[Vol. XX. No. 23. High-Voltage Transmission Insulators The accompanying illustration shows a high-voltage transmissionglass insulator manufactured by the Brookfield Glass Company,of New York. This company has been very successful in the manu-facture of glass insulators for high-voltage work, and the one. HIGH^VOLTAGE GLASS INSULATOR illustrated was constructed for a transmission line carrying 45,000volts. The diameter of the insulator is 7^2 ins.; its height is 5^ins, and the distance measured around the insulator from thecable to the pin is about 12 ins. The groove for the cable is Ij4ins. in diameter, and the weight of the insulator is 45^ lbs. New Trolley Wheel and Harp A new trolley wheel and harp, embodying novel improvements,are herewith illustrated. Fig. 1 shows the device from above; is a side view ; Fig. 3 a longitudinal section, and Fig. 4 a sectiontaken in the transverse and in direction of the axle. These improvements relate to the harp, wheel, axle and itsbearings. The wheel, A, is a composite wheel, consisting of thegrooved central conductor, B, made of an alloy of best mixturefor being revolved by tractive force from a line wire without liabilityof rapid reduction of the metal. This grooved conductor is liableto become worn, and is therefore arranged to be removed
