The peculiar construction of the brake employed in connection with the described cargear constitutes the subject-matter of another application for Letters Patent filed by me May 9, 1889, Serial No. 310,09i.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with the axle B, ring A, suspended from said axle, and the roller 0, riding on said ring and supporting the body, the tire T, encompassing said ring, substantially and for the purpose specified.

2. In combination with the axle B, car-bod y,

and roller 0, the ring A, formed of a bar of steel of circular shape joinedby overlapping interlocking ends, as and for the purpose set forth.

3. In combination with the axle B and bodysupporting roller O, the ring A, formed of a bar of steel of circular shape joined by overlapping interloeking ends welded together,

and the tire T, encompassing said ring, substantially as described and shown.

4. In combination with the roller O, the hollow journal D, provided with lateral channels r, and with a removable stopper on its end, substantially as described and shown.

5. In combination with the axle B, the check-plates K, provided with a perforation, and lubricant-chambers at the exteriors of said check-plates, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name this 7th day of February, 1889.
