Abstract:

A traveler assembly adapted to hold a line under tension while being movable on a track as on a sailing craft. The assembly comprises a main car section having parallel, spaced apart side portions and a connecting portion with apparatus to retain the line under tension. Fixed to the inner surface of each side portion is a generally oval shaped race filled with ball bearings specifically sized and positioned to be located close to but having some clearance with the surfaces of the track. At any lead angle of tension force applied to the main car section at least some of the ball bearings of either one or both races will contact and transmit the main tension forces to the track so that the traveler assembly can move along the track with a minimum of friction.
