PROVISIONAL SPECIFICATION.
Improvements in Obtaining Power for Operating Steering Gear,
Pumps, Winches, and similar Gear used on Board Ship.
I, WILLIAM THOMSON of Smith Street, Kinning Park, Glasgow, Engineer do hereby
declare the nature of this Invention to be as follows:-
This invention has mainly for its object to utilize power derivable from the move-
ment through the water and air of ships and other sailing vessels or from the
propeller or paddle shafts of steamers for operating steering gear, pumps, winches,
windlasses, and like gear on board ship.
For such purposes I place, in the case of sailing vessels, a turbine, wator wheel or
other water or air motor in any suitable position in the vessel where the said motor
may be actuated by the movement of the water or air relatively with the vessel, a pipe
duct or channel being preferably carried longitudinally through the vessel and the
motor placed at any convenient point in it so that the water flowing through it whilst
the vessel is under way actuates the motor. The power of the motor is transmitted
to the steering gear through any suitable gearing, clutches or other mechanism being
used for obtaining reversing movements, or the water duct or channel may be
divided and a valve provided for so directing the water to one side or other of the
motor as to obtain movement in either direction or so as to act on either of two
motors arranged to be rotated in opposite directions.
In the case of steam ships I obtain the requisite power for operating the steering
gear, pumps or the like from the propeller. shaft or paddle shaft, or from any other
shaft operated by the driving engines, through shafting and gearing which are put into
action by means of friction or other clutches or like mechanism.

COMPLETE SPECIFICATION.
Improvements in Obtaining Power for Operating Steering Gear,
Pumps, Winches, and similar Gear used on Board Ship.
I, WILLIAM THOMSON of Smith Street, Kinning Park, Glasgow, 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:-
This Invention has mainly for its object to utilize power derivable from the move-
ment through the water and air of ships and other sailing vessels or from the
propeller or paddle shafts of steamers for operating steering gear, pumps, winches
windlasses and like gear on board ship.
For such purposes I place, in the case of sailing vessels, a turbine, water wheel or
other water or air motor in any suitable position in the vessel where the said motor
may be actuated by the movement of the water or air relatively with the vessel, a
pipe duct or channel being preferably carried longitudinally through the vessel and
the motor placed at any convenient point in it so that the water flowing through it
whilst the vessel is under way actuates the motor. The power of the motor is
transmitted to the steering gear through any suitable gearing, clutches or other
mechanism being used for obtaining reversing movements, or the water duct or
channel may be divided and a valve provided for so directing the water to one side

or other of the motor as to obtain movement in either direction or so as to act on
either of two motors arranged to be rotated in opposite directions.
In the case of steam ships obtain the requisite power for operating the steering
gear pumps or the like from the propeller shaft or paddle shaft, or from any other
shaft operated by the driving engines, through shafting and gearing which are put
into action by means of friction or other clutches or like mechanism.

In the accompanying drawings which in part illustrate my invention, figures 1 and
2 are elevations showing steering gear for a sailing vessel as arranged to be operated
by the water through which the vessel moves figure 3 is a part plan of figure 2.
Figure 4 is an elevation showing one arrangement for operating the steering gear
from the propeller shaft or paddle shaft of a steamer and figure 5 shows a modification
of the same as adapted for the gear shown in figure 1. Figures 6 to 10 a reviews of
sailing vessels showing a few of the many arrangements applicable for obtaining
power from the movement of the vessels through the water to operate the steering
gear.
་
The steering gear employed may be of any well known construction that represented
in the drawings being of the type described in the Specification of my Patent No. 885
of 1873 in which the handing wheel A, is on a shaft B, having on it a worm or
screw C, gearing with worm wheels D, on vertical shafts E, whereon are pulleys F,
round which the rudder chains are passed. The handing wheel is in the present
instance fitted loose on the shaft B, but is adapted to slide and be made fast thereon
by a key and feather b, or like means so that the handing wheel may be used to
operate the gear when desired. On the worm shaft B, in the example shown at
figure 1 a pair of bevel wheels G, G¹, are secured and fitted to slide on a key
way 9, when acted on by a lever H, so as to bring either or neither into gear
with a bevil pinion G2, on a vertical shaft I, which is driven by a turbine or other
water motor J, and whereby the power of the said motor is applied to drive the
worm shaft of the steering gear in either direction. The motor J, is operated by
water entering by the pipe K, and flowing out by the pipe K¹, the power obtained
being due to the movement of the water relatively with the vessel sailing through
it. In the example represented at figures 2 and 3 power is transmitted to the shaft B
of the steering gear to drive it in one direction only by means of bevel wheels G, G',
on the shafts B, and I, a lever H, operating a disconnecting clutch or like means,
being provided for throwing the shafts or wheels out of gear. The vertical shaft I,
is driven by gearing L, from the axle shaft of a duplex water motor which is driven
in either direction according as water is led to it by one or other of two pipes K, K¹,
the vanes of the motor being set in opposite directions. The flow of the water
which is led in from the ship's side by a pipe K2, is directed to either delivery
pipe K, or K¹, by means of a valve k, operated by a spindle k', and lever k³, within
reach of the man at the wheel whilst the tail race is formed by a pipe k³, leading
towards the stern of the vessel. Many other well known arrangements of mechanism
may be employed for transmitting the power of the water or of the air to operate the
steering gear.
As represented at figures 6 and 7, pipes on each side of the vessel may be lowered
into the water or as shown at figures 8 and 9 wheels or paddles may be lowered from
each side of the vessel to transmit power by means of belts or gearing to operate the
steering gear. Or as shown at figure 10 valves may be opened on either side of the
vessel to open water ways leading to the motor or motors in which case one valve
may admit water to drive the motor in one direction and the other to drive the motor
in the opposite direction.
For operating the steering gear from the propeller shaft or the paddle shaft of a
steamer an arrangement such as that represented at figure 4 may be conveniently
employed. In this case open and cross belts M, M', are passed over fast and loose
pulleys N, N', on the shaft B, of the steering gear and driven from a drum O, on the
propeller or paddle shaft P, the belts being shifted as required to operate the steering
gear in either direction by means of belt forks Q, and a hand lever Q¹. Or as shown

page_text: at figures 1 and 5 the shaft I, may be driven by gearing R, R', from the propeller or
paddle shaft P.
The steering gear represented in the drawings may be replaced by pumps, winches
or like gear to be operated by power obtained as above described.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The adaptation for operating steering gear, pumps winches and like gear
on board ship, of power obtained from the movement of the vessel substantially as
herein before described.
2. The adaptation in steamships of means for operating steering gear, pumps,
winches and like gear from the propeller shaft or paddle shaft substantially as
hereinbefore described.
3. The several arrangements of mechanical devices hereinbefore described with
reference to the accompanying drawings for obtaining power for operating steering
gear pumps winches and like gear on board ship.
