. The street railway review . to it finally. Electrictraction is the only savior of non-dividend paying Unes.The Compagnie Generale Francaise de Tramways, whose annual meeting took place recently in Paris, statesthat it has been compelled to substitute mechanical (elec-trical) traction for horse haulage at Havre, Marseilles, Nancy, and Genoa. 490 ^^v{ajthl^J^^/k^ A REVOLVING TRACK BROOM. A revolving track broom, designed by G. J. Smith, master mechanic of the South Covington & CincinnatiStreet Railway, has had a 30-day trial and has proved apractical success. As shown in a plan view in Figure i, the frame is made of gas pipe, with bearings for thebroom axles on the end. Motion is transmitted by asprocket chain to the main axle which is connected throughuniversal couplings to the broom axles at each end.The chain is driven by a sprocket wheel on the axle, and is thrown in and out of gear by an idler sprocketwheel just back of the axles. The brooms can be lifted514 inches above the rail. Everything is operated from. the front platform, as is shown in Figure 2. The broomsare 15 inches in diameter and i foot long. They are ofsteel wire with hubs of hickory 4 inches in diameter and14 inches long with an iron band at the ends. Thebrooms revolve about i yi times to one revolution of thecar wheels. The driving sprocket wheel on the caraxle is split, and cast in such shape that it takes the placeof the axle collar which holds the motor in place. Theuse of the idler is necessary, not only to give the rightdirection of rotation to the brooms, but to throw themout of gear when not in use. A few cars equipped in thisway and run with the brooms down for a trip or two oneach route every day will help out the coal pile consider-ably. THE SOUTH STAFFORDSHIRE ELECTRICTRAMWAY.
