The platformknees are reinforced with angle-iron, and angle-iron bumpersof Brill patented type protect and strengthen the platforms.The cars are mounted on the Brill 27-F E-i trucks, with 33-in.wheels, and equipped with four 38-hp motors per car. blown-out fuse is another serious objection to this method. The automatic oil-car circuit breaker, manufactured by theHartman Circuit Breaker Company, of Mansfield, Ohio, isdesigned to take the place of the fuse block and hood-switch onthe car. It operates automatically upon an overload, and, atthe same time, can be thrown by hand as readily as the ordinaryhood-switch. It is said to be practically noiseless in operation—only a faint click being heard when the breaker opens evenon the severest overload. The manufacturer believes that thisfeature will be appreciated where car circuit breakers withmagnetic blow-out have been used.The switch contacts are of the laminated type, to ensure. Emperor William has telegraphed his congratulations to thecompany engaged in the electrical experiments on the Marien-felde-Zossen Railroad, on attaining a speed of 125 4-5 m. p. h. EXTERIOR OF .COLUMBUS CAR perfect electrical connection, and also to prevent freezing ofthe switch at critical periods. The arc is ruptured in oil uponauxiliary contacts. Of these there are four, connected in series, giving a quadruple break. The circuit breaker shown in Fig. 1 has a capacity for con-tinuous duty of 400 amps., and any desired overload adjustmentcan be secured from 100 amps, to 900 amps. Fig. 2 represents the Hartman circuit breaker mounted forswitchboard use. This circuit breaker is especially adaptedfor the protection of railway feeder circuits where the con-ditions are peculiarly exacting. The breaker cannot be thrownin while an overload exists, and thus dispenses with the neces-sity for using an additional switch on the circuit. As a handswitch it is stated
