Description:
P. N. Pomeroy - patent attorney

This invention relates to anti-friction bearings and particularly to the grinding of the race-ways for the anti-friction members forming a part of the bearing assembly. The principal object of the invention is to provide means for securing the race member to be ground on a grinding machine in a manner so that the race member will have equal expansion or contraction over its entire area during the grinding operation. A further object is to provide attaching means for a race member to be ground whereby the race member can be ground on its inner or outer cylindrical faces, consecutively, or both faces may be ground simultaneously without distorting the race member. A further object is to provide lugs attached to the side face of a race member to be ground so that the inner and outer cylindrical faces of the ring are entirely exposed, the portions of the lugs to be attached to the grinding machine being spaced from the race member to permit the grinding of the full cylindrical inner and outer faces of the race member at one operation if desired.
