JAMES A. WILcoX, 0F nocKY HILL, yA ssienon To nIMsnLr AND WAL TER s. WILcoX. or HARTFORD, CONNECTICUT.
Letters .Patent No. 104,913, dated Jane 28, 1870.
To all whom it may concern Beit known that I, JAMES A. Wmcox, of Rocky Hill, in the county of Hartfordand State .of Connecticut, have invented a new Improvement in Pipe-Wrenchj andI dovhereby declare the following, when, takeuin connection with the accompanying drawings and the letters of referencel marked thereon, to be a full, clear, and exact description otl the same, and which said drawingsl constitute part of this specification, andrepresent in Figure 1, a side view;
Figure'2, atop view; and in Figure 3, a'central section. This invention relates to animprovementin the pipe-wrench, for which a patent was granted to me dated September 3, 1861; that is to say, the construction of a wrench to. turn pipes or other cylinders..
In my original patent, the slide or head, which bears againstthe'adjustable jaw', was -made a part of the spindle or rod, upon which the spring wasarranged to vforce the slide against thea-djustable jaw. In such construction the spiudiewas liable to be bent, sons to prevent the working of the slide, and, further, to. retain the. slide 'in position, a-longA bearing was necessary for the spindle, which -confined meto the employment of avery short spring, and, in the operation of theadjustable j aw, the tendency was to -lilt upon the slide; difficulties in the operationof myv wrench which the present invention is designed to overcome.
The invention consists- First, in forming an arm or projection upon the ad' jnstable jaw against which the slide bea-rs, and so that, in .the movement of the said jaw, the bearing of the said arm is downward upon the slide.
Second, the arrangement ota ixed spindle upon.-
the bar through the slide, 'sothat the slide will work on the said spindle, and so that the said; spindle-will support the spring which operates the said slide.
A is the 'bar ot' the wrench, extending so as to be attached to or form the handle','and provided at its end Ywith a jaw, c, as seen in Iigs. 1 and 3, the said jaw formed of hardened steel, aud attached to the bar so as to be removed for repairs or renewal.
B is an adjustable jaw, constructed so as to yoke over the har, and pivoted below the bar to a head O, thev said head 'being form'ed upon a screw, D, which passes through a lug, E, and receives an adjustingnut, F, by the turning of which'nut, the jaw .B is thrown from or drawn toward the jaw A, to adapt the wrench to articles of diiferent diameters;
G is a slide, arranged upon the back of the bai-"A4 a-nd constructed with trunnions dd, so as to bear against the jaw B. The said 'slide is supported on a spindle, f, so as to move freely thereon, the said spin'- ldie being ixed'hetween two lugs, l), on the bar A. lhe said slide Gis bored out a portion of' its length of a larger diameter than the spindle, so that a'spiral Aspring around the spindle will cxtendintothe slide and' bear against the shoulder formed by the enlarged diameter, thus 'giving a spring of considerable length for the opcrationof the slide.
As the trunnions on the slide are located nearly over the pivot of the jaw B, the raising of the jaw,
as to the position denoted in broken lines, tig, 1, wouldtend to=raise the slide. To prevent this, `I .form arms I on the slide, as seen in Iig. 1, constructed so as vto beardownward upon the trunnions as the lever is raised, and as denoted by the broken lines in iig. 1. This relieves the spindle and vslide from the strain which -would otherwise be brought thereon by the op- 4 erationof the jaw B, and the spindle being immova' n ble vand suppoitedat'its two extremes, Vis not liable' to f injury from use, as is the case when the spindle is made a part-'of the slide and moves through bearings on the bar, as in my original patent.
The jaw end of the bar A is enlargedso as to form Aa. shoulder, ln., to prevent the jaw B from falling down over tlie'end of the bar.
I claim-as my invention- 1.; The arms I formedupon the jaw B,'so as to'operate upon theV slide G in the manner described.
2. In combination with the djustible jaw B, and fixed jaw on the bar A, the slide Garranged upon the fixed spindle f, and so as to bear upon the said jaw B, substantially as described.
