GRAlN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 359,569, dated March 15, 1887.

Application filed April 22, 1886. Serial No. 199,780.

To aZZ whom it may concern:

Be it known that I, NOAH HoLLIuGER,acitizen of the United States, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Grain-Separators; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. 1

This invention relates to separators provided with shaking-screens.

This invention consists in the novel construction and combination of parts hereinafter fully described and claimed, by which the rubbish is separated from the grain, and by which the small and imperfect grains are re moved when the grain is to be used for seed.

In the drawings, Figure 1 is a perspective view of the separator. Fig. 2 is a vertical longitudinal section taken on the line 00 a: in Fig, 3. Fig. 3 is a rear end View of the separator.

A is the casing of the machine, consisting of uprights and cross-pieces framed together and boarded over'in the usual manner.

A are handles secured to the casing, by which the machine may be lifted about from place to place.

13 is a hopper at the upper part of the front of the machine. The hopper is provided with a sliding gate, 1), for regulating the discharge of grainvand causing the grain to flow in an even stream. This sliding gate is provided with guides b, and may be adjusted with great exactness by means of the screw b" and handle b 0 is the fan, of ordinary construction, journaled in the casing of the machine. A pulley, c, is secured upon the end of the fan-shaft 0, outside the said casing, for driving the fan.

D is a crank-shaft journaled in bearings secured to the front end of the machine, and provided with a pulley, d, at one end for driving the fan by means of the belt d, which passes over the pulley c on the fan-shaft.

A are holes in the side of the machine-casing, through which the supply of air for the fan is drawn.

(N0 model.)

A is a guard-plate for directing the air from the fan to the rearpart of the machine.

A crank, (P, is fermed in the crank-shaft D.

This crank actuates the screen-shoe by means of the pitman E. One end of the said pitman engages with the crank and the other end is pivoted to thebottom of the shoe. A spur-pinion, d is secured on the other end of shaft D for rotating it. p E is a spur-wheel secured upon a shaft, e, which is journaled in suitable bearings outside the casing of the machine, and is provided with the handle 6. The wheel E gears into the pinion d, so that the said crank and fan shafts may be rotated by turning the handle. F is a shaking -shoe for supporting the screens. This shoe is supported from the machine-casing by means of the rods f, which are pivoted to it and to the said casing.

G is the upper wire screen, supported in the shaking-shoe F. The screen G is made with about nine wires to the inch, so that allthe dirt and small grains of wheat may fall through it.

G is the lower wire screen, supported in the shaking-shoe F underneath the screen G. The screen G is made with about twelvewires to the inch, so that the dirt only can pass through it.

G is the bottom of the shoe, upon which the dirt falls after passing through the screen G. Both screens and the shoe-bottom are inclined, so that the grain and dirt may slide off them when the shoe is shaken.

H is a chute secured to the shoe F, for receiving the dirt which slides off the bottom of the shoe. I is a chute, also secured to the shoe, for receiving the small grains which cannot pass through the screen G. Both chutes H and I are inclined, and their ends project through a hole, a, in the side of the casing, so that the dirt and small grains may be dis charged clear of the machine.

J is a screen which forms a continuation of the upper screen, G. This screen J is made in two parts, of which the part j, which comes next to the screen G, is furnished with about six wires to the inch. 'The remaining part of the screen J consists of a perforated plate, j. The grain falls through the sieve j and through the plate j, while any sticks or straws which may be mixed with it are retained.

K is the equalizer for collecting, equalizing, and centralizing the flow of the grain with re spect to the fan-blast. The equalizer consists of a curved plate of sheet metal placed underneath the screen J to catch the wheat as it falls through it. A narrow slit, 7c, is cut lengthwise in the bottom of the equalizer. The wheat falls through this slit in an equal and steady stream, which is acted on by the blast from the fan, which blows out all the light substances which may have passed through the screens. From the equalizer the wheat falls upon the screen L, secured in the shaking-shoe I". The motion of the screen spreads the grain over its surface, so that each particle is exposed to the action of the blast. The central delivery from the equalizer prevents the grain from accumulating toward the sides of the screen and leaves a space on each side of the falling grain for the light substances to be blown out of the machine. The screen L is reversely inclined, and is made with about nine wires to the inch, so that any small grains still remaining in the wheat may fall through it and be caught in the box Z at the bottom of the machine. The clean seed-wheat passes over the screen L into the spout llLwhieh discharges it through the side of the machine into a measure or other convenient receptacle. \Vhen the wheat isnot to be used for seed, it

is not necessary to separate the smaller grains from it. In this case the screens G and L, which have about nine wires to the inch, are taken out altogether. The screen G is also removed, and it or any similar sieve having about twelve wires to the inch is placed in the position formerly occupied by the screen G, so that the wheat may pass over it and onto the screen J, as previously described. lhe dirt passes through the screen G and is discharged by the chute H, the same as if its position had not been altered.

Having thus described my invention. what I claim as new, and desire to secure by Letters Patent, is-

In a separator, the combination of a shaking-shoe, screens for the grain supported in said shoe, a curved equalizer supported in the shoe and having a narrow openinglengthwise of the machine, and a rex olving fan for cleaning the grain.

In testimony whereofI affix my signature in presence of two witnesses.

NOAH HOLLINGER.
