Article on Gilkerson's Planer Vise
Vintage Machinery entry for Gilkerson Machine Works

Description: |
| The 1885-11-14 American Machinist, page 7, has an article on Gilkerson's planer vise, which was made by the Gilkerson Machine Works of Homer, N. Y., in nine sizes from 4 to 24 inches width of jaw. The design shown in that article differs substantially from the patent in that the floating jaw attaches to its carrier by a beveled surfaces that tends to force the jaw downward as the adjustment screw is tightened. The patented vise provides three adjustment ranges of the movable jaw by means of pins protruding from either side of the base and hook-arms ("links") attached to either side of the jaw. The vise as implemented does away with this feature altogether, which means that even though the vise was advertised as "patented", the vise as built does not use the patented features. There is little doubt that in the overall design that the Gilkerson planer chuck is descended from the design shown in this patent. |
