.IVLACHINE FOR SEPARATING GARLIC FROM WHEAT.

Specification of Letters Patent N0. 1,845, dated October 31, 1840.

To all whom it may concern Be it known that I, JONATHAN F. BAR- n'n'r'r, of North Granville, in the county of Washington and State of New York, have invented a new and useful Machine for Separating Garlic, Smut, and other Foreign Substances from TV heat and other Grain; and I do hereby declare that the following is a full and exact description thereof.

It is well known to those conversant with the cleaningof wheat, and other grain, that when such grain contains garlic this injurious article cannot be separated from it by sifting, or by any of the other modes of cleaning-ordinarily resorted to; it is known,

also, that the garlic is much softer than the fected by taking advantage of this differ ence in the hardness of the grain and 'of the garlic, but in a manner altogether different from the plans heretofore essayed.

The principle upon which my machine operates is that of pressure, and of the friction of the grains against each other. The two being combined in such a manner as to produce the crushing of the garlic, smut, white caps, and other foreign matter by their attrition against the grain, and not by being rubbed against anything of the nature of graters, points, or other asperities, on the interior of the machine in which the agitation is effected. The pressure may be made in various ways, as by a high column of the grain contained in a cylinder, or shaft, above the agitators, and pressing upon that portion which is subjected to friction by the agitators, or the grain may be pressed upon by a revolving, or a stationary, plate resting upon its surface; a plate of this description, and of peculiar construction is descriped in the first modification of my machine.

The grain to be cleaned is fed int-o a cylindrical vessel, within which it is subjected to pressure under, and by means of, a revolving plate, or disk, of weight sufficient to cause the garlic, and all other substances less hard than the grain itself, to be crushed by their attrition against the grain, which is kept in motion by means of projecting pieces which I call agitators, afiixed to the bottom of the cylindrical vessel, and to the under side of the revolving plate, or disk.

Figure 1, in the accompanying drawing, is a perspective view of my machine furnished with a revolving plate. A, A, is the frame-work, which may be variously constructed. B, is the cylindrical vessel into which the grain is to be fed; C, is the plate, or disk, which fits as closely as may be to, and revolves within, the cylinder. D, is a shaft, having on it a 'whirl E, by means of which the disk is made to revolve, and this it should do with a velocity of about four hundred turns in a minute; this plate may be of castiron, and it must be of sufficient lower end of which there is an'opening into the cylinder, which opening is to be governed by a sliding shutter I. Thegrain passes on to the top of the disk 0, and gets under it through an opening J, near its periphery. The disk is not actually flat on its surface near its periphery, but constitutes one turn of a volute screw, or spiral plane, which is continued on its under side, as shown in Fig. 2; which figure represents the lower side of the plate, or disk. J, is the opening through the plate, by which the grain is allowed to pass below it; and K, K, is a continuation of the spiral, or volute, of which the periphery of the disk forms the first turn. There are also on this under side, projecting pieces L, L, which I denominate agitators, and these serve to move, or agitate, the grain, while it is also agitated by the volute, and pressed by it, and by the weight of the disk. There are agitators, likewise, on the bottom of the cylindrical vessel, similar to those marked L, L, on the disk, cooperating with them in keeping the grain in continued motion; they may vary in number and form, these particulars not being matters of importance. The volute, or spiral, may be varied in form, and it may consist of a double, or of a single, thread, and the grain may pass in under the plate through more than one opening. Agitators may also be placed on the sides of the cylinder, and on the shaft, instead of on the bottom of the plate, and the bottom of the cylinder. The rubbed grain passes out through a hole in the bottom of the cylinder, which hole is governed by a sliding shutter M, Fig: 1, in the ordinary way.

Fig. 3, shows a modification of my machine in which the pressure is obtained by the weight of a column of the grain, which column may be of any height required to produce the desired elfect. In this modification, instead of using the plate O, as in that first described, I place my agitators around a revolving drum N, Fig. 3, which is contained in a cylindrical case B, similar to that shown in Fig. 1; this drum is to be five, six, or more, inches smaller than the cylinder, and around its sides there are to be set several agitators L, .L, standing with their planes obliquely to the plane of revolution, so that they may tend to press the grain downward. There are similar stationary agitators on the sides of the cylinder; and they may also be set on the lower side of the drum, and on the bottom of the cylinder, as in my first modification, and as shown in section in Fig. 4:- The cylinder B, may be made of any required height, extending, if necessary, from one floor of a mill to that next above it. In this case the feeding at the side, as in Fig. 1, is dispensed with, there being, under this modification, no use in a device of this kind.

The drum N, is represented as sustained on a shaft below the cylinder, but said shaft may extend up through the column of grain, and be driven from above. When the grain has been rubbed in this machine, and the garlic and other foreign matters broken up by the pressure and attrition, it may be cleaned by the ordinary fan.

Having thus, fully described the nature of my improvement, and shown the manner in which I carry the same into operation, .what I claim as constituting my invention, and desire to secure by Letters Patent, is-- The acting upon the grain by compression and attrition combined, with a force sufficient to crush the garlic and other foreign JONATHAN F.
