Test No. 3.—To test repaired triples for re-lease, charge the auxiliary to seventy poundspressure and make a full service reduction oftwenty pounds, or until the auxiliary and cylinderpressure are equal. Place the special cut-outcock in such position that pressure must passthrough the 3-64-inch port, and turn main reser-voir pressure of ninety pounds into the brakepipe. If the triple does not release under theseconditions it should be condemned. Test No. 4.—The triple piston packing ringshould be tested for leakage by blocking the pis-ton in the graduating position, preferably by useof the device shown at A in the accompanyingdiagram, maintaining the brake pipe pressure atseventy pounds. Under these conditions the. -»ine*Hl* It 7* 7ESTIHS aPHt**TfS. pressure in the auxiliary reservoir should notincrease faster than fifteen pounds per minute. Clearance (of Track Gage). The total difference be-tween the gage of the rails and the gage of theexterior bearing surface of the flanges is at pres-ent fixed at about % of an inch, as adopted inJune, 1894. See Fig. 5599. The method of testingwheels for this purpose has been by measuring thedistance in the clear from inside to inside of carwheel. By resolution of the Master Car BuildersAssociation, 1883, the standard distance for flangeswas fixed at 4 ft. 5% in. The limit of % in. eitherway from 4 ft. 5% in. was adopted in 1885. In 1894a standard check gage for mounting wheels wasadopted (see Fig. 5599) which is intended to make the clearance of flanges a fixed distance. The rela-tion
