. The Street railway journal . ....BUT. TROLLEY HARP of KALAMAZOO. THE KALAMAZOOTROLLEY HARP is like the Kalamazoo1 TrolleyWheel—it is nearer perfection thanany other device of the kind onthe market. The springs on the Harp are fullyprotected and cannot possibly bebroken. As the friction of thiswheel is borne entirely by theheavy washers or lugs, there isno wear on the springs, and theynever have to be replaced duringthe life of the Harp. The Kalamazoo Trolley Wheelscombine extraordinary durabilitywith the minimum of wear onthe overhead wire. It is hardto find a road that is not usingthem.
