An interference was declared between the application of Samuel R. Terry and a patent granted to Rosen and Fischel. The patent issued before the application was filed, and there-, fore the burden of establishing his case beyond a reasonable doubt rests on Terry. The patent involved relates to a locking mechanism for an automobile, and is expressed in two counts. We give count 1:

The combination of a steering shaft having its upper end provided with a reduced extension and a projecting threaded stud, a journal collar mounted on said reduced extension and provided with a bolt socket and with a circumferential groove, a nut securing said journal collar to said shaft, a steering wheel having á spider provided with a hub mounted on said journal collar and protecting said nut, a pin in said hub engaging said circumferential groove, and a lock mounted in said spider and equipped with a bolt adapted to engage said socket.

*1017The question involved is one of originality, which depends for its solution upon matters of fact. Each of the three tribunals of the Patent Office made a careful analysis of the testimony. According to the Examiner of Interferences, Terry “established his right to the invention beyond any reasonable doubt.” The Examiners in Chief said “that there is absolutely no corroboration of the contention of Rosen and Fischel that they had any part in the invention of the matter in issue,” and the Commissioner concurred in this view. Our study of the record convinces us that these conclusions are correct, and therefore the action of the Commissioner is affirmed.

Affirmed.
