Description
JOSEPH H. HEISHMAN, 0F PORT I-IURON, MICHIGAN.
GRINDING-PLATE FOR MILLS.
Specification of Letters Patent.
Patented Apr. 18, 1916.
Application filed. October 27, 1914. Serial N 0. 868,791.
To all whom it may concern:
Be it known that I, JOSEPH H. H IsHMAN, a citizen of the United States, residing at Port Huron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Grinding- Plates for Mills, of which the following is a specification.
My invention relates to metal grinding plates such as are particularly used for feed and corn mills; it consists in an improved dress therefor comprising a series of radial ribs and series of differently inclined cross-wise ribs connecting the same, as hereinafter fully described in connection with the accompanying drawings, and the novel features of which are specifically pointed out in the claims.
The main objects of the invention are to provide for securing the most effective action upon the material operated on, by causing these ribs, as formed upon the bed and runner respectively, to advantageously coact at varying angles; and further to accomplish this by the use of like plates for both bed and runner, and by rotation in either direction.
Figure 1 is a partial face view of a grinding plate embodying my invention in preferred form; and Fig. 2 is a cross-section on the line 2-2 of Fig. 1.
My improved plate may be obviously formed either in a single piece, or in sections, as preferred; and the dress may be duplicated upon the opposite faces as is indicated, or not, as desired. It is adapted, as shown, to be used in connection with each of a pair of suitable opposing disks, mounted to serve respectively as the bed and runner of a grinding mill; and also to similarlycooperate with the opposing plate whether the runner be rotated in one direction or the other; the advantage of which capacities in the way of simplicity and economy, will be readily understood;
Between the central opening or eye 2 of the circular plate, and the circumferential skirt 3 thereof, extend a series of radial ribs 4, 4, 4, rising from the body 8 of the plate and suitably spaced apart thereon; and between these radial ribs extend similar connecting cross-wise ribs 5, 5, 5, and 6, 6. 6. The upper faces of all of these ribs lie in the same plane, excepting as certain of them are reduced in height adjacent the eye 2, as indicated at 7 7, 7 so as to fade into the body other of the ribs 4. These inner ends, as shown, are formed with dlverging branches 4f, 4*, which are deflected in opposite directions from the radial line o-f'a rib 4, and are thereby adapted to serve respectively as leader walls for right or left rotation of the runner. Each of the connecting ribs or cross-wise teeth is arranged at an incline so as to intersect two adjacent radial ribs 4, 4 at different angles, one of which, as at 10, is an acute angle, and the other, as at 11, an obtuse angle. And they are arranged in different series, 5,.5, 5, and 6, 6, 6,alternatlngly placed as shown; with the ribs 5 of one series and 6 of a different series converging in pairs to a given radial rib 4, from adjacent ribs 4, 4 on opposite sides of the latter; the angle of convergence of the connecting ribs 5 and 6 pointing inward on one radial rib, and outward on the adjacent radial ribs as illustrated.
When a pair of my improved plates is opposingly arranged in a mill, as bed and runner respectively, the action of the ribs or teeth 4, 5, and 6 upon the interposed material fed thereto from the eye 2 as usual, is peculiarly effective because of the difilering coactions of the differently inclined connecting ribs 5 and 6 at their passings during rotation of the runner. These may be under stood by reference to the suggestive clottedline showings in Fig. 1 of different relative positions of the opposing plate; which, for convenience, will be termed the runner. The dotted-line showing at a indicates a relative position of the runner plates at which the cross-wise ribs of the latter (dotted lines) are at about right angles to those of the bed plate; and the resulting action upon the interposed material may be described as of a.-
shearing character. The dotted-line show ing at 0 indicates another relative position of the runner plate at which the cross-wise ribs of the latter (dotted lines) are about parallel to coacting ribs of the bed plate; the resulting action in such case being of acrushingor cutting character. The dottedline showing at Z) is similar to that at a excepting that a different series of connecting ribs on each opposing plate is involved; with the difference in result that the shearing action is effected with an outward push upon the material (or toward the skirt), instead of an inward push at a. This description applies to a direction of rotation of the runner indicated by the arrows, but a reversal of rotation will simply reverse the pushing action in each case and secure the same result upon the materiah This change in direction of the push upon the material obviously occurs also in the cutting or crushing action of the ribs as indicated in one relation only at 0; so that it will be readily understood that the material under treatment is being constantly and repeatedly subjected to different reducing actions in its passage from the eye to the skirt, so as to insure the securing of satisfactory results and a maximum output. The specific construction shown and described may be readily modified without departing from the invention as for instance by Varying the particular angles or the straight-line form of the connecting ribs.
What I claim is:
1. In a grinding mill, a grinding plate having a series of radial ribs, and alternating series of inwardly and outwardly inclined cross-wise ribs connecting said radial ribs; the cross-wise ribs of adjacent series converging in pairs to an intersecting radial rib.
2. In a grinding mill a grinding plate having a series of radial ribs, and alternating series of inwardly and outwardly inclined cross-wise ribs connecting said radial ribs; the cross-wise ribs of adjacent series converging in pairs to an intersecting radial rib and certain only of the latter having the side walls of their inner portion deflected from the radial in opposite direc tions to form right and left leaders.
In testimony whereof I aiiix my signature in presence of two witnesses.
JOSEPH H. HEISHMAN.
