The sleeve or cone is then placed in position and the balls inserted through the opening in the portion 2 and the opening in the ring, and after the balls are all in place the screw isplaced in position and the parts are held against displacement, but tne ring and sleeve are free for movement.

In addition to the advantages hereinbefore specified the novel construction described possesses others which will be readily appreciated by'those skilled in the art, and while the structural embodiment of the invention as herein disclosed is what I at the present time consider preferable it is evident that the same is subject to changes, variations, modifications, and departure from the precise construction outlined. I therefore do not wish to be restricted to the details of construction before set forth, but reserve the right to make such changes, variations, and modifications as come properly within the scope of the protection prayed.

What is claimed as new is 1. A roller stand provided with a ballbearing mounted to automatically adjust said bearing embodying two concentric independently-movable members with a radial opening through one of said members and means for closing said radial opening.

2. A roller-stand provided with a universal roller and bearing mounted to automatically adjust itself with relation to said roller and embodying two concentric independentlymovable members one of which has a radial opening, and means movably mounted to close said opening.

3. The combination with the roller-stand, of a ring therein, a sleeve within the ring with a ball-race formed between the ring and sleeve, balls therein, and means for preventing displacement of the balls and allowing independent and universal movement of the ring and sleeve.

4. The combination with the roller-stand, of a ring therein, a sleeve within the ring, a ball-race being formed in the adjacent walls of the ring and sleeve, balls in said ball-race, and means entered from the stand and engaging the ring tohold the parts against displacement.

5. The combination with the roller-stand having an opening with rounded wall, of a ring therein with rounded outer face, a sleeve within the ring, balls interposed between the ring and sleeve, and means engaging the stand, the ring and the sleeve for securing the parts against displacement yet allowing universal movement.

6. The combination with the roller-stand having an opening, of a ring therein, a sleeve within the ring, interposed balls, and a screw engaged in an opening in the stand and in the ring and having a projection to prevent displacement of the balls.

In witness whereof I have hereunto set my .hand in the presence of two witnesses.
