Abstract

A weight system for a landfill tarpaulin. A pair of parallel chains are retained, within a pair of sleeves in the tarp. A plurality of parallel wire lines traverse the tarpaulin. A plurality of elongated coupler bodies are provided with each coupler body having a first end terminating in a eyelet and a second, opposed end terminating in a hollow recess. A fastener passes through one eyelet, and passes through the tarp. At least one wire line fastener passes through an opening in the coupler body to engage one of the wire lines received in the second, opposed end hollow recess.

Claims

1. A weight system for a landfill tarp, which comprises:

a pair of parallel chains retained within a pair of sleeves in said tarp;

a plurality of parallel wire lines traversing said tarp;

a plurality of elongated coupler bodies, each elongated coupler body having a first end terminating in an eyelet and a second, opposed end;

a fastener passing through said eyelet in said first end and connecting to said tarp, wherein said fastener passing through said eyelet connects directly or indirectly to one of said sleeves in said tarp for said chains; and

a wire line fastening mechanism securing an end of one of said wire lines to one of said second, opposed ends of said elongated coupler bodies.

2. The weight system for a landfill tarp as set forth in claim 1 wherein said wire line fastening mechanism includes at least one wire line fastener passing through an opening in said coupler body and engaging one of said wire lines received in said second end.

3. The weight system for a landfill tarp as set forth in claim 2 wherein each said wire line fastener is a recessed set screw.

4. The weight system for a landfill tarp as set forth in claim 1 wherein said tarp, said parallel chains, said plurality of wire lines, and said plurality of coupler bodies wind on a spool with said parallel chains winding circumferentially around said spool.

5. The weight system for a landfill tarp as set forth in claim 1 wherein each said coupler body first end is flattened.

6. The weight system for a landfill tarp as set forth in claim 1 wherein each said wire line is retained within a sleeve in said tarp.

7. A weight system for a landfill tarp, which comprises:

a pair of parallel chains retained within a pair of sleeves running the entire length of said tarp;

a plurality of parallel wire lines traversing said tarp, each said wire line retained in a sleeve of said tarp;

a plurality of elongated coupler bodies, each elongated coupler body having a first end terminating in an eyelet and a second, opposed end;

a fastener passing through said eyelet in said first end and passing through said tarp, wherein said fastener passing through said eyelet connects directly or indirectly to one of said sleeves in said tarp for said chains; and

at least one wire line fastener at each said second end in said coupler body engaging one of said wire lines.

8. The weight system for a landfill tarp as set forth in claim 7 wherein each said wire line fastener is a recessed set screw.

9. The weight system for a landfill tarp as set forth in claim 7 wherein said each coupler body first end is flattened.

10. A weight system for a landfill tarp, which comprises:

a pair of parallel chains retained within a pair of sleeves in said tarp;

a plurality of parallel wire lines traversing said tarp;

a plurality of elongated coupler bodies, each elongated coupler body having a first end terminating in a connection mechanism and a second, opposed end;

said connection mechanism securing said first end of said coupler body to said tarp, wherein said connection mechanism is directly or indirectly secured to one of said sleeves in said tarp for said chains; and

a wire line fastening mechanism securing an end of one of said wire lines to said second, opposed end.

11. A coupler for a landfill tarp weight system, which coupler comprises:

an elongated coupler body having a first end terminating in an eyelet and a second, opposed end;

a fastener passing through said eyelet and directly or indirectly connecting said first end of said coupler body to a sleeve in a tarp for a chain; and

a wire line fastening mechanism securing an end of a wire line to said second, opposed end.
