Description:
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.

“For a machine for the purpose of Washing Alluvial Earth, Clay, and Soft Ores, and separating and saving the gold from the same; William H. Folger, Mechlenburg County, North Carolina, September 10.

A principal part of the apparatus described in the specification of this patent is called a tipping box, in which the earth, &c. is to be agitated with water, for which purpose the box is suspended upon pivots. There are also described instruments for grinding, raking, and other purposes, which do not appear to us to offer anything of special interest, or novelty; they, however, are minutely described, and collectively claimed in the following words. “I claim as original the things above described, and the manner of using them, with the exception of the bevel wheels, trundles, and cog wheels, and moving power.”
