Specification of Letters Patent.

Application area February is, 1909. se ial 80. 478,214.
*Be it known that I, MILTON J. WILLIAMs, a citizen of the United States, residing at Chicago, Illinois, have invented a certain new and useful Improvement in Pulver izers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which Figure l is a vertical sectional view through a pulverizer constructed according to my improvement said view being taken on the line l1, Fig. 2, looking in the direction of the arrows; Fig. 2 is 'ahorizontal, fragmentary sectional view through the same said viewv being taken on the line 2 -2, Fig. 1, looking in the direction of the arrows.
This invention relates to a new and useful improvement in pulverizers of that type commercially known as .the Williams mills, characterized by the pivoted revolving hammers which act' upon the material as it enters the machine'at the hopper or feed end thereof, crushing said material as it rests u on the bottom of the hopper, or breaker p ate, as it' is sometimes called, the material being further disintegrated or crushed by the hammers acting thereon as the material is carried over the cage or rlnding surface. The crushed material allsthrough the openings in the cage or grindingsurface into a suitable receptaclelocated beneath the machine. The hammers or beaters which revolve about the shaft, while made of a material whose resistance to wear is its essential quality, will, in time, wear away'at their striking ends, and the farther these striking ends are removed from the breaker plate and grinding surface, the less becomes the capacity of the machine. 1
It is thepurpose of my present invention to provide means whereby these revolving hammers or beaters maybe adjusted outwardly totake up this wear (or inwardly, if occasion requires, as when a new cage is introduced to replace a worn one), said means consisting of a rotary sleeve having projections which coiiperate with the hammer supports to adjust said hammers outwardly, whereby all of said-hammers are adjusted simultaneously and uniformly. I In the drawings, 1 indicates the casing, 2 the breaker plate, 3 the grinding surface or cage, and 4.the cover of the machine, which may or may not be huiig, as desired.
5 is a shaft mounted in the casings on which are fixed two disks 6.
7 are screw bolts carried by the disks and on which are pivotally mounted levers 8,
said levers being spaced apart in any suitable manner.
9 are hammers pivotally mounted in the outer ends of the levers.
10' is a sleeve rotatively mounted onshaft 5 between disks 6, said sleeve having longitudinal ribs or projectionswhich cooperate with the inner ends ofthe levers 8. The inner ends of levers 8 are referabl curved, as shown, so that a consi erable a justment of the hammers may be effected with a slight rotary movement of the sleeve. One of the projections '11 extends through openings in the disks 6 and cooperates with adjusting screws 12. By the use of these screws, sleeve 10 may be circumferentially adjusted on shaft 5 to adjust .the levers forming the hammer supports and take up the wear on the ends of the hammers.
, I am aware that minor changes in the construction, arrangement and combination of. the several parts of my device can be made and substituted for those herein shown and described, without in the least departing from the nature and principle of my invention. a
In using the expression disks in the foregoing specification and in the following claims, I wish to beunderstood as not confining myself to circular disks, .as the parts which perform the functions of the supporting disks described and claimed could be in the shape of spider-arms, or other forms, metal being cut away at various places, where it wasnot needed, tolighten the machine. V
Having thus describedmy invention, what 'I claim is:
1. In a pulverizer, the combination with a casing, a shaft mounted therein, disks on said shaft, hammer supports carried by said disks, a rotary-element mounted on the shaft between the disks for cooperating with said hammer supports to adjust the hammers outwardly, and means for locking said rotary element in adjusted positions. v
2.- In a pulverizer, the combination with a casing, a shaft mounted therein, disks fixed on said shaft, hammer su ports pivotally supported by said disks, ammers in the outer ends of said supports, a rotary sleeve having projections for cooperating with the inner ends of said hammer supports, and
-means for locking said rotary sleeve inadengaging parts of the rotary sleeve for shift ing the same.
seems at. In a puiverizer, a casing, a shaft mounted for rotation therein/disks fixed on said shaft, hammer supports carried by said disks, hammers pivotally carried by the hammer supports, and a rotary element mounted on the shaft between the disks for (:06 seating with the hammer supports "to simu'taneously and uniformly adjust the hammers inwardly and outwardly.
In testimony whereof I hereunto afliix. my signature in the resence of two witnesses, this 8th day of F e ruary, 1909.
