Be it known li, MARTIN L. DUNNAM, av citizen of the nited Sintes, residing at Meridian, in the eounty of Lauderdale end Stilte of Mississippi, lieve invented new and useful improvements in Combined Con densers and l'ieedlleter Heaters, of which 'the following is n speoioetion.

Chis invention relates to improvements Yfeed Wai/er, and more combined condenser end -ifs invention to purify ilron'i solid sind el'ien'nen-l 1mi'- pnrities and Witter .in o

lilihile the preferred :toi-ins of: this invenu 'tion nre illustrated upon the accompanying; sheet olib yet it is to be understood that ini eiuinges rosy be nmde partiv A; from the scope thereof.

Fgnrel is e. View in vertical longitudinal section7 oit the combined condenser end feed water heater es contemplated in this invention. Fig'. f2 is :in enlarged View in trans `verse vertical section of the condenser' und :feed Water heater es contemplated in this invention.

` The condenser end feed Wolter heater eoinprises e cylindrical easing l closed et en'eli end, supported above n horizontal heating ehninber extending the entire length theren under and having o vertical flue or chimney 3 :it one end to supply heet to eporize the 4water in the condenser. Aillusie heet from the boilers may be employed to supply lient to the elmniber or e. grate 4l may be provided at the end opposite the ilnev 2. lt is preferable to provide en inner wall labout the upper portion of the easing; l leaving a small space therebetween. The pipe 6 leiding.:1r from e source or water supply discharges into the space et the bottom on one side and upon the other side on external feed pipe 7 leads from the bottom or" this space into the interior of the easing l below the horizontal center line. The lower'end of the feed pipe 7 is provided with a flootopereted valve 8 arranged to close the discharge end of the feed pipe. By this eonstruction the water 'from thesource of supply is raised in temperature before being,` led into the Vaporizing portion of the condenser. A plurality of horizontal air pipes 9 are wronged in the opper portion of the easing l in. rows following the contour oi the oor ingl es near :is possible. These pipes 9 nre supported in 'the end walls of the easing end ere open therethrough, so that eooi sir will be. drown through by the draft up the flue Below eeeh row or' sir pipes 9 are er renged correspondingly euri/ed drip pieter 'LILO supported from the end vilells-o the ing 1 to celeb the ldrip of eondensetion whieh gethers upon the air pipes @rip platee l0 have their lower side edges so ooi'istrueied es to leed 'bhe drip int-o horiaoi il arranged diemetri-celly opposite il.. These troughs 1l ere preiferehly curved on the radius of a circle having their enter sides tightly secured against the inner Wells of the easing: l sind their inner sides entend ing slightly beyond e seinieirele, so that 'the drip muy be Caught and retained by there. The bloat valve 8 is adjusted to retain the Water level in the easing below 'the bottoni of ihe drip trough il. lhrough the front end or' the easing l pipes 12 leed from the bottoni of the drip trough and eoniieeted to a, pipe 13 leading to pump, which. loroes the condensed Water thrfmgh pipe to feed the boiler or batteries of boilers,

ineens of this invention the Weter is preheated by passing over the upper Wells of the con( enser proper7 'vapor-Zed in the bottoni of the condenser prope Condensed in' the upper port of the pendel er proper and oon'ipletely purified ond held in troughs :is heated. feed water until disohergged through the boilers.

What l.' claim is:

1. A. eonliiiined condenser :unl l'oed wot-er heater, Comprising :t easing -closed et each end, n. heating Chamber thereunder having' e line passing one end of the easing, s. plurality of pipes in the easing lending from the air at one end to the flue at the other end, drip plates below the pipe, troughs at each side to Catch the drip. ineens to admit the vaterto be veporized, and ineens to'leod the condensation in the troughs to the boilers. 2. A combined condenser and feed Water heater. comprising a casino, air cooled pipes passing therethrough, double Walls about the top of the easing forming s space therebe tween, ineens to supply Water to said spaee,
