ITo all whom tt may concern .f

Be it known that l, WALTER A. LOVELAGE, a citizen of the United States,residing at West De Pere, in the county of Brown and Slate of Wisconsin, have invented new and useful Iniproveinents in Charcoal-Kilns, of which the following is a speeitication.

rlhis invention relates to that class of charcoal-kilns in which the kiln consists ofa hood adapted to be seated upon a foundation and provided with a door-and with smoke and steam escape pipes. Y

My improvement is directed to the construe.

tion ofthe foundation for such hood; and it' In the drawin s, Ifieure 1 is a side eleva-- tion ofthe kiln and its foundation. Fig. 2 is a vertical section through the saine. Fig. Bis a top view of the foundation. Fig.4 isa horizontal section through the two hoods that form the kiln.

ln carrying ont my invention I construct a brick or stone foundation, A, for the kiln to rest upon. .i central furnace ordre-chamber, ll, from which the passages b b lead to the sides of the foundation,and at the outer ends of these passages l provide hinged doors C, with suitable fastenings, c, for locking the doors when closed. Each one of these doors is provided with an opening which can be either partially or entirelycloscd by a pivoted valve or damper, D, so as to regulate the draft, and consequently vary the intensity of the heat within the furnace and kiln.

The tire-chamber is provided with a suitable grate, D', and is closed at the top by a door, E, which can be hinged orv pivoted or arranged to slide upon the foundation, as preferred, the method herein shown of attaching the door being by pivoting the same at one of its ends. The kiln which is supported upon this foundation comprises an inner and an outer hood or casing, both of which are closed at their top and sides andopen atthe bottom. These hoods This foundation is provided with through their lianges. The inner hood, F,

or walk'a, which extends around the upper edge of the foundation, this said wall serving to maintain the hood upon the foundation.'

hood, is also formed with a base-llangarg, which, when the two hoods are in position,

proper, are secured together by means of bolts which passthrough theirtlan ges,and are simply seated on the foundation. By thus arranging as a stationary or immovable kiln it can be and then relieved ot' its contentsthrough the discharge g2, located in the side ofthe kiln near its base. These feed and discharge openings are formed through both hoods, with a tlange,

the inner hood, so that said iiange will .constitute a Achute or passage between the hoods. Said feed and discharge openings are closed by suitable doors, H, which can he opened when the material is to be fed into or removed from the kiln. These hoods are of such relainch (or more) is left between the two. This space ispilled with ashes or any other good non-conductor of heat, which will prevent the exclude external air, thereby rendering it impossible for the wood or coal within the kiln side hood will never become too hot tobe handled.

'lhe foundation is provided with a series of ilues, K, for conveying the hot air from the ranged to branch out laterally from the replace and then extend upward to the top of the foundation. The foundation is also pro'- vided 'with a series et' dues, L, for the escape ot' smoke and steam from the kiln. These smokeand steam escape dues L extend from are each composed of sections f, of sheet metal, flanged along their edges and secured to. gether by suitable bolts or rivets passing which is provided with a tla.nge,f, at its base,v is seated upon the foundation A, within a ridge vThe outer hood, G, which incloses the inner lire-place into the kiln, thcsedues being ar-` rests upon the base-Bange ot' the inner hood. These two hoods, which compose the kilnl the kiln it canbe raised bodily and transpo'rlsed from one foundation to another; but if used' filled through-the feed-opening g at the top,

g3, around the opening in either the'outer'or tive size that a space, I, ,of about one-halt` an radiation of heat from the kiln and ett'ectually IOO 9o to ignite. lt will also be found that theout- The lines K and L serve as ventilators. Thei hot air from the fireplace passes up through the hot-air lines K into the kiln,.where it is equally distributed, while the foul air and: smoke pass down and out froni the kiln through the escapepipes L. By lthis mode of ventilatingand also ofconducting the hot air from the tire-place, whichis separated from the` kiln and connected therewith only by the fines, the wood or coal within the kilnwill be charred bnl. not ignited, since` the Haines will `not roach the material in the kiln.

Itwill-a'lso .be found that after the fire has been pnt out drremoved from the fire-placeI the ltiln will cool rapidlysay iu from three to six hoursthe ilues K and L being open so as to admit cool air.

The ltilrrcan be made ot' any desired capacity, and it lwill not crack or warp, since the blaze does not reach either. the inside or the outside hood.

During the chart-ing process the inside hood will become 'coated with wo0d-tar, which will further serve to render the kiln air-tight and also prevent it from oxidation. `Finally, the` quality of the coal will be improved, the charring being accomplished with the least possible amount of air, and hence the carbon ot' the coal will be retained, and not; burned out.

What; I claim is- 1. The combination ofthe kiln-hood 'with the' 'foundation A, provided withan inclosed eenatmosphere when thehood is closed, said members being constructed and organized substantiall5r as described.

2.4'1`1he combination,

in a charcoal-kiln, of 5o anl open-bottom hood, in which the wood to be charred is placed, withthe foundation A, upon which the hood is seated, formed with. a central fire-place, B, closed at the top by a suit,- able door and having' one or more side passages, b, a. series of fines, K, radiating from the sides of the tire-place and leading up through the foundation, so as to open into the hood, and a second seresot exit-flues, L,lead ing from the top ot' said foundation to poi'nts 'along'its sides, st ibstantially as described.

In testimony whereot'l have h erennto set my hand in the presence ot' two subscribing witnesses.-

WALTER A. LOVELAGE.
