Description: |
| Originally patented in England, GB-184,209,382. Original US patent was number 3,042, issued 1843-04-10 and then reissued 1846-09-10, RE86. This reissue was assigned to the partners of the Southwark Foundry in Philadelphia, which had licensed this patent and were paying a royalty of $1800 per hammer, equivalent to over $60,000 today, although inflation calculations are very inexact over such long time-spans. |
