"Vintage Machinery" entry for Henry Disston & Sons
Description:
Robert C. Barrie - patent attorney

From about 1885 to 1910, Disston made a variety of Machinist's tools.

This invention relates to that class of devices, which are used by mechanics in truing up work of different forms, and it has for its object to furnish a gage for square corners, hexagonal corners, and equilateral triangles, for finding the center of a square, for measuring the angle of a center hole, and for measuring the depth of apertures. I am aware that gages for trying squares and angles of sixty degrees, also narrow rules for measuring, are common.
