Patent Model For Carpenter’s Combination Tool, Patent No. 70,547, Bevel and Try Square
This is a Patent Model for Carpenter’s Combination Tool, Patent No. 70,547.
This object is not part of the Cooper Hewitt's permanent collection. It was able to spend time at the museum on loan from National Museum of American History as part of Tools: Extending Our Reach.
The patent for John Graham’s combination tool listed several carpentry tools including a bevel, marker, gauge, try square, and level—what Graham described as an "indicator." When the square was placed upon a surface, the indicator pointed vertically to twelve o’clock if the surface was level, varying to the left or right if not. The indicator was Graham’s main invention in his patent, but he also claimed "the combination of one or more supplemental movable or adjustable squares, with a try-square." This claim made Graham’s invention a multitool, a carpenter’s Swiss-Army knife of bevels, levels, and squares.
