Letters Patent No. 104,573, dated Jima 21, 1870.' i

`Arrunga'rusron UrrLrzmG Tm: nxHUs'r STEAM or STEAM-ENGINES.

The` Schedule referred to in these Lettera Patent and making part of the same To all whom 'it may concern Be it known that I, HENRY'GEBNER, of thecity,

Y county, and State of New York, have inveuteda new and improved `Apparatus for Utilizing the Exhaust Steam of Steam-Engines; a'nd I do hereby declare the i followingtobe afull, clear, and' exact vdescription of the same, reference being. had to the accompanying ,drawing formingpart of this specification, in which steam-generator in such a manner that no portion otthe latent heat of the exhaust steam is lost, the said exhaust steam being mixed with the live steam in the receiver While `the water is pumped back into the generator, and by these means a Vlarge percentage of heat generally wasted by allowing the exhaust steam to es- `cape in the atmosphere, or by condensing it in a condenser, is saved."

In the drawingp f The letter A designates a receiver, from the side of which extends a pipe,.a, connected to a jet, b, which receives the water saturated with'steam iiom alsteamgenerator, B, through a pipe, c.

p The jet is inclosed in an air-tightjacket, d, which 4 connects, by means of a pipe, e, with the exhaust-port of asteamfengine.`

vFrom the top part of the receiver extends a pipe, j, through which the engine is supplied'with steam, and another pipe, g, which extends'from the lower portion of the receiver, Vis connected to a pump, 7L, which communicates, through a pipe,", with ,the steam-gener ator. p

, After steam of a suiiicient pressure has been raised in the generator, the stop-cock of pipe e is opened; and the water, saturatedwith steam, rushes through the jet into the receiver, `when the steam separates from thewatcr, the steam being `taken to the engine.

The exhaust steam of the engine passes through the pipc'e into the jacket d, and is carried, by the action of the Vsteam jet, into the receiver A, where it mingles with thelive steam and water, the water accumulating in the bottom part of the receiver being pumped back into the steam-generator. i

During this process the latent heat, being disengaged from that portion of the exhaust steam which condenses, is not wasted, but it serves to increase the heat, and, consequently, the pressure of 4 the noncon densed portion of the exhaust steam, enabling thesame to 'mingle with the livesteam, and to be conducted back to the engine.

No heat is' wasted, therefore, in my apparatus, except what is lost by radiation or leakage, and the same water is used over and over again, so that no supply of fresh water is required except what is needed to make up l'or the loss by leakage, though it cannot be denied that a certain loss of power will result frpm the v Y operation of the-pump required to return the water to the generator; also, from the diminished tension of the steam employed for working the engine, and from the back pressure which will or may be caused by the ac-v tion of my apparatus on the exhaust steam, and the exact amount of gain resultingfrom my apparatus, or, in other words, thecorrectness of the'thcory set forth in the above-description, canonly be determined by future experiments.

What I claim as new, aud desire'to secure by Letters Patent, is

The arrangement of a rceeiver,iinto which the exhaust steam from a steam-engiuejis driven by the action of a jet of live steam'and water taken from a steam-generator, vand from which receiver steam is taken to drive the engine, while the water accumulating in the bottom part thereof is pumped back into the stcamgenerator, `al1 substantially in the manner and for the purpose herein shown and described. v

rlhis specification signed by me this 7th day 'of April, 1S70.`
