GRAIN-SEPARATOR.

Specifcationforming part of Letters Patent No. 25,484, dated September 20, 1859; Reissued September 25, 1860, No. 1,045.

To all whom it may concern:

Be it known that I, J. L. BooTI-I, of Cuyahoga Falls, in the county of Summit and State of Ohio, have invented a new and Improved Grain-Separating Device; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l, is a vertical longitudinal section of my invention taken in the line m, Fig. 2. Fig. 2, is a vertical transverse section of ditto taken in the line y, y, Fig. l.

Similar letters of reference indicate corresponding parts in the two figures.

The object of thisjinvention is to separate oats and other foreign substances from small wheat after the latter has been separated from sound heavy wheat by any of the known implements in use.

This invention although capable of general application is more especially designed to be used with my improved grain-separating devices which were patented March 8th 1859, and July 12th 1859.

The within described invention consists in the employment or use of a series of inclined zig-Zag screens and boxes having a proper shake motion communicated to them and used in connect-ion with a fan and blast spout, the whole being arranged substantially as hereinafter described whereby the described end is attained.

To enable those skilled in the art to fully understand and construct my invention I will proceed to describe it.

A, represents a suitable rectangular frame in which a series of inclined screens B, are secured by elastic pendants C. The screens B, may be formed of perforated zinc or other sheet metal and placed alternately in reversed inclined positions as shown clearly in Fifr. 2. Each screen B, is placed on the top of what may be termed a shallow box C, the boxes extending the whole length of the screens and receiving what passes through them and discharging the same on the elevated ends of the screens immediately below them, openings a, being made at the lower part of each box C, to allow the escape of the contents therefrom.

The upper or most elevated part of each screen B, is provided with a smooth or unperforated surface b, said surface b, irst receiving the grain, and consequently their position is immediately below the openings a, that of the uppermost screen being immediately below the discharge orifice c, of the hopper D. The screens and boxes are secured in proper position by uprights d, which are attached to each end of them, the elastic pendants O, being secured to the lower ends of the uprights. The hopper D, is of the usual form is about equal in length to the screens B, and is secured in the upper part of the frame A.

To the lower part of the uprights d, inclined troughs E, are secured, said troughs being so placed as to catch the droppings from the screens and discharge the same at the ends of the machine.

Within 'the frame A, and directly below the lowermost box C, a fan box F, is placed, containing a fan G. The fan G, is of ordinary construction as well as the box C, and the latter communicates with an upright spout or passage H, which receives at about 'the center of its height the contents of the lowest screen B.

At one end of the frame A, there is placed a horizontal shaft I, from which the fan G, is driven by belts c, one at each end. At one end of the shaft I, there is also placed a pulley f, from which a small shaft g, is driven by a belt g. The inner end of the shaft g, has a bevel pinion h, placed on it, said' pinion gearing into a corresponding pinion z', which has a crank j, at one end from which a shake motion is given the screens and boxes by a connecting rod K.

The operation is as follows -The grain to be separated, that is to say, the small wheat mixed with oa'ts and other foreign substances which were separated from heavy wheat by my devices previously referred to or by any grain-separating device, passes into the hopper D, and through the opening c, on the uppermost screen B. The wheat and oats first strike the smooth or unperforated portion Z), of said screen, and the oats are turned fiatwise and will pass of the depressed end of the screen. Some portion of oats however will pass through but they will be discharged by the box C, on 'the next screen below and will be subjected to a like operation, a majority of the oats being separated from the wheat during each passage over the several screens, and when the grain reaches the last or lowermost screen all the oa'ts will be se arated therefrom, the lowermost screen B being a coclzle screen, the cockle being discharged from the lowermost boX C. The chess and other light impuri ties are discharged With the Wheat from the cockle screen intothe spout H, and the chess and light impurities are blown up Ward out from the spout H, the Wheat being discharged at a". The oats drop into the troughs F, and are discharged by them at each end of the machine.

This invention is now in practical operation and operates perfectly, separating oats from Wheat which Would otherwise have been ground With the Wheat into flour, for so far as I am aware no separator has been hitherto devised for separating oats from small Wheat which is about of the same specic gravity as oats, and 'therefore precludes the separating by a blast.

I do not claim separately any of the Within described parts; but,

I do claim as new and desire to secure by Letters Patent- The inclined zig-zag screens and boxes B, C, and troughs E, having a shake motion given them and used in connection with the revolving fan Gr, and spout H, the parts being arranged relatively With each other to operate as and for the purpose set forth.
