The upper end of the shaft.3.8.is rotatively mounted in abearing 44:,

whichisifastened to the frame member 7 by means. of bolts 450i; otherwise. In the lower port-ionof the. shaft 38 is preferably secured a longitudinal key member 4 6-, which should be ofzs'uflicient; length to receive in keyed rela-, tionship to ,the shaft a driving'pulley 47, adapted tobe driven from some suitable source of. power by means of a plate 48, a sprocket wheel or pulley 49 for driving the shaft 32, the shell member 23,.and' the paddle. 17. Thesprocketwheel 19 is. adapted to cooperate with wheel member 50, keyedto the shaft32,the wheel members lQ-and 50 be-.

ing operably connected by means of a chain or other suitable element 51. I I

The shaft 38 hassecurely,mounted thereon inoperative alignmentfwith theshell 23 a.

truncated cone. shaped member 52 having attached to,itsouterperiphery a suitable corrugated plate 53, which is in normal operation spaced: from and in} alignment with-the cooperating corrugated-plate 27 on, the. shell. inember23;.; Theplate 53-is detachably con-.

nected, to. the truncated; cone shaped-member 52 by, means jofisu-itable. fastening members 54 Securely attached to5 the upper surface of-the .trun,cated coneshaped member 52 isa (loyv wardlyi and outwardly inclined mein- 7 her 55, having attached thereto a plurality of distributing or supporting elements 56 for the purpose .of receivinganddistributing the rain from the sp0ut-18,,just before it-enters between the corrugated grinding members 27 .and 53.

In the, lower portion. -of. the, shell member 23 isadaptedto be located a paddle .member 57, keyed to the shaft-38by means of key 46, and adapted to revolve therewith. The pad -dle 57'is provided with a downwardly extended sleevebearingi 58, which revolvesfreely in a bracketqournal 59, fastenedto the frame or supporting plate member 5.

Froman opening 60 in the plate 5, is adapti 7 ed to extend a delivery spout 61 Y for the ground grain, which is guided into the chute onspout: 61 by means of therevolvingpaddle member 57: The driving pulley 47 sprocketwheel..i9;: and-.paddlemember 57' are positioned upon the shaft 38 in suchaalmannerthat:

the shaft 38 may have easy adjustability upwardly and downwardly as may be desired without disturbing the relative position of the driving pulley 47, sprocket wheel 49 and the paddle 57, which are retained in operative position by means of bracket members 62, 63, or otherwise, and the supporting plate for the paddle element 57.

In this construction it is readily apparent that the plate 5 functions in part as a bottom plate member for the shell 23, the lower edge of the shell being suitably located in relationship to the plate member 5 in order to allow for the desired sideway adj ustability of the shell 23, it being understood in this respect that the sideway adjustability is intended to keep shell 23 in perfect alignment with cone member 52.

In order to provide means for giving upward and downward motion to the shaft 38 and incidentally to the truncated cone member 52, it is preferred that the rod element 40 be mounted at each end in adjustable elements 66 and 67, which are arranged to receive in secured relationship therein manually operated rod members 68 and 69, provided at the lower ends with gears 70 and 71, securely keyed thereto and adapted to mesh with and cooperate with gear members 72 and 7 3, keyed to shaft 7 4, which is mounted in the supporting members 1 and 2, as disclosed at 7 5 and 7 6.

The upper ends of the rods 68 and 69 may be provided with hand wheels .77 and 78. Suitable bracket journal elements 7 9, 80, 81 and 82 are securely fastened to the frame members 1 and 2 for the purpose of maintaining the rods 68 and 69 in rotative position. By turning the wheels 77 and 78, it is apparent that the threaded portions 83 and 84 on the rods 68 and 69 will cause the rod 40 to move upward or downward as desired, thereby functioning to provide the required adjustability in the position of the corrugated plate 53, the set screws 25 and 25 also functioning to produce cooperating adjustability in order to obtain the most efficient spacing and alignment between the two corrugated surfaces 27 and 53,.

V The rod 40 is securely mounted thereon adjacent the frame supports 1 and 2. Guiding members 85 and 86 adapted to cooperate in slidable relationship with guiding rail members 87 and 88 are attached to the frame supports 1 and 2, thereby providing efficient means for positively guiding the rod 40 and the shaft 38 in its upward and downward movement whenever the hand wheels 77 and T8 are revolved.

This invention provides a vertical grinding machine particularly adapted for grinding corn, oats, rye and the like into feed for farm animals such as cattle, horses, hogs and other stock.
