The Gilman-Brown emergency knuckle, as shownby Fig. 1, will go into ninety-five per cent, of the drawbars in service and make a rigid coupler, into whichany automatic coupler will lock securely if in goodorder. By simply removing or raising the lockingpin or locking parts and inserting this emergencyknuckle, replacing the knuckle pin, which is seldominjured, a safe and complete connection is Fig. Emergency Knuckle. The chances are enormously in favor of the emer-gency being safely and satisfactorily met if there isone of these knuckles close at hand. It is essentially a repair tool which could well beconsidered part of the equipment of every freightengine, switch engine and way car, as it is a practicaland economical insurance against delay on the roadin consequence of defective knuckle or locking parts. CAST STEEL FOR LOCOMOTIVE PARTS. The use of cast steel in place of wrought or cast ironis of quite modern practice. The object accomplishedthereby is a reduction of cost over wrought iron and alightening and strengthening of parts formerly con-structed of cast iron. The first locomotive parts to be made of cast steelwere the centers of driving wheels. As cast steel isordinarily considered about three times as strong ascast iron, the section of all parts of the wheel center
