Applietion alea aprn 10,1911. seralpNo. 620,094.

To all whom it may 001506151: Be it known that I, THOMAS A. DUNGAN,\ a citizen of the United States, residingV at Chicago, in t-he county of Cook and State of ing in the opposite direction from Fig; 1;

Fig. 4 is a section on the line 4 of Fig. 3; Fig. 5 isa section on the line 5 of Fig. 2; Fig. 6 is afdetailed transverse section through one of the cars on the plane indicated by the line 6 in Fig. 2, and Fig. 7 is a longitudinal section on the line 7 of Fig. 6.

Referring to the drawings, A 'is chamber, closed at one end by adoor A1, having in its top pipes A2 by means of which the running horizontal of the rails'B an products of distillation may be drawn off to a still.l The chamber A is preferably built of cement or concrete and it is lined or coated on its interior with an acid resisting compound, such as zinc fluates. In this way,

a retort 'suitable for the distillation of Wood is provided at a very low cost and with the maximum of strength and durability.

B are rails formmg a track upon'which the cars containing the Wood to beoperated unon can be run into and out of the retort. The rails B are carried b supports B1 so that they lie-a considerab e distanceA above t-he bottom of the chamber A, the purpose being to afford a space beneath the cars for theheating pipes. `l

The retort 1s heated Iby direct radiation from a flue in the following manner: C is a furnace, the smokeipe or exitipe thereof underneat the plane between the supports thereof B1, as shown at Cl in the drawings, and being thlen curved and' brought back at C2 along the side of the chamber, the extreme end of the pipe being turned' upwardly to a stack. The products of combustion are drawn through this 'long flue thus composed, in any approved mannen either by a forced draft, a suction-device or' the heated air may rise. slrable to place the. wood on end, that is,

by the use of a tall cliimneypas' may `be desired.

The cars, upon which the wood to be treated is'. placed, `may h-ave run-ning gears and frame-work of any desired sort. Each has, however,` areticulated floor made in theV form of a horizontal grate 4consisting of longitudinal rods d and transverseflat bars d* set on edge a'ndthrough-perforations 'in which Ithe rods d pass. There is thus pro- Which the Wood may rest and through whichv It is thought dewith its grain running vertically, and this reticulated floor provldes means for supporting the wood in that position. Under-l neath this reticulated Hoor in each car is a series of transversely extending troughs D,

each of which is made in t-he form of an S or vided in each car a reticulated surface lupon reverse curve, the troughs being so arranged l that one edge-of each overhangs the adjacent edge of the next, in the manner illustrated in Fig. 7, and all the troughs project beyond the side of t-he car on one-side and have their opposite-ends elevated so as to form inclines down which fluid will fiow. There is thus provided underneaththe fioor i' the cars pass, isa trough E over which the. ends of the car troughs D' project to dis- 1 charge their contentsA therein, a strainer or grating e being provided for the pur ose of catching and retaining any wo chips which may enter with the fluid products. The trough E is intersectedA by a partition E1 which comes nearly to the'bottom of the trough and a pipe E2 extends longitudinally1 ofthe trough on the opposite slde of the partition E1 from that on which the liquid enters. forations through which either air or steam may bei blown throughl the fluid, in the trough for the purpose of volatihzing as com letely as possible any of the lighter pro'uc'ts contained in the Huid. `The use of air or steam for this purpose, or both in alternation, may reduce certain chemical effects of a desirab e character, and the pres- 'ent apparatus is designed to afford means This' pipe contains a. series of-per- W noemer for producingsuch agitation ofthe fluid by direct contact with heated or unheated gas as the case may be. The partition El, it will be seen, operates as a dash-plate to prevent the iuid from being blown, in its agitation, out of the trough entirely. A valve E3 is provided through which the treated is of a simple and cheap character and has the desirable features already pointed out.

I am aware that considerable variation is possible in the details of the construction herein shown and described, and I therefore do not intend to-limit myself to such cony struction specifically; my intention being, in

the claims hereinafter set forth to specify all the novelty which is inherent in the construction .illustrated What ll claim as new and desire to secure by Letters Patent, is-

1. lnv a wood distilling apparatus a car having beneath. its contents a series of troughs each overhangin the nextv in the series and spaced there rom whereby the Huid falling from the wood will be caught by the troughs, while space is provided for the u ward passage of heated air.

2. llii a wood`distilling apparatus a car having beneath its Acontents a series of troughs each overhanging the next in the series and spaced therefrom wherebyv the fluid falling from the wood will becaught by the troughs, while space is provided for the upward passage of heated air, and a reticulated hoor above the troughs adapted -to support the contents of the car.

Ilin a wood distilling apparatus a `car having beneath its contents a series of troughs each overhanging the next in the series and lspaced' therefrom whereby the fluid falling from the wood will be caught by the troughs, while space is provided forthe upward passage of heated air, the troughs projecting from and being inclined toward one side of the car to discharge their contents, and a Ireticulated floor above the troughs for supporting the contents of the car.

5. In a wood distilling apparatus a car having beneath its contents a series of troughs each overhanging the next in the series and vspaced therefrom whereby .the Huid falling from the wood will be caught by the troughs, while space is provided for the upward passage of heated air, and a collecting trough into which all the car troughs discharge.

In a Wood distilling apparatus a car: having beneath its contents aA series of` beneath the ydischarge ends of the car`- troughs. 1

7. 1n combination a chamber, a trough on one side thereof, a .car for wood, means on the car tonconvey the Huid .exudng from the wood tothe troughs, a partition in the trough, and a pipe in the trough on the opposite side 'of the partition from the car, for the purpose set forth. ff

8. In combinationv a: chamber,a trough on one side thereof, a car for wood, means on the car to convey the fluid exuding from the wood to the trough, a partition in the trough, and a pipe in the trough on the op posite side of the partition from the car, and
