Specification of Letters Patent.

Patented Julyr 5, 1910.

Application led September 14, 1908. Serial No. 452,954.

To all whom it may concern:

Be it known that I, Hnnnr E. MORLEY, a citizen of the United States, residing at Detroit, in the county of Wayne, State of Michigan, have invented certain new and useful Improvements in Strainers or Separators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the gures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in strainers or separators for removing or separating solids or extrinsic matter from liquids, the apparatus being especially designed for use in the manufacture of soda-ash, paint, cement, etc., and consists in the construction and arrangement of parts hereinafter more fully set forth and pointed out particularly in the claims.

The object of the invention is to provide a machine of the character described, of comparatively simple and inexpensive construction, wherein the arrangement is such as to enable a rapid and thorough separation of extrinsic matter from liquids, provision being made for removing the matter separated out of the liquid to prevent an accumulation thereof and a consequent impairmentof the strainer or separator.

The above object is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is an elevation of an apparatus embodying my invention. Fig. 2 is a hori- Zontal section as on line 2 2 of Fig. 1. Fig. 3 is a perspective view of one half of the inner straining or separating disk, looking at the inner face thereof. Fig. L1 is an enlarged fragmentary view in section of the gearing for driving the separating disk, showing also the manner of securing the straining materials to the opposite faces of said disk. Fig. 5 is a transverse section through the outer case and the separating disk, as on line 5-5 of Fig. 2. Fig. 6 is a fragmentary view of a portion of one half of the separating disk, showing the screen, filter felt and wire cloth thereon.

Referring to the characters of reference, 1 designates the lower half of the outer circular case which is composed of two semicircular concavo-convex plates oined at their motion to the separating disk,

peripheries and forming a closed receptacle or chamber 2 for the liquid substance into the bottom of which leads an induct pipe 3. To maintain the liquid substance at a proper `level in said chamber, an educt pipe 4 leads therefrom at a point below the horizontal center of the outer case.

The upper half of the outer case is also composed of semicircular concavo-convex plates 5 which are secured together at their peripheries and are mounted upon and secured to the lower plates 1 to form a complementary portion of the circular case which is convexo-convex in cross section. Through the upper opposite walls of said case or through lthe semicircular plates 5 forming said walls are segmental apertures 6 covered by a screening 7 for the purpose of admitting air to the upper portion of the interior of said case.

Within the fixed outer case is a rotative separating disk composed of two circular plates 8 concavo-convex in form which are secured in opposed relation on opposite sides of a circular dividingplate 9, said opposed circular plates 8 forming a substantially convexo-convex separating disk which conforms to the shape of the outer case. The marginal portions of the circular plates 8 are bolted together through the perimeter of the plate 9 by means of the bolts 10, said plate 9 serving to divide the interior of the separating disk into two independent chambers located on opposite sides thereof. Secured to the central portion o f each of the plates 8 of the separating disk is a hollow journal 11, said journals being supported in bearing boxes 12 projecting from the opposite sides of the outer case.

Passing through the hollow journals 12 are the educt tubes 13 which are non-rotative and about which the journals 11 revolve.

The inner ends of the tubes 18 communicate with the opposite divisions of the separating disk through the apertures 14, as clearly shown in Fig. 2. To prevent leakage around the tubes 13, suitable stuffing boxes 15 are provided. The outer ends of the tubes 13 are adapted for connection with suitable pumps, not shown, for the purpose of creating a partial vacuum in the upper portion of the-separating disk and for drawing outwardly through said tubes the filtered or strained liquid.

For the purpose of imparting a rotary the plate 9 which extends each side lof said ing disk.

is provided upon the periphery thereof, beyond the margins Yof the plates 8, with gear teeth 16 which mesh with a pinion 17 journaled on a shaft'lS within a housing 19 formed in the outer case, saidy shaft being-driven throughv the medium of a suitable pulley 20 mounted thereon g` the the shaft 18 beingregulated to iinspeed of part a slow rotary movement to the separat- It will be seen on referring to Fig. 3 that each of the plates 8,which comprise the hollow separating disk, is provided on its inner face with whose inner edges bear against the face of the dividing plate or partition 9, and in conjunction therewith separate the chamber on partition into four divisions, saidwebs as the separating disk revolves, serving as buckets which carry upwardly and discharge the liquid, which has passed through the separating disk, into the b educt tubeslS through the openings 14 from whence it is conveyed away. It will also be noted on referringto Fig. 3, that each of the plates 8 is provided with a plurality of apertures 22 through the openings for the' through the walls vide for straining wallthereof to afford passage of the liquid of said plates; To prosaid liquid or separating the ext-rinsic matter therefrom, the outer faceof each of the circular plates 8 is covered first with screen 23, then with a layer through `slots in said Y' through openings in thewalls V i flower portion Vof "margins are in of filter felt 24 upon said screen, over which of wire cloth 25. These is a third layer layers or coverings permit the passage of the liquid through the walls of the separating disk but prevent the passage of the solid matter carried by said liquid which remains,

upon the outer surface. of the wire cloth.

The several layers of wire cloth and felt are secured at their outer margins by a ring 29 which is bolted to the perimeter ofthe plates 8 by means of the bolts 30, while 'the inner like manner` secured bya ring 3l fastened by the lbolts 32. To remove the accumulation of the extrinsic matter from the surface of the wire cloth, the knives 26 are employed supported at the upper edges of the troughs 27 by means of fastening bolts 28 which pass knives to permit of Said knives project of the lower edges extend their adjustment.

half'of the outer case andA their vinto contiguity with the wire cloth upon the 'outer facesjof the 'separating disk, so that as saidv disk revolves, the matter separatedv from "the, Yliquid which collects upon the outer surface ,thereofis removed by said knivesand discharged into the troughs '27 When the apparatus is in operatioinnthe the separating disk is submerged in the liquid within the,lower part of the outer case. It will be noted that the radially extending webs 21 rotate within said 'the dividing webs 21 cross the educt openings 14 leading from the opposite sides of said disk, so that each of the four compartments into which 'the opposite sides of said Vdisk are divided, is in independent communica-ti'on with one of the educt tubes 13. When the pumps, not shown, but which are connected with said tubes, are started, the

air is partially exhausted from the upper portion of the separating disk on each side, creating aAV partial vacuum, which relieves the atmospheric pressure withiny said disk sufficiently to cause.. the liquid sur oundinfr its lower arc to pass through the submerge portions of the Walls thereof, said liquid which passes into the interior divisions of Vsaiddisk being drawn or discharged into thetubes 13 as the separating disk revolves, and is vdisposed of in any suitable manner.

.It will be noted that thel creation of a partial vacuumA Within the separating disk y means of the suction pu1nps,.will have a tendency to cause an inflow of. air through the screens 7 in the upper portion of the outer case and through the upper portion of the walls of the separating disk. This passage of the air through the walls of said disk, serves to partially dry the matter separated from the fluid thereby facilitating kthe removal of said matter by the knives j26 as the separating disk revolves. ,Y Byl means of limeV of .liquid comparatively this apparatus a large volmay be handled within a short time, out of which the extrinsic matter may bey readily sepa-rated.

Having thus fully set forth my invention, what I claim as new and desire to secure by Letters Patent, is
