Title: Ball race

Abstract: Two relatively movable bodies, such as a screw and a nut, engage each other through the intermediary of an endless row of balls guided in a closed guide path including a groove formed in a surface of one body confronting the other body. The guide path further includes at least one substantially prismatic bridge piece inserted in the grooved body and formed with an open-ended recess generally perpendicular to the groove, this recess communicating with one end of that groove and either with the opposite end of the same groove or with a corresponding end of a companion groove. The parallel end faces of the bridge piece are flush with opposite surfaces of the grooved body and, in the specific instances here described, are inclined with reference to the direction of the recess.
