Opinion

Bradley, Justice.

This case, though a small one, has given me a great deal of perplexity. The patent sued on is dated June 9, 1868, and antedated May 19, 1868, upon an application which was sworn to October 3, 1865, and filed in the patent-office February 19, 1866. The drawings and model were filed at the same time, the printed copy ‘ of the file-wrapper to the contrary being a misprint. The application was at first rejected on the second of March, 1866; but upon a Very slight alteration made in the claim, it was authorized to be issued in November, 1867, and was actually issued June 9, 1868.

The patent is for an improvement in handles for crosscut-saws, invented, as alleged, by Patrick Donoughe in 1864 or 1865. The improvement’ consists, as stated in the specification, in the combination and arrangement of a handle, ferrule, washer, screw-nut, and a shank furnished with an opening for the saw-blade, the whole constructed, arranged, and operating, as afterwards described, with references the drawings. The handle described is the ordinary upright wooden handle used on crosscut-saws. Into this handle is inserted from below, a rod constituting the shank, provided with a screw-thread, working in a nut fixed in the interior of the handle, so that by turning the handle the rod is drawn up into it, or forced out, at will. The lower end of this rod or shank has a long narrow slat for receiving the end [743] of the saw. When the saw is inserted in the shank, it is drawn! tightly up to the handle by turning the latter in the proper direction, > so as to draw the rod or shank np into the handle. To protect the , handle l'rom wear and abrasion when the saw is drawn tightly against it, its lower end is provided with an iron ferrule, and between the, handle and the saw is interposed an iron washer of the size of the; end of the handle, and having a hole in the center for the rod to pass, through. On its upper side this washer (when the saw is drawn, tightly to its place) is in contact with the ferrule; on its under side' it is in contact with the back of the saw. In order to prevent the> washer from dropping down out of place, away from the handle, when the saw is lowered for removal, or when the shank is lowered to, re-, ceive the saw, it (the washer) has a sleeve surrounding the hole in, the center, which projects upwards, inside of the ferrule, where it is, turned over or flanged out, so as to rest on a projection in the ferrule. The washer is thus loosely attached to the ferrule, and cannot drop away from it, although the ferrule may turn with the motion of the • handle without turning the washer. This arrangement is described.in the specification as follows: “The washer is placed in the ferrule,, b, and is set or bent down on the flange of the ferrule, as represented in Fig. 1, hut arranged so that it will turn in the ferrule with ease.” ■

One of the features of this handle is that the rod or shank does not; project above the handle, nor even pass through it, the upper end of, the rod being concealed in the interior of the handle, and the top of . the handle having the usual smooth and rounded appearance, so as not. to injure the hand of the workman. i

The claim of the patent is as follows: “What I claim as my invention is the arrangement of the handle, a-, ferrule, b, washer, c, rod, - d, and nut, e; the whole being constructed, arranged, and operating substantially as herein described, and for the purpose set forth.” In other words, the claim is for the whole concrete thing, with all its, parts, substantially as described. This is the form of the claim, and, in view of other saw handles previously patented, described, or in, use, no broader claim could well have been allowed. Each part, and the arrangement of the parts, are essential elements of the invention. The use of all hut one, omitting the one, would not be an infringement of the patent.

The first question to determine, therefore, naturally is whether the. defendants do use the entire handle as described in the patent, with all its parts, and their arrangement; and I think this question must be answered in the affirmative. The handles made by the defend-, ants, and l'or the making of which they are prosecuted in this suit,, are such as are described in letters patent granted to one Elijah li. Osgood on the eleventh of November, 1879. The answer of the defendants states that the handles made by them were and are made in accordance with said letters patent, and these letters patent were put in evidence. Besides this, specimens of the handles made by the de[744] fendants have also been produced in the case as exhibits. From this evidence it appears that the handles made by the defendants consist of a wooden handle, a ferrule, a washer, a serew-nut, and a shank having a slot for the saw, all having the mutual “arrangement,” and “being constructed, arranged, and operating substantially as described, and for the purpose set forth,” in Donoughe’s patent. The only pretense of a variance is in the mode of connecting the washer to the ferrule, the connection being by means of a flange on the outside of the ferrule, over which a flange or brackets projecting from the washer are extended, so as to make precisely the same loose connection between the ferrule and the washer as is pointed out and provided for in Donoughe’s patent. The difference is only in form. There is no difference in substance. Every element of the invention claimed by Donoughe, and patented to him, is contained in the defendants’ handles. I think that the infringement is clearly made out.
