IMPROVEMENT IN FEED-WATER HE-ATERS.

' `1"he Schedule` referredto in these Letters Patent and making part of the 'same4 To all .whom it maja] co'acewtri Be itkknowu-"thatjl, HAitItIsoNANDnRsoN, iu the city of Peor1a, 1u the county of Peoria, in-the State of llhnois, have invented a new and useful Feed-water Heaterand Lime-Separator 'for 'Steam- Generators; and dofhereby declare thatthe follow-y 'ing is a full, clear, andex'aet.description thereofref- `erence being had tothe annexed drawing making a* part of this@specification, inwhich like letters of reference refer te like parts, `and in whichi Figure l'represeuts a' perspective view, with the front plate removed. c

Figure 2, a sectional elevation. Figure 3, perspectivevviewiof on'e series of settling?.

Figure 4, perspective view of one series of 'heatingy troughs.

.This improvemeut relates to the retention ot' ythe feed-water in a series of` parallel` troughs, arranged one above the "other, `separated by intermediate shallower troughs or` heaters, to receive the falling water, retardit as much asp'ossib'le, andoffer a larger area forheating the same, and extractingthe'lime, Sac.

A represents the shellof the heater, the sides bcingparallel, for convenience of the troughs, and having ledges at m at to retain the .box B.

" B isla removable box, with perforated bottom, oc-v cupying.; the whole of the lower 'area of the shell over the reservoirlL, resting, as beforesaid, on thelcdgcs mum.' l

` Ithas,.ncar its top, a perforated tray, B B, which, in the drawing, is hinged tothe box. i

C lis' the induction steam-pipe, admitting steant justabove theperforated tray B B, on which hay,A straw, or other lime-separating material is placed..

D, theeduction ,waterfpipe E, the induction water-pipe with a valve, la, moved p by a lever' connectedrwith `the, float` ll, `within the theater. `Saidpipe'terminates within the heater, at

the top, in a horizontal perforated pipe, p jf. l

Il, a float attached by'a staple or eye ,and lever to, the arm got an' axle, Yto which latter, on the exterior o'f heater-shell, is fastened the lever f, which is coni nectedby the rod t `with the lever of the valve 17u' of the induction water-pipe E.

G, escape-pipe for supelgiuous steam. p H H H Hare a seriesof troughs, several being united in 'one set, (s ee iig. 3,) for facilitating -their removal, &c., each set reaching i'om side to,side of the shellA A, and placed.one^abovetl1`e other,

" alternating with the heaters K K K. They may be made about three inches deepjby iive inches wide,

each trough liavingl'a separatingspace or crevicegof l.about one-fourth' of an'` inch or more, (represented Yat ma.) '3 i ;The"eudistijips are, cast with a shoulder, 'it a, or extension upward and downward ot" the edges of the saidend strips. l A

` K K are sctsof shallow troughs, called heaters,

heater is under the opening between the troughs' above. f 1. A

The 'operation of this heater is as follows The steam is'inducted through the pipe C Linder the lowest' troughs; the water, through the'pipc E and the openings in the perforated pipe 1) 1l, into the upper range of troughs H, die., thence, running from these through thc crevices a, (t, onto steam-heated heaters K, 82e., which olier a large heating-suie,"

face for the water. This'process yis repeated until the water reaches the box B, leaving its sediment,

linie, tc., in the troughs and heaters, that remain'- ing being deposited on they hay, straw, or other material, placed for this purpose on the perforated tray' B B, (see iig. 2,) the water finally reaching the reservoir. L at the bottom of the shell A A.v

. By this arrangel'nent, the advantage of a greater arca is aiorded by the widev and shallow heating'- troughs K. K, 85s, which delays the too rapidfall ofthe water to the bottom of the heater before depositing its impurities; also, ofthe raising and retaining the water at that point (2120) below which it imperfectly deposits lime, &c.; also, the advantage of the oat L in governing the too rapid receipt-,of water, and consequent obstruction of the action ofthe lime-separating devccs.-

What I claim as my invention isi- 1. The combination of thetroughs H H, 86o., with the shallow heating-troughs K K, 85e., as arranged,

and substantially as and for the purposes described.

2.' In combination withthe troughs H H, 85o., and 'the heaters K K, 8m., the float I" acting onthe cut-ctt' valve lt in the induction water-pipe E, subttantially as described. Y

,3. 'lhe combination of the box B, with its tray B, with the troughs H H, 85e, and heatingtroughs K K, &c.', the shell A A A A, with ledges m mi, steam "induction-pipe C, water induction-pipe E, and its valve lf, ioat F, lever g, axle 71., lever j,

rod t, and lever o, and water ednction-pipe D; allesub` stantially as described. c i

-In testimony that I claim the foregoing heater and separator, I have-hereunto set my hand this 27th day of July, A. D. 1870. ff
