ABSTRACT:
A security transfer unit has a cashier's door and a customer's door for providing access to an intermediate transfer chamber from opposite sides of a security screen. Only one of the doors can be opened to give access to the chamber at a time, opening of the cashier's door being normally obstructed by a pivotted bar that is swung down across the door to engage a bracket. Swinging of the bar up to remove the obstruction turns a shaft to block, via a cam, withdrawal of catch-bolts which hold the customer's door closed. The cam in this condition also abuts a block mounted on the rear edge of the door such that if the customer's door is open as the bar is swung up it will be forced closed before the cashier's door can be opened.
