Description: |
| A rod with flattened and tapered end is formed into a loop with the flat tapered section twisted into a section of the rod, forming a loop handle. The specifications describe this as a "duplex spiral twist."
The patent matches screwdrivers advertised by the company to which it was assigned, and successor firms.
The same "duplex spiral twist" appears in design patents D19,980 and D19,981 in a trap door handle and tack lifter. |
