Opinion

SHIPMAN, Circuit Judge.

The questions upon this appeal are in regard to the validity and infringement of claim 1 of letters patent No. [776]*776427,220, dated May 6, 1890, to William A. Bernard, for an improvement in pliers. The circuit court for the district of Connecticut found in favor of the complainant, which is the present owner of the patent, upon each issue. The inventor said in his specification that his object was “to provide an unobstructed-opening through between the parallel jaws for the passage of a rod, wire, or tool, and to adapt sheet-metal handles to the jaws in such a manner that the power will be applied equally at both sides of the jaws, to insure the proper strength and uniformity of movement.” Henry B. Russell, in letters patent No. 188,262, dated March 13,1877, and Chester W. Sykes, in letters patent No. 21,525, dated September 14, 1858, had shown pliers with parallel jaws, Each device contained a single pair of lever-handles inside of the jaws, and the handles and jaws in each device were connected in the middle of the length of the jaws so that the bearing for the handles was very narrow. The Bernard device has “double X lever-handles upon the exterior of the jaws, whereby an open space is left between such, jaws, the jaws being inclosed with the lever”; and there is a broad bearing surface upon the jaws, which are. enabled to grasp firmly the rod to be held. The patent to Peter Broadbrooks, No. 329,133, dated October 27,1885, was simply for cutting nippers, which consisted of two levers pivoted to each other, the jaw ends of the lever being integral with the handles, and a recess between the sides of the levers through which the wire which is to be cut can be passed. Neither patent is an anticipation of the Bernard invention, which was a decided advance upon Sykes and Russell, because the rod or wire to be gripped could be passed between the jaws throughout their length, and held with a firm grip, The means by which this was accomplished were inventive in their character. The two claims' are as follows:

(1) The combination, with the solid jaws, f, f', of the lever-handles, a, a', b, b', of sheet metal, bent v. to form hollow hand portions, the parts, a’, b', being flat, or nearly so, and crossing each other at opposite sides of the jaws, and connected by the pivot, d, substantially as set forth.
(2) The combination, with the parallel jaws, f, f', of the lever-handles, a, a', b, b', of sheet metal, bent v. to form hollow hand portions, the parts, a', b', being flat, or nearly so, and crossing each other at opposite sides of the jaws, the pivotal rivets, d, d, in line with each other, the rivets, e, passing through the respective parts, a', b', and the jaws and rivets, 3, passing through the metal of the handles and through slots in the jaws, substantially as set forth.
