Abstract
A link coupler for coupling two lengths of different sized chain together and facilitating movement of the two lengths of different sized chain is provided. Also provided is an assembly of the link coupler with a dual chainwheel, a small chain, and a large chain. The link coupler includes a body, a small-chain link coupler coupled with the body at a first end of the body, and a large-chain link coupler coupled with the body at a second end of the body. The dual chainwheel includes a small wildcat profile and a large wildcat profile. The small chain is coupled with the small-chain link coupler, and the large chain is coupled with the large-chain link coupler.
Claims27
An assembly coupling two lengths of different sized chain together and for moving the two lengths of different sized chain together, the assembly comprising:
- a chain assembly including:
- a link coupler, the link coupler including a body, a small-chain link coupler coupled with the body, and a large-chain link coupler coupled with the body;
- a small chain coupled with the small-chain link coupler;
- and
- a large chain coupled with the large-chain link coupler;
- and
- a dual chainwheel including a small wildcat profile and a large wildcat profile, wherein the chain assembly is engaged with the dual chainwheel, and wherein engagement of the link coupler with the large wildcat profile positions the large chain along a path defined by the large wildcat profile.
A method for coupling two lengths of different sized chain together and moving the two lengths of different sized chain together, the method comprising:
- providing a link coupler, the link coupler including a body, a small-chain link coupler coupled with the body, and a large-chain link coupler coupled with the body;
- coupling a small chain with the small-chain link coupler;
- coupling a large chain with the large-chain link coupler, wherein the link coupler coupled with the small chain and the large chain forms a chain assembly;
- engaging the chain assembly with a dual chainwheel, the dual chain wheel including a small wildcat profile and a large wildcat profile;
- and
- hauling-in or paying-out the chain assembly.
