IQXNO. 898,892. .Tol` Iwhom 'it may concern: Beit known that I, ANDREW HOHNER, a

Vcitizeirof the United States, residing at Ottawa, in the county of Lasalle and State of lllinois, have invented certain' new and useful Improvements in Graders and Cleaners for Grain, Beans, &c.; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and ilse the same.

This invention relates to new. and useful improvements in machines for grading and cleaning grain or the like and is, intended more especially to be employed with corn, beans, peas, etc.

Itis an object of the invention to provide a novel device of this character which will not only thoroughly clean the substance acted thereupon, but will grade the same according to the size of the particles constituting the substance.

It is also an object of the invention to )rovide a novel device of this character which can be employed in conjunction with a sheller, the combination betiveen the two being such as to have the grading or cleaning device operated from the Sheller.

Itis also an object of the invention to provide a novel device of this character comprising a rotatable cylinder, said cylinder being provided with means for partially elevating the substance, the cleaning and grading heilig attained by the agitation of the substance.

It is a still further object of the invention to rovide a novel ilece of this character which will be simple in construction, eilicient in practice and comparatively inexpensive to manufacture.

'ith the above and other objects in view the invention consists of the details of construction and in the novel arrangement and combination of parts to be hereinafter referred to.

In describing the invention in detail reference willbe had to the accompanying drawings forming part of this'speciiication wherein like characters of reference denote corresponding parts in the several views, and in which,

Figure 1 is a longitudinal sectional view illustrating the invention. Fig. 2 is a cross section looking in the direction of the head of the machine, and, Fig. 3 is a fragmentary view 1n perspective of one of the ribs ofthe Specification of Letters Patent. l l Application led March 26, 1908.

GRADER AND CLEANER FOR GRAIN, BEANS, am.'

cylinder employed in conjunction with the invention.

In the drawings 1 denotes a frame preferably rectangular, arranged on an incline and held at one end by an approximate U-shaped support 3, .the bend 4 of the seaport being above the frame. The frame is field against displacement and reinforced by the diagonal or inclined straps`5 arranged at each side of the frame, one end of each strap being secured to the frame 1 and the opposite end' to the support 3. The upper end of the frame is supported by an upright 6 arranged on each side of the frame and projecting a distance thereabovc. Each of the uprights 6 is provided With. a bracing or reinforcing strip 7 also arranged on an incline and having one end secured to the frame 1. and the opposite end secured to the u )right 6. Y

The portions of the uprights 6 above the frame 1 have secured thereto a vertically arranged frame 8 which supports a Sheller mehanisni. This sheller comprises a toothed disk 9 and is fixed to a shaft 10 mounted within a bearing 11 carried by the frame 8. This disk has secured to its outer face a hand. crank 12 by which the same is rotated.

Opposed to the toothed disk 9 to one side of it-s center is a verticall) arranged concave 13 of any desired or preferred construction.

As the specific structure of the Sheller forms no essential eatureof the invention a,

Patented sepais, 190e.` f

detail thereof is believed to be unnecessary,

except to sta-tc that the shaft projects beyond the bearing 11 and has fixed on its inner end puiiey er grooved wheel 14. It is also well to state that the frame 8, hereinbefore referred to is further supported bythe upper edge portion of a supply hopper 15 fixed to the upper portion of the uprights 6.

A portion 16 of the frame S projects downwardly and is secured to the front end of the frame 1, and mounted in this depending portion and in a bearing 17 secured to the inner surface of the bend 4 of thc support 3 approximately centrally thereof is a shaft 18. On this shaft 18 in proximity to the bearing' 17 and the hopper 15 hereinbefore referred to are spiders 19 and 20, and these spiders are connected by longitudinally disposed spaced ribs 21 held to the spiders 19 and 20 adjacent their free end portions by clamping rims 22 and 23. The' clamping rim Z2 is positioned directly beneath the pulley 14 hereinbefore referred to and is grooved for the recepl 2 f I f Y 888,892`

tion of an endless flexible member 24 which engages the rim 22 and passes over the pulley 14.

It will thus be seen that with the rotation of the shaft 10 the cylinder formed by the spiders 19 and 20 and the ribs 21 will be rotated. As thecylinder is of much greater diameter than the diameter of the pulley 14 the cylinder will, of necessity, rotate at a less speed than the speed or rotation of the pulley 14.

The s ider 19 has secured to its inner surface a lange 25 which projects outwardly beyondthe spider 19 and has its free portion 26 bent inwardly.

The hopper 15- hereinbefore referred to is provided adjacent it-s lower end with a chute 27 which projects within the flange 26 and is intended to discharge the substance falling within the hopper l5 within the cylinder. To

expedite this discharge and to permit the assage of the shaft 1,8 the innerwall'of the i opper 15 adjacent the Flange and above the chute 27 is cut away as at 28.

It might be well to state at this point that the rear wall of the hopper 15 is provided with a perforation for the passage of the shaft 18.

As shown in Fig. 1 it is to be observed that a portion or the ribs adjacent the upper end thereof are 1n close proximity as indicated at 29 and that 'for a second length they are ar.

ranged a greater distance apart as at 30 and that at a point adjacent the lower end or the spider 20 they are further spaced as at 3l.. This arrangement is provided to permit the grading of the substances discharged within the hopper. Supposing the substance to be beans, the) are fed within the cylinder through the hopper 15 and the smaller ot the beans will fall between the space 29 and drop within a discharge hopper 32 there-v notch is provided with a concave recess 36. This is to permit the ready passage of small rounded particles. It is also to be stated that each of the ribs 21 is triangular in crosssection, also disclosed in Fig. 3, and that the inclines of t-he faces extend in one direction.

The cylinder. rotates in such a direction asv to bring the base 37 of each rib in advancr af the movement of the cylinder. This will cause the ribs to elevate the grain until the rib has made about a one-half rotation when the particles will drop to the base of the cylinder.' It is this agitation that causes theparticles to pass through the various spaces.`

In order to hold the ribs against spreading intermediate theirvlength an auxiliary rinr 38 is interposed around the cylinder' at apre determined point between the rims 22 and 23. The chutes 32, 33 and 34- are each secured to the base of a body 39 having its lon` gitudinal sides inclined as shown in Fig. 2. This body may be supported beneath the cylinder in any desired manner, but it has been found best to give each free edge portion of the body an angular bend 40 to engage the frame 1. a

Attention is also directed to the .fact that the ho )per 15 projects at one side a distance beyom the Sheller mechanism hereinbefore referred to in order to permit the o'rain or other particles being inserted within thei hopper without the necessity of the same passing through the sheller mechanism.

What I claim is:

A grader of the class described, comprising a frame and a cylinder rotatably held thereby, said cylinder including a plurality of longitudinal ribs, said ribs being spaced one from the other, the space between each succeeding' rib being .increased at intervals by ste )ping one of the opposed edges of the ribs, eac i rib being triangular in cross section, the broadest portion of each rib having notches in an edge thereof, each notch being in alinement with a concave recess in a face of the rib.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses. -n ANDR E11-' HOI-INEE.
