CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 272,185, dated February 13, 188.3. Application filed November 25, 1882. (No model.) I l To all whom it may concern Be it known that we, OLUF SIGURD ANDER- SEN and 'PHORVALD TAGE AGATHON HAN- SEN, subjects of theKing of Denmark, residing at Uopenhagen, Kingdom of Denmark, have invented certain new and useful Improvements in Centrifugal Machines; and we do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the'same, reference being had tothe accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification, and in which- Figure l is a vertical sectional view. of our improved centrifugal machine, and Fig. 2 is a horizontal sectional view ot' the same on line w, Fig. 1.

Similar letters of reference indicate corresponding parts in both the figures.

Ourinvention has relation to centrifugal machines for separating.;` the heavier and lighter parts of uids; and it consists in the improved construction, combination, and arrangement of parts of the same, as hereinafter more fully described and claimed.

In the accompanyingdrawings, the letter A represents a receiver,.which may be spherical, conical, or cylindrical, as desired, and is fastened to and revolves with the hollow shaft B, which turns in bearings C inthe frame D.

The bottom E of the receiver is removable, and is held in place, its beveled edges bearing againstthe beveled edges of the bottom llange, F, by the pivoted arms Gr.

The shaft B,upon which the receiver is fastened, is hollow at its upper part till where it enters the receiver, where it opens out into the same by two or more short tubes, H. The fluidV to be treated enters the receiver through this shaft from a suitable receptacle above.

Inside the receiver, and fastened to the sides of the same, are partitions I, corresponding in number to theinlet-tubes, and extending about half-way into the receiver. Y These partitions serve to force the fluid to rotate with the receiver, so that the heavier and lighter parts may beseparated.

To the bottom flange are fastened two or morel bent tubes, J, which pass through it,

while their inner ends are fastened to the bolt ou flange near the sides by means of clamps K. The ends of these tubes are closed; but near the ends, in thse sides of the tubes, are small` apertures L, which admit the heavier parts of the tluid, which are forced ont toward the sides, to flow out through, the tubes and into an annular vessel, M, from which it is discharged through an opening, N.

The bottom AE has a downward-projecting funnel-shaped flange, Q, Which, with a Haring collar, O, fastened to the shaft, forms an annular nozzle, through which the lighter parts of the fluid, which collect near the center, dow out into an annularv vessel, P, which stands immediately around the shaft.. and has an opening, It, at its bottom, through which the contents may be removed.

It is preferable to divide the vessels M and P diametrically, so that the two halves may be removed, while the corresponding halves of vessels M andP may be made in one only, separated by a cylindrical partition. The two halves of the vessels are held together by hoops S, having piutle-hinges T, by which the'ymay be opened and closed.

To prevent any accident or interference while the machine is in motion, the receiver and the vessels M and P are surrounded by a drum, U, of heavysheet metal, hinged to the frame D and closed in front by eyes and pintles V, Whilethe top is covered with a head, WV.

The lower part of the shaft B rests upon a frictiondisk, X, of wood or other suitable material, which is fastenedin a conical collar, Y, fastened upon the lower shaft, Z. By this friction-disk the motion from the lower shaft, Z,

which is rotated by the drivepulley a, is communicated to the upper shaft, B, and the shaft and receiver are started gradually, and will stop gradually, although the lower shaft may be started or stopped suddenly.

The conical collar Y turns in an inverted conical box, b,the outside of which is'recessed at c for the reception of a rubber packingring, d, which ring allows the shaft and box sufficient play. The upper end of the'box b is held in place by a ring, e, the outside of which is screw-threaded, and fits in a screw-threaded flange, k, which is fastened to the bearing C by means of screw-bolts f. The inside ofthe ring eforms a cup for the application of lubricating material, which is caught up by an annular recess in a lower flanged sleeve, g, which is bolted to bearing G, and supports the lower part; ofthe conical collar Y, and is carried out through a duct, h. The upper bearing is of the same ronstrnction as the lower, and the lower shat't, Z, is turning in a lower bearing, i, having an adjustable steel point, j, upon which turns the steeled end ofthe shaft.

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States- 1. In a centrilugal machine for separating liquids, the receiverA,|nounted upon shaft B, and having beveled bottom tiange, F, and removable bottom IC, having beveled edge and discharge-nozzle Q, and held in place by piv? oted arms G, substantially as shown and set i'orth.

2. In a centrifugal machine for separating liquids, the receiver A, having bottom flange, F, removable bottom E, having tlange Q, inlet-tubes H, partitions I, outlet-tubes J, closed at their ends, and having side apertures, L, and pivoted arms G, substantially as shown and set forth. v

3. In a centrifugal machine for separating liquids, the combination ot' the receiver A, having removable bottom E, having funnelshaped lange Q, partitions I, and tubes J, with the shaft B, hollow at its upper part, and having;1 tubes H and Haring collar 0, substantially as shown and set forth.

4. In a centrifugal machine for separating fluids, the combination ofthe receiver A, having curved outlet-tubes J and flaring nozzle Q. and the shaft B, having flaring collar 0, with the annular vessels M and P, having outlets N and R, substantially as shown and set forth.

5. The. combination of the shaft B, having conical collar Y, with the bearing;` consisting ot' ring b, having recess c, provided with rubber packing-ring d, screw-threaded ring e, forming a lubricator-cnp, tange K, fastened byscrew-bolts f, and flanged sleeve fj/forming an annular recess,\vhich has outlet-duct h, substantiallv7 as shown and set. forth.

6. The centrifugal machine for separating fluids, consisting of the receiver A, shaft B, turning in bearings C in the frame D, annular vessels M and P, having hoops S and pintlehinges T, and drum U, having head W, and c ves and bolts V, all constructed and combined to operate substantially as and for the purpose shown and set forth.

In testimony whereof, and that We claim the foregoingas our own invention, we have hereunto ajxed. our signatures in presence ot' two witnesses. I
