IMPROVEMENT IN PATTERNS FOR A COUPLER YOKE CASTING ABSTRACT OF THE DISCLOSURE The drag pattern and the cope pattern for a standard AAR coupler yoke are each mounted on a pattern plate to form an oblique angle of about 1° between the mounting surface of the pattern plate and a plane parallel to a longitudinal center plane of the pattern. The patterns each include core print surfaces for establishing the position of one unitary core which is used in a sand mold to form surfaces in the coupler yoke at the front end portion therof. The drag pattern includes pattern surfaces to mold sand to form the surfaces surrounding the draft gear pocket on the upper and lower straps and the rear draft gear seat at the rear end portion of the yoke. The draft gear seat is gen- erally planar and perpendicular with each inside wall of top and bottom straps.
