A goodconnection between the trolley wire on the approachesand the T iron on the draw is guaranteed at all times bymeans of rollers on copper tubes, and a spring whichkeeps the connector firmly pressed upward.

No. 0000 hard-drawn copper trolley wire is used, except on the draw, andthe ends of the wire are anchored in the manner shownat the end of each approach. When a car is about toenter the draw, the trolley wheel passes along the over-head wire until the flange of the wheel strikes the metalconnector, which is shown in the cut. As is shown by this connector is furnished with flaring ends, so as tocatch and guide the trolley wheel. The wheel rides onits flange over the connector until the car is on the draw,
