GRAIN-CLEANER SPECIFICATION forming part of Letters Patent No. 705,154, dated July 22, 1902.
Application filed April 5, 1901.
.To cir/ZZ 1071.071@ it may concern/ Be it known that I, HEINRICH SOMMER- FELD, a citizen of the United States, residing at Canton, McPherson county, Kansas, have invented a new andvuseful Grain-Cleaner, of which the following is a specification.
My invention relates to improvements in machines for cleaning grain, such as wheat, oats, corn, millet, dre. and it may be said to consist in the novel arrangement and eombination of parts hereinafter described, and pointed out in the claims.
In the accompanying drawings, which illustrate the invention, Figure l represents a vertical longitudinal sectional view of my improved machine, taken on line I I of Fig. 2. Fig. 2 is an irregular sectional plan view of same, taken on line II II of Fig. l. Fig. 3 is a broken detail side elevation showing the connecting-bar secured at its opposite ends to the blower-shaft `and the rocker-shaft. Fig. 'I is abrolren inverted plan view of the hopper, showing the position of the feed cutoff thereon; and Fig. 5 is a broken vertical longitudinal sectional view ofthe upper screen forming part of my invention.
In constructing my machine I provide a rectangular frame consisting of four supporting corner-posts l, side walls 2, and transverse end pieces 3. The upper portion of the frame is provided with a hopper 4, having bottom pieces 5 6, converging toward their lower ends, between which a transverse feed-opening 7 is left/through which the grain deposited in the hopper is fed to the screens below. Said feed-opening is controlled Vby a sliding cut-off 8, consisting of a transverse strip 9, extending the length of the feedopening, and a handle IO, working through guides l1, secured to the under side of piece 5. By grasping the upper portion of the handle where it projects above the rear end of the hopper the cut-oft' may be moved up or down t0 increase or diminish the width of the feed-opening, the frictional contact between it and thebottom of the hopper serving to hold it in the position occupied when the handle is released.
To prevent the feed-opening from clicking up with straw or other debris when the machine is in operation, and also to obviate the packing and clogging of the grain at the Serial No. 54,546. (No model.)
feed-opening, I locate near the central portion of the latter a rotary agitator consisting of a fiat transverse bar l2, extending through openings in the sides of the hopper, rounded near its terminals and journaled in bearingblocks I3, secured to the outer sides of the machine. Said bar is provided with a small pulley 14C, rigidly mounted on one end, and its opposite terminal is bent to form a crank 15 for a purpose hereinafter described.
As the grain passes through the feed-opening it falls upon a coarse sieve consisting of a rectangular inner frame I6, over which is stretched a wire screen 17, and an outer frame I8, having a transverse groove 19 at its forward end to receive a transverse tongue 2O on the'adjacent end ot the inner frame, which, together with a turn-button 2l, removably secures the inner frame in position. By providing a detachable inner frame, as above described, screens of varying mesh for different grain may be substituted more economically than if the entire outer frame with its attachments had to be changed for each varietyof grain.
Vhen in its operative position, the outer frame is suspended by two arms 2l, projecting from its lower rear end, and provided with semicircular notches 22, which fit overa transverse rocker-shaft 23, and a hook 24, pivoted at its upper end to the bottom of the hopper and engaging atits lower bentenda loop 25, secured to the forward part of -the frame. Thus by disengaging the hook from the loop and the arms from the shaft the frame may be removed from the machine whenever it is necessary to exchange the inner frames.
2G indicates deflecting-strips secured to the side walls of the machine just above the screen to direct all of the falling grain from the feed-opening onto the screen and prevent any waste which might otherwise occur between the side walls and sides of the screenframe.
As the screen is moved rapidly back and forth by the rocker-shaft the lighter parti cles of grain, if it be wheat, willY be spread out and carried toward the rear portion of the screen, where it falls through onto an inclined chute 27, which discharges it to one side of the machine, while the straw andchaff are discharged from the screen at the rear end ofthemachine. Theheavierandbetterquality of grain falls through the forward portion of the upper screen upon the rear portion of a-lower screen 28, over which the best quality or No. 1 wheat passes and is discharged at the forwardend of the machine, while the second-grade wheat falls through the screen in a heap beneath the machine.
38 represents deflecting-strips secured to the side walls of the machine above the lower screen to prevent any of the grain falling from the upper screen from passing between the side walls and the sides of the lower screen.
As the grain and chaff fall from the feedopening the chaff is blown out through the rear end of the machine by an air-blast generated by a rotary blower 39, rigidly mounted upon a transverse shaft 40, journaledin bearings 41, secured to the two forward supporting-posts 1, and is provided at one end withy a small rigidly-mounted pulley 42 and has its opposite terminal bent to form a crank 43.
Blower 39 is housed in by the side walls 2 and a segmental covering 44 and when in'operation draws in air through circular openings 45 in the side walls and discharges it at a high velocity through opening 46 over the screens.
Motion is transmitted to pulley 42 by a belt 47, connecting the same to a large drive-pulley 48, rigidly mounted upon a transverse shaft 48a, journaled in bearings 49, located in the upper portions of the two rear supportingposts 1. Pulley 48 of course maybe operated byanysuitable means; butin small machines I prefer to employ a crank-handle 50 for that purpose. The agitator 1l is also rotated by a belt 47, which contacts with the upper surface of pulley 14.
Rocker-shaft 23 is bent upwardly and outwardly at its opposite ends 5l 52 and is thereby pivotally suspended from brackets 53, secured to the side walls of the machine. Terminal 51 extends above its pivotal point to receive one end of a pivotally-secured connecting-bar 54, pivotally fastened at its forward end to the crank-shaft of the blower, and tansmits motion therefrom to said rockers aft.
In cleaning verysmall grain-like millet,for instancewhich is liable to be blown away by the air-blast, I disconnect the belt and connecting-bar from the blower and substitute a short belt, (not shown,) which extends only from the drive-pulley to pulley 14, and secure the connecting-bar to crank 14 at opening 55.
For convenience in moving the machine around I provide its forward portion with two handles 56, which project forwardly from the side walls 2.
Frein the above description it will be appa-rent that I have produced a simple and durable machine and one that is thoroughly effective for the purpose intended.
Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-
