. Science of railways . American Gravity Tank Hose Coupling. This coupling will last indefinitely as there are no threadsto be stripped, all binding pressure being against the yield-ing gasket, which is round and can be turned over, present-ing a new face. These gaskets may be made of lead, castin wooden moulds, at any roundhouse. Castings are of malleable iron, properly proportioned andaccurately machined. All sizes are interchangeable. 631 632 LOCOMOTIVE APPLIAXCES. From above illustration it will be seen that the gasketwill be compressed by the sliding together of parts A and strainer

From above illustration it will be seen that the gasketwill be compressed by the sliding together of parts A and strainer is placed in the opening in B. The operationof this coupling requires no tools except a small wrench toadjust the set screw in the top. Part A is furnished if de-sired with wings cast on sides of hub to bolt to a Tank Hose Connection. OKADEE TENDER HOSE COUPLER The Okadee. tender hose coupler is simple in construc-tion, durable and reliable. It can be disconnected, cleanedand connected in about one minute, without the use of ahammer or large wrench. A few turns of a monkey wrenchwill release the nut and allow the coupling to be opened. Thenut does not have to be taken off of the bolt, and a cotterpin prevents its being lost. LOCOMOTIVE APPLIANCES. 633
