Vehicle conveyor

In a conveyor having an endless chain for transporting a vehicle forwardly along a generally horizontal track, a roller mechanism for engaging a tire of the vehicle, the roller mechanism comprising:

• an arm having a first end hingedly secured to the chain and a second end remote from the first end;
• a first roller rotatably disposed on the arm near the second end;
• a second roller rotatably disposed on the arm intermediate the ends;
• and
• a third roller rotatably disposed on the arm near the first end;
• the arm being selectively positionable relative to the track so that the axes of rotation of the rollers are horizontal and perpendicular to the direction of travel of the chain along the conveyor and so that the axis of rotation of the first roller is higher than the axis of rotation of the second roller, the first roller being carried entirely above the track in position to engage the tire of the vehicle when the tire is located forwardly of the first roller on the track, the second roller being disposed forwardly relative to the first roller and in position to roll on the track to position the first roller to engage the tire only, the axis of rotation of the first roller being disposed a distance above the track greater than one-half the vertical distance from the track to the highest point on the circumference of the first roller, the third roller being disposed forwardly relative to the second roller and in position to engage the underside of the track when the roller mechanism is engaging the tire and transporting the vehicle.
