RETORT.

Specification of Letters Patent. i

Application filed December 16, 1911. Serial No. 666,309.

lPatented Sept. 30, 1913..

.To all whom t may conce/rn `Be 1t known that'we, Cuantas B. Dumm V'and Mano DAnmN, citizens of the United States, residing at Bellingham, in the county of WVhatcom and State of Washington, have invented a certain new and useful Improvelment in. Retorts, of which the following is a specification.

@ur invention relates to improvements in` material may enter one end of such retort.

and each of such loads, in its passage therethrough, successively be subjected to varying conditions of heat during its progress to .the other'end from which it emerfres in the form of 'nearly pure carbon; its dit'ferent kinds of distillable matter having each been separately extracted at a di'lferent point within such retort during its journey therethrough; and the object of our improvement is to provide a single structure which shall constitute a retort embodying a. longitudinal succession of infercommunicating compartments, within each of which compartments the material to be retorted independently may be subjected to a desired treatment, and which shall be simple vin construction, durable and have a high fuel efficiency. lVe attain this object by devices illustrated inI the accompanying drawing in which-- Figure 1 is a (iliagrammatical view in side elevation indicating some of the essential features of our invention. Fig. Q is a diagram in vertical-section on lines www of Fig. 1 of same. ,.Fig. 3 ,is a diagram in verticalsecti'on on line .fc-a' of Fig. 1 of same. Fig. 4 is a diagram in verticahsecticn on line y/e-y/ of same. Fig. 5 is a diagram in vertical-section on line and F ig. 6 is a diagram ot' a plan-view of our invention.

Like reference numbers indicate like parts throughout the'drawings.

Referring `to Fig. 1., therein are shown sections 9-10-11-12 and 13 of a retort, which sections are connected together by expension joints 1/1to form a single structure. The ends of'said retort are each provided With-a gate 15, which is adapted to be raised or lowered to open orclose it by force acting through a piston rod-16 which piston rod 16 is indicated in Fig. 1 as extending upward from each end of said retort. 'I'Iydraulic or other suitable devices may be employed such "as the cylinders 17 to actuate such piston rod 1G or other device for controlling said gate. Each section between adjacent joints 11 is formed to have a shape shown in cross-section by Fig. Q. 11m-152 and 13 preferably may be made of iron plates or of steel plates, though common brick, tire brick or other suitable material might be used in some cases. The sections 5)-1()-1ll2 and 13 are shown in Fig. 1 as being disposed to rest upon a number of rollers 1S which rollers serve to permit free longitudinal movement of said sections due to expansion or contraction thereof and which are disposed upon a series of inclined girders 20, which extend between and are supported by the gate supports 1t), whereby one end of the retort is higher than the other to provide drainage. Leading into the tops ot' sections 9 and 13 are the pipes 21 which may be connected with a source of live steam not shown. At the bottom of the lower end of each of sections 10-11 and 12 are disposed drain pipes through which may pass the heavier matter which may exude from the material operated upon.

From the top of section 10 are two outlet passages 22.3 which are connected by suitable elbows, pipes and a T to a pipe 2li which may conduct distilled matter to a receptacle not shown. Also from the tops of sections 11 and 1Q are other systems of pipes each system comprising four upright pipes 25 having closed tops and :from near each of which tops extends downwardly at an angle of about degrees a pipe 26 which is connected with one of four upright stand-pipes Qi' which are all connected at their top ends with a horizontal pipe 28 from which a pipe Q9 may lead to a receptacle not shown, for lighter distilled products. Each of the stand-pipes QT is provided with a smaller outlet pipe 30 through which heavier prod- `ucts of distillation may flowrto a suitable receptacle as indicated in Figs. 4 and 5. The stand-pipes 27 are each further provided with a smaller pipe 31 which enters at the top' thereof and projects through its side -near its bottom is indicated in Figs. 4 and `5 'by dotted lines. This smaller pipe 31 1n practical operation is supplied with cold water whereby it may serve to cool and con- 'lhe said sections 9-10- 4nets are subjected to the presence of the while the most volatile products 4rise and HOW to another suitable receptacle lthroinqh `pipe 29. Again, after a suitable period of time the car 40 is moved in a similar manner into section l2 which is oit still higher teinperature and within vwhich the material in car 40 is subjected to similar treatment while the products exuding` from such material are disposed of in a manner similar to that which occurred in section number 11. After the material has remained siifliciently long 1in section 12 it is inducted into section 13 where it is subjectedto live steam which may enter through pipe 2l, whichlive steam serves to cool the material in car 4() which now consists almost wholly ot' pure carbon whereby its temperature. is reduced below the point of combustion whereupon the car may be caused to emerge from the lower end of the retort to 4dispose of its carhonized residuiiin. This operation may he continuous; that is, as fast as ears are moved from one section'into' another they may be replaced t by other loaded cars, thus fresh carloads of raw' material successively are pushed into the live steam ent ance section 9 and successively passing through the several sections 10--1'1 and 12 thence pass successively from section 13. 4

'lhe vapors 'which pass :trom the 'pipe Qt leading;` from section l() to a suitable receptacle contain volatile constituents in a nearly pure, unliurned, non-einpyreuniatic and 'eas- `ily reiiuahle state. The vapors troni retort section number 11 passing through the condenser standard-pipes 27' tcivc up the greater part of the heavy tar constituents which have always caused trouble in sulisequent re- -neinen't, such heavy tar constituents draining' :from pipes 30. Such vapors, atter travcling,` through the standard-pipes Q7, are

thus in a more easily retinable form. y Vapors from section l2 are treated in an identical manner witlrthose from section l1. VVl'ien desired an exhaust pump may be employed in an obvious manner to hasten the removal ot vapors from any ot the sections` It will be observed that wood or other ma terial when placed within the car -i-O permits the' pitch and tar to trickle downward and drip on to the less heated floor bottoni to be `drained oft without, decomposition. The hot tar condensers associated with pipes` QG and standard-pipes27 greatly aid a subsequent refinement of volatile products.

Manitestly our retort may he made to enibody any number of sections of any length that may be commercially desirable and it may be oi any desired shape in cross-section, but preferably narrow, as the heat is applied to its sides by furnaces and tlues and by supcrhcated steam pipes to heatquickly and thoroughly the material treated; and the bottom of the retort is thus maintained at `such lower temperature as will prevent injury by over heating of the dripping's from the material treated.

Of course, the cars 40 may he modified in plan of construction, as for instance, they might have wlieels to run on a track which might be substituted tor the rollers on the floor of the retort and the sides and tops ot such cars 4 0 might be ot dilterent :toi-ins.

W'hat we claim is:

l. A retort having compartment sections, a (lue disposed over the central ones of said sections, the inlet portion ot said flue beingr enlarged, steam pipes conducted through said (lue and intcriorly ot a portion of said sections and exhausting into the terminal one thereof positioned within said flue, a fui.'- nace positioned within thc enlarged inlet portion ol the tlue, and an exhaust outlet pipe for said tlue.

Q. A retort consisting,l oi a plurality ot' compartment sections, steam pipes entering the terminal ones ot' said sections, a flue disposed over the remaining central ones of said sections, the inlet portion ot said flue being enlarged. a t'urnace positioned within said enlarged i'luo portion and surrounding one oi said sections, an exhaust outlet pipe at the opposite end ot said flue, steam pipes extending through said enlarged flue portion and within said turnace, said steam pipes passing throupjh the middle one ot` said flue inclosed sections and entering and exhaustin r within the section lying.,r adjacent the flue exhaust outlet.

In witness whercot', we hereunto subscribe our naines this 25th day ot' November A. l). 1011.
