Sobre este artículo
Designed by Mr. Aaron Palmer and Mr. George G Smith in early 1841, a prototype was shown in early 1842, and later in Boston in the fall of 1843. It was first released commercially in 1843, and underwent a continual, if minor, set of changes during the next few years. We have yet to find two examples of this device that are exactly the same, and suspect that only a few were made at one time allowing for dynamic changes as needed. Fuller later bought the rights and added a second wheel (the Time Telegraph) to the rear and publishing the instructions separately, starting in 1845.
This is a later example (still within a few years of original publication but before Fuller bought the rights in 1845). The rear board has four columns of text and many examples of the application of the slide rule rather than a list of guage points as in earlier examples. It also notes in the lower left 'Stereotyped by T. S. Sprague, Hartford, CT' and the printer's name (Ela) is no longer present as it is in earlier examples.
