    • 214,782. Smith, J. W. Feb. 27, 1923. Rolling discs.-In a process for rolling steel discs, such as those for vehicle wheels, a blank b which may be punched or cut from stock of uniform thickness is mounted on a rotary platen 1 with a surface 5 formed according to the taper required. The rolls 2 of conical form radiused at 4 into a narrow reducing section 3 of cylindrical form, are traversed axiallv outwards on guide bars 20 during rolling by a screw 25. The taper may be produced by feeding the rolls along a path inclined to the platen. The platen is provided with a ball bearing 10 and is adjusted to vary the thickness of the disc by an axially movable thrust bearing 11 with an indicator 15. In a modification the platen is replaced by conical rolls 30, Fig. 7, mounted in a housing 32 adjusted axially of the disc by a screwed and shouldered sleeve 34 that also forms a bearing for a central spindle 37 to which the blank is clamped at 40.
