    Case No. 4,242.
    EARL v. DEXTER et al.
    [1 Ban. & A. 400; 1 Holmes, 412; 6 O. G. 729.]
    Circuit Court, D. Massachusetts.
    Sept., 1874.
    C. Howson and A. K. P. Joy, for complainant.
    H. L. Parker and Dane & Baker, for defendants.
    
      
       [Reported by Hubert A. Banning. Esq., and Henry Arden, Esq., and here reprinted by permission.]
    
   SHEPLEY, Circuit Judge.

The defendants have offered in evidence, against the objections of the complainant, certain exhibits purporting to be copies of drawings of foreign patents, accompanied with evidence respecting them, for the purpose of showing that the patentees were not the original and fii-st inventors of the improvement in apparatus for oiling wool, described in the patent, for an alleged infringement of which, this bill is brought. The answer of defendants denies that the patentees were the original and first inventors, but does not, in compliance with the statute, give any notice of the persons by whom, or the places where, the alleged invention was known or used before the invention of the patentees.

The only question, presented by the record. is one of infringement. Treating the patent as a good and valid one, as I am compelled to do on this record as against these defendants, I must come to the con-elusion that the mechanism used by the defendants for oiling wool, consisting of an oil reservoir and a sprinkler, having such a movement. imparted to it that it will enter the oil in the reservoir, and then, by percussive action, discharge the adhering oil, in the form of drops or spray, on to the wool, so as to effectually and uniformly saturate the traversing wool, is an infringement on the mechanism, patented to B. A. Earl, as assignee of B. A. Earl and Henry Holcraft. Decree for injunction and account
