A disposal chute for waste paper, cardboard, and other packing materials is disclosed which is intended to temporarily connect a container to a building. The disposal chute is permanently positioned adjacent to the building. A slip joint construction connects the chute to the building in such a manner as to completely enclose the mating surfaces while allowing relative movement between the chute and the building. The mating surface at the building is designed so that the relative movement does not adversely affect the brick and mortar construction of the building surrounding the opening for the chute. A container, which may be removed and replaced relatively often, is positioned adjacent to the chute to be in communication with the building. The placing and removing of the container results in the relative movement between the chute and the building.
In a system for collection of waste materials including a container having a truck engaging means for removing, replacing and emptying the container, said container having an opening, a building having an opening, a chute, and support means for said chute positioned in spaced relation to said building, said building and said support supporting said chute in such a way as to allow slight axial movement of said chute during removal and replacement of said container, an improvement comprising said chute having a first open end, said opening of said container connected to said first open end of said chute, said chute having a second open end substantially smaller than said building opening, said second open end of said chute and said building opening arranged in spaced apart relationship, and seal means enclosing said building opening to said second open end of said chute, said seal means having slip joint means allowing said axial relative movement between said chute and said building opening.
In a system for collecting waste materials, temporary storage and elimination, the combination of a container including truck engaging means for removing, replacing and emptying the container, said container having an opening, a building with an opening, a chute with first and second openings, support means for said chute positioned in spaced relation to said building opening, said building and said support supporting said chute in such a way as to allow slight axial movement of said chute during removal and replacement of said container, means connecting the first opening of said chute and the opening in said container, said second opening of said chute and said building opening arranged in spaced apart relationship, and seal means connecting said second opening of said chute to said building opening, said seal means including compression means whereby axially relative movement between said chute and said building is absorbed by said compression means without damage to said building.
An apparatus for permanently sealing a building entrance to a trash container having truck engaging means for removing, replacing and emptying said container, comprising a chute with first and second openings, support means for said chute positioned in spaced relation to said building, said building and said support supporting said chute in such a way as to allow slight axial movement of said chute during removal and replacement of said container, said first opening of said chute adapted for access to said trash container, said second opening of said chute positioned within said building entrance, said second opening of said chute and said building entrance arranged in spaced apart relationship, sealing means positioned between said building entrance and said second opening of said chute, first joint means affixed to said second opening of said chute, and second joint means affixed to said sealing means, said first and second joint means interconnected to absorb relative movement between said chute and said building.
