Pass through delivery device

A pass through closure for a prison cell that permits material to be safely passed to a person inside the cell, said closure comprising:

• a cell door having a first side, a second side and a slot therethrough;
• a container having first and second openings and being adapted for mounting on said first side of the cell door with the first opening communicating with the slot in said cell door;
• a first door mounted on said first side of said cell door for movement between a first position between the slot in said cell door and the first opening of said container and a second position permitting open communication between the cell door slot and the first opening of said container;
• a first latch for selectively maintaining said first door at the first position thereof, said first latch being positioned on said first side of said cell door to permit access thereto from only said first side of said cell door;
• a second door mounted at the second opening of said container for movement between an open position permitting access to the interior of said container and a closed position closing the second opening of said container;
• and
• a second latch for selectively maintaining said second door at the closed position, said second latch being positioned to permit access thereto from only said first side of said cell door, whereby said first and second doors can be accessed and operated only by an operator located on said first side of said cell door so that said first and second doors can be operated alternatively by the operator to pass material through the cell door slot without the operator being exposed to said second side of said cell door.

A kit for mounting a removable pass through delivery device on a partition having a slot therethrough that permits material to be safely passed though the slot in the partition, said kit comprising:

• a pair of track members adapted to be mounted on one side of the partition;
• a container having first and second openings and adapted to be mounted on said track members with the first opening communicating with the slot in the partition;
• a first door adapted to be mounted on said track members for movement between a first position between the partition slot and the first opening of said container and a second position permitting open communication between the partition slot and the first opening of said container;
• a first latch adapted to be mounted adjacent said first door for selectively maintaining said first door at the first position thereof, said first latch being positioned to permit access thereto from only one side of the partition when the removable pass through delivery device is mounted on the partition;
• a second door adapted to be mounted at the second opening of said container for movement between an open position permitting access to the interior of said container and a closed position closing the second opening of said container;
• and
• a second latch adapted to be mounted adjacent said second door for selectively maintaining said second door at the closed position, said second latch being positioned to permit access thereto from only one side of said partition when the removable pass through delivery device is mounted on the partition, whereby when the removable pass through delivery device is mounted on the partition said first and second doors can be operated alternatively by an operator located on one side of the partition to pass material through the partition slot without being exposed to the other side of the partition.

A method of safely passing material from a first side of a partition to a second side of the partition through a slot in the partition from said first side thereof, comprising the steps of:

• providing a container having first and second openings and first and second doors for selectively opening and closing the openings, respectively;
• positioning the container adjacent to and on said first side of the partition with the first opening located adjacent the slot in the partition;
• opening the second door while maintaining the first door in its closed position and placing material in the container through the second opening from said first side of the partition;
• and
• closing the second door and then opening the first door from a position on said first side of the partition to permit the material to be removed from the container through the first opening from said second side of the partition, whereby an operator located on said first side of the partition can pass the material from said first side of the partition to said second side thereof without both of the doors being opened at the same time and without the operator being exposed to said second side of the partition while passing material.
