. The Street railway journal . FIG. 3.—POWER FACTOR INDICATOR. SEMI-CONVERTIBLE CAR, WITH DETROIT PLATFORM, FOR TOLEDO dial type. The indications of the instrument give the factor bywhich the volt-amperes should be multiplied to obtain thetrue watts. The standard portable alternating-current ammeter, shownin Fig. 4, is provided with a separate series transformer havingfour ranges in one case. By this means one indicating instru-ment can serve to measure the following maximum currents,5 amps., 25 amps., 100 amps, and 400 amps. This equipmentcan be used on a circuit of 5000 volts or 6000 volts,

This equipmentcan be used on a circuit of 5000 volts or 6000 volts, and it isstated that the portable instrument is perfectly safe to handle. This firm has also designed a portable polyphase wattmeterfor two-phase or three-phase circuits. By using suitable setsof transformers with this instrument it can be made to indicate. FIG. 4.—PORTABLE ALTERNATING-CURRENT AMMETER directly the total output of a three-phase circuit even whenthe loads are not equally balanced between the phases. Tie Stark, Ohio, Electric Railway Company has bad all itsmotormen and conductors sworn in as special officers in Mahon-ing and Stark Counties. They will have authority not only onthe companys property but will have power to pursue and cap-ture any one who attempts- to escape. Failure to suppress law-lessness renders the employee liable to a fine of from $5 to $25. in relation to the conditions found in Toledo. The cars runin one direction, and therefore the entrance is from one platforms are used at the rear for the purpose ofloading and unloading from that end only, the pipe rail (shownin the illustration) divides the platform and keeps the entranceclear. The illustration of the interior of one of the cars showsthe seating arrangement, with longitudinal seats at the rear, toprevent crowding at the door. Unfortun
