separation of the dumpster 18 and chute 13 as the packer 17 applies pressure to force scrap into the dumpster the dumpster 18 is unlatched and removed when filled with another dumpster being repositioned the chute 13 packer 17 and dumpster 18 are arranged so that the scrap remains interior and shielded from the exterior environment a particularly unique feature of the disposal system 10 in fig1 is the connection of the chute 13 to the doorway 12 of the building the building 11 shown in fig1 is a brick or masonry construction and is chracteristic of commercial type buildings clearly if the dumpster 18 is jostled to any great degree as it is being positioned adjacent to the chute 13 any contact with the chute is transposed directly to the building 11 such shocks which often are relatively large would result in permanent damage to the masonry if the chute 13 were capable of direct contact with the building in order to eliminate or minimize any damage to the building the doorway 12 is purposely designed to be larger than the chute 13 since an object of this invention is to seal the interior of the building from the exterior environment the area between the doorway 12 and chute 13 must be closed an outer metal frame 12 constructed from material such as angle iron is secured to the doorway 12 of the building 11 as by bolting or another.
