Description: |
| This coordinates with a wrench jaw of the type described in Booth and Redfield's June 13, 1893 patent (no. 499,508). This patent addresses the chain, which has pivot pins extending from the outer link plates of the chain. The pins align with the centers of the rivets connecting the links. The centers of the pins have countersunk holes, so the heads of the connecting rivets are concealed within the chain.
