3e it knowuthut I, FlmNoLs l. Hoen, sole assignee ot' the patentgranted to J'osnr'ir Hmm ou the 3d day of October, 1844, and sole :ulministrator of the aforesaid .losnrn HURD, now deceased, do hereby make known the following as a full and exaet description and speeiiieation of the invention o1' .lossen HUND aforesaid.

The proeessol' poitingsugar or freeing it from sirups ortreaele, (molasses,) as praetieed in the XVest Indies and other countries, eonsi'sis in allowing it io stand for a considerable period ottime in hogsheads, easks, or eisierns havingr holes bored through their bottoms. The force oi.' gravity causes the sirup or treaele to grmlually'deseend through the sugar and ese-ape through the holes in the bottom ofthe hogsheads. in order bythe above operation to expel the sirup or liquid suiliciently to render the sugar lit i'or the market, much time is necessarily consumed. Besides, large euring-houses,77 as they are termed, adapted for the purpose, must beerected and maintained.

My improvement` consists in eil'eeting the separation ol the molasses by a maehine ol' a peculiar construction,whieh accomplishes the .'ame through the ageney ol.' eentril'ugal force.

Figure l represents a top view ot' the said ma'ehine. Fig. 2 is a central and vertical seetiou thereof'. It consists of a cylinder or other proper slraped eisteru, A, surrounding and having within it another Cylinder or other suitably shaped vessel, l, which is attached to or has a vertical shaft, (J, passing through its axis or central part, as seen iu Fig. 2, and so arranged in bearings and in other respects as to be capable of being revolvedl ou itsaxis, and thereby impart a eorresponding motion to the vessel B.

Au external view ot' the vessel B as it appears when removed fromthevesselAis given in Fig. 3. As a eonvenient and simple mode it ol' a eireular and solid bottom, a, (ofl wood or other propermaterial,) having raised upon it a cylindrical' wire framework formed oi' strong Wire 'or strips of metal wound iu a helix and secured i 1= such a form by any suitablenuml'ier ot' Vert 'al wires or ro'ds erst-rips, C C, de, inserted and confined in the plaie or bottom u, and a metallie ring or rim7 l), theI latter oi'w'hieh is' -conneeted to the eentral shall, (l, by arms lfl E E lil. rlhe I'rznueuork surrounds and is intended to give support lo a hollow eylinder, F, of woven wire, whose inner suriaeeislined with flannel a', or other suitable material, the object ol' the whole being to sul'l'er the eseape ol.' the sirups, molasses, or liquid matters through the sides ol' the vessel, l, and at the same time to retain the sugar n'ithiu it whenever the vessel is put in rapid revolution. The said vessel maybe revolved within. the eisteru A by means or' a pulley,l ll, iixed on lhe top ol' the shal't, around whieh (pulley) a band i'rom the driving-power may extenfland give motion to it. y

The sugar containing the molasses is to he thrown into the interior ot' the vessel. LIS, and when the said vessel. is put `in rapid revolution the centrifugal torce generated in the molasses or sirup or liquid matter will expel it,

i'rom the mass of' sugar and' drive it through the sides ot' the ehambe' l iu'to theeistern surrounding the said chamber, from which it may be removed through an. opening or i'aueet at l. A l

Snel). a ,machine is so'el'l'eetual iu discharging molasses, sii-ups, and other liquid matters from sugar that but a short timeis required to ei'i'eet by it what requires a a ery longeperiod by the old proeess hereinabove detailed.

Although I have described such a machine as my own praei ical experieneehas proved to be ol' the simplest andy most convenient kind for the purpose for which I haveused it, yet others, varied inform and mode of lconstruetion, .maybe madeuto operate in asimilar man` ner, so as to expel thesirnp, molasses, or other liquid from the sugar containing the same.

The machine which is the subjectief this i specification effects its object-viz., that of lexpellngliquid f rom the mass o,`,-sugar-through the agency olee'utrii'ugal force alone. I also use the said machine for washing sugar, andthis I eli'eet by gradually pouring or discharging water or other eleansingfliquid upon or near the center or other suitable parts of the mass oi' sugar contained in the eyliudrie ves- Asel l while the said vessel is in rapid revoluy tion. The water or cleansingdiquid will thus be vdriven through the mass and, sides of the vessel by the action of centrifugal force. After the su gar has been freed from molasses or other impurities 'in this machine, either by the action of centrifugal force alone 0r by washing, it will be found, as it were, plastered upon the inner periphery ofthe revolving cylinder` It is then to be removed therefrom by proper tools and lifted out ofrthe open top of the vessel.

The Vessel will then be ready for the succeeding charge.

What is .claimed as thcinvention of. J esErI-I HURD, deceased, is-

l. The process of separating sugar from any liquid inattere with which it may be mixed by filling the mixed inassinto a vessel construct- 'i ed substantiallyas described, and there acting upon the same by .centrifugal force, substanj iially in the manner specified.

2. The washing ofimpurities out of the sugar by admitting a liquidinto a vessoLsubs't-an tiall-y such as described, in which sugar is being exposed to the action of cent1-ith gal force,

ras specified.

3j The process herein described of 'obtain ing a mass of sugar freed from liquid impuritiesbby filling the mixed mass into the top of a vessel constructed substantially as described,

and having a closedbottoin, and there exposing the mass to the action of centrifugal force,

and then withdrawing the sgur ont of the upper end of said vessel when separated, the whole as, specified.

4. The processoibtaining a mass ofwashed sugar by charging edgar into the top of a vessel constructed, as epeciiied,\vitl1a closed bottom, and then exposing such sugar to the action of centrifugal force, and while so exposed admitting currents of liquid to wash the sugar, and, finally, withdray'ing the washed sugar out of the top or upper end of the vessel,

the whole process being substantially such as speciiied, and being` claimed byme as the in vention of said J OsEPH HURD, deceased.

In testimony whereof Ifhave hereunto sub- 'scribed my naine, in the city of New York, on

this 28th day ot' September, A. D. 1S5S.
