I JOHN WIGHAM of South Hylton Engine Works, Sunderland, Engineer do
hereby declare the nature of my invention to be as follows:-
The object of this invention is to construct or arrange a whipping drum,
available for lifting or whipping coal, grain and other material or articles from
vessels, also for hauling or lifting material from cellars or other places, by making
the whipping drum of skeleton form with broad flanges for the rope or chain and
with a ring flanged projection in which a brake may be caused to act.
The inside
of the drum is formed conical for a friction cone to bite against for power and
can be in connection with a clutch by which the motion can be regulated or
determined.
The clutch mechanism and the brake mechanism can be so arranged that they
shall act simultaneously or be under such control that each may act separately the
flanges of the whipping drum being preferably bolted or screwed in place.
This whipping drum is applicable to ships winches, cranes or any other machinery
to be easily shipped and unshipped and can be used with wire or other ropes.

I, JOHN WIGHAM of South Hylton Engine Works, Sunderland, Engineer, do
hereby declare the nature of this invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
The object of this invention, is to construct or arrange a whipping drum,
available for lifting or whipping coal, grain, and other material or articles from
vessels, also for hauling or lifting material from cellars, or other places, by making
the whipping drum of skeleton form with broad flanges for the rope or chain, and
with a ring flanged projection, on which a brake may be caused to act. The inside
of the drum is formed conical for a friction cone to bite against for power, and can
be in connection with a clutch by which the motion can be determined. It has
also a collar on its boss to bear against a shoulder on the shaft to prevent it moving
with the clutch.
The clutch mechanism and the brake mechanism may act simultaneously if
desired. The winch, which is of ordinary construction requires simply to be set in
motion and each man at the whip is entirely independent of the other in starting
or stopping the whip.
.
This whipping drum is applicable to ships winches, cranes, or any other
machinery to be easily shipped and unshipped and can be used with wire or other
ropes and worked from both sides of the winch.
This invention will be understood by reference to the annexed drawings in which
Figure 1 is a section of the improved arrangement of whipping drum. A is the
drum or whip with conical portion B and flanges C C bolted or screwed in place.
It is secured on the shaft D by collars E, F, but revolves loosely upon said shaft,
and is driven by a friction cone G moving with the shaft and provided with
clutch H or its equivalent. The brake I takes against the ring J of the drum.
The small collar E on the outside end of the drum or whip A prevents the whip
from coming back with the friction clutch on throwing out of gear.
The advantages of this invention are, the facility with which wire or steel rope
can be used for discharging or taking in cargo or other purposes without (like the
ordinary method) tearing the hands of the men since they do not touch it ; and
the great saving in manilla rope as it wears much longer.
The man at the whip having only to operate an ordinary clutch lever and brake,
can also look down the hatch and thus be able to know what he is doing without
requiring a man at the hatchway to call out " heave" or "lower" which is often
the cause of accidents.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
The improved arrangement of whipping drum (for steam winches &c) wherein
the drum A is loose, not keyed to the shaft, but operated by a friction clutch G H
or its equivalent and having a collar E at its outside end to prevent it moving
with said friction clutch as hereinbefore described and shown on the annexed
drawings.
