CLEANER FOR CORNiOR OTlHER CEREALS.

SPECIFICATION forming part of Letters Patent No.l 629,484, dated July 25, 1899. Applicatior nled October 8, 1898. Serial No. 693,009. (No model.)

Cereals, of which the following is a specifica-- tion.

My invention relates to certain improvements in cleaners for corn and other cereals',-

and it can also be applied to any sheller or threshing-machine, although I have shown it as embodied in a cleaner apart from any shelling apparatus. f

My invention relates more particularly to that class of cleaners in which a blast-fan is combined with a suction-fan and the necessary shaking-sieves for separating the dust and dirt from the grain and carrying it to the suction-fan, whence it is discharged at any convenient point.

One feature of my invention is directed to making a portion of the floor of l the channel leading to the suctionfan from the sieves adjustable, so as to vary the angle thereof, and thus increase or diminish the space through which the blast offair must pass', thus4 en-v abling me to more perfectly control the disfv charge of the dust from the machinel and to prevent any possible ldischarge of the grain therewith.

Another feature of my invention is conisibility of any grain being carried into thel suction-fan.

Referring to the sheets of drawings, in which the same letters of reference are used to designate identical parts in all the views, Figure lisa side elevation, partly in section, of the complete machine. Fig. 2 is au end elevation' of the same on a slightly-enlarged scale and with some of the casing removed or broken away to show the interior construction. Fig. 3 is a perspective view of one of the shields. Fig.` 4 is a sectional view on the in section, on the line 5 5 of Fig. 4, with some of thecasing broken away to show the interior construction. Figs. 6 and 7 are sectional Fig. 5 is a plan view, partly views through the two sides of the machine on the line 6 G of Fig. 4, some of the parts being broken away to disclose interior portions. Figs. 8 and 9 are an inverted plan view and side elevation, respectively, of the adjustable section of the dust-chute. Fig. l0 is a sectional view through one of the bearings of said adjustable section, and Fig. l1 is an in* .verted perspective view of the casting coperatfing with said adjustable portion.

Referring to Fig. l, in which the parts of the. cleaner as hitherto constructed by me are shown in section, A represents the shaki ing-screen whose office is primarily to sepainclined plate E, which formspart'of the bottoms of the wind-channels F, which arear'- ranged on4 either side ofthe substantially circular suction-fan casing G. These channels 'F have their outer sides formed by the sides H of the principal casing of the machine, and

rate the shelled corn from the cobs, and B is the shaking-screen located beneath and co-l operating with the first-mentioned screen and lwhose function is to separate the corn from their inner sides are formed by the respective Vsides ofthe casing G for the suction-fan J.

The upper portions of .these channels are 'v formed by the plate or strip K, which extends on eitherl side of the casing Gand also entirely across the main casing of the machine` L* below the casing G; thus being substantially of a U shape. This strip K also forms the bottom of a channel which receives the air more particularly from the upper shaking screen or shoe A, the top of which channel is formed by the .bottom L of theY hopper M, `while its sides are formed by the sides H of IOO scribed are drawn into the suction-fan, so as to be discharged therefrom through the circulai` aperture O. All these parts are of the customary construction'as previously employed by me. i

Instead of making the bottom E ofthe channel F continuous clear up to the aperture N, as heretofore,l make the upper portion thereof adjustable by the employment of the section P, Whic'h is best shown in Fig. 7. This s ection consists of the main plate or body portion Q, which terminates in the rock-shaft R at its lower end and has projecting from the underside of its upperend thecurved fiange S, which has the strengthening-ribs T leading therefrom down to the shaft R. This shaft R is p'ivotally mounted at its inner end by the pintle U, which takes in the circular bearing V, formed in the segmental bearingplate W, which is secured to the side of the casing G. The plate P has the cut'away portion X to accommodate the bearing-plate W, so that a substantially air-tight junction will be formed in all positions of the section P. The other end of the shaft R passes through any desired form of a bearing in the outer casing of the machine and terminates in the rectangular portion Y, which is adapted to receive the handle Z, (see Fig. 1,) which has a latch A playing over the notched segment B', by which the shaft R is secured in any desired position of adjustment. The curved flange b coperates with the casting C', (shown in perspective in Fig. 8,) which casting is secured to the inclined board or plate D' at its lower end and has its sides in contact with the side G of the casing for the suction-fan and with the side H of the main casing. Its inner surface is curved to correspond to the curve of the flange S, which is in contact therewith, and when the section P is in its lowest position its plate Q rests on the upper edge of the casting C.

The casting C has formed on its outer side the ange E', to which is bolted a portion of one end of the shield F. (Shown in perspective in Fig. 3.) This shield F is composed of a substantially rhomboidal sheet of metal bent into the shape shown and secured by thme Vertical portion G to the side G of the casing for the suction-fan, while the portion II', which is arranged obliqnely in two planes, has its lower end in contact with the Lipper side of the inner half of the casting C. The upper end of this portion H is ,in contact with the vertical portion J ofthe casing. The portion K of the shield F is substantially vertical and has its upper end bearing against the casing J' and its lower end against the casting C' and t-he inclined piece D. A notch L is provided, through which the shaft M of the suction-fan passes. From a careful consideration of the location and form of this shield or plate F it will be seen that it covers considerably over one-half of the aperture N, lead ing to the suction-fan. The object of this Shield is to prevent any corn which may be accidentally drawn up through the channel F from entering into the suction-fan, as it is forced out to a considerable distance from the aperture N and passes about two-thirds of the length of said aperture before there is any possibility of its being drawn into the aperture by the suctionof the atmosphere. Owing to the weight of the corn as compared with the dust and chaff which the suction-fan is designed to attract, the effect of gravity will be sufficient to cause the corn to fall the remaining distance past the aperture N and into the pocket formed by the inclined strip D' and the vertical portion J of the casing, at the lower point of which pocket a door N is provided through which any corn or grain that may have accumulated may be removed. On the other hand, the dust and chaff being so light and being powerfully driven by the blast-fan C, as well as drawn by the suctionfan J, which takes in all the air started by the blast-fan C, has no difficulty in turning the corner formed by the interposition of' the shield F and then being drawn into the suction-fan, whence it is discharged through the aperture O. I provide the door N' with a setscrew N2, taking against the bottom of the plates D' and by which the door may be opened as much or as little as may be desired. The suction ofthe fan J creates a pressure against the door N', holdingit as nearly closed as the set-screw N2 will permit, and also an upward y draft through the opening, tending to carrybackany dust, while permitting the corn that may have been accidentally carried .over to escape. y

The operation of the adjustable section P is as follows: If this section is in its lowermost position, so that it practically forms a uniform continuation of the bottom E of the chute F, and the draft ofair formed by the blast-fan and the suction-fan is so strong as to carry some of the grain from the screen B up through the chute F and into the suction-Y fan, the section P will be turned up, say, to the dotted-line position of Fig. l.Land thus not only serves to lessen the channel through which the air shall pass, and thus diminish its efficiency in carrying up the heavier paie ticles, such as the grain, but the heavier particlcs instead of being bodily carried by the air usually slide up on the plates E, and thus when they come to the part P, having the greater inclination, the resistance and the attraction of gravitation become more effective to overcome the tendency of the blast to carry them upward, and they fall back.

In describing the construction I have simply described the channel on one side of the suction-fan; but it will be understood from the drawings that a similar channel is formed on the other side, while the main body of the machine from the blast-fan C up to the casin g G for the suction-fan is not separated into channels.

While I have shown my invention as etnbodied in the form which I at present consider IOO IIO

629,484 a l l f s best adapted for the purposes in hand, it will be understood that it is capable of some modiflcations, and I do not desire to be limited to the exact construction herein shown or to its employment in a cleaner alone, as it can be employed in any combined separator and cleaner.
