Laas v. Scott, 26 App. D.C. 354, 1905 U.S. App. LEXIS 5373 (D.C. Cir. 1905).

Opinion

Mr. Chief Justice Shepard

delivered the opinion of the Court:

Edward Laas and Hiram H. Sponenbnrg appeal from the decision of the Commissioner of Patents in an interference pro[356]*356ceeding, awarding priority to John M. Scott of the invention defined in the following issue:

“1. A railway-rail stay consisting of two separate rail-gripping jaws fulcrumed on the rail flanges and with horizontally prolonged bottom bearings sustained out of contact with each other and abutting the side of the tie, lugs projecting from said bottom bearings, and a bolt engaging the lugs and provided with means for drawing the jaws into engagement with the rail as set forth.

“2. A railway-rail stay consisting of separate laterally movable rail-gripping jaws, each formed with a bottom portion bearing on the under side of the rail and with a depending lug, a bolt passing through the lugs and provided with a head on one end and with a nut on the opposite end, and an abutment depending from the bottom bearing of one of the jaws as set forth and shown.”

The appellants were first to enter the Patent Office, having filed their joint application December 16, 1903, which was followed by a patent granted thereon April 19, 1901. Appellee’s application was filed March 10, 1901. The ordinary burden of proof imposed upon the latter as junior applicant is not increased by. the patent granted his opponents while his application was pending.

Scott, in his preliminary statement, alleged conception May 5, 1902; making of patterns before May 12, 1902; manufacture and putting upon sale late in 1903.

Laas and Sponenburg alleged joint conception of the invention June 21, 1903, making of model and castings on June 29, 1903.

The Examiner of Interferences decided in favor of Scott. His conclusions were, that Scott conceived iñ May, 1902', but did not reduce to practice; that there was no certain date of conception proved by the appellants prior to their filing date; and that Scott was using diligence when they entered the field. The decision of the Examiners-in-Chief is in substantial agreement. The Commissioner briefly states his acceptance of the conclusions of the other tribunals, and directs his attention to the consideration of the questions, whether Scott was entitled to make the [357]*357claims of the issue, or there was an interference in fact. Those are not before us.

Before entering upon the consideration of the points involved, it will not be irrelevant to give a brief history of the art and of the several inventors’ connection therewith. It has been long known that the rails of a railway track have a tendency to “creep,”—that is, to move longitudinally in the direction which the trains of cars take. With the great increase of weight in engines and freight cars, and the doubling of tracks through which the pressure on each track is almost entirely in one direction, the results of “creeping” have increased to such an extent as to require frequent repairing of tracks at crossings and side tracks with switches. The difficulty is particularly great at crossings of other railways.

Laas is a railway superintendent, and has been connected with steam-railway operation for about twenty-three years, as civil engineer, roadmaster, and superintendent of construction, successively. Sponenburg is a track foreman, and has been engaged in railway construction for twenty-five years. In 1898, the latter had his attention specially directed to the creeping of the rails, and in October, 1900, he filed an application for a patent for his first device to meet the condition. In the latter year he showed the device to Laas and they associated themselves together for the purpose of making improvements in the same line. Jointly, they were granted patents on July 1, 1902, February 10, 1903, May 3, 1904, May 17, 1904, as well as the one in issue, April 19, 1904.

It is enough to say of the earlier patents that they show a clamping device differing, to speak in general terms, from the subject-matter of the interference, in that the connecting bolt between the jaws of the former was formed integrally with one of the jaws, while in the latter it is separable from both jaws, but extending through each.

Scott was a mechanic and pattern maker with an inventive talent, who had invented several different devices. Among these was a band fastener, which, having been for a time exploited and sold by him in connection with a business associate named [358]*358Walker, had been, disposed of entirely. Other inventions consisted of “snap flasks,” ball bearings for mowers and reapers, “car movers,” and bumping posts for railway tracks.

Without discussing the evidence, we are content to accept the conclusions of the Patent Office tribunals to the effect that Scott conceived the invention of the issue in May, 1902, but that his experiments therewith did not amount to actual reduction to practice. We are not satisfied, however, with the conclusion of the Examiner, of Interferences that the appellants failed to show an earlier conception than is evidenced by their application for patent, which conclusion the succeeding tribunals adopted without discussing the grounds upon which it was rested. We are compelled to regard those grounds as insufficient. Laas and Sponenburg testified positively that they conceived the invention and had castings made from their model in the Belle City Malleable Iron Company’s works, at Hacine, Wisconsin, on June 29, 1903. In this statement they were supported by the son of Sponenburg and by Bryan, the assistant manager- of said company, Eisher, the foreman in the pattern room, and Blatz, the shipping clerk. These witnesses were neither impeached nor contradicted, and their testimony disclosed no inconsistencies. Bryan has some interest because his company is now manufacturing under appellants’ patent through a license; but the two mechanics have no apparent interest. Moreover, none of the tribunals aforesaid has intimated a doubt of their general truthfulness. The witnesses Sponenburg, Jr., Bryan, Eisher, and Blatz, gave the date of making the castings, but their evidence was not accepted as proving it because they testified from memory alone, and gave no reference to anything to fix the date. The reason for rejecting the date fixed by Laas and/Spon^Bbacg, the elder, is thus given in the decision of the Examiner of Interferences :

“Sponenburg’s testimony shows that, in stating the date of conception of the invention, he depended entirely upon what he was told by the Belle City Malleable Iron Company, and Laas also bases his testimony upon what the records of that company show. These records, as before stated, are not in evidence. It [359]*359does not appear that either Laas or Sponenburg ever saw them, or that Bryan, the secretary and treasurer of the company, referred to them before testifying. It would have been an easy matter for Laas and Sponenburg, or their witness, Bryan, an officer of the Belle .City Malleable Iron Company, to have produced the records of that company. Instead of doing so, they merely make vague references to these records, and do not even testify that they consulted them for the purpose of refreshing their memories before testifying. In Blatch v. Archer, 1 Cowp. 63, 65, referred to and quoted in Kirby v. Tallmadge, 160 U. S. 379, 40 L. ed. 463, 16 Sup. Ct. Rep.
