a casing, a shaft mounted in said casing. disks fixed to said shaft and provided with' radial slots, inclined rods passing througl.- said slots, revolving hammers pivotaly mounted on said inclined rods between the disks, 'adjusting means on the shaft and conl radial slots, inclined rods passing through said slots, sliding disks mounted on the shaft for supporting said rods, means located on the shaft and connected to one of the sliding disks for moving both of said'disks upon the shaft, revolving hammers pivotally mounted on the rods between the xed disks, and means for `loekiifi'g said sliding disks and their carried inclined-rods in longitudinally adjusted positions.

4. In a pulverizer, a casin a shaft mounted for rotation therein, dis s fixed on said shaft, disks arranged toslide on said shaft, inclined rods carried by thel slidin disks, which inclined rods pass through t e fixed disks, revolving hammers pivotally mounted on said rods, and spacing rings arranged between the hammers.

l5. In a pulverizer, a casing, a shaft mounted foi` rotation therein, an adjustable frame mounted on.the`shaft, which' frame comprisesdisks andinclined rods, a series of revolving hammers pivotally mounted and spaced apartlupon the inclined rods, and means carried by the shaft whereby the hammersare held to move radially with respect to the shaft when the frame is adjusted upon.

6. In a pulverizemacasing, a shaft mounted for rotation therein, a pair of disks fixed on the shaft and provided with radial slots, inclined rods passing through said slots, sliding disks mounted on theshaft and engaging the ends of the inclined' rods, revolv ing hammers votally mounted on the rods between the xed disks, spacing rings carried by the rods between the hammers, means whereby the sliding disks areshifted upon the shaft, and means whereby the rod-.shifting means is locked after movement.
