Letters Patent No. 69,545, dated October 8, 1867.
IMPROVEMENT IN GRAIN-SEPARATOR.
TO ALL WHOM I'l AY CONOERN:
Be it known that I, AMA'SA CURTIS, of Warren, in the county of Jo Daviess, and State of Illinois, have invented a new and useful Improvement in Grain-Separators; and I do hereby `declare and make known that the following is a full, clear, and exact description ofthe same, reference being had tothe accompanying drawings, and the figures and letters marked thereon, which form part of this specification.
My invention relates to that class of grain-separating machines in which the desired result is effected by the employment et a series of sieves or screens in connection with an air-blast; and it consists in a novel arrangement, whereby said 'grain-separatimr machine can be used for cleaning and separating different kinds of grain, as hereinafter set forth.
To enable those skilled in the art to understand how to construct and use my invention, I will proceed to describe the same with particularity, making reference in so doing to the aforesaid drawings, in which- Figure l represents a longitudinal vertical section of my invention showing the arrangement of sievcs in the shoe for cleaning dax-seed.
Figure 2 is a rear elevation of the said slice.
Figure 3 represents 'a section of the shoe with sieves for cleaning grass-seed.
Figure 4 a similar view of shoe arranged for separating smut and chess from wheat; and
Figure5 is a similar view of the arrangement for separating oats from wheat.
Similar letters of reference in the several figures denote the same parts of my invention.
A represents the hopper, into which the grain is put; a representing an adjustable slide, whereby the aperture at a', through which the grain passes to reach the sieves, is increased or diminished to regulate the rapidity ot' the feed according to the character or kind of the grain, as desired. B represents a bar or rod, supported in the sides of the shoe, and lying transversely upon tne upper sieve, `just below and outside ofthe hopper, having a series of arms, b b, as shown. These arms b and rod may be so arranged as to lie beneath the lower edge of the slide a, to aid in regulating the feed in ease such aid should be required, or when such grain as would not require it is being cleaned, then it may be turned back so that said fingers shall 'lie in the opposite direction. The fan in this machine is revolved over towards the top and rear of the machine, so as to give an overshot lblast through the shoes and sieves and C re resents a valve or winff passino* across the machine in the line of a l o o the air-blast, so that by turning said valve at any desired angle the direction of the blast may be governed so as to pass through the upper or lower part of the shoe, as may bc desired, which will also regulate the force of `the current, by directing it downward, and causing it to pass around inside the drum enclosing the fan. ,A
similar device, D, is arranged in the shoe, as shown, for the purpose of directing the air-blast through the upper part of the shoe or sieves. The shoe is hung upon two springs S, as clearly shown in iig. 2, the curve or bow, whereby the same is attached to the sides ofthe shoe, being stayed and kept in shape by means of the knuckles s s therein arranged, which are stiff enough to answer the desired purpose. The shoe is constructed with a close bottom marked E, provided with an opening, d, just over the upper end of the screen G, through which the grain falls upon said screen G, which is so hung as to receive both a lateral and longitudinal movement from the shaking attachment of the machine. At the rear of the shoe, and at its lower edge, arc arranged the side chutes F F, sloping each way from the centre, so that whatever may pass into said spouts through the opening e, will pass out at each side, as indicated in iig. 2.
In iig. l the arrangement in the shoe is for cleaning flax-seed; the seed and the unbroken bolls dropping through the coarse sieve H upon the sieve I below, the air-blast in the mean time blowing through the shoe and removing all light chaif and other similar substances. "lhe said sieve I has meshes which will allow the seed to drop through upon the bottom E, by which it is carried along to the opening d, over thc upper end of the screen G, upon which it falls and is carried down, as desired. At the rear end of said sieve I, and directly over the aforesaid opening c in the rear of the slice bottom E, is an opening, m, extending across the sieve, through which the unbroken bolls of seed, which cannot pass through the sieve I, enter the chutes or spouts F F, and go out at the sides of the machine, when said bolls may he broken-and passed through the machine again.
In fig. 3, which represents the arrangement for cleaning grass-seed, K represents a board which is slipped in from the rear in grooves e upon the sides of the shoe, and L a similar board, a little shorter than K, having lugs at cach corner entering said grooves, which hold said board L up on line with the grooves e, until the rear lugs come to the oblique slotsf', when said lugs pass down in said slots, bringing the board L into the position shown in said fig. 3. By this arrangement a false bottcm is produced in the shoe, bridging over the aperture d in the bottom of the shoe. and carrying the gruss-seed which passes through a {ine sieve, J, to the aperture e, through which it enters the spouts F F, and goes out at each side of the machine, where it is caught in suitable receptacles, as desired. The said sieveJ is provided at its rear end with a board, J, extending across the entire width thereof, and reaching down to the edge of the shoe bottom, as seen in said fig. 3, so as to clos( the shoe below the sieve J, and prevent the airblast from blowing the grass-seed out at the rear of the machine, the air-valves being so arranged as to allow just enough of the blast to pass out above said sieve J.
In iig. 4 is shown the arrangement for separating smut and chess from wheat; and it consists in removing all the sieves except the coarse upper one marked H, and inserting just beneath it a board, which carries everything near the rear of the machine before allowing it to drop through the space between it and the bottom, and also in covering the opening c with a removable slide, M. By this arrangement the grain is dropped from the board N so near the rear ot' the shoe that the air-blast eectuully drives all smut, dust, and chess out at the rear, while the wheat drops down .through the opening d upon the screen G, as desired.
In lig. 5 is shown the arrangement used in separating oats from wheat. Below the upper sieve II is arranged a series (one or more) of sievcs marked P, (the greater the number of said sieves the more perfect will be the result.) These sieves extend back to the rear of the shoe, as shown, and are high enough from the bottom of the shoe to allow a series of shorter sicves, R, to be arranged below, said sieves R terminating just at the opening cinto the side spouts F F, as shown, and being finer than the sieves I", although having meshes of' sullicient size to allow the kernels of wheat readily to pass through. Thus the wheat falls upon each of the sieves P successively and passes through to the sieves of the lower series R. Some oats pass out at the rear end of each of said sieves P, but many l'all upon the seves R together with the wheat. These sieves It are intended to exclude all grains of oats, and will therefore necessarily exclude some wheat, which wheat, together with the oats still remaining, passes over the ends of the sieves R through opening c into the side spouts F, where it is caught and returned to the machine as many times as may be desired.
Having now described the construction and opera-tion of my invention, I will now specify what I claim, and desire to secure by Letters Patent:
I. In combination with a shoe constructed as herein described, I claim the arrangement of the spouts F F with the opening c into the same, in the manner and for the purposes herein specified and shown.
2. I claim the opening m iu the rear end of sie've I, arranged in combination with the side spouts F, substantially in the manner and for the purposes set forth.
3. I claim the arrangement of the boards K L, in such a manner as to bridge the opening d, and discharge at opening c into side epouts F, substantially as and for the purposes described.
4. In combination with said false bottom K L, I claim the sieve J provided with the air-stop J, arranged and operating as and for the purposes specified.
5. I claim the slide M and board N, when arranged in combination with the shoe provided with a close bottom, substantially as and for the purposes described.
G. I claim the arrangement of a series of fine sieves R below the sieves I), and terminating at and in co1n binatiou with the side spouts F, substantially as and for the purposes set forth.
7. In combination with an overshot fan-blast I claim the arrangement of the regulating valve C, so as to operate in the manner herein specified.
8. I claim the arrangement of an air-blast regulator d, in combination with a grain-separator shoe provided with a close bottom, substantially as described.
9. I claim the arrangement of the reversible feed-regulator B b, in combination with the hopper of a grainsepa aa-Jr, as and for the purposes specified.
IO. I claim suspending the shoe upon springs S, in combination with knuckles s, as and for the purposes set forth.
