FLOUR-BOLTING APPARATUS.
SPECIFICATION-forming part of Letters Patent No. 448,538, dated March 17,', 1891.
Application iiled September 24, 1890. Serial No. 366.029. (No model.)
To @ZZ whom it may concern:
Be it known that l, Vieron Monia-inn, of Grafton, in the county of Walsh and State of North Dakota, have invented anew and useful Improvement in FlourBolting Apparatus, of which the following is a specification.
My invention is an improvement 1n the class of vert-ical centrifugal bolting mills or apparatus. The apparatus includes a series of horizontal revolving disks arranged one above another and a like series of revolving screens or bolts surrounding them, and also a series of annular tables, which are located at lower points than the disks and exterior-ly of the screens. The nieal or stuff to be bolted is delivered upon the upper one of the aforesaid disks and is thrown laterally against the adjacent screen. A portion passes through thelatter and is discharged from the machine, while the coarser remainder is delivered upon the next disk and subjected to the saine operation as before, and so on successively until the flour is all separated from the bran or offal, which latter is then removed by separate means. v 1.
In the accompanying drawings, Ii igure l is a vertical longitudinal section of iny improvement. Fig. 2 is a horizontal section taken o n the line 5% 2, Fig. l. Figs. 3 and a are detail perspective views. The working parts composing the bolt'ing apparatus proper are inclosed by a vertical rectangular oblong case er box vertical shaft B is arranged centrally in said casing and has fixed top and bottoni bearings a b, as shown. Rotation is imparted to this"` shaft B by means of a powendriven horizontal shaft C and initer-gearing D. A. sei-ies of horizontal circular metal disks E E'a E3, dief-in this instance six in number-are keyed on the vertical shaft B` and arranged equidistantly. It will be seen that the lowest disk E is smaller-t c., narrower than the others. They are slightly conical around the central hub c. The upper five disks have also a fiat peripheral portion, and are provided on the under side with four iianges d, which are located contiguous to the outer edge and inclined inward at an angle of about fortyive degrees. All the disks, save the upper; most one E', have also four similar flanges d arranged on the upper side adgacent to the liub c and inclined outward from the latter at an angle of forty-five degrees. Both sets of flanges d d are cast integrally with their respective disks. Their function is to serve as supports and points of attachment for the brushes or bars F, four in number, carrying brushes, the saine being arranged obliquely and bolted to the fianges d d at their respective ends. The shaft B, disks E', che., and brushes F constitute what may be termed the internal portion7 of the bolter, and of course revolve together.
I will now describe the exterior or compleinentary revolving portion of the apparatus. Y
It consists, mainly, of a series (six in number) of horizontal annular wooden plates or tables G G2, dre., and iive bolting-screens I-l", the., each of which surrounds and is arranged parallel to a set of the brushes F, so that the latter work in contact with its inner side, as shown. The screens have the forin of a transverse section of a funnel. The tables G,&c.,are arranged one above another, surrounding the shaft B, each at a point just above one of the disks E E2, tbc. They are rigidly connected by means of angular iron bais I, whose horizontal ends are bolted to the under and upper sides of adjacent tables, as shown. Thus all the upper tive tables G' G2 G4 G5 are supported on the lower one Gr, and it is in turn secured to and supported on an iron base, consisting of a frame K, whose annular gudgeon e is stepped and rotates in a corresponding socket f, formed in the horizontal bar L, that traverses and is secured to the lower portion of the casing A. The boltingcloths of the several screens l-I H2, dre., are graduated in fineness of mesh, the upper one H being the finest, the next Il.2 coarser, and so on, the lower one H5 being the coarsest. Each screen is attached at its upper edge to an annular'rib g on the, under side of a table and at its lower edge to the inner circular thickened edge g of the next lower table.
'It will be seen that the portion of the apparatus just described-to wit, the tables and screens-constitutes in effect an integral portion of the apparatus, which is supported on the frame K. It also revolves with the latter, but at a lower rate of speed than the parts supported by and revolving with the shaft B.
The said frame is rovided with a coe-@car IOO il, which meshes with a pinion M on a vertical counter-shaft B, whose gear N in turn engages the pinion O on shaft B. For the purpose of removing from the outer side of the bolting-screens H H2, ttc., the flour that may adhere to them, I arrange one brush P in each compartment and support it rigidly at the required obliquity by means of a bracket fi, attached to the inner side of the casingA. The flour falls on the tables below. A scraper Q, consisting of a thin metal plate, is attached to the lower end of each of these stationary brushes I) and works close to the table below. As will be seen, its length and arrangement are such as to move the bolted stuff that falls ou the table toward the middle of the latter, in which location it may be reached and removed by another' set of longer Scrapers Q', that cause it to diverge into one of the projecting mouths or pockets 7' of spout R, arranged at one side of the casing A. These scrapers Q are long narrow plates of thin metal and extend inward from the spout R over the platform G', &c. Their outer ends are secured to slides S, that will be presently described.
The spout R is divided into two passages ZZ by a lengthwise partition m, Figs. 2 and et. There may be one or more of these partitions, according to the number of passages required, for different grades of flour bolted by the different screens. The delivery of the bolted stuff from each table G G2, the., into the adjacentmouthjof the spout R is regulated at will by means of the aforementioned slides S, Fig. el, which have each a single notch or opening n in its lower edge, and are held vertical but are adjustable transverselyT in suitable keepers or guides on said spout. I employ a spring or other form of catch or lock o to hold the slide S fixed in the position required to deliver flour into either of the passages Z or Z in the spout.
As shown in Fig. 4.-, each scraper Q is bolted to a wooden piece p, which is hinged to a right-angular arm q, that is in turn bolted to a slide S. The Scrapers are hinged so that they may bear on the tables to the degree determined by their own gravit-y, and thus always work in close contact with the tables even if the latter should be slightly unsteady or irregular in movement.
apparatus in practical use will be apparent from the foregoing description. The material to be bolted is delivered from the upper spout R onto the upper disk E at a point near the hub c of the latter, and by centrifugal action is thrown laterally against the adjacent surrounding screen II. The finest portion, aided by the four revolving brushes F, passes through said screen and, being removed by the stationary brush P, falls upon the contiguous table G', from which it is removed by scrapers Q and Q and forced into the nearest mouth or pocket j of spout R. The portion of the material which is too coarse to pass through the screen ll escapes downward onto the next disk E2, when the operation is repeated. The tailings delivered internally from the lower screen H5 enter the cylindrical pocket r, Figs. 3 and l, of the gudgeoned frame K, and are pushed out by revolving wings T through lateral openings s onto the platform G", whence they are removed by a scraper Q into any suitable receptacle. This lowermost table GG has a less diameter than the others, as before stated, and is attached to the cylindrical side of frame l just above the gear h. It will be noted that the hub or hollow gudgeon c of said frame K is at no point in contact with shaft B. The counter-shaft B is supported by suitable means.
This form of bolting apparatus has great advantages in economy of the power required for operating it and in the fact that the meal is allowed to slide gently by its own gravity over the whole surface of the bolting-cloth, which is thus working at once, so that a large quantity of meal is passed through it in a limited space of time, and, further, in the method of removal of the bolted product in separate grades of neness.
