Railway and locomotive engineering : a practical journal of railway motive power and rolling stock . w supplied to protectthe controlling valve under the benchfrom moisture and other foreign sub-stance. The top of the bench is fittedwith a steel plate in which openingsare made to receive the flanges of thetriple valve, thereby providing a visearrangement for holding the triple by of. This is a most important subject;for, no matter how well the remainder ofthe brake apparatus is maintained, if thebrake cylinder leaks the brake is ineffi-cient. The pump is the beginning of the brakesystem and, so far as the air pressure isconcerned, the brake cylinder is the and tender brakes are daily wherethey can be tested and repaired, yet brakecylinder leakage is probably the mostcommon and the most serious defect, atleast with the former. Some roads pro-vide a plugged tee by which a test gaugecan easily and quickly be attached, anexcellent provision that should be uni-versal. But. as Mr. Hovvarth says, the carbrake has no convenient means for usinga gauge. With the large number of such. NEW TRIPLE VALVE TESTING MACHINE. VIEW SHOWING QVICK CLAMPING DEVICES AND NEW VALVE K. ing arrangement which fastens thevalve to its stand consists of two ec-centric handles working in horizontalplane and otherwise similar to thoseon the older machine which worked ina vertical plane. The hose is also at-tached to the triple by a quick clamp-ing device, instead of being screwed onwith a wrench. It will be also observedthat the arrangement for correctly andaccurately placing the piston and slidevalve of the triple at lap position, forthe packing ring test, is made muchsimpler and better. By special ar-rangement, on this attachment, any ofthe triple valves may be placed at lapposition accurately and correctly bymerely turning a connection on thestem for that certain triple valve. Thegreater improvement in this device, merely placing it on the bench. Suit-able pins are also supplied in t
