This company was named after Charles Butler Knapp's dovetailing machine, which made Knapp joints, also known as the cove and pin joint or the pin and scallop joint. See the pictures accompanying the patents - click on the link in the patent section to view the list of patents, and then click on the "DATAMP" link for any of the patents.

Mr. Knapp, who lived in Waterloo, WI, sold the rights to his machine to a group of investors, who set up the company in 1870 in Northampton, MA. Knapp was listed as co-inventor on an 1872 patent for improvements on the original design. That patent was co-invented by one Nathan S. Clement. Mr. Clement received an 1888 patent for improvements to the original invention.

The Knapp joint was very popular, especially in the 1870s and 1880s. It substantially reduced the labor required to make drawers. By 1900, the joint had fallen completely out of favor and the company disappeared.
