JOURNAL-BEARNG.

Specification of Letters Patent.

Patented J une 30, 1914.

Application filed 'May 29, 1913. Serial No. 770,699.

To all 'whom t may concern.'

Be it known that I, CLARANon H. CHARL- soN, a citizen of the United States, residing at Forest City, in the county of Winnebago and State of Iowa, have invented certain new and useful Improvements in Journal- Bearings, of which the following is a specication, reference being had to the accompanying drawings.

This invention relates to improvements in journals for cream separators or the like, and an object t-hereof is the provision of a journal in which friction is reduced to a minimum between the journal sleeve and the rotatable shaft supported therein.

Another object of this invention is the provision of a bearing in which the wear on the rotatable shaft supported therein is compensated for.

Still another object of this invention is the provision of a bearing comprising a sleeve having longitudinal slots therein, the slots carrying springs which project within the bore of the sleeve, the springs arranged on the sameside of the axial center of the shaft being disposed at right angles to each other.

With these and other objects in view, my invention consists in the novel construction, combination and arrangement of parts, to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which- Figure 1 is a vertical fragmentary section of' the neck of a cream separator or the like showing the journal connected thereto; Fig. 2 is a top plan view of the journal; Fig. 3 is a vertical section thereof; and Fig. lis a perspective view thereof.

Referring more particularly to the drawing, the numeral 5 designates a portion of the neck of a cream separator or other similar machine, the neck 5 having an inwardly extending flange 6 which is provided with a central annular bore 7.

The numeral 8 designates a journal sleeve provided with a reduced extension 9, the eX- tension 9 of the sleeve being adapted for engagement in the bore 7 of the flange. The inner wall of the flange is provided with a pair of diametrically opposite grooves 10, and secured to the lower edge of the extension 9 at diametrically opposite points are a pair of lugs l1 which project beyond the periphery of the extension for engagement in the grooves 10 when the extension is moved downwardly within the bore 7 of the iange. The length of the extension 9 is substantially the same as the thickness of the flange 6, so that when the shoulder 12 formed by the reduced extension 9 rests against the upper face of the flange 6, the lugs 11 are disposed immediately below the lower face of the flange 6 and it will be seen that by turning the sleeve, the same will be removably locked to the flange.

The sleeve 8 is adapted to receive an operating shaft 13, the bore of the sleeve being of relatively greater diameter than the diameter of the shaft. Formed in the body portion of the sleeve 8 are longitudinally extending slots 14 which terminate adjacent the shoulder 12, the slots 14- extending in tangential relation with the shaft 13. Spring plates 15 are adjustably arranged within the slots 11i to project within the bore of the sleeve, the plates being maintained in adjusted position by setscrews 16 which project through the wall of the sleeve into engagement with the plates. The plates disposed on one side of the longitudinal axis of the shaft 13 are arranged at right angles to each other, and the inner end of each plate 15 is provided on its inner face with a wearing block 17, the wearing blocks being adapted to engage the periphery of the shaft 13.

In the practical use of my device, the journal sleeve is mounted in the separator body as hereinbefore described, with the operating shaft 13 thereof projecting through the bore of the sleeve, and the wearing block 17 in engagement with the periphery of the shaft at. diametrically opposite points thereof. Owing to the resiliency of the plates 15, the wear of the shaft 13 will be readily compensated for, and the parallel springs may be adjusted by moving them outward, so as to allow them to be sprung wider apart, so that the wearing blocks will engage the periphery of shafts of greater diameters.

`What I claim is:

1. A device of the character described comprising a sleeve having a shaft rotatably mounted therein, said sleeve having longitudinal slots formed therein, spring plates endwise adjust-able through said slots and disposed in tangential relation with the shaft, and means` for maintaining said plates within said slots, as and for the purpose described.

2. A device of the character described comprising a sleeve having longitudinal slots formed therein, a shaft rotatably mounted in said sleeve, Springs adjustably arranged in said slots in tangential relation with the shaft, the inner surfaces of said springs being provided with wearing blocks fixed thereon for engagement with the periphery of said shaft, and means for maintaining said springs in adjusted postiton within said slots, as and for the purpose described.

3; In combina-tion with a body having an inwardly extending flange, the ange having an annular bore, of a sleeve having a reduced extension for engagement in the bore of the flange, a shaft rotatably mounted in said sleeve, said sleeve having longitudinal slots formed therein, inwardly proj eeting springs arranged in said slots in tangential relationl wit-h the shaft and wearing blocks formed:

Copies of this patent may be obtained for ve cents each, by addressing the Commissioner of' Patents,

on the inner ends of said springs for engagement with the periphery of the shaft, as and for the purpose described.

el. A device of the character described including a sleeve having' a shaft rotatably mounted therein, said sleeve being provided with slots therethrough, spring plates directed through said slots and disposed in tangential relation with the shaft, each of said plates being of Such a length as to have an end portion thereof extended exteriorly of the sleeve, and retaining means engagea-ble with the plate.

ln testimony whereof I hereunto aiiix my signature in the presenceof two witnesses.
