d. To all whom it may concern:

Be it known that 1, JAMES A. DILLON, a

' resident of Chicago, in the 'county of Cook and State of Illinois, have invented certain new and useful Im rovements in SteamCondensers, of which t e following is a full, clear,

' and exact description.

The invention relates to steam-condensers, and designs to provide improvements in the type of condenser set forth in Letters Patent of the United States No. 582,813, granted to me May 18, 1897.

Oneobject of the invention is to provide an improved construction in which the heat units of the exhaust-steam are better utilized inheating water.

Another object of the invention is to pro. vide improved means for spreading water for I contact with the steam.

Another object of the invention is to provide improved means for separating .the oil sus ended in the steam from the steam.

'astly, the invention designs to provide an improved construction of combined condenser, separator, and heater.

I The invention consistsin the several-novel features hereinafter set forth, and more par-- ticularly defined by claims at theconc'lusion hereof.

In the drawings, Fig-at '1 is a lcentral vertical section of a steam-condenser embodying the invention. v Fig. 2 is a'similar view showing a modified form of the invention. Fig. 3 is a horizontal section taken on line 3 3 of -Z 10 denotes a cylindrical casing of the condenser, ,within whichis provided a steam chamber 11.' The casing comprises a top 12,

removably secured to theb'ody of the casing for convenience in cleaning the parts therein.

The lower portion ofthe casing is tapered, as

. at 10; A cylindrical Wall 22, having a ooseparating-pocket near the lower end of the steam chamber and formed between the lower CO'IlOldfll portion 23 of the inner wall of the steam-chamber and a vertical wall 13.

At the bottom of Wall 13 a channel is formed inwhich oil extracted from the steam is collected, said channel being formed by forming anupwardly-extending flange 1.3 at the inneredge of the bottom of wall 13. A space 14 is formed between said channel and Wall 23 for the passageof steam. An oilpipe 20 for conducting the oil extracted from the steam to any desired point is connected to the'bottom 17 of the casing? The oil col lected in the channel in the separating-pocket passes through a-pipe'2Q to pipe 20. Steam directed into the separator pocket or chamher through elbow 16 passes around the lower portion of wall 23, and therebycomes in contact with the walls of the pocket, which causes the oil to adhere to the walls of the pocket, and thus effects separation of a large portion of the oil from the steam. The oil which collects around the lower portion of wall 23 gravitates into the lower portion of chamber 11 and thence to pipe 20. The oil collected in the channel at the bottom of the separator-pocket passes by pipe 20 to pipe 20. The purpose of providing the separator pocket or chamber around the lower portion of the wall of thecondensing-chamber is to heat said wall so the water passing thereover .will be heated.

Wall 22 is arranged inside of chamber 11,.

around which the steam circulates and which extends to a point near the top of the casing, so thesteam in chamber 11 must pass to the top ofthe chamber before it is brought in contact with the water for condensation. The lower portion of wall 23'has connected thereto at its reduced lower end an outlet pipe 24, which conducts the purified heated water to any desired point. A pipe 25 conducts cold water'onto a spreader-plate 26, which is preferably of the form shown and is rovided with an upwardly-extending annuiiir wall 27, having perforations'28 therein.

The'water delivered onto the spreader passes through perforations 28 to the outer edge of the spreader, where it is directed against wall 22. The water passes from the spreader in a thin sheet, and the steam will be condensed and absorbed thereby. The water passing from the spreader'is heated by the exhauststeam and passes into contact with the heated walls 22 and 23,-so the temperature is materially raised because the wall is heated on I easing.

the buter side bysteaIn passing upwardly in chamber 11.. A hood is arran ed above ;the spreader-to prevent the steam or'n coming into direct contact with the water on the spreader and the formation of scale on the innerportion of the-spreader. The capacity of perforations 28 is substantially e ual to the'capacity of pipe 251111d61' norma pres= sure. Shoul pressurejin' pi e 25- become greater, so a larger quantity 0 water will besepplied, the water will flow from the upper "edge of the overflow flange or ring 27 and be discharged aroundthe spreader. A stack 29 for the admissionjof fair extends upwardly from the separator through the top 12 of" the The operation steam'eontaining oil in suspension is conduct- 4o "f I in chamber 11. I

in chamber 11, it passes over the upper edge 1 ed to the separator 1pocket" by pipe 15. A large portion of the oi is, there extracted, and

the steam passes from said chamber'around the lower edge of the oil-channel intoi-stea'm. passage or chamber 11, wherein the remains.

der of theoil is extracted, which passes to the bottom of the casing. In the separating chamber or poeket'etfeetive separation ofthe oil from the steam occurs therein and alsoin the lower portion of chamber 1 1 becausethe" steam does not rise quickly in said chamber before. coming in contact with the walls of the separator-pocket. Thesteam heats the walls of the pocket-andparticularly the lower portion oflwall 23 of the condensing,

chamber, over which the purified water passes. ter the .oil has been extracted passes over the upper edge of-wall 22 and into the chamber therein. The steam passing upwardly in chamber-11 heats wall 22, so the water in the inn'e'rch'amber will be heated by the steam When the steam has risen of wall 22 and is condensed by the water flow-- I is brought intov contact withthe inside of. walls 22 and 23,;so that it will be heated before it passes to outlet 24.

walls ofsai'd chamber, and as a result the tem- (mature of the water is materially raised 'beore it leaves the condenser, and thus the heat units of' the exhauststeam are utilized to heat the purified water after it has served to condense the steam; Another advantage of the improved construction is that the. 'flow of water is not limited and if excess is provided by pipe 25 vthe Water will overflow wall 27.
