Description of an improved Mill for grinding hard Substances; invented by Mr. GARNETT TERRY, of the City Road, Finsbury-square. With a Plate. From the TRANSACTIONS of the SOCIETY for the Encouragement of ARTS, MANUFACTURES, and COMMERCE. The Silver Medal was adjudged to Mr. TERRY for this Invention. THIS mill is calculated for the purpose of grinding hard substances. One has been made on a large scale, which reduces to powder coffee, bones, ashes, and other such things it has also been tried, and found effectual and expeditious in breaking down beans, peas, malt, barley, &c. A, (Fig. 1, Plate IX.) the hopper, or receptacle of the articles which are intended to be ground. B, a spiral wire, in the form of a reversed cone, to regulate the delivery of them. C, an inclined iron plate, hung upon a pin on its higher end the lower end rests on the grooved axis D, and agitates the wire B. D, the grooved axis, or grinding cylinder, which acts against the channelled iron plate E. F, a screw on the side of the mill, by means of which the iron plate E is brought nearer to, or removed farther from, the axis D, according as the article is wanted finer or coarser. G, the handle, by which motion is given to the axis. H, the tube whence the articles, when ground, are received. N. B. The front of the mill is taken off, in order to show its interior construction.
