Combination master link and chain shortener
View Patent ↗A combination master link and chain shortener that can be readily connected to existing closed loop lifting rings. In one preferred embodiment, a bail connects to a lifting mechanism and an elongated body having a pair of opposed ends includes an opening at one end to connect to the bail. A pair of chain shortening cradles are provided, each chain shortening cradle in angular relation to the elongated body. A pair of chain connecting hooks, each receive a chain end link therein. A chain retainer pin retains the chain end links within the connecting hooks. In an alternate embodiment, a bail connects to a lifting mechanism and an elongated body includes a pair of opposed ends with an opening at one end to connect to the bail. A pair of chain shortening cradles are provided with each cradle in angular relation to the elongated body. A pair of receptacles are provided at an opposite end of the body in order to receive a pair of chain end links. A single pin passes through the receptacles in order to lock the pair of chain end links in the receptacles.
1. A combination master link and chain shortener replacement device which comprises:
an open loop bail having a bail opening, said bail suspended from a lifting mechanism and readily attachable to said lifting mechanism;
an elongated body having a pair of opposed ends with one said end connected to said bail at said bail opening;
at least two chain shortening slots in said body, each said slot in angular relation to said elongated body;
at least a pair of chain end link receptacles at an opposite end of said body having a chain end link in each said receptacle; and
a single retaining pin passing through each said chain end link and each said receptacle to lock each said chain end link in said receptacle.
2. A combination master link and chain shortener replacement device as set forth in claim 1 wherein said single retaining pin passes through said chain end link receptacles of said body parallel to said bail opening at said one end of said body connected to said bail.
3. A combination master link and chain shortener as set forth in claim 1 wherein said single retaining pin is perpendicular to a hinge opening at said one end of said body.
4. A combination master link and chain shortener replacement device as set forth in claim 1 wherein each said chain shortening slot has a thickness and each said slot includes an extending saddle having a thickness larger than said thickness of said slot.
5. A combination master link and chain shortener replacement device as set forth in claim 4 wherein each saddle includes an extending end having a concave recess to provide maximum support to promote strength of a chain link therein.
6. A combination master link and chain shortener replacement device as set forth in claim 1 including a link limitation and orientation shoulder in said body adjacent each chain end link receptacle.
