GRINDING-MILL.

SPECIFICATION forming part of Letters Patent No. 227,465, dated May 11, 1880.

Application filed June 23, 1879.

Fig. 3, an edge view; Fig. 4, an inside view of one-half of the case; Fig. 5, a plan of the fixed rings; Figs. 6 and 7, details of the hub E; Fig. 8, a plan of the movable grindingring; Fig. 9, an edge view of the same. Fig.

' 10 is a section taken at line as of Fig. 4. Fig.

11 is a side elevation with one side of thecase and fixed ring connected therewith removed. Fig. 12 is a detail. Fig. 13 is a vertical cross section.

This invention relates to that class of grinding-mills which are designed to be operated through the action of a windmill, giving to the movable grinding-rim g an intermittent rotary movement; and it consists in the devices which are hereinafter claimed and described.

In the drawings, A represents the case, which consists of two parts, B B, which are alike and can be cast from the same pattern. The upper part of each half B. of the case 3 forms one-half of a hopper, O, and the edges of the two halves of the case do not come together except at the top. a are lugs on the inside of B B. D D are grinding-rings, oneon the inside of each half of the case. They are cast separate from the case, and are held in place by lugs 12 on the periphery, which fit between the lugs a, or some of them. These rings are not complete, a space, 8, being left for the passage of the grain, as shown at Figs. 5 and c is a bolt which passes through both parts of the case. E is a hub loose on the boltc. It is provided with two flanges, one on each side, which extend under the stationary grinding-rings D D. d are lugs on the periphery of 5 the hub E.

F is a loose grinding-ring. It has three recesses, e, in its inner edge, with which three ofthe lugs d engage. The remaining lugs d serve to carry in grain from the hopper. The hub E and loose ringF rotate together. f are ratchetteeth on the outer edge of the loose grindinggage with the teeth f. j are cog-teeth on a portion of the periphery of G. k is an arm on the ring G. It is provided with a series of holes, and to it the reciprocating rod of a windmill can be connected.

6 is a pinion on a shaft which has its bearings in the two walls m m, which extend across the hopper, the pinion being between these two walls and covered by the flanges on the upper edges thereof. The teeth j on G en gage with the pinion Z. The shaft n, on which this pinion is placed, extends into the hopper C on each side,and is provided with one or more arms, 19, which serve the purpose of agitating the grain in the hopper, which grain passes'through the passages s, and through the open space in the stationary grinding-rings, part going between the movable grinder F and one of the stationary rings, and part between the movable ring and the other stationary ring, there being two passages from the hopper leading to opposite sides of the central movable grindin gring F. The grain falls upon the periphery of the hub E, which keeps it between the rings. 4* are cars on the case to receive bolts for securing the mill to any suitable frame-work.

The loose grinding-ring F is allowed to move laterally on the lugs cl on the hub E, thereby avoiding all cramping, which is liable to occur when the grinding-rings are rigidly fastened to a shaft. The several parts are held together by the single bolt 0, which can be tightened or loosened to make the mill grind fine or coarse.

The operation is as follows: The reciprocating rod of a windmill or other power is 'to be attached to the lever la in any suitable manner, but so that the movement of such rod will give to the ring Ga vibratory movement; then, through the pawl h, which engages with the ratchet-teeth f on the movable grinding-ring F, when the lever -ring G is moved downward, or in the direction of the arrow of Fig. 2, the pawl engages with the teeth on the yielding ring and communicates motion to it. On the upward or return movement of the lever-ring the grinding-ring remains stationary. Thus the action of the mill gives to such movable grinding-ring an intermittent rotary motion. At the same time the teeth j will, through the pinion l, give a vibratory rotary motion to the agitators 1) in the hopper, preventing the grain from clogging.

I do not limit the use of my improvements to grinding-mills which are used in connection with a windmill.

The grinding-ring F can be operated by a continuous rotary motion through a pinion and gear-cogs on the periphery of the loose ring, instead of ratchet-teeth, and the agitators 19 might be operated by means of gear-cogs on the loose grinding-ring F.

What I claim as new, and desire to secure by Letters Patent, is as follows 1. The combination of the ring G, provided with a pawl, h, and teeth j, with the pinion Z, agitators p, and movable grinding-ring F, substantially as and for the purposes specified.

2. The hub provided with lugs 62 on its periphery and having flanges extending under the stationary grinding-rings D D, in combination with a movable grinding-ring, F, having recesses c on its inner edge, substantially as and for the purposes specified.

3. The case A, consisting of two like parts, B B, each provided with lugs a on the inside, in combination with two stationary detachable grinding-rings, D D, each provided with lugs 11 and central fastening and pivot bolt, 0, substantially as and for the purposes set forth.

4. The hub E and loosely-attached grindingring F, having free lateral movement between the stationary grinding-rings D D, and in combination therewith, substantially as set forth.
