Description: |
| "Our improvements relate to a new combination of mechanical devices by means of which spool-blanks, braid-rolls, or other analogous articles of uniform size and shape are fed or moved, one by one, to a given place, where they are firmly held while a drill or bit advances and bores a hole in or through them." |
