The Lehigh Valley Railroad has decided upon the .policyof applying steel underframes to all freight cars passing tliroughits shops hereafter for general repairs. A striking example of development in connection with theindispensable bolt cutter is shown in the accompanying illustra-tion which represents the latest output in that line of the Wileyand Russell Mfg. Co of Greenfield, Mass. This machine issomething entirely new, and combines the features of an opening-die bolt cutter, nut tapper, pipe-threader and cutting-off machine,with the addition of electric motor drive. The drive is attachedto a standard machine and forms the feature of main interest. In the arrangement of the drive it will be noted that abracket is fitted and bolted to the bed on which the motor shelf. APPLICATION OF MOTOR DRIVE TO BOLT CUTTER. is secured. This shaft is hinged at the back and has finishedprojecting lugs which rest on the cam shaft operated by thelever (A). By this sufificient tension can be kept on the beltat all times and the belt can be slackened off when desired toshift it from one step to another on the cone pulley. After thebelt is tightened the cam shaft is locked with a binder. Thelever (B) in front of the motor controls the clutch in thelarge spur gear so that the bolt cutter can be stopped independ-ently of the motor. The latter, which is of two horsepower, isconstant speed and back geared, and is fitted with a rawhidedriving pinion. The motors are furnished for direct or alternat-ing current, reversing or non-reversing. It is quite apparent from a study of the design that the entirearrangement is strongly and carefully fitted, the machine beingguaranteed in fact to cut bolts and pipe to two inches in diam-eter. Th
