BALLBEARING.

Lllidlltlti.

Application filed March 16, 1909.

To all whom it' may concern Be it known that l, MERRILL E. CLARK, a citizen of the VUnited States, residing' at Bradford, in the county of McKean and State of Pennsylvania, have invented a certain new and useful Improvement in Ball Bearings, of which the following is a specification, accompanied by drawings forming a part of the saine, in whichf Figure 1 represents a side view of a ball bearing embodying my present invention, partly shown in sectional view on the plane of the broken line 1-1, Fig. 3, by the removal of one quarter of the bearing. Fig. E2 is a top view ot' the bearingv with one quar ter removed. Fig. 3 is a transverse sectional view on the plane of the broken line 3 3, Fig. 2. Fig. l la transverse sectional view on the plane of the broken line e-fi, Fig. 1, and Fig. 5 is fi-detached View of a portion of the ball racc showing'the arrangement of the balls contained therein.

Similar reference let-ters and iig'ures refer to similar parts in the different views.

ll/ly present invention relates to a divided bearing or one in which the inclosin'g shell or ease is made in halves, and attached together by bolts or other suitable means, which enables the bearing to be divided and applied to or removed Jfrom a shaft, and it consists in the construction and arrangeinent of parts as hereinafter described and pointed out in the annexed claims.

Referring to the accompanying' drawings 1 denotes a rotating shaft inclosed in a ball bearingembodying my invention, comprising an outer shell 2 formed in halves and provided with lugs 3 to receive bolts a' by which the two halves are united. rll`he divided shell 2 is enlarged at its pp posite ends to provide space for two independent ball races, the race at one end being shown by the ltional views in Figs. 1, 2 and 3, but as t the opposite end. is a duplicate the i `iription ot one will suffice. lnclosed within the shell 2 is a sleeve 5 having its ends enlarged to forni a track 6 for the antilriction balls 7. The enlarged end of the shell is provided with a radial shonlder d against which rests an annular bearing plate or washer 9, preferably of steel, but divided in halves .to correspond with the aivision between the halves of the. shell 2. @p posingr the ball track 6 formed npon the enlarged end of the sleeve 5 is a ring 10 also Specification of Letters Yatent.

formed in halves and receiving the outward pressure ot' the balls. The outer edge of the ring 10 projects slightly over the end of the sleeve 5 and abuts against the outer edge of a plate 11, also formed in halves to correspend with the division of the shell 2, and v forming an inclosing wall for the outer end of the ball track, and having aclearance space 12 between the side o' the plate 11 and the enlarged end of the sleeve 5. The ends of the shell 2 are extended beyond the plate 11/ to receive a sheet metal dust cap 13, provided at its outer edge with a lange 14: which is attached to the ends of the shell il by screws 15. The space between the plates l) and 11 is less than the combined diameters ot the rows of balls inserted between them, which in the present instance are three in number, and in order to place the three rows between the plates 9 and 11 they are ar-- ranged in staggered relation to each other, with the center row of balls 16 overlapping the outer rows 17 and 18. The sleeve 5 diu vided to correspond with the division of the shell 2 is provided with lugs 19 to receive bolts 2() by which the halves of the sleeve are united, and within the sleeve 5 l place a bushing' 21 of some anti friction metal, such as gun metal or bronze, which forms a contact with the shaft 1. Between the late 11 and the dust cap 13 the space is lled with any suitable fibrous material 22, which is packedagainst the periphery of the shaft l in order to prevent the access of clust to the bearing` and the escape of lubricating niateri al.

ln operation, the bushing 21 and sleeve 5 rotate with the shaft, turning the anti-friction balls 'l' between the raceway 6 and the outer bearing ring 10, but if by accident the free movement of the sleeve 5 within the outer shell is impeded, might oCcuiLb the breakage of a ball, for example, the sha t 1 is free te rotate within the bushing 21 while the sleeve 5 is held stationary.

l claim,

1. The combination, with a. ro'tat shaft, of a luishing surrounding said shalt, a two part sleeve, havingr a peripheral ball track at each end, surroundings; and rotatable upon said bushing, an outer shell having in terior ball tracks corresponding to the tracks of said sleeve, a series of antifriction balls carried Within the races formed by said tracks and means for retaining said balls ble Til

2.- The combination, with e rotatable shaft, of a bushing surrounding said shaft,

a two part sleeve, having en enlarged section et each en@ "to form a, peripheral ball track,

vrotatable upon said bushing, an outer shell provided with enlarged recessed end portions to coperate with the ball tracks of seid sleeve to form bull reces`r :rplurality of :mtifriction balls carried within eneh ot soul bull races and means for retainingr said bulls within said races, seid retainingr means permitting endwise. movement of the sleeve 15 within said outer shell.
