LIQUID FILTERING AND DELIVERING APPARATUS.
To all whom it may concern.'
Be it known that I, FORREs'r E. BINGHAM, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements inLiquid Filtering and Delivering Apparatus, of which the following is a specication.
This invention has for its object to provide apparatus adapted particularly to filter oil which has become charged with impurities and foreign matter during its use as a lubricant, and to deliver the iiltered liquid at any suitable point, permitting it to be again used. A
The invention is embodied as a whole in a liquid filtering and ldelivering apparatus -poses of the invention, all which are hereinafter described and claimed. A l l Of the accompanying drawings forming a part of this specication,
Figure 1 represents a vertical sectional view of an apparatus embodying the invention;
' Fig. 2 represents a` horizontal section on line 2-2 of Fig. 1; 1
Fig. 3 represents a top plan view of the rotor; p

Fig. 5 representsa sectional view'of the rotor, a portion of the hub being broken away;
Fig. 6 represents a sectional view of the rotor, showing the hub unbroken;
Fig. 7 represents'a vertical section of the upper spindle bearing hereinafter referred Fig. 8 represents a section on line 8-8 of Fig. 7 y Fig. 9 represents a fragmentary sectional view ofthe .pump casing without the rotor.
Specification of Letters Patent.
Patented June 19, 1917.
Application led November 8, 1916. Serial No. 130,165.
The same reference characters indicate the same or similar partsin all the views.
In the drawings, 12 represents a vertical spindle'driven by a suitable motor, a portion of the casing of which is shown at 13 in Fig. 1. Any suitable type of motor may be employed adapted to rotate the spindle at a relatively, high rate of speed, say from twelve 'to fifteen hundred revolutions per minute,
A lower bearing for said spindle is shown at 14, said bearing preferably forming a part of the fixed centrifugal -pump casing hereinafter described. An upper spindle bearing is shown at l15, and is preferably provided with a lflange 116 supported as hereinafter described by` thev said pump casing, the bearing 15 being provided with a series of vertical passages 17 (Fig. 7
adapted to permit oil ,to flow by gravity from the bottom of a lilter curb 18 tothe said pump icasing.
J The centrifugal pump casing is of generally circular form, and is preferably composed of a lower section 19 and an upper section 20, said sections being provided with marginal ianges connected. by bolts 21. The opposed sides of the sections are recessed to collectively form a rotor chamber 22 (Fig. 9), a circular oil conducting passage 23 surrounding said chamber, and a passage 24 connecting the chamber 22 and passage 23.
The upper section 2O is provided with an annular seat 25 to which the bearing flange 16 is bolted. .u
The bottom of the curb 18 bears on and is attached to the flange Y1 6, whichA consti tutes a seat for said bottom. The curb bottom is open at itscenter and communicates with the passages 17, which collectively constitute an outlet for filtered oil from the curb 18, and an inlet admitting the filtered oil to the central portion of the rotor chamber. To the upper end of the spindle 12 is attached a collar 26 having a downwardly projecting tubular extension 27 surrounding the bearing 15 and provided 'with an outwardly projectingl flange 28. The Hange extension 27 supports a filter basket and imparts rotation from the spindle to said basket. f
The filter basket, as here shown, 1s composed of a perforated annular inner member 29, a perforated annular outer member 30, and a perforated annular intermediate A plied by winding a layer of cloth on the outer surface of the member 31, thus forming aalaminated filter 33. The members 2-9 and 31, the flanges of which are riveted together at 32, are separable as one part from the member 30, so that the cloth may con-v' veniently be wound on and removed from the member A31 when it is removed from the member 30. The attachment of the outer member 30 to the driving fiange 28 by rivets 32a causes a positive rotation of the said outer member, the frictional connection between the outer member 30 and the intermediate member 31 caused by the lami- .nated filter 33 being sufficient to cause the intermediate and inner members ofthe basket vto rotate with the outer member.
Oil to be filtered is admittedto the filter basket through a hopper or funnel4 34 located on the cover 25 of the curb, and receiving oil throughv a conduit 36.
In the rotor chamber 22 is located a rotor, the form and construction of which are best shown by Figs. 3, 4, 5 and 6. Said rotor preferably includes an annular hollow portion 37 having a hub 38 rigidly secured to the spindle, said hub having a tapering oil conducting portion 38a. The rotor also includes an annular top portion 39 which is of dished or frusto-conical form, and is provided with tangential curved buckets 40, eX-. tending across the space between the bottom and top portions- 37 and 39, the rotor being preferably castin a single piece. Said buckets subdivide the space between the portions 37 and 39 into tangential passages through which oil is forced centrifugally outward into the conducting passage 23 surrounding the rotor chamber. The central opening of the rotor section 39 is enlarged,
so that oil conducted from the curb by the vertical passages 174 is discharged within the buckets 40.
'It will now be seen that', when the spindle 12 is rotated, the filter basket and the rotor rotate in unison lwith the spindle, so that oil delivered at the center of the lter basket is thrown 'centrifugally outward into the curb through the filtering materials or bodies above described, they filtered oil owing through the vertical passages 17 into the central portion of the rotor chamber and being then thrown outward centrifugally by the rotor into the oil conducting sage surrounding said chamber an passage 23. Said passage, as shown by Fig. 2, is preferably eccentric to the rotor and is provided with a marginal oil delivering outlet 41, preferably arranged tangentially, said outlet forming a part of a delivering conduit, which may extend to any desired elevated point. The filtered oil may therefore be conducted to an elevated tank and stored therein for further use.
