Description: |
| S. W. Bates - patent attorney
Claim:
The object of our invention is to construct a V-block which will be adapted to working all diameters which are commonly used in machine-shops and which may be extended to support various lengths. To this end we form our tool of a pair of V-blocks having the notches in line with each other, connecting them by means of one or more guides, upon which one of the blocks is adapted to slide, so that the distance between them may be increased or diminished at will. |
