Description: |
| This patent is an improvement of patent #1,155X.
Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2000 of the almost 10000 documents were recovered. Little is known about this patent. Only the patent drawing is available. This patent is in the database for reference only.
"On the 17th May, 1828, Mr. Ravenel obtained a patent for a mortar for cleaning rice. The bottom of this mortar was solid, but the sides were composed of wove wire, supported by ribs; this formed a sïeve, which allowed the flour, or dust, which is formed in the pounding, to escape; which dust, in the ordinary mortar, causes the materials to heat, and greatly retards the operation. In the present patent, these mortars are used, but it is proposed to move the pestles by cranks, which will prevent their approaching too near the bottom of the mortar, so as to break the rice: this plan had been patented by Mr. King Mr. Ravenels improvement consists in the addition of a flywheel to regulate the motion, and in the mode of adjusting and placing the mortars under the pestles, so that either may be removed without disturbing the remainder."
