GERMAIN BERNARD, OF MONTPONT, FRANCE.
MILLSTONE DRESS.
SPECIFICATION forming part of Letters Patent No. 306,573, dated October 14, 1884.
Application filed November 12, 1883. (No model.) Patented in France March 19, 1883, No. 153,642.
To all whom it may concern:
Be it known that I, GERMAIN BERNARD, a citizen of the French Republic, residing at Montpont, in France, have invented new and useful Improvements in Millstone-Dress, of which the following is a specification.
My system of furrows produces the followin g advantages: A more considerable quantity of flour is produced by the stones, and the quality thereof is also much improved, as a stone dressed according to this method driven by five-horse power will grind two hundred and fifty kilograms of corn in an hour, while the old dressing allows only,at most,a hundred kilograms. Moreover, this flour is not heated, a greater quantity of air being drawn under the stone.
Figure 1 shows part of a millstone dressed according to my invention. Fig. 2 shows a vertical section of a stone so dressed, taken on line C D, Fig. 1, and it will be there seen that the width of the furrows in this first section of the dress equals that of the land between any two of them. Fig. 3 shows a vertical section of such a stone, taken on line EF, Fig. 1, and it will be seen that the furrows are turned in a direction opposite to those above de scribed, and have no lands between them. These form the second section of the dress. Fi at shows avertical section of the stone on line A B, Fig. 1, where the bosom of the stone is shown hollowed out, to allow the grain to be introduced. The furrows in the first section of this dress, comprised between the lines I M, Fig. l-that is, the part called the skirt ing of the stoneare curved to facilitate the delivery of the flour as it is being produced, in order that it may be delivered ina looselyground state, as otherwise its quality would not be as good. The furrows cf the second section, comprised between the lines H I, Fig. 1, called the breast of the stone, are slightly curved in a reverse direction to those of the skirt. These curves, however, are such that it continued inward toward the eye of the stone they would not pass through its central of the bosom and breast sections in the direction of their length. In the third section (the bosom) the furrows comprised between the lines G H are only a prolongation of the furrows in the second section, the number whereof is reduced to half. The lesser number of furrows in the bosom-section permits, in the same period of time, a larger quantity of grain to be acted upon and expelled than if the furrows were more closely arranged. It also securesa greater draft than if the furrows in both the breast and bosom sections were of like number and continuous.
The grain, when subjected to the action of the bosom-section, is roughly cracked or split. I11 the breast-section it is reduced to groats and bran, the eccentric furrows in each case facilitating its outward passage to the skirtsection. In the latter, by reason of the regular curvature of the furrows, it is detained for a relatively longer period, and upon the lands, which are of uniform width with the intermediate grooves, it is gradually and effectually reduced to asmooth and uniform consistency.
. \Vhat I claim is "The millstone-dress hereinbefore described, consisting of three separate furrow-sections, the furrows of the inner or bosom. section and of the breast-section being slightly curved in directions coincident with each other and eccentric to the center of the eye, and the outer or skirt section being provided with lands of equal width throughout to the width of the furrows in such section, as set forth.
