IMPRovED GRAIN-SEPARATOR.
Specification forming partof Letters Patent No. 48,603, dated July 4, 1865.
To all whom it may concern declare that the following is a full, clear, and
exact description thereof, which will enable? `those skilled in the art to `make and use the? same, reference being had to the accompanyi ing drawings, forming part of this specitica tion, in whichaplan or top view ot' the same.
spondin g parts.
consists in the employment or use of a series of screens and discharge-spouts arranged relatively with each other in such a manner that the grain will be subjected to repeated screenings and thoroughly cleansed from all impurities, and one kind of grain separated from another, a blast-fan being used, and also a peculiar feedingspout, in order to render the. operation perfect or complete.
A represents afra mingof rectangular form, and constructed in any proper way to support the working parts.
i B is a screen-frame, also of rectangular form, and suspended in the framingA in an inclined position, the lower end of B being attached to the bottoms of "hangers G C, which may be of metal or of a hard elastic wood-say hickory. The upper part of the frame B is attached to theupper ends of elastic standards D D, which may be constructed precisely like the hangers C C. The hangers and standards are attached to the framing by screws a, which pass through vertical slots b in the formerintc the framing, and admit of the screen-frame being adjusted in a more or less inclined position, as may be desired. (Sec Fig. 2.) The hangers and standards are so made as to yieldv or vspring in a transverse direction with the framing A.
Within the frame B thereis placed a series of screens, E, which overlap each other, as shown clearly in Fig. `1, and have their lower edges beveled, so as to incline from their ends to the centers of the lower edges, where there 'j are spouts F to` conduct the oft'al ott' from each Beit known that l, JULrUs ToMLrNsoN, ofi Newburg, in the county ofWashington and State of Wisconsin, have invented a new andj Improved 'Grain-Separator 5 and I do hereby f screen, the spouts overlapping each other as well as the screens.
The screens E may be constructed of perfo rated metal plates, and the back part of each screen, which is underneath the front part of the screen above it, is not perforated, in order that the grain may successively descend through and over each screen in the frame, the good grain-wheat, for instance-passing '1, through the screens, while the oats, sticks, and Figure l is a side sectional view of my1nvention, taken in the line .or fr, Fig. 2; Fig. 2, l
other trash pass ott through the spouts F, the
upper part of each of the latter being perfov j rated, as shown at c, in order to allow any grain Similar letters of reference indicate corre-fv which may chance `to pass into the same to pass through upon the screen below. The lower This invention relates toa new and improved l machine for separating impurities from grain, and also for separating one kind of grain from 1 another, such as oats from wheat, Src.; and it l vedge of each screen is bent upward to form a ilange or lip, d, to conduct the oats and large trash, which cannot pass through the screens, to the spouts F.
At the lower end ofthe screen-frame B there is attached a spout, G, which conducts the oats and trash oftl from one side ot' the machine,(sec more particularly Fig. 2 5) and the lower screen, E, may have a fine screen, E', underneath it, to admit of the escape of cockie and grass seed. These screens E may be placed under more or all of the screcnsE, if desired. Thelower screen conducts the grain into a blast-spout, H, the
grain falling into the lower part of a vertical portion, e, thereof, the other portion, c', being nearly horizontal and extending back to a fan case, I, containing a fan of the ordinary or any proper construction. .The blast-spout,oi' course, is equal in width to the screen-frame B, and the blast in the former drives upward all dust and light impurities, the cleansed grain being discharged at the opening f. rlhe screen-frame B has a lateral shake motion communicated to it by means ot' a bent lever, J which works on a y fulcrum-pin, g, and is operated by an eccentric, h, on a shaft, K, the former actuating a spring, L, which bears against one end of lever J ,while the other end of thelever bears against one side of the screen-frame B, the opposite side of the screen-frame having a rod, i, projecting from it at right angles, on which a spiral spring, M, is placed. rlhis spring M gives the return motion to the screen-frame and causes the screen to be operated in a uniform manner without any ununecessary jars and concussions, which have a tendency to prevent a perfect separation of the grain. I do not contne myself, however, to the precise arrangement of the parts herein shown and described, for they may be modified in various Ways and the same end obtained. I propose to have the lever J provided with an adjustablefulcrum it' astraight lever be used, and a movable eccentric if a bent lever be used, so as to vary the degree of shake ot the screen B as occasion may require. I
I would state that in certain cases ,it may be desirable to have the screens E placed in pairs in separate frames, or each placed in a separate frame operated separately, but all having the same relative position one with another, as described. This modification admits ofthe screens being moved or shaken in reverse directions, which would require a less violent or rapid shake motion and render the separating process more thorough.
I would further remark that, instead of having-the hangers C C and standards D D elastic, they may be rigid and connected to the framing A by joints. The spring M will admit of this modification.
N is a feed-spout, which is slightly inclined, and extends transversely across the elevated end ofthe screen-frame B,ashortdistance above it. The bottomj of this feed spout is perforated With holes lc at suitable distances apart, the holes gradually increasing in size from the feedend ofthe spout to its opposite end, as shown in Fig. 2. By this means the grain is discharged uniformly-over the Whole Width of the upper screen, E, as each hole is rather larger than the one immediately above it, and the increased capacity ofthe lower holes compensates for the scarcity of grain toward the lower part of the spout, the holes of `smaller diameter at the upper part of the latter preventing a too free iloW or discharge of grain at the upper part.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The securing of the pendants G C and standards D D of the screen-frame B to the framingAby means ofscrewsapassingthrough oblong vertical slots b in the pendants' and standardsand intoithe framing, to admit of the varying of the inclination of thescreen-franle, substantially as shown and described.
2. The screens E, formed With beveled lower edge, provided With aflange or lip, d, and with spouts F, and arranged or disposed Within the frame B, and with a blast-spout, G, to operate in the manner substantially as and for the purpose set forth.-
3. Theinclined feed-spout N, provided with a bottom, j, havin g perforations ot'difterent sizes, substantially as and for the purpose setforth.
4. Theintroduction of a lever, either straight or bent, between the eccentric and the sievefraine, the straight lever to have a movable fulcruin and the bentlever to be operated by a movable eccentric, substantially as and for the purpose set forth.
