Not illustrated. 1920 edition. Excerpt: ... for steel railway-cars and it appears that B. started out to invent such an underframe, while McK. started to invent a light-weight steel box-car, and that in January or February, 1906, prior to the date that B. entered the field, McK. had ordered materials for the car, but that owing to delay in receiving such material actual construction of the car was not begun until July, that the underframe was completed in September, but owing to delay in securing materials for portions of the superstructure the car was not completed until December, 1906, when it was subjected to a severe test and put into service, Held that McK., who was the first to conceive the invention, was not lacking in diligence in reducing it to practice and that priority was properly awarded to him.
