PATRICK H. FRY, OI WHEELING, WEST VIRGINIA, ASSIGHOR OI DRE-FOURTH T cnannas F.

won'rn, a:

': TOOL.

To all whom it ma'i concem:

Be it known t at I, PATRICK FRY, a citizen ofthe United States, residing at Wheeling, in the county of Ohio and State 5 of West Virginia, have invented certain new and useful Improvements in Wrecking Tools, of which the following is a specification.

This invention relates to tools, and .the

10 primary object of the present invention is round work, such as pipes, or on polygonalshaped work, the tool being particularly adaptable for use in oil fields and the like with oil-well rigging, and other equipment. A further object of the invention-is the provision of a novel wrench jaw associated with the tool, the wrench jaw being so shaped as to permit effective gripping of pipes and the like, and removably connected with the tool whereby the same may be removed when the gripping teeth become worn or mutilated, and replaced by a new jaw, the removability of the same also permitting different sized jaws to be associated with the tool for engaging different sizes of work.

A still further object of the invention is to provide an improved combination wrecking tool of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view. the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings forming a part of this specification, in which drawings:

Figure 1 is a pers' ective view 0 the improved wrecking too longitudinally extending shank 5.

Fig. 2 is an enlarged fragmentary side elevation of. the tool, showing the wrench face or jaw being removed therefrom;

Fig. 3 is an enlarged transverse "section taken on the line 33 of Fig. 2; and

. Fig. 4 is a detail perspective view of the improved wrench face or jaw.

efernng to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates the improved wrecking tool, which includes the shank 5 is preferably med of a good grade of metal, such as steel or the like, and can be either round or, as shown, polygonal shaped in cross-section. The upper or rear end of the shank is preferably flattened as at 6 to provide a head 7, the free edge of which can be sharpened to provide a penetrating edge 8. The formation of the head 7 permits the same to be used in connection with the shank 5 as a pinch-bar. The forward or inner end of the shank KELSEY, GEORGE E. MAHLSTEDT, AND ROY E. HOOK, ALL OF FORM.

The I 5 has formed thereon a rearwardly curved extension forming an inclined head 9, and a connecting transverse portion 10. The freeend of the head 9 has its inner edge beveled downwardly as at 11 and provided with a claw 12, so that the same may conveniently engage nails, spikes, or the like, which are to be extracted or pulled. The

outer surface of the head 9 and the connecting portion 10 is in the form of a semicircle so as to form a rocking fulcrum for the nail puller or claw 12. On the outer edge of the shank 5 adjacent to the inner or forward terminal thereof and directly in transverse alinement with the head 9 is formed a hammer head 13, which can be colpveniently used for driving nails and the li e.

The head '9 carryin the claw 12 is so disposed in relation to t e forward end of the shank 5 and the connecting transverse portion 10 as to form a rigid-jaw wrench, and

as shown in the drawings, a, removable jaw 14 can be associated with the head 9, the connecting portion 10, and the forward end of the shank 5.

This removable jaw 14 includes a substantially U-shaped body 15 forming sidewalls 16 and 17 and a connecting wall 18. The inner faces of the side walls 16 and 17 are disposed in angular relation to each other and gradually converge toward their inner ends and are provided with bitingteeth 19. These ortions form the active faces of the jaw. he outer surfaces of the side walls 16 and 17 and the connectin wall 18 are grooved as at 20 defining si e flanges 21. The inner edge of the head 9, the-connecting portion 10, and the forward end of the shank 5 are provided with ribs 22, which are. adapted to fit within the grooves 20. The ribs 22 and the flanges 21 can be rovided with alined openings 23 and 24, w ich can receive the removable retaining pins or the like 25. If desirable, these pins can be in the nature of screws or the like.

It is obvious that when the teeth 19 become worn on the active faces of the jaw, that the jaw can be removed and a new one substituted therefor. It is also obvious that different sized jaWs can be used for different sized work.

While as shown the jaw 14 has its active faces 19 arranged in converging relation, it is to be understood that the same may be formed in parallel relation for square or polygonal work if desired.

From the foregoing description, it can be seen that a, novel and simple tool hasbeen provided, embodying a pinch-bar, a nail extractor, a hammer, and a wrench.

Changes in details may be made without imam? departin from the spirit or scope of this inventiong lmt,

I claim:

1. A wrecking tool comprising a handle lever, a head formed on one end of the lever arranged to project rearwardly toward the opposite end in angular relation to the handle lever, guide and locking ribs formed on the inner surface of the head and said handle lever at the forward end thereof, a removable jaw associated with the head and handle lever including angularly I related slde walls, the outer surface of the side walls being rooved for the reception of said locking ri and defining guide and retaining flanges, and means extending through said flanges and ribs for holding the jaw a ainst movement in relation to the head an handle lever, the inner surfaces of the walls of said jaws being provided with toothed active work-engaging faces.

2. A tool of the class described comprising a handle, a U-shaped head at one end of the handle, one side wall of the head constituting a portion of the handle, upstanding ribs on the inner walls of the head, 1|. removable jaw for insertion in the head including angularly related side walls, and spaced flanges on the jaw to engage opposite faces of the ribs and having toothed active faces, and means extending through the flanges and ribs for retaining the jaw against movement in relation to the head and handles.
