wnmvcnj Specification of Letters Patent. Patented A11 1'7, 1920.
Application filed May 28, 1919. Serial 110.800.4 11.
To alZ whom it may concern: Be it known that we, Urn .mps Evrrs and Crmn'nns BnNNnn, citizens of the United States, residing at Benton ll arbor, in the county of lierrien and State of Michigan, have invented certain new and useful Tmprovements in lVrenches, of which. the fol.- lowing is a specification.
(lur invention relates to improvements in wrenches for use in turning or unscrewing round or cylindrical objects, as gas pipe, cy-
lindrical rods, &c., and its objects are: first,
to provide a strong, reliable wrench that may be readily adjusted, longitudinally, to operate perfectly upon any size of pipe; sec- 0nd, to provide a means whereby the adjustable jaw may be made longer than the space between the short arm and the long arm of the head of the wrench, and still may be readily applied to, or taken from the head of the wrench; third, to provide a means whereby the handle will be strengthened much beyond the strength of the adjusting rod or bar; fourth, to provide a means whereby the wrench may be readily assembled or taken apart, and, fifth, to provide a means whereby the grip of the wrench upon the object to be handled will be readily made perfect, and still may be readily released when the movement of the wrench is reversed.
lVe attain these objects by the mechanism and a1 'angeulent of parts shown in the accompanying drawing, in which Figure 1 is a side elevation of the wrench complete. Fig. 2 is a plan of the same. Fig. 3 is a longitudinal section of the wrench head and the lever strengthening element practically on the line 8, 3 of Fig. 1, looking relatively upward. Fig. 1 is an edge view of the adj ustable jaw removed from the wrench head, and Fig. 5 is a face view of the end of the head, shown in section upon the line 5-5 of Fig. 1.
Similar reference numerals indicate similar parts throughout the several views.
This wrench is made with a head having a long arm 1 which is formed at a right angle at the end to form a resistance wall or jaw to meet the pressure of the pipe or other article when being pressed heavily by the adjustable jaw 3. The wrench 1 also has a short arm 2 arranged to form a proper openarm and the right angled end of the arm 1,
mg or passage way between the end of this the two arms forming guideways or slideways for thcad ustable jaw 3. The right angled part of the arm 1 has a serrated, or
toothed insert (1. This insert is, preferably, made to wedge slightly into its bearing in the arm say of an inch, as indicated in Fig. 5, so it may be driven solidly into place without danger of being driven through its bearing, and we prefer that it be secured into placeby some safe means as, for instance, by a screw 16 inserted]practically as indicated in Fig. 1, though this is not an absolute necessity in the construction. The serrations or teeth on this insert should in cline toward the arm 1, as indicated, so as to insure the full strength of the arm 1 when operating the wrench.
The adjustable jaw 3 is fitted to slide freely, but snugly between the arms 1 and 2, and has an insertlmortised into one end, as indicated at 4,- and securely anchored in placed by means of a pin 5, or other suitable appliance so there is no possibility of the insert being moved or displaced in its bearings no matter what strain may be brought to bear upon it. lVe provide overlapping sides 7 and "2" for this jaw so attached that they will form a perfect slideway or guidmvay upon the arms 1. and 2, so the jaw cannot but move directly with said arms, or, rather, longitudinally thereof, when actuated by the actuating rod 11. For the purpose of providing as much space as possible we prefer that the side 7 be made i11- tegral with the jaw 33 and the side 7 be arranged to be secured to the jaw by means of screws, as 8, or other suitable appliance. The serrations or teeth upon the convex surface of the insert 1 should incline away from the arm 1 to correspond with the serrations on the insert 6, and for the same purpose.
F or the purpose of rendering the lever or handle of this wrench as strong as possible we apply a cylindrical arm or lever 10 by screwing it into the hub 9 of the head 12, or otherwise securely connect said lever and head. We then pass the actuating rod or bar 11 through this arm and pass the end into an opening in the back end of the adjustable jaw 8, where we secure it to revolve freely, and at the same time to push, or draw the jaw, by means of a pin 14 passed through the body of the jaw and engaging the adjusting rod by passing along one side of the collar or annular depression 13, be-
tween the body 11 and the head 15. The adjusting rod 11 is screw threaded near the inner end and is made to engage a corresponding screw threaded part of the jaw body, as at 11, so that if the rod or bar 11 is turned to the right, or to the left, the jaw 3 will be moved endwise accordingly.
The part 12 represents a handle on the adjusting bar 11 by means of which said bar may be readily revolved to the right, or to the left, as desired.
lVe greatly prefer to have the grip handle 10 project longitudinally over the sur face of the lever handle 10, as indicated in the sectional lines in Fig. 3, as, by this means We are able to produce two good results, namely: first, to cover the end of the rod 11 and thus protect it from the danger of becoming covered with oil, dust, &c., and, second, by this means the handle is greatly strengthened as the entire strain is not, thus,
made upon the end of the rod 11 as it would be with this rod exposed as in Figs. 1 and 2.
What we claim as new in the art is:
In a pipe wrench, a head having a long arm, the end of said arm formed at a right angle therewith forming a permanent aw, a short arm parallel with the long arm and integral therewith, a sliding jaw mounted between the two arms, a tubular arm securely connected with the head of the wrench and extending baclm'ardly therefrom opposite from the arms, a screw threaded bolt passing through said tubular arm and revolubly connected with the sliding jaw, and
a tubular guard upon the outer end of the threaded bolt and passing over the tubular arm as a guard.
