“ The field of invention was open to any person to construct new devices or machinery by means of which to operate this old instrument in 'pebbling leather,'-in the language of the patentee in this case, 'so as to accomplish the object desired with greater rapidity and cheapness.' And this the plaintiff would have accomplished by his machine if he had not been anticipated. ”

“ In substance it is, if the jury should find that the figured roller in the plaintiff's machine was not material to the mechanical action of the roller in the combination and arrangement of the machinery by which it was moved, the leather supported, and the pressure made; and if they find that before the plaintiff's a machine was known and in use similar to his, except that the surface of the roller was smooth; and if they find that before the plaintiff's invention figured rollers were known and used in other machines for the same purpose, then the plaintiff's first claim was void. ”

“ The prayer for the second instruction to the jury prayed for by the defendant is somewhat involved and obscured by too much verbiage; but when analyzed and understood, it was clearly warranted and supported by the evidence, and should have been given. ”
