DRAFT DIGGINGThe draft rigging for the steel cars involves interesting fea-tures, as shown in the accompanying drawing. The arrange-ment of apparatus provides for new improved type of auto- matic coupler, built by the W. T. Van Dorn Company, which isthe standard of the Interborough Company. The coupler headis attached to the draw-bar through the Van Dorn standardtype of spring buffer casting, to the top of which is riveted themain draw-bar, 8 ins. x il/2 ins. in section. Limitations of con-struction prevented this main draw-bar being carried throughto the king bolt, so that a special form of auxiliary bolster con-struction was necessary to permit the desired radial movement. VIEW TAKEN FROM PIT BENEATH ONE OF TliJi STEEL CARS, SHOWING ARRANGEMENT OF APPARATUS or swing for the coupler. An auxiliary draw-bar, 8 ins. x 2 section, is carried from the opening in the main body bolsterfiller casting forward a distance of 19 ins., where it ends in aspecial type of auxiliary bolster, bolted in between the centersills, as shown. This auxiliary draw-bar is forged in clevisshape, into which the end of the main draw-bar is secured byan auxiliary king bolt, 2^ ins. in diameter. This provides a main draw-liar radius of 6 ft. 1 in., whilea transverse swing movement of the coupler of 36 ins. is there-by secured. The weight of the main draw-liar is carried by aspecial sector plate above the spring buffer casting, which as-sists in taking care of the buffing strains from the draft rig-ging. The main sector plate upon which the draw-head itselfslides, is built up of a 4-in. angle, curved to correspond withthe movement of the draw-head, a
