The supporting bearing of the balance-rynd is a central socket called a cockeye, and the supporting point of the spindle which fits the cockeye is called the cock head. The spindle, balance-rynd, and runner-stone are raised or lowered by means of the bridge-tree and lighter-screw to adjust the runner properly in relation to the bed stone. The hopper, p, receives the grain to be ground, and delivers it to the shoe, which is loosely supported, and kept constantly vibrating by the rotation of the damsel, a sort of trundle-wheel, the trundles of which chatter against the shoe. Flour is also made by cylinder-mills or roller-mills. The rollers act by crushing, by crushing and rubbing, as when they are caused to run with different peripheral velocities, or by a cutting or scraping action, as when they are serrated and revolved in such manner that the cutting edges Grinding-mill.

Thou combrest bot he foo & frende, Thi mylle hath grounde thi laste griste. Hymns to Virgin , etc. (E. E. T. S.), p. 74. Much water goeth by the mill that the miller knoweth not of. J. Heywood , Proverbs (1546), ii. 5. Two women shall be grinding at the mill . Mat. xxiv. 41. 2. A machine for grinding or pulverizing any solid substance. The word in this use is generally in composition with a word denoting the purpose for which the mill is designed: as, paint - mill , quartz - mill , coffee - mill . One could see by the way he ground the coffee in the mill nailed to the wall that he was reckle of the results. W. M. Baker , New Timothy, p. 294. 3. A machine which transforms raw material by a proce other than grinding into forms fit for uses to which the raw material is unfitted. In this use also the word is generally in composition, as The Century Dictionary and Cyclopedia: The Century dictionary IMG:content-0640.png:[blocks in formation] 6. (a) A building in which grinding is done: often in composition: as, a flour- mill, water- mill, windmill, etc. (b) In metal., any establishment in which metalliferous ores are treated in the moist way, as by stamping and amalgamating, by grinding in pans, or by similar methods. Those works in which the reduction is performed by the aid of fire are usually designated smelting - works, or sometimes (especially in the case of iron) furnaces. In the manufacture of iron a mill is an establishment where the metal in the rougher form (that is, in that of blooms, slabs, rough bars, etc.) is worked up into various kinds of merchantable iron, or into those forms which are desired by the different cla es of consumers of the metal, such as rails, plates, merchant bars, and many other similar products. (c) A large building used as a factory, and occupied by machinery for the purposes of manufacture: as, a silk- mill; a cotton-mill.7. In calico-printing or bank-note engraving, a soft steel roller which receives under great pre ure an impre ed design in relief from a hardened steel engraved roll or die, and which is used in turn, after being hardened, to impart the design in intaglio to a calico-printing roll or note-printing plate.-8. [Cf. mill1, v., 1.] A snuff-box. Also mull. [Scotch.] As soon as I can find my mill , Ye'se get a snuff wi' right guid will. Picken, Poems, 17. Jamias e He plucked forth a huge horn snuff-box, or mull, as he called it, and proffered me. Scott , Rob Roy, vi. 9. A kind of screw-pre introduced during the reign of Elizabeth into England from France, and designed to supersede the manufacture of gold coins by the primitive method of striking dies with a hammer. It was introduced in 1561, discontinued in 1572, reintroduced in 1656 and 1658, and permanently adopted shortly after the restoration of Charles II. The more modern coining-pre has supplanted this machine. The mill not only struck the legend, but also raised the rim on the margin and serrated the edge. These serrations were at first straight; but, having been found easy to imitate by filing, they were made curvilinear in the reign of George II. Coining gold and silver with the mill and pre . Walpole , Anecdotes of Painting, II. iii. 10. In mining, a pa age or opening left for sending down stuff from the stopes to the level beneath.-11. [ M H T One of the most gratifying mills in the annals of the school. Dickens , Our School. Barker's mill, an ingenious machine, moved by the centrifugal force of water, invented by Dr. Barker. It consists of a vertical axis CD , moving on a pivot at D , and carrying the upper millstone m, after pa ing through an opening in the fixed millstone n. Upon this vertical axis is fixed a vertical tube TT , communicating with a horizontal tube AB , at the extremities of which, A and B , are two apertures in opposite directions. When water from the mill-course MN is introduced into the tube TT , it flows out of the apertures A and B , and by the pre ure of the water on the parts of the tube opposite the apertures the arm AB , and consequently the whole machine, is put in motion. The bridge tree ab is elevated or de D TB Barker's Mill. IMG:content-0641.png:[ocr errors] pre ed by turning the nut eat the end of the lever cb. The grain to be ground is poured into the hopper H. As modified by White law it is used in Great Britain under the name of Scotch turbine. See turbine. - Cannon-ball mill, See cannon-ball.- Chilian mill, a form of mill consisting of two heavy wheels or rollers, et parallel the horizontal shaft, and a second around a vertical axis controlling the horizontal shaft. rollers travel in vat or other suitable receptacle, and scrapers are usually provided to keep the material in the path of the wheels. This form of mill, which is of much antiquity, is now used especially for grinding oleaginous seeds, nuts, fruits, etc. See arrastre. Cone-and-cradle mill, a mill having conical muller or grinder reciprocating in a semi cylindrical concave or bed. E. H. Knight. - Crooke's mill, an occasional name for Crooke's radiometer (which see, under radiometer ). - Edge-runner mill, a mill in which the millstones grind by their peripheral surfaces instead of by their flat surfaces. The stones are generally two in number (though a single one is sometimes used), and run in a circular trough provided with a bottom of stone or of iron. The trough holds the material to be ground. The stones are pivoted to the ends of an axle like cart-wheels, and the axle is attached in the middle to a vertical shaft which rolls the stones around in the trough, 3764 thus effecting both a rolling and a rubbing action upon the material to be ground. Such mills are used for grinding flaxseed preparatory to expre ing the oil, in iron foundries for grinding sand and clay, and for other purposes. - Horizontal mill, a mill having the acting surfaces in a horizontal plane at right angles to the vertical axis of the revolving stones, as in a grain-grinding mill. Hydraulic, lapidary, etc., mill. See the adjectives.Levigating mill. See levigatel. - Mouse mill, a combined electromagnetic engine and induction electrical machine used for feeding forward the paper record-ribbon, and for electrifying the ink, in Thomson's siphon-recorder for submarine telegraphy. - Revolving mill, a form of Chilian mill in which the pan turns while the axis of the rollers does not change its position; a revolving-pan mill. - To bring grist to the mill. See grist. - To go through the mill. See go.
