GENTRIFUGAL MACHINE.

Specification of Letters Patent.-

Patented Mar. 23, 1915.

Application filed May 1c, 1913. Serial, mf 788,002.

To all whom it may concern.-

Be it known that I, WILLIAM L. DOLInn, residing in the city of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Centrifugal Machines, of which the following is a specification.

My invention relates to centrifugal .machines for the extraction of liquids from solids, fabricsor fibrous material, and for similar uses.

My invention resides in apparatus of the character above referred to in which the centrifugal drum or basket is rotated by a steam turbine or impulse wheel so associated with the basket that the steam or motive fluid after impact u'on the motor blades or buckets passes directly into the basket. And it is afurther feature of my invention that, particularly for machines of small size, the motor blades or buckets are formed in parts formed on or struck out from the basket with complementary parts formed on or struck out from the bottom member of the bowl or basket.

My invention resides in the features here; inafter described and claimed. 1

For an illustration of one of the many forms my invention may take reference is to be had to-the accompanying drawing, in which:

Figure 1 is a vertical sectional view, arts in elevation through a machine embo ying my invention. Fig. 2is a fragmentary horizontal sectional view illustrative of the structure shown in Fig. 1.

The centrifugal bowl, drum or basket B, walls perforated and having I having its side the top inwardly extending flange F is secured at its lower margin b rivets r to the upturned flange f of the ate or disk D which may be the bottom u the basket B.

The disk or plate D, and therefore the bowl or drum B, is secured to the shaft S by nut N screw threaded on the upper end of the shaft 5 and pressing together the collars a and 1) between which the bottom D is clamped, the collar B thrusting against the shoulder on the upper end of the shaft S. A ball or other suitable bearing C is provided, the shaft S' having also bearings E and G in the member H secured to or integral with the bottom I of the casing J which incloses the centrifugal basket B. The cas ing J is cast integral with or otherwise supported by the pedestal P.

is an oil cup or reservoir from. which oil is fed through pipe Pinto the cavity or chamber 0 in member H, the chamber a being closed at its bottom by the screw threaded plug d. Oil rises through chamber a, bearing G, chamber e, bearing E, into chamber 9 maintaining the bearing 0 flooded with oil.

From the lower margin of the basket or drum B are cut or punched, as along three sides of a parallelogramor rectangle, the blade or vane members 0 which are then bent inwardly as shown in Fig. 2. Similarly blade or vane members o are formed upon or attached to upturned flange f of the bottom or plate D, as shown in Fig. 2, vane members '1). and v being complementary to each other to 'makecomplete vanes,

blades or buckets of a rotor of aturbine or motor, the spaces or openings in the members Band f from which the vanes are bent out forming passages for the steam or other motive fluid, as shown in Fig. 2. The m0- tive fluid is supplied through the nozzle L extending through the side wall of easing J in a direction to deliver steam into the buckets or vanes as indicated.

The operation is as follows: Oily waste or any other material to be treated or op erated upon is placed inside of the drum or basket B and the cover K replaced into position'shown. Steam is then delivered to the nozzle L from any suitable source, as a steam boiler, and steam strikes the vanes or buckets as indicated causing rotation of the basket B at high speed, whereupon, due to centrifugal action, liquid is separated from the contents of the basket B. It will .be

noted that the steam strikes upon the vanes or buckets and passes from their inner parts 4) directly into the basket B through the false bottom M, which may be a perforated metal plate, or may be a sheet of wire gauze. This steam escaping directly into the basket assists in separating the oil, for example,

from the waste, due to the heating effect, and possibly other effects. The steam which does not condense in its' passage through the basket after leaving the motor escapes into the casing J and thence outwardly through the exhaust pipe X. The water of condensation and the oil or other liquid sepa rated from the contents of the basket collect in the bottom of the casing J and pass into the trap T'whose upper orifice communicates with the interior of the casing J. The liquid material flows into the trap T and downwardly around the web or diaphragm U and thence out through the aperture V to any suitable tank or other collector.

It is to be understood that other structures than the one illustrated may be used whereby the steam passes directly from the motor vanes or buckets into the interior of the basket B. Thus, for example, for larger machines, where greater efficiency of the motor is desired, the blades or vanes may be of proper curved shape and cast integral upon a member similar to the bottom D at the outer margin thereof, and the basket or drum disposed upon the upper edges of such blades or buckets, and in this case also steam escaping from the buckets or vanes passes directly upwardly into the basket B.

What I claim is: p

1. The combination with a centrifugal basket, of a bottom therefor to which said basket extends, said basket having perforations at said bottom, motor buckets or vanes disposed at said perforations above said bot tom, and a false bottom within said basket disposed above said vanes or buckets.

2. The combination with a centrifugal basket, of a bottom therefor to which said basket extends, said basket having perforations at said bottom, motor buckets or vanes disposed at said perforationsabove said bottom, a false bottom within said basket disposed above said vanes or buckets, and means for delivering motive fluid to said vanes or buckets to drive said basket, said motive fluid after impact upon said vanes or buckets passing upwardly into said basket through said false bottom.

. 3, The combination with a centrifugal basket, of a bottom therefor, motor vane or bucket members struck out from said basket,

an upturned flange secured. to said bottom, a

basket, of a bottom therefor, a flange on said bottom, said flange and said basket having registering openings, and motor vanes or buckets disposed at said openings.

5. The combination with a centrifugal basket, of a bottom therefor, aflange on sai l bottom, said flange and said basket having registering openings, motor vanes or bucket members disposed at said openings, a part of each vane or bucket carried by said basket, and a complementary part of each vane or bucket carried by said flange.

6. The combination with a centrifugal basket, of a member secured thereto, motor vane or bucket members, a part of each vane or bucket member extending in one direction from said basket, and a complementary part of each vane or bucket member extending in another direction from said first named member.

7. The combination with a centrifugal basket, of separate bottoms therefor, motor vane or bucket members disposed between said bottoms, a rotary shaft supporting said basket, and bearings for said shaft disposed beneath said basket and said bottoms.

In testimony whereof l have hereunto affixed my signature in the presence of the two subscribing witnesses.

WILLIAM L. DOLIER.
