By partially extracting the cork it makes it easier to pull it out the
rest of the way. Partial pullers all have some form of bell at the
base of the shank.

Two American companies Edwin Walker & The C. T. Williamson
company produced significant numbers of corkscrews with bell
caps & indeed, Williamsons produced this type of corkscrew right
up to the mid 1900's.

The example to the right has a small bell cap & is probably a
German copy of William Bennit's American 1883 patent.
I've enjoyed compiling this corkscrew guide, I hope it can be of
assistance to you. If you'd like to get in touch it would be great to hear
from you.
