GHARCQAlL-KILN.

To all whom it may concern Be it known that l, ALFRED RQWEBEL- any, a subject of, the King of Great Britain, residing at Spittlegate lron JVorks, Grantham, liinco'lnshire, England, have invented new and useful Improvements in Charcoal-Kilns, of which the following is a specification.

My invention relates to kilns for charcoal burning.

Charcoal kilns have already been proposed which comprise a body having a series of inspection and air holes distributed over it in a staggered formation, and provided with a charging opening at the top and a conical bottom fitted with a sliding door serving a double function, namely, that of controlling the discharge of the contents of kiln, andof the inlet of air into the bottom of the latter. l'n suchkilns it is usual to depend upon the pieces of wood jamming in the conical bottom to prevent their falling through the kiln when the slidingdoor is open or partially open.

New, according to my invention ll make use of a kiln which is composed of a body having a conical bottom as above described, the said bottom being furnished ,With'a discharge opening which is designed to be closed by a hinged drop-down door, which said door merely serves the pi. "pose of controlling the discharge of the charcoal. Above the door the conical bottom is provided with a grate upon which the wood or other material rests and having sliding bars, or any other suitable devices, so as to control the flow therethrough of air which enters laterally the space between the said bars and the aforesaid door.

The body of the kiln is preferably made in sections for easy handling and erection and is furnished with a series of. air inlet holes which may advantageously serve as inspection holes as above described, and these holes may be fitted with means, such as doors, whereby they may be opened or closed as desired. These holes may open directly into the interior of thekiln, or they may open into annular ringsthemselves in communication with the interior ofthe kiln. or, the introduction of air to the body of the kiln maybe controlled in any other desired manner.

To enable my invention to be fully under- Specification of Letters Patent.

Application filed February 2, 1915. Serial No. 5,761.

howing the discharge outlet opened. Fig. 0 is a view similar to Fig. 3 illustrating a modification, and 6 is a sectional plan thereof. Figs. 7 and 8 are a front view and a vertical section, respectively, drawn ectional view of the lower part thereof to a larger scale illustrating one of the draught regulating doors, and Figs. 9 and 10 are two views similar to Figs. 7 and. 8 of a modification hereinafter described 66 represents the body'of the kiln, which preferably made in sections as appears rom Figs. 1, and 5, the object of this construction being to facilitate the transport, erection and handling of the apparatus, the said sections being advantageously connected together in the manner hereinafter described.

72 is the conical bottom of the body a and c is the discharge opening which is provided at the lower ape end of the said conical portion 5.

cl is the door for controlling the discharge of the charcoal, the said door being of the drop down type and being hinged at e to a frame 7 provided externally upon the bottom of the body a of the kiln below the dlscharge opening 0.

g are the fire-bars which form a grate upon which the Wood or other material rests, the said bars being located above the door (Z and being arranged so that they can slide in holes 7a in the aforesaid frame upon which the door cl is hinged. The holes it constitute inlets for air which thus enters laterally into the space 71. between the discharge opening a and the door (Z when the latter is closed.

i are the inlet holes which are formed in the body a of the kiln and, in the construc .trated in Figs. 9 and 10, such arrangement comprising a horizontally sliding door a whichmoves in guides in a frameo attached to the'outside of the kiln body adjacent to the opening z', similarly to the frames Z.

The air inlet, whatever be the nature of the door or the equivalent by means of which the passage of air therethrough may be regulated, may open directly into the interior of the kiln body, as shown in the construction illustrated'in Figs. '1 to 4,01 they may open into annular passages ,7) as in the construction shown in Figs. 5 and 6. These annular passages 29 are formed in the body of the kiln and open at intervals, as shown at Q into the interior of the kiln. I v

The kiln is utilized as follows, that is to say, the body has stacked Within it the wood to be converted to charcoal, and the door (Z is opened and the lire-bars g placedin the position shown in F 3. the wood i then ignited through the open bottom and when the combustion has started the door d is closed and all or any of the fire-bars can be drawnxont'or partially drawn out, as re quired, for properly regulating the admis sion of air through theholes 7t mtothe botraces i5 tom of the kiln body independently of the door (Z; also, as will be understood, the air inlets i to the body of the kiln are opened to an extent necessary to eifect' the proper control of the charooaling operation.

Claims.

1. A charcoal kiln comprising a body,,and a conical bottom provided with adischarge opening, a door controlling the said discharge opening, a. grate located above the door and beneath the discharge opening and means for regulating the inlet of air inclependently of the door.

9,. A charcoal kiln comprising a'body, and a conical bottom provided with a discharge opening, a door controlling the said discharge pening, a, grate located above the door and beneath the discharge opening and means for re ulating the inlet of air through the grate independently of the door. 3. A charcoal kiln comprising a body, a conical bottom to the said body provided with a'discharge opening, the said bottom having a grate located beneath said discharge opening, a discharge door located" below the grate and means whereby the ad- .mission'of air through the grate can be regulated independently of the door.

i. In charcoal kilns of 'tliekmd descrlbed,

the combination with the kiln body, of a conical bottom therefor, a grate having a 79 plurality of fire bars slidable in holes in a frame below the said grate, and a drop-down. door hinged to said frame below said holes.
