cia-Annes W, GnANNIs, or GOWANDA'NEW 4ironic-v Spec'iiieation forming part of Lett-ers Patent No. 36,403, dated September-9,1862.

1'0 allrwhom/ it may con/cern, Be it Iknown that I, CHARLEsW. GRANNIs, of Gowanda, in the county of Erie and State of New York, have inventedA a new-and improved condenser for use inthe distillation (if-petroleum or rock oil, coal-oils,l and otherl distillation; and I do hereby declare that the v, 'follovving isa full and exact description thereof, reference beingfhad to the accompanying. drawings-making a partof this specification,

which--I l Figure I is -a longitudinal vertical section of my improved condenser in combination with a caldi-en Fig. lLis a transverse vertical sec-A tion of the same. l j v The nature of my invention4 relates to the construction'and .useof a condenser in the 4form oflla roof oreover to sit'on and over a ealdrontor kettle) containing voil for dstillatien; which condenser 1 is" provided with van internal iiange ortrough for conducting off the condensed vapors to an externaleonductor; also, inproviding an apparatus for throwing jets or 'streams ot' cold water upon the-outer surfaceof the condenser',

Letters of..like name and kind refer to like lparts'in eaeho` the figures. A

A'. represents a large cast-iron caldron or" kettle, or still, eight feet in length, three feet in depth, and seven feet in breadth, (more or -less,) having a horizontal .flange/or rim, as shown atc, for supporting the condenser, and'.

a vertical flange or rinna", for the purpose of a trough to collect yand conduet'nffA the waterl .Whichis thrown-upon the outside of the condenser. This ealdron is suitably setin an arch or urnace of briekavork, as shown at A.

fB represents the condenser. It is made of metalyin the form of a roof or cover to sit-upon 'and-over the caldron. `It has two sloping sides.

The essential' feature of making an internal trough to catch and conduct the condensed vapors and-of giving sufficient inclination to the sidesof the condenserto .insure the' condensed vapor to run down the internal surfacetothetrough must in all cases'be observed,

whatever 'may be thc configuration ofthe con'- denser or cover. It has a ii'ange at `its base, as shown at b', which sits on theh'orizontal iiange or rim of the ealdron` and inside of the vertical rim. It ,is-bolted or otherwise securely and tightly fastened to the horizontal flange of the ealdron, making a steam-tight and Water-tight joint thereon. A' Upon the inside, and near the-bottom, is formed a trough,

as .shownlat e, forI catching and conducting away the vapors which are condensed upon the.

broad internal surface of the condenser. This trough connects with the external spout, D. At E is. representeda Water-pipe placed over the.condenser and .lengthwise thereof, having.- lsmall apertu-resnel for spurting coldlWater upon they outer surface of .the condenserr,

Fis ay supply-pipev connecting with a res`er.

voir of eoldj'water rand supplying the pipe Et with sufficient water for coolingthe condenser..

,Asa modification l have eontemplatedcarl ryingthe vertical rim of the vcaldron upsuiiciently high to forma large water-tank, so that the'outside of the condenser Will. be immersed in cold Water, vin which case the pipes E and. F 'would .be dispensed with.'-

(lv represents al, wastewaterp1-peter lcarni/-4 'ing off the'water from the trough after ithas fallen .upon the condenser. The spout or pipe.

Dl eonducts'the distilled oilsy from the` condenser. tothe worin or cooler. A-trough, H,-y

is placed around the pipe D, -whieh contains' cold j w'aterfor cooling the pipe.

-I represents a'spout for carrying 0H the sediment which accumulates in the bottom of the caldron. y l

J represents a man-hole, and which may also.

be used for admitting oil into the-ealdron. 1

Operationz' The e'aldron is filled nearly full; of petroleum vor rock oi-l (or other oil, as-the. ease mayl'beLanda hotv fire made inj-the fufrnace under the caldron. When the tempera; turefis suici'ently high, the. vapors arising froi i1the boiling-oil will impinge upon the in# 'ternal inclined sidesof the condenser and'become condensed: thereon and rup down into the trough c, -from whence they areconducted through the-pipe'vD'to awor'mor-cooler. .'Ihe

condenser being placed over and upon the caldron and in,suelpeloseproximity to theboilf ing oil thatl it aetsgvith great eiciency, all the cold for effective and'rapid Work.-

I claimr as my inventiono i o `A condenser which combines the following features, `toA wit: rst, sloping. sides; second, an internal trou'ghV to' catch and conduct the condensed vapors toen. external conductor;-v

` third, an external spout oreondnctor passing o 4through-.or ina trou-gh'o vcold waterfto. con-v duct the condensed vapors Ato the Worm or cooler;fourtl,`jetsoi Water or a' body of cold l' `water upon its ontside', ncombinati'on witl'i afealdron or. still'haying a broadopen'top,

'upon which the condenser isY tted, forming a Y coverA thereto, so that the vapors arisingfroni the entire surface of ,the oil in' the still may passdirectly to the condenser, substantiallyas described. v 4 CHAS. GRANNIS.I i `Witnesses: .l
