TO-WHOM IT MAY, CONCERN: l

Be it known that I, W'ILLIAM B. yTruasnwnnr.,ot` the city and 'county of Albany, and State ot- New York,

have invented a certairi new and useful Improvement in Stoves, particularly adapted to the' construction of cookingfstoves for thev burning of bituminous coal; and I do hereby declare thatA the following is a full land 'exact description thereof, reference being had to tlle'accompanying drawings, makinga part of this specification, the sameletter in each of Athe several figures marking the same part of the stove. In the accompanying drawingsv f l Figurel lis a perspective vview of my invention, with hearth swung o' from the stove. Figure 2 is a vertical section through the centre of the stove from front to back. Figure 3 is a horizontall section of the dre-chamber, taken on theplane of the red lino T in g. 2.4 v -The nature and object of my improvement are threefold: first, I seek, by the proper application of air to the several parts of the iire, or its introduction into the re-chamber, to burn more perfectly bituminous coal in .cooking-stoves, so asto consume the smoke and gases'which arise therefrom during the ordinary process-.oi`

burning; second, to so construct stoves as to avoid rovertible dues; third, to separate the coal from ,the ashes and refuse matter which have dropped from the dre-chamber with as little trouble and inconvenience as possible;

all of which I have accomplished in the improvement hereinafter particularly described. l. 5

The great desideratunl'in the construction of a stove for the perfect combustion of' the fuel employed is to so apply the air, and in such quantities, as to supply necessary quantities of oxygen at the particular points needed for combustion'. The' quantity mustbe suiicient to furnish the necessary amount of oxygen, and at the same time not toomuch to absorb the 'heat and choke the passage through the escape-lines, thus affecting' unfavorably the draught of the stove.

In my improvement lI have carefully providedv forthe appropriate supply of air atfthe points of combustion.` l

By anlexamination'oi figs. I and 2, my provisions in these respects will be seen. l i

In iig. 1, these 'provisions' are seen in the tubes *an a a, as seen in the back of the 'irmpot through -the opening in 'the top of the stove. These tubes are perforated as represented by the black points or dots, as seen in iig. 1. 'The object ofthese perforations is to allon'j the air which is admitted to these tubes to escape into the fire-pot in small streams orjets among and upon the solid burning fuel. ;'I'his is to supply that pai-tof theiuel lying against the back'part of tlie fire-pot ivlth air, which is admitted to these tubesthrou'gh an opening in the side of thestove seen atv-K in iig. 1. Airis also admitted to the frontand upper surface oi' theburning fuelin the {ire-pot through apass'age formed by plates F and v, and bythe grate G, as seen and exhibited at 'm andf, in g. 2, the ceurseoi the air being indicated by the red arrows atm and j'. The air is supplied to these openings through damper-plates seen under the feed-place B in iig. 1, and represented atdainp'er w in g. 2. Air is applied to the Jrire-chamber at the back part oithc fire-chamber, and at' the upper partrot the fuel, through openingsI between the plates seen in iig. 1, at n, and represented in iig. 2 by the red arrow enter 'irig theiirc-potat The air is supplied to4 these openings by means of 'a chamber connecting with. the same,

having its outward orifice atj, as seen at iig. 1, as well also as by means oi' air from the tubes in the'baek of Athe` repot, as seen in fig.. 2, and represented by tube a. Air is also supplied at -the Vbottom of the repot through tho grate Gr, as seen in 2.' In this manner every'part of the f uel 'in the tire-pot is supplied with the requisite amount of oxygen to facilitate the combustion thereof.

I construct ary-stove, to accomplish my second purpose, that is, to avoid revertible fines,` as follows:I This is particularly'exhibited 'in iig. 2, 4:representing a verticalfsectionoi the stove, in'whicli are seen thefeed-plaee BA, the tire-'chamber A,'the escape of the products'of combustion, as indicated by the black arrows, from the top of the re-chambcr into the space O formed by -the top of the oven D-and the top' plate and the covers of the "stove, connecting wtlrthe escape-due at O, forming a heating-current over the top of the oven. The products of combustion also' pass outbetween' the tubes forming the back of the dire-pot, entering 'the space E; between 'theire-pot and the oven-1.), and passing thence underneath and up the back of the oven, connecting with the SmQeSape-ilue at O, thus forming a heating-current underneath andaround the sides of 'the oven. In this way my fins are directkand yet they encircle the oven, heating equally every part thereof.

The third branch of my improvement consists in separating the coal from the refuse matters which have dropped from the fire-chamber upon und into the separator. This rseparator or sifter isseen' in figs.. 1 and 2,V and is represented by letter L. This siftec is situated benenthlthc grate'G to receive the coals, ashes, und other refuse I'nattcr which may fall or be dumpedrupon it. By means of a. hook acting upon the' shaft Z, the sifter may be vibruted to separate the ashes from th'e cool. VAfter thissiftinghas takenplace, the sifter is dumped into the box M, by means of o lever acting upon the shnft Z; the fishes are collected in the box4 N.

Thus the coals axc sepm'stcd from the ashes without any inconvenience, and with little labor.

In the drawing, iig. 1, H is the hearth of the stove, lmode separate from the stove, und attached to it by means of n hinge, so that it maybe closed and opened at pleasure. ,The box `for the coal separated from th'e ushers is placed. in the hearthH, as seen in iig. 1, ondrepresentcd in fig. 2, at M. p p

Having thus fully described my imprQ ve111ent,-[ will proceed to describe what I cicim ns my invention, and desire to secure by Letters Patent. l 1. I claim grate Gr, combined with plates 'F und v, constructed substantially in the manner and for the purpose above described. p V

' 2. I claim grate Gr, plates F and v, in combination with plates d and e, for introducing cir et m end'n, constructed substantially in tho manner and for vthe purposes above described.

3. I claim the irefchnmber, constructed as nabovc, in combina-tion'wth the sfter L, snbstantially in the manner and for theV purposes above described. I

4..I claiml the sifter L, in combination with the boxes M und N and the grote-G, substantially in the manner and for the purpose above described. J V

5. I claim the hearth H, constructed substantially in the manner und for the purpose herein described.
