UNITED STATES JOHN'M. SPEER, JR, OF
PATENT OFFICE.
FORT BRANCH, INDIANA.
M l LLSTONE- DRESS.
SPECIFICATION formingpart of Letters Patent No. 257,623, dated May 9, 1882. Application filed February 28, 1852. (No model.)
To all whom it may concern:
Be it known that I, JOHN M. SPEER,J1., of
Fort Branch,in the county of Gibson and State of Indiana,haveinvented certain new and useful Improvements in Millstone-Dress; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
Figure l is a plan view of a millstone having my improved dress 5 and Fig. 2 is a vertical sectional view on the line as m, Fig. 1, of a run of millstones having my improved dress.
Similar letters of reference indicate corre-.
sponding parts in both figures.
This invention relates to certain improvements in millstone-dress, which will be hereinafter fully described, and particularly pointed out in the claim.
In the drawings hereto annexed I have shown the stone provided with two sets of lands and furrows, which are separated by a circular furrow, A, concentric with the eye of the stone. Inside of the circular furrow A the stone is dressed with tangential furrows B B,which are of equal width throughout, so that they shall meet or run into each other near the eye of the stone within the circle 0. (Shown in dotted lines in Fig.1.) By this construction the stones will readily take the grain as it is fed at the eye. The furrows B have vertical sides a and slanting sides I), which may be at a greater or smaller angle to a the sides (1, according to the draft which they are desired to have. The lands Dbetween the furrows B are all of the same size and triangular in shape. They aredressedlevelandsomewhat lower than the lands outside the circular furrow A, as will be presently described. The furrows B are made to increase slightly in depth toward the eye of the stone. Theinner side, 0, of the circular furrow A is vertical and the outer side is slanting, so that the granulated grain shall readily enter the furrows E outside said circle. The furrows Bare in line with the furrows 13, of whichthey may be said to form continuations; but they are made with less draft than the furrows B. The lands F between the furrows E are dressed level, but somewhat higher than the lands D of the inner circle, for the obvious purpose of reducing the grain more finely.
By making each set narrower more than two setsof lands and furrows maybe formed, the lands of each additional outersetbeingdressed higher and the furrows with less draft than those of the inner adjoining set.
In dressing the lands of the inner circle or circles I avail myself of staffs reachingacross such lands only, or of a length not exceeding the diameter of the furrow A, encircling such lands, as shown by the dotted lineG in Fig. 1. To dress the outer lands I avail myself of a staff of the full diameter of the stone, as shown by the dotted line H.
By means of my improved dress the grain can be gradually and evenly reduced to flour or only granulated to be finished with rollers. The runner and bed-stone are to be dressed exactly alike, and they will produce a firstclass article of flour.
Having thus described my invention, Iclaim and desire to secure by Letters Patent of the United States- As an improvement in millstone-dress, the circular furrow A, the tangential furrows B, increasing in depth toward the eye of the stone and meeting or running into each other near the eye, the level lands D, dressed low, the furrows E,'ot' less draft than the furrows B, and the lands F, dressed high, substantially as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses. 1
