Boycott - Clayton Act - In Duplex Printing Press Company v. Deering et al. (January 3, 192I) 41 S. Ct. 172, the facts were: The plaintiff, a Michigan corporation, manufactures at Battle Creek, and sells throughout the United States, especially in and around New York City, and abroad, very large, heavy and complicated newspaper printing presses. Purchasers furnish workmen, but ordinary mechanics alone are not competent to do this, and so they are supervised by specially skilled machinists furnished by plaintiffs. The plaintiffs have always operated on the "open shop" plan, without discrimination against union or non-union labor, either at its factory or at the place of installation of presses, but have not observed the eight-hour day nor the union scale of wages.
