McManus v. Hammer, 38 App. D.C. 294, 1912 U.S. App. LEXIS 2126 (D.C. Cir. 1912).

Opinion

Mr. Justice Robb

delivered the opinion of the Court:

This is an appeal from a decision of an Assistant Commissioner of Patents in an interference proceeding, awarding priority of invention to Charles E. Hammer, the senior party and patentee. The patent to Hammer was inadvertently issued, as the Charles McManus application was on file at the time.

The invention is a comparatively simple one, easily understood, and relates to an improved bottle and jar closing device. Part of the claims cover a dished disk, which is nothing more than a piece of paper or cardboard cut round to fit snugly into the top of the bottle neck, and a so-called rabbeted portion of the bottle, which expression, reduced to common phrase, means that the inside top portion of the neck is cut out sufficiently to admit the disk, so that when the bottle cap is screwed down the disk will be about even with the top of the bottle; in other words, a little shoulder is made in the inside of the neck, upon which this disk rests. Another feature of some of these counts relates to the form of the top of the bottle cap, which is required to be depressed, so that when the cap is screwed down the depression will come in contact with the dished disk and, of course, force it tightly into place. The other set of counts relates particularly to the cap, and the manner of applying it to .the bottle. Under these counts the cap is required to have a plurality of inclined notches at its lower edge, which in practice simply means that the lower edge of the cap is bent inward in a plurality of places, so that the projections thereby produced will engage the separated threads which these counts .required to be formed on the exterior of the bottle, and which threads run slantingly downward to a shoulder. The counts of the issue are six in number, but counts 1, 2, and 4 fully illus[296]*296trate the different features of the invention, and are here reproduced :

“1. A bottle or jar having a rabbeted portion, a dished disk adapted to fit said rabbeted portion, and a cap adapted to flatten said dished disk to increase its diameter.

“2. A bottle or jar having a rabbeted portion, a dished disk adapted to fit into said rabbeted portion, and a cap having a depression in its end adapted to flatten the dished disk to increase its diameter.”

“4. A bottle or jar provided with an annular shoulder and a plurality of superposed separated threads connecting at their lower ends with said shoulder, in combination with a cap having one or more impunched projections at its lower edge to engage said threads, said projections being provided with inclined upper walls having an annular arrangement with relation to the lower edge of the cap conforming to the annular arrangement of the threads with relation to the shoulder, whereby stops are provided at the junction of the threads with the shoulder to limit the turning movement of the cap, the relative annular arrangement of the parts being such as to adapt the cap to be screwed down into close contact with the shoulder so that the inclined upper walls of the projections and basal edges of the inner walls thereof will respectively bear against the threads and shoulder, and exert resisting pressures to prevent injury to the projections when the cap is screwed on.”

The real question involved is that of originality. Although we have carefully examined the entire record, which is needlessly long and involved, we will content ourselves with a statement of what we conceive to be the material facts. McManus, prior to the events culminating in this controversy, had for some time interested himself in bottle closing devices. On January 27, 1904, he applied for a patent on a rim with annular grooves and a cap to fit the grooves. This application was allowed June 14, 1904, as patent No. 762,745. His next application was filed May 24, 1904, and was granted as patent No. 772,250, on October 11th following. On June 3, 1905, [297]*297he filed an application on a device similar to the one in issue, the essential differences being that the separated threads ended in a horizontal groove, instead of a shoulder, and the inside of the neck was not rabbeted. The notches in the lower part of the cap in the earlier device were straight instead of inclined, —a mechanical detail. While Hammer applied for a patent other than the one in issue on May 22, 1905, — which, so far as the record discloses, was never granted, — it is clearly apparent that McManus possessed far greater knowledge of the art than he. They were both young men, and had been acquainted in Baltimore, Maryland, for some time.

At the end of May, 1904, McManus, who had been working in Philadelphia, went to New York and engaged board and room with a Mr. and Mrs. Furness. The evidence is clear and convincing that he was then busily engaged in developing his ideas relative to bottle closing devices. McManus testifies that after he had applied for his second patent, he conceived the invention in issue, and that in June of 1904, he made a drawing or sketch of his invention; that he took this drawing to the Demuth Glass Factory, in Brooklyn, and exhibited it to the foreman, a Mr. Dries, who referred witness to a Mr. Shields, since deceased, the mold maker of the factory, and to whom McManus showed his drawing. McManus also left with Mr. Shields a model which he had filed out of a bottle neck or piece of wood. Mr. Shields was unable to make a bottle embodying the invention. This drawing and model were not preserved by the factory, so that McManus was unable to produce them in evidence. While Mr. Furness subsequently became financially interested in stock companies which Mc-Manus organized to exploit his inventions, his testimony and that of his wife, being consistent and evidently given in perfect good faith, is entitled to consideration. Soon after McManus had taken a room there, at the end of May, 1904, Mr. Furness interviewed him for the purpose of ascertaining his business. McManus, according to the witness, informed him that he was an inventor of bottle caps, and thereupon submitted “various samples of caps in brass and tin.” Wit[298]*298ness .becoming interested, McManus exhibited to him a crude drawing of an invention which he said he had just made. Mc-Manus explained this invention. The witness states “that the groove or ribs on the outside of the top of the bottle was run down to the shoulder, and the notch in the cap was beveled slightly, so that he (McManus) stated that the bevel in the notch would fit the groove on the outside of the bottle. And at the top of the bottle he was to have a little groove, and was to have a piece of paper or cardboard cut full so that it would belly up, so that when the cap was put on it would force the paper tight against the sides of the bottle and make a complete seal, as he termed it, and the cap was dented so that it would catch this washer in this ridge at the top of the neck of the bottle.” This description, it will be noted, fairly describes the invention. It is suggested by one of the, tribunals of the Patent Office that this witness failed to locate the projections at the lower edge of the bottle cap. It would be too great a reflection upon the intelligence of McManus to assume that he would have placed them anywhere else. The failure of this witness to couch his description in technical terms adds to, rather than detracts from, the weight of his testimony. It is apparent that he fully understood the result sought to be accomplished and the manner in which it was to be attained. Mrs.
