Patent ID: 7201062

Claim:
A device adapted for pulling the ends of a continuous chain together, in order to measure the tension in the chain, the continuous chain including at least five serially interconnected links the first and fifth links each have an opening through the link, each opening being completely surrounded by the link, the device comprising a first straight section, a second straight section, a third section that is connected to the first straight section to form an L shaped piece, and a fourth section connected to one of the first and second straight sections to form an L shaped piece, and means for pinning the four sections together, so that the device surrounds the chain end links so that the ends of the chain can be pulled together to measure the tension in the chain, wherein the second section is removably pinned to the third and fourth sections, so that, when the third and fourth sections are unpinned from the second section, the third section can pass through the opening in the first link, and the fourth section can pass through the opening in the fifth link, so that when the third and fourth sections are again pinned to the second section, the device is held within the continuous chain.
