[Illustration: Fig. 58. Sensitive Gear-testing Gage] In Fig. 58 is shown a sensitive gage for inspecting small bevel gears. The special case shown to which the gage is applied in the engraving is a small brass miter gear finished on a screw machine, in which case some of the holes through the gears were not concentric with the beveled face of the gears, causing the gears to bind when running together in pairs. The gage shown is quite inexpensive, but it indicates the slightest inaccuracy. * * * * * NOTES [1] MACHINERY, October, 1897. [2] M. H. Ball, April, 1902. [3] M. H. Ball, February, 1901.
