Opinion

ADAMS, District Judge.

This is a suit to restrain the alleged infringement by defendants of letters patent of the United States No. 545,040, dated August 20, 1895, for an improvement in rail joints and methods of forming the same. Complainant’s title to the patent is not denied, and, while the defendants Missouri Railroad Company and Edwards "Whitaker deny infringement, the same is practically admitted by the other defendant, the American Improved Rail-Joint Company, provided complainant’s patent is valid. Its validity is assailed on two grounds: First, that it involved no patentable novelty; and, second, that it was anticipated. Each of the five claims of the patent, although varying somewhat in phraseology, relates to a process for welding or firmly uniting abutting rail ends so as to make a continuous smooth track for the operation of car wheels. Although the usual amplitude of statement, considered necessary for securing a right to every conceivable variety or modification of the main object, is found in the claims, it is believed that four principal acts or operations embody all the essential processes of the patent, namely: (1) Cleaning the surfaces of the rails for a short distance from the ends to be joined; (2) heating the cleaned rail ends; (3) forming and adjusting a mold upon and around the rail ends; (4) pouring molten metal into this mold, and letting it remain there until it solidifies. It is true that different methods of heating the rail ends are suggested, such as heating the mold before it is placed in position, and allowing it to impart its heat to the inclosed ends; or, after it is placed in position, 'to pour, and continue pouring, the molten metal into and through the.mold until its contact with the mold itself and the rail ends inclosed therein has brought them to a sufficient degree of heat, then to stop the outflow or waste, and fill the mold so as to completely cover and envelop the base flanges, the web, running flanges, and joints, and let it so stand until it sets. But, whatever method is resorted to, has but one end and purpose, and that is to so heat the rail ends as to expel all moisture and prevent the effect of a chill upon the cast. The result of the four operations above mentioned, as claimed by the patent, is to unite the body of metal which surrounds the rail ends securely to the surfaces of the rail ends by the fusion of the metal; in other words, according to the specification of the patent and the argument of counsel, the method and process patented results in a molecular fusion of the rail ends themselves, and also with the intermediate and surrounding casting, so as to form a perfect and enduring union, and do away with the joints of the rail ends, and of their attending discomforts and annoyances.

The first question to be considered is whether this process involves patentable novelty. In our opinion, without entering into any detailed analysis of the evidence bearing on the state of the art, consisting generally of publications, technical works, mechanical operations, individual experiences, common knowledge, and divers patents,—all of which have been carefully considered,—the efforts of the patentee, as disclosed by this patent, belong to the [157]*157domain of mechanical skill, and not to the domain of invention. The proof shows, and common knowledge confirms, that the process of casting upon steel or iron is an old one; that the steps in the process set out in the claims.of the patent are each and all of them old, and have been for a long time familiar to, and practiced by, foundry men. The cleaning and heating of the rail ends to prepare them for perfect fusion with the cast; the making of the mold, whether of sand or iron; the heating of the mold, and preparing it for the reception of the cast; the pouring into it of the molten metal, and so filling it that all the parts are involved, and made one with the cast; and, Anally, allowing this heated, molten mass to stand long enough to solidify before removal of the mold,-—are, each and all of them, steps well known to foundry men and artisans in iron, steel, and metals, long before the application for the patent in suit was made. But it is argued that, although the same operations have been employed in divers branches of mechanical industry, they had never been successfully applied to welding or fusing rail ends so as to make a practically continuous rail for the operation of cars. The facts of the case seem to justify this contention of counsel, but it is not apparent to v. how, or in what manner, the particular method of the patent, in itself, has any tendency to overcome the difficulties which confronted the artisans, and which prevented the practical application of the process to railroad tracks. The reason assigned in argument for the difficulty involved is that the varying temperature to which railroad tracks were subject had caused such contraction of the rail ends as to pull apart the joints, or cause their breakage, in the line, when exposed to cold, and such expansion of them as to cause a buckling or contrary effect when exposed to heat or warmer temperature. The contention of complainant’s counsel is that the process of their patent, though old, when applied to street-railroad tracks, has produced a result which is new and beneficial, in this: that there is such a perfect fusion of the ends of the rails that the laws of contraction and expansion do not seriously affect them. In our opinion, this result does riotfollow from anything involved in the elements or combination of elements of the patented method, or anything involved in the operation or effect of such elements, in and of themselves. On the contrary, it is an old and familiar method, applied to a condition which is brought about by the needs of the recent changes and improvements in street-railway propulsion. The heavier cars first brought into practical use by the introduction of electric power for their propulsion, a short time before complainant’s patent was applied for, required very heavy and massive rails. These rails, in order not to interfere with other consistent public uses of the streets, were required to be so sunk into the ground and fortified by retaining walls of stone or cement, that only the upper surface of the head and running flange are exposed. Under such conditions the natural laws of expansion and contraction have less scope for operation. fThe earth and inclosing substantial support subject the deep sunken rail in a much less degree than exposed rails to the effects of changes in temperature. As a result, the main obstacle to the effective fusion of [158]*158rail ends theretofore found to exist in exposed rails, like those usually employed in steam locomotion and ordinary tramways, is largely overcome, and the old method of welding the rail ends is rendered available. If the patentee had invented some practical method of overcoming the tendency of the rails to expand and contract, according to changes in temperature, he would have invented something new and useful, but he is not entitled to a monopoly of such supposed invention merely because the well-known old process of his patent fell into a use made available by the adaptation of new conditions to new needs, with which tho patentee had no concern. If we are to give the patentee the credit of having in view at the time of his invention the new conditions connected with street-railway traction, rendered necessary by the introduction of the larger and heavier cars introduced with the electric system of propulsion (which is a very liberal interpretation to be placed upon his claims, and probably not warranted), even then his patent would be nothing but the application of a well-known method to a new use.
