Object detail

4 x 12 x 4" (10.2 x 30.5 x 10.2cm)
John Smith was deceased at the time the patent application was filed, so it was filed on his behalf by his executors - William G. Bates of Westfield, Massachusetts and Catharine S. Smith of Kingston, New York.

The nature of Smith's "discovery consists in applying heat to the barrel or other vessel in which gunpowder is being glazed, while the process of glazing is going on, thus combining the process of drying with the process of glazing gunpowder, and performing both at the same time." (Patent Number 46,275)
