 COES D. THE COLLINS CO, 907 �formed at right angles to the Une of motion of the movable jaw, in the shank of aCoes wreiich, for relieving the handle froin the back strain of the rosette serew, substantially as describecl. (3) The combination of two or more par- allel grooves, d, iu the shank, A, with two or more corresponding projections, e, on the rosette, D, the same net being spiral, but running at right angles to the Une of motion of the jaw, substantially as described." �There was only one claim in the original patent, as folio ws : �" The combination of the parallel grove, d, d, d, in the shank, A, with the corresponding projections, e, e, e, on the rosette, D, the same not being spiral, but running at right angles to the Une of motion of the jaw, thus relieving the ferrule from all strain, while retaining the rosette in the same relative posi- tion as respects the handle of the wrench, substantially as and for the pur- poses set forth." �The defendant's wrench which is alleged to infringe claim 1 of the reissue is made in accordance with the description in letters pat- ent No. 50,364, granted to Jordan & Smith, October 10, 1865, for an "improved wrench." �The plaintiff's wrench and the defendant's wrench both of them con- tain improvements engrafted upon the form of wrench shown in let- ters patent No. 2,054, granted to Loring Coes, the plaintiff, April 16, 1841, for an "improvement in the method of constructing screw wrenches," and reissued to him, No. 139, June 26, 1849, for an "im- provement in screw wrenches." The main feature of the Coes wrench of 1841 was the moving of the adjustable jaw, by a screw placed at the side of, and parallel with, the main bar, which carried the permanent jaw at one end of it and the handle at the other end, the screw taking into an attachment to the adjustable jaw, and working that jaw to and fro without itself moving other- wise than by rotation, and having on its end furthest from the fixed jaw a rosette or milled head, which never approached to nor receded from the fixed jaw, and could therefore be rotated, 80 as to rotate the screw, by the thumb of the hand which held the wrench, because the rosette always retained the same position relatively to the handle of the wrench. A wooden handle was slipped over the handle end of the main bar, and a screw nut on that end bearing against the adjacent end of the wooden handle held the other end of the wooden handle against a ferrule and that against an iron plate and that against a shoulder on the main bar. The iron plate projected out on the same side with the rosette and next that face of it furthest from the fixed jaw. The plate carried the revolving end of the screw, the bearing point projecting beyond the face of the ro- ��� �
