BEARlNG FOR CENTRIFUGAL MACHINES.

SPECIFICATION forming part of Letters Patent N 0. 714,561, dated November 25, 1902.

Application filed June 19 1902. Serial No. 112,363. (No del.)

To all whom it may concern.-

Be it known that I, HARRY F. CLINE, a citizen of the United States, residing at Hutchinson, in the county of Reno, State of Kansas, have invented certain new and useful Improvements in Bearings for Centrifugal Ma chines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a bearing for centrifugal machines, and particularly to a structure adapted to support and permit the necessary vibration of the revolving basket or member of such machines.

The invention has for its object to provide a novel construction of bearing, whereby the supporting-shaft from the revolving member is mounted within a sleeve, which sleeve is further mounted for universal movement in an adjustable bearing-block.

A further object of the invention is to provide acushioning-block for permitting lateral oscillation of the shaft.

Other and further objects and ad vantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure l is a vertical section through a centrifugal machine having the invention applied thereto; Fig. 2, a horizontal section through the bearing at the base of the sleeve; Fig. 3, a vertical section through the lock-nut, and Fig. 4. an elevation of one of the bearing-blocks;

Like letters of reference refer to like parts in the several figures of the drawings.

In the drawings the letter A indicates a base of any desired construction or configuration, having standards A extending upward therefrom to support any suitable character of centrifugal machine for instance, a tank A ,havin g atits upper edge a removable drainflange A secured by set-screws, as shown. Within this tank a revolving perforated basket A of any ordinary construction is disposed' and provided atits lower portion with a driving-shaft B, which extends downward into a casing A carried by the upper face of the base A. This shaft 13 is provided at its lower part with a driving-pulley B, inclosing the casing A and keyed to the shaft in any suitable manner-for instance, by means of the set-key B and, if desired, by the additional set-screws B at opposite sides of the shaft. The driving'power forthe centrifugal machine is applied to this pulley B by any of the usual methods, and the pulley is also provided with an aperture B extending inwardly to the shaft B for the purpose of permitting oiling of the bearing for the shaft. This shaft B is disposed at its lower end within a sleeve 0, which is exteriorly threaded at its upper portion and provided at its lower portion with a ballor curved bearing 0, adapted to rest in suitable sockets D, formed in the bearing-blocks D, while the lower end of the shaft B rests upon a series of bearing-balls 0 located within the sleeve 0. The ball portion of the sleeve is also provided with oil-holes leading from the interior to the exterior thereof, so that theoil fed downward along the shaft B maypass through the ball portion 0 of the sleeve andlubricate the sockets D in the bearing-block. This bearing-block is formed in two or more parts for instance, as shown, where one end is provided with a tongue D adapted to fit into a corresponding recess D in the opposite block, and the blocks are adjusted toward each other to secure the proper bearing upon the sleeve by means of set-screws D threaded into the casing A carried by the base A.

Above the bearing-block D a cushion E, of rubber or other suitable material, is disposed within the casing A and rests upon a washer E, having a beveled aperture E therein. This cushioning-block is held under proper tension by means of the nut E threaded upon the exterior of the sleeve 0, while the nut E is locked in position by means of a lock-nut E, likewise threaded upon the sleeve 0 and providedupon its upper face with an oil-cup E adapted to receive the oil fed through the aperture B and permit the same to feed downward between the shaft 13 and the sleeve, thence through the sleeve to the sockets in the bearing-block, from which it may be drained through an opening A in the base and caught in any suitable receptacle.

In the operation of the invention it will be seen that a firm ball-bearing is provided for the shaft of the revolvingmember and the oscillation of this shaft permitted by means of the sleeve having a universal movement in the bearing-block, while the cushion above the sleeve prevents any shocks and equalizes the vibration. The lock-nut provided with the oil-cup upon its upper surface also insures a continued lubrication of the parts, which is further assisted by means of the apertures in the ball portion of the sleeve, while the interlocking members of the bearingblock permit the same to be adjusted so as to form a proper bearing for the sleeve and to be held at such adjustment, which is highly essential in high-speed machinery of this character, wherein a firm and easy-running bearing must be secured in order to obtain high speed at a minimum expenditure of power.

It will be obvious that changes may be made in the details of construction and configuration of the invention without departing from the spirit thereof as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-- 1. A bearing for centrifugal machines comprising a base having a bearing-block thereon, a sleeve mounted in said block for universal movement, a rotating shaft disposed within said sleeve, a cushioning-block above said bearing-block, and a compressing-nut for said cushion threaded upon said sleeve;

substantially as specified.

2. A bearing for centrifugal machines comprising a base having a bearing-block thereon, a sleeve mounted in said block for uni-,

versal movement, a rotating shaft disposed within said sleeve, a cushioning-block above said bearing-block, a compressing-nut for said cushion threaded upon said sleeve, ballbearings between said sleeve and the lower end of said shaft, and a lock-nut above said compressing-nut having an oil-cup upon its upper face; substantially as specified.

3. A bearing for centrifugal machines comprising a base having a bearing-block there on, a sleeve mounted in said block for universal movement, a rotating shaft disposed within said sleeve, a cushioning-block above said bearing-block, a compressing-nut for said cushion threaded upon said sleeve, ballbearings between said sleeve and the lower end of said shaft, a lock-nut above said compressing-nut having an oil-cup upon its upper face, a driving-pulley provided with an opening leading to said oil-cup and keyed to said shaft to inclose said bearing, and means carried by said pulley to hold said key in position; substantially as specified.

4. A bearing for centrifugal machines comprising a base having a casing thereon, a divided bearing-block located at the base of said casing, means carried by the casing for adj usting the parts of said block toward each other, a sleeve having a ball portion at its lower end seated within sockets in said blocks and provided with an oil-opening through said ball portion, a rubber block disposed upon said bearing-block, and a compressing-nut carried by said sleeve and bearing upon said rubber block; substantially as specified.

5. A bearing for centrifugal machines comprising a base having a casing thereon, adivided bearing-block located at the base of said casing, means carried by the casing for adj usting the parts of said block toward each other,
