Cannot steam set rs) Saves steam by assuring snug fit ew BODENLOS ADJUSTABLE PLUG PISTON Offers These Five Supenon = Adjusting is accomplished by loosening the follower, removing a small plug and inserting a tool in the pinion. This engages a rack, as shown in the cutaway. The pinion is turned until the “‘feeler” used indicates proper clearance. The follower bolts are then screwed down tight, the tool is replaced by the plug and the piston is solid once more. HE plug piston is well known to engineers as the simplest, most reliable type of piston. It is safe because it cannot steam set ... cannot harm cylinder walls. But the ordinary plug piston becomes worn after a short time in use and develops steam leaks. This means lost power... and waste. The new Bodenlos ADJUSTABLE Plug Piston can be adjusted at any time, without removal from the cylinder, to a small fraction of 1/1000 of an inch. It can readily be made smaller or larger, as desired, and can be adjusted in a few minutes at any point in piston travel. The new Bodenlos ADJUSTABLE Plug Piston is a true circle at all diameters and adjustments. It is made of finest cast iron and will wear indefinitely. It will soon de- velop a mirror-like polish and it can always be kept tight against the cylinder walls, with the correct tolerance. This revolutionary new plug piston is especially adapted for super heat and high steam pressure. Write us for further information. The AMERICAN SHIP BUILDING CO.
