ROLLER-BEARING.

SPECIFICATION forming part of Letters :Patent No. 584,893, dated June 22, 1897.

Application filed August 14, 1896.

T0 LLZZ whom t nca/,y concern,.-

Be it known that I, THOMAS J. REID, a citizen of the United States, residing at Washington Court-House, in the county of Fayette and State of Ohio, have inventeda certain new and useful Improvement in Roller-Bearings, of which the following is a specification.

My invention relates to antifrictional 4journal-bearings; and the objects of my invention are to provide a combined ball and roller bearing of such improved construction and arrangement of parts as to provide a uniform wear of both balls and rollers, to provide means for adjustment of the rollers and balls, sleeves and casings, to reduce the frictional contact between the rollers, to prevent undue lateral movement of said rollers and consequent wear of the parts, and to produce other improvements, the details of construction of which Will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a central vertical section of a journal-box having my improvements'therein. Fig. 2 is a transverse section on line x00 of Fig. l. Fig. 3 is a detail view showing two adjacent rollers and their end balls, said rollers being shown in longitudinal section and Fig. 4 is a partial longitudinal section of a j ournal-box, showing a modilied construction and arrangement of the bearings.

Similar letters refer to similar parts throughout the several views.

d represents the box or external case, which is provided on its inner end with the inturned flange portion a. On the inner side of the box d I fit an inner casing which, as indicated in the drawings, is formed of separated sections 01,2 a3, the inner surfaces of these sections tapering toward their inner ends. The outer end of each of these casing-sections has a threaded connection with a cone-bearin g ring b.

c and c represent the axle-spindle sleevesections, which, as prescribed for the inner casing-sections, are separated centrally and have their outer surfaces inclined or tapered toward their inner ends. The inner end of the section c has a threaded connection with an inner cone-bearing ring c2, which forms an inner end extension of the sleeve-section c.

Serial No. 602,725. (No model.)

The outer end of the sleeve-section c has a threaded connection with a sleeve-head or end cap d, the latter being opposite the bearingring b and having formed in its periphery a cone-bearing surface d.

d2 represent parallel rollers, the latter being arranged between the casing-sections and sleeve-sections and having their exterior surfaces tapering toward their outer ends to conform substantially to the inclines or tapers of said casin g sleeve-sections.

e represent bearing-balls, these balls being arranged in inner and outer rings and one of said balls bearing partially in each end of each of the rollers and partiallyin the sleeve- .cap d, casing extensions b, and ring c2.

j' represents a packing-ring, of felt or similar material, which is arranged in a recess formed partially in the end of the casing-ring b and sleeve-ring c2. On the outer side of this packing-ring I provide a follower f.

g represents the outer end cap of the boxing, which, by means of screws g', is united to said external boxing.

g2 represent set-screws which pass through threaded openings in the cap g and have their inner ends in contact with the casing-ring b. This cap is provided with a central adjusting and end-thrust-receiving screw h, the latter having formed in its inner end a threaded socket which receives a screw h. About the inner end portion of this screw is arranged a bearing-ring h2, and between said bearingring and the screw h I provide a cone-bearing block or ring h3. Between the ring h3 and ring h2 are interposed bearing-balls h4.

As shown in the drawings, the inner surface of the ring h2 is designed to be in contact with the outer end surface of the sleeve cap or head d..

i represents an axle-spindle which is surrounded by the sleeve-sections c and c and which is laterally movable therein.

In operation it is evident that the rotation of the axle-spindle will carry with it the sleevesections c c', sleeve-cap section d, and inner cone-bearing c2, while the external casing or box and its inner casing-sections a2 CL3 and cone-bearing ring b will remain stationary. It will be noted that the balls e are arranged partially in rings I) b and partially against parts c2 d about the inner and outer sleeve- IOO sections, and that these balls are of such relative size with the central portions of the tubular rollers as to result, as indicated in Fig. 3 of the drawings, in a comparatively light touch of the balls of each circle or ring. In this manner it is obvious that not only the rollers but the balls themselves will loere-V tained at all times in parallel alinement with each other and that no frictional contact Will exist between the roller-bodies. It will thus be seen that the friction between the bearing parts of my device will be exceedingly slight.

By employing a ball, as herein shown and described, at each end of each of the. roller-l bodies it will be observed that each pair of oppositely-located balls practically become a Part of the lollel,` rnieb they ndion.-

From the. construction which I hlaYe shown and described it isobyions that adjnstlnent of the balls or the partswithin which they bear for the pinpose of compensating for Wear on said balls or parts may be accomplished by pro-per rotation of the ndinStng-senewn o? and end-tnrust-receiving screw In It Will bel observed tbet the pntsof my improved journal-,boxare` few, Sllnpleof con.- strnction, and positive in operation, and that the Saule may be produced at a reasonable cost of mannfactnre.

As indicated in Fig. d ofthe drawings., l may modify tl'iey construction1 liereinbetoreA de: Senibed by the oonntrnetion of each of. the rollers in two separated sections, which are indiodted at 7e, end 7e', and by the employment of4 a central or third ring; of balls 75,2, 'which fne nlndneed between end hevether periph: i

in connection with said roller-sections additional means are provided for retaining the i rollers in alinement.

, what l claim, and desire to secure by Letters Patent, is-
