Description: |
A very complex solution to the problem of quickly setting the rip fence on a tablesaw. This invention requires a track embedded in the table surface, which has holes spaced and labeled every inch. The fence assembly has a cam-shaped disk with 33 holes around its periphery, labeled 0 through 32. To set the fence to, say, 3 23/32 inches, a pin is dropped though the "23" hole of the cam into the "3" hole of the track.This seems like a good design except for the fatal flaw that it is too expensive to manufacture. Simpler approaches using verniers or a boring old-fashioned tape measure have won out.The inventor subsequently simplified the design somewhat in patent 816,424.The August 1909 issue of "Wood Craft" describes the "Bemis positive-set saw gage" and says, "These saw gages are manufactured by Thomas Bemis, Industrial building, Indianapolis, and he also makes gages to rip wider than 50 inches." |
