IMPROVEMENT- IN MALT-KlLNS.

The Schedule referred toiu these Letters Patent iand making part of the same.

I, CIL-mons Puttane BnneKHmrnn, of Cincinnati, in the county of l'iamilton .and State of Ohio, have invented certain Improvements in Malt-Kilns, of which the following is a specification,

Nature and Obcjcts ofthe Inrcniiont f vated some distance above the ground, thereby insuringa supply of pure and dryair to the interior ofthe apparatus, by which means its cliicicncy is increased vand the labor of attending'it.diminished.

The second part of my invention relates to that vpart of the kiln termed the hopper, which, surrounding the cupola, extends up to the perforated floor, and which serves to conduct the heated air to the grain that is to be dried; and y The improvement consists in constructing thispart of the apparatus of metallic sheets or plates, having nWarLlIy-prOjecting iianges for supporting a lining composed of cement, tire-clay, or some other suitable plastic material, which will prevent the radiatiml of heat.

General Description with` Ltyi/reizco lo the Drawing/ Figure l is a vertical section of a malt-kiln embodying my improvements, one of the registers for regulating the supply of air heilig represented open and the other-closed.

Figure 2 is a section through a portion of the kiln taken at the line a'.

Figure 3 is a perspective view of a part of the metal casing or shell of the hopper, with a portion of the cement lining removed therefrom.

A represents thel furnace or-cupola, having the eustomary ash-pit- B, lire-chamber G, land vertical tine l), up which the heat ascends from thc tire in said chamber U.

The pit D and tire-chamber U are provided, respectively, with doors l: b and co', for the purpose ot'rcgulating the supply of air to the furnace, and to allow the replenishing of the fuel in the same.

Located a suitable distance above the yupper end of ue D is the customary slab or lintel E, which compels thc heated air arising from said Hue to discharge itself laterally int-o the kiln, and noiI to take a direct central passage through the same.

The sloping4 top o of this slab or plate causes the deflection of fsprouts, which may fall through the perforated floor of the drying-room, and prevents them dropping into the mouth ot the furnace.

The walls ofthe cupola, after being carried up a propel' height, are diminished in thickness, so as to form a ledge, l", which serves as a foundation for a heavy casting or bed-plate, f, that surrounds the cupola on all four sides.

Projecting outwardly from this bed-plate are arms, 1i, for the support of a rim, I, having a shoulder, i, for a purpose which will presently appear. p

Between tho arms H are openings J, through which fresh air ilows to the interior of the apparatus, and the supply is regulated by means of registers, K, which are hinged at tfto the rim I.

The opening or closing ofthe'sc registers is controlled by cords or chains L.

Resting upon the ledge i, and arranged so as to incline outwardly from the cupola, is a number of metallicplates, M, preferably of sheet-iron, whose lower` edges are bent so as to form inwardlyprojecting tianges, Ju, that serve to support a lining, N. This lining may be composed of cement, tire-clay, plaster of Paris, or any other suitable refractory material that is a non-cmuluctor of heat and that can be applicd'in a plastic condition. This v filling is cheap, readily applied, and is, in every respect, superior to the. expensive and heavy brick-work lining which has heretofore been employed in this part of a malt-kiln.

lhe metallic jacket or shell M ofthe hopper, if preferred, maybe stiffened by angle-iron ribs, O, tha-t can extend from the top of rim I to thcpcrtin'ated ioor l of Jthe drying-room.

rlhe sheet-metal plates composing the shell, together with their angle-iron ribs, are united by rivets T.

'lhe oorl extends completely across the mouth of the kiln and rest-s upon beams lt.

Bins or other receptacles, S, may be placed at the sides of the furnace for the purpose of rcccivingthe sprouts which may be deflected from lintel E and fall through openings J, and suitable troughs may be arranged around the cupolaJ for conducting the sprouts into said receptacles.

In all kilns which have heretotore been built it has been customary to locate the air-ducts in the walls of the cupola, thereby increasing thc dimensions and cost of the same, and at the same time causing the kiln to occupy a large amount of valuable space, besides which, the openings that admitted air to said ducts were always situated ucar the ground, where the air is more or less impure.

It will be secu that the arrangement of air-openings .T renders my kiln free from all these defects.

Another serious objection to thc old-tiishioned-kiln consists in the arrangement of heavy beams, wooden sheathing, and interior brick-lining, for which I have substituted the angle-iron ribs O, sheet-metal case M, and plastic filling N, thereby diminishing the weight, reducing the dost of construction, :unl rendering the kiln perfect-l y fire-proof.,v

If desired, `doors can be meule in the plates m, so as to afford access to the interior of the hopper for the purpose of inspecting and cleaning the-seme.

Cla-ilus.

I claim aslnew and of my inventionl. A malt-kiln, having the external and elevated air-inlets J, which :ire closztble by registers K, or their equivalents, substantially as herein described.

2. The combination' of' the sheet-metal case M M and plastic filling N, for the object herein set forth.

In testimony of which invention I hereunto set my hand.
