Classic leather gage made by C. S. Osbourne. This patent is for a sliding gage bar with a cutter utilizing a cam to secure the gage bar and cutter as well as an adjustable size handle. Observed production models utilized a thumb screw to secure the bar and cutter and do not have an adjustable handle. In this reissue, the number of claims increased to seven claims from three claims, with the form and function the same but several more details are claimed (pistol grip and finger hold) but are shown on the original patent drawing.
