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 chain fastener passes through one eyelet, passes through one of the chains, 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, where each of said chains has a plurality of links;

a plurality of parallel wire lines traversing the tarp;

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

a chain fastener passing through said eyelet, passing through one of said links of one of said chains, and passing through said tarp; and

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

2. A 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, opposed end hollow recess.

3. A 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.

4. A weight system for a landfill tarp as set forth in claim 1 wherein each said wire line fastener is a recessed set screw.

5. A weight system for a landfill tarp as set forth in claim 1 wherein each said opening in said coupler body is threaded and including a plurality of said wire line fasteners arranged circumferentially around said body.

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

7. A 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.

8. A weight system for a landfill tarp as set forth in claim 1 wherein said chain fastener comprises a bolt and nut.

9. 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, where each of said chains has a plurality of links;

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 terminating in a hollow recess;

a chain fastener passing through said eyelet, passing through one of said links of one of said chains, and passing through said tarp; and

at least one wire line fastener passing through an opening in said coupler body and engaging one of said wire lines wherein each said opening in said coupler body is threaded.

10. A weight system for a landfill tarp as set forth in claim 9 wherein each said wire line fastener is a recessed set screw.

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

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

a pair of parallel chains retained within a pair of sleeves in said tarp, where each of said chains has a plurality of links;

a plurality of parallel wire lines traversing the 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 terminating in a hollow recess;

said connection mechanism securing said coupler body to one of said links of one of said chains; and

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

13. 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 terminating in a hollow recess;

a chain fastener passing through said eyelet, passing through a chain with a plurality of links, where said chain fastener passes through one of said links, and passing through a tarp securing said coupler to said chain and said tarp; and

a wire line fastening mechanism securing an end of a wire line in said hollow recess of said second, opposed end.

14. A coupler for a landfill tarp weight system as set forth in claim 13 wherein said wire line fastening mechanism includes at least one wire line fastener passing through an opening in said coupler body and engaging said wire line in said hollow recess.

15. A coupler for a landfill weight system as set forth in claim 13 wherein said coupler body first end is flattened.
