Definitions

  • ABSTRACT An improved garbage disposal system for multi-story high rise apartment buildings and the like comprising a vertically disposed branch conduit extending through substantially the height of the building and dependently connected to a main conveying conduit for delivery of garbage thereto for transport to a remote location and a plurality of vertical garbage disposal chutes of limited extend each selectively serving a plurality of floors and including a selectively operable valve assembly at the dependent end thereof for effecting temporary accumulation of garbage therein and the selectively induced release and introduction thereof into the branch conduit.
  • the present invention relates to an improved system for pneumatic conveyance and disposal of household garbage and similar materials from tall, multi-story apartment houses of the so-called high rise type.
  • every garbage receiving port is connected to a common duct for conveyance of garbage by a negative pressure to a collection station or destructing plant.
  • each building is connected to a main suction conduit via a main building conduit to which the lower end of the vertically disposed common garbage receiving chute is connected via a periodically operating valve.
  • the present invention is directed to the elimination of the above disadvantages and, accordingly, is directed to an improved arrangement or system for the conveyance of garbage from a tall multi-story or high rise type-apartment building through a single branch conduit running through and from said building to a remotely located underground main conveying conduit and which, in its broader aspects, includes an elongate, common, vertically disposed branch conduit that extends upwardly through at least a major portion of the height of the building and a plurality of vertically disposed garbage disposal chutes of limited vertical extent each terminally connected to said branch conduit and selectively associated with one height section of the building comprising a plurality but limited number of floors thereof and each such chute including a valve assembly that serves to collect'the garbage introduced therein and to intermittently release the same into said It should be understood that while this invention may be incorporated in any relatively tall multi-story building, it is particularly suited for use in buildings comprising more than 20 floors.
  • a branch conduit 10 dependently connected to a remotely located underground main suction conduit includes a vertically disposed portion that extends upwardly through the entire height of the building.
  • a branch conduit 10 is provided with air admission means, generally designated 11, that may be valve operated.
  • each chute 12 includes 5 to 10 discrete garbage disposal openings depending on the calculated amount of garbage, anticipated per floor or the like.
  • the disposal chutes are provided with a selectively actuatable and normally closed valve assembly 14 on which the garbage introduced into the respective chutes 12 is temporarily accumulated.
  • the system operates in the following way:
  • the garbage accumulated in disposal chutes 12 subsequent to introduction through the ports 13 is discharged individually into the branch conduit 10 at predeterminable intervals as determined either by a time control system or by some kind of feeler device when a certain amount of garbage has been collected at the valve causing the valve assembly 14 to be actuated and to permit the collected garbage in the particular chute to be discharged into and down through the branch conduit 10 and into the main conveying conduit for delivery to the collecting station.
  • the lower portion of each disposal chute 12 will thus act as a preliminary accumulating or collecting location for the garbage introduced through the disposal ports 13.
  • the branch conduit 10 may be of comparatively small cross-sectional extent, which permits a reduction in the construction cost. It
  • branch conduits in a way most suitable from the point of view of both building construction and operation and independently of the position of the disposal openings which is highly advantageous from many points of view.
  • each disposal chute 12 may desirably slightly overlap each other so that the valve at the lower end of one chute 12 will be positioned somewhat below the uppermost disposal opening 13 of the chute 12 serving the adjacently lower group of floors.
  • each chute 12 may be vented either directly out to the facade of the building or to a common valve conduit leading from all of the chutes up to the roof.
  • a vertically disposed common branch conduit extending upwardly through at least a major portion of the height of said building and dependently connected to a main conveying conduit for delivery of garbage thereto for transport to a remote location
  • each chute extending over at least several floors in height and adapted to selectively serve a plurality of particular floors of said building and each dependently interconnected with said branch conduit, said interconnections being vertically spaced from each other and located along a substantial portion of the length thereof,
  • each of said chutes including at least one garbage disposal port on each of the particular floors being serviced by said chute for receiving garbage therefrom,
  • branch conduit includes an air admission valve at the upper terminus thereof.
  • a system as set forth in claim 1 including means for maintaining at least a subatmospheric pressure of minimal predetermined magnitude within said branch conduit and said chutes intermediate periods of pneumatically induced garbage displacement therewithin.
