IMPROVED VACUUM-PAN SUGAR-BOILIN'G APPARTUS.

T0 ALL WHOM MAYV CONCERN:

Be it known that I, CHARLES HARRIMAN, ofv the city, county, and State of New York, have invented a certain ne\ v and useful improvement in Vacuum-,Pan SugariBojling'Apparatus, of which the following is a full,l

clear, and exact description, reiference being had to the accompanying drawing, which forms part of this speciiication,and which represents a sectional elevation ci' a vacuum-pan sugar-boiling apparatus constructed according to this improvement. v

The nature-of my "invention consists in the application fto thereceiving-charnber for the aqueous vapor from- 'the vacuum-pan, of a pipe-or tubel containing liquid extending to a depth exceedingthe height to which a column of water would be raised by atmospheric pressure as opposed to `the vacuum of the pan, and constiiuting what may be termed a Torriellian tube for the purpose 4ofA catching snccharine matter carried up by the vapor without destroying.orinterfering with the vaeuum.- l

Referring to the accompanying drawing, lA is the ordinary or any other suitable vacuum-pan in which the sugar to be treated is placed, andwhich may be heated in the usual manner. ,VVB isthe pipe which serves to establish communication between the vacuum-pan and air-pump, and also to" pass ojithe aqueous vapor into the ordinary vertical receiver or chamber C, from whence it'passes and is drawn by the pump into a condenser, D, receiving a spray supply of waterat its top, and connecting at its bottom with a p'ump, E, that in addition to effecting the vacuum in vthe .pan A expels the condensed vapor into -the seweror Waste.V This, so far, is an prdinary'construction o'r combination of parts. vAs it is well known, however, that in spite of all preventives to the contrary much saccharine matter or sugar is by such an apparatus passed over with the vapor, and in the condensation whiohtakes place expelledby the pump into the s'ener onu-aste, I apply, in remedy of this defect, an attachment which shall not merely-catch or concentrate the saccharine matter escaping`- from the vacuum-pan but give the Overseer, or thosehavingcharge of the apparatus,'an opportunity of detecting such overilow from-thevacuum-pan, and correcting, so far as practicable,y the escape of sugarv therefrom. This is or may be .accomplished by attaching to the bottom of the receiver C a Torricellian tube. or pipe, of say somewhat over thirty-three feetin height, and supplied with water or liquid by any suitable means from aV vessel, F, below, which may, if desired,r stand in an outer vessel or tub. These vessels may be arranged on a lower story of the building, while the vacuum-pan is situated on an upper one. From this description it will :be apparent that saecharine matter carriedup byltheaqueous vapor into the receiver C will, by its. gravity, be restrained from passing over into the condenser-'"D, and, falling, be received bythe pipe E, and settle in the tub or vessel F, and from thence it may be passedover into the surrounding tub or vessel. Not only, however, does such an attachment serve to intercept or collect saccharine matter which otherwise would be passed oil? to the waste with `the condensed vapor, but' it also affords a ready means for thejoverseer, lor those Ahaving charge of the apparatus, to detect, by taste Lof the liquid in the vesselV F, or its outer tub, the extent of s'ngar escape from t the vacuum-pan, and in case of the same being excessive, and arising from defect in the, apparatus, to call attention'to the feed-and give directions for removal of the cause. vBy this means may much sugar besaved that is now wasted or passed oil' into thel sewer, i

-What I here claim as'n'x'yinvention, and desire to secure by'Letters Patent, vis-l The combination with an apparatus, substantially of the character specifici-of a. Torricellian pipo or tubo, E, connecting the receiver (l with a vessel or vesselsV below, essentially as and for the purpose herein set forth.
