To all whom it` may concern :V
` Be it know-nthat weo CHARLES Louis -CORNB and Denis P. J. BURGUIERES, citizens of the f United States, residin clear, and exact description of the inven-l 1@ tion, such as will enable others skilled in the at Louisa, in the .parish of St. Mary an Stateof Louisiana,

A represents any suitable platform V or support on which theseveral settlingwtanks B, B', B2 and B3 are all pyramidal' inr shape and rectangular 1n horizontal cross-section, and the( outer tanks B and B3 have end Walls, orend' bottom plates b terminating slightly below the Atop of the side walls or .side
bottom plates b3, as shown in Fig. 2. f f
The inner bottom plates b are slightly shorter than the bottom plates b2, asshown in Fig. 2, and parallel to these bottom plates preferably in the form of metal plates, bolted to the sides b3 of the yvarious settling tanks. Secured in thesey various settling D bolted to the sides of the settlingtanks B, B and B2, as shown in Figs. 1 and 2 `In the settling tank B3 we provideinstead` of the metal. plates D, a series of removable frames E, each carrying cloth panelsy e, which frames slidein the grooves e in ,theA E', secured to the inside ofthe tank B3,.as shown in Figs. l, 2 and`7." These blocks E are secured to the .tanks kin'any convenient way, asby bolts" passing through the bolt/holes 6, see Fig-Z; At thelreceiv'- ing endl of the system we provide .an over-4 flow through F,adapted to receive the scumand Skimm'ings, which trough is preferably provided with aninclined bottom` f, exilptyfk portion f into the pipe ,G for carrying oif ther skimmings; and onlthe we provide an `adjustable plate H (see Fig..8`), adjustablyheld in of the overflow maybe-regulated within the desired limits. At the `oy'i'posite end of are mounted. y These tanks .f
' b2 we provide a series of diaphragmsC f 'Ityk tanks, and parallel withthese .diaphrag'ms Cy are a series of short, inclinedfmetal plates soL vplace by the clamp bolts It, so that-the depth system we .provide ya similar trough F to receive the clear liquid which is delivered. to the pipe G. The juice is suppliedxto the apparatus throughl the delivery main I, M which 1s connectedto the header I', which header is connectedpby thesrunall pipes to the distributing trough K, havingk the slot A.
tanks as sh own mostr clearly bo to 1ro y ros y' carrv oil the settlings, and the various pipes usedin the apparatus are controlled by suitable valvesin the ordinary way. The various tanks B to B3 are supported inany convenient way, as by means of the I-beanis lll and the braces N and N.
ln the modifications shown in Figs. 0,10 and ll the end partitions plates are similar to those al1-eruitv described with 'reference to Figs. 1 and 2, as also are the diaphragme plane metal plates C2 and D2, as shown in Fig. 1l.
In Fig. 12 the corrugated portions C3 ot the partition plates `and Da of the diaphragme are shown as V-shaped instead of lightly rounded at the bends,as shown in lig. 1l.
Now referring iirst'to Figs. 1 and 2, the operation of the devieeis as fol1ows:-The juice being supplied through the main l to the trough l( Hows gently through the slot It" near the bottom l; of said trough, into the First tank B, and gradually rises in the system until it reaches the level indicated by the dotted line L-L in Fig. 2.A As soon as all the tanks are lled to this level the continuous operation of the device begins. The
i `partition C, and the mud tends to settle on the end plate Z) and gradually drops to the bottom of the first tank. The liquid flows through the system in the direction of the arrows, and as the liquid passes between the various partition plates D, the mud will tend to settle' end accumulate on these plates and to drop oil, falling toward the bottom of the tank.
tank B3; but it will carry along,r with it 0er-,
tain'lighter particles, such as scale, small particles of bagasse, or 'the like, and these a separated out by the clot-h or burlan panels c, which do not screen the liquid but and (lll.
W'o have found in practice that where a merely the cloth catches the solid particles Most of the ruud and such other heavier solid pa rticlcs as still remainin `the system will drop down to the bottom othe tank B, and accumulating there may be drained oil as required. The (inal result will be that the liquid, practica-llyiclear, will flow `into the delivery troug u F', and be carried olf by the delivery pipe 'G'.
While the plates D may be permanently` attached in the settling tanks`,they may bewashed at such times as the apparatus is washed. The frames E carrying the cloth panels e should he removed from time tt time and cleaned, fresh frames bein insert ed while the soiled ones are being e eaused.
In the modification shown in Fig. 9, a still better precipitation of mud is secured, owing to the corrugated forms of the diaphragme D and D and of the separating plates C These diaphra rms form tortuous passages. which form. a. plurality of laterally connectingr troughs, and the mud tends to settle on the sides and finds its Way tothe bottom of each trough, and, flowing down the trough, falls in a thin stream to the bot toni of the corresponding tank. There will be a series of such pencil-like streams of mud between which the cleansed liquid is free to move without being contaminated by' the mud.
ln operating this system7 we depend'upon the fact that solids will separate from liq nids more rapidlyT on inclined surfaces than in the bottom of a settling tank having verti cal walls, and by the. inclined arrangement of defleetors D and E, and the inclined bots Vtoms of the tanks, we secure a much more rapid deposit of the heavier particles of solid matter from the liquid than it tanks with vertical sides were used. Moreover, by changing the direction of the current ol liquid on each side of the diaphragnns C. as shown` the tendency of the liquid to deposit the heavier solids held in suspension is fur ther increased.
It will he seen that inl this system there is a very gentle flowing oi liquid romoneend of the apparatus to the other, and the velocity of which flow is practically uniform in all of the tanks, and at all portions of each tank. thus differing from any of the systems new in use; Where the juice is pumped through'a large pipe to one tank, thus agitating the entire contents of said tank, and then is pumped through another pipe into thc sceond tank, wheres similar agitation takes place.. with the result that 'the mud is stirred up with thejuice, and the floceulates are broken up, `instead ot" being allowed to slowly settle from the juice.
By this system practically all of the mud and heavier particles:arctaken oil in the earlier oi the process oit scttlinaf:`
`wherc the scumy may be fi iaeosea cloth and taken off near the end of the operation, the' result 'being that an extremely clear liquid product is secured.
Since it may be desirable qualities of juiceto raise or 'lower the level. of the partition between the first settling tank li and the trough F li which may be raised or louered as desired.
:Practically all of the scum ,will rise between the first plate C and theendib .of the first tank ligand may be 'conveniently removed through the trou h Fand pipe G, tered out, and the juice returned to the system in the usual .way. While we have shown-four such tanks B, B, B2 and B? it Will be obviousl that the number `of these may be increased at will, and'that more than one of said tanks may be provided with removable screens or partitions, either of cloth or metal, as desired.
