IMPROVEMENT IN WATER EJECTORS.

To ALL wuoM 1T MAY conozcan;

Be it known that I, HENRY S. LANSDELL, oi the' cit-y, county, and State of New York, have invented a certain new and useful Improvement on Steam Siphons or Ejectors, oi` which the following is a full, clear, and exact description, reference being had to the accompanying drawing, which forms part ot' this specification, and which represents a sectional view of the receiving-chamber, water-inlet and discharge passages, and steam jet pipe and nozzle. Y

This invention relates to that description of.appnratus known as steam siphons or ejectors for raising water or other liquids by the injection of a jet of steam or other aeriform huid, at a suitable pressure, into a liquidreceiving chamber which forms a connection lbetween the inlet and delivery pipes or passages. It will sufce here, however, in illustration of my improvement, to allude to water as the liquid to he raised, and steam as the injecting agent, though my invention is not restricted to these.

The nature of my invention consists in a novel construction of the receiving-chamber of the ejector with two or more water inlets, so arranged that the water entering the said chamber by the said inlets in separate columns may, without the columns obstructing each other, or being obstructedby lthe jet pipe, be delivered in one solid column; and my invention further consists in furnishing thejet pipe and its lowest pnrt with an escapevalve which is opened inwardly by a spring or other means when the pressure in the pipe is no greater than that outside, for the purpose of allowing the escape from the said pipe of any water resulting from the steam that may condense therein, and thereby preventing the formation of lice in the said pipe in cold weather.

Referring to the accompanying drawing, F is the receiving-chamber, which may bomainly oi' globular form, or the upper part of it made circular iu its horizontal section, and constructed for the attachment of the delivery pipe, d, by means of a screw or otherwise, and the lower part of which is formed with two opposite inlet nozzles, m zt, which have such an inclination Vor curvature that the water entering through them into the chamber in two columns, will pass freely upward without the two columns obstructing each other, and unite in one solidrising column. Inlet pipes are represented attached to the said inlet nozzles, but these may be dispenscd with when the nozzles are immersed in the water to be raised. Gr is the jet pipe through which the steam employed to raise the water and force it to the place desired, is admitted to the ejector. This pipe, by its nozzle, s, enters the chamber F at the bottom between the inlet nozzles, and projects upward into the chamber a short distance, .but not far enough to obstruct the columns of water entering by the inlet nozzles. The lower part of this pipe lresembles an inverted siphon in form, and at the' bottom ofthe bend there is an aperture tted with an escape-valvmp, opening inward, and to this valve a spring, g, istapplied in such manner as to open it when the pressure Within `the pipe G i's no greater than that outside,- and thereby allow the escape of any water resulting from the condensation of steam that may havo collected in the said pipe, if thev lower part oi' said pipe is not submerged in the water to be raised, or prevent any accumulation of water therein above the level of the water outside of the said pipe and chamber F, when the lower part of the said pipe and the chamber are submerged. If more than two inlets are used they are arranged at equa-l distances apart, or thereabouts, around the chamber F, but otherwise in the same manner as when only two are used. Among the various purposes to which this ejector, constructed as represented, and provided with suitable attachments, is applicable, may be mentioned the raising of water from mines, relieving the holds of vessels from bilge water, also the discharge of the ashes from steam ships or boats. For the latter purpose water is' admitted through a sea-cocl linto a reservoir or receptacle arranged below the ash-pit, and into which the ashes are collected, and the ejector is so applied as to discharge the water from this reservoir or receptacle. The water being so discharged carries the ashes with it. Tllhe steam jet, instead of being admitted through an entirely open nozzle, as represented, may be made annular by inserting a centrepiece or core in the mouth of the jet pipe. l

What ,I claim herein as new and useful, and desire to secure by Letters Patent, is

j 1. The arrangement of the two or more water-inlet pipes or nozzles m m, in relation with the nozzle 8 of thejet pipe and liquid-receiving chamber, substantially as and for the purpose specified.

2. The combination, with a steam siphon or ejector, of an escape-valve p, applied tothe jet pipe G, for operation, substantially in the manner and for the purpose specified. i
