Cyclopedia of locomotive engineering, with examination questions and answers; a practical manual on the construction care and management of modern locomotives . ng the Bourdontube springs and their mechanism. It will be observedthat the tube springs are attached to the socket and tothe tips, to which the lever mechanism is connectedin a new way. The method prac-ticed is to have theseattachments of thetube springs made bymeans of solder orother metal of low-fusing point, and,while this may besafe in all low-pres-sure gauges, orwhere in their loca-tion in use they arenot subjected togreat heat, yet it ishazardous wherehigh pressures of steam are to be measured by them,especially where there is liability of the admission ofsuch steam into the tube springs. In such case thesoldering material may soften, and under the highpressure be forced out, causing a leak and the destruc-tion of the gauge. In the Crosby improved locomotive pressure gauge,the tube springs are connected at each end withtheir respective parts by screw threads, withoutthe use of any soldering material whatever, thus in-suring tight joints under all conditions of heat Figure 179Crosby Duplex Gauge f INJECTORS, STEAM GAUGES, ETC. 2*9 In addition to the improved Bourdon tube spnngsso employed, careful attention has been given to thelever mechanism which transmits the free movementsof these Bourdon tube springs to the index. Theyhave been designed and constructed not only to con-vey the full movement of the tube springs, but so thatthey may be renewed without difficulty in case ofrepairs or reconstruction. American Locomotive Gauge, with non-corrosive move-ment, Figs. 181 and 182. It is constructed of metalsof superior quality, to withstand the constant vibrationto which it is subjected. The spring is made of veryheavy seamless drawn tube of superior quality. Theconnections are made of hard phosphor bronze. Themovement is made with a wide faced sector which willoutwear three of the ordinary se
