  • Patent number: 4245776
    Abstract: A pass-through drawer assembly is disclosed for transferring food and other commodities from an operator inside an enclosed area to a customer on the other side of the enclosure. The drawer assembly includes a drawer frame which is encased in a box-like housing having an opening covered by a hinged door on the operator's side and a pair of exterior hinged doors on the customer's side. A handle device is attached to the drawer frame so that the employee may horizontally extend and retract the drawer frame between the exterior doors to the customer. The drawer frame includes a bottom cam plate which has opposed camming slots, and the exterior doors have cam followers secured thereto that mate within the slots in such a manner that when the drawer frame is extended the exterior doors are progressively opened and when the drawer frame is retracted the doors are closed. The configuration of the camming slots and the position of the cam followers on the doors permit the doors to open less than 90.degree.
