THE NORRIS PETERS cu., WASHINCYON. D. C
WILLIAM L. DOLIER, OF PHILADELPHIA, PENNSYLVANIA.
CENTRIFUGAL MACHINE.
Speccaton of Letters Patent.
Patented Feb. 11, 1908.
Application filed March u126,1906. Serial No. 308.973.
4To all whom it may concern:
Be it known that I, WILLIAM L. DOLIER, a citizen of the United States, residing at Philadelphia, in the county 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 separating or drying apparatus, involving the principle, well understood in the art, of separating liquids from solids, liquids from liquids, etc., by rapidly rotating the materials to be dried or separated.
It is the object of my invention to provide an efficient and compact arrangement of centrifugal machine which may be conveniently driven by steam, or any suitable motor, there being provided for use when desired a heating chamber surrounding the usual curb, such heating chamber having steam circulating therethrough or containing an electrical heater or provided with any other heating agency.
It is the object of my invention to provide in a steam driven machine, means for heating the contents of the centrifugal basket and allowing the steam, either live or exhaust, to pass out through a hollow shaft upon which the centrifugal basket is mounted.
My invention residesv also in other features hereinafter described and pointed out in the claims.
For an illustration of one form my invention may take, reference is to be had to the accompanying drawing.
A pedestal 1, preferably of cast iron, has secured to its top, by bolts 3, 3, a casting of sheet metal curb member 4 provided with an inner wall plate 5 forming the curb proper surrounding the centrifugal basket 6. basket is secured by a taper ft upon the upper end of the hollow shaft 7 by means of the perforated cap 8 which is screw threaded and engages the screw threads at the upper end of the shaft 7. The shaft 7 has upon it at its lower end, the collar or shoulder 9 resting upon the superposed washers 10, 11 and 12 resting upon the casting or plate 13 secured by bolts 14, 14 to the lower end of the hanger 15 secured by bolts 16, 16'to the underside of the top plate 2 of pedestal 1. The hanger 15 is bored out and babbitted as shown at 17 to form a bearing for the outside of the hollow shaft 7. In the compartment 1S between the casting 4 and plate 2 and This l mounted upon the hollow shaft 7 is the steam turbine wheel 19 the steam for which is supplied by a nozzle 20 forming a continuance of the steam pipe joint 21. A -stufling box or gland 22 is provided in the bottom of the curb chamber to accommodate the passage therethrough of the hollow shaft 7.
Extending well up into the inside of the hollow shaft 7 is the pipe 23 which is screw threaded into the member 13 and has an elbow or other convenient joint 24 for attachment of a. suitable pipe leading away from the machine.
Small lengths of exteriorly screw threaded . pipes 25 and 26 communicate between the turbine wheel and compartment and the curb chamber and heating chamber respectively. These short lengths are accessible by hand holes having suitable covers 27, and are provided with caps 28 which may be interchanged in any suitable combination as hereinafter described.
The casting 13 has an oil tight joint with the member 15 so that the washer bearing of the hollow shaft is maintained flooded with oilwhich stands in the bearing 17 and fills more or less of the depression or reservoir 15 in the top of the member 15.
The operation is as follows: The steam issuing from the nozzle 20 strikes the blades of the turbine wheel 19 and thereby rotates the basket 6 and its contents at a high rate of speed. The exhaust steam from the turbine may, when the caps 28 are on the short pipes 26, (thus cutting off communication with the heating chamber 4 pass through the short pipes 25 into the curb chamber, which is closed by the cover 29, thus heating the perforated basket wall 6 and thence passing through the top of the basket into the interior thereof to further heating the contents and thence passing through theperforated cap 8 through the Vhollow shaft 7 and thence through the exhaust pipe 23 to some external point. The pipes 25 and 26 may be open at the same the steam to pass as just described, while a portion will pass into the heating chamber 4 and out through exhaust port 30. Or the short pipes 25 may be closed by caps 2S, and all of the exhaust steam may pass into the heating chamber 4 and thence through the exhaust opening 30. When the heating agent is passing through or inclosed in the heating chamber 4, heat is communicated through the curb wall 5 tothe interior of the time thus allowing a portion of means permitting the exit curb and through the perforated wall 6 of the basket and its contents. Or the turbine may exhaust directly to the outer air and live steam may be employed in either or both the curb chamber or the heating chamber 4. If desired the heating chamber 4 may be omitted., and the compartment 18 also.
In place of using steam as the heating agent in the chamber 4', an electric heater may be inclosed therein if desired, or any other source of heat may be employed. The liquid thrown through the perforations of the wall 6 of the basket is collected on the bottom of the curb and carried away by the pipe 31. yThe level of the outlet pipe 31 in the curb 5 should be lower than the' top of the short pipes 25, to insure that none of the separated liquid will pass into the turbine chamber 18.
What I claim is 1. In combination, a rotatable hollow shaft, a centrifugal basket secured thereto, a perforated cap within the basket and secured upon sald shaft, means for admitting a heating agent to said basket, and a pipe extending into said hollow shaft, whereby said heating agent may pass out through said cap,
hollow shaft and pipe.
2. In combination, a rotatable hollow shaft, a centrifugal basket secured thereto, a perforated cap secured upon said shaft within said basket, an exhaust pipe communieating with said hollow shaft, a steam motor driving said hollow shaft, and means for admitting exhaust steam from said motor to said basket, said steam adapted to 'heat the contents of the basket and to ass out through said cap, hollow shaft an exhaust pg. In combination, a rotatable shaft, a centrifugal basket secured thereto within a curb chamber, the rotatable element of a fluid motor secured upon said shaft in a chamber independent of said curb chamber, and means for permitting escape of exhaust fluid from said motor after passing through said basket.
4. In combination, a hollow rotatable shaft, a centrifugal basket secured thereto Within a chamber, the rotatable element of a fluid motor secured u on said shaft in a chamber independent ofp said chamber surrounding-said basket, means for admitting a heating agent to the basket chamber, nand of said heating agent through said hollow shaft.
5. In combination, a rotatable hollow shaft, a centrifugal basket secured thereon,
the rotatable element of a fluid motor secured upon said shaft, and means for directing exhaust fluid from said motor through said basket and through said hollow shaft.
6. In combination, a centrifugal basket, a rotatable hollow shaft supporting said basket and opening into the same, means for admitting heating fluid to said basket, and a fluid tight connection with said rotatable shaft, whereby said heating agent may pass out through said shaft.

In combination, a rotatable hollow said basket, and a pipe exshaft, a centrifugal basket secured thereto and into which said shaft opens, means for admitting heating agent to said basket, and a stationary pipe extending into said hollow shaft, whereby saidheating agent may escape through said pipe and shaft.
