The piston is at the beginning of its■itroke and the push-rod is connected tothe triangular lever B in such a mannerthat, as it moves ahead by the action of thepiston the outer end of the triangular which the lever G is connected, travelsvery much more rapidly than the end ofthe push-rod, but that as it moves forwardits speed decreases and the leverage of thepush-rod increases until finally the pinconnection between the links D and Fdrops into the socket Si of the triangular. Plan A BR.\KE PRESSURE RECUL.\TIXG DEVICE. Locvmotife Emjiit^cfhttj part of the stroke of the piston gives avery rapid motion to the cylinder lever,thus taking up the brake-shoe slack quick-ly ; as further travel of the piston gives amuch slower motion to the cylinder lever,the braking power is greatly increasedover that of the initial travel. The second device prevents the brakingpressure on the shoes increasing suffi-ciently to skid the wheels. This is accom-plished by making a relief to the brake-shoe pressure by slightly lifting the endsof the car and permitting the compressedair in reservoir and cylinder to expand,which is done by introducing between thetruck and car body a weighing lever andbent lever, to w-liich latter the brake leversare connected, and through the movementof which, by the weighing of the car andits load, the braking pressure is main-tained at a certain predetermined maxi
