Description: |
| This patent covers the pin-and-scallop joint, for which inventor Knapp had already patented machinery. This type of joint (and hence the machinery to make it) was very popular in the late Victorian era. It is quite distinctive and is often seen on antique furniture of the appropriate era. See also patents 63,532, 122,390, and 388,760. |
