Be it known that I, THoMAs PARKiiR, a

subject of the King of Great Britain and Ireland, residing atgSevern House, Ironbridge, 1 Salop; England, "have invented certain new and useful Improyements-Relating tpatl e; Destructive Distillation, of i'BitumihousgC-oal or Similar carbonaceous Subsimilarcarbonaceous substance and par- 'HNQ. 865,724 26/1/07 that is to-sayto an apparatus for the partial destructive dist1llat1onof coal at a low temperature ar rested at the pointwhen illuminating jgas f The invention has for its object to effect such a distillation. with economy and efli ;.c1.en cy and m such manneras to produce a.

thoroughly homogeneous product Without any wastage"duev to insu-flicient distillation of any part of themass. I

According'to the invention IemplOy fine coal which is chargedinto vertical retorts so that'its volume is sufficient completely to 30f fill the retorts and so that when subjected 1 to heat in the process. of distillation. the charge is compressed and. may fall out of the .retorts and thus a fuel produced that is hard and denser I effect the distillation of such substance within vertical retorts of small diameter, that is to sayof about from A to '6 inches internal diameter and I apply {heat uniformly around the retorts'so that tthe distillation takes'place toward the cen- 4O ter of the charge in the retortsby gradual penetration and" the whole mass. uniformly t tdistilled 'so that a homogeneous and uni-' iiorm product results with no wastage and a without the necessaryinsuflicient distillation and carried withincommon, top and-bottom fittings. The topfitting .I providerwith-a series of apertures for the reception of the ends of the retort tubes, and centrally above the. series of" retort tubes ,I arrange the charging aperture withinv a surmountin hood so that allrth'etubes may be fille ices, of. whiclrthefollowing is a specifil l l .I I l This invention"relates to the partial destructive distillation of bituminous coal or.

through.- same charging apert-ure, and

p An apparatus "for use in carrying out the invention is-illustra'ted in the accompanying drawings in hichi Figure 1 represents in sectional elevation plan corresponding thereto on the line m-y Fig. 1. r i

little distance below the extremity, so that the flange may engage-on the under-side of the top fitting e,' there being a clearance provided at flbetweenthe' upper end of the rethe fitting into whichlsuitable luting may be introducedso that thus the upper ends position with a gas-tight joint) t The. retort tubes a are provided with a taper bore of a diameter at their u per extremitiesv ofabo'ut 4-} inches and a diameter of about inch more at their lower extremities and thejlower extremity ofeach tube I advantageously form witha conical face 12 for 'se ating1upon a corresponding conical face provided on an inwardly extending flange g protruding in the respective apertureof the bottom fitting 11. Upon the top fitting @I provide a hood :5 whichadvantagcously contracts'inwardly toward its upper extremity leaving an aperture 1: sutli .ciently large for charging the several retort tubes carried in the respective set of top and bottom fittings, and this aperture k is closed closed gas tight by means of a lever m pivoted 1n a -bracket on the hood, whichcover is pivotally carried by the lever m, and is tightly closed by means of a bolt and nut. An outlet 0 is formed laterally in the hood for the gas which passes up from all the tubes of the battery unit.

hinged at s, and capable of being brought down by suitable means forthe discharge of 'the mass after partial distillation.

-- The retort tubes are so disposed with relation-to each'other as to leave interstitial In carrying" the invention into effect I. provide the upper extremity b of .the retort tubes" awith an outwardly extending shoulder d andalaterally extending flange esom'e of the, retort tubes may be firmly secured inf by 'a cover Z which may advantageously be Qspeeiiication of- Letters Patent; Patented N p V, 23, 1909. a flicatioi fiieamay 3,1909, Serial No. 493,685. f

-- at theside ottlie hood or top fitting I ara unit battery of retort tubes, and Fig. 2 is a Y tort tubes a and the'respective aperture in The respective apertures 1n thelbottom fitting'h are closed by a common cover plate 1" spaces through whichthe hot gaseinployed may be uniformly heated by them.

for heating them may. pass so thatthetubes mount batteries of retort tubes providedas hereinbefore described within a furnace I casing orsetting and I heat the retort tubes externally by means of producer gas or any. other gaseous fuel, the gasbeing led through the furnace casing or setting. i

I charge the respective batteries ofretort tubes with coal which I'fi-rst pulverize prefv erably by passing the coal between grinding charging '15 of the sire'to secure by Letters atent is rollers, and I fill each set ofretort tubes by fine or pulverized coalthrough the charginig'naoerture [a so that thus the volume e 'or pulverized coal "almost completely fills the-retorttubesand thus the partial distillation takes place under compression' due to the weight of the densechar e.
