To 'alliz'ohom iii-.may concern: t;

vkn'ot'vnij`that I, THOMAS GUN'NING, of Pittsburg', in. thef'countyfof Allegheny 'and State of Pennsylvania, have invented certain ew and usefuljlxnprovements in Feed-Water En'riliers; andi-,do hereby declare the followf fito .be `a Yful],"olear, and 'exact' description the invention,` such as'willvenahle"others'v killedin .thefart to w akeaudjusethe same.v his .invention fis afeed-Watertpurier; for' .boilersandisl-'designeditoremoye 'all impuri-f Aties '-Irom t`eed1` water -I )efore entering the` --boiler,thereby'preventi-ngjscaIes or incrustang `onktheiinterior ot the boiler-shell. i nrthefr'objec't is. to provide a puritierof his 'attire-@which -shall. possess advantagesdn oi'nt t s i'mplieity'andfinexpensiveness, `and' which vwill be practically automatic ationand not require constant at-v vv'llheseobjects I-.accomplish by empleying afcasingor cylinder into which the' feed-water f is first fed and passingthrough th'is 'cylinder acoiled 'steam-pipe. One .end of-this pipe connects-'withthe-dotne'or'npper portion of the boiler,"and its'other vend opensV 4l yinto theboiler-shell ata point above thewa-l l'line therein. i" lhuszthe steam is continu-- usi-y' passing through the lc oiledpipe in' the p'riiier and .thefeedwater in the latter is heated to about the same-degree'asjthat in the boiler, causingthe impurities to separate andfall on; a false bottom ofthe Acasi1 1g,'by `'x'vhich'they'are directed to the blow-oft pipe.

35 5. l 'lhenvention comprises the novel features of construction and also the detail combination; and arrangement of parts, substantially. las hereinafter fully set forth,1 and particularly `Inthe accompanying drawing, th'e"'gure is` falview showing myj'improved water-purifier interior of `the' casing A. -E's a steam-pipe which opens through 'the i this bottom. To the center'of the headfpla'te 'lonnected apipe B, which leads to boiler X. @Ofshoinli 'Supplied 'to casing A by a pipe A 'd at itsgvertex, throughwhich the sediment. 6o

passes tothe bottom proper. Thisfalse bot-l torn is securedat its peripheral edge d, to the 's ideof casing A near the top thereof, leading` 6 5 from thesteam-dome of the` boiler. Within this casing this pipe. 'is formed into a'coil e' and is passed out through the. side of thecasing` ate' above-thefalse vbottorn, and is then carried to the boiler-shel1, into which it opens. r}q at'jpoint'above'the.water-line therein.A Thus there is a continuouscircula'tion of steam-and a constant passage thereof `from the boiler to and through the -pur'itier 'andthence back to v'the boiler. In this Way the steampress'ure in 7 5- the boiler is not perceptibly diminished, as the v stea'rnis merelydirected therefrom and then returned thereto.v I

In practice water' vfrom vthe exhaust-heater' is'fcd throughppe bto'the purifier, and the 8e -heatfgenerated bythe steam-coil causes the 'impurities in-the water'to f all to the bottom Aand -the. PurifiedV water ascend's and' passes lthrough pipe B tothe boiler., The sediment l 'fallingonto thefalse bottom passes through 85.

the openugin'the latter tothe outlet and 'is' removedfrom the lpiuincrv byl opening the valve in the blow-o pipe. 1'

From what'has been'saidfit will'be seen that 'I -a purierconstructed-as hereinfdescribed is 9o i extremely simple audinexpensive, that there is no Waste of steam trom'- the boiler, a con- --tinuouscircxilationfbeingmaintained between the latter and the purifier.`A will also bev noted that the liabilityfof sediment collectinggg .on thev bottom ofthe p urier i's reduced to a minimum, since-all sediment willfall through the tapered'ffalse bottom' directl51 to the outlet opening.' The 'purifier can be located at any suitable point relatively to the boiler. I'olaim as my inventionf '1. In a feed-water purifier, a casingor cylf inderv provided with a lower blow-off opening and water inlet and outlet openings, a blowo pipe connected t'o said blow-ott opening, a tapered false-bottom in saidcasing having a lower central opening', and the coiled 'steampipe in said casing above said false-bottom, said water inlet and outlet openings being above said bottom, substantially as set forth` 2. The combination with a waterboiler having an upper steam space, of a feed-water purifier comprising a casing Vor cylinder having` an upper head-plateprovided with an outlet opening, the pipe connected thereto leading to the boiler, a lower bottom plate having a" central outlet opening a pipe connected thereto, a tapered false-bottom above said said boiler at points above the water line zo therein, substantially as set forth. l

In testimony whereof I have signed thisl specitication'in the presence of two subscribingwitnesses. Y
