Opinion

VAN DEVANTER, Circuit Judge.

This is an appeal from a, decree of dismissal of a bill for the infringement of claims 1, 2, 3r and 4 of letters patent No. 525,419, issued September 4, 1894, to the-appellant, upon the application of Avery Eugene Hoyt, and of claim. 1 of letters patent No. 616,659, issued December 27, 1898, to the-appellant upon the application of Philetus Warren Gates and Thomas W. Capen. Both patents were for improvements in gyratorystone crushers, the art in relation to which is shown to have been. [701]*701well advanced. The construction and operation oí such a crusher are sufficiently described as follows: Its frame is in the nature of an upright cylinder consisting of two parts, designated as a bottom shell and a top shell, which are rigidly fastened together by means of bolts inserted in exterior flanges at the point of union. The top shell has a removable lining of sectional plates of chilled material, called concaves, forming a crushing chamber open at the top and bottom and shaped like an inverted truncated cone. Inside of this chamber and mounted upon a gyratory shaft is a crushing head of chilled material resembling a truncated cone. A spider, which is a vertical bearing box connected by two or three arms or legs with an annular rim, surmounts and is rigidly secured to the top shell. The shaft is engaged at its top in the bearing in the spider and at its lower end, which is within or below the lower shell, is mounted in an eccentric. When it is gyrated the crushing head is given a wabbling motion, like that of a top in the final effort of spinning, and is always approaching the concaves at one point as it recedes from them at another. The stone- is delivered at the openings between the arms of the spider by means of a hopper and falls into the space between the crushing head and the concaves, as will be readily understood from the following representation of the top of the machine :
