Specification of Letters Patent.

Pateltctl Feb. 13, 1917.

Application filed October 23, 1915. Serial No. 57,560.

To all whom, it may concern:

Be it known that I, Gnovnn C. Snnw, a citizen of the United States, residing at Vest Brownsville, in the county of \Vashington and State of Pennsylvania, have invented certain new and useful Improvements in Tools, of which the following is a specification.

My invention relates to a tool, and more particularly to that type of tool designated. as a wrench, in combination with other fea tures.

It is one of the objects of the present in vention to provide :1. tool of the above-mentioned character, which not only includes monkeywrench jaws but also includes pivoted jaws adapted to engage rounded sun.

faces such. pipes and the like.

Another object resides in providii'ig a plurality of pairs of jaws all of which are regulated or adjusted by a single adjusting means. i

A further object resides in providing a stamped sheet metal handle, inclosing and supporting the adjusting means, as well as supporting the reinforcing and removable jaws.

A still further object consists in the pro Vision of a pair of pivoted aws having connection with a longitudinally movable memher for adjustment and each jaw engaging a pin for directing the movement of the jaws relative to each other to an open or to a closed position.

Other objects will be apparent from the following description, which is to be considered in connection with the accompanying drawing forming a part of the specifi cation, and in which I have illustrated a wrench constructed according to my invention and which I" rave found in practice to give good results.

In the drawing:

Figure 1 is a side elevation of the wrench.

Fig. 2 is a similar view, but with the handle broken away to disclose the details of the jaw-adjusting means.

Fig. 2' is a plan view ol' the sheet metal handle blanked out bclore swaging the same to shape, and

Fig. 4. is a sectional view on the line 4-4 of Fig. 1.

In detail: the tool comprises the handle 1 which is preferably stamped out of sheet metal in the form shown in Fig. 3 and punched as shown, the said sides A and B then being bent together in U-shaped relation alon the dot-at d-dash lines indicat ing such ending.

To close the open side of said handle 1 a.

fixed jaw 2 carries a base member 3, which base member is secure(. within the open side by means of rivets 4 and forms a closure therefor, as well as a mpporting means for said jaw on the handle. The back of the jaw 2 is extended and forms a guide forthe shank 5 of a movable coat-ting jaw 6. The jaw (3 may also be exended at the rear to form a lltLlIllTlGl head 'i and nail extractor'S and formed in alinemmt with the shank 5 is a screw driver 9. The inner cud of the shank 5 carries a tl readcd extension 10 which, between its ends, engages the adjusting nut 11 which is free to rotate and has its periphery cxzending through the sidesA and B of the handle 1 so that the said nut 11. may be tinned to adjust the po sition of the movable jaw 6.

Also the inner end of the shank 10 is threaded into one end f a link connection 12 which is connected at the other end to the pivot pin 13 of a pair of pivoted jaws 1 1 and 15. Said jaws are car. had by the said pivot pin 13 and each is P1O\ ided with an inclined slot 16 for engagement with a pin 17 in the I andle 1, said pins and slots serving to guide the jaws let and to a closed or open position according to the adjustment. One of the jaws 15 may be prc vided with a serrated work engaging face 12 if desired for more clficiently gripping smooth, round surfaces.

By reason of the fa ct that the shank 10 connects with both sh ink 5 and the pivot pin 13 through the nu dium of the link 12, when the adjusting nut 11 is moved both the jaw 6 and the pivoted jaws 1 1 and 15 will be In oved, and thus the adjustment of either end cl the wrench, or rather, either pair of jaws may be varied to suit conditions.

To properly guide ihe pivot pin 13 and the said jaws .14 and l5 in their adjusting movement, the sides 01. the link 12 are raised as shown at 19 and project through and are guided in the openings 20 punched through the side portions A aid B of the handle. Thus as the nut is tui ncd the jaws 14 and 15 always move in the uame relative relation and are supported when inengagement with a piece of work by men as of the pins 17. and the portions 19 of the link engaging the handle 1.

From the foregoing it will be apparent that I have provided a novel construction of wrench, accomplishing the objects named in the preceding paragraphs of this specification, and providing a wrench which is of simple construction and so assembled as not to get out of order. It is however, to be noted that I do not limit myself to the specific construction herein illustrated and described, but, in practice, may resort to such practical. modifications and changes of design, as fall within the scope of the appended claims.

I claim 1. In a tool of the class described, a handle portion comprising a sheet of metal bent longitudinally into substantially Ushape .and having its side portions adjacent one end provided with longitudinally disposed slots, a base member connecting the ends of said side portions, pins connecting the extremities of said side portions and arranged in spaced relation, a link slidably mounted in said handle portion and extending at its sides into said slots, a pair of jaws pivotal] y connected at their inner ends to said link and protruding at their free ends beyond said handle portion, the said jaws having elongated slots inclosing said pins, and means for moving said link longitudinally of said handle portion.

2. In a tool of the class described, a handle portion formed of a' sheet of metal bent longitudinally into substantially U-shape and having its side portions provided with laterally a'lined longitudinally disposed slots, a link slidably arranged within said handle portion, raised portions on the opposite sides of said link engaged within said slots and being equal in width to the latter, jaws pivoted at their inner ends to said link, and means for sliding said link within said handle.

3. In a tool of the class described, a handle portion formed of a sheet of metal bent longitudinally into substantially U-shape and having each of its side portions provid 3d with a pair of apertures, one of said apertures on each of said sides being elongated and disposed longitudinally of said handle, a link slidably arranged-in said handle portion, raised portions on the opposite sides of said link engaged in said elongated slots, jaw members pivoted at-their inner ends to said link and rotruding from said handle, a threaded shdable shank in said handle connected at one end to said link, and a rotatable nut inclosing said shank and rotruding at its periphery through the others of said apertures.

In testimony whereof I afiix my signature.
