Opinion

Bland, Judge,

delivered the opinion of the-court:

Appellant has appealed to this court from the decision of the Board of Appeals of the United States Patent Office, affirming that of the Examiner of Interferences, in awarding priority of invention in nine counts, which were copied by the appellee Winsor on July 27,1929, from appellant’s patent, of which count 2 is illustrative and follows:

2. The combination with a tractor, of a frame secured to and extending forwardly from the tractor, a wheeled support for the forward end of the frame, a grader blade adjustably carried by the frame rearwardly of the sup[1108]*1108port, an operator’s station, and controls extending from said wheeled support and from said grader blade to within reach of the operator at said station.

The senior party, Ronning Machinery Company, which will, for brevity, be hereinafter referred to as Ronning, is involved upon an application for reissue of patent No. 1,706,256, issued March 19, 1929, upon an application filed March 12, 1921. The junior party’s application was filed April 7, 1923. The two applications involved were copending, and Winsor, being the junior party, was under the burden of establishing his priority by a preponderance of the evidence.

The interference relates to the structure of a grader designed for one-man operation and consists of a combination of a tractor, with the front wheels omitted, and an attached framework extending along the sides of the tractor and connected to the rear thereof, which frame extends forward and is supported by steering wheels. Between the steering wheels and the tractor is suspended the grader blade. A means attached to the frame is provided for lowering, raising and adjusting the blade. The action of the blade and the steering of the grader is controlled by one man who is stationed on a platform about midway between the front and the rear of the grader.

Ronning made no attempt to prove a date of conception and reduction to practice prior to March 12, 1921, and is restricted to that date for conception and reduction to practice.

Winsor claims conception in 1918 and offered considerable evidence in support thereof, but the facts of record chiefly relied upon by Winsor as showing his conception and reduction to practice occurred in the year 1919, when Winsor claims he reduced the invention to practice by building a grader and thoroughly testing it. The sufficiency of the proofs of reduction to practice as early as 1919 on the part of Winsor is severely criticized here, as it was in other interferences and actions relating to the same general subject matter.

Appellant argues two main questions here, first, that the record does not establish that Winsor conceived and reduced his invention to practice in 1919, and that he has not, therefore, shown that he was the first inventor in fact, and that his long delay in claiming the invention after his alleged reduction to practice is persuasive, under the well-settled rule, that what he accomplished amounted to nothing more than an abandoned experiment; second, that even if Winsor did complete-his-invention in'1919, he-is-estopped from claiming the same in this interference. The estoppel is grounded upon three different theories: (a) that Winsor conceded priority of the subject matter of these counts in an interference proceeding in Canada; (b) that Winsor delayed too long before claiming the invention, knowing at the time that Ronning claimed the invention and that [1109]*1109Winsor’s conduct, hereinafter discussed, misled Eonning to his great injury; (c) that Winsor failed to copy the claims of Eonning’s patent No. 1,658,354 within two years of its issue date.

We will first consider the facts of record relating to Winsor’s conception and reduction to practice. The record is voluminous and the Examiner of Interferences and the board have discussed it in great detail, and in view of the fact that we agree with the Examiner of Interferences and the board in their understanding of what the evidence shows and the effect to be given it, it will not be necessary for us to comment extensively on certain unimportant features of the same.

Winsor testified that he was a mechanic with considerable experience in working on automobiles, motor trucks, tractors and internal combustion engines; that he had been interested in one-man control and had applied the same to a passenger boat which he operated on Walloon Lake; that during a part of the years 1917 and 1918 he was in partnership with a party by the name of MacLean in Detroit, which partnership was dissolved in February, 1918; that he then went to Walloon Lake to cut and store ice; that in January, 1918, he made a drawing (Winsor Exhibit C) and explained the same to MacLean. This drawing discloses the structure involved in the counts at bar. Winsor stated that he explained the one-man tractor grader and showed the drawing to witnesses Hewitt and Williams in February, 1918, and that he talked over the tractor grader with one Eobnolte, who was manager of the Quinlan Eanch or farm located near Pellston, Michigan, and that Eobnolte gave him permission to use the Cleveland farm tractor which Eobnolte had bought through Winsor while Winsor was working for the Homer Sly Auto Company.

MacLean’s, Williams’ and Hewitt’s testimony corroborates Winsor as to the disclosure made to them in the spring of 1918. They testified that they saw the drawing (Winsor Exhibit C).

The tribunals below did not regard it as necessary to determine whether or not the evidence as to Winsor’s 1918 activities should be regarded as sufficient to prove conception, since they concluded that Winsor’s proof of what he did in June, 1919, was satisfactory proof of conception and reduction to practice; that the happenings in the Spring of 1918 might be regarded as throwing some light upon the June, 1919, events, and that all these alleged happenings occurred before March 12, 1921, which was the date to which Eonning was restricted.

Winsor testified that in June, 1919, he' was in the employ of the Homer Sly Auto Company, Petoskey, Michigan, and that during that month he constructed a one-man tractor grader, the tractor of which he borrowed from Eobnolte, the manager of the Quinlan [1110]*1110Ranch; that he used a four-wheeled horse drawn road grader belonging to the township, and that one McDermott, a blacksmith in Petoskey, made some of the parts. Winsor states that Robnolte, Eldred, McDermott and Williams, as well as other persons, saw the completed machine. Winsor’s Exhibit D is a drawing made subsequent to that date but which, according' to the witnesses, shows the kind of machine which was built at that time. Winsor states that he and Robnolte operated the tractor grader on a section line dirt highway adjacent the Quinlan Ranch to clean up the ditches and round up the road. Winsor states that the operation was a complete success. After being operated parts of three or four days, the structure was dismantled and the tractor returned to Robnolte and the grader to the township. Each night, after operating the grader, it was necessary to disassemble it in order that the toactor might be ready for use on the ranch.

Robnolte completely corroborates Winsor, and we have observed no particular in which his testimony was in any way weakened.
