J No.a TaperBolf- Section of Screw Reverse Gear is the piston rod. This is of the extension type, and is of hol-low, heat-treated steel. Much ingenuity was shown in workingout the method of producing this unusual form of rod. Oneof the illustrations shows the rough forging which is drilledfor its entire length of over 8J4 ft The ends of the rod and the piston fit are then pressed downto the smaller diameter in a hydraulic forging press, as is shownin the second illustration. A photograph of a section of thefinished rod is impressive evidence of its lightness and strength. RAILWAY AGE GAZETTE, MECHANICAL EDITION I Vol. 88, No. 2
