of the tool the expansive springs will ream out and enlarge the bore made by the drill. The central bore in the stock 1 opens out upon opposite sides of the stock adjacent to the drill-point, as indicated at l0, so that water forced through the tubular stock under pressure will enter the bore made by the drill and thoroughly flush the same y and bring the borings to the surface, Where they may be gotten rid of.
In operation, after starting the well, a section of pipe or tubing 1l is inserted until the bottom of the initial portion of the bore is reached, after which the-improved boring device is inserted into the upper end of said pipe, and by compressing the spring cutters 5 the said tool is forced downward until it passes out of the lower end of the pipe ll, whereupon the spring cutters 5 automatically expand into the position shown in Fig. 1. Upon now revolving the boring-tool the cutters 5 will reain the bore of the well to an 'extent equal to or greater than the diameter of the lining-pipe 1l, the drill-point 2,'of course,
traveling in advance of the spring cutters 5 and performing the initial boring. After advancing the boring device to a sufficient depth the pipe 1l is driven downward and an additional section placed behind it. In this inanner the Well may be bored and lined until IOO completed. The boring device may also be used withad'vantage to clean out a drilled well and loosen the dirt and sediment which may have collected in the bottom thereof. Upon drawing upward on the boring-tool the expansive cutters will be compressed by the lower end of the Vtubular lining l1, so that the said tool may be readily and entirely withdrawn from the Well.
It will be understood that the expansive cutters may be used either in connection with a drill, as illustrated in the drawings, or upon a plain bit without a drillpoint, in the latter oase being useful for 'cleaning purposes.
It will also be apparent that changes in the form, proportion, and ininor `details of construction may be resorted Ito Without departing from the spirit or ysacrificing any of vthe advantages of "this invention.
Having thus desoribed'the invention, what is lclaimed-"as new is- -Arboring device vfor Wells, 'consisting of a tubular stock made in one -piece and having one end hatten-ed from opposite sides to close the end of the lstock and 'forni ladrill-point and also provided at each side of the drillpoint with discharge-openings aiording conn-` rnunication between the bore of the stock and the hollows o f the drill-point, in combination with a `pair of bow-'shapedspring cutters permanently attached at their upper ends to the stock, a slide-collar mounted loosely on the stoek and having opposing longitudinal slots and also having the lower ends of the cutters permanently attached thereto, anda Itransverse stay-pin passing through the lower end of the stock and having its projecting ends arranged in the slots of the sliding collar, substantially as and yfor theripu-npose described.
In testimony `that 'I 'cla-iin "th'e io'regoiiig; as iny'own I hav-e hereto affixed niy'signat-u're'in the ,presenceoftwo witnesses. y ,Y y f v GEORGE EL IiUIfLER.
