Letters Patent No. 91,612, dated June 22, 1869.
IMPROVEMENT m FLOUR-MILLS.
The Schedule referred to in these Letters Patent and making part ofthe same.
Be it known that I, HEN-RY CUTLER, of Ashland, in the county of Middlesex, and State of Massachusetts, have invented certain Improvements in Grinding, Grading, and Drying Grain and Meal; and do hereby declare the following to be a clear and exact description thereof, reference being bad to the accompanying drawings, in which-- Figure 1 is a transverse sectional view of my improvements.
Figure 2 is a plan view. The object-of my invention is to produce mcans by which a uniform grading of meal may be obtained, to secure the proper drying or cooling of meal after it leaves the mill, to availmyself of the heat of the mill itself, and to conveniently regrind the tailings without clogging the mill, or suspending the work on whole grain.
The nature of myinvention consists in employing an elevator for receiving the meal after it comes from the mill, passing the mealovcr the proper sieves, carrying the tailings back to the mill in such manner as to regulate a uniform supply of grain and tailings to the mill; also, in creating a fall for the gradedftneal,
through a dry atmosphere, regulated, as desired, by
current-s or blasts of warm air.
By the use of my invention, I can. work on a new crop of grain as soon as harvested, while,.the old way, several weeks pr months must elapse before the grain is sufficiently seasoned to allow of putting up into bags or barrels.
I also secure a perfect grading of meal, so that a lot willbe of uniform fineness throughout.
In the'drawings- A is a mill.
B, the hopper.
S is a shoe or feeder, under the hopper.
D is an elevator, carryingmeal from the mill up to the top of box or chamber E.
F is a sieve, running nearlythe whole length of chamber E.
- Elevator D is actuated by-power at b.
To the shaft a is attached, by cam, arm G, and the cam-movement givesa vibrating motion to sieve F.
m m are straps, which hold .sieve F in proper positiou. These straps are hung upon pivots at n.
H is a box, at the end of sieve, and into this box fall all the tailings from the meal.
All themeal of a proper fineness passes through of twenty feet, when it is received in the meal-box or chest.
The tailings pass into box H, and are carried by pipe I? to the mill again, when, in connection with new grain, they are reground.
The operation of my invention is simple and satisfactory. p
The grainis ground, as usual. The meal is carried by elevator D to top of chamber E, and deposited upon sieve F. This sieve is: of any desired fineness. All the meal that is of sutiicient fineness passes through sieve F, and falls at the bottom of chamber E; and
this fall is essential, for the meal, falling through so much atmosphere, becomes dry.
A current or blast of air coming up through the chamber, creates an upward draught, which tends to suspend the particles of meal in the atmosphere for a greater length of time than when no draught is created, and for this purpose are orifices c c.
If the meal is particularly damp, warm air may be introduced, at c c, in the chamber E, with entirely satisfactory results, either by natural currents, or by blastsof warm air.
The tailings, or coarser parts of the meal, that part which does not pass through the sieve, is carried to the box H, and thence by pipe P, and fed directly upon the shoe S, under the opening of the hopper. Mingling with the'grain coming from the hopper, it is passed through the mill again, and, being reground, is carried up by elevatorto sieve F.
Some particles of the tailings may, in this way, be carried through the mill many times, and the tailings are so deposited upon the shoe S, that they do not clog the supply of new grain from the hopper, unless the amount of tailings is large, and then they check the corn, so that the mill is properly fed with grain and tailings in right quantities.
There is more or less heat generated by the movement of the stones, and this heat exerts some influence upon the meal, drying it in a certain degree, but
not enough to exclude the moisture; and, in. the old way'of grinding, or rather, putting up meal, the dampness and all is bagged; but, with my invention, the tailings, returning as they do to the mill, I avail myself of the heat of the mill, by using it over again.
I find, by actual use of this invention in connection I with our mills, that it operates to a perfect success,
and we are enabled to grind grain two or three months earlier than by the ordinary methods. This invention is best applicable to corn than to other grains.
The advantages of drying meal instead of grain in the kernel, are apparent, from the fact that the grain, being broken, is more susceptible to the influence of air than in the whole.
What I claim as new, and desire to secure by Let-- ters Patent, is-
1. The pipe P, leading to the shoe S, and discharging directly under the openihg of the hopper B, all arranged as described, for the purpose of regulatinga uniform supply of grain and tailings to the mill, substant-ially as set forth.
2. The drying-chamber E, in combinationzwith mill A, elevator D, sieve E, box H, pipe I, and draught c c, all arrangedand operated substantially as herein described. I
In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
HENRY CUTLER.
