A simple ejector may be made out of ordinary pipe fittings, which will compare very favorably with some of the ejectors on the market. It may be used in draining a flooded cellar, in which case it may be attached to the ordinary water faucet for motive agent. It can also be used for emptying cisterns or in excavations for new work where water is struck. (Of course, in this case, steam will be used as the motive agent.)
Some time ago the writer was engaged in building a reservoir, and at a depth of 15 feet a spring of water was struck. Having no means at hand to get the water out of the excavation, an ejector was made out of some old pipe fittings. Four such ejectors kept the water level down while the work was being done. One of these ejectors worked night and day for nearly three weeks until completely worn out owing to the fact that a great amount of sand and gravel was carried through.
These ejectors can be duplicated as follows: First take a 1 1/4 by 6-inch nipple; screw on each end of the same any kind of fitting so as to preserve the threads. Heat the nipple in the middle to a white heat. Then swedge down until the outside diameter is about 3/4 inch. When cold remove the fittings, and the cone is made. See A, Fig. 300.) Now take a 1/2-inch pipe, heat one end to a welding heat, and swedge down to a long point. A 3/16 rod may be inserted in the end to give the hole the right dimension, as it may be drilled out afterward. When cold, thread the pipe about 4 inches and screw on a jam nut B. On the "rim" of a 1 1/4-inch tee attach the cone above described and then a 1 1/4-inch elbow into which screw a close nipple. On the other end of the nipple screw another elbow, forming a kind of step or stop. To this elbow may be attached either a hose or a pipe to carry off the water. On the opposite end of the tee attach a reducing bushing, into which insert the nozzle shown at C. Care should be taken to get the nozzle in perfect alinement with the cone, and when in proper place, screw up the jam nut with some packing behind it, to make it air tight. In the other opening of the tee attach a pipe or a very heavy hose, preferably "ironclad," as the suction will have a tendency to close it up.
