Opinion

PDATT, District Judge.

This is the usual action asking for an injunction and accounting based upon an alleged infringement of letters patent No. 569,903, dated October 20, 1896, issued to Julius [415] D. C. Wenger, for an improvement in finger-nail clippers, the_ title of said letters patent being in the complainant. The claims in issue are Nos. 1 and 2:

(1) The combination of the rigid member, the spring member connected therewith by one end, coacting cutters on the disconnected ends of said members, and the operating lever pivoted on the rigid member near the cutters and having a short end extended through a perforation in the spring member, substantially as described and for the purpose specified.
(2) The combination of the rigid member longitudinally slotted, the spring member connected therewith by one end, coacting cutters at the disconnected ends of said members, the operating lever pivoted to said rigid member, and means for confining the lever when turned down into the slot of the rigid member, substantially as described and for the purpose specified.

The defenses are (1) noninfringement; (2) that, if the patent in suit shall be construed broadly enough to discover infringement,' it must be found invalid for want of invention.

Both parties have with painstaking care prepared and presented this cause. The court has examined the patent in suit and defendant’s structure in the strong light cast upon them by the prior art. It is useless to enter upon an exhaustive discussion of the matter, and I may therefore hope to be excused if I shall confine my comments to the things which strike me as essential. When the patentee approached the art there was little left to be done. Heim and Matz recognized the narrowness of the field, and frankly said so. They obtained letters patent No. 244,891, dated July 26, 1881, for an application of the lever principle to such clippers, and truthfully point out in the specifications, lines 60-66, that it was old in the art to produce finger-nail trimmers “with two hinged jaws held normally gaping by a spring and having separately attached nipping edges,” the jaws being compressed directly by the thumb and finger; and so, disclaiming broad invention, claimed as new “a pair of nail-clipping jaws, a, a', formed of a single integral piece of steel, A, which jaws are held normally gaping by their resilience, and are closed by a cam-headed lever, C, substantially as set forth.” No. 244,891 was reissued November 1, 1881, as No. 9,921, and here a careful description shows how a cam lever can be pivoted upon a yoke fastened to one of the normally gaping spring jaws, so that it may press firmly together the jaws with their cutting edges. We have here, then, a full disclosure of the lever, with a cam action, bearing upon the outside of one of the members,, and using the other member as the one to offer the resisting force, while the lever works upon its pivot, and how a single integral piece of steel can be bent upon itself in U shape, so that it will act as its own spring, or the jaws may be hinged together and kept apart by a spring; thus admitting the equivalency of the two methods of spring action. It is true that none of the nail clippers of the lever-pressure type offer a complete anticipation of the patent in suit. The La Casse patent, No. 523,708, July 31, 1894, in Fig. 9 shows a lever acting in slots with a cam-like action, which engages the member upon which one of the cutting edges is formed, pushing it forward to cut, and pulling it back after cutting. By using the slotted member and the perforated member the patentee obtains a peculiar kind [416] of inside connection for his lever, but it is of a peculiar kind, acting in a special way, and the inventive conception does not appear to have gone beyond the peculiar method of employing certain functions, which will be pointed out. Nor can I attach any importance to the alleged novelty and inventive thought in claiming as two elements of his invention a spring member and a rigid member. Heim and Matz had two members, and one of them was rigid enough for the purpose then sought. By slotting one member in the case of the patent in suit, it is somewhat weakened, it is true, but to turn the edges of the sheet steel, and thus add resisting capacity, was an understood thing in letters patent to Browne, No. 561,482, dated June 2, 1896, and what was done is, after all, as the Patent Office examiner suggested, “merely a verbal matter,” which was, perhaps, a polite way of saying “merely a matter of words.” Both members normally gape, by reason of the resiliency, caused by turning the strip of steel upon itself, and the rigidity given to one member by turning in the edges of the strip does not divest that member of its capacity for taking part in the springing operation. It is inconceivable that one member does all the springing, the other member none; and the patentee seems to concede .this by saying “practically rigid” in his specifications. If it is more than a matter of words, then the combination of a rigid member with a spring member is shown in English patént to Gestetner, No. 8,638, July 1, 1886. It is wasteful to multiply citations on this as well as on many other points. I am in accord with, the defendant’s expert in his position that if the elements into which the claims are divided, as expressed by their terms, shall be held to include mechanical equivalents, it is easy to read them upon devices shown in the prior art; but, as I have said before, not in their entirety upon any one device. The situation demands, then, that if Wenger invented anything (and I think that he did), we must look for it around about his treatment of the lever action, and what he thought out is easily discovered. He claims an “operating lever * * * having a short end extended through a perforation in the spring member, substantially as described.” He describes the short end of the lever as for a short distance, substantially parallel to the body of said lever, and extending “down thi'ough tlie perforation 7 of the spring member.” The lever exerts its force by sliding with a cam action upon the back or outer face of the spring member, and is pivoted upon the rigid member. The cutting edges “shut squarely against each other as in cutting pliers,” and this is necessary to the inventive thought, because the force of the lever weakens after the short end has moved a certain distance, and will not remain sufficiently powerful to injure the cutting edges when they come together.
