label: Description
content: This is a patent model of a file cutting machine, patented by Alfred Weed of Boston, Massachusetts in July 1873.
label: Description
content: Alfred Weed’s improvement in file-cutting machines consisted in attaching a shoe or feed-foot to the cutter-arm, so that when the cutter was raised after a stroke the shoe bore against the spur of the newly-formed tooth and fed the file forward. As the cutter descended again, the shoe was lifted from the file, while a spring-pressed pin held the file firmly in place. By this arrangement the file was automatically advanced the proper distance at each stroke, securing uniformity and efficiency in the cutting of teeth.
