ABSTRACT:
The present invention provides for a two tier gate device that is adapted to be removably secured to an existing mail sorting machine. The two tier gate device of the present invention includes a first gate and a second gate. The first gate is secured to the conventional mail sorting machine while the second tier is attached to the first tier so that the front end of the second gate is co-planar with the first tier while the second end of the second tier is off-set with the first tier. By providing for this design and configuration, the two tier gate device of the present invention will prevent flats, large letters, magazines, catalogs, or other various documents from turning sideways, rolling up, and to eventually jam the machine, while still enabling the pusher finer on the conventional machine to pass the gate device without interference.
