APPEAL FROM THE CIRCUIT COURT OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF NEW YORK.
MR. JUSTICE SHIRAS delivered the opinion of the court.
This is an appeal from a decree of the Circuit Court of the United States for the Southern District of New York, dismissing a bill filed to restrain the infringement of letters patent of the United States, No. 298,303, granted May 6, 1884, to George Krementz, of Newark, New Jersey, for a new and improved collar button.
Complainant's evidence, tending to show that the collar button made by the defendants was within the claim of the patent in suit, and constituted an infringement, was not contradicted or disputed, but it was held by the court below that the patent was invalid for want of novelty. 39 Fed. Rep. 323.
In his specification the patentee states that his invention consists in a collar button having a hollow head and stem, the said button being formed and shaped out of a single continuous plate of sheet metal. The method or process of making the button is thus described:
"By means of suitable dies a metal plate is pressed into the shape shown in Figure 2 -- that is, the plate is provided with a hollow stem, B, the sides of which are pressed together at about the middle, in some suitable manner, to form a head, C, at the end of the stem, as in Figure 3; then the head is pressed toward the base plate or back, D, whereby the head will be upset, and will have the shape shown in Figures 4 and 5. By
this operation the head is hardened. The base plate or back, D, is then rounded out and finished, and its edge is turned over, as shown in Figure 5."
In the accompanying diagram Figure 1 is a side view of the completed button. Figures 2, 3, 4 and 5 are cross-sectional elevations of the same in the different stages of the operation of making it.

The advantages attributed to the invention are the doing away with soldered joints, the lightness of the hollow stem and head as compared with buttons having solid stems and head, and the cheapness arising from the use of less material, with equal or superior strength, which, when gold is used, is quite appreciable.
The learned judge in the court below contented himself with comparing Krementz's invention with two earlier patents, one to Stokes, No. 171,882, granted January 4, 1876, and one to Keats, No. 177,253, granted May 9, 1876, in which patents, he ...
