PROVI- ROLLER-BEARING.

SPECIFICATION forming part of Letters Patent No. 698,351, dated April 22, 1902.

Application filed March 20, 1901.. Serial No. 51,999- (Il'omodel-l cation.

My invention is an improvement in rollerbearings specially designed for a thrustbear: ing; but the manner of holding in the rolls is capable of use in many different situations.

In the accompanying drawings, Figure 1 shows a face view of a thrust-bearing, and.

Fig. 2 is a sectional view of the same. Fig. 2 is an enlarged detail showing the end of the rollerand its containing-slotof Fig.2. Fig. 3 shows a modification. Fig. 3 is an enlarged detail of the roller and containing-slot of Fig. i

3. Fig.4 shows another modification. Fig. 5 shows a modified method of holding in the roll, and Fig. 6 shows a detail of construction.

In carrying out my invention I provide what I may term a cage in the form of a disk having an open center and a series of slots radiating from the open center. The Walls or faces of the disk taper inwardly toward the center, and the slots are also made tapering, their smaller ends being at their inner extremities, where they merge into the open center,and their broader ends being at their outer extremities. The disk is shown at A, the open center at B, and the radiating slots at C. To obviate the making the cage of tool-.

steel, a pin a, hardened and ground, is inserted at the head of each slot to form a hearing for the end of the roll.

The slots 0 are cut with straight walls, and the rollers b, which are tapering, are inserted, and in order to hold them in place I apply to each side of the cage alight sheet of metal, these sheets beingidentical in form with the cage, but having the slots therein of slightly less width, so that they overlap the slots in the cage sufficiently to hold the rolls in place and prevent their displacement. These sheets are indicated at D and are riveted or other- I make the cage A in two pieces and make the slots of varying widths, so that upon the outer face of the sections of thecage the width of the slots will be sufiicient to retain the rollers in place, While the width of the slots on the inner faces is sufiicient to allow the rollers to be inserted. The two sections are then placed one upon the other and riveted or otherwise secured, and this makes a self-con- V tained cage. 7

Instead, as in Figs.l to 3, of having the slots run through to the central opening I may make a stronger construction by having the slots intermediate of the cage between the inner opening and the outer periphery,as shown in Fig. 4:.

In Fig. 5 I show another modification, in

which the slot is first formed with straight walls by punching or otherwise, and thence upon each side of the slot and upon each face of the cage the metal is indented to force inwardl'y an overhanging lip, as shown at o,

which confines the roller in place.

What I claim is 1. A roller-bearingcomprising a cage having an intact outer periphery and an open center with a plurality of radiating slots opening into said center, rollers fitting in said slots, and means for confining the rollers in the slots, substantially as described. V

2.. A roller-bearing comprising a cage having radiating slots formed therein, rollers within said slots, said cage having independ-
