ROBB, Associate Justice.
Appeal from a decision of an Assistant Commissioner of Patents in an interference proceeding awarding priority to the junior party Gile. The invention relates to a plow tractor and is expressed in a single count, as follows:.
“In a plow tractor, the combination of a pair of coaxial traction wheels at the sides of the tractor respectively, a single front steering wheel substantially aligned longitudinally with one of the traction wheels, said longitudinally aligned steering and traction wheels being disposed at the furrow side of the tractor and adapted to travel in the same furrow, a frame supported by said traction and steering wheels, differential gearing between the traction wheels and whereby both will be' driven, and a motor mounted on the frame and connected to drive said gearing, said single front wheel when traveling *995in a furrow, acting to automatically steer the tractor; said gearing causing the traction wheels to be driven at relatively different speeds in steering the tractor responsively to tlie front furrow wheel.”
In the summer o£ 1914 Gile built a tractor at Eudington, Mich., which we will assume embodied the issue, and in October of that year this tractor was taken to a farm near Scottsville, Mich., and there tested. In November, following, it was taken'back to Eudington, and, so far as the evidence discloses was not used thereafter, but found its way to a neighboring ball park, where it remained until the spring, of 1916, when it was discovered by representatives of licensees of Hartsongli, whose attention was attracted to it by its resemblance to the Hartsough tractor their concern was manufacturing under license. The Examiner of Interferences found, and we concur in the finding, that Gile was inspired to apply for a patent by representations then made to him. After the construction and test of this machine, it apparently passed out of his mind, for he directed his attention to the construction of another machine, which was completed in the summer of 1916, and upon which he almost immediately applied for a patent. After a patent had inadvertently issued to Gile upon the application induced ,by the licensees of Hartsough, those licensees ceased paying Hartsough royalties, but continued to manufacture the tractor under a license from the assignees of the Gile patent.
[1, 2] When Hartsough’s application was filed in July 21, 1915, he not only liad perfected his machine, but had placed the same on the market, where it was very favorably received. Gile, whose concern manufactured and sold to Hartsough motors for his tractor, and who must have known of the tractor’s success, did nothing about asserting a claim to tlie invention, as we have seen, until after the incident to which we have alluded. The testimony relating to the character and sufficiency of the test of the Gile tractor in October of 1914 was taken in May of 1917, or more than 2% years after the test. The testimony tended to show that tlie tractor did “very good work,” or, as Gile himself testified, “Well, we considered the work very good.” The testimony not only is lacking in detail, but is so inconsistent with what followed, as to cause us to adopt the finding of the Examiner of Interferences that it falls short of proving reduction to practice. As the Circuit Court of Appeals observed-in Griswold v. Harker, 62 Fed. 389, 10 C. C. A. 435, “Actions often speak louder, and frequently more truthfully, than words.” It is inconceivable that Gile, an intelligent man, abundantly able apparently, to take advantage of and protect and promote any invention he should make, and who admittedly was endeavoring to evolve a successful tractor, would have acted as he did, had the test of this tractor been even measurably successful. When the testimony was taken tlie tractor was in existence, and apparently as callable of being operated as in 1914, and yet it was not operated. While it is not incumbent upon a party, after satisfactorily proving reduction to practice, again to operate his device, in a case of this sort, where there is a serious question as to the success of a former test, tlie most satisfactory way to settle the question, it occurs to us, *996would be again to test the machine. There are other circumstances all tending in the same direction to which the Examiner of Interferences alluded in his opinion, but which need not be repeated here.
[3] This court has uniformly ruled that where, as here, a machine is constructed, tested, put aside, and apparently forgotten, and another party in good faith enters the field and constructs a similar machine, puts it upon the market, and applies for a patent, the first party, who slumbered upon his rights, must have very clear and convincing evidence that the test of his machine fully complied with the requirements as to reduction to practice, and that if he fails to sustain that burden the test will be regarded as a mere abandoned experiment, and priority awarded the party through whose efforts the public received the invention. Warner v. Smith, 13 App. D. C. 111; Adams v. Murphy, 18 App. D. C. 172; Howard v. Hey, 18 App. D. C. 142; Quist v. Ostrom, 23 App. D. C. 69; Gordon v. Wentworth, 31 App. D. C. 150; Moore v. Hewitt, 31 App. D. C. 577; Collis v. Quenzer, 38 App. D. C. 481.
We rule, therefore, that Gile has not sustained the burden of proof in this case, and, as he clearfy-was lacking in diligence, the decision is reversed, and priority awarded Hartsough.
Reversed.
