According to the rollers taper as described the shell is capable of a slight rocking movement t0 compensate for any irregularities in the surface or covering' of the roll.

If it be desired to remove a roll from the arbor it may be done in the manner shown in Fig. 3; the nut, F, being first withdrawn and then the shell with the rollers supported on the collar, r, may be lifted olf without my present invention I simplify the construction of top rolls of this kind.
