Abstract
Abstract A conveyor arrangement in which a rotatable circular platform is indexed with respect to the discharge locations of refuse compactors. A Y-shaped structure beneath the circular platform carries a plurality of wheels which support the platform while, at the same time, permitting rotational motion thereof with substantially small frictional resistance. A motor and geared speed-reduction unit supported by the Y-shaped structural frame is mechanically coupled to the platform. A closure arrangement, extending angularly along a portion of the angular path of the platform, rotates the base of a flexible container bag for the purpose of closing the bag at its neck after having been filled with compacted refuse.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
245 words
A conveyor arrangement comprising, in combination, a supporting stationary base frame; a rotatable member supported by said frame and rotatable about a predetermined axis through said rotatable member; drive means within said stationary base frame and linked to said rotatable member for rotating said member about said axis; at least one shaft member passing through an opening in said rotatable member for supporting at one end of said shaft member a container, said shaft member being spaced from said axis and on a radius of said rotatable member in proximity of the periphery of said rotary member; stationary rail means in the path of the other end of said shaft member when said rotatable member is rotated by said drive means, said rail means being mounted on said stationary base frame and beneath said rotatable member for bearing against said other end of said shaft member protruding from said rotatable member and rotating thereby said shaft member within said opening through said rotatable member; and a ring member secured to said rotatable member and suspended above said one end of said shaft member for suspending said container above said one end of said shaft member, whereby said container is held by said ring member substantially at the open end of said container and the closed bottom of said container is supported by said shaft member, said container being twisted closed when said shaft member is rotated within said opening upon rotation of said rotatable member.
Claim 2
Dependent Claim
245 words
A conveyor arrangement comprising, in combination, a supporting stationary base frame; a rotatable member supported by said frame and rotatable about a predetermined axis through said rotatable member; drive means within said stationary base frame and linked to said rotatable member for rotating said member about said axis; at least one shaft member passing through an opening in said rotatable member for supporting at one end of said shaft member a container, said shaft member being spaced from said axis and on a radius of said rotatable member in proximity of the periphery of said rotary member; stationary rail means in the path of the other end of said shaft member when said rotatable member is rotated by said drive means, said rail means being mounted on said stationary base frame and beneath said rotatable member for bearing against said other end of said shaft member protruding from said rotatable member and rotating thereby said shaft member within said opening through said rotatable member; and a ring member secured to said rotatable member and suspended above said one end of said shaft member for suspending said container above said one end of said shaft member, whereby said container is held by said ring member substantially at the open end of said container and the closed bottom of said container is supported by said shaft member, said container being twisted closed when said shaft member is rotated within said opening upon rotation of said rotatable member.
Claim 3
Dependent Claim
49 words
The conveyor arrangement as defined in claim 1 including a plurality of freely rotatable wheels mounted on said base frame and supporting said rotatable member so that said rotatable member is freely rotatable on said wheels, said wheels being angularly spaced about the angular path of said rotatable member.
Claim 4
Dependent Claim
28 words
The conveyor arrangement as defined in claim 1 wherein said stationary base frame comprises a Y-shaped structure supporting said rotatable member along three arms of said Y-shaped structure.
Claim 5
Dependent Claim
28 words
The conveyor arrangement as defined in claim 1 wherein said drive means comprises an electrical motor mounted on said stationary base frame in proximity of said predetermined axis.
Claim 6
Dependent Claim
38 words
The conveyor arrangement as defined in claim 4 including speed-reducing means mechanically coupled to said motor and linked to said rotatable member for driving said rotatable member at a speed lower than the output speed of said motor.
Claim 7
Dependent Claim
17 words
The conveyor arrangement as defined in claIm 1 wherein said rotatable member comprises a circular plate-shaped member.
Claim 8
Dependent Claim
27 words
The conveyor arrangement as defined in claim 1 including a flange member at said one end of said shaft member for supporting the bottom of said container.
Claim 9
Dependent Claim
37 words
The conveyor arrangement as defined in claim 1 including spring means urging said rail means against said other end of said shaft member; and spring-retaining means mounted on said space frame for supportedly retaining said spring means.
Claim 10
Dependent Claim
41 words
The conveyor arrangement as defined in claim 1 including first switching means mounted on said stationary base frame; and cam means on said rotatable member for actuating said first switch means when said shaft member is at a predetermined angular position.
Claim 11
Dependent Claim
40 words
The conveyor arrangement as defined in claim 1 including second switching means mounted on said stationary base frame; and auxiliary cam means for actuating said first and second switching means when said rotatable member has rotated through a complete revolution.
Claim 12
Dependent Claim
16 words
The conveyor arrangement as defined in claim 1 wherein said container comprises a flexible container bag.
