The construction, manner of attaching and oper-ation of this device may be described as follows: Theapparatus is interchangeable, there being no rightsand lefts. The coupling head consists of a castingwith openings on its face to receive the registeringgaskets, and a coupling spring riveted thereto, asshown on the plan view (Fig. 1), On the elevation 557 558 LOCOMOTIVE APPLIANCES. view (Fig. 2) is shown a cast-steel bracket rivetedto the under side of the drawbar, to which a slot-ted hanger, in which the coupling spring rests, anda chain arm to support the coupling head, arebolted. The gaskets are so placed in the head thatneither is touched by tlie opposite one until thecou]3ling is made. This protection is effected bya tongue ^nd groove, on which tongue the facerides until the gaskets are in position to register,when the tongue drops into the groove.
