Outdoors refuse-receiving system

In a sluice-like refuse-inserting means for attachment to the upper end of a chute forming part of a suction-operated refuse collecting system, said refuse-inserting means comprising a housing with an inserting opening and, on a lower level, a discharge opening adapted to communicate with the upper end of a chute, an adjustable element bounding a refuse receiving cavity, and means for adjusting said element alternatively in a position in which said cavity is accessible from the environment through said inserting opening and closed at said discharge opening and a position in which said cavity is inaccessible from the environment through said inserting opening and open at said discharge opening;

• the improvement wherein:
• said adjustable element includes a hollow cylindrical drum, means for rotating said drum approximately 90.degree. about a horizontal axis behind said inserting opening, said drum having opposed first and second openings through the peripheral surface of the drum, and wall means extending from the perimeter of said first opening to the perimeter of said second opening to delimit said cavity, said first drum opening being exposed behind the inserting opening in said housing in the one end position of drum rotation and said second drum opening being exposed in the discharge opening in said housing in the other end position of drum rotation for gravity discharge of refuse previously introduced into said cavity while simultaneously said first drum opening is exposed to the atmosphere in the interior of said housing;
• and said refuse inserting means further comprises a gasket extending around said discharge opening in a position sealingly to cooperate in said one end position of drum rotation with a portion of the drum wall intermediate said drum openings and in said other end position of drum rotation with a drum wall portion surrounding said second drum opening, and means resiliently supporting said drum in relation to opposed bearings fixed in said housing for permitting slight eccentric shift of said drum towards said gasket.

In a sluice-like refuse-inserting means for attachment to the upper end of a chute forming part of a suction-operated refuse collecting system, said refuse-inserting means comprising a housing having an inserting opening and, on a lower level, a discharge opening adapted to comunicate with the upper end of a chute, an adjustable element bounding a refuse receiving cavity, and means for adjusting said element alternatively in a position in which said cavity is accessible from the environment through said inserting opening and closed at said discharge opening and a position in which said cavity is inaccessible from the environment through said inserting opening and open at said discharge opening;

• the improvement wherein:
• said adjustable element includes a hollow cylindrical drum, means for rotating said drum approximately 90.degree. about a horizontal axis behind said inserting opening, said drum having opposed first and second openings through the peripheral surface of the drum, and well means extending from the perimeter of said first opening to the perimeter of said second opening to delimit said cavity, said first drum opening being exposed behind the inserting opening in said housing in the one end position of drum rotation and said second drum opening being exposed in the discharge opening in said housing in the other end position of drum rotation for gravity discharge of refuse previously introduced into said cavity while simultaneously said first drum opening is exposed to the atmosphere in the interior of said housing;
• and wherein said refuse inserting means further comprises:
• a tubular insert extending through the wall of the housing and bounding said inserting opening, said tubular insert at the inner end conforming to the periphery of said drum in a position corresponding to the position of said first drum opening in said one end position of drum rotation, said tubular insert at the outer end being provided with a door movable between insert closing and insert exposing positions;
• and locking means cooperating with wall portions of said drum to permit a shift of said door to the insert exposing position only in said one end position of drum rotation.
