Opinion

Mr. Justice McComas

delivered the opinion of the Court:

This is an appeal from a decision of the Commissioner of Patents in an interference. The subject is emergency knuckles ■for car couplers.

The issues of the interference are as follows:

“1. In automatic car couplers, an emergency coupling attachment designed to closely and interchangeably fit at one end in coupling engagement with all forms of the vertical plane type of coupler, having a rotative hook or knuckle, and provided at its other end with an opening to receive a vertical pivot pin by which it is adapted to be connected with another coupler, a ■coupling knuckle, or analogous coupling device.

“2. In automatic car couplers, an emergency coupler attachment designed to be hinged at one end to the drawhead in place •of the usual swinging knuckle, and provided at its other end with a hook and with a guard arm, the hook being adapted to nlosely and interchangeably fit, and to be automatically coupled to all forms of the vertical type of coupler having a rotative Took or knuckle.

“3. In automatic car couplers, an emergency coupler attachment designed to be hinged at one end, to the drawhead in the place of the usual knuckle, and provided at its other end with a "knuckle adapted to automatically inter-couple with the rotating knuckle of an adjacent coupler in a manner to retain the inter-coupled drawheads in substantial alinement with each other.

“4. In automatic car couplers, an emergency coupler attachment designed to be hinged at one end to the drawhead in place of the usual knuckle, and provided at its other end with a rigid knuckle, and in rear of said knuckle with a guide arm, said rigid "knuckle and guide arm being adapted to automatically inter-couple with the rotating knuckle of an adjacent coupler in a manner to retain the drawheads in substantial alinement with •each other.

“5. An emergency car-coupler knuckle comprising a lug-adapted to be pivoted between the ears of a coupler head, a guard member extending from the lug, and forming with the knuckle [411]*411head a space to receive the head of the knuckle of a co-operating coupler, and a web extending between said lug and the rear surface of said guard member.”

All of the Patent Office tribunals decided this interference in favor of James A. Hinson, the appellee, and, from the final decision of the Commissioner of Patents, George H. Gilman and .James H. Brown have taken their appeal to this court.

The appellee filed his application on August 19th, 1903.

The appellants filed their application March 14th, 1904.

The appellee died in May of the last-mentioned year, and his -case rests upon the record date of the filing of his application, and no testimony has been taken to show the date of the ap■pellee’s conception and reduction to practice of the invention. It appears from the record that the appellee’s emergency knuckle was placed on the market about the time his application was filed.

The testimony in behalf of the appellants tends to show conception and reduction to practice in 1898, although they have neither manufactured the device, nor placed it on the market.

The subject of this interference is a knuckle for car couplers, to be used in emergencies in place of a broken knuckle of any Master Gar Builders’ type.

The act of Congress of March 2d, 1893, passed in compliance with President Harrison’s earnest urgency upon Congress, and the act of March 2d, 1903, amending the prior act, greatly stimulated the production of such devices, for the first act plainly forbade the use of cars which could not be coupled together ■automatically by impact by means of the couplers actually used •on the cars to be coupled. Johnson v. Southern P. Co. 196 U. S. 16, 49 L. ed. 369, 25 Sup. Ct. Rep. 158.

In accordance with this legislation, the Master Car Builders .■adopted regulations with which all car couplers must conform. More than a hundred different types of automatic car couplers, all conforming to the Master Car Builders’ requirements, having knuckles adapted to swing in a horizontal plane upon a vertical axis, each of which is capable of interlocking with the knuckles of all other Master Car Builders’ types of couplers, [412]*412testify to the zealous interest of inventors in this field. The knuckle of each type of coupler is of special construction, capable of use only with a coupler of its own special type. It is characteristic of the knuckles of the several types that they are capable of interlocking with all other types of couplers, and also that, whatever inay be the material out of which they may be made, they are very liable to break. The latter characteristic led to the invention involved in this controversy.

A train of cars contains cars equipped with various types of Master Car Builders’ couplers. It is impossible for each train to carry a supply of knuckles of all types. Prior to 1898, when the appellants first marketed their original type of emergency knuckle, when a knuckle was broken it was usual to connect the broken coupler with the coupler on the adjoining car by means of a link and pin and this required the brakeman to go between the cars. This proved a very unsatisfactory and dangerous substitute; therefore, the purpose of the invention in issue is to provide a knuckle to co-act with any of the various forms of knuckles in use, and which can be substituted for any of those forms in case of breakage, and it is one of great importance to the railway industry.

The appellants, both practical railroad men, devised an emergency knuckle to interlock with all types of Master Car Builders’ knuckles and capable of instant use in lieu of a broken knuckle on all forms of Master Car Builders’ couplers, and obtained a patent for their invention on August 16th, 1898.

The adoption and operation of the knuckle covered by the ■patent is not material here. It suffices to notice that in using that type of emergency knuckle it becomes necessary to remove some parts of the locking mechanism in most of the different types of Master Car Builders’ couplers. This fact led the appellee to seek to devise an emergency knuckle which would replace a broken knuckle without necessitating the removal of any of the parts of locking mechanism.

The testimony in behalf of the appellants shows the conception of their device in July, 1898; the making of a sketch and the completion of a rough wooden pattern in September of that. [413]*413year, and about tbe same time tbe making of a brass casting from such pattern, and later of a finished wooden pattern and the making therefrom of a gray iron casting. In September of the same year they made a test of the brass casting, which casting appellants claim was substantially the same in construction as the emergency knuckle described and claimed in the appellants’ application involved in this interference. It was substituted for a knuckle upon a car in the yards of the Northern Pacific Railroad Company, at South Tacoma, Washington, and coupled with a car provided with a standard Master Car Builders’ coupler. A train composed of a number of cars back of the brass casting was hauled by an engine several miles, around curves and over switches in those yards. During the test the brass casting was coupled and uncoupled a number of times with the knuckle of the adjacent coupler, and never accidentally uncoupled. Before the conclusion of the test, however, the brass coupler broke.
