FEEDING DEVICE FOR GRINDING-=MILLS, 80c.
EJPECIFICATION forming part of Letters Patent No. 340,789, dated April 27, 1886,
Application filed December 17, 1885. Serial No. 185,963.
To (tZZ whom it may concern.-
Be it known that I, M. OGDEN KASSON, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Feeding Devices for Grinding-llIills, &c of which the following is a specification.
This invention relates to an improvement in that class of feeders which are employed in grinding-mills and other machines for feeding the material to the grinding-surfaces or other parts which operate upon the material.
The invention has special reference to that class of grinding-mills in which wet or damp l 5 material is treated, which is liable to choke the fced'spout, thereby interrupting the feed and causing the machine to runempty, which results in various wcll-known difficulties. Machines of this kind are, for instance, the grinding-n1ills which are employed for reducing sawdust in the manufacture of papenpulp. In these machines the sawdust, which is usu ally damp or wet, frequently clogs in the feedspout, thereby rendering the operation of the machine very irregular, and requiring constant attention in order to avoid serious injury to the grinding-sorfaces.
The object of this invention is to provide a simple feeding device which w ill automatically o maintain a uniform supply of material to the grinding-surfaces or other parts which operate upon the material; and my invention consists to that end of the improvements which will be hereinafter fully set forth, and pointed 5 out in the claims.
In the accompanying drawings, Figure 1 is a vertical sectional elevation of a pulp-mill provided with my improvements. Fig: 2 is a horizontal section in line a: m, Fig. 1..
Like letters of reference refer to like parts in the several figures.
A represents the grinding-cone; B, the conical shell surrounding the cone A; a, the vertical spindle to which the grinding-cone A is 4 5 secured; b, the feed-hooper, and c the throat of the feed-hopper or feed-tube leading to the upper end of the grinding-shell B. All of these parts may be constructed in. any wellknown or suitable manner.
(No model.)
D represents the conical feeder, which issecured to the spindle a in the throat c of the feed-hopper above the grinding-cone A. The v the axis of the spindle at an oblique angle, and
has the form of an ellipse, which is arranged at all points at a uniform distance from the inner cylindrical surface of the feed-tube 0, so that the annular space 6 between thelower edge, (I, of the feeder and the inner surface of the fcedtube a has the same width at all points. The lower edge, (I, of the feeder is therefore highest atf on one side of the spindle, and lowest on the dianietrically-opposite side at g, and the angle of the surface of the feeder is least inclined in the side line drawn through the highest point, f, and steepest in the side line drawn through the lowest point, g, while the angles of the side lines increase gradually at all intermediate points from the highest point, f, to the lowest point, g. The surface of the feeder having this unequal inclination and unequal height at different points circu n1- ferentiall y, the rotation of the feeder about the axis of the spindle causes a rapid rising and falling motion in the material resting on the feeder, whereby the material is shaken and loosened, thus preventing clogging of the material in the feed-tube. As the space 6 is of uniform width all around the base of the feeder, the material is uniformly distributed circumferentially and fed in uniform quantities to all parts of the grimling-surfaces. Usually a stream of water is directed between the'grinding-surfaces from a suitable supply-pipe, 71. This stream is delivered upon the feeder, and thereby distributed with the material to be ground, thus insuring a proper supply of wa ter to all parts of the grinding-surfaces.
2' represents an annular flange or collar, which is secured to the under side of the feeder D, and which rests upon the upper end of the grindingcone A, thereby supporting the feeder upon the cone. The feeder is secured at its upper end to the spindle a by a collar, j, and set-screwk, or other suitable means, prefcrably in such manner as to be vertically adjustable on the spindle.
The feeder is preferably constructed of galvanized iron; 'but it may be formed of castiron or other material, if desired.
By this improved feed all the furrows in the grinding-surfaces are uniformly supplied with the proper quantity of material, thereby enabling the machine to work to its full capacity while employing all parts of the grinding-surfaces alike, whereby the wear of the grinding-surfaces is equalized and the life of the machine correspondingly lengthened.
I claim as my invention 1. The combination, with the feedtube, of a revolving feed-cone having its lower edge arranged obliquely to the axis of rotation, substantially as set forth.
2. The combination, with the feed-tube, of a revolving feed-cone having its surface made of varying inclination at different points eircumferentially, whereby a rising and falling motion is imparted to the material resting on the feed-cone, substantially as set forth.
3. The combination, with the feed-tube, of
width between the lower edge, d, of the feed- 0 5 cone and the surrounding feed-tube, substantially as set forth.
5. The combination, with the grinding-cone A, spindle a, and surrounding shell B, of the revolving feed-cone D, secured to the spindle 0 a above the grindingcone, and provided with an annular flange, i, which rests upon the grinding-cone, substantially as set forth.
lVitness my hand this 4th day of December, 1885.
