UNITED STATES ELII'IU DOUD, OF .OSHKOSIL IVISCONSIN.
IMPROVEMENT IN GRAIN-SEPARATORS.
Specification forming part of Letters Patent No. 17,498, datedJune 9,1857.
To all whoml it may concern:
Be it known that I, ELIHU DOUD, of Oshkosh, in the county of Winnebago and State of Visconsin, have invented a new and Improved Grain-Separator; 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 longitudinal vertical section of my improvement. Fig. 2 is a front view of same.
Similar letters of reference indicate corre,
sponding parts in the two figures.
My invention consists in the employment or use of a vibrating shoe provided with screens and fitted partially within a box or chest having a 'defi ecting-plate placed in its back part, the box or chest communicating with a suction-trunk, and the whole arranged as will be hereinafter fully shown and described, wherebythe foreign substances may be readily separated from the grain and also mixed grain separated wholly or partially, as may be desired.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents a rectangular frame, which is placed on a proper base B, and C is a box or chest Which is secured in the upper part of the frame A. The bottom a of this box or chest is inclined, as shown clearly in Fig. l, and to the most elevated end of the bottom a aboard bis attached, the board being at right angles with the bottom a and extending the whole width of the box or chest.
D is a vertical trunk, the upper end of which communicates with the back part of the box or chest C. The lower end of the trunk D communicates with a fan-box E, in which a fan F is placed. The trunk D has a valve or slide G itted in it, and the'fan-shaft II has a pinion I on one of its ends, into which pinion a toothed Wheel .I gears, the wheel J being on the driving or power shaft K. The opposite end of the shaft II has a pulleyT L upon it, and a belt c passes around the pulley L, said belt also passing around a pulley d on a vertical shaft M, which. has a crank e on its upper end.
N represents a shoe, which is merely a rectA angular box having its bottom inclined downward from its inner to its outer end. At the lower end of the shoe N a screen O 1s placed,
.said screen projecting a certain dist-ance in front of the box or shoe N. At the back part of the bottom of the shoe an inclined board f is placed, said board being at the back end of the screen O. In the upper part of the shoe N a screen g is placed. This screen is also inclined and is parallel with the screen O. P is a hopper at the upper end of the shoe. The shoe N is suspended by rods h to the upper part of the frame A, the back part of the shoe Nbeing within the box or chest C, the front part being at the outer side of the box or chest, as shown clearly in Fig. l. l one side of the shoe N a rod e' is pivoted, said rod being connected to the crank e at the upper end of the shaft M.
The operation is as follows: Motion is given the shaft K in any proper manner, and the i fan E is rotated by means of lthe gearing .I I. The shaft M is rotated by means of the belt c, and a shake-motion is given the shoe N by means of the connecting-rod fzand crank e. The grain to be cleansed and separated passes into the hopper P, and as the fan F is rotated a suction is produced through the shoe N and down the trunk D, as indicated by the black arrows l. The grain passes through the screen g, while the larger foreign particles are carried by the suction over the end of the board b down the trunk D and are discharged at the bottom of the fan-box E. All light foreign substances which may pass through the screen g are also carried down the trunk D, while cockle, which will not be acted upon by the suction on account of its gravity, will pass through the inner part of the screw O and be discharged from the end of the board 71., as shown in blue. In case wheat and other grain are mixed-such as wheat and oats, for instance-the oats, which are considerably lighter than the wheat, may all be drawn through the back part of the ,shoe and be discharged at the lower end of the box or chest C, as indicated by the arrows 2,
or a portion only (the lighter portion) of the oats may be subtracted from the wheat. This may be effected by regulating the slide G, so as to increase or decrease the strength of the suction generated by the fan F. The sound grain is discharged at the outer end of the screen 0, as shown in red. The board, it Will be understood, serves as a check or guard and prevents grain having some virtue or Weight from passing into the trunk D.
By this implement it Will be seen that mixed grain-that is, those of a different specific graVity--may be separated Wholly or in part at the same time that the foreign substances are taken from it.
In many portions of the country mixed grain is ground, and this implement Will be found extremely valuablefor regulating the proportion of the different kinds of grain.
I am aware that fans have been employed in Various Ways for generating blasts, and screens have also been used and applied in various Ways in grain-separating machines. I therefore do not claim either of the parts herein described separately or in themselves considered; but,
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The vibrating shoe N, provided With the screens g O and arranged relatively with the box or chest C, and deiiecting-board b, as shown, in combination with trunk D and fan E, for the purpose set forth.
