The single curve pull over fitted with type W trolleyclamp is here illustrated. The yoke and adjustable coneare made in one malleable casting and insulated from. SINGLE CURXE UAN(;ER—TYPE W. span-wire by the small Mansfield strain insulator. Thispull over was designed to meet the demand for a curveinsulator of minimum weight for use on the smaller sizedtrolley wires. It is strong enough however to supportNo. o, B & S trolley wire. The double curve pull overis similar in design and detail to the single curve pullover but has a double yoke and double insulation. Thecurve hanger bodies are made of the best malleable cast-ing, giving strength and lightness. The insulating piecesare moulded from a special compound and the top andbottom pieces are dovetailed together and into the hanger body to prevent surface leakage. The iron castingwhich is moulded into the insulating cap is larger thanthe inside diameter of the collar, thus insuring insulator caps and washers for type W hangers areinterchangeable. The Mansfield strain insulator is a superior device. Themedium size has a breaking strain of 10,000 pounds andconsists of two steel
