ATTACHMENT ron rAivNrNG-MILLS.

Application led September 30, 1916.

To all whom it 'may concern.'

Be it known that I, JOSEPH Women, a citizen of the United States, residing at Graceville, in the county of Bigstone and State of Minnesota, have invented new and useful Improvements in Attachments for Fanning-Mills, of which the following is aI specification.

This invention relates to attachments for fanning mills, and it has for its Vobject to produce a device or attachment of simple and ,improved construction which may be readily attached to and used in connection with a fanning mill of conventional construction for the purpose of separating wild oats from grain that has been passed through the mill. A

A further object of the invention is to produce a simple and improved attachment for separating wild oats, the same embodying in its construction a conveyer over which the grain will pass, said conveyer having an apron to which wild oats will adhere and from which the wild seed is removed by scraping, while the desired seed will roll off the conveyer to a point of deposit.

A further object of the invention is to provide simple and improved means for depositing the seeds to be cleaned on the conveyer.

With these and other ends in View which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawings,- t

Specification of Letters Patent.

Serial No. 123,126.

Fig. 5 is a transverse vertical sectional view taken on the line 55 in Fig. 1.

Corresponding parts in the several figures are denoted by like characters of reference.

The improved device in its preferred embodiment includes an elevator generally designated vby A. and two conveyers designated by B, C.

The elevator frame includes side members l5 which are suitably connected and spaced apart by cross bars 16, said side bars being provided on their inner side faces with supporting cleats 17 for the apron 1S which is guided over rollers 19, 20 at the lower and upper ends of the frame, respectively, the shaft of the upper roller being mounted on slidably supported boxes 21 which may be adjusted by means of adjusting screws 22 for the purpose of tensioning the apron. The latter, which is composed of a suitable grade of canvas, is provided at suitable intervals with slats 23, said apron being supported intermediate the rollers on the cleats 17.

The conveyers B and C are substantially of similar construction, each comprising a frame including side members 24: which are connected together and spaced apart by a presser board 25, the same being of a thickness substantially equal to the diameter of the rolls 26, 27 over which the apron 28 is guided. The lower shaft 26 of each conveyer is supported in slidable boxes 29 which are adjustable by screws 30 for the purpose of tensioning the canvas. Guide cleats 31 are provided for'the upper leads of the aprons 2S. The side members 24- of the frame C are provided with straps or arms 32 secured on the top faces thereof and slidably engaging keepers 33 on the bottom faces of the side members of the frame B., thus enabling the frames to be adjustably connected so as to vary the extent to which the apron of the frame B will overlap or overhang the apron of the frame C. The aprons of the conveyers B and C are preferably made of textile material having a somewhat fleecy surface so that awns and hairs of the wild oats will become entangled therewith and adhere thereto. Each of the frames B and C is also provided with a cross bar 31 secured on the under faces of the side members thereof and extending across the apron, said cross upper end with brackets 36 in which the shaft of the upper roller 27 of the conveyer B is supported for rotation. Braces 87 are utilized for adjustably connecting the frame of the conveyer C with the frame of the elevator A, said braces being pivotally connected with the con'veyer frame C at 38, and said braces being provided with slots 39 for the reception of clamp screws 40whereby they are adjustably connected with the elevator frame A.

The conveyer frame A is connected with the elevator frame in such a. manner that the apron of the elevator will discharge-into a hopper 41 carried by the conveyer frame B and Vwhich in turn discharges on the apron of said conveyer.

In applying the improved attachment to a fanning mill, the shaft of the lower roller 19 of the elevator A is pivotally connected with the frame of the fanning mill, a portion of which is indicated at 42, in such a position that the bottom screen 43 of the fanning mill will discharge on the elevator apron 18. The shaft of the roller 19 is provided with a sprocket wheel 44 receiving` motion from the fan shaft 45 of the mill. The upper roller 27 of the conveyer B receives motion from the shaft of the bottom roller 19 of the elevator by means of a twisted belt 46, and the bottom conveyer C receives motion from the top conveyer B through a transmission belt 47. The aprons of the ele- Copies of this patent :may be obtained for five cents each, by addressing the elevated thereby and discharged into the hopper 41, passing from thence to the top lead of the conveyer B. The good seed, being comparatively small, will roll downward over the apron until intercepted by -the shield or deflector 35, whereby it is thrown upon the apron of the conveye'r C. The Wild seeds will adhere to theaprons of the conveyers and will be scraped from the same by the cross bars 34. The good seeds will roll from the apron of the conveyer C- to a place of deposit. v

As will be seen from the foregoing description taken in connection with the drawings heretoannexed, the present invention provides a simple and effective attachment which may be readily applied to any fanning mill of conventional construction and -whereby the wild oats and similar noxious seeds may be separated from the valuable grain. Y

Having thus described they invention, what is claimed as new, isz- In a device of the class described, the combination with an elevator, of a conveyer swingingly connected therewith to receive material discharged over the elevator, said conveyer being inclined oppositely to the inclination of the elevator, keepers Yon the frame of the conveyer, and a secondconveyer having arms slidably engaging the keepers, enabling said second conveyer to be variously projected Vwith respect to the lirst mentioned conveyer, the first mentioned conveyer discharging upon the second conveyer.

In testimony whereof I affix my signature.
