comminuted condition-and the object of my invention, is to improve the machine shown and described in Letters Patent of the United States No 777,779 issued Dec.
My invention consists generally in an implrlgved arrangement of revolving cutters or was andin an improved way of mounting and adjusting the stationary knives.

Fig. 3, is a plan view. Fig. 4,; is a side, View. Fig. 5, is a sectional view illustrating the manner of mountin and adjusting the stationary knives. Figs. 6
and 7, are detailed sectional views illustrating the manner of mountin the knives in the revolving drum or cutter head.
In the drawing, 2 represents the base of the machine, and 3 a shaft having a pulley 4 secured thereon. The cutter. head is secured on said shaft and consists of two truncated cone sections 5 placed end to end on the shaft and having hubs 6. These sections when assembled as indicated inFig. 2, form the revolving cutter head of the machine with an annular V shaped recess in its periphery. Boxes 7 are mounted on the base and are adjustable by means of threaded bolts 8 which are tapped into the base and connected with said boxes by. means of lugs!) and nuts 10. By the adjustment .of the boxes on these bolts, all lateral movement of the cutter head can be taken out, ihelo ends of the boxes being set close to the In the converging faces of the-cutter head,
sections, knives are mounted, arranged preferably in pairs in staggered relation to one a; another sothat the cutting edge of one pair or gm of kniveswill be is set or out of line with the cutting edge of the preced= inggt'eup, as shown in Figs. 8 and 5. These knives, I will designate by reference nu ei' me'ral 11, each knife having a. beveled cut.
volving knives.
On one side of the machine, is a vertical anvil plate 18 that is adapted to depend within the V- shaped recessin the cutter head and is supported at-each end on the machine casing. (See Fig. 3.)' The lower edge of this anvil plate has a series of notches 19 formed therein and below the said plate, is an anvil 20 having flaring walls'and provided with notches 21 forming seats .for 9.80 series of normally. stationary knives 22 whose upper edges enter the notches 19 in the anvil plate and are held securely by said late.

The material fed to these knives will be crushed and reduced, its degree of fineness depending upon the adjustment of the knives.
The stationary knives bein interchange able and adjustable indepen ently of one another, I am able to remove one or several if desired, for the purpose of grinding them orfor repairs without the necessity of disturbing any of the other knives. The adjustment and operation of the machine is thus greatly facilitated.
