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 Machinery for Hulling and Cleaning Rice, and Coffee, and for Trip Hammers, Powder Mills, Washing Cloth or Clothes, and for Pounding any kind of Ore or Stone, and for Pounding and Mixing Mortar, for Making Brick, or any other use; Joseph Beach, Middletown, Middlesex county, Connecticut, October 1.
Twenty-five mortars are to be set round in a circle of twenty-nine feet in diameter. The pestles are long vertical pieces of timber, sliding up and down through mortises. These are to be lifted by levers, which converge towards the centre of the circle. By a vertical shaft, four wheels are carried round upon horizontal shafts, which, as they roll, press upon the inner ends of the levers, and thus raise the pestles. These wheels are made wide, that the inner part of their peripheries may be supported upon a circular platform, or railway, whilst their outer edges, projecting beyond the railway, operate upon the levers. The mortars are made in the shape of an egg with the lower end cut off for a small distance; these mortars rest upon suitable blocks, and their upper ends are, of course, open, to admit the pestles.
It is proposed to make longitudinal slits from the top to within six inches of the bottom of these mortars, to allow the dust formed in the pounding to escape. When mortar is to be mixed, ores pounded, or trip hammers worked, the proper troughs or anvils are to take the place of the mortars.
The claim is to "the mode of applying the power by means of wheels to the levers, and the combination of the various parts of the machinery as aforesaid, in such a manner as to produce the result.
The longitudinal slits, and the shape of the mortars, when applied to the cleaning of rice, seem to trench upon Mr. Ravenel's patent, referred to in a note, p. 317, in the last number. In the English patent, on the same page, these longitudinal slits are mentioned. Their effect is the same as the wire work in Mr. Ravenel's mortars, and any claim to them by any person informed upon the subject, would, manifestly, be an attempt to evade his patent.”
