MILLSTONE DRESS.

UNITED STATES PATENT OFFICE.
ELGIN L. CONKLIN, OF OORNING, NEW YORK.
MILLSTONE-DRESS.
V SPECIFICATION forming part of Letters Patent No. 269,015, dated December 12, 1882.
Application filed August 21, 1882. (No model.)
1' 0 all whom it may concern:
Beit known that I, E. L, GONKLIN, of Gorning, in the county of Steuben and State of New York, have invented certain new and useful Improvements in Millstone-Dress; and I do hereby declare the following to be a full, clear, and exact description of the invention, such'as will enable others skilled in the art to which it pertains to make and useit, reference being bad to the accompanying drawings, which form part of this specification.
My invention relates to an improvement in inillstone-dress forstone ormetallic disk mills;
and it consists in the combination of curved furrows, which radiate from the eye of the stone, and which are separated from each other by flanges which rise to the level ot'the land-. surface, with radial furrows which extend from theoutcr ends otthe curved grooves or furrows to the skirt ofthe stone, as will be more fully described hereinafter.
The object of my invention is to provide a dress which is specially adapted to breaking the grain so as to prepare it for further reduction, and in which the furrows are so formed that the stone will work cooler and make more and better middlings than can be obtained in the usual way. 1 V
Figure l is a plan view of my invention. Fig. 2 is a perspective detail sectional view.
A represents a stone or runner, which may be formed of iron, steel, or other suitable ma terial.
Leading out from the eye of the stone are a number of curved grooves B, which are deeper and narrower at their inner ends than at their outer ends. The flanges l), which sepa rate these grooves, are on a level with the landsurface of the stone, and will be preferably laid out upon an outer circle, though the curve may be greater or less, as may be desired. The curved ribs, or dividing flanges prevent the grain from flowing around the eye and being secured, and at the same time force it out and spread it in one even and unbrokensheet upon the lands or ribs, where the grains are broken. These curved grooves are made deepest at their inner ends, so that the grain will flow freely into them and follow the direction of the curved flanges or divisions until it reaches the outer ends of the grooves where they are no deeper than the radial furrows F, which extend out over. the stone.
Thecurved furrows at their outer ends have the radial furrows F extend into them, and the only escape for the grain from the curved furrows is directly into the radial ones. lhere may be four radial furrows and four land-surfaces to each curved furrow, or there may be a greater number, as may be preferred. The radial furrows are made wider and deeper in proportion to width at their outer than at their inner ends,or may beofequal width and depth, so that the grain will flow freely from the stone without having become heated in the grinding or breaking. These radial furrows are made triangular in shape, being deepest on front edge, a, and rising gradually back to the level of the laud-surfaces.
Across the land-surfaces may bemade any suitable smaller grooves or corrugations,which will run parallel to the'radial furrows, and
stones will work easier and make more and better middlings without heatingthan can be done in the usual manner.
The radial furrows may have any desired draft even to a reversed draft, from that of the curved furrows.
Having thus described my invention, I claim- In a millstone-dress,the combination of the curved furrows B, deepest and uarrowest at their inner ends, separatingflanges D, which rise to the level of the land-surface, and the radial furrows F, substantially as shown anddescribed.
In testimony whereof I affix my signature in presence of two witnesses.
