BOILER. Application m December 2 ,1919.- seri 1"1'vo.s4s,iis. f

' Our invention irelates. .toboilers, and has for an ob ect tov improve the construction.

and efficiency of this: class of structures, and

to provide a portable boiler, capable of use" for generating :steam. for light engines, and especially foruheating flats, dwellings, business places, orflthe like,, either by .-;steam or hot water.

Among I I tion are to provide aboiler in which the heated gases and products of combustion arebrought into contact; with-1a greater portion of the .water carrying, parts of the honey to more quickly heat the same to provide an. improved hopper and .fire box construction below the magazine, "and to regulate the entry '[and distributionot. air to the fire to give a substantially perfect combustion and smoke consumptiong togeifect a material saving in .fuel consumption, andfmakeipossible l the eificientuse of practically any grade of bination, construction} andiarrangementof coal; the provision of a novelarrangement o ter; u e Q bs rb h ma im m amount of heat from the gases of combustion; to produoe 'a-, more simple, economical y and eflicaciousfboiler, capable ofuse either. for generating steam-orheating water; and such further objec ts,:.advantagesand.capabilities as wilLlater-more fully appear... 3

Our invention further (resides in the com I parts illustrated in the accompanying drawings, and whilefwe have shown therein a; preferred embodiment, we desire itfto be understood that thesame is susceptible of modification and change, without departing froin the spirit of our invention] f I In the drawings "Fig. 1 is a vertical transverse: section through .a', median plane f of our "improved boiler, "a slightIportiori of the upper left sakeof clearness- I 7* F g. 2 1s alfragme hand corner being shownineleva-tion for the Fig. i 1, but taken, on a median plane at; sub.

Connecting and estabhshmg' communica therefrom a suitable distance to ,.form the tion between the outer waterfleg and the in net-water leg, atithe upper portionf are the tubes 7, andat the lower portion the water llb'es 8. Thetubes '7 will or will not (be filled with water, dependingon how high the water level is maintained inithe boiler.

If the boiler-is used ,forfsteam' purposes, it

it' isobvious a suitablesteamqspace will be left above the" level ofthe water, while if 5.11 of the tubes. 1

r The space within the inner-wall t forhris a ruetmagazine 9, provided-at its upper end,

with the removable cover: 10, .for-the introduction of fuel .thereinto, In.addition to.

tubes '7 and8 there are other watertubes 1 1,

extending radially from the l inner water leg, andv closed at their outer ends,;as shown in Figs. 1, 2 and 3. Thewater in the tubes 11- is thus positioned. to be quicklyheated by v the transfer of heat; through the tubes 11,

from the heated gases and-products of com an obvious manner.

ff Attached Ito the 1061191 at? a fconven ient point is the steam gauge 1% whichmay hbe.

of any type desired to suit. the required 7 conditions. When the l x ilertis used merely as awater heater, suchflsteam gaugemay,,;of

fromjwhich the combustion gases are led;to

the stack, throughthe pipe,connectioii 13, in f course, be omit-ted. f Atthelowerend ofthe outer water leg is the intake -pipe 15, through which water-may be suppliedftq the boiler, and at the upper; end of the inner 'waterjleg is the. outletpipeLlfito conduct awaythe steam or hot water from the boiler, to the place. of consumption. LWhenjthe" boiler is used in a hot waterheating} plant, -th e ,circua lation of water will be outwardly. from the boiler through outlet Various radiators and other passages, and back through pipe 15, to the lower part of the boiler.

Below the lower end of the flue magazine 9, is the fire box 17 in which is provided the hopper 18, which may be built of fire brick or other suitable material, and the

opposite faces

19 and 20 of which, as shown in grate 23, below which is the ash pit 24, pro

vided with door 25. Through one of the walls of the hopper 18, is the passageway 26, opening into the hopper just above the grate 23, and provided with door 27. Above the passage 26, and approximatelyat the upper end of the'hopper, is the opening 28, controlled by closure 29, which may obviously, if desired, be in the form of a door, or other suitable enclosure, capable of operation, to control the entry of air to the combustionchamber.

Passing through the

walls

1 and 2 of the outer water leg, at a point near the top of the hopper, as shown in Fig. 2, isthe air inlet pipe 80, which extends to a point well within the fire boxand directly over the fire.

Pipe 30 is provided at its outer end with the closure 31, which may be hinged or movably mounted in any suitable manner to permit its being opened or closed, to regulate the entry of air from without, through pipe 30, to a point directly over the fire. Any suitable number of these air pipes 5 0 may be provided, and the amount of air passing therethrough for discharge over the fire will be regulated by operation of closures 31, to permit more or less air to pass into the fire box, as desired.

Doors

25, 27 and 29, and closure 81, may if desired, be provided with sliding grates, or of any other suitable construction to regulate the passage of air therethrough. The fire can be cleaned either through the grates or the space at the bottom of the hopper.

Referring to Figs. 1 and 3, it will be seen that in our improved form of boiler, the combustion gases will pass upwardly from the fire, through the combustion chamber, and around the water tubes, in such manner as to come in contact with the maximum amount of exposed water retaining surface, whereby to greatly increase the steaming or heating ability, to absorb the 'maximum amount of heat from the fire, and to greatly increase the economy of operation of the boiler. The fuel will feed downwardly in an obvious manner, into the hopper 18, and by suitable manipulation of

doors

25, 27 and 29 and closure 81, we are enabled to secure within the fire box perfect combustion and smoke consumption.

We consider the air intake pipe 30 of great importance, since through it air may be admitted to the fire at a point and in such quantities to give the proper mixture of oxygen with the combustion gases to produce perfect combustion. Vith this arrangement we are enabled to admit air to the fire, either from below the grate, above the grate at the bottom of the hopper, above the grate at the top of the hopper, or through the pipes 30 to a point directly over the fire, or any of the obvious combinations possible from such arrangement, as desired; thus adding greatly to the flexibility of the fire control, and enabling the operator to easily respond to any requirements of the fire to give perfect combustion.

I Having now described our invention, we

claim 1. In a boiler, a vertically arranged cy-' a lateral opening extending through the lower portion of the hopper and the shell just above the grate, adjustable meansfor admitting or excluding air to the interior of the bottom ofthe fire through said lateral opening, one or more openings through said shell at the upper level of the hopper to admit air just above the fuel bed, adjustable means for admitting or excluding air through said last mentioned openings, whereby any combination of admission or exclusion of air below the grate, above the grate at the bottom of the'hopper, or above the hopper may be effected as desired.

' 2. A boiler of the character described comprising an outer fluid containing shell, a fuel magazine consisting of an inner fluidcontaining shell enclosed within and concentric with said outer shell, means providing communication between said shells, a fire box enclosed by the outer shell and located below the'lower end of the inner shell so that the products of combustion will pass upwardly through the space between the shells, a hopper in said fire box, means providing an outlet for said products of combustion, a grate in said fire box below said hopper, and means by which air may be selectively admitted through said outer shell into said fire box at a position above the grate and at the bottom of the hopper and at a position above the grate contiguous to the top of the hopper, and directly over the fire therein.

3. A boiler of the character described comprising an outer fluid-containing shell, a fuel magazine consisting of an inner shell enclosed within and concentric with said outer shell, means providing communication within said shell, a fire box enclosed by the outer shell and located below the lower-end of the inner shell so that-the products of combustion will pass upwardly through the space between'the shells, a hopper in said fire box, meunslproviding an outlet for the products of combustion, agrate in said fire box below said hopper, said outer shell having openings positioned to introduce air into the fire box at positions 'contiguous to the bottom end the top of the hopper respective i 1y, means controlling admission of. air through said openings, and an air inlet tube In witness whereof, we hereunto subscribe our nanoes ,to this specification.
