These hearing plates support a" proximity to the hotnutor screw 13 ndjustahle in the lower hub portion 1d` of gav {rostro-conical shaped crushing head 15 having :in upper huh prtion 16 extending'into a housing 17 carried by a hopper spider 18; The spider housing 17 contains `an indureyte liner `lll'ageinst which hears the lower \m'1hla`r edge of a oonical'tbushine 20 mou end of the hug` portion 6 of the crushm head. The housingkopenin 21 for the hu portion 16 is large enough or" the lWobhling` ted on the upper nmvemexit of the hub portion" 16 in thefhous- `r `V`ment of the hub portion 16 within the spider Sfhousing' 17.

The hub portion 16 is coaxially of the hub portion 14. Extendingl through the hub portion 16, the head 15 and into the nutor screw 13 is a rod 23 having tanns or end Shanks so that a wrench or suitable instru- `ment on the upper end of the rod 23 will permit ofitfbeingrotated to impart rotation to the nut or screw 13 and thus raise or lower the crushing head 15 relative to the spider housings 10 and 17. l

Mounted on thelower hub portion 14 of the crushing head is a bushing 24 and mounted on this bushing is an inner rustroconical shaped race member 25 which has its outer wall undulating, as best shown in Fig.` 3, to provide a plurality of protuberances or cam surfaces 26. Attached to the lower end of the inner race member 25'is a bearing ring 27 on a wear plate 28 supported by the housing 10.- This bearing ring is the equivalent of a' plurality of brackets for supporting the inner race member 25 so that the lower hub portion l14\of the crushing head maybe adjusted in the inner racc member.

The bearing ring 27 supports the inner race member so that it may be laterally shifted when an oscillatory motion `is impartedto the crushing,head;..&..5L,-

In' the lower part of the'housin 10 is a rotatable worm wheel 344 provide with a pin 35 extending into a lateral fork 36 fixed on the bearing ring'27, thus establishing a' driving relation between the worm wheel 34 and the inner race member 25. The housing '10 has suitable bearing portions for a worm 37 meshin with a worm wheel 34 and adapted to be driven from a suitable source of power.

The crushing head 15 has a' depending an- Anularskirt 38 surrounding the upper end of the housing 10 and between the skirt and said housing may be a conventional form of dust guard 39.

claims.

Mounted on the crushinfr head 15 are interchangeablc and renewable concaves 40 rctained thereon by suitable clips 41 or other fastening means. These concaves confront the liner 7 of the crushing chamber 8 and it isvbetwcen the walls of the crushing chamber thatmaterial from the hopper 5 is sub jected to av crushing action brought about by the oscillatory movement of the crushing head relative to the outer wall of the crush- 7 ing chamber.

In operation the inner race member 25 causes a-gyratory movement to be imparted to the lower part of the crushing head and such movement is permissible because the bearing ring 27 and bearing plates 12 are shiftable relative to the housing 10, while the upper hub portion 16 of the crushing head is supported for a wobbling movement within the bearing provided by the spider` housing 17. The gyratory movement imparted to thecrushing head 15 causes it to constantly shift in an eccentricrelation to the outer wall of the crushing chamber with resultant radial and tangential strains against material between the. walls of the crushing chamber. This will insure greater and more rapid disintegration of the material which is conveniently discharged through the bottom shell of the machine. 95

In lieu of the conical anti-frictional rollers 31 between the race members 25 and 29 of the-Crusher, we may use straight rollers 42 as shown in Fig. 4. We may also substitute a horizontal beveled gear wheel 43 and a driven beveled gear wheel 44 for the worm and worm wheel 'previously described. A bearing ring 45 may form partof the inner race member 46 and have a pin and slot con- We may also suitably support a crushing head 47 from overhead and provide a snpporting core 48 of said head with a ball and socket connection 49 in the inner race member 46.' rlhe ball and socket connection 49 will constitute a universal connection between the crushing headand its operating mechanism, so that the driven inner race member 46 may impart a gyratory motion to the crushing head. The universal joint also permits of the crushing head 47 being readily adjusted when occasion requires, and we do not care to confine our invention to -any particular supporting or suspension means Jfor the head 47, as our invention is p'articularlv directed to the operating or actuating mechanism by which the gyr'atory motion is imparted to the crushing head. Furthermore, it is to be understood that the construction and arrangement of parts are 511s-, V ceptlble to such variations and modifications as fall within. the scope of th appended crushing chamber,
