In Equity. Ooburn wThacher, for complainant. Offield, Towle wPhelp8 and M. D. Leggett, for defendants. BLODGETT, J. The plaintiff, by this bill, seeks an accounting and injunction for an alleged infringement of patent No. 96,249, granted to R. B. Mitchell, October 26, 1869, for "an improvement in kerosene stoves," and patent No. 221,206, granted November 4, 1879, and patent No. 230,850, granted August 10,1880, both to J. McGregor Adams for improvements in oil·stoves. What I said in the preceding case of Oomplainant v. John F. Rathbone, in regard to the first-named patent, makes it unnecessary to further discuss that patent in connection with this case, as the infringement is clearly shown in this case, both as to the first and second claims of that patent, under the view which I have taken of that patent in the former case, as defendants in this case use, not only the upper and lower plates and chimneys covered by the first claim, but they also use the projections cast upon the upper plate for the purpose of supporting the cooking utensil above the tops of the chimneys. As to the last·named patents, infringement is charged as to the third claim of patent 221,206, and the second claim of patent No. 2130,850. Patent No. 221,206 has reference to the oil.pot or oil reservoir of a kerosene stove, and shows what is called a "Supplementary Plate" extending over the upper surface of the oil reservoir, and resting upon a bead or ridge raised upon the upper surface of the upper plate of the oil.pot, held in place by a thumb-screw which fastens this plate firmly to the upper plate of the reservoir, which supplementary or auxiliary plate carries the wick tubes. The language of the third claim is as follows: "An oil reservoir, A. provided with a projecting top, in combination with a loose supplementary plate, D, to which the wick-tubes are attached, and a 1 Reported

thn ill h-serew, D', hy which the plate is secured to the top of the oil reservoir, substantially as described."
Patent No. 230,259 is for a safety device, in connection with the oil.pot, by constructing the filling tube with wire-gauze or perforated sheet-metal, so that if the oil or vapors inside of the filling ttl be takes fire, it will not communicate the fire to the body of the oil in the res. ervoir, and this filling tube is also provided with a tubular stopper, B', across which is a diaphragm of perforated metal or wire-gauze, which would allow the escape of the volatile gases from the filling tube; the language of the second claim being: ".A tubular stopper, B ' , fitted to the filling apperture, and provided with a perforated diaphragm, N, in combination with the perforated safety tube, h, substantially as and for the purposes specified."
An inspection of the defendant's stove, as shown in the proof, shows an auxiliary or supplementary plate over the oil reservoir in connec· tion with each wick·tube; these plates performing for each wick-tube, and the reservoir over which the several wick-tubes are pla.ced, precisely the same office as is performed by the larger plates, D, in the complainant's patent; and I have no difficulty in concluding, from an inspection alone, that the defendant's stove infringes this claim of the Adams patent of 1879; and, although the novelty of this patent is questioned in the pleadings, and some proof of anticipatory devices is put in the record, I do not find anything which anticipates or should defeat the Adams patent for this supplementary plate, D. I there. fore find that the defendant infringes the third claim of the patent of 1879. But the proof shows in a patent, granted December 20, 1868, to A. H. Emery, a stopper to a filling tube, with, so far as I am aLle to see, the same device used by defendants; that is, a stopper with one or more gauze diaphragms. I therefore find that the device covered by the second claim of the Adams patent of 1880 is anticipated by the Emery patent, and that the Adams patent of 1880 is void for want of novelty as to the second claim. The finding will therefore be that the defendant infringes the first and second claim of thA Mitchell patent of 1869, and the third claim of the Adams patent of 1879, but does not infringe the Adams patent of 1880.

PATENTS FOR INVENTIONS-CoNSTRUCTION OF CLAIM.
The combination covered by the patent in question accomplished no new result in mechanics, and differed from previous known combinations only in the construction of one or two of the parts, whereby, perhaps, a better but certainly not a different kind of result was accomplished than had been before effected. Held, that the patent must be limited to these details of construction. When an applicant for a patent acquiesces in the decision of the patentoffice, that the novelty of hIS device consists merely in an improved construction of details, the claim cannot, by a liberal construction, be made to include anything else.

SAME.
In Chancery. C. P. Jacobs, for complainants. G. H. Burchard and Parkinson ct Parkinson, for defendants. WOODS, J. 'l'he action in each of these cases is for infringement of letters patent No. 190,152, granted May I, 1877, to Alexander C. Martin, for "improvement in furniture cast.ers," the plaintiffs claiming title by virtue of certain assignments of the patent. The infringement charged against Spiegel & Co. consisted in the possession and sale of an article known as the "Yale Caster," made at New Haven, Connecticut. The complaint against Ogborn and the Richmond Caster Company, in the other case, is for the manufacture, use, and sale of casters made under letters patent No. 273,278, granted March 6, 1883, to the Richmond Caster Company, as assignee of Ogborn. Besides disputing the plaintiffs' title to the Martin patent, the defendants in each case deny infringement, and also the validity of that patent. The prior art, also, is shown by reference to numerous earlier patents, both American and English, which it is aHeRed anticipated the Martin combination entirely; or, at least, in so far as to impose upon it a strict construction, limiting it to the particular arrangement of parts described, and excluding any pretense of infringement by the defendants. After a painstaking consideration of the evidence and accompanying models, the opinions of the experts, and the arguments and briefs of counsel, which upon both sides have been quite exhaustive, I am compelled to the conclusion in each case that infringement has not been shown, and consequently that the bills must be dismissed. The combination of the patent in question accomplished no new result in mechanics, and differed from previous known combinations, designed J
