WHEAT SCOURING CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 322,700,dated July 21, 1885.

Application filed April l, 1885. (No model.)

To all r11/'wm it may concern:

Be it known that l, FREDERICK DoRsEY, a

citizen of the United States, and a resident of Hagerstown, in the count'y of Tashington and State of lllaryland, have invented certain new and useful Improvements in Vheat Scouring and Cleaninglllachines, of which the following is a specification.

' Figure l is a cross sectional view on the line z z of Fig. 2. Fig. 2 is alongitudinal section on the line y g/ of Fig. l. Fig. 3 is acrosssectional view on the line z z of Fig. 2. Figs. 4 and 5 are enlarged sectional details of portions of the cylinder andbeaters, illustrating more fully their construction. y

This invention relates to machines for treating wheat, preparatory to it-s reduction into iiour, to remove the fuzzy matter from the small ends of the kernels and the germ from the larger or germ ends, and also to remove any adhering foreign matter; and it consists in the construction and combinations of parts, as hereinafter described and claimed.

In the drawings I have shown the most approved construction A being the frame, of any desired form, and arranged to support a horizontal shaft, B, in boxes or bearings o a2 on the crosstimbers A2 on the ends of the frame A.

C C2 are disks surrounding the shaftB near its ends, and forming the ends of a sheet-metal cylinder, G. This cylinder is stationary,and provided with a feed-spout, D,leading through the head disk,C, and with a discharge-chute, D?, leading from the tail-disk C2, as shown.

Attached to the shaft B inside the cylinder C3, at suitable intervals, are a series of spiders or beaters supporting arms E, across which angular beater-ribs F are attached, as shown. These beater-ribs may be made the whole length of the cylinder G3, or broken up into alternating sections of short ribs, as shown in the drawings. I lprefer the latter arrangement, as the beaters thereby act more :thoroughly upon the kernels when thus constructed. The beater-strips are formedin about equilateral triangles in crosssection, and arranged with the apex of each angle pointing in the direction in which the strips are moving, as shown. The strips F are secured to the arms E in substantially parallel lines, and with `small spaces between them,

and are formed of cast-iron,with the surfaces which act upon the grain chilled, so as to be hard enough to resist wear.

The interior Vof thecylinder Cs is lined with curved plates G, of cast-iron having chilled inner or working faces. of suitable size for convenient handling and casting, usually about six inches wide and with a curve of about seven inches radius for a machine with a twenty-inch interior diameter of cylinder; but the sizes of the plates and the radii ofthe curves may be varied to suit circumstances and the size of the machine.

The beater-strips will be about one and onehalf (l) inch wide in a twenty-inch machine, but may be enlarged or reduced as found necessary. Y

The working-surfaces of both the plates G and the beaters vF may be provided with indentations b, as shown in Figs. 4 and 5. These indentations will be quite shallow, just deep enough to receive the ends of kernels of wheat, so that as the beaters catch the wheat and throw it against theplates G the ends of the kernels will'catch in the indentations in the beaters, and the grain will be thrown against the plates G, striking the latter endwise and thus rubbing the fuzzy particles from the kernels if the small end strikes first, and breaking the germ loose from the large end if the large end strikes first. Again, the beaterstrips striking the kernels will remove the germ or fuzzy matter according to which end strikes first, and then the fuzzy matter or germ remaining will be removed when theke r nels are thrown against the plates G.

The grain is fed into the cylinderV through the spout D', and, being caught by the rapidlyrevolving beaters F, is thrown against the plates G- and gradually discharged from the spout D2.

The beater-ribs F may be set at a slight angie to the shaft B, so as to give them a screw 7 form to cause them to act as a conveyer at the same time that they act upon the wheat, land thus carry the wheat gradually through the cylinder. A very slight inclination of the beaters will be suflicient to accomplish this result, and the` speed with which the grain is to be conveyed through the machine may be regulated. by the extent of this inclination, as will be readily understood.

The plates G will be roov Some qualities of grain will require to be treated for alonger period of time than others, and this may be easily accomplished by adjusting the beaters. I have not shown any means for thus adjusting the beaters, but any approved and Well-known means may be used.

The beater-strips F will be attached to the arms E by bolts, rivets, clamps, screws, or other suitable means that will enable them to be easily removed or adj usted.

The spaces between the beater-stri ps will not be large enough to allow the grain to pass, but will be ample to permit the passage of the smaller particles of fuzzy and other matter which is rubbed from the grain.

I attain a great advantage in the form and arrangement of the beater-ribs, as the grain is caught and thrown from side to side between the ribs, and by the peculiar form of the liernels this action turns each one of them endwise and throws it in that position agai nst the plates G, and also from the angular face of one beater to the angular face of the adjoining one. Thus at some stage of its progress through the machine each end of each individual kernel will come in contact with either the beaters F or the plates G, and be relieved of the fuzzy matter and the germ, as well as all adhering foreign matter. The indentations b also add materially to the successful co-operation of the parts, as they increase the tendency of the en dwise arrangement of the kernels.

After the grain has been treated by the beaters F and the plates G it will generally be found advantageous to subject it for a brief period to the action of a brushing or rubbing machine. This brushing' is accomplished in the saine cylinder, C3, as shown, by increasing the length of the cylinder, and arranging the brushes H on the same shaft,rB, and forming the interior of that part of the'eylinder opposite the brushes with a smooth surface; or the brushing may be accomplished in a separate machine.

I do not wish to be conlined to the use of chilled east-iron for the Working-surfaces of the beaters F or plates G, as I am aware that ordinary cast-iron, or iron or wood coated with emery, or plates of prepared emery, such as emery grindingwhcels are made of, may be used to advantage.

I-Iaving thus described my invention, what I claim as new is l. A scouring-cylinder and a rotating shaft mounted within the same, in combination with sets of radial arms secured to said shaft, and series of parallel beater-ribs secured to each set of radial arms, said ribs being parallel with said rotating shaft, each' of said ribs being triangular' in cross-section and set with its apex pointing in the direction of the rotation of the shaft, substantially as set forth.

2. A scouring-cylinder having its interior surface made up of convex strips having abrasive surfaces, in combination with beater-ribs arranged to rotate within said cylinder, each of said ribs being triangular in cross-section, with its apex set pointing in the direction of the rotation ofthe ribs, and having its working or forward surfaces abraded, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

FREDERICK DORSEY.
