APPEAL FROM THE CIRCUIT COURT OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK.delivered the opinion of the court.
This is a suit in equity, brought in the Circuit Court of the United States for the Southern District of New York, by Hamline Q. French against Oliver S. Carter, George Mark, and Milton H. St. John, to recover for the infringement of letters patent No. 244,224, granted to the plaintiff July 12, 1881, for an improvement in “roofs for vaults.” Issue was joined, proofs were taken, and the case was heard by Judge Shipman, resulting in a decree dismissing the bill, from which the plaintiff has appealed. The opinion of Judge Shipman is reported in 25 Fed. Rep. 41 .
The specification, claims, and drawings of the patent are as follows: “ My improvements relate to the construction of roofs for vaults, mausoleums, and structures of similar character, built of stone and intended for burial purposes; and the object of my invention is to obtain a building'without vertical joints, and oné held together -and locked at the roof, so that by the locking and the weight of the roof the structure shall be made as enduring as the material of which it is built. My improved roof consists of the front and rear gable-stones, the roof-stones, which are continuous from one gable-stone to the other at each side, and held to the gable-stones by mortise and tenon or equivalent connections, and the cap-stone, which is formed with a rabbet to lap upon the roof-stones and rests upon the gables, by which construction the stones forming the complete roof are securely locked, and without possibility of dislocation without being raised bodily upward.
“My invention is shown in the accompanying drawings, forming part of this specification,' wherein Fig. l is a front ' elevation, partially in section, of a vault constructed in accordance with my invention. Fig. 2 is a plan view of the same?
“ 1. A roof for vaults and similar structures, consisting of the continuous roof-stones B B, gable-stones, A, connecting and locked to the roof-stones, and the cap-stone, C, lapping upon the roof-stones, substantially as shown and described.
“ 2. In roofs for vaults and similar structures, the combination of continuous roof-stones B B and gable-stones A A, connected and locked by mortises-and tenons, or equivalent devices, substantially as shown and described.”
There was put in evidence in the case volume 13, with plates 39 to 44, both inclusive, of a public work, published in France, in 1855j called “ Bevue Genérale de 1’Architecture et de Travaux Publics,” containing a description and illustration of a monument erected in 1847, as a place of burial for the family of Alc. Billaud. This.very imperfect translation of the text is
Two drawings on one of the plates are as follows, one being a cross-section and the other a longitudinal section:
In reference to the description and drawings of the Billaud tomb, the opinion says“ The plates which are attached to the description show that the Billaud roof consists of two sloping roof-stones, each being a single piece, fastened by projections and cavities to gable-stones, each being in one piece, and a single ridge-stone, covering the joint where the upper edges of the roof-stones meet, and not resting on the gable-stones. The difference between the Billaud roof and the roof of the patent is, that the roof-stones of the former are so wide that only a ridge-stone is needed to cover the joint, while the roof-stones of the latter are narrower, and a wider ridge-stone or cap-stone is needed, which must, of course, be interposed between the roof-stones, and must rest upon the gable. The ridge-stone of the Billaud tomb is a small cap-stone, which bound the roof-stones together, and which covered the joint made by their edges. The cap-stone of the patent is a larger
We concur with the Circuit Court in its views. Where the roof-stones are wider, as in the Billaud roof, there need be only a narrow ridge-stone, while where the roof-stones are narrower, as in the patented device, a wider ridge-stone or cap-stone is necessary. In the latter case the cap-stone must rest upon the gable-stones. In the former case it need not do so. But, in each case, the vertical seam into which water could enter, is covered, and the structure is held together and locked at the roof, so as to be made enduring by the locking and the weight of the roof. The question is one of degree only, as to the size of the ridge-stone or cap-stone and the corresponding width of the roof-stones. The difference between mechanical skill and the exercise of the inventive faculty has been pointed out in many decisions of this court. Burt v. Every, 133 U. S. 349 , and cases there cited.
Thé foreign publication is competent as evidence in regard to the state of the art, and as a foundation for the inquiry whether it required invention to pass from the Billaud structure to the patented structure.
Decree affirmed.
