also in a cob-breaking attachment; also in the regulating apparatus for governing the degree of reduction, andalso in the contrivances of the various parts of the apparatus for economy of construction, all as hereinafter fully described, reference being made to the accompanying drawings, in which- Figure 1 is a vertical section of my i1nproved mill as used for grinding corn in the ear and other coarse materials, the section being inthe plane of the shaft. Fig. 2 is a front elevation of the mill with the hopper and feed apparatus used for regulatingthe feed. Fig. 3 is a front elevation of the feedshoe. Fig. 4 is a longitudinal section of part of the feedshoe. Fig. 5 is a rear elevation of the feedshoe and part of the feed-hopper and its supports. Figs. 6 and 7 are face views of the grinding-plates, respectively. Figs. 8 and 9 are details of feeding and crushing devices, on lines 00 a: and y y, respectively, Fig. 1. Fig. 10 is a side elevation of the mill, showing an elevating-discharge for delivering the ground material into bags.

I employvertical grinding-disks, as a, which is stationary, and h, which revolves and being in this example made of chilled iron or steel and in a special form of construction, which is part of my invention and will be described farther on, but so far as the rest of my invention is concerned I may use disks of any approved material or form of construction.

The disk a is bolted to the inside of ,the vertical side 0 of the inclosing case at (Z. The disk I) is similarly bolted to the rotating disk 6 at f, which is keyed fast to the shaft g, having one of its bearings in the hub 72 of the side 0 of the case and the other bearing in the hub i of the spider j which is bolted at the extremities of the arms of the spider to the side it of the case. The disk 6 has radial arms Z, reaching beyond the periphery of the grind ing-disks a short distance to serve like the the arms of the hub.

wings of a fan for discharging the ground material through the elevating-spout 9 which it is sometimes desirable to use for delivering it directly into bags; otherwise it maybe delivered downward through the spout an, according as the gates in are adjusted. The side It of the case has a large central opening to admit air for promoting a current through the discharge-spout, facilitating the discharge of the ground material, said current being generated by the rotating disks and the arms I.

The shaft carrying the rotating disk is driven by a pulley n 011 the end projecting from the side of the case to which the stationary grindingdisk a is attached, and it carries a fly-wheel 0 next to .said pulley for steady ing the motion. At the other extremity of the shaft it bears against a thrust step-plate 19, located in and adjustable along the box q, bolted to the outer end of bearing-hub i, and having its bearing-support in opposition to the shaft onthe end of the regulating-screw t, which is controlled for adjusting. the rotating grinding-disk, and also for allowing said disk to give way for relief in case of need by the nut to, lever o, and spring w, said nut being adjustable and holding the screw, and bearing against the end of box q, but not connected to it, and the lever and springpressing the screw and nut against the end of i the box, the spring having the requisite power to hold the rotating grinding-disk up to its work, but adapted to yield and allow the necessary relief to prevent breaking the grinding-disks or other parts in case a stone, piece of iron, or other like substance too hard for being ground happens to get into the mill, said spring-lever and nut then allowing the rotating disk to be forced apart from the other disk as necessary while such object is between the disks and restoring it to the normal position at once when relieved of said object. The box (1 is centered on the end of hub i by the circular recess sin the inner end of said box, and is detachably fastened thereto by the bolts as, inserted through its flange and The screwi is fitted to shift lengthwise freely through the outer end of box q, and the nut it has bearing contact only with the box. The nut has a hand-wheel y for turningit readily toregulate the grinding-disks by shifting the screw outward or allowing the screw to be forced farther in by the lever and spring, and said wheel is notched at z, and a gravity-latch a is fixed on the lever-pivot b suitably for engaging the notch and preventing the nut from working by the jar of the mill, as it might otherwise do at times when there is not much pressure on it, owing to the counteracting pressure of the material being ground on the spring w.

The lever o is pivoted at the upper end to the link .0, which is detachably connected to the standard (1 of hub 'i by its T-head e,

inserted in the bifurcated upper end of the standard under the projecting ribs f on the back of the standard, where it is securely retained by the stress of the spring in on the lever, but from which the link can be instantly detached by pulling the lower end of the lever forward and thrusting the T-head backward the width of the ribsf or a little more.

The T-head e and ribsf are beveled, as

show-n in Fig. 1, to facilitate the ready connection and disconnection of the link. This device provides a simple means of effecting the said detachable connection without fitting. Such a detachable connection is very useful, because it facilitates the adjustment of the spring w along the notched section g of the lever for varying the power of the spring, which is frequently required, the op eration being, first, pulling the lower end of the lever outward and disconnecting the link, then slackening the spring free of tension, then shifting the coil embracing the notched end of the lever along the same from one notch to another, and then again pulling out the notched end and stretching the spring so as .to pass the T-head a back over the retaining-ribs f of the standard.

The side a of the case has a central hollow conical extension h, on the outer end of which is the other bearing-hub h of the shaft and within which is a feeding and crushing space i 7, containing the feeding and crushing wingcones k and Z, both mounted on the shaft 9 and clamped to the rotating disk e by the yokes 'm, and also containing the stationary internally-fluted ring-crusher it, between which and the wings or flanges of cone l any large grains or particles are reduced preparatory to entering between the grinding-disks. Th1s ring at 1s also cone-shaped and fits in flanges that no fitting is required other than 3 the holes in the disk for the yokes and the fittingof the nuts on the yokes. The wingcone vZ has a conical central hole, which at one end centers it on the shaft and at the other end on the hub of disk 6.

The material to be ground enters space j through an opening 19 at the outer upper ex tremity of extension h from the hopper q, the quantity being regulated by a slide 5', which graduates the opening in such cases when required.

The hopper has a bottom plate t bearing on the top of the part h of the case and bolted thereto at c, said part h having a suitable flat top for seating said bottom of the hopper. The hopper also has a flange a bearing on the top of the case. Within the hopper is a rotary stirring and cob-breaking arm w, carried .by the short shaft x, located in the bearing-hub 11 and geared by the wheel 2'' and pinion a with the shaft 9. The hopper also has the cob-breaking vertical inwardly-projecting flanges b and 0 between which the rotary breaker 10 works so as to break the cobs suitably for feeding through passage 10' to the feeders and crushers in space j, effecting further reduction therein preparatory to entering between the disks for final reduction. The hopper may be attached in any approved way, and I do not go into details respecting it, but it is to be observed that it is detachably secured so that it may be removed when desired, and the ears of corn may be fed into space j by hand to be broken by the wing-cones.

For shelled corn or other fine grain that will feed regularly another hopper d is used, with a vibrating feed-shoe 6 under it, and a shaking-rod f for working it by a tappet g on the shaft g, said hopper being bolted on the brackets 71 seated on the top of the case at '6 and detachably secured by hooking under the brackets h so that said hopper can be put on and taken oif readily so as to feed into hopper g from the shoe 6 In this example I have represented the elevation of this hopper such that part of one side of hopper g has to be displaced, and with such part broken out in Fig. 2 to receive-the shoe suitably for discharging into it, but the elevation of said hopper (1 may, of course, be sufficient for the shoe to reach over the top of the 110pper g, as may be preferred; but this hopper maybe seated lower, so as to feed directly into space j through opening 19 without using the cob-breaking hopper, if desired.

The hopper d has a cast-metal bottom section 75, on which the flanges 7' are cast; also a hanger Z from the upper shoulder of which the shoe 6 is suspended by a yoke m restin gin a notch of said shoulder, as represented in Fig. 5, and through the lower end of which hanger the shoe-adjusting screw 12 works to hold the shoe in its proper position and vary the height of the opposite end for regulating the feed, the end of said screw bearing against the heel of the shoe, so as to raise or lower the other end according as the screw is screwed forward or backward through the hanger Z The check-nut o prevents the screw from working slack. Instead of the usual single feed groove or channel for dis- IIO charging asingle stream out of the mouth of the shoe, I provide two such discharge-pas- ,sages 10 by making the upturned toe g in the middle of the mouth and thus dividing said mouth. It is a means of retaining a surplus in the shoe, which, when driving by the irregular motion of a tread-power, will on undue acceleration of the motion give out an excess of feed and check the motion.

The shoe is made thin in the main portion for lightness, and the tongue g is stiffened by the inset rib F. The shaking-rod f has a spring-section f and a hook-head e on the upper end. It is sprung between two prongs d projecting from the side of the hopper and retaining the rod in position by its tension for a simple detachable connection. Said rod is connected with the shoe by the eye-loop c and extends down where the tap pet 9 takes effect to thrust it forward, and its spring-section f retracts it.

The grinding-disks are made with a series of annular flanges n and intersecting radial flanges Q2 on the confronting faces between which are recesses 10*, the annular flanges of the disks being disposed so that the circumferential flanges of one disk are intermediate to those of the other disk radially, and the stationary disk has internally-projecting teeth 00 in its eye or central opening confronting the wing-flanges of cone-crusher Z, which extends through said eye to and abuts against the face of the disk e, carrying the rotating grinding-disk b. It will be seen that the course of the material is over both the radial and circumferential flanges from the recesses of one disk into those of the other, alternately and continually crossing the cutting-edge forward and backward from the recesses of one disk to those of the other, so as to be subject to the cuts of the passing flanges in vast numbers, calculated to effect exceedingly rapid reduction and to invest the mill with great capacity.

I claim as my invention- 1. A pair of grinding-disks having the concentric circular and intersect-ingradial flanges with intermediate recesses and so arranged that the concentric circular flanges of one disk are intermediate to those of the other substantially as described.

2. The combination with a pair of vertical grinding-disks, of the laterally-extended hollow cone-receptacle for the material to be ground, the separate detachably-arranged internally-toothed crushingring located therein, said ring removably connected with its base abutting the back of the stationary disk, by the taper cone-receptacle and the rotating feeding and crushing wing-cone extendin g through the said ring substantially as described.

3. The combination with the shaft and the rotating disk, of the wing-cones centered on the shaft and clamped against the face of said disk by the yokes embracing the wings the yokes coupling the cones to the disk by the wings substantially as described.

4. The combination with the feed-hopper, of the cob-breaker consisting of the rotating arm over the feed-passage from the hopper, and the vertical flanges at the opposite sides of the lower part of the circuit of the said arm substantially as described.

5.

8. The combination of the hopper, feedshoe, the feed-shoe working rod having the spring-section sprung between the retainingprongs and detachably hooked on the upper edge of the hopper above said prongs and the tappet on the shaft substantially as described.

9. The combination with the disk-carrying shaft and the step-box, of the adjusting-screw shifting freely through said box, the adjusting-nut resting against the end of the box and the lever and spring holding the screw and nut substantially as described.

10. The combination with the lever, spring and screw, of the lever-holding link detachably connected to the standard of the shaftbearing hub by the T-head of the link and the bifurcated ribbed end of the standard, substantially as described.

11. The combination with the notched hand-wheel of the adjusting-nut, of the gravity-latch on the lever pivot engaging the notch of the hand-wheel said latch pivoted together with the lever substantially as described.
