June 30, 1894. WALKEE COMPAMYS ELECTEIC EAILWAYmOTOES. During the last two or three years since electricrailway motors have reached a high state of per-fection, a vast amount of attention has been de-voted to the problem of overcoming the deteriora-tion of the track. As traffic has increased and ascars have been built more heavily and have track, is still opposed by the mass of the motor,whose inertia is very considerable and the conse-quent inertia blow on the rails is not avoided. The illustrations herewith presented show theingenious and novel, yet simple, method by whichthe elimination of both these effects is arcom-plished in the system under consideration. Themotor is trunioned by its bearing cases and swings. very light weight for its output has made possiblea very great saving in the cost of maintenance ofway, not to mention the increased lifeof the motoritself, by r>ason of the reduciion of destructive vi-bration and shock«. Another feature of this system well worth men-tioning is the disposition of the bearings. Theseare made extra long and large, and their insideends are removed about three inches from theopenings in the housing, which is only just largeenough to allow a small clearance for the shaft inpassing through. In this three inch space thereare the thrust collars; and all the grease that isforced out between the ends of the bearmgs andthese collars is thrown by the centrifugal actionagamst the walls of the recess, from whence it findsits way through a large opening at the bottom totheground. Thus no oil or grease can possibly getto the commutator or windings. The .shaft is so constructed that in case of wearof the journals it can be withdrawn fr
