”37. For an Improvement in Mills, for Grinding all kinds of Grain, &.; Justin Ware, Farmington, Trumbull county, Ohio, July 20. The patentee says,—’The principle of this machine is the combination of the screw principle of Paine & Russel’s patent apple grinder, caused by the spiral flutes and ridges, the breaking principle of the com cracker, by notching half of the ridges, as described in the foregoing specification, and the coffee-mill principle, in the floats or fine teeth at the lower part of the concave and convex.’

Claim.—What I claim as my invention and discovery, and which I desire to secure by letters patent, is the combining of the above mentioned principles of the screw, formed by the spiral flutes and ridges, the breakers, by notching every alternate ridge, and the small teeth or floats at the bottom of the concave and convex, so as to perform, with one machine, the business of the common corn shelter, of the corn cracker, in preparing ears of corn to grind, of the common grain mill, in grinding it, and all other kinds of small grain for provender, of grinding stone coal, plaster, and potter’s clay, and, by removing that part in the concave containing the small teeth, to grind apples and all other soft vegetables.’ ”
