Show JL New Electrio Hallway. It aims at connecting a moving car with an electrio conductor buried be-Death be-Death the roadbed without the use of an open slot. To effect this there is laid in the center of the track a crenelated contact con-tact plate or rail in short sections. This will be only half an inch in width on the surface and will be quite different in its effect upon vehicles from the ordinary car rail; wheels will cross it without difficulty dif-ficulty at any angle, as they cannot slide 1 along it for more than a few inches. S Horses will also find a good foothold B upon it. The short sections of the plate are entirely en-tirely disconnected from each other, each piece being coupled by a wire to theelec-tric theelec-tric conductor beneath. In this wire is an automatic switch which makes circuit between the section and the conductor con-ductor as the car comes over it and breaks the connection when the car lias passed. Only three sections are ever connected with the car at one time, and generally there are only two. A strong wire brush on the car rubs a!on the sections sec-tions and conveys the currents from them to the electrio motor, whence it flows to the rails and to earth. I The automatio switch is simplicity it-self it-self and consists merely of an electro-! electro-! magnet, an armature and two contact ; pieces. " Supposing that the car brush is ; in contact with one of the sections, the i current will flow from the main con- ductor across ono contact to the arma-I arma-I ture. throuch the armature to a second I contact, thence through the magnet coils to the section and the motor, and as the ti car proceeds it successively takes sec- tions into circuit and drops them out.
