203 F. 707 | 3rd Cir. | 1913
In the court below (he Yale & Towne Manufacturing Company, a corporate citizen of Connecticut,
“I cannot distinguish this case from Singer Mfg. Co. v. June Mfg. Co., 163 U. S. 169 116 Sup. Ct. 1002, 41 L. Ed. 118], and similar decisions. The ‘Triplex’ block was patented in 1889, but, as the patent has now expired, the defendant had a lawful right to make the article. Moreover, as the word ‘Triplex’ is not a descriptive bjut an arbitrary word', and is undoubtedly associated in the public mind with the patented article, the defendant had the right to use the word on the expiration of the patent, provided he took the proper care to prevent his own goods from being confused with the goods of the original manufacturer. This he has taken; he uses the word ‘Tribloc’ instead of ‘Triplex,’ and (what is probably more important) he adds his own name as the name of the maker, and also the place of manufacture. On the authority of the cases referred to, the bill must be dismissed with costs.”
From a decree dismissing the bill the plaintiff took the present appeal. After argument and full consideration, we think this brief opinion accurately summarizes and correctly decides the case. The plaintiff a number of years ago began manufacturing a hoisting block in which the spur gears of the block wheel engaged the links of a pull chain. The testimony of the plaintiff’s president was that plaintiff commenced the manufacture of chain blocks—
“by the obtaining of an exclusive license for the United States under the patents of Thomas A. Weston, covering the differential pulley block. A little later we took over the business of three or four other manufacturers who had been infringing the Weston patents, included among whose lines were a spur-geared type of differential pulley block. The business grew from year to year, and was combined later with the manufacture of cranes in which we did a large business for some time. We then discussed with Mr. Weston the desirability of a chain block having higher mechanical efficiency than the differential block, with the result that he took up the study of this question, developed successive ideas and designs, which we tested experimentally, this work covering upwards of three years. The final result was the development of the block which is in issue in this suit, which we put upon the market in 1890. * * * During the three years or more of experimentation preceding the placing of the block upon the market, we commonly referred to it as the ‘spur-geared block,’ to which we also frequently added the inventor’s name, thus calling it, ‘Weston’s spur-geared ■ pulley block.’ * * * We have always used those names, as descriptive of the block and its type of mechanical construction, but, when we were prexjaring to place it on the market, we thought it expedient to associate another name which would be indicative of the source of origin; that is, would indicate briefly by a handy word, when that word became'familiar to the public, the fact that the block was made by the Yale & Towne Manufacturing Company. We considered a large number of arbitrary and fanciful words and finally selected the word ‘Triplex’ from among them.”
The blocks were marked “patented June 5th, 1886, October 18th, 1889,” which were the successive patents, granted to Weston, and which references, as testified by the same witness, “indicate or are intended to indicate that the block embodies the invention of those patents.” On the expiration of these patents, the exclusive right of the plaintiff ended, and the complete right to the enjoyment of Weston’s invention became vested in the public, and the enjoyment of that right by the public was its first benefit in return for the exclusive right given to. Weston. But during the years of his enjoyment of that ex-
In accordance with these views, the decree below will be affirmed.
