7 claims. (c1. gio-55) ber to the column I1 is a bridge structure I8 here The in vention relates to sedimentationapparatus, and has for one'of its objects to provide an improved modification of the apparatus described and claimed in the prior U. S. Patent No.`

1,947,429, granted February 13, 1934, on an application iiled by Darwin W. Townsend land .James Brower, entitled Sludge remover.

With the above and other objects in view which will'appear as the description proceeds,

lo the invention consists in the novel details ,of

construction and combinations and arrange.-

ments of. parts more fully hereinafter disclosed and particularly pointed out in the/#appended claims.

I5 Referring to theaccompanying drawings forming part of this specification, in which like reference characters designate like parts in all the views:

Figure 1 is a partial plan view of a sedimentation chamber with sludge removing apparatus constructed in accordance with the present' invention associated therewith;

Fig. Z is a vertical sectional elevational view of the parts shown in Fig. l, taken approximately on the plane indicated by the line 2--2 of vsaid figure;

Fig. 3 is an enlarged vertical' sectional view partly in elevation through thecentral column and driving mechanism for the sludge collector;

3o Fig. 4 is a still further enlarged vertical sectional view at right angles to Fig. 3, taken approximately` on the plane indicated by line 4 4 ofthe said figure; I

Fig. 5 is a vertical 'sectional view taken ap- .,5 proximately on the plane indicated by the line 5--5 of Fig. 4; and l l Figs. v6, 7 and 8 are detail perspective yviews of 'the several elements constituting a universal coupling between the power unit and the hollow 40 shaft o f the sludge collector.

In the said drawings, Ill indicates a sedimentation chamber preferably circular in plan and having side walls II and bottom wall 12, which latter-is provided with a centrally located sludge' 45 outlet I3 communicating with the-sludge conduit I4, as best shown in Figs. 2 and 3. Positioned upon the bottom-l2 surrounding the outlet I3 is the annular bearing member I5 to which is secured as by bolting or otherwise a spider-like ,-,0 base or pedestal I6. Surmounting this base or` pedestal and flxedly` secured thereto is a vertically extending column I 1 here shown as comprising 'a tube or pipe which extends upwardly to a point above the normalliquid level in the chamber.

55 Extending'from the side wall II ofthe chamshown as comprising a pair of spaced I-beams l I9 which are surmounted throughout the greater portion of their length by a plate 20 which constitutes a walkway over which attendants may '5 pass to the center portion of the chamber. -`The I-beams I9 are suitably secured at their outer ends to the side wall II and at their inner ends are provided with a pair of transverse channel irons or beams 2| which embrace and are rigidly 10 secured to the upper end of. the column I1. The said column thus serves as asupport for the inner end of the bridge structure and suitable brace members 22 may be provided at right angles to the beams I9 and extending therefrom to the l5 sidewalls II in order to brace the structure laterally.

' Hung from the beams I9 is an annular feed well 25 into which the influent conduit 26 discharges. This will, as best shown in Fig. 3, c'om- 20 prisesinner and outer

cylindrical members

21 and 28 joined by an annular bottom member 29, and the said inner member may, if desired,'be provided with an adjustable Weir 30 for controlling the height vof the liquid within the well. 'As 2.7

.will be readily understood by those-skilled in the art, the incoming liquid from the conduit 26 enters the well and lls the space between the

walls

21 and 28 until it overflows the Weir 30, whereupon it passes downwardly into the chamber sub- 30 stantially axially thereof. The

members

21 and 28 may be concentrically disposed, but if they are arranged eccentrically as shown in Fig. 3,

a larger volume capacity will be provided at the discharge port of the influence conduit 26, which will reduce the velocity of the liquid'and give a `more uniform lfeed thereof over the weir 30.

The sludge removing mechanism is in' general similar to that disclosed and claimed in the said Townsend and Brower PatentA 1,947,429, and comprises a pair of sludge conduits 35 each prol vided witha plurality of sludge collecting nozzles 36 into which the sludge is received under` the action of the hydrostatic head of. the li id-in the chamber. The inner ends of the cond ts 35 are 45 connected to a hollow manifold member 31 which encloses the spider pedestal- I6 as clearly shown in Figs. 3 and 4. The said manifold member i s preferably provided .with a lignum vitae or other similar bearing material 33v which rests upon the so outer portion of the bearingmember I5, whereby the manifold 31 and the conduits 35 are mounted for rotation ina horizontal plane adjacent the oor of the isedimentation chamber.' The maxilfold 31 has secured to its top a hollow shaft 3| 55 which surrounds the stationary column I 1, as

will ,be readily understood from the drawings.I

`mechanism at its lower end.

'Ihe driving mechanism for the shaft 39 comprises a suitable power unit 40 mounted adjacent the inner end of the bridge structure Il and preferably comprising an electric motor having associated with lt a suitable reduction gearing, since the sludge collecting conduits 35 are ordinarily rotated at a relatively slow speed, say from 5 to l5 feet per minute for the outermost sludge collector. The power shaft 4i of the unit 4l has keyed to it a driving vmember 42 (see Figs. 3 and 5), which is connected by means of a shear pin 4I to an element 44 of a universal coupling, which also includes a floating member Il having oppositely disposed lugs I6 and 41 arranged at right angles to one another and received respectively in companion recesses in the member M and the face of a pinion Il which is journalled on a stud Il carried by the supporting base or member 5l which in turn is supported by the inner end of the bridge structure Il.

, member 5l has an upst-anding annular flange 5I concentric with the hollow column i1 upon which is journalled a gear 52 which meshes with the pinion Il. As best shown in Figs. 5 and B upstanding lugs BI.

this 4gear is formed of two complementary sections which are bolted or otherwise secured tgether as will be readily/understood and which sections are each provid with a pair of spaced Mounted above the gear I2 is a noating disc or member 54 provided on its under surface with a pair of diametrically ldisposed lugs I receivable in the spaces between the lugs DI of the gear. 'Ihe upper face of the floating member 54 is likewise provided with a pair of diametrically disposed lugs 56 which are arranged at right angles to the lugs 55, as clearly shown in Fig. '7, and which-aregreceivable in recesses or grooves 5l provided in the under face of the driving'member I! which is splined to the upper end of the hollow shaft 39. 'Ihere is thu's provided a universal coupling for the shaft 39 which will take care of any'misalignment of the parts or wobbling of the shaft during rotation,

'as will be readilyunderstood.

The floor ofthe chamber Il may be provided with a drain opening .l communicating with the sludge conduit il and normally closed by a plug or other similar member 6I which, however, may be withdrawn should it be desired to drain the contents of the cha'mber independently of the sludge conduits 3l.

The slugs conduits :s may be supportedby' suitable. vertical and horizontal brace rods and the former of which extend angularly upward from' the conduits to the upper portion of the hollow shaft JI, while the latter extend angularly outward from said conduits to the transverse brace rods or pipes Il, as will be clear from Figs. l and 2.

While one form of the invention has been illustrated and described, it is obvious that those skilled in` the art iay vary the details of construction as wel] as the precise arrangement of parts without departing from the spirit of the invention, and therefore it is not'wished toY be limited to the above disclosure except as may be by the claims.
