"Vintage Machinery" entry for W. T. Nicholson
Description:
The invention described in this application is one of several improvements in machines used for the purpose of stripping or draw-filing file-blanks, for the several divisions of which invention I have made three other applications for Letters Patent, all of even date herewith. This part of my invention consists, first, in an improved arrangement by which reciprocation is imparted to the file-blank, and a movement given to it which approximates in its figure to the figure 8; second, in the arrangement by which an elastic, yielding, and self adjusting support is given to the file or tool, which effects the stripping; third, in the construction of the file-blank bed, by which the file-blank is enabled to adjust itself to the face of the stripping-file; fourth, in a peculiar arrangement by which the file-blank is held in contact with the stripping-file, which contact is partially relieved when the blank passes backward from under the same.
