Opinion

ANDERSON, Circuit Judge.

This case was most thoroughly prepared, and has for eight days been tried before me with great ability on both sides. I can have no doubt that every material point has been adequately presented and urged. To write an opinion covering all the points raised would, considering my other assignments, require weeks perhaps months of delay, and then might be of little or no value to the parties and to the appellate court. As I have reached conclusions, I think a present expression, even if brief and somewhat crude, is preferable to the alternative of the substantial delay otherwise necessary.

[1] The plaintiff sues on a combination patent made up of devices all of which are admittedly old, with one possible exception, to which I will refer later. By this combination machine batter is, without the intervention of the human hand, molded, baked, trimmed, and turned out as finished ice cream cones. The .defendant is not charged with infringement of the general combination. There is therefore no issue [1012]*1012before me involving either validity or infringement of that general combination. But the plaintiff, not claiming infringement of its general combination, sets up three so-called subcombinations, and alleges infringement of the claims falling under each of these three subcom-binations. I think the plaintiff fails on all three points, and that the bill must be dismissed.

1. The plaintiff contends that the defendant’s .method of putting batter into the mold is the equivalent of the plaintiff’s method. The plaintiff’s method is that of dipping the cores into the batter tank by a device described as the leapfrog device. This device consists of an arm carrying the cores so operated that it lifts the cores out! of the molds, dips them into the batter tank, then comes back and replaces them in the molds. The defendant’s method consists in pouring, by a measuring device, batter into the closed molds. The cores then enter the closed molds, and as they go towards the apex the batter rises by pressure, assisted by heat, thus surrounding the core, and forming a cone as the batter is baked.

In tins respect I find and rule that the machines are different in their method of transporting batter from the tank into the mold, and that there is no infringement of any of the claims, whether valid or invalid, involving that important part of the plaintiff’s machine.

2. The second class of claims contended to be infringed are those involving the opening, closing, locking, and unlocking devices of the molds. I am far from being convinced that the plaintiff has any valid subcombination for operating the molds. The devices themselves are admitted to be old. It is only their combination in connection with these molds which can possibly be claimed to be new. It is unnecessary to reach a conclusion on that point; for, even if the plaintiff has a valid subcombination, the defendant’s devices and method of operation are quite different. Another difference is that the defendant’s device does not lock, in the proper sense of the word, the molds as they pass around the wheel. In the defendant’s machine, after the cores are by a spring pressed into the molds for two or three unit movements, they then rest in the molds by gravity. On all the evidence I find that the defendant has not in this particular infringed upon the plaintiff’s invention, if any invention there be.

3. The third class of claims on which the plaintiff most relies, and which it claims to be new, is that covering the extraction method of the baked cones from the molds, and said to be referred to most particularly in claims 66 and 67. Mr. Wadsworth, the plaintiff’s expert, contends that this extracting method is the essential idea of the plaintiff’s invention, and that it is adequately disclosed in the patent. The gist of the notion is that after the cone has been baked and is then held tightly between the inwardly projecting iron core, weighing about two pounds, and the inclosing iron molds, which open scissors fashion, the core is first slightly lifted, thus detaching it from the otherwise adherent cone, but leaving it well down in the cone; that then, as the molds open, if the cone sticks to one side or the other of the opening molds, the inwardly projecting core acts as a stripping finger or device to detach the cone from that side of the mold to which it sticks, [1013]*1013so that it will drop vertically down to the trimming device, and thence to the carrier.

I have the greatest difficulty in finding that that idea is disclosed in this patent. I cannot find it anywhere referred to in the early part of the specification, where this patentee, as is usual, makes a general description of what he says he has invented. I cannot find it in the later part of the specification, where he catalogues the advantages of his invention. Without reviewing the patent in detail, the impression made on me by repeated reading of it is that the inventor was thinking more about the probable difficulty of detaching the core from the cone than of detaching the cone from the separating molds. I find it difficult to resist the conviction that this patentee believed that, if the •baked cone were ribbed, and so held tightly by the closed molds until the core had been lifted by the cam device, and that if then both sides of the mold opened (possibly with a little snapping motion), the cone would drop down.

Even in claim 66, where the phrase “slightly lifting” so much relied upon by the plaintiff is used, I find a context ending “to thereby strip the mold product from the said core” — not from the mold. And again, in claim 67, I find language as to “lifting said core in said mold sections before said mold sections are opened, thereby stripping the mold product from the said core” — again not from the mold. Nowhere do I find any language plainly saying that the core is slightly lifted in the cone in order that the core may then strip the cone from the mold.

It is, of course, elementary that there must be a disclosure of the invention. It is also settled law that the patentee is entitled,to his entire invention if it can be found in the patent, fairly construing the specification, drawings, and claims.

" Counsel cite on this point the decision of this court in I. T. S. Rubber Co. v. Panther Rubber Mfg. Co., 260 Fed. 934, 171 C. C. A. 576. I do not believe the doctrine there laid down is applicable to this case.

[2] But, even if I were able to resolve my doubts on this point, I find an insuperable difficulty in the fact that the Brookfield & Stivers patent, No. 835,235, seems to me plainly to anticipate the idea involved in the plaintiff’s contention concerning the extraction function of the core, leaving it, after detachment from the cone, well down within the cone, so that it may, if necessary, operate to strip the baked cone from either side of the separating molds.

It is true that the Brookfield & Stivers patent refers to glass molding. Plaintiff’s counsel now argues that glass molding is not an analogous art. But he was of a different opinion when he was prosecuting the Bruckman patent in the Patent Office. I think his view then was sound, and that he is in error now. At any rate, I cannot believe that on the points now important glass molding is not an analogous art with pastry molding. The result is that on this third point also I find and rule that the plaintiff has failed to make out a case against the defendant.
