CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 559,059, dated April 28, 1896. Application filed September 16, 1895. Serial No. 562,709. (No model.)

T0 at whom it may concern,-

Be it known that I, ADAM I-IEBERER, a citizen of the United States, residing in the city of Alameda, county of Alameda, and State of California, have invented certain new and and for the separation of liquids and solid matter and substances from each other in the various arts and manufactures.

The present improvements comprise a cylindrical separator mounted for rotation upon a horizontal axis and means combined therewith for tilting it at an angle to facilitate the removal of the solid matter or substances re maining at the end of its operation, and means for carrying away the liquid extracted during the operation, together with other parts and details of construction producing a simple, efi'ective and rapidly-operating machine, as hereinafter more fully described, and pointed out in the claims.

The nature of the said improvements and the manner in which I proceed to construct a centrifugal machine for sugar-works in accordance therewith are fully explained and set forth in the following description, reference being had therein to the accompanying drawings, forming part of this specification.

Figure 1 is a side elevation of the machine, with the cylinder and parts of the framework shown in longitudinal section. Fig. 2 is a side View of the portion of the conductingpipe through which the solution to be operated on is conveyed from the supply-tank into the cylinder, the interlocking ends of the two sections of pipe forming this conductor being here shown in top view. Fig. 2 is a side view in detail showing the construction of that section of the conducting-pipe which is attached to the cylinder. Fig. 3 is a front elevation of the machine, taken from the left hand of Fig. 1. Fig. 4 is a rear elevation taken from the right hand of Fig. 1.

A A are the upright timbers, and B B horizontal timbers, of a suitable stiff frame to carry and support the working .parts.

0 indicates a circular frame or carriage, formed. of two flat rings 0 fastened together at proper distance apart, and (J O are blocks I plates 03 at regular distances apart around the circle, and E is the centrifugal cylinder of which this frame or carriage is the princi-' pal support.

Two of the flanged wheels D are placed below and two above the line of the trunnions,

and on these four wheels the cylinder is rotated by means of power applied at one end of the cylinder. The position at such time of operation is horizontal, but when at rest and during the cleaning out the cylinder is tilted by elevating one end. At such time the trunnions c of the swinging frame orcarriage form the center, the parts being so balanced and arranged that the cylinder swings readily on the center.

E is a circular rail extending around the body of the cylinder and fastened to the outer surface to form a track for the wheels. The

head or bearing portion of the rail is cylindrical'in cross-section, and the rims of the wheels between the fian ges are of corresponding shape to set over the rail, by which means the cylinder is confined in place in the frame or carriage and is kept from slipping through the opening when tilted at an angle.

The body of the cylinder is constructed of an outer closed non-perforated shell 1 and an inner shell 2,with perforations or apertures 3 3 all aroundthe circumference. The two shells set one inside the other and are of different diameters, leaving an annular space 4 between the two shells. The ends of the cylinder are formed of flanged rims or heads, of which one is a closed head 5, having a central aperture 6 for a hollow shaft F, and the other is a ring 7, with a flange 7% Thus the cylinder is open to the outside at one end, but is closed at the other end, and the annular space is closed at both ends by the flanges or parts of the rims that set between the two shells. The rim at the closed end stands outward beyond the body of the cylinder and has pas sages 8 8, that run toward the center and thence longitudinally through the flange and open into the annular space. These passages form outlets for the liquid from the space 4 through the head to the outside, and the same are arranged at proper intervals apart all around the circumference.

G is a circular trough that surrounds and covers this rim of the cylinder-head to catch and carry away the liquid as it is discharged from the annular space through the passages before mentioned, and H H are conductors leading from below the trough to any distant point and connected with the trough by suitable couplings or means that allow the trough to belifted with the cylinder as that end is raised and to be lowered into position when the cylinder is brought back to place in the frame. The construction and arrangement of this trough is well shown in Figs. 1 and 3 of the drawings. The general form of the trough is circular, but at the bottom it has a rectangular shape with a flat bottom 9, and the top and ends of this rectangular portion G are closed in. There are outlets in the bottom with surrounding rims or tubes 12, that extend downward and fit closely into the upper ends of the conductors H on the frame,

pendicular sides being made shorter than the other side, as shown inFig. 1, its edge g will clear the rim of the cylinder-head and allow the trough to be taken off the cylinder when it is necessary to reach the outlet-passages. The opposite end of the cylinder is closed in around the margin by a removable plate or cover I, having an open center and a flanged rim with locking-lugs 14, shaped to fit over and engage the rim of the cylinder-head, the rim being slotted, as shown at 13, Fig. 3, to let in the lugs behind the rim. When this cover is in place, the lugs are caused to engage the back of the rim, as shown in Fig. 1, by rotating the cover. readily placing and taking off the cover it is provided with handles I I The hollow shaft E is fixed in the cylinderhead, and extending inwardly nearly the entire length of the cylinder it is connected at the outer end with a feed-pipe or supply-pipe, by means of which the solution to be operated on is fed into the cylinder. The shaft is perforated with holes f and its inner end is closed by a cap F. Power is applied to the part of the shaft outside in any suitable manner to rotate the cylinder. Usually this is done by means of gearing, and in the present construction the cylinder-shaft is connected by friction-gears 15 16 with a driven shaft K.

mounted on the stationaryframework.

For'this purpose and for The manner of connecting the hollow shaft to and disconnecting it from the supply-pipe L will be understood by referring to Figs. 1, 2, and 2.

The stationary pipe L is connected with the outlet of a supply-tank X, and is provided with a gate L for regulating the fiow of the solution into the cylinder.

M is a flanged head on the outer end of the pipe L, and N is a head of corresponding form on the adjacent end of the hollow shaft, the faces of these two parts being fitted to form a close joint when brought together, being also finished with interlocking couplings that draw them together and produce a tight joint.

The form of coupling which I prefer to use is composed of the hooks 17 17 on the end of one part and the inclines or wedge-shaped faces 18 1-8 on the sides of the other part. This coupling is separated when the cylinder is tilted from that end, and is brought together and a tight joint formed when the cylinder is brought down again to the horizontal position.

In order to permit rotation of the hollow shaft, that portion between the driving-gears and the coupling before mentioned has a telescopic joint 19, one part of which carries the coupling on the outer end and is fitted to the end of the main portion of the shaft in suitable manner to secure a tight joint and at the same time allow the moving part to turn freely on the stationary part.

P is a bearing-block supporting the shaft L, and R R are fixed guide-rails between which the bearing-block is confined, and is fitted to slide up and down. The guide-rails are bent to a quadrant shape, with the outer edges struck from a center at the trunnions O and a rack R is formed on each rail to engage pinions S S, mounted on the bearingblock P. The shaft 22 carrying the pinion is furnished with a long bearing 25 in a bracket Eton the top of the block P, and a hand-wheel T is made fast on one end of the pinion-shaft for working the pinions. These parts form a simple and efficient means of moving the bearing-block in the fixed-quadrant to raise and lower the back end of the cylinder in the frame.

The joint on the hollow shaft is situated in the bearing-block, and the part L is prevented from turning accidentally, whenever the bearing-block is raised and the parts of the coupling are separated, by providing lugs 23 23 or projections on the sides of the section of pipe and on the face of the bearing-block. A limited extent of longitudinal movement of this section at the joint 19 allows the faces of the couplings to be drawn up by the inclines and hooks, and thus secures a tight joint.

The machine thus constructed is especially adapted for sugar-works, but it can be used as well for separating liquid from solid mat ter and substances in other arts and manufac'tures where pressure is not required.
