CENTRlFuAL EXIRAHCIOR For SUGAR-CANE lulcr AND OTHER Lloulus.

- SPECIFICATION forming parpf Letters Patent No. 239,222, dated March 22', 1881.

Application tiled .lanuary 24 1R81. (No model.)

To'all whom it 'mcg/'concerm Be it, known that I, HUGH BURGESS, a subject of the Queen of Great Britain and lreland, residing in Royers Ford, Montgomery county,Pennsylvania, have invented `certa-in Improvements in Centrifugal Extractors for Sugar-Cane Juice and other Liquids, of which the following is a specification.

. The object of my invention is toconstructa lo machine for rapidly and thoroughly extracting juices from sugar-cane or liquids from other substances by the combined action of centrifugal force and direct pressure.

In the accompanying drawings, Figure 1,

I 5 Sheet 1, is a vertical section of my improved centrifugal extractor;l Fig. 2, Sheet 2, a plan view Fig. 3, a sectional plan on the line l 2,

` Fig. l, and Fig. et a sectional plan on the line 2o `Aidis a vertical shaft, having its upper bearing ina boX secured to a suitable frame, of which the beam B forms a partand its lower bearing in a step, b, secured to a suitable foundatiomd. This shaft is tubular, and its 2 5 upper end has a stuffing-box for admitting the end of a pipe, D, which is furnished with a suitable stop-valve. I

The screen consists, in the present instance of substantial ribs f, preferably of T- iron,

3o these ribs being properly bound together and arranged at such a distance apart that there The upper end of the screen, comprising the ribs f, is properly secured to a ring, h, lagainst which bear horizontal disks or rollers i, the

spindles of which have their bearin gs in plates F secured to the frame-work of the machine, the rollers (of which there may be three or more) serving to maintain the upper end of 4o the screen as it revolves concentric with the shaft A. The lower end of the screen rests in and isproperly secured to the ring j of a casting, G, the ring being connected to the hub K of the casting by a number of lugs, m,

for a purpose explained hereinafter.4 This screen-supporting casting is adapted to and can turn independently of the shaft A, and is driven by a wheel which gears into the wheel L, the latter being secured to the hub of the 5o said casting. "Another wheel, M, is secured to the shaft A below the wheel L, and bel tween the two wheels there -is a loose collar, u, on the shaft A. The screen is contained t lvo'of whichip p', are for the discharge ofthe rex racted liquids or juices, the third outlet, l), ning` for the escape ofthe waste caneror uid has b "en extracted. f '\lrt will be seen that the scrggff T5' gradually contracted in "lrtr;tHQ-;Ithe top toa iiange, 00, below which f|'i'e"f'screen is enlarged at y, and is again gradually contracted from this point to the ring j of the casting G. The object of this peculiar shape of the screen will be rendered apparent hereinafter.

rlhe flan ge previously referred to, projects from and rotates with the screen, and it overlaps a flange, q, projecting from the interior of the casing N, so that all the liquids discharged from the screen above the flan ge :v must escape from the outlet p. `In like manner the tlange j, secured to thc lower end of the screen., overlaps a flange, q', projecting from the interior of the casing, so that all the liquids which are discharged from that portion of the screen between the two angesw andj must pass through the outletp.

That portion of the shaft A which is contained within the screen has a spira-l flange, zo, which varies in diameter as the screen varies, so that there may be as little space as possi ble between the edges of the flan ge and the screen. It is not essential to my invention, however, that this spiral iiange should be continuous, fora system of oblique blades somewhat like those of a propeller may be secured to the shaft. p

`The operation of the abovedescribed machine is as follows: In treating sugarcane, for instance, for the extraction of the saccharine juices, the cane, cut into comparatively small lengths, is fed into the top of the screen, and under the iniiuence ofthe spiraljian ge w of the revolving shaft A the cane is" fed downward until the whole space within the screen is tightly packed with the cane.` As the cane descends it must necessarily be subjectedto .a continuouslyincreasing pressure, due tothe gradual con traction of the upper portion of the screen." The cane, under this pressure, `yields its saccharine \vithin acasing, N, which has three outlets, I

bagass y or other materiahfrom which the IOO juices, which, by centrifugal force due to the tween the lugs which connect the ri 55 the juices from the cane.

io so that the cane, after passing through the contracted upper portion of the-screen, is saturated with water, and the enlargement .of the screen permits the mass of cane to expand and absorb this water, after which it is again sub- 1 5 jected to gradually-increasing pressure and the water is extracted, carrying with it thejuices which it has washed from the cane, the com, bined water and juices heilig expelled by cenfI trifugal force and passing through the outlfet The waste disintegrated cane or baga sse passes from the lower end of the scree. be-

i 'g j and through him-K of the casting G, and thenc j the outlet??- As regards the -jtl Ol T110 screen and the shaft A, it may be remaile'l that the speed of the former must be determined by the centrifugal force to dispose of the juices extracted by the pressure due to the spiral tiange. of the 3o rotating shaft; but there must always be such a difference between the speeds of the screen and that of the shaft that while the former discharges the juices by centrifugal action the latter exerts a downward pressure to extract The shaft A must be rotated in a direction determined by the direction in which the iiange is coiled round the shaft, or according to the direction in which the oblique blades are inclined, so that down- 4o ward pressure may be exerted on the material to be operated upon.

An important result is attained by the arrangement of gearing described. When the machine is in operation the strain is exerted upwardly on the shaftand downwardly on the screen, so that the down-pressure on the top of the collar n between the two wheels will be counteracted by the upward pressure of the sha-ft against the under side of the said 5o collar, and the step b will be relieved from that sion of the screen at y and the admission of water at this point may be unnecessary, the screen being made on a gradual taper throughout; but in operating on sugar-cane I prefer this expansion of the screen.

I have referred above to the cutting of cane into comparatively short lengt-hs before it is fed to the machine, but there may be a plate, s, on the beam B of the frame, as shown in Figs. l, and 2, and the stalks of cane can be held perpendicularly over the mouth of the screen", and a knife, s', on the upper edge of the flange w may strike the stalks against the said ,"plate, and thereby sever the same intol suitable lengths. The use of the peculiar screen shown and described, while preferred, is/not absolutely necessary, as screens of perforated plate or like material may be employed.

I claim as my invention-f- 1. The inode herein described of extracting" juices from sugar-cane or liquids from other substances, the said mode consisting in applying pressure to the cane or other material in arapidly-revolying screen, substantially as set forth.

2. The combination of the tapering screen and shaft A, having a spiral flange or inclined blades, with gearing, whereby the within-described dit'ferential rotation is imparted to the said screen and shaft. l 3. The combination of the shaft A,-having a spiral liange or oblique blades, the screen and the iiange w, with the outer casing, N, having an internal flange, q, and outlet p, as specified.

4. A centrifugal machine in which a tapering screen and a shaft having a spiral ange or oblique blades are combined with an outer casing, N, having an outlet or outlets for the liquid extracted and a separate outlet for the material from which the liquid has been extracted, substantially as set forth.

5. A centrifugal machine in which a tapering screen enlarged at a point between its upper and lower end is combined with a tubular shaft having a spiral flange orinclined blades and orifices through which water or other liquid can be discharged at or near the point of enlargement of the screen, as specified.

6. rIhe within-described screen, consisting of T-bars bound together, with spaces between, as set forth.

In testimony whereof'I have signed my name to this specification in the presence of two subscribing witnesses.

' Witnesses: .HUGH BURGESS.
