Myinvention relates, to that class of mills which employ two horizontalrunners, turning in opposite directions, between which the materialis ground or reduced. r

The object of my invention is to furnish a mill of the above character, in which thematerial will not alone be acted 'uponbythe re e fac t e unn rs, t w as e u d by ing fo c 1 46 Pie e o pa t a ai s e h p e p rt and b d ect percussion from a series of hammers, which new method of grinding, pulverizing, mixing, 0r n grat n consti u es h prime eatu ofiny invention. r v p I T a ain. s e d c nstru t the a f l the runners of saucer shape or depressed form, and of such depth that the material may .be fed to the runners in bulk, and not inva n, e a rdinar y pr c d, Qu n other words, form a cavity between the run ners, and provide the iaces, thereof with fur-1 ;when in motion. e I r rows and with hammers or projections, where- The, runners are provided with saucer-shaped by the material, as it is fedto the rapidly and or depressed faces, preferably deeper at the pp si v v ng u ner s hrown carried by centrifugal force toward their pe; ripheries, which are brought nearly together, or provided with raised rims, the material, in s r see r ound 1: ul e ize y the furrows or dress formed on the faces of the runners by the action of the material against it el r he b ectr lt llssi W ing to the action of the hammersor projections. My invention further consists in providing the peripheries of the runners with raised rings or rims, of chilled iron or steel, to retain the material between the runners until ity is ground or reduced snfliciently to. pass through the opening or space left between them. i My invention further consists in the details .of construction of'the various parts of the ap- .paratus, which will hereinafter specifically be described.

fine to pass between the opening or space left The foot of spindle B is stepped in a lifting of well known construction,

bridge-tree, B which permits of adjustment tocompensate wear, and also of flexible adjustment to relieve the step of dead friction.

In Fig. 1, I have shown the respective spindles of the runners as driven in opposite directions by gearing consisting of bevel-wheels E E, mounted upon the spindles, which mesh with similar wheels F F, mounted on the ends of shafts G G, revolved by any suitable prime mover.

The lifting bridge-tree, in which is stepped the lower end of the spindle B, also carries one end of the shaft G, so that whenever the spindle 'B is adjusted by the lifting bridgetree the shaft G follows its movement, owing to its journal-boxes being universal in a wellknown way, whereby the gearing always continues in mesh; butany other mode of continuing the gearing in mesh may be employed.

Thedriving-spindleB is hollow, and leads directly to the cavity between the runners, by

which means I am enabled to feed the material in bulk through a suitable dead-eye suspended directly over and passing through the hollow shaft. o

In Fig. 2,'I have shown a method'of driving the apparatus by belting, which will be readily understood by an inspection of that figure, a

lifting bridge-tree being shown both for the, spindle of the lower runner and for the driv ing-shaft H.

In Fig. 4 the runners are shown as provided with false wearing-plates and raised'rings or rims, the hammers being omitted.

In Fig. 5 the hammers are shown as set in the rims and projecting into the cavity, in-

. stead of being located entirely within the raised rims, as in Fig. 1. I

In F g. 6 the dress or furrows upon the-faces of the runners is omitted, and spikes or projections formed thereon instead, which construction may be desirable in mixing certain articles, and for other purposes.

In Fig. 7, I have shown runners of an undulatory form, which increases the frictional surface, and is adapted for such purposes as cleaning or polishing materials, and cork or other soft'substance may be inserted in the peripheries of the runners in lieu; of the steel or hardened rims or rings.

, Various other forms of runners will readily suggest themselves as peculiarly adapted for particular .materials and purposes to those skilled in the art.

The operation of my improved apparatus is as follows: The material is fed through the hollow shaft to the cavity between the runners, which are rapidly revolved in opposite directions, and, falling upon the distributing-surface formed upon the center of the lower runner, is carried by centrifugal force, generated by the rotation of the runners, outward toward their peripheries. The material in its passage is acted upon by the dress or furrows, and, being in bulk, is forced one piece or part against another piece or part, which greatly aids in its reduction, and when it reaches the hammers or projections the reduction is still further effected by direct percussion. The material is retained between the runners by the raised rings or rims, which form, in reality, saucers of the runners, until reduced, ground, disintegrated, or mixed sufficiently fine to pass between the rims, the facesofwhich may also act upon the material before its final exit.

I claim as of my own invention- 1. The saucershaped runner, constructed substantially as hereinbefore set forth, having its concave face provided with a suitable dress or furrows, with a series of hammers, and with a raised ring or rim on its periphery.

2. The combination, substantially as hereinbefore set forth, of horizontal oppositely-revolvin g concave or saucer-shaped runners, haw

ing raised rims or flanges, and arranged with their concave faces opposite each other, whereby material may be fed in bulk between the runners, and disintegrated by the attrition of one particle uponanother, and by the action of the runners, and retained between them until sufficiently reduced to pass between the rims.

3. In combination,saucer-shaped horizontal oppositely-revolvin g runners, having their concave faces opposite each other, and being provided with furrows,hammers, and raised rims, substantially as described, whereby the mate rial fed to the runners is disintegrated by the attrition of one particle upon another, by the furrows and hammers, and retained by the rims until thoroughly pulverized.

, 4. The combination, substantially as hereinbefore set forth, of horizontal saucer-shaped oppositely-revolvin g runners, the hollow upper spindle through which the feed passes, the lower spindle stepped upon a bridge-tree, and the driving-gearing, for the purposes specified. In testimony whereof I have hereunto subscribed my name. V
