l I V l IMPROVEMENT-m STEAWGENERATORS. f
` The Schedule referred to in these Letters Patent and making part of the same.
t We, WILLTAMJ WnsToN, `Vilnnmar It. WESTON, `NATrrnNIELWnsTomand `BunT BRETT, of the-city of StevensPoint, countyof Poi-tage', State of `Wis` consin, ,have invented certain Improvements iny Stea1n- Bole1s,`ot'I whichthe following is aspecication.
I The'first part of our invention relates to improvel ments inthe construction,icombination, and connections of the'tubnlarV parts yof steam-boilers, constituted y of. tubes "of smallA diameter, for holding water and generating steam, the-improvements.consisting of improved forms, combinations, and connections of the sections of the'boi'ler, formed` principally of horizontal parts, connected by vertical parts, the sections, so combined `and` connected as to form a tire-box for the -conibnstiouofthe fuel, and a simpleform of "boiler, having` only one'combustionfchamber, the forms, combinations, and connections of the sections` l i Hue, for the purpose of retaining the heat.
.The objects ot'` the' rstandsecoud parts of onrinvention are to secure safety from explosion, economy of fuel and space, and forms ofboiler adapted to portai p blejpurposes.`
IThe third" part-fof our Vinvention relates to an in-` closure of the tubular parts of 'the boiler.
.This 4inclosure consists of the. combination of the Vtubular `beams with `tile front and rear plates, by the iauges at fthe. base of vthe plates' forming a `substantial frame, together with the useof plates, attached by vbolts ahdltlanges, on the sides and tops ofthe front and rear plates,'in thefmanner hereinafter described, all `.constructed of iron, or other metal, forming a strong and symmetrical inclosnre, with comparativelightness, forthe purposes of supporting the tubular parts and keeping them firmly in place, preventing the lossof heat ,by radiation, as well as Iconfilling the heated air` of thel tire-box, aiiording easy access tothe tubular .partsof lthe boiler, for cleaning` and otherpurposesrandavoiding the use of cumbrous inclosures.
Eescript'ionof the Acconqianying Drawing. y Figure No. 1 `represents a front view ci'` the boiler.
" Figure No. 2 represeutsa rear 'view of the boiler.
Figure No. 3 represents the top of the boiler. Figure No. 4 representsthe tubular parts of the l `boiler -in front.`
` Figure No. represents the tubular parts of `the boilcrin rear. Y
` Figure No. 6 represents thev tubular parts of the boiler on the top.
Figure No. 7 represents-the left side of the boiler.
1 Figure No; 8 Vrepresents the tubular parts of the "boiler `on the left side.
The preceding drawing relates to a form of,v they boiler combining a series of combustion-chambers .with the tire-box. v
Figure No. 9 represents an intermediate section, in a simple form of the boiler, having only one combustionchamber, as indicated in gs. Nos; 11, 12, and 13. r fligurelo. 10 `represents an intermediate section in a modified form of the boiler, having one or more series of horizontal parts, F F', added, for the purposeof forming combustion-chambers in combination with the fire-box, as indicated iniig. No. 8.
. Figure No. 11 represents a section of the boiler in front, in a'. simple form, having only one combustion-r chamber.
-Fignre No.12 represents a section of the same boiler in rear.
Figure No. 13 represents the tubular parts ot' the same on thel left side.
A is the front plate of the inclosure.
B isthe rear plate.
C C are the plateson the sides and top of the inclosure.
D isthe door of the furnace.
` EE are the tubular beams at the base of the in-` closure for the support `of' the front and rear plates, tubular iu form, for the purpose of combining strength and ligh'tnmss,` and with the front and rear plates cony stitutiug the frame of the inclosure.
F F are thelorizoutal parts, and
Gr G the vertical parts of the tubes, for holding' waterand generating steam, forming the principal parts of the tire-box for the combustion of the fuel, and
4constituting the boiler in a 'simple form, having only one combustionfchamber, as shown infigs. Nos. 11, 12, and 13.
.Additional tubes, F F', may be inserted `in someof the intermediate sections, as well as the front and rear sections 'of tubes, to vary the form oi' the boiler, one of the variations being shown iniigs. 8 and 1(4), forming, in combination with the fire-box above dcscribed, one o1' more series of horizontal tubes, F F', and" forming combustion-chambers or a serpentine ilue,ias shown in iig. 8.
About two-thirds of the lower row of the horizontal parts F, next to the front plate, are alittle smaller .than the remainder of the part-s of the same rownext of permitting the heated air of the furnace to iiow AND around the Vertical parts and heat them on all sides, without permitting so much of the radiating heat of the tire-box to pass through among the vertical tubes as to injure the side plates of the inclosure.
The tubes F F and F F', in the front and rear sections of tubes, are a little separated from each other in their respective sections, for the purpose of allowing a free circulation of heated air around the tubes, without permitting so much radiating heat from the {ire-box to reach the front and rear plates as to injure them..
H H are short vertical branches of the lower horizontal tubes F F, with flanges, for the purpose .of couneeting tbe tubular sections by the lower transverse tube O.
N N are vertical branches of the transverse tube O, with a continuous flange, for the purpose of connecting the tubular sections and admitting supply water.
K is the upper transverse tube, for receiving and holding steam, with vertical branches, I I, and a continuous ange, f, for the purposes otl connecting the tubular sections at the top, and binding them lirmly together, and conduct-ing the steam into the upper transverse tube.
L is the cap of the upper transverse tube l.
M is a flange on the top of the tube K, for attaching a steam dome and-other usual attachments for receiving, regulating, and transmitting steam from the boiler.
It is the flange on the rear plate, for connecting the chimney of the furnace.
a a are the flanges at the base of the front plate A.
b b are the flanges at the base of .the rear plate B, for the purpose of-attaehing the front and rear plates to the tubular beams at thc base ot' the inclosure.
c c are the bolts for fastening the parts of the boiler above described together.
g r/ are the flanges at the ends of the horizontal parts F F and F F and the tops of the vertical parts G'Gr of the tubes.
h h are the caps for closing the ends and tops of tile horizontal and vertical parts of the tubes, the caps being fastened with bolts and countersunk, makthe heads of the bolts even with the faces of the caps, (omitted in figs. Nos. 6 and 8, in parts of each figure, to show the forms ofthe tubes and flanges.)
l l are flanges on the front and rear plates, for the .purpose of attaching the side and top plates.
plates, for the support ot' thetubular parts of the boiler.
p is a flange on the inner side of the front plate, opposite the row of tubes F F ou the upper side of the fire-box, in fig. S, to conduct the heated air through the chambers of the furnace or flue.
s and t are ilanges, similar to those last named, on the inner side of the rear plates, opposite the lower F', next below the chimney, in tig. 8, extending along the whole length ot the tubes, for the purpose of conducting the smoke and heated air through the chambers ot' the furnace.
What we claim as our invention, and desire to secure by Letters Patent, is as follows:
1. In combination, the horizontal tubes F and vertical tubes G, surrounding the' fire-box, and .disposed in front, rear, and intervening sections, substantially as described.
2. In combination with the foregoing, one or more series vofL horizontal tubes F', forming combustionchambers or a serpentine flue, substantially as described.
3. In combination with the foregoing, the metallic iuclosnre, constructed substantially as and for the purpose set forth.
