  • Patent number: 5205224
    Abstract: A security drawer allowing articles to pass through an otherwise impervious wall, said drawer having operative doors limiting access to the inside operator as controlled by movement of the drawer. When the drawer access door is opened, an exterior delivery door is tightly closed. When the access door is placed in an intermediate position, the access door and exterior door are closed. When the access door is placed in a service position, the access door is placed into support structure chamber forming an absolute barrier between the inside operator and the outside public while opening the exterior door so as to allow the public access to articles such as fast food on the shelf of the drawer. The primary object of the invention is to protect the operator from robbery by strategic door placement in conjunction with drawer placement. The preferred embodiment of the device is constructed of scratch resistant ballistic acrylic.
