ENTRFUGAL MACHINE V To all whom t may] concern.'

Be it linown that I, ENRIQUE A. Tononion, a citizen ot' the United States, residing at Albany, in the county of Albany and State of N ew York, have invented nen1 and useful Improvements in Centrifugal Maof which the following' is a specification.n

Reference may be had to the accompanyinga drawings, and the reference characters marlred thereon which form a part of this Specification. Similar parte in the several figures therein.

Centrifugal machines ttor liquid from solid substances. may be classified generally as of two types.

lin one type, the' separating chamber is inclosed by a Substantially solid or imper- Itorete circumferential wall against which the Solid material ie impacted by centritupal force, while the' liquid is by centrifugal force 'and the form of the chamber caused to rise and overflow from the eh amber,

lnthis type of machine a large proportion of the liquid may be 1Very quickly separated from the solid material but a thorough sep-- solid material cannot be accomplished. f

In'the other type of machine theseparating chamber in inclosed by a perliofate circumferential wallv against which the solid material, is 'impacted by' centrifugal torce,`

while the liquid passes by centrifugal force outwardly through the perforations ot said wall. I

lin this type otmachine the periorutions up upon the inner eide ot the inclosing wall olf a layer of solid materialen that .the elimination of the liquid is 2@greatly `retarded in passin through said layer o'f a though eventually the the solid material than with the type of inuchine tiret above described.

The principal object of the j recent iirrenm centrifugal advantages of the ot centrifugal machine above ilemachine the substantial two types scribed.

Other objects will appear in connection with the following description.

Application nlcdt November 3ft, 1920. Serial No. 426,520 A Fig. 2 is a similar section taken on a plane i 'at right angles to the plane of the section of Fig. l, showing the' imperforate circumferential wall moveddown below the plane of the separating chamber.

Fig, 3 is a View similar to Fig. 2, showing both the peritorate` circumferential Wall and the impertorate circumferential Wall moved down below the plane of the Separating Fig. et is a cross section taken on the broken llne i- 4 in Fig. l.

Relirrinp,r to the drawings in which the invention is shown in preferred form, the main rotatinguiarts of the machine are carricdby a central vertical shaft, l, supported at ite lower end in any suitable 'lorm of stepbearing', 2, which shaft has suitable driving connections as a pulley, 3, whereby power may be transmitted to drive the shaft at a high speed. The step-bearing, 2, is located :in a base portion, Ll, of the casingr of the machine.'

Above the pulley, 3, the shaft, l, is further rotatively supported by a sleeve-bearing, 5, which bearing is carried by the casing of the machine through thefmedium of a plurality of bracee,6, in the ilorm of a spider.

Upon the upper end of the shaft, l, is iixedly mounted a hub, 7, upon which is iiiiedly mounted the bottom, 8, of the separat` inn1 chamber ofthe machine. 1

The upper open end oi? the chamber is surI` rounded by a circular lip, 9, supported from the bottom, El, by means 4oi upright rigs, 10.

Surrounding arating;P chamber ia an apron, l1, over which liquid forced upwardly out of the separating chamber over the lip, 9, overflows into a gutter, l2, the legutter and apron, 11, being of the casing.- The liquid escapes from the gutter, 12, through an outlet, 1,3. f

The Separating' chamber is' circumferential walls, 14 and 15, the inner Wall, lll, being a pertorate wall while the outer wall, 15, is imperforate. These oircumferential walls are separately movably mounted upon and carried by the hub, 'it the inner wall, lll, by means of two pieton rode, 113, and the outer wall, l5, by meann ci tuoi onrode., l?.

,18, Vand'vduct, 23, through suitable laterals, 25, with the lower. ends fof said, cylinders respectively; and I also provide the shaft, 1, with two other longitudinal ducts, 26 and 27, communicating', .the duct, 26,l through laterals, 28, with the upper ends of the respectiv'e cylinders, 20, and the duct, 27,

. through suitable'laterals, 29, with the lower i lower end of duct, 27,2 opens laterally into a endsofsaid cylinders, respectively.

The lower Aend of the duct,l22, opens lat-l erally into an'angular'oilchamber, 30,v and lower` end of' duct, 23, opens into a similar annular 'oil c hamber, 31, these oil cham# `bers being formed 'within'the' sleeye-bear-- in, 5. i n. s 'Y he lower end of duct, 26, opens laterally finto an 'annular oilv chamber,'32,l and the similar. oil chamber, A33,said oil, chambers spectively with the oil-chambers, 30, 3 1, 32.

infp.; 1 f. 1pes,'3^4, 35, 36 and 37, communicate reand'33,'. `which pipes communicate'with a supply, not shown,of liq'uid, preferably oil, under pressure, and which pipes arecontrolledlby suitable valves or other ci'introllinlgvmechanism-I not-shown. 'j f A- t willbe seen that by. properly cont-,rol- I lingorregulating the supply yof cil under pressure to the respective 'oil chambers', 3l). .31, 32and 33, the inner and outer circumferential Walls, 14 and 15, of the separating chamber` may be raised and lowered to and from a position in which they inclose the, chamber.

Mixed liquid and solid matter to be separated is supplied to the separating chamber by means of a supply-pipe, 38, controlled by a valve, 39.

The operation of the apparatus is as follows:

Oil under pressure being supplied to the` oil chambers-mand 33. causes both sets of pistons 19 and 21, to lie/forced tothe upper ends of their respective lcylinders in the hub, 7', and thereby causes both circumferential walls, 14 and 15. to be raised and be maintained raised to a vposition circumferentially inclosing the separating chamber.

AThe shaft, 1, being rapidly rotated, a supply of mixed liquid and solid 'matter is fed into the separatingchamber through the pipe, 3S, and is immediately acted upon by centrifugal force which throws thc. solid .matter outwardly against the inner perforate wall, 11, while the liquid mattei' tends to rise within the separating chamber as it cannotl escape through themperforate circumferential wall,` 15.

AThe water is thus `caused by `the centri iugal force. -to pass upwardly overthc'lip, 5).

and apron. 11, into the gutter. l2. from which it escapes through the outlet, 121.

vlVhen the capacity of the separating chamber las` been reached the supply through the pipe, 3S,.is shut off: and when .as muclifof the liquid as possible has been expelled through the-open upper end of the chamber, tlieolrter circumfercntial wall.

15,. is forced downward to the position shown in Fig. 2, by applying the oil pressure throughkithe oil clnimbcr` 2h). and withdrawing it` from the oil chamber. 3l. thus applying vthe oil pressure to the upper ends of the cylinders, 20, and forcing the pistons. 21, downward. thereby withdrawing the, imperforatc circumferential wall, 15, below the plane ot the separating chamber.

l'lhe operation of the machine is thereafter continued causing the remaining water to be `expelled by centrifugal 4force out through the mass of,A solid material previously .impacted against the inner side of the perforate' circumferential wall, 14.-.

When the moisture has been thus extract ,ed to thedesired degree the circumferential wall, 14, is forced downward by applying thc'oil'inessure to the oil chamber, $12, and

-witlnlrawing it from the oil chamber, 33,

thereby withdrawing'said perforate wall below the plane or' the separating chamber to theposition shown in Fig 3.

As thc'solid matter which was impacted againstthe perfor-ate wall, 14, ,isthus freed from the. support ol" said wall it is thrown outwardly into the space, 10, betweenthe inner and outer Walls of the casing and falls into a trough, 41, at the lower end of said space from which it escapes through a bottoni opening, 4Q, in said tiough, and an outlet-pipe, 43, into which it is guided by a chute, 44, and from which it is delivered upon a conveyer, 45, or other receptacle.

The chute, 44, can be moved by means ot a link connection, 46, with a piston, 47,.'reciprocatory in a cylinder, 48, tothe opposite ends of which cylinder oil or other fiuid un der pressure is supplied through pipes, 49, to move the piston in the desired direction.

Beneath the opening', 42,. a Well, 50, is formed in the casing from the bottoni of which leads an outletpipe, 51, tor the escape of Water from the Well.

During the separating operation the chute,

i 444, is inovedout o't' the path ot' matter fall- Wall, and that l am 'then able to complete ing through the opening, 42, to permit the tree escape o't any water which may tindfits Way into the trough, 4l.

After the Water is extracted and it is desired to deliver'tlie solid material from the separating' chamber,`the chute is moved to a position extending obliquely beneath the opening, 42, to 'receive thesolid material and direct it into the pipe, 43.

The solid material which falls into the trough, is carried around the trough to the opening, 42, by means oit `paddles or sweeps, 52, carried by a h`ub,.53, in iixed relation to a Worin-Wheel, 54, in engagement with a Worm, 55, which may be operated in any known manner.

'It will thus be seen that during the l'irst part ot the separating operation I am able to extract a large proportion of the liquid with the same facility as with a separating machine having an impertorate circumferential the separating operation to the same degree as with a machine having a perror-ate cir- 4 lcuniferential Wall.

I am thus able to greatly expedite the sepa ation ot' liquid from solid matter to a high degree because the operation can be com pleted in a` single machine much more quickly than the same degree oit separation `could be accomplished with the perforateizylinder machines liereto'tore used, and Without the time and expense required to trans- ;ter wet stoclrfrorn an iinpertorate-cylinder machine tov a perloiatecylinder machine to complete the separation to the same high degree. i y

' The machine can be continuously operated u as successive supplies oit mixed liquid and Btl solid. mattei' are delivered to the separating chamber, separated and delivered trom lthe separating chamber.

The iinperforate Wall, '15, forms in eliect a blind'for the openings in the perforate wall, `14'; and tor certain purposes of the invent'ion, blind-mechanism of any known forni may be employed 'for temporarily clos ing the openings vthrough the perforate Wall, 14.

rlhe Walls, 14 and 15, are preferably of complete circular form in horizontal section, but the extent of the perlfoi'ate .and imperorate areas is immaterial for, certain pur poses of the invention provided the perforations can be temporarily closed or blinded to permit the extraction ot' the liquid by voi tical displacement when desired. y

A further feature of inyinvention consists in the method otselfiaration above disclosed whereby a Wall ot solid material is centrifugally builtfup While escape oit' the liquid through the wall is preventedand some liquid is'centrifugally separated and removed by vertical displacement, and completing .the .separation by centrifugally expelling ad said built-up Wallet eriv tially preventthe passage of liquid throughl n the neighboring peritorate Wall.

4For certain purposes oit the invention itis' immaterial. which ot the pertorate and iinperliorate. Walls is the innerl Wall and Which the outer wall or the separating chamber; but for convenience of construction prefer to have the perforate Wall `located Within the impertorate wall whereby both walls can be moved into and out of position. by like moven'ients,l thus leaving one end of the separating chamber practically unimpeded by -Wall-operatiIig-mechanism, and permitting treeescape for the Water separated by verm tical displacement. l

What I claim as nevi and desire to secure' by Letters Patent is l. A centrifugal machine having a rota-l tory container with two circumferential Walls, one perfo 'ate and the other inqcerion rate, and means tor moving; the in'iperitorate Wall out qt the planeI oit rotation oit the chamber of the container.

2. A centrifugal machine having a rotatory container' vvitli tvvo circumferential Walls, one perforate and the other imperia rate, and means for moving' each oli said Walls out ol. the plane oit rotation oir thel chamber of' the container.'

`8. ln a centrifugal machine, and in coin-A A a rotatory shaft carryingsaid container with' said 'Walls separately into and out of position to inclose the chamber 'of the container;

its two Walls and said'piston-mechanism; and ducts within said shaft for supplying fluid under pressure to said piston-mechanism.

4.- In a centrifugal machine and in combination, a rotatory container With two circumferential Walls one perforate and the other imperforate; means' for moving each Iof said Walls out of the plane of rotation. of

the Chamber of the container; means for delivering Afrom the machine liquid centrif- V pgally separated by vertical 'displacement v 1 om the container; and means for delivering from the machine liquid centrifugally the chamber of the container; means for delivering from the machine liquid centrifugally separated by vertical displacement from the container; a receptacle surrounding the container provided with a liquid outlet and` an. outlet for solid material; and Valve-mechanism whereby7 said outlets can be alternately opened.

`6. That improvement' in the art of separating liquid from solid substances which consists in -centrifugally building up a wall of solid material while preventing the passage of liquid therethrough and centrifugally separating and removing liquid by vertical displacement, ,and completing the separation by centrifugally expelling additional liquid through said built-up wall of solid material.

7. That'improvementin the art ot' separating liquid from solid substances which consists in centrifugally impacting a' body of solid material upon a perforate wall while escape or' liquid through the wall is prevented and liquid is centrifugally separated and removed by vertical displacement, and cornpleting the separation by eentrifugally eX- pelling additional liquid through the impacted body of solid material and the perforate Wal In testimony whereof, I have hereunto set my hand this 18th day of November, 1920.
