Description
AHENRY ALBRGHT, OF CRANESVILLE, VVES'I VIRGINIA.
Letters Patent No. 90,978, dated June 8, 1869.
IMPROVEMENT IN GRINDINGMILLS.
The Schedule referred to in these Letters Patent and making part of the same.
To whom it may conce/m:
Be it known that I, HENRY ALBRJGHT, of Cranesvil1ein the county of Preston, in the State of West Virginia, have invented anew and improved Mill for Grinding Grain; and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanying drawings, and to the letters of reference. marked thereon.
' The invention consistsinthe peculiar construction of the devices by which the grain is fed between the -mi11stones; also, in a means for feeding middling 'to be reground into the shoe or shaker, which delivers it into the feeding-cup. Y To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and' operation.
In the drawings- Figure 1 represents a perspective of the mill;
Figure 2, an upright section of same, showing the different parts; Figure 3, the damsel; and
Figure 4, the bottom plan of feeding-cup and damsel.
A is the upper stone or runner, and having the usual-shapedeye, and driven by the usual devices.
B is the curb or casing around the stone.
G is the frame, resting upon the curb, and support` .ing the shoe E.
F is a transverse brace supporting the metal chute f. a. is the damsel.
b is the feeding-cup.
b' b are feeding-tubes from the bottom of the cup,
Awhich convey the grain to the bottom of the runningreduce the size of the stones, and therefore the cost;
but to do this, the revolutions of the stone have to be increased in proportion as the stone is smaller in diameter, for the theory of grinding is conned to a general law, which is, the quantity ground is proportioned to the number of cutting-edges, and amount of grinding-surface brought in contact with the grain in a given time.7
Therefore, in millstones of small diameter, the revolution is so rapid that the velocity of motion in the inside of the eye overcomes the gravity of' the grain, and the grain coheres to the eye, and soon ills the eye with grain,none going between the stones; .and to obviate this diiculty, this invention is mainly to apply.
I use the common hopper and shoe, but the damsel is differently constructed from those in common use, as it stands in the feeding-cup, and has a peculiar shape at its base, fitting into the feeding-cup closely, excepting where it is cut away to allow the grain to be surely fed into the tubes b', and thence between the ston'es, to' be ground.
The general form of the damsel is conical, but has the base which fits into the feeding-cup extend upward to a point or ridge on opposite sides of its axis, and cnt out, as seen at a a', so that no grain ca'n lodge therein, but surely go into the feeding-tubes b b', and thence between the stones,'\to be ground.
By this construction and arrangement of devices,
the grain is always Sure to be fed, without interruption, between the stones, be ther-evolution of the stone greater or less. v
In many mills where the finer quality of iiour is made, itis necessary to regrind the middling or coarse flour, and such middlings or coarse flour has to be conveyed back to the mill from the bolt, to be reground; and when, as is usually the case, such coarse flour is placed in the ordinary tapering hopper, it nill not readily feed into the shoe, to be delivered into the .feeding-cup, thence through the pipes b' b', between the stones, but will pack at the lower and smaller part of said hopper.
To obviate the diculty, I construct a tube, d, upon one side of the hopper, having the opening d gradually increase in size until it gets to the bottom of the hopper, which will always insure the coarse flour from impact, and allow it to constantly and freely pass into the shoe, where it'is fed into the feeding-cup, and through pipes b b', between the stones.
In the formation of the feeding-cup and damsel, it is obvious that more than twotubes b' b can be used, for four may be used, if necessary, and not depart from my invention.
I am aware that tubes for feeding the grain through the eyes of millstones have been long in use; and I do not claim such tubes of themselves; but
What I do claim, and desire to secure by Letters Patent, i`s
1. The combination of the damsel a., feeding-cup b, and tubes b' l, all constructed in the manner, and to operate substantially as described.
2. The conducting-tube d, when constructed upon, and arranged to operate with the hopper D, in the manner and for the purpose substantially as set forth.
HENRY ALBRIGHT.
