Description: |
| This vise was manufactured by the Union Vise Co., which, after an 1871 fire, sold their vise line to the Backus Vise Co., which in 1873 became part of the newly formed Millers Falls Co."The nature of my invention consists in the arrangement, with the deeply-recessed stationary jaw and the screw-shaft, of the protecting and sliding flanged support..."A correspondent reports a copy of an agreement, dated June 1869, between Andren and the Union Vise Co., with the company purchasing all rights to the vise.This patent seems to be an improvement on patent 78,565, granted one year previous to Quimby Backus of Winchendon, MA. Where Backus's patent uses nested sliding tubes to keep the vise-screw clean, Andren recesses the screw into the stationary jaw, and uses a single sliding tube to protect the rest of the screw. A flange on the end of the sliding tube helps prevent the movable jaw from sagging—a potential problem because the recess in the stationary jaw reduces the amount of support given to the vise-screw. |
