Opinion

YOUNG, District Judge.

The patent involved in this case was issued to Andrew Ramsay, dated October 29, 1901, and is No. 685,410, for an apparatus for veneering brick. Only two of the six claims of the patent, the first and second, are in controversy. The defenses set up are want of novelty and noninfringement. The defense of want of novelty will be first considered. This defense may be subdivided for convenience of consideration into two inquiries as to the state of the prior art (a) as shown by certain patents, foreign and domestic, pleaded and offered in evidence; and (b) discovery and use of apparatus similar to that involved in the Ramsay patent prior to his application for a patent.

It becomes necessary to the proper consideration of the case under this defense of prior art to first determine exactly what Ramsay’s patent covers. Ramsay asserts in his specification that prior to the invention by him in the process of enameling bricks the bricks were coated by dipping them by hand in a liquid coating material, allowing that to dry, and again and again repeating the process until they were coated sufficiently thick. The thing desired in the enameling of bricks was to avoid the above objectionable methods, not only because of the time consumed by the repeated process, but because of the thinness of the .coating thereby obtained, and because the coating does not adhere to the bricks firmly enough to withstand the pressure and use to which bricks are ordinarily subjected. The complainant claimed to have discovéred the process and to have invented the apparatus by which this could be accomplished by a single operation, and that is by placing upon the “clay bar” as it emerges from the brick machine a quantity of plastic engobe which would be carried along by the moving clay bar and under a slicker beveled or inclined at an angle to the clay bar. He took the ordinary brick machine, and placed in front of the final forming or shaping die thereof, at a sufficient distance for the placing of the plastic engobe upon the exposed clay bar as it emerged from the .brick machine, an engobe applying slicker or [219]*219die having an inclined or beveled surface adjacent to the clay bar. This invention he embodied in the first claim, which is:

“1. In apparatus for coating or veneering bricks or other articles of clay, the combination with a final shaping ¿Ue of a brick machine, through which a (?lay bar is caused to issue, of an engobe applying slicker or dio, whoso roar end is semi rated from and is in front of said shaping die, so an to leave one surface of the clay bar entirely exposed and thereby adapting it to sustain the engobe in a thick plastic condition, the said slicker having an inclined or beveled surface adjacent to the clay bar.”

In his specification he shows three other slickers, 6, 7, and 8, which are to be used for “smoothing, roughening, grooving or corrugating the surface of the clay bar prior to tiie application of the engobe,” and it is argued by counsel for defendant that the expression in the claim “'final shaping die” means the slickers 6, 7, and 8 placed '. .'tween the engobe applying slicker and the forming die of the brick machine. We have carefully considered the specification and tile defendant’s expert Wadsworth’s opinion thereon, and we cannot so construe the patent. It is clear from the patent that the slickers 6, 7, and 8 were to be placed close to the forming die of the brick machine, and were to be used for preparing the clay bar after it passed the forming die of the brick machine for the reception of the engobe, and that one or more of them might he dispensed with or an additional number used. We conclude that the final shaping die as used in the claim means the die placed within the brick machine and forming a part of it. The first claim, then, is to be interpreted as the combination with a brick machine through which a clay bar is caused to pass, of an engobe applying slicker or die in front of and supported over the brick machine, and at such a distance from the machine as to permit the engobe to be applied in a plastic condition upon the exposed surface of the bar, so that the clay bar will carry the engobe forward and under the beveled slicker. It may be remarked that the hopper 12, by means of which the engobe might be applied to the clay bar, is not an element in this claim of the patent, because in the specification, where alone it is suggested, it does not appear as an element necessary to the apparatus. Nor does the mention in the specification at all narrow the claim so as to require its use in constructing the apparatus, fn this apparatus Ramsay also in his specification suggested the use of “a table or laterally expanding shelf 11, at the point where the bar 5 is exposed.”

Claim 2 is for the combination described in claim 1, “and an engobe supporting table located between the discharge end of said machine and said slicker and projecting laterally beyond the sides of the clay bar.” This table or ledge was evidently necessary for the support of the engobe before it passed under the engobe applying slicker, so that the entire surface laterally of the clay bar to the edge of the bar might be covered by the enameling substance, and also when it was desired to cover the sides of the bar by being placed below the level of the clay bar. AVhile not necessary to the enameling of the top of the day bar as set forth in the first claim, it was necessary to the completion and perfect covering of the clay bar to the edge. The second claim [220]*220of the patent, therefore, must be interpreted as containing this table or ledge as a necessary element in the complete apparatus.

•This patent then as construed must be considered in the light of the prior art, and first, as to the alleged prior patents. The patents pleaded and offered in evidence by defendant are both foreign and domestic patents, and for convenience we shall adopt the division made by complainant’s expert Richardson in discussing them, as this classification was followed by counsel for complainant and adopted by counsel for defendant in the discussion of the case. In order to a clear understanding of this subdivision, we quote the evidence of this ex-' pert beginning on page 82 of complainant’s record:

“These prior art patents may be divided into four classes: (1) Those relating to brick-making machines; (2) those relating to apparatus for sanding a clay bar or column as it comes from the die of the brick-making machine ; (3) those that relate to apparatus for veneering other substances than clay; (4) those relating to apxoaratus or means for veneering a continuous moving column of clay after it issues from the forming or shaping die of the brick machine. This class 4 may be subdivided as follows: (a) Those machines applying the veneer as a creamy liquid; (b) those machines applying the veneer as a thick paste.”

We may dispense with the patents coming under class (3) for two-reasons : First, because' the evidence of the experts and an examination of the patents show that there was nothing in them to suggest ta a person skilled in the art of brick making the discovery; second, because they were patents for inventions not in the art of brick making but in analogous arts. Mr. Justice Brown in Potts v. Creager, 155 U. S. 597, on page 604, 15 Sup. Ct. 194, on page 198 (39 L. Ed. 275), has stated the doctrine which we think applies to this branch of the case. He says:
