Pomace Holder Co. v. Ferguson

Mr. Justice Blatchford delivered the opinion of the court. This is a suit in equity brought in the Circuit Court of the United States for the Northern District of New York, for the infringement of letters-patent No. 187,100, -granted to John Clark, February 6th, 1877, for an “improvement in cheese-formers for cider-presses,” on an application filed September 11th, 1876. The specification and drawings of the patent are as follows: • *336 secure uniformity of thickness of all the layers in the mass or cheese, and thus secure uniform pressure on its entire area, and to avoid all tendency to break the pomace frames or rack. *335 “The object I have in view is, in laying up a ‘cheese’ for' the cider-press, where each layer is folded up in a cloth, to *336 To this end it consists in the employment of a guide-frame, in combination with extended pomace-racks, as more fully hereinafter set forth. Figure 1 is a perspective view, showing the manner of laying up a cheese in press. Fig. 2 is a cross-sec *337 tion at xx. In the drawing, A’ represents the lower framework of a cider-press, on which is laid a bed, B. C is a pomace-rack, which may be rigid, as shown, .or flexible, as described in letters-patent No. 118,034, issued to me March 3,-'1874. On this rack is laid a guide-frame, D, whose bottom: girts” are not spaced-far enough apart to extend the full length of the rack on which they rest. A cloth, E, large enough to envelop the layer, is then laid on the rack, inside the frame, and opened out to receive the pomace, Avhich is ‘ struck ’ level with the girts of the frame, after which the cloth is folded over the levelled pomace, and the frame is lifted off. The' next and succeeding racks are in like manner laid on the first, and filled up, and a follower is placed on the upper one, when the cheese is ready to press. Laid up in this way, the several layers are uniform in thickness, and the cheese, in mass, 'is level on top, and offers a uniform resistance to the pressure, over its entire area, thus assuring the expression of all the juice and precluding-all danger of breaking the pomace-racks. If the bed B be extended, a cheese may be built upon a board" while one is being pressed,' and then be .slid under the follower Avhen the first one is removed.” The claim is' in these Avords: “ The guide-frame D, in combination AArith an extended pomace-rack, and a cloth to enclose a layer of pomace therein, substantially as described.’5 The ansAver sets up, as defences, Avant of novelty, want of patentability, and public use for more than tAVo years before the application for the patent. After a hearing on proofs,' a decree Avas made adjudging the patent to be invalid and dismissing the bill. The plaintiff has appealed. The decision of the Circuit Court, 21 Blatchford, 376,. proceeded on these grounds: (1.) Cloths, and also racks, and also guide-frames, having each been used before, the. aggregation of them, as described in the patent, was not a valid combination. (2.) The use of the described guide-frame, in connection with the racks and cloths, did- not involve invention. (3.) The precise combination described in the patent Avas in public use more than íavo years before the patent Avas. applied for. . *338 Without examining, any other, question raised in-the ease,-, we- are of opinion that the patent must be held void oti. the second ground abo've mentioned. A rack on which to place the pomace was1 old, and a cloth to cover the pomace lying on the rack was old, the two being used in connection, and an enclosure was used with them, which enabled the operator to make the pomace of uniform depth on each ráck, and pre-. vented the'lateral spreading of the pomace. The only point of the invention would seem to be the use of a guide-frame-smaller., than the rack, or, in- other words, the use of a rack -larger than the guide-frame. There was no invention in making the ■ guide-frame or the rack of the desired size. It required only ordinary mechanical' skill and judgment. "Within th¿ recent cases in this court on the subject the patent must be held void. Vinton v. Hamilton, 104 U. S. 485 ; Hall v. Macneale, 107 U. S. 90; Atlantic Works v. Brady, 107 U.
