To all whom .it 'may' concern:

Be it known that we, JOSEPH CHANCELE .CHAIX andELm DUH, citizens of the isiana, have invented a new andv useful Centrifugal Attachment for Sugar-Driers, of' which the following is a specification.

This invention relates to a centrifugal attachment for sugar driers.

Theobject of the invention is, in a ready, simple and practical manner, to` eliminate the hand work which is at present used in sugar houses and refineries, to cut 4the dry sugar from the inner sieve and force the same out of the centrifugal, whereby labor and time will be saved and the work of drying the sugar greatly expedited.

A further object isto provide an attachment of this character which shall be4 of such construction that its attachment to a centrifugal already in use will not require .which when not in use may readily be re moved lto a point within convenient reach when again needed.

, With the above and other objects in view,

'as will 'appear as the nature of the inven ltion is better understood, the same conslsts in the novel construction and combination of arts ofa centrifugal attachment for [.sug r driers, as will hereinafter be fully In thevaccompanying part o'f this described and claimed.

`held against dropping Referring to ,the drawings, 1

the outer shell of a `centrifugal of any preferred type, 2 the sieve, ,3 thel discharge chutes, which are disposed .beneath openings 4 in the imperforate portion 5 at the, enter of the sieve, 6 a polygonal spindle rigid with the portion 5, and 7 a sleeve movable onthe spindle and provided at its lower endgwith a base 8 arranged normally to close the openings 4, and at its upper end .with a ulley 9 that is designed to be driven, bya Nelt,

not shown, actuated from any suitable source of power. y A As usual, the shell is provided withan ,in-

turned flange 10, upon which is boltedthe attachment which consists, in part,` l.of a

bracket 11 that is secured to the.` flange by bolts 12 so as to 'be removablewhen, ydesired. Bolted to the bracket are twovertically disposed tubular bars `13 whichlpass loosely through orifices in a head 14: and have their upper ends connected by a `plate 15 carrying three sheaves 16, 17 and 18:,-the first and .last named sheaves being disposed over the open upper' ends of bars l13.L These sheaves are engaged by a rope or chain 19,

the' two ends of which pass. around the shcave 17 in oppositedirections and around the sheaves 16 and 18 and have attached to their free ends counterweights 20..'f`The lower end of the rope is secured to an eye 2l arranged on the upper end of the heed 145 which latter slides on the bars.

Carried by the head and rigid therewith, is the upper-end of a shaft 22, the lower end of which terminates a short distance above the Hoor of the screen. shaft are two collars 23 and 24 eahof which is provided with a tubular extension 25 and 26 respectively, and these extensions are engaged loosely by a shaft 27 that is stepped -into the extension 26 and is thus Hinged to the'shaft 27 is a curved metallic plate 28, havingse- Secured upon rthev cured to its outer edge a wooden bar 29 that vis designed to scrape the sugarfromthe screen, wood being employed to prevent cutf. ting of the latter: The plate fisprovide'dl with a series of hinge butts 30that 1nter lock with similar butts 31 carriedbyone edge of a curved plate 32, the two series f )fbut-ts being engaged by the shaft 27. yIn operation l the member 28' constitutes aA cutter, yand-the member 32a sweep, and by these terms these parts will `hereafter be referred to. In order lever has connected with it one end of a link arm 37, rigidly secured to the upper end of 36, the other end of which connects with an the shaft 27.. It will be seen by this arrangemovement of the sweep, a stop ment that when the lever 34 is moved toward the head the cutterwill be brought into contact with the sugar, a reverse movement holding it out of contactwith the sugar. Normally the sweep lies close to the cutter,

being held in that position `by-means of a coiled spring 38, the ends of which are secured in eyes 39 and 40 carried respectively by the cutter and the sweep. The lower end of both of these last named elements has a brush 41 and 42 connected with it inorder t0 sweep the bottom ofthe centrifugal free from the sugar. To limit the outward 41 is provided, which is rigid 'with the shaft 22, as clearly shown in Fig. 4. l

-It will be observed b' reference to Fig. 1, that the attachment hasno other support than the flange 10 of thel shell, andfin order .to prevent the latter from sagging from the weight of the attachment a brace .43 is employed, one end of which is bolted to the side ofthe shell, and to the otherend to the bar 13, and 'this arrangement will 'positively hold the attachment in vertical, and thus operative position and insure proper contact between the scraper and the screen.

In operation when a fresh chargeof massecuite is to be supplied to the screen, the head 14 is raised, thereby lifting the cutter and sweep out of the screen, and the sleeve is lowered to cause its base to close the openings 4, and the driving belt, (not shown) is positioned on the pulley 9, it being understood that the belt is removed each time the sleeve is raised. The centrifugal is now started and continues to run until all of the liquid is expelled and the dried sugar has accumulated on the walls and bottom ofthe screen.- The sleeve "7 is now raised to the and the shafts toxvhich they are attached, so'

that no means need be employed for holding the attachment out'of the screen. The een trifugal is again started and the operator swings the lever 34 to one side thereby bring-- ing the cut-ter into engagement with the I' walls of the screen and as soon as the sugar ceptacle. Vhen the operation is completed the attachment.. is again raised, the sleeve lowered and the operation of drying again repeated.

l. An attachment for centrifugal sugar driers comprising a'stationary cutter having a scraper arranged at one edge, a -sweep having-pivotal relation to the cutter, andv means for holding the sweep normally in folded" position relative tothe cutter.

i v 2.

5. An attachment for vcentrifugal sugar driers, comprising a bracket, tubular bars secured at their lower ends to the bracket, a plate connecting'the upper ends of the bars, pulleys` carriedy by the plate, -ropes passing around the pulleys and carrying weights at their free ends disposed-within the bars, a head slidable on the bars ,and to which the lower end of the rope is secured, a shaft rigid with and depending from the head, a second shaft supported by the first Shaft, axed cutter and a; hinged sweep caras our own, we have hereto axed our sigriedby the second shaft, the sweep .being natures in the presence of two witnesses.
