Description
NrrED STATES PATEN HARVEY T. ASHWORTH, OF BERGERS STORE, VIRGINIA, ASSIGN OR TO HIM- SELF AND JAMES T. GRAVES, OF SAME PLACE.
IMPROVEMENT IN MlLLSTONE-DRESS.
Specification forming part of Letters Patent No. 162,878, dated May 4, 1875; application tiled May 16,1874.
T0 all whom vit may concern:
Be it known that I, HARVEY T. AsHwoRTH, of Bergers Store, Pittsylvania county, Virginia, have invented a new and Improved Millstone-Dress, of which the following is a specitication My invention consists of ventilatinggrooves crossing the lands, said grooves being contrived by curving from the periphery, or from that direction backward relatively to the direction in which the stone runs, in a sweep toward the eye so as to have a tendency to draw in the air from the periphery for ventilating the stone. My invention also consists in cracking the lands diagonally in the inner portion of the stone, and arranging those ot one land reversely to those of the next, as a further means of increasing the cutting action.
, Figure l is a section of a millstone having my improved dress, the section being taken on the line x fr, Fig. 3. Fig. 2 is another sec- Fig. 3 is a plan draft from the periphery in a backward direction, which materially assists in circulating air between the stones. E represents the herrin g-bone arrangement of the cracks in the outer portion of the face of the stone, and F the diagonal cracks in the inner portion of the face.
The herring-bone cracks are divided in the middle of the land by a slight furrow or deep crack, which affords a substantial cutting-edge.
The diagonal cracks are reversed in respect of their diagonal inclination in the adjoining lands.
The inner portion of the face is hollowed out, as in other cases, to gradually break the grain down into smaller particles as it works toward the periphery.
Having described my invention, I claim as new and desire to secure by Letters Patentl. The ventilating-furrows traversing the lands from one leader to another, and curved as shown and described.
2. The inner parts F F of the lands, each having cracks inclined in an opposite direction from the next, as shown and described.
HARVEY T. ASHWORTH.
