LANDON BATCI'ILOR, OF LAWRENCEBRG, INDIANA.

WELL-'TUBE Toor..

Application filed September 29, 1922.

T 0 all whom t may concern.' e

Be it known that l, LANDON BATGHLOR, a citizen of the United States, residing at Lawrenceburg, in the county of Dearborn and State of Indiana, have invented new and useful Improvements in fell-Tube Tools, of which the following is a specification.

My present invention has reference to a well tube tool.

My object is to produce a tool of this character which may be successfully employed for splitting, cutting and pulling deep well tubes.

A further object is to produce a tool of this character which shall be characteristic of simplicity in construction, cheapness in manufacture, coupled with ease and accuracy in operation.

The foregoing, and other objects which will present themselves as the nature ofthe invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this application.

In the drawings Figure 1 is a side elevation of a tool in accordance with this invention.

Figure 2 is a top plan view thereof.

Figure 3 is a sectional'view on the line 3 3 of Figure 2.

Figure 4L is a sectional view on the line et-4 of Figure l..

Figure 5 is a perspective View of the wedge member employed.

Figure 6 is a view of one of the cutting elements which may be employed.

Figure 7 is a view of one of thel puller elements which may be employed.

As disclosed by the drawings, my improved tool includes a body member 1 which is round in plan and which, at diametrically opposed points is provided with longitudinal openings 2 that communicate with its bore 3. The body 1 is provided with a central hub extension 4, the bore of which is in a line with the bore of the body, and the said hub is provided with exterior threads 5. Screwed in the hub is a tubular member 6. Locking means between the tube 6 and the hub may be provided. The tube 6 has its bore of two diameters, the inner bore thereof communicating with the bore of the hub and the bore of the body and Serial N'o. 591,372.

providing a shoulder 7 between the same and the smaller and outer bore. On the outer end of the tube 6 there is one member 8 that constitutes a raceway for anti-frictional elements 9, and the other member of the raceway is indicated by the numeral 10.

The wedge member comprises a body portion 11 and a threaded stem 12, which eX- tends from its reduced end. The body 11, upon its opposed faces has its diagonally opposed edges provided with longitudinally extending ribs 13 and le respectively. The body of the wedge 11 is designed to be received in the bore 3 of the head 2, the threaded stem 12 thereof passing through the bore of the hub and through the bore of the tubular member 6.

Designed to be received in the openings 3 are block members. As the body portion of all of the block members is of a similar construction, the same is indicated in the several figures of the drawings by the numeral 15. Each block member has its inner edge provided with an L-shaped slot 16 to receive the flanged edges 13 and 14 of the wedge 11, it being understood, of course( that the angle slots 16 of the opposed block members 15 are oppositely directed. Also the inner walls of these slots are arranged at angles corresponding to the angle outer edges of tite wedge member 11. Certain of the blocks 15 have their outer ends bifurcated in a line parallel with the longitudinal plane of the body 1, and in these bifurca tions there are received cutter wheels 16. These wheels are employed for splitting a tube. Other of the blocks 15 have their ends provided with transverse bifurcations to receive therein cutter wheels 17 which are disposed right angularly with respect to the longitudinal plane of the body 1. These cutter wheels are employed for cutting a tube transversely, while other of the blocks 15 have their outer ends beveled or wedge shaped, as at 18. These blocks are designed for pulling tubes.

The numeral 19 designates a rod member threaded at its outer end to be coupled to the operating rod or tube. The rod member for the major portion of its length is hollow, the threaded end thereof, however` being slotted, and in the bore 2O of the said rod member 19 there is received the threaded stem 12 of the wedge member 11. The rod member is provided with additional threads to those ou its outer end, and

on the last mentioned threads there is screwed a nut 21 and a lock nut 22. The lock nut is in contacting engagement with therace or cage element l for the antifrictiona-l balls 9, so that the rod 19 is freely revoluble in the tubular member (5. The rod has its inner end preferably integrally formed with a head 23 that has its bore provided with threads 24 to engage with the threaded stem l2 of the vwedge member 11.

On its opposed sides at points arranged right angularly with respect to the slidable blocks there is secured to the body l one end vof flat arched springs 25. These springs are designed to frictionally Contact with the bo-re of the tube or pipe to beoperated f on by the tool.

It is believed that the construction of the tool will be perfectly apparent to those skilled in the art to which such inventions relate, the operation being as follows:

The tool is let into the tube or pipev to be operated upon. The springs 25 frictionally engage the bore of the said tube or pipe, holding the body l against accidental or free movement therein. Theope-rating means connected with the rod 19 revolves the said rod which causes the interiorly threaded head 24 thereof, which coengages with the threaded stem 12 of the Wedge l1 to move the wedge longitudinally,

forcing the blocks l5 outwardly through the openings 2 in the body 1, causing the elements on the ends of the said blocks to either split, cut or tightly engage the tube or pipe for the pulling thereof.

Having described the invention, I claim l. In a well tube tool, a body which is round in plan having a. central boreA and diagonally opposed lateral openings comvmunieating with the bore, a hub o-n the outer face of the body-having a boreI in a line with the bore of the body, blocks slidable through openings formed in the body and having their outer ends provided with well tube engaging elements, each of said blocks having its inner end provided with a 'bayonet slot arranged at an inclination,

a fiat wedge mounted for slidable movement in the bore and having anglel shaped edges disposed in opposite directions and received in the slots of the blocks, said wedge having a threaded stem projecting through the "ein of the body, a. tubular extension on the hub, an operating rod having a bore at its lower end which threadedly receives the stem of the wedge, and` an antifrictional bearing means between the rod and the said tubular extension.

2. A well tube tool including` a bodyhaving a central bore and opposed openings communicating' with the bore, blocks slidable through the openings, and having well tube tool engaging elements on their outer ends, said blocks having their inner ends provided with angle slots, the inner walls of which being arranged at an inclination, a wedge member having its edges provided with diagonally opposed flanges disposed in opposite directions, said flanges being received in the angle slots of the blocks, a threaded stem on the wedge member passing through the bore of the body, said body having a tubular extension in which the stem is received, a rod having its lower end provided with a bore to threadedly receive the stem tlrerein, an antrifrictional bearing between the rod and the tubular extension,

and arched springs on the sides of the bodyL arranged right angularly With respect to the openings therein.

In testimony whereof I affix my signature.

` his LANDON BATCHLOR.
