The working value of any truck, fromlioth operating and maintenance stand-ards, rests in its stability under ratedload with inherent flexibility to meetall operating conditions without dis-tortion of parts, and free equalization,Ijntli transversely and longitudinally, toinsure correct alignment and contact ofjiiunial bearings and practically uniformwheel loads. Important features alsoare the minimizing of the number ofseparate or bolted parts, as well as theaccessibility of parts for adjustmentof height, or changing of wheels andaxles, and other parts. The quality of free Hexibility withoutdistortion provided by Fox trucks restsin the spring support for frame whichimposes the weight centrally of the axle. SWING-MOTION TYPE OF FOX TRUCK FOR TENDERS. There are three distinct types. Theordinary freight car type, withoutbolster, is essentially a four-piece con-struction, consisting of two side-framesconnected by two transoms which carrythe center-plate and springs are used over the jour-nal boxes to carry the weight, cushionagainst shocks and provide is the simplest and cheapest form. The type used on locomotive tendersis similar to the ordinary freight cartruck, but is provided with stirrup-hangers from transoms which carrysprings, either helical or elliptic, andseats supporting an independent play is provided at each end ofthe bolster to suit requirements. The swing-motion type for cars inlocomotive tenders are provided witha swing-motion device, either pin orlug supported, with long hangers con- same ratio of pressure.
