Description: |
| The "Annual Report of the American Institute of the City of New York" for 1858 reports on a discussion on January 12 of that year, about condensers for steam-ships. "Mr. R. G. Eunson explained the condensation and air pump as applied to some western steamers. The air pump cannot be dispensed with, and high steam can be more easily condensed than the low steam—150 pounds on a square inch than 50 pounds... 'I use a hydrostatic pump. There can be no condensing in high pressure engine without air pump.'"The British "Alphabetical Index of Patentees and Applicants for Patents of Invention for the Year 1860", lists John Eunson as having been granted a patent on 1860-01-13 for "Refrigerating apparatus"; the patent was "Communicated by Robert Groat Eunson". It is possible this is a different Robert G. Eunson, because another source mentions that John Eunson was from Wolverhampton; An 1868 ad for the "Wolverhampton Clay Retort Works / Established 1840 / John Eunson and Son, Gas Engineers, &c. ..." Perhaps John Eunson is Robert G.'s father, and Robert moved to New York by 1842, when his first patent was granted. |
