notes: label: Description
content: This object is a patent model of U.S. patent No. 190,260, a combined gauge, try-square and trammel, patented on January 29, 1877, by Benjamin F. Stoner of Illinois. Stoner sought to invent a tool that could be used as a gauge for all irregular surfaces and for places that an ordinary gauge couldn’t reach. The tool has a rectangular head with an adjustable screw running through it. Upon this rod are measurement marks, and the rod can be adjusted to be longer or shorter with these. At the middle of the rod is the adjustable pivot-finger of the trammel, and at the end (opposite the head) is an adjustable marking needle. All of the adjustable items can be changed and set in place through set screws.
