CHANDOS ROY DIMlVI, 0F MUNCY, PENNSYLVANIA.

GRAIN-SCOURER.

Specification of Letters Patent.

Patented July a, role.

Application filed October 8, 1913. Serial No, 794,103,

To all whom it may concern:

Be it known that I, CHANDOS ROY DIMM, a citizen of the United States, residing at Muncy, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Grain-Scourers; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to grain scouring machines of that class in which a rotating scouring cylinder is arranged within a cylindrical casing, and the object of the present invention is to provide such machines with novel means for regulating and controlling the amount of scouring action upon the grain passing through such machine.

In the accompanying drawings I have illustrated one practical embodiment of the invention as applied to a machine of the horizontal type; and to more readily explain the invention I will describe such embodiment in detail, so that those familiar with the art will be able to understand the invention and adapt it to scouring machines of various types.

The essential features of the invention and the novel construction of the parts for which protection is desired are set forth in the claims following such description.

In said drawings-Figure l is a horizontal transverse section through a scouring machine equipped with my novel regulator. Fig. 2 is an enlarged transverse sectional view of the regulator section of the casing detached. Fig. 3 is an enlarged face view of the regulator valve. Fig. 4 is an enlarged view of part of the regulator casing section. Fig. 5 ma section on line 55, Fig; 3.

The scouring casing is usually cylindrical in cross section, and may be of any suitable construction. In the example shown it is. formed of an annular series of longitudinal vertical sections 1 which are provided with ears 1 at their meeting-edges by which they are united together by means of tie-bolts 1". One of the ordinary sections of this casing is replaced by a section 4: which contains the securing regulator that embodies the present invention and will be more fully explained hereafter. The scouring casing, in the example shown, is supported in any suitable manner, and in a preferably horizontal position, in a frame 7 of suitable construction.

Within the scouring casing there is a scouring cylinder, which may be composed of disks 2 mounted on a shaft 2* and provided with peripheral lugs or ribs 2 to which are bolted the securing blades or brushes 3, that may be of any desired construction, and are usually arranged tangential to the disk-s so that when the cylinder is rotated said blades will have a tendency to throw the gra n forclbly outward against the inner wall of the casing. The general construction and operation of the casing and cylinder are well known and need no further description herein.

The regulator section 4 above referred to .may be provided with lugs et which are wall of the casing; and, said plate 5 is pro I vided at its rear Side, near its upper edge,

with lugs .5 that are perforated for the passage of a hinge-rod 5 which rod engages corresponding lugs or openings 4? in the ends of the section 4; near the upper edge thereof, so that the regulating plate 5 can be swung by rocking said shaf so as to move the lower end or edge of the plate to or from the scouring cylinder. The inward swing of the regulating plate may be limited by suitable means, a stop-lug 5 being shown on the upper edge of the plate adapted to engage a corresponding abutment l on the adjacent side of the section 4;; see Fig, 2.

The shaft 5 extends outside of the machine and may be provided with any suitable means whereby the shaft can be rocked and locked so as to adjust and 1. .1.d the regulating plate ,5 in any desired position. As shown in the drawings a slotted sector 6 is secured to the outer end Of the shaft 5, and the slot in the sector is engagedby. a bolt 6 fastened to the frame, and provided with a wing-nut 6" by which the, sector can be clamped to hold the regulating plate in any desired position. 4

A filler 4 may be placed in the section 4, adjacent the hinged edge of the regulating plate, to prevent the grain from passing over the hinged edge of this plate into the chamzisfthe peculiar formation of the inner sur- .ratcheted,as at 5, the serrations or ratchets ber in section 4:. Any grain that might pass into this chamber behind the regulating plate can escape back into the casing at the lower edge of the section l.

One of the novel features of the invention face of said regulating plate. As shown, it is provided on its inner'face wlth trans- .verse ribs 5, which extend circumferentlally "of the scouringcasing, and are preferably inclined at an angle to the perpendicular, this inclination being, from top to bottom, toward the feed end of the machine. The sidesof these ribs 5 adjacent the feed end of the machine are preferably serrated or pointing downwardly. Preferably the in v.ner face of the regulating plate is also longitudinally serrated or'ratcheted between the ;ribs as at 5 such serrations or ratchets 5 also pointing downwardly. Said plate also preferably has at its end, adjacent the feed end of the machine, a head flange 5 which is preferably slightly deeper than the ribs 5 land will prevent the grain which may be directedforwardly by the first rib 5 from flying too far back toward the feed.

. Operation: When the machine is to be i operated the regulating valve is adjusted so that its inner surface practically forms part of the inner scouring wall of the casing, and

when the scouring cylinder is rotated the grain is thrown outwardly by the blades against the casing, and owing to the inclination of the blades the grain is gradually directed rearwardly toward the discharge end of the machine. Some grain requires more [scouring than others and where an increased scouring. efiect is desired the regulator 5 is adjusted farther inward so that the ribs 5 more fully'engage the grain and owing to their inclination such ribs will retard the. passage of grain and direct it toward 1 tirely out of the path of the grain, as indicated in dotted lines in Fig. 1, if only very I light scouring is required; or by adjusting the regulating-plate fully inward the greatest scouring effect can be produced because in such position the retaining ribs 5 have full effect uponthe grain and most effectively re tard the passage thereof through the machine. jThe ratcheted surfaces of the ribs and of the inner face of the regulating-plate enhance the. scouring effect of the regulating plate upon the grain.

When theregulating plate 5 is moved inward or toward the revolving cylinder the area or space between the'corrugated sur-' face of such plate and the cylinder is reduced so that the grain is brought into closer contact with the heaters on the cylinder and is therefore scoured much harder or more thoroughly between the scouring cylinder heaters and the longitudinal ribs on the regulating plate; and when the regulating plate is moved outwardly the scouring action is lessened. Thus by properly adjusting the regulating plate the grain may be scoured to any desired extent.

What I claim is:

1. In a grain scouring machine, the combination of a casing, an adjustable regulating plate extending longitudinally of the casing and provided on its inner face with 'ribs adapted to direct the grain toward the feed end of the machine.

2. In a grain scouring machine, the combination of a casing, a regulating plate extending longitudinally of the casing and provided on its inner face with inclined ribs adapted to direct the grain toward the feed end of the machine.

8. In a grain scourer, the combination of a casing and a scouring cylinder, an adjustable scouring regulating plate provided with ribs upon its inner face extending circumferentially of the scouring cylinder and adapted to direct the grain toward the feed end of the cylinder.

4. In a grain. scourer, the combination with a casing and a scouring cylinder, of an adjustable regulating plate provided with ribs upon its inner face extending circumferentially of the scouring cylinder and inclined toward the feed end of the machine, substantially as described.

5. In a grain scourer, the combination of a casing, a scouring cylinder, a hinged plate provided with transversely disposed ribs upon its inner face extending circumferentially of the scouring cylinder, said ribs be ing parallel and inclined to direct the grain toward the feed end of the machine.
