CHARLES RIPPIN, OF ST. LOUIS, MISSOURI.

GRAIN-SCOURER.

SPECIFICATION forming part of Letters Patent No. 451,580, dated May 5, 1891. f

Application filed February 25, 1891. Serial No. 382,693. (No model.) l

T0 @ZZ wiz/0m t may concern:

Be it known that I, CHARLES RIPPIN, of the city of St. Louis, and State of Missouri, have invented certain new and useful Improvements in Grain-Scourers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in grain-scourers; and it consists in the novel arrangement and combination of part-s, as will be more fully hereinafter described and designated in the claims.

In the drawings, Figure 1 is a vertical section of my machine, taken 0n line .e ,z of Fig. 3. Fig. 2 is a horizontal cross-section taken on the line of Fig. 1. Fig. 3 is aV vertical cross-section taken on the line y y of Fig. 2; and Fig. 4 is a cross-section of one of the spiral Win gs or vanes, showing its corrugated surface and also the small bolts or lugs which pass through the same.

Referring to the drawings, 1 indicates the case or boxing, the same being suitably mounted upon any appropriate supports.

2 and 3 indicate parallel shafts, the former of which is mounted in suitable bearings 4 in the case or boxing l. To the shafts 2 and 3, at one end, are secured in any mechanical manner gear-Wheels 5, the teeth of which mesh into each other, so that one of the said shafts Will be driven from the other, and the two shaftswill revolve in opposite directions,

and to one of the ends of one of the said shafts an ordinaryT belt-pulley 3a is adapted to be secured to receive a driving-belt from any convenient power. Encircling said shafts are spiral Wings or vanes G. One of the said spiral Wings or vanes is a right one and the other is a left spiral Wing or vane. The shafts 2 and 3 are placed at such a convenient distance apartthat the paths of the spiral Wings or vanes G will overlap each other, as indicated and shown in Figs. 2and 3. Shaft 3 is adjustable relative to shaft 2, and according t0 the peculiar nature and construction of the spiral Wings 6 When shaft 3 is adjusted approximately close to shaft 2, the Wings 6 will be brought close together. By this means it is evident that the distance between the faces of the spiral Wings or vanes 6 may be regulated, as desired,corresponding, of course,

to the size of the grain that is desired to be rubbed by them. The adjustment of shaft 3 is 'effected by thu rnb-screws 7, which thumbscrews are adapted to move the adjustable bearings S, in which said shaft3 is mounted. The bearings 8 are movable along in the case 1, as desired. The spiral Wings or vanes 6 are provided with a series of sections 9 of parallel corrugations 10, as can be seen by inspecting Fig. The sections 9 are arranged segmentally, and each of said sections is provided with parallel corrugations, as before stated, and the parallel corrugations of each section being formed at angles with the parallel corrugations of the adjacent sections.

The object of these corrugations is to elevate the grain and spread the same over the ent-ire `surface of the vanes (3 as the same revolve.

11 indicates lugs or bolts, which are suitably secured in spiral wings or vanes G. Said lugs are secured in said spiral Wings by means of small nuts ll, which are adapted to be screwed on the ends of the same. Said lugs are so arranged in the vanes that the lugs se- `cured in one spiral wing or vane Will pass without coming in contact with the lugs secured in the other wing or vane, as can be readily perceived by inspecting Fig. 2. The object of these lugs is to elevate and stir up the grain, and also to increase the friction- -surface that is brought to bear on the grain.

Said lugs should be of such a size as not to interfere With the adjusting of the spiral wings or vanes 6.

12 indicates a perforated shakeror shifting device, which is located directly beneath the extremities of the spiral Wings G, but not in such a position as to interfere With the revolving or rotating of the same. is preferably constructed by taking a piece of sheet metal and punching or stamping it full of perforations of suitable size as to admit the passage of the dust and small particles of foreign substances that have been removed from the grain.

13 indicates springs, one end of which is secured to shaker 12 and the other to the case 0r boxing or to any other part of the device as mechanical ingenuity may suggest. Said springs also have the function of supporting said shaker 12 and giving the same a vibratory motion by the agency of a disk 14, rig- Said shaker idly secured at an angle to shaft 2, which disk adapted io move between collars lf3, which collars arc rigidly secured to a horizontal moving shaft 17. By this brief explanation the operation is readily perceived. rlhe disk 14, revolving as shaft 2 does and being set at an angle on the same, will throw shaft 17 in a horizontal direction, which shaft strikes against the shaker 12, and with the agency of springs 13 will give the same a vibratory and shaking motion.

1S indicates an opening through which the grain passes from the shaker into a spout 19, which leads to anysuitablc receptacle for the cleansed grain.

2O indicatesa d ust-convcyer,which is mou ntcd in suitable bearings iii the lower part of box or casing l, the function of which is to convey the dust and small particles of foreign substances that have been removed from the grain out of the box or casing 1 into any desired receptacle through a chute or spout 2l. Said conveyer is revolved bya bel4 22, which passes over suitable belt-pulleys secured to shaft 2 and the shaft of the conveyor, as can be readily perceived in Fig. 1.

23 indicates a draft fiue oi'eonduit,onee1id of which communicates with spout 19 or the spout from which the grain passes after being cleansed, and the other end of the same communicates with a fan-box 2l, in which a fan 95 is located. Said fan is mounted on a shaft 26, which shaft has its bearings in a support 27 and also in the draft-conduit 223, as can be readily perceived in Fig. 1.

2S indicates a belt-pulley which is secured to one end of shaft 2U, and said fan 25 is rapidly turned by means of a belt Q9, which passes over belt-pulley 28 and over a belt-pulley 30, secured to shaft The function of said fan, of eourse,is well understood; but it would not be inopportuno to give a brief explanation of the same in its connection in this specificdeviee. Of course, as the grain passes from spout 10 itis bound to contain a considerable amount of dust and chatl", and a draft caused by the fan will stick or draw the same from the grain and convey it up the conduit :28. If, perchance, the influence o f the fan should attract any of the grain in its passage up the conduit 23 and across the horizontal portion of the same, the grain, being ofgreater specific gravity than the dust, will fall and may be accumulated in a hopper or receptacle 31, which is in communication with the draf t-eonduit 23. Said receptacle has secured to it a valve 32, which is held or adapted to beheld in a closed position by the suction influence of the fan; but when sufficient giain has accumulated in receptacle 31 of course suoli accumulation will open the valve 32 and permit the removal of the grain that has been accumulated in said receptacle by its own weight.

33 indicates a supplyspout through which the grain may be inserted and brought in contact with the abrasive influence of the spiral wings or varies o, and is there oijierated upon by said wings until the friction has removed the rust and foreign accumulations, such as incrustations formed upon the grain. lVlien the grain has been sufficiently operated upon so as to cleanse it, it then comes in contact with the shaker 2, and the accumulation that has been removed from the grain is sifted out of the saine and falls dowii in the bottom of the box orcasiiig 1, and is there removed, as hereinbcfore stated. 'lhc spiral wings or vanes G, while possessing the function of cleansing the grain, also convey the saine to opening 1S in the shaker. Before lthe grani is introduced, however, to the abrasive action of the spiral wings or vanes, it should .first be passed through a receiving shaker or sifter and have all the large foreign particles removed from it, such as stones, dac.
