GRAIN SEPARATOR OR SIZER.

SPECIFICATION forming part of Letters Patent No. 255,266, dated March 21, 1882.

Application filed August 29, 1881.

To all lwhom it may concern Beit known lthat I, JACOB FnLsrNG, a citizen ofthe United States, residing atVVest Granville, inthe county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Grain Separators or Sizers; and I do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to Ina-ke and use the same, reference heilig had to the accompanying drawings, and to letters and figures ot reference marked thereon,whichform a part of this specitication.

Figure l represents a side view with sid broken out to show cylinder. Fig. 2 is a crosssection; Fig. 3, a detailed view ot' cylinder. Fig. 4 is a perspective view ot' bar.

Like parts are represented by the same reference-letters throughout the several views.

The object ot' vmy invention is to provide a machine with which the large, small, and variousintermediate sizes of kernels may be separated from each other and all the kernels of the saine size deposited together by themselves, apart from those ot' different sizes. I accomplish this end by passing the grain through a long cylindrical screen, A, which is supported in an inclined position, as shown. The grain is introduced into the upper end by spout B, and is caused by the inclination of the cylinder to move gradually toward the lower end as the cylinder is revolved. The cylinder is supported upon and rigidly secured to the central shaft, O. The shaft O may be provided with a crank and the cylinder revolved by hand-power,if desired,or connected by band or gear with other motive power, as occasion requires.

D represents a universal coupling-joint, by which the central shaft, C, may be connected with a horizontal shaft, E, as shown.

The cylinder is formed in three sections,

2, 3, and 4, having` different-sized meshes. The lowest section has the largest meshes, which are adapted to allow the large kernels to pass through. The next section is a little liner. 4 is the finest, through which none but the very linest kernels can pass. Thus it is obvious that'wh-le the smallest kernels are (No model.)

screened out` by compartment 4, all the remaining grain is carried onto screen 3, when the next largest grade of kernels are screened out, and so on from one screen or section to another, until the grain reaches thelower end ofthe oylindelgwhere the largest kernels,which cannot pass through themeshes of the screen, pass out through the end ofthe cylinder. Thus the largest kernels, or No. 1 wheat, pass out through the lower end of the cylinder, while No. 2 wheat passes through screens 2, No. 3 wheat passes out through screen 3, and No. 4 wheat passes out through screen 4. The cylinder Ais connected to shaft O by arms F. As the wheat is thus passing through the cylinder it is agitated and continually carried upward against the sides of the cylinder and thrown from one side of the cylinder to the other by a series of longitudinally-arranged buckets or troughs, which are formed by the union of bars M and G, said bars being secured together at right angles to each other upon the spokes or arms F. Anarrow space intervenes between said buckets and the cylinder, through which a portion ot' the grain is permitted to escape as the buckets move upward, whereby the grain is distributed unt'ormly over the ascending side of the screen,

leaving a portion of the grain in the buckets,

which is elevated above the center of the cylinder and discharged upon the descending side of the screen, whereby the separation of the grain is accelerated.

The grain should 'traverse the entire length ofthe cylinder from the upper to the lower end upon the screen, as it is obvious that were it permitted to ow downward toward the discharge end when in said troughs or elevatorbuckets the small kernels would pass, with the lower ones, over the dividing line between the sections, from the 4finer to the coarser screens, without being screened out. To prevent the grain from tb ns descending when on the troughs the surface upon which the grain rests is formed in or provided with the series of shortinclined planesXandLtheangles of which arereversely arranged to that of the cylinder. Thus the inclination of said short planes counteracts the effect upon the grain of the inclination ot' the cylinder, and causes the grain, when elevated ICO , notching and beveling the edges of bar M, and

the angular surfacesXmay be formed either by cutting angular grooves in the bar or by securing a series of short angular blocks thereto.

Themachineisregnlated forfastor slow work by means of the adjustable standard N, upon which one end ofthe central shaft ot' said cylinder rests, and by which it is raised and lowered and the cylinder adjusted at a greater or less angle, according to the speed at which it is desired to run through the grain. For rapid work the discharge end ofthe cylinder is lowered, so that the grain by its gra'vityis caused to flow more rapidlythrough it. By raising the discharge end the opposite result is attained.

Separate receptacles H H H, for each ofthe several sized screens or apartments, are provided beneath said screens, to catch the several grades of grain as they are thus screened out. The several receptacles H are respectively provided with spouts l, to which conductors may be attached for carrying the several sizes of grain to separate receptacles therefor.

The cylinder A is provided with a case or inclosure,R, which receives all the grain which may escape through the sides of the cylinder or screens above the receptacles H, and conveys such grain back to the proper receptacles below. To facilitate in passing the grain through the meshes ot the screen and prevent the same from being obstructed, a device is provided for jarring the cylinder, consisting in the hammer J and ratchet L, which hammer is suspended above the cylinder by a pivot, K, which permits the hammer to rise and fall as therespective teeth of the ratchetpass beneath, the hammer being raised, as the cylinder revolves to the apex of one tooth, when it drops of its own gravity upon the cylinder or the next succeeding tooth, whereby the cylinder is continuously jarred and the grain and refuse substances are, as stated, prevented from being retained in the meshes of the screen. When the machine is permanently located in a mill or grain-room the driving-pulley, shaft, and spout may be supported by the Hoor, walls, or ceiling, as indicated. For portable machines a stron'g frame may be provided for supporting the several parts in their proper relative position to each other.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of screen A, shaft C, arms F, and the longitudiualllv-arranged troughs consisting of bars G and M, provided with angular surfaces X and Y, substantially as set forth.

In testimony' whereof I affix my signature in presence ot' two witnesses.
