| "In a hilly country where the
line is often not at right angles to the pin, it is frequently difficult to make a
good tie in the side groove of a standard insulator."
"To meet this condition, the Hemingray No. 43 is provided with a top groove added to accommodate a top tie where necessary. It is a double petticoat type exactly like the No. 42 Hemingray insulator, except for the top groove. Having also a side groove, it can be used for either top or side ties. Shown in Spec. 1-A-33, Association of American Railroads." |
