I cannot hold that the plaintiff has established that any infringement of his patent by the defendants, or any of them, took place before this suit was commenced. The Hydrating ease, or condenser, made and delivered by Jones and H. H. Pawling to the Waterford mill, after the plaintiff’s patent was granted, and before this suit was commenced, had at that time no arrangement for water sealing, nor does it appear, nor can it be inferred, that they there intended that it should afterwards have applied to it any arrangement for water sealing'. The plaintiff’s patent was issued January 30, 1877. This bill was filed February 21, 1877. Only one of the two patents granted to the defendant Jones was applied for before the plaintiff’s patent was issued, or before this suit was brought. That patent, No. 185,640, was applied for December 14, 1876. That patent showed a water-sealing device. Jones’ second patent, No. 188,801, was applied for March 12, 1877. As issued, it shows a water-sealing device, but such device was not invented by Jones until after this suit was brought. There is no evidence that it was intended, when the apparatus was sent to the Waterford mill, that it should have the water-sealing device shown in patent No. 185,640, or any *713water-sealing device. Oí course, it could not then have been intended that it should have the yet uniiivented water-sealing device of patent No. 188,801. The water-sealing device after-wards put upon the apparatus was not the water-sealing device of either. No. 185,640 or No. 188,801. A water-sealing device is an essential part of the plaintiff's first claim, which is the only claim alleged to have been infringed.
It is shown that nothing was done towards putting any water-sealing device into the apparatus before this suit was brought; that there was no prior agreement or understanding that the machine should he put up with a water-sealed communication, or with the particular construction of discharge pipes which were afterwards applied to the machine; and that it was not absolutely necessary that the discharge pipe should he so constructed as to be water sealed. I do not think the case is brought within the class of cases where the seller of parts of a patented combination is liable for infringement if there ho a concert of action, proved or legally inferable, between him and others who supply other parts necessary to the complete combination. It is not shown that the defendants intended to water seal the apparatus, or that it should be water sealed. This might have been shown, as a fact, hut it was not shown. It appears that the apparatus, after being water sealed after this suit was brought, was subsequently altered so as to be used without a water seal. Hence the use of a water seal was not a necessary incident to the apparatus, so as to lead to the conclusion that the con* straction and sale of the machine necessarily involved the use of a water seal. This case, therefore, does not fall within the principle of Wallace v. Holmes, 9 Blatchf. 65, and Turrell v. Spaeth, 8 O. G. 986.
The result is that the bill must be dismissed.
