BALL-BEARING'.

Application filed December 17, 1910. Serial No. 597,237.84.

Bearings, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to ball bearings, and more particularlyto that class thereof provided with continuous or uninterrupted' tracks or ways, which offer no impediment or obstruction tothe travel of the balls therein, and whereby the several parts are held in assembled' relations, thusconsti/tu/ting a bearing of the unit-handling type.

The present improvement contemplates the formation thereof with certain additional features which facilitate assemblageand also possess other advantages as will hereafter appear.

Bearings of the unit-handling type and provided withl uninterrupted Ytracks areassembled in various ways, among which may be mentioned the employmgnigf eccentric displacement according to the well-known Conrad invention. The last-mentioned procedure, namely eccentric displacement, vis ordinarily followed for the introduction of substantially less than the full .complement of balls, after which, if additional ones. are desired, they may be inserted by other means, such as non-full-depth filling openings, and the'like.y My present invention, however, contemplates the complete assemblage at one time, and this even in the case of full type bearings, wherein the raceway is entirely or almost filled with balls.-

To this end I provide on at least one of the rings at the side of the track or way, an outwardly inclined.V onvtapered. surface, which facilitates the Y assembled position yover the balls when located in the track or way of the other ring. Specifically, this inclined surface extends throughout-the periphery of the ring, so that it may be placed in its final position by forcing or pressure overan entire complement of-balls located in the other ring. Moreover in the'specic form illustrated, the inclined surface is so located' as to constitute a track or way for one of the series of balls. In this way, the `inclined surface subserves a double function, in'that it not Specification of Letters Patent.

only facilitates the assemblage of the bearing, but also serversy as a track or way when the parts are in assembled relation.A

In the accompanying drawings I have shown several modifications of the general idea by way ofeXample, and obviously7 many changes and variations may be made therein without departing from the spirit of the invention; and generally speaking, I do not desire to limit myself to any specific form or embodiment, eX-ce )t in so far as such limitations are specified in the claims.

Referring to the drawings: Figure l, is a side view of a bearing embodying my invention; and F ig. 2 is a transverse section thereof. The bearing consists of an outer ring A5 and an inner ring B5, the latter being formed with two continuous and uninterrupted grooved tracks or ways b5 and Z55, adapted to receive the two series of balls and C5. The outer ring A5 is formed with a grooved track or way a5 adapted t0 .engage the series of balls C5, and at one side thereof is provided with an inclined surface E5, intersecting the track or way a5 on a-line above the central or lowest line thereof, thus constituting a rib D5, at one side of the balls C5, whereby the parts are held in proper operative relations after they are assembled. The inclined or tapered surface E5 extends entirely around the ring A5 or-throughout its periphery:

The method of assemblage is as follows: The balls C55 and C5 are first placed in their respective tracks or ways of the ring B5. The ming A5 is then brought into relation with the balls by placing the inclined or tapered surface E5 in Contact with the series of balls C5. The ring is then pressed orv forced into its final position, which opera- OIl llfacilitatedby/ the surface E5, as" it "prmit'sts'easy movement over the balls C5,

the central line of the grooved track or way, than is possible in connection with the bottom. of a non-full-depth lling opening, through which the balls are forced or pressed oneat a time. Not only does this result in reducing the liabilityT of the balls to escape, but in addition greater. resistance to side pressure is thereby'aorded. lt will be further noted that the inclined surface E5 serves Aalso as a` track or way in connection with the series of balls CGQ n other lwords when the parts are assembled, the rnceway for the balls C" is constituted by the Agrooved track or way b in the ring B5, and by the inclined or tapered surface E5 of the ring A, it being noted that this raceway is angularly located -so that the balls C may take both radial and end load, in the same manner for instance as the correspondin1r series Aof balls shown in my pre- -vious Letters Patent No. 1,059,538. An-

other advantage arisingfrom this particular form is involved in the fact that, due to the mode of assemblage described, am enabled to dispense with thel lling opening -as shown in such Letters Patent.

The above described embodiments of my invention are presented here merely by way of example, and as before stated Amany equivalent forms and variationsl will suggest themselves to those skilled in the art andstill be embodied within the spiritV of my invention.

Having thus described my invention, its

construction and mode of operation, what claim and desire to secure by Letters Patent I of the'United States is as follows:

1. In a ball bearing, the combination of the inner and outer rings and a plurality of series of bal-ls mounted therebetween, one of said rings being formed with a continib ous and uninterrupted track `or way to enuninterrupted tracks or ways, and the other ring` being formed with one continuous or uninterrupted track or Way and further provided at one side .ofthe track-or way with an outwardly inclined or tapered surface of such form as lto allow 'the forcing of the ring over the. rst 'series of'balls when located in the other ring, and also toserve as a track orway 'for the second series of balls.

in testimonyy whereof I have afixed by signature in presence'of two witnesses.
