All that now remains is topush the carriage along its track until the ram has forcedthe armature out. The armature will then be supportedat one end by the motor shell and at the other end by avertical frame on the carriage. In this position desired. Hamburg Shops—Glazed Side Construction in Mill Room repairs can be conveniently made, or the crane can be usedto transport the armature elsewhere. The armature is re-stored to place merely by pushing the carriage in the oppo-site direction. The miscellaneous section of the overhaul shop con-tains a gas-ring equipment for expanding tires when offthe wheels, but as yet no work of this kind has been neces-sary. Up to Feb. 15, 1913. the earlier steel-tired wheelshad run 100,000 km (62,000 miles) without any replace-ment whatsoever. Gas is also used here for the solderingof armature leads and similar work. The machine shopcontains the usual tools to permit the management to carryon practically every kind of maintenance work in additionto a certain amount of manufacturing if desirable. These Hamburg Shops—Ram for Removing Armature tools include two wheel lathes, shaper, grinder, buffer,drills, etc. Most of them are driven from independentthree-phase motors through overhead belting.
