Opinion

JOHNSON, Circuit Judge.

The bills,- in these causes, were exhibited by the plaintiffs, as assignees, for the county of Oswego, of [48]*48certain reissued and extended letters patent, originally granted to John Deuchfield, April 20th, 1858, and numbered 19,984, for the term of fourteen years. The letters patent were reissued to Deuchfield, January 16th, 1872, and were extended, April 17th, 1872, for a further term of seven years from the time of the expiration of the original and reissued patent, April 20th, 1S72. The defendants are charged with infringing the first claim of the reissued patent In de-fence, it is insisted that the reissued letters patent are not for the same invention as the original patent and that new matter has been' introduced into the-specification, contrary to the provisions of section 53 of the patent act of July 8, 1870 (16 Stat 205). In the second place, it is claimed that the pat-entee was not the first inventor of what, if anything, was new in the invention claimed under the first claim of the reissued patent. This position is sought to be sustained by proof, 1st, that some one else made the invention, if any; 2d, by proof of several patents which are claimed to anticipate the Deuch-field patent; and, 3d, by proof of what is alleged to have been the prior use, in various instances, of that which is claimed as the invention of Deuchfield.

The reissued patent, number 4,712, dated January 16th, 1872, is for an alleged new and useful “improvement in cooling and drying meal,” which Deuchfield claimed to have invented. The amended specification annexed thereto states that Deuchfield has “invented a new and improved arrangement of means for cooling and drying meal,” and declares the invention to consist in “the peculiar arrangement of a suction fan, conveyor or conveyors, and elevators,” as thereinafter described, “whereby the meal, during its passage from the grinding stones to the bolts, is thoroughly dried and cooled within a limited space, the whole forming a simple and economical device.” The specification is accompanied by lettered drawings, which are referred to in the description: “A represents mill-stones, and A' are the curbs. The stones are arranged in the ordinary way. B represents the bed on which the stones are placed; 0 represents the spouts which convey the meal from the stones; and D is a chest which is placed horizontally on the flooring, E, and with which the blower ends of the spouts, O, communicate, as shown at a in both figures. Within the chest, D, a longitudinal shaft, P, is placed, said shaft having a spiral flanch, b, on it, as shown clearly in Pig. 1. The chest, D, is equal in length to the bed, B, so tfiat all the spouts, C, of the several stones, A, may communicate with it Within the chest D, there is also placed a zig-zag partition, E, provided with openings, c, having slides, d; and with one end of the chest, D, elevators, F', communicate, said elevators discharging their contents at e, as shown in Fig. 2. G is a fan, which is placed within a suitable box, H. The box, H, communicates with a spout, I, the lower end of which communicates with one end of the chest, D, as shown at f. The upper end of the spout, I, communicates with one end of a chest, J, as shown at g. The chest, J, contains a longitudinal shaft, K, having a screw or spiral flanch, h, on it, as plainly shown in Pig. 1, and, within the chest, J, a series of vertical plates, i, is placed and arranged, as clearly shown in Pig. 1, to form a zig-zag passage, as indicated by arrows, 1. The end of the chest opposite to that where the spout, I, communicates, is provided with an opening, j. Both shafts, P, K, are rotated by

[49]*49any proper means, in the direction indicated by the arrows, 2.” The operation is next described, as follows: “The meal passes from the stones, A, down the spouts, C, and into the lower part of the chest, D, and is conveyed by the spirally flanched shaft, F, into the elevator, F', the shaft, F, which is a conveyor, moving the meal in the direction indicated by the arrows, 3. The meal is carried up by the elevators and discharged, at e, directly into the bolts or into troughs, and may be conveyed by hopper-boys, or any suitable conveying device, into the bolts. While the meal is thus passed through the stones, A, spouts, C, and the chest, D, a suction blast is produced by the fan, G, said blast absorbing the moisture or vapor which the meal contains, and which is heated or warmed by the friction of the stones, A. The meal, therefore, is dried and cooled, and, in consequence of the time consumed during its passage through the spouts, C, and chest, D, will be perfectly acted upon by the blast, so that all free moisture will be absorbed. A portion of the finer and lighter particles of flour will follow the blast, and will be ejected up through the spout, I, and through the serpentine or winding-passage formed by the parts, i, and will settle in the outer end of the chest, J, and be conveyed by the conveyor or flanched shaft, K, to a spout, j, through which it falls into the elevators, F', and unites with the meal which is received by the elevators direct from the chest, D.” The specification proceeds: “This compound arrangement for operating on the meal while passing through the chest, D, and on .the escaped flour in the chest, J, returning the latter to the elevators, while it is extremely well adapted for large flouring mills running at high speeds and with a strong suction blast, may not be either necessary or even practicable in all cases. When the grinding friction evolves only a moderate degree of heat, the chest, J, and its apparatus, may be dispensed with, for, the blast being moderated to correspond, so small a quantity of the fine flour will be drawn through the spout, I, that such flour may be ejected on the mill floor, and may be disposed of in any convenient way, so as to enter the bolts. I do not claim forcing a current of air between a pair of mill stones, while the same is in operation, for the purpose of keeping the stones in a cool state, and preventing the heating of the grain, for, such means, although not very efficient, have been previously used; but I am not aware that parts arranged as herein shown, so as to allow the meal to be subjected to the blast during its entire, or nearly entire, passage from the stones to the bolts, and insure the perfect drying and cooling of the meal, have been previously used. I claim, therefore, as new, and desire to secure by letters patent, 1. The arrangement and combination of the suction fan. G, and spout, I, with the meal chest, D, receiving the meal from the grinding stones, and provided with a conveyor shaft, F, and elevator, F', substantially as and for the purpose set forth; 2. The arrangement and combination of the chests, D, J, shafts, F, K, elevators, F', fan, G, and spout, I, substantially as and for the purpose herein shown and-described.”

The specification annexed to the patent as originally issued April 20th, 1858, differed in some respects from that attached to the reissued patent. In the original, Deuchfleld declares himself to have invented a new and improved arrangement of means for cooling and drying meal during its passage from the grinding stones to the bolts, the underlined words being omitted in the reissue. In the original it is declared that the invention consists in the peculiar arrangement of a suction fan, conveyors and elevators. The reissue, by the insertion of the word “conveyor,” in the singular, is made to read “conveyor or conveyors,” and thus the way is prepared for the omission of one feature of the combination originally claimed.
