Vintage Machinery entry for Frank Thompson
|
|
Description: |
| Of interest because a Frank Thompson was manufacturing wood-turning lathes in New York in 1884. We cannot be certain that this patent was granted to the same Frank Thompson. We did find an ad in The Polytechnic Engineer for "Established 1887 / Frank Thompson / Practical plumber and gas fitter ... 196 Flatbush Avenue". |
