DILLON, Circuit Judge.
On the 11th day of June, 1867, the plaintiff received a patent for an improved well-tube,' and files a bill charging the defendants with infringing his patent, and asking an account of profits and an injunction.
The answer denies that the plaintiff was the original and first inventor; states the invention claimed by the plaintiff was previously invented by one Rabbit, and others, and denies the alleged infringement, though the defendants admit that they have used a well-tube of the character they describe.
Upon the evidence before us, the court is not able to say that it has been established that the plaintiff is not the original and first inventor of the combination and arrangement claimed by him to be new.
It seems to us that the value of the plaintiff’s invention consists in the wire gauze securely fastened to the outside of the perforated well-tube; and that the tube used by the defendants is made upon substantially the same principle. The use of wire, instead of solder, to fasten or secure the screen or gauze in its place, does not prevent the defendants’ tube from being an infringement of the plaintiff’s. The principal doubt we have had relates not to the priority or value of the plaintiff’s invention, but to the sufficiency of the description of his claim; but we have thought it our duty to resolve the doubt in favor of the patentee. On the whole, we think the plaintiff entitled to an injunction, and to an account of damages and profits.
Ordered accordingly.
