Description:
This patent is for a large-scale ratchet suitable for heavy construction such as connecting bolts for bridge trussses. The ratchet pawls are operated by gravity, or disengaged by hanging from a spring. Each pawl operates against a separate rack, and bears against the handle frame. The ratchet head turns on roller bearings, and has provision for inserts to fit various sizes of nuts.
