Yates v. Jones, 85 F. Supp. 615, 458 U.S.P.Q. (BNA) 458, 1948 U.S. Dist. LEXIS 3072 (E.D. Va. 1948).

Opinion

BRYAN, District Judge.

A railroad locomotive coalstoker distributor plate, for which the plaintiff Yates holds letters patent No. 2,408,358, is said to have been imitated by the defendants, in their manufacture and use of the Berkley plate, and this action seeks injunctive and indemnitory relief against the infringement charged.

A distributor plate is fitted into the door of the firebox of a locomotive, and is the last conduit through which the coal passes, impelled by the stoker screw, from the locomotive tender into the firebox. The conventional firebox is rectangular in shape, some 5 or 6 feet in width and from 8 to 9 feet long. Efficient operation of a locomotive requires the maintenance of a constant head of steam, and this can be accomplished economically only by an even firebed.

Normally the coal leaves the worm and enters the firebox by crossing the firedoor threshhold or step, which is the initially involved part of the distributor. It falls by gravity off the step into the box, and would accumulate just below the firedoor, were it not, while falling, blown and spread by steam from numerous jets, arranged horizontally immediately beneath the step and in what might be termed the riser of the step. The jets expel the steam with such force as to protect and scatter the coal forward into the firebox. Steam is forced into these jets from separate compartments. The fireman may adjust the steam pressure in each jet and thus control the spread of coal.

Difficulty was experienced, however, in directing the coal into the rear corners of the firebox, that is, to the immediate right and left of the firedoor. This difficulty is readily understood when it is remembered that the door is in the center of the rear wall of the firebox, and that the jets are aimed straight ahead. Manual shifting of the coal was therefore frequently necessary, to overcome the failure of the automatic spreading process uniformly to cover the floor of the firebox; otherwise there resulted an irregularity of draft and consequent reduction in the head of steam. The correction of this mechanical deficiency was the object of both the Yates patent and the new Berkley distributor.

Prior to the summer of 1945 the Berkley distributor pláte was manufactured by the defendant Berkley Machine Works & Foundry Co., Inc., herein designated Berkley, and used by the Seaboard Air Line Railway Company on its locomotives, in the design and having the operation just outlined. That summer the Berkley plate, as it appeared on the Seaboard engines, adopted a new design to solve the previous inefficiency in the automatic feed. In substance, it was this:

The jets were relocated and placed nearer the middle of the riser, thus leaving space (on each side) between the outermost jets and the ends of the first step, so that the coal in the outer edges of the stream would not fall over and into the line of discharge of the forwardly directed jets. There was added a tray or table, some 5 or 6 inches wide, extending into the firebox, and running horizontally for almost the width of the first step, but below it and below the line of jets. Actually it was a second step with the trajectory of the forwardly directed jets above and [617]*617across it. Protruding straight ahead into the firebox at each end of the second step, but beneath it, was a steam jet-chamber or nozzle, which was farther advanced into the firebox than were the first-mentioned or forwardly directed jets. The second step is actually an iron plate bridging the space between the two jet-chambers or nozzles. On the outer side, and near the end, of each of such projecting members were jets facing to the side walls and rear corners of the firebox. These were known as advanced, lower, lateral jets, because they were situated further into the firebox than the other jets, on each end of the second step (and thus below the other jets) and were aimed at right angles to the course of the other jets. All of this comprised the upper or back member of the distributor plate.

Into the upper member and close under the second step was fitted a firing plate, in such manner that the projections or nozzles containing the lateral jets fitted into recesses in the firing plate. The firing plate was wider than the second step and allowed the lateral jets to discharge over its end surfaces. This firing plate is variously designated as the depending member, lower member or the front piece.

The operation of the new plate was such that as the coal dropped by gravity from the first step onto the second step, the coal in the center of the stream was sprayed forward, by the upper jets, into the fore parts of the firebox; while the coal in the outer edges of the coal stream fell to the side, and out of the reach, of the upper and forwardly aimed jets, onto the surface of the firing plate, in the course of which it was blown to the sides and rear corners of the firebox by the lower, lateral, advanced jets.

The new Berkley plate in a large measure accomplished the desideratum — it threw the coal into the rear corners of the box by means of the advanced lateral jets, and into the front part of the firebox by the common or forward jets. In this operation and in the design therefor, Yates says, the Berkley plate, which has been extensively made and sold by the defendant, Berkley, and used equally extensively by the defendant Seaboard, infringes his patent. Undoubtedly the operation of the Berkley and the Yates plates is generally similar. The Yates plate has the two nozzles, with the lateral jets; these jets are lower than the forwardly directed j ets; and they are advanced jets. It also has the firing plate situated below the upper jets. There are, however, important differences in their construction, and these are discussed later.

The claims of invention in the Yates patent are twofold: (1) the already mentioned lower, lateral, advanced jets and (2) the firing plate also already described. The plaintiff says, too; that it was not a coincidence that in the early summer of 1945 the Berkley plate for the first time appeared with the advanced, lower, lateral jets and with the firing plate, because on May 7, 1945 he had applied for his patent (issued September 24, 1946), and that in May his conception, he says, was revealed to Berkley and its president, the defendant Samuel G. Jones. He charges a deliberate appropriation of his ideas.

But the Court thinks the plaintiff’s case must fail because (1) his patent is invalid as lacking in invention and novelty, (2) the Berkley plate does not infringe the patent, and (3) no theft of the plaintiff’s idea has been proved, but rather the prior ownership of the idea by Berkley.

I. While the addition of the lateral jets, as well as the firing plate, was important in distributing the coal, the Court does not consider they constitute invention. The idea behind them was nothing more than the carrying forward of an old and well known process of spreading coal about the firebox by use of steam jets. The basic idea of this process is simply that the coal could be directed as desired by turning the steam in that direction, which obviously includes the idea that to get the coal into the rear corners and to rear sides of the box, the steam must be directed to those parts. Adoption of lateral jets to that end, appears to the Court as a solution which would have occurred to almost anyone observing the spraying of the coal. To send the coal to the side or to the rear corners clearly re[618]*618qui'red steam jets "facing in those directions.
