SPECIFICATION forming part of Letters Patent No. 628,218, dated July 4, 18.99.
Application filed Octoberfll, 18 98. Serial No. 693,552. (No-model.)
To all whom t may concern.-
Be it known that we, ROBERT ASHWORTH and ALBERT W. AsHwoE'rH, citizens of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Wrenches, of which the following is a specificatiomreference being had therein to the accompanying drawings.
Our invention relates to wrenches having a pivoted jaw opposite a bearing-surface, and is mainly intended for wrenches intended to grasp a cylindrical body, as pipe-wrenches, although it is also adapted to be used as a nut-wrench; and the object of our invention is to produce asim ple and inexpensive wrench of that class with which objects of various sizes can be grasped equally well without changing the location of the fulcrums of the jaws, said wrench being provided with two jaws independently pivoted,V but mounted upon the same handle. We attain this object b y the construction illustrated in the accompanying drawings, in which-Y Figure lis a side View oi' a pipe-wrench constructed in accordance with our invention, the adjustable body of the outer jaw being shown substantially parallel with the handle and its gripping-face relatively close to the grippingface of the inner jaw. Fig. 2 is a longitudinal section of the pipe-wrench in which the adjustable body of the outer jaw is substantially at right angles with the handle and its gripping-face relatively distant from the gripping-face of the inner jaw, although the distance between the parts of the two jaws is the same in both' figures. Fig. 3 is a longitudinal section of a nut-wrench, showing our invention applied thereto by having the pivoted jaws slightly modified in form to grasp a polygonal object. Fig. l is a perspective view of the pipe-wrench shown also in Figs. 1 and 2. Fig. 5 is a transverse section on line a: x of Fig. l. Fig. 6 is a longitudinal section of a pipe-wrench constructed in accordance with our invention provided with a modified form of pivoted inner jaw. Fig. 7 .is a longitudinal' section of the wrench with the jaws transposed on the pivot-'pins to further increase the capability of the Wrench to grasp large objects.
In the drawings, A represents the handle of the implement, the inner end B of which is bentlaterally and is slotted lengthwise to obtain two iiat branches b, on the inner portion of which is pivoted to said branches upon the pivot-pin c the .body d of the longest or outer jaw` D. To the outer ends of said branches the inner jaw E is pivoted upon a milled-head pin f, which passes through said branches and has its `end screw-threaded for engagement with a screw-tapped hole in one of the branches. The pivot-pin cis similarly headed and screw-threaded. The body d of the outer jaw is preferably slightly tapering, wider at its inner end, to obtain the best form of abutment for the inner face or heel of the pivoted jaw E. The body d of the outer jaw D has aseries of perforations d2, either one of which is adapted to receive the pivot-pin c, so that the implement is capable of engagement with pipes or other bodies varying greatly in size. The jaw E has also a series of perforations e transversely thereof, all substantially at the same distance from the back or bearing face of said jaw, to also insure the capability of adjustment of theimplement.
When the device is intendedl for use as a pipe-wrench and it is desired to have an inner bearing-surface provided with a large number of interchangeable bearing-teeth, a wheel G may be substituted and pivoted upon the outer bearing-pin f; but if the implement is to be used as a pipe-cutter a cutting-wheel l may, as usual, be substituted for the wheel G. In Fig. 7 the location of the jaws is shown transposed and the latter reversed on the pivot-pins, in which position the capacity of the wrench to grasp large objects is further increased. In either position 0f the jaws the wrench is particularly well adapted to grasp and rotate pipes or other objects located alongside of Walls or in other limited locations.
If the implement is to be used as a nutwrench, the outer jaw "D is provided with a liat bearing-face and the inner jaw E is also provided with a flat bearing-face, as shown in Fig. 3.
Having now fully described our invention, we claim- 1. A Wrench consisting of a handle having its inner end bent laterally and forked, each tions, and two oppositely-disposed and transposable jaws pivotally mounted upon said pins, the body of one of said jwas having a series of pivotal perforations, snbstantiallyas described.
In testimony whereof We allx onr signattures in presence of two witnesses.
