69 F. 412 | U.S. Circuit Court for the Southern District of Illnois | 1895
This suit was brought by the Consolidated Brake-Shoe Company, of New Jersey, which, at the date of the commencement of the suit, owned the legal title to letters patent of the United States numbered 174,898, issued March 21, 1870, to Isaac H. Congdon, and by the Congdon Brake-Shoe Company,
While other questions have been raised in argument and on the briefs, I have concluded that the controlling question in this case is the question of the validity of the complainants’ patent under the pleadings, the exhibits, and evidence. The specifications of the patent sued upon state:
“My invention consists of a shoe for ear brakes, having its body made of cast iron, with pieces or sections on its face of a different kind of metal, said sections being composed of malleable cast iron, steel, or wrought iron, as hereinafter more fully set forth.”
After referring to a method of constructing this brake shoe, the specifications further refer to the fact that “in all railroad shops there is always an accumulation of broken springs,” etc., that is harder refuse metal, which may be imbedded in the softer metal of the brake-shoe casing, and thus present a dual frictional surface to the wheel. It is true that the prior state of the art, as exhibited by the evidence, shows composite frictional bearing surfaces composed of different materials,—as, for instance, of wood and rubber, —and also shows a prior patent granted to one McCaffrey in 1874 for a journal bearing; but it is clear to the court that none of these prior devices were ever intended to accomplish, or did accomplish, or were capable, without further invention, of accomplishing-, the result acnomplished by Cougdon as disclosed in the patent sued
Let a decree be entered sustaining complainants’ title to the patent sued upon, as pleaded in the bill of complaint, finding that the defendants have infringed the same; that the said patent is a good and valid patent for a brake shoe for railway cars, composed of different metals, and' having inserted bearing pieces of a harder metal than the metal composing the body of the shoe; and dismissing said bill, but without costs, as to the defendants Hook and Henderson.
