TROLLEY FRANCHISES IN CHICAGO. At the meeting of the Chicago City Council lastweek, no less than six separate franchises weregranted, giving permits for the construction oftrolley lines on new and existing lines in and nearthe business section of the city. These includedall the horse car lines of the Chicago City RailwayCompany operating in the southern section of thecity, with the exceptiorl of the Indiana avenue. WELDING TRAIN IN SOUTH BROOKLYN. is automatically cut out of action. Connection ismade with the trolley wire by means of a fishingpole having a hook on the end. The main feature of the equipment of thedynamo car is the motor-generator, which may beseen in the illustration, for which we are indebtedtoracci»(cJf?/, in the center of the car. This is acompound wound four-pole machine which runsas a motor from the trolley wire. Its armaturehas but one winding, butithis is connected at dia-metrically opposite points with collector ringsfrom which alteinating currents having 4,400alternations per minute are delivered ; 300 amperesat .500 volts pass normally through this the current is usually supplied from someother trolley line upon which there are at timesabnormal loads, the welder has to contend withvariable electromotive forces which may fall so lowoccasionally as to cause cessation of work. If thevoltage on the line drops below 460, operations
