"The old Hemingray Number 40, widely used from its introduction in 1910, was replaced in 1921 by the Hemingray No. 42."

"The No. 42 is a double petticoat type, with a long, smooth leakage path on the inner petticoat. It sits close to the cross-arm, thus giving the pin protection against rain slash. Its threads are accurately formed for a tight grip on the pin. The wire groove is a modern square type shown in Spec. 1-A-33 of the Association of American Railroads, and is accepted as standard for most telephone construction."
