Opinion

GRAham, Presiding Judge,

delivered the opinion of the court:

An interference was declared in the United States Patent Office between the application of Elmer C. Long, filed February 13, 1928, the application of Bay E. Day, filed March 1, 1926, and the application of Gordon E. Evans, filed January 30,1926. The subject matter of the interference is described sufficiently for the purposes of this case by count 5, which is as follows:

5. A piston embodying a cup shaped.bead, two diametrically opposite spaced apart supports extending downwardly from the bottom of said bead, two wrist pin bosses secured to said supports, two slipper sections separate from said bead and forming thrust faces for said piston, and two struts rigidly connected with and diverging from the medial portion of each slipper section and connected with the two wrist pin bosses, said struts being carried by the head only through said supports.

Each of the parties filed a preliminary statement and took testimony. The party Evans, through his assignee, The Cleveland Trust Company, alleged conception and disclosure of the subject matter of the invention on or about August 7, 1925, and reduction to practice as of December 3, 1925. The part}*- Long, in his preliminary statement, alleged conception on or about the first day of April, 1921, and reduction to practice as of July 15, 1921. The party Day, in his preliminary statement, alleged conception of the subject matter of counts 5, 6, and 7, in 1920, and a reduction to practice of the same in the same year. As to counts 1, 2, 3, and 4 of the interference, February, 1922, was alleged as the date of conception, and a reduction to practice during the sunimer of 1926.

Both the examiner and the Board of Appeals awarded priority to the party Evans, the senior party. There is. some difference of opinion between these tribunals as to various facts, but, in essential particulars, the conclusions of the examiner and the Board of Appeals are in harmony.

The parties Long and Day have appealed. The record made by the parties is very voluminous, and has required much time for its consideration. No questions of law are presented, and the matter rests entirely upon the proofs which the parties have offered as to dates which should be awarded them for conception and reduction to practice, respectively. In what we have to say we shall discuss the case which each party has made, in turn.

The Board of Appeals awarded the party Evans a date of conception of November 16, 1925, and a constructive reduction to prac[1083]*1083tice by the filing of his application herein involved as of January 30, 1926. In coming to this conclusion, the board discusses Exhibit 24 of Evans, which was an incomplete piston, lacking the head and some other features. There was some difference of opinion between the Examiner of Interferences and the Board of Appeals upon the matter as to whether this exhibit was a sufficient proof of conception. The board was of the opinion it was not, and we find ourselves in agreement with that conclusion. However, other pistons were made up according to certain drawings which were known as Exhibits 12 and 12 a, and were tested, the test being completed on November 28, 1925. This date, November 16, 1925, therefore, was given to the party Evans as a date of conception, and, inasmuch as the pistons then made and tested seem to have embodied all the features of the subject matter of the interference here, we agree with the board that conception is established, as of that date, by the party Evans. We are also of opinion that no weight may be given the fact that the party Evans did not testify. The record' plainly shows that an effort was made to locate him, and that his whereabouts could not be ascertained. After Evans’ date of conception, he proceeded with celerity to the filing of his application.

As to the party Long, the Board of Appeals was of the opinion that the counts of the interference would not read upon Long’s earlier application, serial 602,660, filed November 22, 1922, and which is alluded to by appellant Long as his Case M. The disclosure in this earlier case was of a piston in which the struts supported the slipper sections of the skirt not in the manner shown by the application here involved, but in which the support was made by attachments of the struts near the ends of the segments of the skirt and not at intermediate points thereof; in other words, the strucure as shown m the Case M pistons was, as the board has termed it, an “ hour glass configuration.” We find no error in this conclusion. The structures seem to be very different in principle.

The board further held that the party Long had failed to establish conception by the drawing of plans and the completion of pistons for the Holmes car in 1921, as alleged by him. However, the board was of opinion that Long had established sufficient facts to show a conception of the subject matter of the interference in connection with certain pistons manufactured and sent to the Paige Motor Company in August, 1925. The board was of opinion, however, that there was not sufficient evidence to establish a reduction to practice of these Paige pistons. The Long application here in issue was filed on February 13, 1928, and the board was of opinion that, from the date of conception in August, 1925, until the date of filing, there was insufficient activity on the part of the party Long “ to overcome the show[1084]*1084ing by Evans.” Long, therefore, was given a date of August, 1925, for conception, and of February 13, 1928, for reduction to practice.

Long’s claim to conception in 1921 depends largely upon the testimony of himself, Wilfred D. Fink, It. Gerald Ralls, Edward A. Heuman, and Arthur Holmes. To understand the exact situation, it is necessary to know something of the work which the party Long was doing. He was attempting to build up a business in the manufacture and sale of pistons, having spent the principal part of his life in this business. From April, 1920, until about the first of J une, 1923, he was located at 4834 Beaubien Street, in Detroit, Michigan. At this and his other business locations he solicited and obtained business in making cylinders for many makes of cars. Drawings were made up, from time to time, of various models of pistons, including improvements and changes of sizes and construction. Constant experimentation was going on along these lines. Drawings, as they were made, were numbered according to the particular number which was given some type of piston. These numbers were not taken numerically, but seem to have been haphazard in their selection, so that numbers did not continue chronologically. The drawings were not dated, and, hence, such drawings as were introduced by the party Long depend for their dates upon the memory of witnesses. As a consequence, the evidence furnished by such drawings is unsatisfactory and inconclusive. The witnesses were hazy in their recollection, and did not, by their testimony, clearly establish facts upon which a fixed determination with respect thereto could be readily and conclusively made. For instance, the witness Fink, who was employed by the party Long, and upon whose testimony Long largely relies, gives testimony as to the use of certain pistons which were claimed to be of the type here involved, but the exact character of which is, because of the absence of clear and convincing proof of dates, not satisfactorily shown.
