SPECIFICATION forming part of Letters Patent No. 583,892, dated June 8, 1897.

Application filed January 19, 1897. Serial No. 619,728. (No model.)

To all whom it may concern:

Be it known that I, RICHARD H. DANIELS, a citizen of the United States, residing at Macon, in the county of Bibb and State of Georgia, have invented certain new and use f ul Improvements in Combinationrenches; and I d hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in combination-tools, the object being to provide acombined pipe wrench, cutter, and threader.

My invention consists of a tool having two movable jaws to clamp about a pipe and serve as a wrench and a combined die-stock and cutter adapted to be clamped by and coacting with said jaws.

My invention also consists of certain novel constructions, combinations, and arrangements of parts, as will. be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of the wrench portion of the tool. Fig. 2 is a bottom plan view of the same. Fig. 3 is also a top plan view showing the pi pe-cutter applied to the wrench portion. Fig. at is a side elevation of the same, showing the jaws of the wrench in section. Fig. 5 is a perspective view of the screw-threading die. Fig. i3 is a perspective view of the wedge-block. Figs. 7, 8, and 9 are views of a modified form of stock and thread-cutter.

The wrench portion of the tool comprises a handle A, having at one end a rigid jaw B, integral therewith and provided with an independent movable jaw 13, pivoted at a. The meeting faces I) b of the jaws, at the outer end thereof, are serrated in order to tightly grip a pipe. Between said jaws and the pivoted point the jaws are each formed with a semioval cut-away c, which together form an oval opening for reception of a pipe to be clamped. The serrated faces I) b are intended for gripping small pipes, while the said circular opening is for large pipes. The outer edge cl of the fixed jaw on its upper side and the outer edge d of the movable jaw on its under side are beveled. A stay-bolt c has its inner end pivoted at c to the said fixed jaw and its outer end threaded and movable through a guide-block f on the said pivoted jaw, and a set-screw f on the said threaded end is provided to adjust and hold the jaws tightly clamped about a pipe.

Thecutting and die stock is shown in Figs. 3 and 4E and consists of a body or pipe-chainber G, having at one side thereof an opening and a laterally-projecting guideway 9, leading therefrom and provided with two vertical side walls and a vertical end wall. The bottom of the guideway adjoining the bodywall has a slot 9', and below the guideway is an arm It, provided with a set-screw h, which projects from said body-wall. On the opposite side of the body-wall are two projecting arms '5 1 the upper or first-named having a set-screw 1 A sliding tool-carrier block his in the ver tical guideway g and is moved by means of an adjusting-screw k, which has bearing in the end wall of said guideway. In Fig. 4 an ordinary form of pipe-cutting disk or wheel j is carried by this tool-blocl;, but the threadcutting die 3' will be substituted therefor when it is desired to screw-thread a pipe end. A confining-plate Z- bridges across the front of the guideway and confines the tool-carrier therein. The plate is secured to the guideway-walls by screws Z.

In applying the stock to the wrench portion the jaws of the latter are opened and clamped about; the body portion G, as shown in Fig. 4, wherein the movable jaw B occupies the slot g and is clamped by the setscrew it, while the fixed arm B has position between the two arms '5 i and is clamped by the set-screw The pipe which is to be cut or threaded is first clamped in a vise and then the tool is applied. The cuttendisk or threading-die is forced against the pipe and the tool operated like an ordinary pipe cutter or threader.

Fig. 2 shows the reverse side of the wrench portion, provided with a diamond-shaped clamping-guide M, which constitutes apart of the cutting-cit tool, and N is a curved wedge-block to fill the space between the small diamond clampingguides and the inner wall of the body portion G. The oval form of the clamping-opening of the wrench is of great importance, for the reason that when clamping a powerful rolling grip is obtained which does not crush the pipe. The curved wedge-block fills the open space between a circular instrument inserted in the oval clamping-opening and the jaws thereof.

In the modification shown in Figs. 7, 8, and 9 the body Bhas an annular die-chamber 0, provided with two oppositely-disposed guideways 0 for the dies 1). A lug or pin 0 in each guideway is threaded at its upper end and projects through an opening 13 in the die. A nut 0 fitting on the threaded end of the pin, immovably confines the dies.

Guide-collars K are provided to fit within the body B when a small pipe is being operated upon. A side and an end view of one of these collars is shown in Fig. 9. Each collar has a threaded opening q, with which a screw q on the stock engages.

Myinvention provides a simple and effective form of combination-tool, which may be employed for a variety of purposes.

I do not limit my invention to the precise construction which I have shown in the accompanying drawings merely for illustration.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a combination tool, a handle and wrench portion comprising a handle having at one end thereof a fixed jaw, a movable jaw pivoted to the handle and coacting with the fixed jaw, said two jaws having terminal serrated clamping-faees adapted for small pipes, and between the same and said pivot an opening adapted to receive the body of a pipe cutting or die stock, and means for adjusting the jaws, substantially as described.

2. In a combination tool, a handle and Wrench portion comprising a handle having at one end thereof a fixed jaw, a movable jaw pivoted to the handle and coacting with the fixed jaws, said two j awshaving terminal serrated clampingfaces and adapted for small pipes, and between the same and said pivot an opening adapted to receive the body of a pipe cutting or die stock, a stay-bolt pivoted at one end to the said fixed jaw and having a threaded end movable through a guide on the pivoted jaw, and a confining-nut on the said threaded end, substantially as described.
