Specification of Letters Patent. Patented June 21, 1910, Application filed September 14, 1908. Serial No. 452,964.

solids from liquids; and my 'primary object is to Wovide a centrifugal machine which will 'operate etfectivelyand economically to separate s'olid mattei' in la finely divided state from water in which thevsolid matter is practically suspended.

It may be preliminarily stated that according to a process for preparing peat invented by inc, the peat is reduced to a practical state of iiuidity and uniform quality and consistency, and is then subjected to centrifugal action to separate the peat from L the water of suspenslon. The centrifugal machine herein described may be very usefully employed for such a purpose.

The accompanying drawings illustrate the preferred embodiment ot' my invention.

Inthe drawings- Figure l represents a -brokclfrvertical sectional view of a cent-rit ugal separator constructed in `accordance with my invention; Figc 2, Van inner-orlpwer tace View of the casing-top empioyed; Fig. 3, a plan view showing the interior of the machine, the casing-top and the removable .flange o the lower or main'casing-section being` removed; Fig. il, a bottom view of the lower or main icasi11g-section; Fig. 5, a plan view of the hub which supports and is removably connected with the lower casing- .,apction; Fig.. G, a broken elevational view of' V40 saiddiub and thc'lower portion of the lower casig-section; and Fig. 7, a bottom View of lan internal deiiector or spreader employed, said member ,serving also as a spacing member located between the hub of the casingl top and the central port-ion of the lower casl#ing-section.

In the construction illustrated, A represents a hub or base-member ot' a rotary casting; A1, a lower casing-section mounted on said hub; A2, the upper casing-section which is irmly secured to and rotatable with the lower casing-section; A, a spreader and spacing member interposed between the inlet with which the'upper casing-member provided and the water outlet with which substantially radial division plates conined ybetween the upper and lower casing-members; and A5, A, anti-friction bearings for the vertically disposedshaft A7 upon which the hub A is mounted.

The inlet to the machine is through a pipe lwhich is suitably connected with the casing-top A2 so as not to interfere with the rotationof the casing; the outlet for the peat or other solid material, which emerges in a plastic condition, is through a peripheral channel 2 between the peripheral portions ot the bottom and top sections of the casing; and the water outlet is through anA annular space 3 and radial passages t eX- tending therefrom which. are formed in the upper portion of the hub A.

The lower casing-section A1 'comprises a hub-portion 5 and an upwardly flaring conical wall 6 having at its periphery an upturned flange 7 upon which are removably secured Hangs-sections 8, 9 and l0. The hub A is firmly secured on the upper end of the shaft A7, and between the radial channels 4 or' thel hub are projections ll which .are received in recesses l2 with which ythe lower face of the hub-portion of casing-section A1 is provided. lChe upward projections '11 of the. hub A are cut away or recessed tion of the casingsection A1 sponding "iange 14, accommodated by said recess. of the casing-section A1 have a stepped engagement which prevent any rotation of said parts with relation to each other and which will also prevent any shifting from axial alinement. The central portion of the hub A is provided 'at the upper side of the hub with a socket which receives a threaded bolt or rod l5 which extends upwardly through the hubs of the spreader A3 and the top y"casing-section A2 and bind the parts together. The lower casing-section A1 is provided on its lower side with radial strengthening ribs 16. The upturned ange 7 is provided with `aninner peripheral groove or recess 17 which receives a corresponding annular lip with which the tlange-section 8 is provided. The iiange-section 8 is secured to thev fiange 'T by bolts 1S. The flange-sections 9 and 10 are joined by screw connections, as shown in Fig. l.

As has been indicated. the internal flanges 2S of the casing-top stop short of the axis of the casing-topi so that the inner vertical edges 4U of said flanges 2S are separated by a considerable space. as appears from Fig.

Outside of the annular separating zone 44 is a tapering annular coh'ivpacting zone 45 which terminates in the annulai peripheral channel 2. As shown, the flanges carried b v the peripheral members of the lower and upper casing-sections are so shaped and disposed as to cause the pe- A3 do not reach quite to the inner vertical edges of the division plates A.' so that a minparatively small unobstructed annular space 4.7 is afforded. which tends to equalize the passage of the water between the intel'- It is desiiableto construct the bearings A, A6 so as to allow a-ccrtam freedom of movement to the shaft AT in order that the i machine. which rotates at.` a very rapid speed.

This feature is not claimed. however. in the present application.

ln practice. it. is usually desirable to provide means for conveying the plastic peat, from the annular peripheral channel 2. lFor this` purpose. I have shown a plow or blade .32' dipping.r into the open upper end o f the peripheral channel '2 and provided with a ioo passage or conduit .53 through which the material is forced as it is shaved or cut from the. channel The plow is shown Aadjustably supported on inclined rods 54:, whose inclination corresponds With the inclination of the upper portion of' the channel 2, so thatthe plow or blade may be adjusted to cut to any desired depth in the channel The operation will bereadily understood from the foregoing detailed description.

Fluid, such as Water carrying peat in susn pension (ordinarily of about the consistency of cream), enters the lnachinefrom the top thi-'ouch the central vertical inletpipe 1, spreads into the chambers between the internal ribs of the casing-top, acquiring the the solid particles of the peat are thrown vated upon.

into the compacting zone 45 and then forced into the peripheral channel 2, forcing the preparatorily placed yielding packing ahead of it. The water, undr the head of fluid back of it, passes through the central outlet of the lower casing-section and emerges through the radial openings el of the hub A..

is the operation proceeds, the peat maintains the sealing,` ofl the channel soy that the .fluid cannot pass directly tl'iroughthe machine. h/l'oreover, as has been indicated, the division plates A4 prevent the iiuid from washing against the coinpacting peat in the conaiiaeting none 4&5, thus aiding` in preventing' the lal from being broken. VThe resistance ai" ded to the passage of the peat through. the channel 2 may be Varied by varying' the position of theploiv 52, and also may be varied by varying the extent. of the danges iianliing the annular perii'iheral channel. ,it is tosay, the removable flange sections muy be removed accordingto necessity or expediency, depending'` upon the quality and consistency of the fluid bei ng operlin the operatimi of the inachine, it is importantthat care be taken to have the fluid which is to be subjectedto centrifugal action of uniform quality-:nul consistency and also toprevent any fibrous substanci-s entering the machine with the fluid` such as might create minute channels tin-ouch the sealing' material -contained in the annular peripheral channel 2, v which vwould defeatthe objeetof the machine.

lVhile it in'eferred to employ a peri'iheral peat-outlet in the machine ivhich is coinpletely annular in forni, it is obvious that any' substantial peripheral outlet 'or outlets set forth,

through which the peatinay and which willserlve to render the peat self-sealing against the passage of the liquid behind. it,

would be within the scope of xny invention.

Also, While it is preferred to have the' peripheral channel 2 curved upwardly or made' angular (considering a vertical cross-section of the machine). it is likewise obvious thatL the peripheral flanges of the casing-sectigns of the machine may become.riuliulentary, the outlet channel for the peat. being sufliciently contracted in any desired manner to render the peat self-sealing in its passage therethrough.

T he foregoing detailed desril'ition has beengiven for clearness of understanding only, and no Vundue limitation should be understood therefrom. .v
