ADJUSTABLE J OURNAL BOX.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed January 16, 1909. Serial No. 472,762.

To all whom it may concern:

Be it known that I, FRANCIS E. BUx'roN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Adjustable J ournal-Boxes in addition to that secured to me by Letters Patent of the United States extreme ends of the bearing sleeve and rotatable therewith, and an intermediate sleeve positioned around the said bearing sleeve, havin its inner central portion engaging a threa ed portion of the bearingsleeve, and independently rotatable therewith within a fixed casing.

The objects of my invention are: first, to

- provide a wear-compensating box for small journals; second to provide a box constructed in a manner to dispense with oilwastes that are so destructive to manufacturing plants. I attain these objects by the mechanism illustrated in the accompanying drawings in which-- Figures 1 and 2 illustrate the complete box, being an elevation of the front end, and a side elevation of the box partly in section; the lower parts broken away showing the general arrangement. Fig. 3 is a section through the case and sleeve, in part taken on line wm referring to Fig. 4, having the upper part of the sleeve broken away. Fig. 4c is a front end elevation of the box, the front supporting collar and journal being removed to show the bearing sleeve mechanism. Fig. 5 is an end elevation of front supporting collar, the parts be ing in section to illustrate the inclosed sectional oil ring mechanism. Fig. 6 is an enlarged perspective view of the eccentric oll ring and wedge adjustment, for retaining the oil. Fig. 7 is an inner end elevation of the front supporting spanner collar, illustrating the spacing lug supports. Fig. 8 is a longitudinal section through the outer case and the engaging collars, the bearing sleeve proper being removed. Fig. 9 is a side elevation of the bearing slceveunit, showing its illustrate the screw lock and position and a sectional view of the surrounding compression sleeve. Fig. 10 is an end elevation of the rear supporting collar,

illustrating the triangular supporting lugs. Fig. 11, is a sectional view of the box complete taken on the line y-y referring to Flg. 3, showing the practically quartered effect of the bearing sleeve part. Figs. 12 and 13, are enlarged views, being side and end elevations of the front supporting collar and outer case, having parts broken away to the oil ring adjustment of the same. Fig. 14, is an enlarged view of the front spanner supporting collar as it appears looking at the top, having the side parts broken away and shownin section, illustrating the oil ring segments, the wedge and the screw adjustment. Fig. 15 is a side elevation of the box, inclosed in a reversible outer casing slightly modified 1n form. Figs. 16 and 17 are views showing the front and rear elevation, respectively, of the construction shown in Fig. 15, to illustrate the spanner collar and the blank rear cap. Fig. 18 is avertical plan of the box complete. And Fig. 19 is a view showing the preferred form of the front supporting spanner collar with the spanner-wrench applied.

Similar letters refer to similar figures throughout the several views.

In the accompanying drawings A represents an outer cylindrical casing; midway between its ends and positioned vertically over said casing is an opening having threads formed therein to receive a locking screw, a that will be explained presently; at the base of the casing are placed ribs, (1, that rigidly secure the casing to the main frame. Near the front end of the casing A is provided a number of adjusting taper studs wa', the office of which will be mentioned presently, and formed central and parallel through the fixed casing is an aperture much larger than the journal to be carried.

B is a cylindrical sleeve, there being formed on its periphery and midway between its ends a number of equidistant slots B to receive the locking screw a to prevent its rotation, forward and backward within the outer casing A.

Formed centrally within the sleeve B, is provided a round opening as indicated having longitudinally convergent walls on which are formed equidistant from the ends a threaded portion to engage the inner hearing sleeve element presently referred to. In the annular conical space between the said sleeve opening and the journal G, is placed a unitary arrangement of bearing sleeve supports O, formed separate on their exterior conical portions within the sleeve B, but being joined compressibly and expansively together by a suitable, bearing lining at f, sub stantially as shown the drawings.-

The bearing sleeve element O, is stationary relative to itslongitudinal action and practically extends through the full length of the casing, said bearing sleeve O is reduced at its back end to engage substantially within the sleeve B, and of a proper form to allow it to extend a proper distance beyond the front end of the sleeve B, which will be referred to later.

On the periphery of the bearing sleeve O, in the attached drawings, is formed flaring longitudinal grooves 0 their side margins converging practically together and extending the full length of the bearing sleeve 0. Said grooves are ninety degrees apart. and formed on lines running parallel with the axis of the journal G. Clearance slots f are formed at the base of the said grooves, that extend inward to the surface of the journal G, they being the means provided for lubrication.

On the periphery of the bearing sleeve and a proper distance between its ends are formed threads 0 that engage with corresponding threads 6, within the sleeve B. The extreme ends of the bearing-sleeve C, are supported by flanged collars E and D, formed to fit within the casing A in their relative positions and gfree to rotate therein. A groove 2 is provided on the reduced diameters of the collars E and D and at the base of the same is provided a plurality of perforations e that receive the locking studs aa, referring to Figs. 5 and12, substantially locking the collar E after the bearing sleeve O has been adjusted. On the inner surface of the supporting collars E and D, are provided triangular lugs eand D extending inward and of a proper form to register and interlock with the bearing sleeve C, being the means for the said bearing sleeve to be rotated by the collar E, by applying the spanner K.

Provided in the shaft openings of the collars E and D, are eccentric grooves to receive sectional oil rings E, e, and e of like form and preferably made of fiber, the central 0 eni'ng of the oil ring ee being concentric with the journal G the larger ends of the oil ring seg ments ee are alike and are provided with alining grooves e registering as indicated with the tongues E of like form provided on wedge E. The reduced ends ea -e" of the segments ee are formed to overla slightly at an angle to facilitate their applitions cation and adjustment. It should be evident that the said fiber segments ee after a period of service will become slightly worn by reason of their close engagement with the journal G. Then sufficient fiber may be removed at ee and adjusted again by the screw 6 preventing the escape of the oil. The segmental oil ring ee in the collar D, is substantially the same in action, and the adjustment is provided through the opening in the casing A at a.

By the above description and the accompanying drawings it should be evident that l have provided means whereby the journal and the relative parts of the box are completely lubricated, the box working equally as well when placed in a vertical position. Inthe foregoing description I wish to make plain that the preferably gray iron hearing sleeve 0, is not designed to be dependable as a unit in action, but it is formed into a plurality of lobes spaced apart and held conjunctively together by its lining at f there being slots and intermediate perforaformed at the base of the flaring grooves, employed for the reason before stated. More specifically stated, the said bearing sleeve C, after being assembled within the casing A, is supported at its extreme ends by the collars E and D, interlocking within the groove 0 and supported intermediately by the sleeve B. I It is obvious that when releasing the locking screws a-a and turning the spanner collar E, the bearing sleeve C and the collar D will be caiised to rotate, equally compressing the bearing sleeve C radially toward the journal G, by reason of its angular threaded portion engaging within the sleeve B, while a reverse motion of the collar E will cause the sleeve B to travel longitudinally backward, allowing the bearing sleeve C, to extend normally. It is also evident that, by releasing the screw lock a and turning the collar E with spanner wrench K as before, rotation of the complete inner box as a unit is provided thereby bringingthe less worn surface of the bearing. sleeve into action independent of its radial adjustment.

In practice to assemble my improved box, I proceed in the following manner: The outer casing being in position I- first place the collar D, at the back end of the casing; I then place the sleeve B, in its position within the casing A, and screw down the look a to fit into the slot B- The sleeve B being held securely, I then enter the reduced end of the bearing sleeve C, within the conical aperture of sleeve B. I now turn the said bearing sleeve C, until it registers at a point previously indicated, being now in threaded contact within the sleeve B. I now place the collar E in its position interlocking it with the bearing sleeve as indicated. I now adjust the screws wa-,and the com- In Figs. 15, 16, 17, and 18, I have shown a slightly modified form; the casing H is provided with a removable cap H; the bearing sleeve proper can be reversed end to end, for reasons not necessary to mention. Collar J is designed for the spanner adjust ment to economize space; the end cap J being blank requires no oil ring; in other resp'ects-the modified form is substantially the same as the preferred construction.

Having shown and described the construction, and given the best means known to me for the operation of y journal-box, I desire it to be understood that various interchanges may be made in the manner of assembling, in accordance with the varied requirements of service to be performed, without departing from or sacrificing any of the advantages thereof.
