Description: |
| Frank Millward - patent attorney
My invention consists of an emery-wheel or grind stone of small diameter, journaled in a surrounding case, and fitted with driving friction-gearing and adjustable devices, the object of my invention being the production of a tool-grinding device which can be driven by either step on the cone-pulley of the lathe,, and which will, when run at a high velocity, serve to shape the point of a lathe-tool or other instrument; and thus dispense in a! great measure with the frequents and often long trips to the ordinary machinists' grindstone. |
