CORMACK @L WALKER.
Grain Separator.
Patented Oct. 14-, 1856.
Lgf
JOEL W. CORMAOK AND F. C. WALKER, OF QUINOY, ILLINOIS.
GRAIN-SEPARATOR.
Specification of Letters Patent No. 15,879, dated October 14, 1856.
To all whom t may concern.'
Be it known that we, JOEL W. CORMACK and F. C. IVALKER, `both of Quincy, Adams county, and State of Illinois, have inventeda new and Improved Grain-Separator; and we do .hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.
In the drawings similar letters refer to like parts.
Figure l is a vertical section. Fig. 2 is the fan chamber with the cover removed. Fig. 3 is an inverted view of the conical end of air chamber or tube.
To enable others skilled in the art to make and use our invention we will proceed to describe its construction and operation.
In Fig. l A is the fan chamber-a, the
shaft of the fanb, the pulley for driving `the fan o-n shaft a., 0 the fan-rl, bearing for the journal of shaft a to run in-e the lower bearing of shaft a, and running across the air passage or throat, f, the throat, g, the check valve for increasing or decreasing the size of the throat- 13, the cheat box-h, z., pipes for the discharge of the cheat-C, the suction air chamber, or trunk-.D, the hopper, and spout, to receive the grain, to convey it to the air chamber-,Athe flanges at the bottom of the air chamber, for giving to the current of ascending air the whirlwind blastc, the funnel, or cone shaped mouth E, the hopper to receive the grain, and convey it through the spout, from the machine-F, the frame to support the machine. j
In Fig. 2, A is the fan chamber-c, the fanZ the exit for the air, and to carry off the straw, dust, and dirt.
In Fig. 3, 7c is the funnel invertedz', the flanges on the lower end of the air chamber.
In the operation of our invention, the grain is placed in themachine, at the hopper D and passes through the spout into the air chamber.` The fan beingput in motion by any power used, and as the fan revolves, a suction is created causing the airfto pass up through the air chamber, as the air is j distance above it.
forced into the air tubes it passes between the ianges z' in the funnel k; and as the air passes in between these flanges there is given to it a spiral motion as shown by the crossed arrows. By the arrangement of the spiral draft we are enabled to have a greater length of draft in the tube of a given length, for the purpose of operating on the parts to be carried off. It will be found that in the wheat, many pieces of broken straw exist, these are mostly broken at the joint, this part of the straw is smaller than it is at the other end, and the joint end is heaviest, as the current of air in a straightdraft operates on the straw it is lifted vertically and the resistance being always on the small end it is often, as heavy as the grain, and will pass out with it. But by means of the spiral `motion in our air chamber, we cause the straws to take a horizontal position, and by this means present a greater surface for the blast to operate on, and we are thus enabled to carry it out of the grain.
It will be seen that the cheat boX into which the air tube passes has its bottom concave with a rim around the walls of the air tube while the air tube passes a short In ascending the air tube as stated, the air has a spiral motion but as soon as it enters the cheat box this spiral current is broken which causes the cheat and oockle, &c. to fall into the cheat box as seen by the arrows m, m, and is conveyed off by means of the pipes L, z. The valves 0 in the pipes 7L are for letting the cheat and cockle out of the cheat boX, when desired. The current nowbecomes vertical following the direction of the arrows n, n, carrying with it the straw and dust which are passed off at the spout, or exit Z. The check valve g, at the bottom of the fan chamber is slid in when I intend to decrease the draft and drawn out for the increase of the same.
We may find it convenient in some instances to place the fan chamber horizontal instead of vertical as shown in the drawings.
The flanges 'i may be differently constructed as various forms will produce the same result. f
Having thus fully described o-ur invention What We Claim as new, and Wish to se- Whirlwind blast in a grain separator as herecure by Letters Patent is: b h h n described.
