page_text: I, DAVID DEHANE NAPIER, of 100 Hyde Park Street, Glasgow, in the County,
of Lanark, North Britain, Engineer, do hereby declare the nature of this invention
to be as follows, that is to say :-
My said Invention has for its object the construction of a simple and compact
steam winch to serve as a cargo whip, and it comprises arrangements for con-
trolling the action of the steam in connection with the clutch through which the
winding barrel is driven.
My improved cargo whip or winch is made with a bedplate having on it two
steam cylinders, driving a crank shaft which has on it a worm driving a worm-
wheel on the shaft of the winding barrel. The winding barrel is loose on its shaft
and is driven from it by means of a clutch which can be put into or out of gear by
means of a hand lever. Steam is supplied to the two cylinders by a pipe fitted
with the usual stop valve, and also with a throttle valve. The throttle-valve
spindle has fast on it a lever which is connected by a link to the hand lever by
which the clutch is worked, the arrangement being such that when the hand lever
is moved to take the clutch out of gear it at the same time closes the throttle valve
to a greater or less extent. With this improved arrangement whilst racing of the
crank shaft and waste of steam are prevented, the attendant workman has only
the one hand lever to attend to in addition to the foot lever by which the brake
strap is made to act on the winding barrel.

page_text: I, DAVID DEHANE NAPIER, of 100 Hyde Park Street, Glasgow, in the County
of Lanark, North Britain, 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, that is to say :-
My said Invention has for its object the construction of a simple and compact
steam winch to serve as a cargo whip, and it comprises arrangements for controlling
the action of the steam in connection with the clutch through which the winding
barrel is driven. And my Invention consists in connecting the throttle-valve lever
to the clutch lever so as by one action to adinit and shut off the steam when
moving the clutch into or out of gear.
And in order that my said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing my improved steam cargo whip or winch.
Figure, 1, is an end elevation and figure, 2, is a side elevation of the whip
or winch.
A bed plate, 3, has on it two steam cylinders, 4, driving a crank shaft, 5, which
has on it a worm (not shown) driving a worm wheel, 6, on the shaft, 7, of the
winding barrel, 8. The winding barrel, 8, is loose on its shaft, 7, and is driven
from it by means of an ordinary engaging and disengaging clutch, 9, made with
a groove in its outer end in which pins, 10, engage, these pins being fixed in a
hand lever, 11, the lower end of which is forked and centered on a bracket, 12,
formed on the end standards, 13. When the hand lever, 11, is moved it moves
the clutch, 9, into or out of gear. Steam is supplied to the two cylinders, 4, by
a pipe, 14, fitted with the usual stop valve, 15, and also with a throttle valve, 16.
The throttle valve spindle, 17, has fast on it a lever, 18, which is connected by a
link, 19, to the hand lever, 11, by which the clutch, 9, is worked and in consequence
of this arrangement when the hand lever, 11, is moved to move the clutch into or
out of gear it at the same time opens or closes the throttle valve. With this
improved arrangement whilst racing of the crank shaft, 5, and waste of steam are
prevented the attendant workman has only the one hand lever to attend to in
addition to the foot lever, 20, by which the brake strap, 21, is made to act on the
winding barrel, 8.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
In steam cargo whips or winches, connecting the lever of the throttle valve to
the hand lever by which the clutch is worked substantially as and for the purposes
hereinbefore described.
