Description: |
| Charles H. Fowler - patent attorney
My invention relates to improvements in a reaming attachment, which can be attached to any screw-plate or die-stock used for threading steam, gas, or water pipe. The object is to ream out the burr at the end of the pipe or pipes caused by the cutting-off tool, the pipe being reamed at the same time that a thread is being cut on it.
