Application filed April 5,

vide an improved wrench more especially for opening that class of cans, jars, bottles or the like, which have screw tops orcaps;

to provide such a wrench which shall be capable of, fitting a large range of sizes of such capsor tops, and engage them all firmly and securely; to enable the wrench to bequickly and easily applied to tops, or caps of various sizes, without any particular care or adjust ment; to secure such an arrangement-of the jaws for smaller tops or caps, with respect to the other. jaws, that they serve as a stop to engage the top or cap and position the wrench; to strengthen the jaws of the wrench so that they will not spring or twist out of their proper plane; to effect such strengthening by having the jaws for the smaller sizes-of tops or cap reenforce the, jaws for larger sizes, and to obtain'other results and advantages as may be brought out Referring to the accompanying drawings, in. which like numerals of reference indicate the same parts throughout the several views,

handles

That is to say, if the jaws are not symmetrically opposite but somewhat out of such relation as shown in full lines in Figure l, when applied to a top or cap, pressure upon the handles will automatically draw them into the desired opposite relation, as shown in dotted lines in said Figure 4-, without any particu lar attention or voluntary adj .stment by the operator. Preferably one of the chordal or ai'ixiliary jaw portions 6 is extended at the pivotal end of the wrench and shaped into a bottle opener 13, and the tree extremities of the

handles

Various detail modifications and changes can be made by those skilled in the art in the manufacture of our improved wrenches without departing from the spirit or scope of the invention, and we do not wish to be understood as limiting ourselves except required by the following claims when construed in the light of the prior art. I

' Having thus described the invention, what we claim is:

" 1. In a. wrench, the combination of gripping jaws pivotally connected at two of their adjacent ends and having handles at their other ends, said jaws comprising cooperating main portions oppositely bowed apart and chordal portions on said main portions offset from the plane thereof, all said portions having their oppositely adjacent edges adapted to grippingly engage an article.

2. In a wrench, the combination of gripping jaws pivotally connected at two of their adjacent ends and having handles at theirother ends, said jaws comprising cooperating main portions oppositely bowed apart and chordal portions secured at their ends thereto and spaced therefrom at their middle portions, all said portions having their oppositely adjacent edges adapted to grippingly engage an article.

. 3. In a wrench, the combination t gripping jawspivotally' connected at their adjacent ends and having handles at their other ends. said jaws each comprising spaced parallel portions having arcuate appositely adjacent edges to grippingly enan article, the oppositely adjacent arcuate edges in differentplanes being termed with ditlt'erent radii to grippingly engage articles of different sizes.

4. In. a wrench. the combination of gripping jaws 'iivotally connected at their adjacent ends and having handles at their other ends. each at said jaws comprising a main portion and an auxiliary portion semred to said main portion in spaced and substantially parallel relation there o and extending trons. the pointot nivotal'connection of said substantially to the handle. both said portions having their oppositely adjacent edges formed to grip an article.

5. In a wrench. the combination of gripping jaws pivotally connected. at their ad jacent ends and having handles at their other ends, said jaws comprising cooperatinain portions oppositely bowed apart and longitudinal reentorcing portions on said main portions, both said main portions and reentorcing portions having their op- }osite adjacent edges adapted to grippingly engage an article.

6. In a wrench, the combination of gripping jaws pivotally connected at their adjacent ends and having handles at their other ends, said jaws comprising cooperating main portions oppositely bowed apart and longitudinal reentorcing portions on said main portions ofi'set from the plane of the main portions. oppositely adjacent edges of said main portions and of said reenforcing portions being formed on difterent radii to grip an article.

7. In a wrench. the combination of gripping pivotally connected at their adjacent ends and having handles at their other ends, said jaws comprising cooperating portions with gripping edges oppositely bowed apart and longitudinal. re.- enforcingportions onsaid main portions offset from the plane of the main portions and having each a plurality of gripping arcs of different radii to engage articles of 4 different sizes THOMAS HARDING.
