OASING-SWAGE,

Specification of Letters Patent.

Patented Dec. 2?, 191%.

Application filed December 18, 1909. Serial 2:10. 533,897.

To all whom it may concern:

Be it known that I, RYLAND W. Ensues, a citizen of the United States, residing at Vale, in the county of Malheur and State of Oregon, have invented new and useful Imrovements in Casing-Swages, of which the following is a specification. The invention relates to an improved caslng swage, being more particularly directed to an implement adapted to be adjusted within the casing tube or pipe section and operated to correct any surface indentation or irregularity in said section.

The main object of present invention is the provision of a sii 'age embodying separable sections and including with said sections a mechanism whereby the sections may be separated at the will of thehoperator to bear with practically any desired force upon the interiorsurface of the casing of the section, the formation of the swage sections being such that in size they will force the material of the casing against which they bear;

into the normal plane of the casing thereby obliterating any indentations or other irregularities in the' casing wall and in effect reforming said casing to provide a true cylindrical interior form. I j

The invention in its preferred detailsggf construction will be described in the following specification, reference being had particularly to the accompanying drawings, in' which: Figure 1 is n side elevation of the im proved swage. Fig. 2 is an end view of the same. Fig. 3 is a broken vertical section, artly in elevation. Fig. 4 is a reduced view illustrating the use of theswage.

Referring particularly to the accompanying drawings, the improved swage is made up of two members 1 and 2, the former of which will be hereinafter termed the base member and the latter the anvil member. The base. member is of approximately cylindrical form and of a thickness in accordance with the material to be operated upon. The exterior surface of the base is, for the greater portion ofits length, disposed at right angles to' its plane of movement,providing a bearing surface 3, while the ends beyond said bearing surfaces incline inwardly, as at 4, whereby to provide for theeasy introduction of the implement into the casing. The anvil member 2 is preferably of greater thickness than the base member and of less circumferential extent, the rurvatiuc of the outer or bearing surface of said anvil mem' ber being preferably on a smaller radius than the curvature of the base member. Theexterior surface of the anvil 1neinber;,cor1esponds to the similar surface of the base member, being formed to provide a central bearing surface 5 arranged oppos'itethe hearing surface of the base member and inwardly inclined end 6. The anvil member is-centrally provided with aradially arranged tubular projection-7 i nteriorly threaded at 8, while the baseniember is formed with a similar radia lg/proj rior bore l0/ The projections 7 and 9 are braced from the respective members by the usualwebs 11, so that a strong and substantial structure is provided.

B'otatably tll'itlllg fl in the bore 10 of the base member projection is an operating rod 192 terminally threaded at 13- to coliperate with the threadsS in the bore of the projection 7 A worm gear 14 is secured upon the "rod 12 in any preferred manner,

as for example by means of a Set screw 15. The gear is thus disposed between the proximate of the projections 7 and 9 so that when the parts are in collapsed or inoperative positions the inner ends of the projections Will bear against opposing surfaces of the gear. Mounted in spaced cars 16 projecting from the base member adjacent one edge of the cylindrical portion thereof is a shaft 17 on which intermediate the ears is formed a worm screw 18. The parts are so arranged and ofsuch relative sizes that the thread on the worm screw will engage the teeth on the gear 14 and rotate the latter in the revolution of the shaft 17. The shaft 17, which may be of any desired length, is terminally ection 9 having an inteends provided with an operating handle or crank 19.

In use, assuming that the swage is to be put in service to obliterate an indentation, as 20, in a casing tube, as 21, the parts are withdrawn to operative position that is the shaft 17 is operated so that through the medium of the threaded connection of the rod-12 and The operation is continued until the pressure t ial. extent is sutiieient to cause the anvil member to force outwardly the material forming the indentatien, thereby dbiiterating the same and restoring the normal form of the c: sing.

It is obvious, of course, that any irregw larity in the interior surface of the casing, other than a fracture, can quiekiy obliterated by the proper appiication 0f the swage. The impien'ient i s te be made in any r lesired size and the plane oi. the curvature of the respective base and anvii members 'Wiii be varied to suit different requirements.

Having thus described the invention, What is claimed as new, is

l. A swag'e including auanvii member, a base member hz-rvinga greater circumferenthan the anvil member, anoperating rod having threaded engagement with one of said members, a gear secured upon the red and means for v An interior swaging implement com? prising a base member, an anvil member, an operating rod having threaded connection with one of said members, a gear mounted upon the rod, a worm screw base member and cooperating with the gear, and a shaft coiiperating with the worm screw.

In testimony whereof-I aiiix in presence of two witnesses.
