IMPROVEMENT IN MIDDLINGS-PURIFIERS.
Specification forming part of Letters Patent No. 150,503, dated May 5, 1874; application filed April 11, 1874.
lTo all whom it may concern:
Be it known that I, JOHN AFFLEOQof Bur` lington, county of Des Moines and State of Iowa, have invented certain Improvements in Separators, of which the following` is a specification:
The nature of my invention relates to im`- prov-ements in devices for separating the different elements of which llou-r middlings are composed; and the invention consists in the 'arrangement of an exhaust air blast with an expanding chamber so shaped that the draft of air will separate the heavier from the lighter portions of the middlings Within said expanding ch amber,the heavyportions falling through an openin g in the bottom thereof, and the lighter passing into another chamber for further separation, from which second chamber the heavier portions are again returned to the expanding chamber, to be again acted on by the blast, while the lighter are drawn olf by the fan or exhaust; and it further consists in the arrangement of a fan or blower with the aforesaid devices, and with a discharge-pipe leading to a rotating bolt so constructed as to separate the lighter portions of the middlin gs (the fuzz) from the better portions, all as hereinafter fully described.
Figure 1 is a perspective view of a machine eflfnbodying my invention. Fig. 2 is a longitudinal vertical sectional view of the rotating bolt on the line w w of Fig. 1. Fig. Sis a vertical sectional view of Fig. 1 on the plane of the line y y; and Fig. 4 is a vertical sectional view of Fig. 3 on the plane of the line z z, and seen from the right-hand side thereof.
Letters A represent the frame for supporting the operating devices. Bis the main separating-chamber, formed, as shown plainly in the drawings, with an enlarged central portion, and contracted at its upper `and lower ends, and provided with a pipe, b, through which the middlings, in their normal condition, are fed to it in any desired manner. It is further provided with a pipe, C, leading from its open upper end to a common fau or blower, D. Itis also pierced with openings, b b', near l its lower end, and below the entrance of the pipe b, through which air is drawn toward the fan D when in operation; and its lower end has an opening, b, for purposes hereinafter described. E is a chamber with anenlarged upper end, communicating with the under side and interior of the pipe C, as shown at Fig. 3,
and its lower and contracted end open and communicating by a pipe, c, with the chamber B above the openings b b. c is avalve in through the pipe II into the end of the bolt Iy through a wire-cloth head, t', and, passing longitudinally through the bolt, is discharged .Y
through a wire-cloth head, i', at its other end, the motion of the bolting cloth on the periphery of the bolt I preventing rthe passage of the airthrough it. The bolt I is rotated by a central shaft, I', having a pulley, i, on its outer end, from which a band extends to any driving-wheel. K K K K are arms carrying reciprocating rings or knockers, 7c 7c k k, which are operated, in the usual manner, by the rotation of the bolt, to produce a jarring motion thereof. L is an opening in the frame beneath thebolt I, and L is an opening in said frame just beyond the air-discharging end, and is provided with a cut-off slide, l. M M are cutoff slides in the upper part of the chamber G,
and N is a slide controlling an opening to thc` interior thereof, for oiling, &c. The shaft d of the fan D extends downward, and carries on its lower end a pulley, d', to which motion may be communicated from any suitable shaft or pulley. l? is asieve of about No. 60 wire-cloth, and is situated below the opening b in the bottom of the chamber B, and is given a reciprocating motion by a rod, p, from a crankwheel, Q, which is operated by a pulley, It, on its shaft. T T `are projecting knobs on the case J, against which the sieve P strikes in reciprocating. U is an opening in the mainframe oor beneath the sieve'l), and V is an opening in the floor beneath the discharge end of the sieve next the case J.
. A porton of the operation of my invention is deemed obvious from the foregoing description. Its further operation is as follows: The rair entering the openings b b by the suction of the fan D will be drawn upward in a eolumn centrally through the chamber B, 'as' shown by bthe straight arrows Yat Fig. 4, and the middlings entering. the chamber I3 above the air-inlets 1; b will be caught' by the current and carried upward. The amount of draft may then be regulated bythe damper-slides M M, so as to draw the lighter portions over to the pipe C, while the heavier portions, consisting of the coarse llourand bran, will be deected outward, as shown by the curved arrows at the same figure, and falling, by their own gravity, through the eddying air at the Sides of the chamber B, will pass through theopening b to the sieve l), where the coarse Hour will be separatedA from the coarse bran, the flour falling through the sieve, and the bran shaking over its open end next the case J and through the opening V.l This bran may then be collected, constituting the .principal hulls of the body ofthe grains; and the our which has passed .through the sieve P may be reground, forming a good quality of our. The lighter portions of that which has. entered the pipe G will be carried forward to the fan D, and driven thereby through the `pipe H into the bolt I, while vthe heavier portion which entered the same pipe will drop through the chamber E andepipe c to the lower .end of the chamber B, and be again subjected to the draft, as before described, the valve c preventing draft upward through the pipe c, and only opening to allow the descent of the middlin gs therein when a suffi cient weight of them has accumulated above the valve c to open it by their downward pressure. The lighter Hour and the fuzz bran from the blossom'end of the grains, which have been forced into the bolt I,
will be driven by theblast from the pipe H toward the other endof the bolt, 7and in passi- :ing throughl the bolt," while 't"i's rotating, the knockers k will jar the fuzz loose from the boltcloth and keep it in condition for the outward passage of the flour, which they also aid in `jarring through.V The blast will at the same ent positions, but the relative arrangement must be preserved. Y
I claiml. The expanding chamber B and chamber. E, pipes G and c, and valve c', constructed:
substantially as described, and arranged ;to
operatewith thefan D and sieve P, substantially as and for the purpose specitied.
2. The chamber E, pipes C c, and valve c',
arranged to operate with the fan D and ex-1 panding chamber B, substantiallyas and for :the purpose specified.
1- 3. The bolt I, constructed' substantially asI described, and arranged to ope'ratewith the pipe H, fan D, and pipe C, substantially asA and for the purpose specified.
