GRADUAL-REDUCTION MACHINE FOR MANUFACTURING FLOUR.
SPECIFICATION forming part of Letters Patent N0. 297,760, dated April 29, 1884.
T0 aZZ whom it may concern.-
Be it known that 1, JOHN M. CASE, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Gradual-Reduction Machines for Manufacturing Flour, of which the following is a specification. V i
My invention relates to an improved rollermill for graduahreduction milling.
It has for its object the production of a sim' ple, cheap, and efficient roller-mill which shall perform the several reductions necessary in gradual-reduction milling, all combined in one compact and simple machine, thus enabling the miller of small means to compete with roller-mills of the most improved construction. I construct my improved roller-mill with two parallel rolls which are corrugated in difierent degrees of fineness, the coarser corrugations receiving the grain for the first reduction, and the finer corrugations for the subsequent reductions. In my improved mill I use a frame having adjustments for opening and closing the rolls, which I have fully described in another application of even date herewith, Serial No. 96,699, for Letters Patent for improvements in roller-mills. These adjustments are not represented in this application.
In the accompanying drawings, Figure 1 is a longitudinal section of the machine on the line 1 1, Fig. 3. Fig. 2 is a longitudinal section of the same on the line 2 2, Fig. 3. Fig. 3 is a transverse section thereof on the line 3 3, Figs. 2 and 4. Fig. 4 is a detached perspective view of the delivery-hoppers and pneumatic elevating-pipes hereinafter described.
My improved rolls are constructed of two sectional rollers running on horizontal shafts converging slightly from one end to the other. The ends 1 1 of these rolls for the first break are corrugated Very coarsely, ordinarily in a straight line with the roll. In the third, fourth, fifth, and sixth sections of the rolls the corrugations are preferably in spiral form. The rolls are placed wider apart at one end than at the other, and the sections gradually approach each other until close enough for the final cleaning of the bran or finishing of the through the pipe a.

reductions where they come very close to each other.
In myimproved mill the stock is first fed in at the end having the coarse corrugations It passes between the rolls at 1, and by the operation of the revolving brush 7 (shown in Figs. 2 and 3) it is brushed around in the screen 8, and the middlings made are sifted through into the hopper 9 below and taken off by the conveyer 10, while the broken wheat is brushed over the edge of-the screen into the first elevating spout 11.
In this construction of mill I use a system of air-elevators similar to that which I have described in other applications of even date herewith, Serial Nos. 96,702 and 96,703, for Letters Patent on improved process in milling The mate rial passing through the coarse corrugations after being sifted is elevated by the air-current in the pipe 11 and discharged into one of a series of settling air chambers, 17, immediately above the rolls. The material from the first break is, by the action of a corrugated feedshaft, 18, and valve 19 fed down into the'second section of the corrugated rolls, and from thence is again brushed over the wire screen below and discharged into the next air- .tube 12, and by this elevated into the next sectionof the settling-chamber 17 above, and so on. This treatment is constantly repeated until the final operation, when the bran is passed off and treated on special bran-rolls or sent to the finished feed, as it may be thought proper. I use a series of valves, 1),
one over each of the several settling-chamroll 18 from the settling-hoppers onto the sections of the rolls below.
In practical operation I adjust my improved rolls in such a manner that the end 1 simply splits the grain in halves. At'the next oper- (N07 Modl.) 2 .Sheets-Sheet 1.
