MILTON J. WILLIAMS, OF CHICAGO, ILLINOIS.

- PULVERIZER.

Specification of Letters Patent.

I Patented Nov. 9, 1909.

Application filed February 16, 1909. Serial No. 478,215.

To all whom it may concern:

Be it known that I, MILTON J. WILLIAMS Chicago, Illinois, have invented a certain new and useful Improvement in Pulverizers, of which the following is a full, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical sectional view through a pulverizer constructed according to my improvement. Fig. 2 is a horizontal fragmentary sectional view. through the same. Fig. 3 is an elevation of one of a pair of disks which are fixed on the main shaft .of the machine, and through which the adjustable rods pass.

This invention relates to a new and useful improvement in pulverizers of that t pe commerciallyknown as the WVilliams milis 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 upon the bottom of the hopper, or breaker plate, 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 grinding surface. The crushed material falls through the openings in the cage or grinding surface into a suitable receptacle located beneath the machine. The hammers or heaters 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 It is the purpose of my present invention to provide means whereby these revolving hammers or beaters may be adjusted outwardly to take up this wear (or inwardly, if occasion requires, as when a new cage is means consisting of hammer supports pivotally mounted upon disks arranged upon a shaft, the inner ends of said hammer supports being slotted-to receive rods which are mounted in rotatable disks whereby the hammers may be simultaneously and uniformly adjusted, outwardly and inwardly, with respect to the shaft.

In the drawings, 1 indicates the casing, 2 the breaker plate, 3 the grinding surface or cage, and f the cover of the machine, which may or may not be hung, as desired.

5 indicates a shaft and 6 disks fixed thereon.

7 are through-bolts, on which are mounted hammer supports 8, said hammer supports having hammers 9 mounted in their outer ends. The inner ends of the hammer supports are slotted, as shown in Fig. 1, to receive rods 10 passing through circumferentially disposed slots in the disks 6 and mounted upon adjustable disks 11 arranged on shaft 5. These disks 11 have projections 12 on each side in which are seated circular heads of adjusting bolts 13. These adjusting bolts pass through threaded ears 14 on the disks 6 and are provided with heads by which they may be rotated to adjust the disks 11.

In operation, when the hammers are new, the hammer supports are tangentially disposed as shown in Fig. 1. As they wear, the disks 11 are circumferentially adjusted so as to bring the hammer supports nearer to a radial position, these adjustments being continued, from time to time, until the hammer supports are radial, when no further outward adjustment can be effected.

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.

In using the expression disks in the foregoing specification and in the following claims, I wish to be understood 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 was not needed, to lighten the machine.

Having thus described my invention, what I claim is:

1. In a pulverizer, the combination with a casing, a shaft mounted on sald casing. disks mounted on said shaft, hammer supports pivotally mounted between said disks. the inner ends of said hammer supports being slotted, hammers carried by the outer ends of said hammer supports, rods cooperating with said slotted inner ends and means for circumferentially adjusting said rods.

' a casing, a shaft mounted on said casing,

disks mounted on said shaft, through-bolts supported by said disks, hammer supports pivotally mounted on said through-bolts, hammers carried by the outer ends of said supports, the inner ends of said supports being slotted, rods passing through circumferentially disposed slots in said disks and engaging the slotted ends of said supports, rotatable disks in which said rods are mounted, and means for circumferentially adjustsaid rotatable disks and locking them in ad usted positions.-

In testimony whereof I hereunto aflix my 15 signature" in the presence of two witnesses, this 8th day of February, 1909.
