Description: |
| Newfoundland did not assign patent numbers; for Newfoundland patents issued after 1869 we have synthesized numbers as the year multiplied by 1000, plus the number of the patent for that year.The inventor was the son of steam-engine manufacturer Thomas Northey, whose firm became Northey & Co. and then Northey Mfg. Co., Ltd.; the Diaphone Signal Co. was a spin-off, created to manufacture foghorns and similar devices. |
