The disk I is constructed o'nfthe outer side with a central hub, is, andis held in place4 by an outer plate,'D1, extending at its edgesl ast the periphery of the disk, in order to hear firmly 'against the outer face of the bod plate D, to which it is firmly secured byliorizontal screws, d, the two platesA D forming in effect-.ay rigidmframe within 4which the plate I is seated.

In order to aid the'operator in adjusting the'knife-to produce slugsof different thicknesses andv to indicate the adjustment, the
