What I claim and desire to secure by Letters Patent is:
1. A vibratory crusher including, a supporting frame,
a ?rst crushing anvil carried by said frame, a second

anvils, a motor having a shaft resiliently mounted on

of the invention may be regulated through the selected
vertical positioning of the sleeves 47 upon the supports
46, and in the alternative structure of the form of the 35
invention shown in FIG. 1, by loosening and vertical

eccentric vibratory movement of the resiliently mounted 40
