Automatic band saw setting machine worked by hand

Automatic band saw setting machine worked by hand, by M. Glover & Co., Patentees and Engineers, Leeds, 1911

This is a machine for sharpening band or other similar saws by means of a circular file or fine toothed milling cutter rotated by hand.

The saw blade is mounted below the file in an adjustable clamp, and the file is made with a notch at one point on the circumference, in which is fitted a steel cam-plate that feeds the saw forward by one tooth for every revolution. Such a machine sharpens all the teeth uniformly and at the rate of about 4 ft/min.
