IMPROVEMENT lN OATMEAL-MACHINES.

Specification forming part of Letters Patent No. 204.165. dated May 28, 1878; application filed March 11, 1878.

- cross-section on line m x of Fig. 3; and Fig.

5, an under View of the agitator or rubber plate.

The object of this improvementis to improve the operation of machines fr cuttng oaten grits by making its action more rapid; and its nature consists in applying a rubber over the perforated plate; in making the perforated plate stationary and reoiprocatin g twoedged cutti'ng-blades beneath it, and in the several combinatons of parts hereinafter more' fully described and claimed.

In *the drawings, A R C represent a triangular framework; D the fixed perforated plate; E, the agitator; F, the reciprocating cutter-frame; G, the two-edged cutters, made wider at the middle than at the ends to give a slight draw-cut; H, pitman; I, crank-shaft; J, the agitator-pitman; K, crank-shaft; L M, pulley orbelt wheels; N, belt; a b, guide blocks or ways, and c points or projections on the under face of the agitator.

The frame A B O is made tria-ngular in its side elevation, so as to givethe operative parts an inclined position, which position tends to facilitate the passage of the grain over the perforated plate, and to its better distribution over the whole body thereof. Between the bars or rails G the pertorated plate D is permanently fixed, as shown. This plate, in its best form, is made of steel and drilled or punched full of holes large enough to permit the passage of 'the oats and small enough to keep them in an upright or partly upright position. It will improve the action of this plate to ream the holes on the upper surface of the plate.

A cheaper plate' may be made of iron punched full of holes. The agitator E may be made of wood or cast-iron, or partly .of both; lt is 'provided with a frame or border 'coming nearly or quite in contact with the 'close contact with the perforated plate D. The fra-me F is supported in ways or guide- I blocks similar to those supporting and guiding the agitator, and it is operated bythe pitman H and crank-shaft I. i

A rapid movement is given to the knives or knit'e-frame, while a much slower one is given to the agitator. As the agitator'lifts the grain in its upward movement, time must be allowed for it to fall back; and by this movement of the grain in falling back down the incline by gravity it does not become compact, but is left measurably free to assume a suitable position for-passing into the perforations.

The knobs c may be applied to facilitate this operation or not, as nay be desired; but as one great objection to this kind of machines has been their slowness of operation it will be well to apply them. The hopper O connects with the space between the agitator and the* perforated plate, which space is open at the top or upper end,'anl the mouth of the hopper extends into this space sufficiently far to prevent its being uncovered by the receding movement of the agitator or moving cover E.

In operation, power is applied to the shaft I, as indicated by the crank or winch, and the shaft K is driven by the pnlleys M L and belt N, or by other suitable gearing.

`I have described the machine as adapted to cutting oats or making oaten grits; but it is obvious that it may be used for other grains. What I claim as new, and desire to secure by Letters Patent, is

1. The agitator or rubber E, in combinan agitatoand perforated p1ate,'in combination ton with the perforated plate D,`sbstantia lly with 'frame F amd kives G, constructed and as specified. a'ranged substantially as and for the purpose 2. The combination of the fixed plate D set forth. With the agitator E, frame F, and knves -G,

all constructed and operatin g substantially as witnesses: specified. L. EL. Bom),

3. The hopper O with space between the O W BOND DAVID OLIVER.
