.To all whom, it 11i/ay concern:

Be it known that I, GEORGE W. SHARER, a

citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Inl diana, have invented certain new and useful Improvenients in Driers; and Idohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to. make and use the same.

My" invention relates, generally, to driers which can be uscd'ifor drying lumber, brick, pottery, terra-cotta, terra-cotta lumber,` and other similar substances, and particularly relates to that class in which terra-cotta, lterracotta castings, and terra cotta lumber and bricks are dried. p

.The object of my invention is to improve .thegeneralconstruction of driers of this kind;

and the invention therefore consist-s of constructions and combinations, all as will hereinafter be described and claimed, reference being had to the accompanying drawings, in which- Figure 1 represents a perspective with parts broken away to show the construction; Fig. 2, a horizontal section, the upper right-hand part being through the drying chamber, the. up per4 lefthand part through the fines, and the lower part through the furnaces on line :r x, Fig. 3; Fig. 3, a front elevation with parts broken away to sh'owthe furnace and flues in section; Fig. 4, a longitudinal section through one of the furnaces and one of its fines and taken on line 4 4, Fig."2; Fig. 5, a longitudinal section on-lines 5 5, Fig. 2; Fig.'6, a longitudinal section on line 6 6, Fig. 2;' Fig. 7,*a transverse section ofthe furnace, showing the mannerof using petroleum as a fuel; and Fig. V8, va longitudinalsection on line 8 8, Fig. 7.

The drying-'chambers A, which' may be of any desired number,separated from each other by' partitions A', which rest upon longitudinal walls A2 under the floor of the drier,'are of or.- dinary construction. Beneath the dryingchamber are the lines a, a', and a2, formed by the longitudinal division`- walls A2 and tine-V walls A3, the iloorA of the drying-chambers,

and the bottom or foundation of the drien These flues open atl the rear end into a transversctlue, A, which'is connected at its ends .main passagec3 in the wall B leads. ter passage follows the inclination of the flue,

V.furnace is provided with two sets of ues separated from each other by the hollow divisional walls, and the sets of dues are subdivided by means of a vlongitudinal partition, b, forniing individual or sub filles bb2, and terminate in chamber As at apoint opposite to the iiuel c under the drier. The object -of` this construction is to concentrate the heat of the products of combustion upon the walls containing the air-ducts and vthen disseminate it equally thetlues a, c', anda, the transverse due A5', and chimneys'Al, placed at each end' of the latter, so as t make the tlues draw equally.

The sub-fines bvb2 open into the distributing- .under the drier by means of the chamber A8,`

chamber B in the back partof the furnace B?, v

which is sunk partly or wholly below the surface and provided iu front with the workingpit 13". The space between it and the drier is also slightly depressed for the transfertrack for the truck to be moved from -the drier.

In the walls which divide the furnaces are formed the air-ducts O and C', separated from each4 other by the tile G2.- The ducts C, except those at the ends, as shown in Fig. 2, are formed oftwo separate passages, c c', joined together by the transverse passage c, from which the This lat andthe upper end terminates ina passage, C3, in the drier partition-walls, (see Figs. 1,4, and

.5,) so that the heat will be equally distributed 'to the drying-chambersin each side of the wall.

Thev lower flue, C', is formed of passages c* c5 c", which respectively correspond to and areA formed underneath the passages c, c', and c. Passage c is connected with a transverse passage, cl, bya short passage, cs, immediately un der passage ci.; This passage is connected at each end with the passages ci in the walls B' and opens into 'the-transverse passageCitseeFi s.

1 andlyin the drier partition-walls. Byt is construction it will be seen that I am enabled to heat thea'ir to a higlrtemneraturc and evenly distribute it in the drying-chambers, and also heat the bottom of the drier evenly by means of the'producls of combustion. If desired, a stca1n-pipc, D, may be placed in the drier. This construction of drier will dry any ordinary article, such as lumber, brick, terra-cotta, terra-cotta castings, terra-,cotta lumber, and similar articles. v

In Figs. l, 2, 3, andi the furnace is shown with a grate, and in Figs. 7 and 8 a device is shown whereby petroleum orhydrocarbon can he substituted for the fuel used in the furnace having a grate.

E in Fig. 7 represents a pan having a. noz1 rdeepening` in its bottom and connected-with a water-supplying device by means of a pipe, l', which iucloses a second pipe, E2, through which oil is supplied to the pan F. The water und oil pipes are supplied with suitable cocks to regulate thedowinto the pan. In the walls of the furnace are formed air-passages, which lead upwardly into a chamber, E3, that opens into the fire-box. .This chamber is divided 'into compartments by bricks E, ar-

ranged at suitable intervals, so that the air ad! mitted to the [ire-box will be in jets.

Vhat I cla-im as new isv In a drier, the combination of the dryingehambers having fines under the bottoms, fu rnaces having;- lues communicating with the flues bencath'the dryingchambers, the airducts C and C' in the sidewalls of the furnaces. and air-ducts c3 und c", formed in the divisional walls of the furnace-lines and delivering` into the air-inlets of the d :ying-chambers, and the air-ducts c being; connected with duct (l by lateral passages, and air-duets c being connected together b v the d uct ci, and by it with passage or duct C', substantially us described.

In testimony whereof l. uiix my signature iu presence of two witnesses.
