Claims20
A wireline apparatus, comprising:
- a receiving side wall comprising a plurality of first roller holes disposed to form an arcuate shape;
- a roller side wall comprising a plurality of second roller holes disposed to form an arcuate shape;
- a first roller chain comprising a first plurality of roller bodies disposed to form an arcuate shape about a point above the receiving side wall and the roller side wall, the first plurality of roller bodies being connected between the roller side wall and the receiving side wall;
- a second roller chain comprising a second plurality of roller bodies disposed to form an arcuate shape about a point below the receiving side wall and the roller side wall, the second plurality of roller bodies being connected between the roller side wall and the receiving side wall;
- a plurality of bearing pins each supporting one of the roller bodies of the first and second pluralities of roller bodies, the pins being operably configured to couple with the plurality of first and second roller holes;
- and
- a hinged door and a securement roller body, the securement roller body comprising a roller, being carried by the hinged door and being disposed to cooperate with the first roller chain to capture a wireline therebetween.

A wireline apparatus, comprising:
- a receiving side wall;
- a roller side wall;
- a first roller chain disposed between the receiving side wall and the roller side wall;
- a second roller chain disposed between the receiving side wall and the roller side wall, the first and the second roller chains together forming an S-shape for the direction of a wireline;
- a securement roller body adjacent the first roller chain, the securement roller body comprising a roller and being displaceable between a first location securing a wireline between the first roller chain and the securement roller body and a second location allowing the wireline to be laterally introduced between or removed from between the first roller chain and the securement roller body.
