Opinion

HOLLAND, District Judge.

William M. Barnes brought this suit against John Lingo for the infringement of letters patent Nos. 684,776 and 68-4,778, both issued to Barnes October 22, 1901, for respectively a clothes drier and clothes drying machine. All the 10 claims of the first, and claims 1 to 17 inclusive and 21 and 24 of the second patent, are involved. The second of these patents relates to certain improvements upon the first, and both patents are used in the construction of a complete clothes drier as now manufactured by Barnes. The defendant has in his possession, and is using, a clothes drying machine which is identical in construction with those manufactured by the complainant, in accordance with the claims of the patents in question. As matters of defense, the defendant avers that all said claims are in[60]*60valid, first, because their subject matters are anticipated by structures of the prior art; secondly, they involve no invention as combinations, but are mere aggregations of old devices; and, thirdly, that defendant’s drier is not an infringement of said claims.

Prior to July 1900, the method of drying clothes in drying rooms was very unsatisfactory. There were two types of drying rooms used by laundrymen. One known at the “Henrici room,” provided with steam heating coils distributed upon the floor of the room. The room was provided with a number of racks or, drawers having rollers running upon tracks on the top of the room, the tracks extending beyond the fro'nt of the room. The racks or drawers were moved by hand on the tracks in and out of the room, and, when in the room, the outer ends formed or closed the front thereof. The racks were pulled out of the room and clothes to be dried hung thereon, and jvere then pushed back and remained there until the clothes were dried, when the racks were again pulled out by hand and dried goods removed and others to be dried hung thereon. This room was in use for many years, but was defective in that the heating coils being on the floor, garments dropping from the rack were burned and soiled. The whole operation being manual, required all the time of the operator to put on and take off the goods and to determine the duration they were to remain in the drying room. The process was consequently very slow.

There was also in use what was known as the “Hurricane room,” which is provided with heating coils on the sides only, and an upright section in the centre of the room, and a fan on the ceiling forcing the air downward. In this room, as in the previous room, racks were used to support the goods, which racks were either supported by wheels traveling upon overhead tracks or supported upon trucks, the wheels of which run upon tracks on the floor of the room. This room increased the heat, and thus shortened the drying operation. The whole operation, however, in placing and removing the goods and drawing the racks in and out of the room was manual. The drying was more rapid than in the Henrici room, but the evenness of drying of that room was 'lost, and goods in different parts of the Hurricane room dried with different degrees of speed; those nearest the goils drying the faster. An attendant was necessary at all times to watch the drying in order , to prevent discolorations from overdrying, and frequently the bars of the racks near the heating coils were not used, thus lowering the capacity of the room. The process of drying clothes in thesé rooms was slow and unsatisfactory. Baundrymen were endeavoring to improve the method of doing this work, and at their conventions the matter of improvement in drying rooms was a subject of much discussion by them. Barnes, by a combination of old devices, succeeded in solving the problem and furnished a drying room with none of. the defects of those previously used. He combined the uniformity -of drying of the Henrici room without its slowness, with the rapidity of drying of the Hurricane room without its nonuriiformity of drying. The capacity of the room was increased, with no danger - of burnt or soiled garments or discolorations, and finally an automatic drying room was obtained, one in the operation of which-no- attendant was required except to place the goods upon the pins. [61]*61I find from the evidence that the drying machine in the possession and used by the defendant is a device such as is covered by the first six claims of patent No. 684,776, with the improvement described in complainant’s patent No. 684,778.

A drying room, in accordance with the patent No. 684,776, as improved by patent No. 684,778, is a closed room about Qyí. feet long, ?,l/z feet wide, and 6J4 feet high, through which the clothes are slowly carried by an endless conveyor arranged on edge; that is, having the links vertically disposed, so that there is room to give the conveyor a number of turns in the room, and allow the garments to take a serpentine course in their travel through the upper part of the room. The clothes are hung by an attendant upon the conveyor at the outside of the room, near an opening into the room, and after traversing the room are automatically stripped from the conveyor by a stripping mechanism, as they pass out through an opening on the opposite side of the front of the room. The clothes are dried in the room with rapidity, because there is placed therein a number of steam-heating coils, all of which are placed along the sides of the room adjacent to the walls thereof, and below the conveyor referred to, while above the conveyor is a circular fan about two feet in diameter, belted to an outside source of power, and so arranged that, when in operation, it drives the air downwardly in tire room through tire garments as they take their sinuous course through the room.

The conveyor is constructed as follows: A number of straight tracks arranged parallel to each other in the room and forming a loop on the outside of the room, are suitably supported and receive rollers, carried on the upper ends of arms, which arms carry links of a continuous chain, from which depend short arms carrying a horizontal pin on each side. The support of the conveyor is made continuous by sprocket wheels, which engage the conveyor chain from one section of straight track to the next; the sprocket wheel being in a lower plane than the track, as clearly shown in the drawings. Thus the conveyor is at all times supported, and it is, because of its being on edge, disposed in a minimum of space, and that it can make so great number of turns backward and forward within the room. The conveyor is continuously driven by the sprocket wheel, which is carried by a vertical shaft extending upwardly through the room and operated through suitable power-transmitting connections, described in the patent, from any suitable source of power. Thus a continuous line of garments pass through all parts of the room several times at a constant and uniform level, and each receives the same treatment as to the degree of heat, and none are exposed too long to the direct radiation from the heating coils causing discoloration.

This improved room is claimed in varying language in patent No. 684,776 in claims from 1 to 6 inclusive. The last is as follows:

“The combination, with a drying room, provided with heating coils on the sides only of the lower portion of said room, of a conveyor traversing said room above said heating coils and at substantially the same level throughout, and an air-circulating device in said room abové sáid conveyor and substantially central of the drying room; said circulating device driving the air in said room downward.”
