Washington's Watch Chain

The lifting devices, like the capstan, lever, block and tackle, are all easily portable and go back to ancient Roman times. The chain was made of formidable 2½-inch thick iron, each link was twenty six to thirty eight inches in length, weighing approximately one hundred pounds each, with nine or ten links to a section, plus a huge joining clevis and a swivel. It certainly was effective. The British never attempted to break it.
