CENTRIFUGAL SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 668,747, dated February 26, 1901. Application tiled February 21, 1900. ySerial No. 6,066. (No model.)

To all whom it may concern:

Be it known that I, PHINEAS H. ADAMS, a citizen of the United States, residing at Chi.- cago, in the county of Cook and State of Illinois, have invented a new and usefullmprovement in Centrifugal Separators, of Which the following is a specification.

My invention relates more particularly to improvements in theart of centrifugal separation or concentration of material While in anely-dvided state and in the presence of or mixed with water; and it consists in various details of construction of a machine for usein this art.

In centrifugal apparatus which are rotated at comparatively high speeds and which consist of heavy'vessel's and other rotatable parts or contain considerable Weights of the mixture treated the vibration 'which arises is liable to be destructive to the supporting-shaft and bearings and unfavorable to the best operation of the machine; and one of the objects of this invention is to provide the type of machine having' a plurality of rotating parts with yielding supports, by which the objectionable vibration is absorbed.

Another object of the invention is to so support a centrifugal separator which rotates about a vertical axis that the shafting and belting for actuating its moving parts shall be removed from above the door of the mill, Where they are dangerous and occupy much space.

The above and other ends are attained by the mechanism hereinafter described and claimed.

In the drawings, Figure 1 illustrates a central vertical longitudinal section of my improved separator; and Fig. 2 is a sectional detail of the bearing 22, taken at right angles to Fig. 1. 4

10 designates a rotatable treatment vessel or cylinder having its. axis vert-ical and consisting of two heads 10a 10b and an intermediate cylindrical or frusto-conical portion, the lower head 10a being provided with a downwardly-projecting hollow shaftor hub 11, stepped on antifriction-bearing'12, carried by a movable plate 12, Which slides freely upon a portion of the base of the machine corresponding in shape to the under side of the plate. The upper head 10b of the vessel is provided With a feed-receptacle 13, into which delivers a pipe or conduit, the material fed thereby passing through feed-orifices 14 in the head ofthe vessel, at or near the periphery of the receptacle. After treatment within the vessel the separated material is dis- -charged through peripheral orifices 15 near the lower end thereof into the outer section of a double trough 15a, the inner section of which receives any excess of liquid or any splashing or back pressure of the pulp discharged through openings 15b in the head of the vessel. This trough is also so formed that it serves as a base and support for the machine. The treatment vessel is rotated at a speed necessary to generate the desired degree of centrifugal force by a pulley lla, belted to a pulley 11b upon a counter-shaft 11e, suitably supported below the floor of the mill. This counter-shaft is in turn driven by a pulley lld, belted to a source of power.

Within the treatment vessel is a deector or cylinder 16, of any suitable construction, whichY is supported by spiders 17 17 upon a shaft 18, passing axially through the vessel and having a bearing in an inwardly-projecting h'ub 19, secured to or integral with the head 10b, thus furnishing a lateral support for the'treatme'nt vessel at this end, and also in the hollow shaft 11 of this vessel. Sleeves 19a are mounted upon the inside of the head and upon the deflector-spiders, which, surrounding one another and the journals within the hubs 11 and 19, serve to protect them from dirt. The shaft 18 is also journaled in the support 12a of the treatment vessel and in a bearing 20, mounted upon a ball-andsocket or other Auniversal support held in a bracket 12, depending from the base of the machine, and at its extreme lower end in an antifriction step-bearin g 22. This step is preferably supported by pivoted links from a lever 23, fulcrumed on the bracket 21. The

opposite end of the lever contacts, through a suitable roll carried thereby, with a cam 24, continuously rotated by a slow-down Wormgearing 25, driven by a pulley 25, which is belted to a pulley 25b on the counter-shaft 11C. This cam mechanism effects a periodic longitudinal movement of the deflector within the vessel to permit and assist in the separation and discharge of material in a manner so well known that it will not be necessary to describe. The deiector is rotated ata different speed from the treatment vessel by a pulley 1S, belted to a pulley 18h on the countershaft.

In the base of the machine, surrounding a hub 26, extended downwardly from the stepplate l2 through an opening, are recesses 27, in which are seated spiral springs 28, pressing at one end against the hub 26 and being held in place by bosses 29 thereon and having their opposite ends resting upon movable heads or followers in the recesses. Against these heads bear screws 30, threaded through the ends of the recesses, serving to adjust the tension of the springs. Now, noting that the plate 12rL and the surface which supports it are curved upon the are of a circle the center of which lies at the center of the universal bearing 20 of the deflector-shaft and also that the pivoted support of the step 22 allows some lateral play, it will be seen that the treatment vessel and deflector are free to yield or sway transversely together in any direction, while being normally maintained in a vertical p0- sition by the pressure of the springs. Thus the vibration set up by the rotation of the two elements is absorbed. To equalize the beltpull upon the side of the vessel toward the counter-shaft, the spring on that side may be more compressed by its adj listing-screw than the others, or, as illustrated, a stronger spring, having greater resistance, may be used. It

will be furtherseen that the driving-gear of the separator is so arranged that the floor is free from the belts and shafting, resulting in economy of space and freedom from danger to persons passing among the machines.

As the process of the separation of material within machines of this character is familiar and as the elements more directly connected therewith form no part of this invention, no description of the operation will be given.
