Abstract
In a tire uniformity machine of the type wherein a loadwheel is received on a carriage slidably mounted on the machine frame for movement toward and away from the tire, the frame and the carriage are interconnected by mounting plates, one attached to the frame and one attached to the carriage, and interconnected by precision anti-friction flatway linear motion bearings of the type characterized by cross rollers or balls mounted in anti-friction gibs or ways so as to facilitate movement of the carriage and stability thereof in two axes to insure precise positioning of the loadwheel relatively of the tire. In a modified form of the invention, the carriage is T-shaped so that the top extended legs serve to support the bearing ways, engage the top of the bearings, and a gib or way is attached directly to the underside of the frame, thus eliminating the mounting plates while still insuring the facilitated movement of the carriage relatively of the frame.
