The illustrations show the signal hox in place upon abracket, though it may be placed upon a span wire whendesirable. The liox, Fig. i, is of iron with a short project-ing arm, which is struck by a pin erected upon the top ofthe car, and is thus driven to one side in the direction inwhich the car is advancing. This action throws into per-manent electrical connection the trolley wire and the project-insj arm of the next liox which is located at the fartlier vml. of the block or running section. »\ftcr the car lias passed,the arm of the signal box returns to its vertical position. The photophonc box, Fig. 2, is placed ii])on tlie car,either overhead, or upon the sash in front of the niotorman,and the binding posts are connected, one with the pin on thetop of the car and the other with the gearing beneath thecar, thus groun(hug that side of the liox. If now the car has passcil the box as shown in lig. 3, andhas driven the arm to one side, thearm will return to its vertical posi-tion hut the connection between thetrolley wire at the box and the pro-jecting arm at the next box willremain. If a car attempt to leavethe switch ahead, its contact pinwill strike the arm on the box, al-lowing current to flow through thi-])hotophone box, ringing the bell inthe box and causing the 1;um|> to 1 11 1 1 1 • burn. .\fter the ear has nm through tin- block lo its end iN pin\N ill evidently strike the arm therein the opposite directionfrom that in which th
