Summary

Stanley Matthews Eachus v. Broomall — Opinion of the Court

It is plain, then, that the only invention exhibited in the drawings or described in the specifications of the original patent consists in the particular organization of the machine described, whereby the various parts are combined and adjusted so as to fit it to accomplish the specific result of cutting heavy paper when in large sheets and in a wet condition, as received from the paper-making machine, into smaller sizes and other shapes, for use as boards in book-binding and box-making.

Stanley Matthews Eachus v. Broomall — Opinion of the Court

The attempt is made, in argument on behalf of the appellant, by construction to convert the original patent into a patent for a process, in which the real invention described 'consisted in operating upon a peculiar kind of material with a peculiar kind of cutter,' and in which the claim was inadvertently framed so as to cover merely the machine itself, and not the process in which it was one only of the factors.

Stanley Matthews Eachus v. Broomall — Opinion of the Court

This description refers to the drawings, which show the machine with all its parts, and their relations to each other, in their combination. But none of these parts, either in their construction or mode of operation, or general function, are novel; for saws and shafts, and frames for carrying material to be cut, had been in common use for cutting other material, and were well known. Accordingly, the appellant, in his specification, enters an express disclaimer as to all such uses, and the combinations and arrangements of well-known machinery by which they had been effected.
