COMBINED PIPE WRENCH AND CUTTER.

SPEGIFIGATIONforming part of Letters Patent No. 508,077, dated November 7, 1893.

Application filed June 16, l 893. Serial No. 477,871. (No model.)

To all whom it may concern.-

Be it known that I, TILLMAN H. ANDERSON,

a citizen of the United States, residing at Spen-.

cer, in the county of Owen and State of Indiana, have invented certain new and useful Improvements in a Combined Pipe Wrench and Cutter; and I do declare the following to be a full, clear, and exact description of the wrench and cutter; and its objects are hereinafter more fully described.

I attain the ends by the mechanism illustrated in the accompanying .drawings, in which- Figure 1 represents a side elevation of a wrench'constructed according to the principles of my invention. Fig.2 is a central,longitudinal section of the same. Fig. 3 is a transverse, sectional elevation of the pivoted jaw on the line 11 of Fig. 2. Fig.4 is a detail end view of said jawshowing the position of the parts when the cutter is in use; and Fig. 5, is a similar view showing the cutter not in use.

The same designations indicate corresponding parts in the several views.

A represents the handle of an angular headed wrench B, provided on its upper face with a series of teeth S, and on the adjacent face thereto, with a gage W. A jaw 0 slides on said wrench coaxially therewith and is provided with integral bearings E wherein the jaw G is pivotally suspended by pin F. The jaw G is provided at its rear end with a dentated are T adapted to mesh with the teeth S of the wrench, whereby the altitude of said jaw is varied. The forward end of the jaw G is rigidly held in the casing D which is variably adjustable thereto by means of the wing screw I and spring J, slots cut in the sides of the casing D serving to permit its vibration on the termini of the pin V. The

upper end of the jaw G is recessed to accommodate the motions of the cutter U in its respective positions of utility and inutility; and the sides of the slot so formed are serrated at H to grasp the pipe. From the inner ends of the casing D curved arms K, dentated at L, project adapted to pass through slots formed in a projection X on the jaw O, engaging thus the spring-impelled arms N therein; release of said engagement being procured by impelling downwardly the lugs M on said arms.

The cutter U is mounted on a pin Q capable of motion in the angular slot 0 P in the jaw G, whereby the cutter will alternately be brought into and out of contact with the pipe. In either position the pin Q is rigidly held by the cam screw R located ad jaccntly thereto and revoluble like an ordinary screw.

It will be apparent that upon releasing the arms K and N from contact, by depressing the lugs M, that the jaw G will assume the position indicated in dotted lines in Fig. 1, during which time-and no other-its altitude on the wrench B can be regulated by reading of the diameter of the pipe, to be worked, in the gage W.

Having thus fully described my improvements, what I claim is In a wrench, the angular head B integrally formed with the dentated handle A provided with a gage W, in combination with the sliding jaw 0 provided with bearings E; the dentated jaw G pivotally suspended by pin F and provided at its rear end with a dentated are T registering with the teeth on handle A; the cutter U located in a recess of jaw G and adjustable therein so as to be brought a'nd maintained in contact with the pipe at will; the spring-controlled wing screw I to vary the angle of jaw G to the pipe; and the springimpelled arms N, provided with lugs M, adapted to lock the toothed arms K of the jaw G,-

in position, as set forth and for the purpose described. 1

In testimony whereof I affix my signature in presence of two witnesses.
