This invention relates to tools and more parthis depressed portion 7 in each member of the ticularly to jar cap wrenches. wrench it will be seen that not only the jaws and One of the objects of the invention is to prohandles are in the same plane but that the memvide a new and improved jar cap wrench. bers so formed are reversible, that is, the wrench Another object of the invention is to provide is constructed by pivotally connecting one side of 5 a jar cap wrench having new and improved gripone member to the corresponding side of the ping qualities and one which will grip a jar cap other member, consequently the members 1 and or the glass part ofthe jar without defacing the 2 may be made from the same die thus enabling same. a suitable wrench to be produced at low cost.

10 Another object of the invention is to provide a Gripping jaws are also provided in the smaller 10 plier like jar cap wrench which is efficient for the curved portion 1l of the S-shaped members the purpose, of simple construction and one which concavely shaped edges 12 of which are also promay be produced at low cost. vided with serrations so as to obtain a good grip- These objects and the several novel features ping surface.

The outer edges of the handles are tained is shown in the accompanying drawing in preferably provided with a flange portion 15 whichrounded as at 16 to provide a comfortable grip 20 Fig. 1 is a view shown in elevation of my imfor the hand as shown in Fig. 4. This grip may 20 proved wrench. be inexpensively formed on the edges of the Fig. 2 is a view shown inl elevation of another handles by rolling the edges thereof. form of my impovedwrench embodying features Referring now to Figs'. 2, 5 and 6, in this form of my invention. of my invention the S-shaped members 20 and Fig. 3 is a view in cross section taken on line 21 may also be formed in the same manner as 25 3-3 of Fig. 1. those in Fig. 1, that is as duplicates, the face of Fig.l 4 is a view in cross section taken on line one member being pivoted to the corresponding 4-4 of Fig. 1. face of the other member to form the wrench.

By providing jaws and the handles fall in the same plane 55 which is desirable, and that the members may be duplicates and consequently be formed from the same die at low cost. In addition it will be seen that I have provided a wrench the clamping jaws o! which are faced with yieldable gripping members providing new and improved gripping qualities in a wrench and grips which will not deface the article gripped, and which grips better due to the resiliency of the rubber gripping surface.

Having thus fully described my invention, its utilityand mode of operation.. what I claim and desire to secure by Letters Patent of the United States is- A jar cover wrench comprising two sheet metal members of S-shaped form having the bodies thereof oil'set in the mid portions in respectively opposite directions and pivoted together centrally of the offset portions, said members on one side of the pivot and at an end thereof having terminal handle portions and adjacent the pivot having similarly outcurved portions, the inner faces of which are serrated, the members on the opposite side of the pivot being outcurved on a greater radius than the portions of the first mentioned outcurved portions, the opposite faces thereof being serrated and--each terminal handle portion being T-shaped in lcross section with the cross member of the T-shaped portion extending along the outer edge of each terminal handle portion.
