Thefloating wedge being slightly shorter thanthe distance between the binder and topof the pedestal jaw, the effect is that thefloating wedge will slightly relieve theadjusting wedge, completely preventingany tendency to sticking or seizing ofthe driving box, thereby eliminating anyneed of adjustment while the locomotiveis running, and, consequently, reducingto a minimum the wear and tear of theworking parts of the locomotive. The New Special Westinghouse Fifty-Hour Air Strainer. The new special Fifty-Four air com-pressor strainer recently brought out bythe Westinghouse Air Brake Companyembodies features called for by modern. AIR STRAINER. service conditions that were not existentnor necessary in the older type. De-mands of the modern heavy locomotiveand car equipment, also longer trains,require a much greater air supply in thesame time than formerly. This has beenadequately met by the greater size and(a[iacity of the compressor, also by in-creased efficiency at each step of com- pressor development, and the develop-ment and modification of the air strainerto keep pace with the heavier demandsof the modern conditions now naturallyfollows. Earlier efforts were made fromtime to time in this direction, but theydid not result in securing in full measurethe improvement deserved and the newFifty-Four is presented to meet thedemands of heavy compressor service. The prime requirements of such a com-pressor strainer are, proper capacity topresent to the compressor a large volumeof air at low vacuum
