ABSTRACT:
An apparatus for transmitting force between a wheeled cart and an in-floor conveyor chain that includes a pin mounted on the cart which pivots out of engagement with the chain when a predetermined thrust is exceeded. A bumper connected to the pin via a resilient link assists the pin in retracting from engagement with the chain when the bumper strikes an obstacle in the path of the cart.
