"POCAHONTAS" 1941 These three ships of the Virginia Ferry Corporation, plving the 26 miles between Little Creek and Cape Charles, have piled up a total of 2,949,504 miles -- without a single major repair. According to the owners: "The main engines have had no major repairs on any of these vessels. No steam or bulkhead packing has been renewed. No liners have been removed from any main bearings or crank boxes. Each vessel has had just one complete change of piston rings. You have to put your hand on the engines in order to tell they are turning over." Each of the three ships is propelled by two 4-cylinder Skinner Marine Unaflow Steam Engines. Skinner Marine Unaflows are available in various lengths of stroke, and in sires having from two to eight cylinders, with ca pacities from 400 to 6000 horsepower, suitable for the propulsion of ocean going, coastwise, harbor, and inland waterways craft. -ii One of the two 2,000-hp Skinner Morine Unofl Steam Enginet in the S.S.

SAFER... MORE EFFICIENT Now, after completing exhaustive tests, Crane pre sents this better diaphragm valve--better suited for more services under today's working conditions. Stemming from basic improvements, such as the rad ically new bonnet-sealing and valve-seating arrange ment, this original Crane design introduces many outstanding service features like those shown here. WORKING PRESSURE- ISO Pounds water, oil, oir or gas 180 Deg. F. 1 maximum temperature 1. LONGER DIAPHRAGM LIFE, because diaphragm is used only to seal the bonnet--not for seating purposes. 2. POSITIVE SHUT-OFF in case of diaphragm failure. This is an exclusive Crane safety feature. 3. ACCURATE SEATING -- new flat face disc with durable, re silient seating surface assures tight closure on all fluids. 4. GREATER FLOW CAPACITY with reduced resistance and pressure drop, assured by Crane Y-pattern body design. 5. EASIER OPERATION--Crane separate disc and diaphragm construction takes less torque--fewer turns--to operate.

It is not subjeetto crushing and rapid wear. The seating member is a separate cir cular flat face disc, firmly attached to the stem and joined to the diaphragm with a special leakproof connection. This independ ent seating feature permits positive shut-off with no loss of fluid, even in case of diaphragm failure. % v, /i This new Crane line includes iron valves with screwed ends in sizes V4 to 2 in.; with flanged ends from to 4 in.
