UNITED STATES PATENT OFFICE.
JOHN D. MINES, OF MOFFETTS GREEK, VIRGINIA,'ASSIGNOR TO HIMSELF` AND W. Il. TETER,
OF SAME PLACE.A
IMPROVEMENT IN MlLLSTNE-DRESS.
Specification forming part of Letters Patent No. 154,268, dated August 18, 11574; application Sled I April 10, 1874.
To `all whom it may concern:
Beit known that I, JOHN D. MINES, of Moffetts Creek, in the county of Augusta and State of Virginia, have invented a new and f Improved Mill-'Burr Dress; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to Jthe accompanying drawing forming a part of this speciication, in which- Figure l is a sectional elevation, and Fig. 2 a top or plan view of the bottom stone.
The invention relates to means whereby a mill-burr may be dressed so as to prepare the widening at the ends or otherwise. B is my f( center-dress, which is an annglar copcanitya!.J'LWU` about eight or ten deep ard the eye J' of the burrs, the excision from the stones being so made as to form a square shoulder, b, of the same depth. This serves to crush the grain, and not grind it intoA dust or powder before i-t comes between they grinding-faces, the bran being thus left larg' 'and flat.
The resistance to the power employed is found, by practical experiment and observation, to be greatly diminished, so that the mill may thus be run with much less power or water than usual.
Having thus described my invention, what I claim las new is- Burrs or stones for grinding grain, provided with faces having a center-dress consistingoi an annular depression, B, with shoulder b, as and for the purpose described.
JOHN D. MINES.

W. L. TETER, J. F. HITE.
