NEWTON A. PATTERSON AND WILLIAM C. HALE, OF JOHNSON CITY, AS- SIGNORS OF ONE-HALF F THEIR RIGHT TO GEORGE F. GAMMON, JR., OF AUSTIN SPRINGS, AND JOHN WHITE, OF JOHNSON CITY, TENNESSEE.
GRINDING-MILL.
SPECIFICATION forming part of Letters Patent No. 231,354, dated August 1'7, 1880.
Application filed November 20, 1879.
To all 'whom it may concern Be it known that we, NEWTON A. PATTER- soN and WILLIAM G. HALE, both of Johnson City, in the county of Washington and State 5 of Tennessee, have invented new and useful Improvements in Grinding-Mills, of which the following is a specification.
The invention relates to a brush and evaporation and cooling tube attachment for grind- Io ing-mills.
Our improvement consists in providing` the ruiming burr with peripheral brushes which sweep t-he chop to the exits ofthe channel, in combination with chutes having a covering of fibrousmaterial to permit the heated air to escape while the flour is passing from the stones, as hereinafter set forth.
In order that the invention maybe more fully understood, we will proceed to describe it with 2o reference to the accompanying drawings, in
which- Figure 1 is a top view of the improved grinding-mill, showing the varying angle of the brushes. Fig. 2 is a Vertical section on the line 3 3, Fig. 1.
A lnay represent the supportingplate, on which rests the bed-stone l, and having exits al a a. a connecting with transmitting tubes or channels a a. a. a for the pul'verized mate- Ilal.
2 is the upper millstone or runner, secured to the vertical shaft S, journaled in the lower stone, 1, and the top T of the casing, which ,rests on the curb U. A hopper, V, is located 3 5 over the eye of the upper millstone.
The upper burr is furnished with brushes W, of any suitable material, and rigidly secured to the band X. These brushes are applied in such a way as to sweep the channel at dierent angles, so as not to create a too strong 4o current of air.
The exits a are provided with chutes a. a' a a leading to a suitable receptacle beneath. These chutes are constructed of suitable sheet metal or wood in their bottoms and sides, but have their upper sections covered with a fine Wire-gauze or suitable textile fabric, a", so as to allow an easy escape of the heat and combustible material separated from the our by the currents of atmospheric air generated by 5o the brushes.
It is found that with a level covering to the spouts or chutes the air-currents, though broken and small, created by the brushes cause the flour to fag out down' where the millcrs 55 hand is inserted to test the grinding, and, although almostimperceptible, yet in a few days the surroundings are whitened and coated with flour. We have arranged the covering in an arched form, which obviates this difficulty 6o fully and greatly enlarges the surface of the covering, so as to well and fully allow the air and combustible material to escape, avoiding all air displacement at the lower exit.
Having thus described our invention, the following is what we claim as new therein and desire to secure by Letters Patent:
The running burr provided with peripheral brushes which sweep the chop to the exits of the channel, in combination with' the chutes 7o having a covering of fibrous material to permit the heated air to escape while the flour is passing from the stones, as set forth.
