All the best, Mark. [/quote] Mechanical Lubricators were an option. They simply replaced the Fireman going around with the oil can at each stop. [/quote] No, they didn't. Mechanical lubricators largely replaced hydrostatic lubricators. Lubricators of either type were not an option. The fireman can't go round with an oil can while running and feed oil into the valve chests and cylinders. That's the main purpose of the lubricator. Grease lubrication of rods and motion is what replaced the fireman going around with the oil can at each stop. All the best, Mark. [/quote] It depends on the time you are referring to but sometime between the Tom Thumb, Good Freind of Charleston, John Bull era and old 999 lubricators came about. McCoy was supposed to have it's reputation for it's superior design.
