## Abstract

Apparatus for covering a large land area with a long length, wide width heavy flexible sheeting comprising: a main framework adapted for mounting onto the end of a crowd of an excavator; a swivel assembly rotatably secured to the main framework; an elongated support member secured to the swivel assembly; a bearing assembly pivotably fixed to one end of the support member; a bushing assembly pivotably mounted to the other end of the support member; an arbor assembly including an elongated mandrel for receiving and supporting a roll of sheeting with one end of the mandrel journalled at one of its ends in the bushing assembly and the opposite end removably arranged in the bearing assembly.

## Claims

### Claim 1

Apparatus for covering a large land area with wide width, flexible sheeting, comprising:
an elongated rotatable framework adapted for mounting engagement into the end of a movable work arm of a powered construction vehicle, and including an elongated support member;
a downwardly extending bushing assembly supported at one end section of said support member and having a pivotable free lower end section;
a downwardly extending elongated bearing arm assembly pivotably secured to the other end section of said support member;
an arbor assembly including an elongated mandrel sized and shaped for receiving and supporting a roll of sheeting and having one end thereof journalled in said pivotable lower end of said bushing assembly and its opposite other end removably received in a lower end section of said bearing arm assembly; and
wherein when said bearing arm assembly is pivoted away from said other end section of said support member, said mandrel is released from said bearing arm assembly and is pivoted downwardly and when said bearing arm assembly is pivoted toward said other end section of said support member, said other end of said mandrel is received in said lower end section of said bearing arm assembly.

### Claim 2 (depends on 1)

The apparatus as set forth in claim 1 wherein said rotatable framework includes a mounting bracket adapted to be secured to the end of a movable work arm of a powered construction vehicle and a rotatable swivel plate assembly secured to the lower end of said mounting bracket; and wherein said elongated support member is secured to the lower end of said swivel plate assembly.

### Claim 3 (depends on 2)

The apparatus as set forth in claim 2 wherein said swivel plate assembly includes at least four arcuatley spaced radially extending stop members; and including removable locking means for engaging any of said stop means for securing said framework at a select position.

### Claim 4 (depends on 3)

The apparatus as set forth in claim 3 wherein said locking means is elongated sized and shaped for removeably engaging a pair of aligned said stop members.

### Claim 5 (depends on 2)

The apparatus as set forth in claim 2 wherein said swivel plate assembly includes four radially extending stop members generally uniformly arcuately spaced 90° apart; and including removable locking means for engaging any of said stop members for securing said framework at a select position dependent on which stop members are engaged by said locking means.

### Claim 6 (depends on 1)

The apparatus as set forth in claim 1 including a guide bracket means fixed to and extending downwardly from said other end section of said support member and arranged to removeably engage said mandrel at said other end section thereof for aligning said mandrel with said lower end section of said bearing arm.

### Claim 7 (depends on 1)

The apparatus as set forth on claim 1 wherein said elongated bearing arm has an upper end and a lower end and is pivotably secured at an intermediate section thereof to said other end section of said support member.

### Claim 8 (depends on 7)

The apparatus as set forth in claim 7 including power means engaging said bearing arm at an upper portion thereof for impressing a moving force on said bearing arm.

### Claim 9 (depends on 8)

The apparatus as set for the in claim 8 wherein said power means includes a hydraulic drive assembly.

### Claim 10 (depends on 1)

The apparatus as set forth in claim 1 including removable locking means engageable with said framework for securing said framework from rotation.

### Claim 11 (depends on 1)

The apparatus as set forth in claim 1 including a stop plate means secured at said one end section of said mandrel for limiting the positioning of a roll of sheeting on said mandrel spaced from said free lower end of said bushing assembly.

### Claim 12 (depends on 1)

The apparatus as set forth in claim 1 wherein said framework, said bushing assembly, said bearing arm assembly, arbor assembly and said mandrel are constructed and arranged such that when said apparatus for covering is lowered toward a land area and the apparatus is moved by a construction vehicle a roll of sheeting on said mandrel will unroll and the sheeting will be placed on the surface of the land area.

### Claim 13

Apparatus for covering a large land area with a heavy, wide width, flexible sheeting such as a geotextile clay liner, comprising:
a main framework shaped, sized and adapted for mounting engagement onto the end of a moveable work arm assembly called a crowd of a powered excavator vehicle;
a swivel plate assembly rotatably secured to the underside of said main framework;
an elongated support member fixed at an intermediate section thereof to the underside of said swivel plate assembly for rotation with said swivel plate assembly;
a downwardly extending bearing arm assembly having a proximate end pivotably fixed to one end section of said support member and a free lower distal end;
power means engaging said bearing arm at an upper end portion thereof for impressing a moving force on the pivotable bearing arm;
a downwardly extending bushing assembly pivotably mounted on the other end section of said support member;
an arbor assembly including an elongated mandrel sized and shaped for receiving and supporting a roll of heavy weight liner sheeting and having one of its ends journalled in said bushing assembly and its opposite end removably arranged in the lower end section of said bearing arm;
wherein when aid bearing arm is pivoted away from said other end of said support member the mandrel is released from said bearing arm and is pivoted downwardly whereby a roll of heavy sheeting may be placed on said mandrel; and when said bearing arm is pivoted toward said opposite end of said mandrel said opposite end of said mandrel is received in said bearing arm;
removable locking means engageable with said swivel plate assembly for selectively securing said swivel plate from rotation; and
wherein said main framework, said swivel plate assembly, said support member, said support arm, said bearing arm, said power means, said bushing assembly, said arbor assembly, and said mandrel are constructed and arranged such that when said apparatus for covering is lowered toward a land area and the apparatus is moved by an excavation vehicle a roll of heavy sheeting on said mandrel will unroll and the sheeting placed on the surface of the land area.

### Claim 14 (depends on 13)

The apparatus as set forth in claim 13 including a guide bracket means fixed to and extending downwardly from the other end section of said support member and arranged to removably engage said mandrel of the other end section thereof for aligning said mandrel with said lower end section of said bearing arm.

### Claim 15 (depends on 13)

The apparatus as set forth in claim 13 wherein said power means includes a hydraulic drive assembly.

### Claim 16 (depends on 13)

The apparatus as set forth in claim 13 wherein said swivel plate includes a plurality of radially extending, arcuately spaced stop members; and wherein said removable locking means cooperates between a pair of aligned said stop members.

### Claim 17 (depends on 13)

The apparatus as set forth in claim 13 including a stop plate means secured at said one end section of said mandrel for limiting the positioning of a roll of heavy sheeting on said mandrel and spaced from said bushing assembly.
