Opinion

Blodgett, I.

This is a bill in equity for an injunction and accounting, by reason of the alleged infringement of patent Ho. 434,087, granted [723]*723August 12,'1890, to Charles Leib, for an “electric rail-connector.” The purpose of the device is to secure a more continuous electrical connection between the rails of electric railroads, whereby a more perfect electric circuit is secured. Briefly described, the rail-connector in question consists of a short metallic wire, each end of which is passed through the head of a bolt or rivet, and those rivets firmly inserted in holes drilled into the rails to be connected. The claims of the patent are:

"(1) A rail-connector comprising a rod or wire having pins extending transversely across its ends, tiie rod passing through the pins, substantially as set forth. (2) A rail-connector comprising a rod or wire having tapering pins extending transversely across its ends, and projecting beyond the rod or wire at all sides thereof, substantially as set forth.”

The patentee says in his specification:

“My invention * * * is designed to obviate defects in the methods and devices heretofore employed; and it consists in making terminals or pins which enter the rails integral, or practically so, with the connecting wire or bar which extends from one to the other.”

The defenses insisted upon are: (1) Want of patentable novelty; (2) that defendants do not infringe.

The proof in the ease seems to establish the proposition that these wire connections between rails of the track of an electric railway are not indispensable to the operation of an electric railway, but that bet--ter work by the motors is secured by a wire connection of the rails than by relying solely upon the connection of the rails by the fish-plates; the metallic contact of the fish-plates being liable to become impaired by rust or the loosening consequent upon the vibration or jar of the rails and plates from use.

Upon the question of novelty, the defendants have introduced several prior patents, showing the state of the art prior to the device covered by the patent in question; the proof showing that the complainant first conceived his device, now covered by his patent, in 1889. The earliest device cited by the defendants is what is called “ the Bain jumper connection,” used to connect telegraph wires as early as 1870, which shows an insulated wire cable passing through the heads of a stud, at each end, and with insulated handles, and these studs, being connected with the telegraph wires to be connected, allow an electric circuit through the wire cable.

The next device in order is the patent of May, 1880, to Gassett & Fisher, in which the inventors say:

“It has been found in practice that the usual chairs or fish-plates do not in dry weather afford sulliciently good metallic continuity to form a good conductor, chieilv on account of the oxidation of the surfaces. To obviate this, elastic contact-pieces have been used, intended to be caused to rub by the deflection of the rails, and thus always afford a contact surface of bright metal. It is known, however, that a conductor composed of many pieces in contact with one another, as a wire spliced, but not soldered at many points, offers more resistance than one of continuous metal similar in all other respects to the first. * * * Our invention consists in punching or drilling holes in the flanges [724]*724of adjacent rails at convenient points near, but so as not to interfere with, the rail-joint, and driving into these holes the ends of a wire-connector long enough to reach between them and span the rail-joint, the said connector being provided at its ends with driving-studs a trifle larger in diameter than the holes, and tapering, so that when they are forcibly driven into the holes in the rail they form a perfect and permanent contact therewith, and, on account of the taper, fit so tightly that they cannot be driven out or removed except by a special instrument for drawing them, thus removing from them any scale or loose or tarnished surface, and leaving the surface thereof bright where it comes in contact with the rail, such bright metallic surfaces, forced together, insuring a perfect electric' connection. The ends of the wire-connector are coiled around the said driving-studs just under their heads, and the whole end then dipped in molten solder or other suitable metal.”

Here we find a device which is, in principle of operation and mechanical construction, exactly like that described in the complainant's patent, except that the ends of the connecting wire are wound around the head of the stud or rivet which is inserted in the rail, instead of being inserted in the head of the rivet, as called for in complainant’s patent. The difficulty to be overcome and the end to be attained by such a connection is clearly set forth in this old Gassett & Fisher patent, and the only difference is that, in the old device, the ends of the wire were closely wrapped or coiled around the head of the stud which was driven into the hole in the rail, and the stud and coil dipped in moltén solder, so as to insure metallic contact and satisfactory conducting qualities.

The Westinghouse patent of July 31, 1883, shows a wire-connector, one end of which is inserted in each rail to be connected. The only essential difference of construction between this device and that covered by the complainant’s and the Gassett & Fisher patent is that the ends of the wire are inserted directly in the rails to be connected, instead of inserting the ends of the wire in a hole in the stud, or coiling the wire tightly around the head of the stud, and driving the stud into the holes drilled in the rails. One of the forms of construction of the complainant’s patent, as shown in Fig. 2 of his drawings attached to his patent', was to upset the end of the connecting wire, and swage it up, so as to form on it two pins adapted to be driven into holes in the rails, thereby dispensing with the studs or rivets, and making his connector from one piece of metal. In other words, the connector and the rivets or studs, which entered into the holes drilled in the rails, were integral. I cannot see, if this patentee could construct his device of a single piece of metal, one end driven into the hole in one rail and the other end driven into the hole in the other rail, how it is possible to distinguish the device, either as an invention or as a mechanical structure, from that covered by the Westinghouse patent. Westinghouse took a single wire, bent a short portion of each end at a right angle, and inserted this short right-angled piece in the holes drilled for that purpose in the rails. He does not provide for upsetting or swaging the ends of the wire, but that would be a mere mechanical operation, desirable or not, according to the size of the wire used, or the size of the holes drilled in the rails. [725]*725There could be no invention in the mere matter of swaging up or upset-ing the ends of the wire in order to form a larger stud, or what takes the place of a stud at the ends of the wire. Then, there is the Winton patent of April 14, 1885, which shows a rail-connector consisting of a wire, the ends of which are firmly driven or pressed into holes drilled or Hunched in the flanges of the rails to be connected.
