HARP WITHOUT WHEEL sleeves, switches, circuit breakers, block signals, and otherobstructions in the transmission wires, the harp is forceddown against the action of the buffer springs and instead ofthe pole being thrown down and the wheel leaving the wire,the springs hold the wheel tight to the wire. In this waythe shock is broken by the yielding of the harp, the reboundof the wheel is prevented and retention on the wire issecured. The spring is well housed within the shank of theharp and is protected from the weather and possible acci-dent. The harps are made in rigid and flexible head. The. * AND WHEEL COMPLETE flexible head is a very simple device which allows the wheelto turn slightly, following the wire in taking curves. Thewheels can be set and removed without the use of the rigid and flexible head have the cushion shank. The company also makes standard wheels of new metal,free from lead. A recent letter to the company from aNew England railway says: We have been using the twotrolley harps and wheels which you sent us for trial and sofar have found them altogether satisfactory, our men evenmaking efforts to try to run the wheels off the wire on■curves and not succeeding. SCHEDULE INDICATOR FOR CARS An ingenious device for giving the times for arriving atpoints or stations, to be carried on the front platform or inthe cab of a car, has recently been invented by E. , superintendent of the New York & BrooklynBridge Division of the Brooklyn Heights Railroad Com-pany, and is shown in the accompanying engraving.
