GRAIN SCO URER AND SEPARATOR;
SPECIFICATION forming part of Letters Patent No. 328,385, dated Qctober 13, 1885.
Application filed April 8, 1885. Serin1No.161,546. (No model.)
T0 all whom it may concern.-
Be it known that 1, Guns S. CRANSON, of Silver Creek, in the county of Chautauqua, in the State of New York, have invented new and useful Improvements in Grain Scou rers and Separators, of which the followingis a specification.
This invention relates to an improvement in that class of combined grain scourers and separators which comprise ahorizontal perforated scouring-cylinder in which the grain is scoured by arms or teeth secured to a revolving drum and wind-trunks in which the grain is freed from the light impurities.
The object of my'invention is to produce a simple and compact machine of this kind which will effect a more perfect cleaning or scouring of the grain, and a more complete separation of the detached impurities from the grain.
My invention consists, to these ends, of the improvements in the construction of the maehine,which will be hereinafter fully set forth, and pointed out in the claim.
In the accompanying drawings, consisting of two sheets, Figure 1 is a side elevation of my improved machine. Fig. 2 is a top plan view of the same. Fig. 3 is a longitudinal sectional elevation of my improved machine. Fig. 4 is a cross-section in line :0 m, Fig. 3. Fig. 5 is a cross-section, on an enlarged scale, in line y 7 Fig. 3. Fig. 6 is a sectional elevation of one end ofthe scouringdrum on an enlarged scale.
Like letters of reference refer to like parts in the several figures.
A represents the stationary main frame,and a the longitudinal shaft supported in bearings a a secured to the frame A.
B represents the scouringdrum, secured to the shaft a,and provided on its periphery with projecting arms or flights b.
0 represents the perforated scouring-cylinder surrounding the drum B, and D the tight ase which surrounds the cylinder 0. (Z is the annular air-passage formed between the cylinder O and case D.
E represents the fan-blades, secured to the shaft a near the feed end of the scouring-cylinder, and E represents the fan-case, which incloses the blades or wings E.
F represents the stationary feed hopper,
supported on an upward extension of the frame A, and G represents the shaking-shoe or separating-screen,which receives the grain fromthe feed-hopper and sifts out the sand I represents the hopper which receives the grain from the lower end of the ascending leg of the preliminary wind-trunk and conducts the same to the interior of the scouring-cylinder O, by means of a spout, 2 which extends through the air-passage (Z.
K represents the head which closes the feed end of the scouring-cylimler, and which is provided with openings L in line with the annular passage d, through which the latter communicates with the inner eye, it, of the fanease by a short cylinder or tube, 7.-:-.
L represents the head which closes the tail end of the scouring-cylinder, and which is provided with openings 1, in line with the annular passage d, through which air is drawn into said passage from the subsequent wind-trunk M, which latter is arranged at the outer side of the head L.
N is the dischargespout through. which the grain is delivered from the scouring-cylinder G into the wind-trunk M. m is an air-opening formed in the wind-trunk M, and provided with an adjustable cover, m, whereby the admission of air to the trunk M through said opening can be regulated or shut off, as may be necessary,to regulate the air-current passing through the wind-trunk M.
O is a hopper or receptacle formed at the lower side of the case D and opening into the annular air-passage (Z,for collecting the scourings or heavy material which drops out of the air-current in the passage (1. The hopper O provided with a discharge-ope ning, 0, havng a valve, 0 by which the accumulated iat-erial is discharged from time to time.
The scouring cylinder is constructed of IlIG-ClOl h woven of square or edged steel rires, whereby the grain is frequently turned n its passage through the cylinder and thorughly scoured by contact with the sharp dges of the cloth. The rotating arms or .ights I) bring the grain forcibly in contact ;'ith the wire-cloth cylinder and cause the .ernels to rub against each other, wherebythe ust, dirt, and loose outer skins of the kerels, as well as the projecting portions of the erms, are completely detached without breakng the grain. This renders the machine esecially effective for scouring buckwheat,and lso renders the machine very useful for scour- ]g and cleaning wheat and other grain.
The flights 1) upon the front portion of the rum B are inclined to feed the material to- 'ard the discharge end of the scouringcylider, while the flights upon the rear portion f the cylinder are arranged at right angles to 1e direction of rotation, whereby the grain retarded in the rear portion of the cylinder nd effectually scoured before it is discharged. he drum B is composed of sections connected y longitudinal overlapping joints 7', secured ttheir ends toheads 1-, which are fastened the shaft a. rovided with longitudinal ribs or corrugaons which increase the scouring action.
The grain, which has been freed from the oarse foreign matter by the sieve G and the ght impurities by the preliminary windrunk H, enters the scouring-cylinder C, and l scoured in the same partly by contact with 1e sharp edges of the wirecloth and partly y attrition. The scoured grain escapes from 1e cylinder 0 by the spout N, and enters the The surface of the drum B is some extent by said enlargement, while the light impurities continue in the air-current, and are carried with the same through the openings k in the head K and the tube 70 to the fan.
I do not in this application desire to claim the general features of the ,scourer and sep arator which are claimed in another application for a patent showing an upright machine and filed of even date herewith, Serial No. 161,545, but limit this application to the specific improvements in the construction of the horizontal machine which are pointed out in the claim.
I claim as my invention The combination, with the perforated horizontal scouring-cylinder C and inclosing-case D, separated by an annular space d, and the fan E, of the heads K L, provided with openings 70 Z, the wind-trunk M, arranged on the rear side of the head L and communicating with the openings Z, and the spout N, which delivers the secured grain into the wind-trunk M, substantially as set forth.
Witness my hand this 30th day of March,
GILES S. ORANSON. Witnesses:
JNo. J. BONNER, CARL F. GEYER.
