Opinion

RAY, District Judge.

The validity of the patent in suit, No. 684,-776, to William M. Barnes, for “clothes drier,” has been adjudicated in this circuit and is now conceded. American Laundry Machinery Co. v. Troy Laundry Machinery Co. (C. C.) 171 Fed. 878, affirmed by Circuit Court of Appeals, Second Circuit, 174 Fed. 415, 98 C. C. A. 612. Infringement by the device to which attention will be directed is denied. In this case, now on for final hearing, this court considered this patent in some detail on a motion for preliminary injunction. American Laundry Machinery Co. v. Adams Laundry Machinery Co. (C. C.) 161 Fed. R. 556.

I am of the opinion that the six claims in issue of the patent in suit must be narrowly construed in view of the prior art, the action of the Patent Office in rejecting the original claims and the substitution by the applicant of others therefor, or of amendments which materially modified such original claims, and the acquiescence of the patentee in such action by accepting his patent as modified by the amendments.

The claims in issue read as follows:

“1. In combination, a drying-room having beating-coils extending upwardly on the side thereof, a conveyer traversing said room, the central portion of said room beneath the conveyer being devoid of heating-coils, and an air-circulating device in said room, above said conveyer, driving said air downward.
“2. In combination, a driving-room having heating-coils extending upwardly on the side thereof, a conveyer traversing said room, the central portion of said room beneath the conveyer being devoid of heating-coils, and an air-circulating device in said room, substantially central of and above said conveyer, driving said air downward.
“S. In combination, a drying-room having heating-coils extending upwardly on the sides thereof, a conveyer traversing said room, the central portion of said room beneath the conveyer being devoid of heating-coils, and an air-circulating device in said room, above said conveyer, driving said air downward.
“4. In combination, a drying-room having heating-coils extending upwardly on the' sides thereof, a conveyer traversing said room, the central portion of said room beneath the conveyer being devoid of heating-coils, and an air-circulating device in said room, substantially central of and above said conveyer, driving said air downward.
“5. The combination, with, a drying-room provided with heating-coils on the the sides only of the lower portion of said room, of a conveyer traversing said room above said heating-coils and an air-circulating, device in said room, above said conveyer and substantially central of the drying-room; said circulating device driving the air in said room downward.
“6. The combination, with a drying-room provided with heating-coils on the sides only of the lower portion of said room, of a conveyer traversing said room above said heatiug-eoils and at substantially the same level throughout, and an air-circulating device in said,room, above said conveyer and substantially central of the drying-room; said circulating device driving the air in said room downward.”

Due regard must be had to the words “the central portion of said room beneath the conveyer being devoid of heating-coils,” found in [53]*53claims 1, 2, 3, and 4, and to the words “with heating-coils on the sides [of the room] only of the lower portion of said room,” found in claims 3 and 6, as but for their insertion the claims would not have been allowed — in fact, without them were rejected. Repeatedly in the specifications of the patent stress is laid on the fact that the heating-coils are “on the sides and back of this room,” or “at the side of the room,” etc. This is an essential feature, and, as the prior art had all the elements of the combination except this feature, a drying-room which does not have it fails to infringe the claims in suit.

The alleged infringing drying-room of the defendant has heating-coils on the sides of the room; but it also has heating-coils in the central part of the room on the floor under the fan and under the conveyer. These central coils (two set) are each 16 inches from the center or median line of the room, which is some 70 inches wide, and about 19 inches from the sides, and seated on the floor. This is_ conceded by the complainant; but it contends that this placing of coils in the central part is immaterial, and a mere subterfuge to avoid infringement, and that these heating-coils in the central part of the room perform no function of any account, at least, and that the operation of the defendant's drying-room and the result attained is precisely the same without as with them, and, in either case, the same as in complainant’s drying-room. Here is the turning and decisive point of this case. If complainant is correct in its contention, infringement is made out; if incorrect, there is no infringement.

The heating-coils of defendant’s structure, located in the central part of the drying-room — that is, at the points mentioned — comprise about one-third of the efficient heatingrcoils of the room. In short, they furnish one-third of the heat and are an essential part of the drying-room. The fan which revolves in the upper central part of this room is so shaped as to drive the heated air, which rises from the coils and absorbs the moisture from the wet garments, downward], and it passes out of the room through an appropriate opening. That hot air rises is well known and conceded. The patent in suit goes on the theory t$iat as the heated air from the coils on the sides of the room rises it is driven downward, except at the sides of the room, by the fan, and into contact with the clothing carried by the carrier, not necessary to he here described, and that the tendency of such current is downward, and that in all parts of the room occupied by the moving carrier a substantially uniform heat is maintained, and that the suspended clothing is not blown upward or sidewise, hut rather downward, and that clothing is not loosened from the carrier and dropped on the heated coils on the floor, as was the case in the prior art, where coils were placed on the floor in the central part of the room.

The specifications of the complainant’s patent contain the following:

‘■By the construction described it will be seen that the heating-coils are at the sides of the room and the fan above the conveyer. The air rises from the bottom along the sides, being heated by the heating-coils, and the fan forces it downward through the center to the bottom, from which it again rises, as before described, thus producing a perfect circulation. Any damp air escapes through the opening a 3, and fresh air will be admitted through ■openings a 1 and a V

[54]*54As I understand the complainant’s expert, he concedes that if these coils in the central part of the room alleged! to infringe were placed side by side and nearer the center of the room, or laid down on the floor, there would be no infringement. These coils are nearer the center of the room than the sides, and are 19 inches distant from the sides. Clearly this drying-room of the defendant is not “provided with heating-coils on the sides only,” and “the central portion of said room beneath the conveyer” is not “devoid of heating-coils.”

Do these heating-coils in the central part of the room perform any substantial function? It seems to me very clear that they do.
