Description: |
| This valve is intended for use in powering a drag-saw. It seems likely that this invention was adapted to gasoline engines as used by the Thomas Engineering Works, makers of the "Bear-Cat drag saw. That saw was claimed to be patented and this patent is the best candidate we have found. |
