applicati@ mea nay 9, 192i. serial No. 468,028.
My invention relates toA heaters, particu larly vof the 'downor cross draft type and comprises means for controlling the l a and also for varying the width ofthe coms bustion zone so as to permit the use of different kinds of fuel in the-heater. In. my improved heater convenient accessis vgiven 'to the combustion zone both for slicing'and 'cleaning out purposes. My invention' also iu comprises the construction and arrangement of arts WhichI shall hereinafter describe andpcla'nn.
Fig. 1 ris an'elevatiompartly in section,`
of a heater embodying my invention; F'igs. i 2 and 3 are, respectively, sections on 'lines II-II and III-ful of Fig. 1; 'and Fig. 4 is an elevation, partly broken away, of the front of the heater. a l VReferring-to the drawings, the heater is ao comprised of a plurality of water sections 2 connected4 at top and vbottom by the nipples '3, and between and through the water sections are arranged the. ues 4, which lead out of the gas chamber 5. The combustion chamber 5 is arranged between the legs 6 of the water sections, which diverge upwardly from the. lower :onnectin'gl nipples 3.' The legs 6. are provided wit passageways 7 through which the air and burning gases ass from the furnace chamber 8 to the cemustion chamber 5. The legs 6 have projections 9 which limit and determine the size of the vpassages 7. 'The furnace chambers 8, of which I have shown one on each side of the heater, are arranged between 'the water le s and amovablel sectional grate 1t). Aove each grate 10 and alined. therewithis a corresponding water lfront 23 connected with the water section 2. Theupper connection is'indicat'ed at 24" (see F1g. 4'), and the lower 'connection is made by pi es 24, and connection 24"; Thus the water ronts 'form a part of the water heatingspace of the heater, as is usual. Enel issupplied to the furnacer chambers from l.the fu'el reservoirs 11 by gravity. Each movable grate 10 .is
tachedto the lower end'of the grate 10. The
fuel in the furnace chamber 8 is supported 'upon' the rotary grate-.bars 15. .Access to the ash pit 16 is provided through the door 17, and to the lire' through and below the its e movable grate ,through the door 1 8. Air for combustion is preferably supplied through thedraft door 19, but may alsobe supplied throughthe door 21.
In operating my improved heater, after a iire has beenl/Iindled on the grate bars fuel is fed in through the door 20 at the topof the fuel chamber 11. Air .for combustion .passs through the draft door 19 and through and beneath the movable grate 10 and also upward through the revolving grate bars 15, asis vindicated bythe arrows in Fig. 1. lo provide as complete control as possible of the draft, I have shown a damper 22 by which the air admitted throughthe vdraft door 19 may be regulated or cut off entirely from the gra-te 15. If it is desired to supply air separately through the grate 15, this may be admitted throughthe door 2 1. As the coal burns away in the combustion zone 8 the unburned coal from the magazine 11 above drops down and thereby supplies fresh coal for combustion. .The burning gases pass ol through the passages 7. between the water legs 6` into the combustion chamber 5 and thence -out through the ues 4 between and through the water sections 2.
`I have found that my improved form of heater is very efficient in service and may be advantageously employed with either line or coarse fuels, by reason ofthe free ldownward feed of the fuel, the'control of the drafts,
and the ability to widen ork narrow the eifective width of the combustion chamber. by moving the grate 10. The grate l() has also the advantage of being made in interitting sections Il()a secured in the frame 10b, Which permits readyreplacement of a section in case oneY .becomes warped or is otherwise dama ed. This` is accomplished. by con.- structing the frame 10b in sections releasably connectedtogether as indicated at 10. The removal of either end member of theframe 10b permits the sections 10a tozbe removed and interchanged or replaced;
The termsand expressions which I have emiloyedare used as termsofqdescription an not of limitation, and I have no intention, in the use of lsuch terms and'expres-V sions, of excluding any mechanical equivalents of .the features shown andgdescribed, or-l portions thereof, d but recognize Athat vaf so i icsA
rions structural modifications are possible within the scope of the invention claimed.
What lI claim is:
,1. In a sectional heater, the combination of a water front; a sectional, approximately vertically disposed grate ormin with' the water front one side of the fue chamber, said grate being adjustable in a generally horizontal direction independentlyof the water front; a bottom grate; a plurality of water legs opposite saidfrontand said vertical rate, said legs being spaced apart at t their ower ends opposite said grate to a ord draft passages, the parts so far enumerated forming 'a nel magazine and beneath this a cross-draft fire pot; and releasable means for fixingvsaid. vertical grate in adjusted positions suited to the nature and condition of the fuel, said means being capable of manipulation while the heater is in opera# tion.
2. In a heater, the combination of a plurality ofwater sections formed with passages for products of combustion leading past the lower portions of the sections; a Water front .opposed thereto and spaced therefrom-to form a gravity feeding fuel magazine; a sectional grate opposed to the lower portions of said water sections and hinged at i'ts upper margin to define a crossdrat ire pot beneathV said magazine and adjustablein its dimension in the direction of draft; and releasable means for fixinor the lower marginof said grate in adjusted positions, said means being capable of manipulation while the heater is in operation.
