Total Claims: 6
Claim 1
Independent Claim
221 words
A vehicle conveyor for engagement with the tire of a vehicle to push the vehicle along a guided path, comprising a floor, a track supported by said floor and having a planar upper surface to receive the support the tire, means defining a space along the side edges of said track, endless chain means in each of said spaces, said chain means including opposed spaced lugs, a plurality of shafts supported at their opposite ends by said opposed lugs, each of said shafts rotatably supporting a pusher roller at an elevation above said track which is greater than the radius of said roller, wheels on said shaft in rolling contact with said upper surface of said track, each of said wheels including a hub portion and a flange having a diameter greater than the diameter of said hub portion to extend beyond the edge of said track, said flanges being in rolling contact with the side edge portions of said track to maintain said pusher rollers in vertical alignment with said track, at least one of said opposed lugs having a notch for receiving one end of said shaft, and retention means for retaining said shaft in said notch and releasing said shaft upon application of a predetermined overload for said shaft in a direction toward the opening of said notch.
