We, WILLIAM CLARKE and JOHN BROKENSHIRE FURNEAUX, both of Nos. 9 and 11,
Fenchurch Avenue, in the City of London, Engineers, do, hereby declare the nature
of this invention to be as follows:-
Our invention has reference to steering gear such as may under certain arrange-
ments be used for steering by manual power or by other power such as that of steam,
or according to another arrangement may be employed for steering by the latter only.
In one arrangement the apparatus comprises a shaft we will call the steering wheel
shaft, a counter shaft, and a steering chain shaft. On the steering chain shaft is an
internally toothed wheel we will call the main spur wheel, and in gear therewith is a
pinion fixed on the steering wheel shaft. The last mentioned shaft has mounted
freely upon it a worm wheel in gear with a worm that can be driven by a motor
engine, the controlling valve of which is operated from the steering wheel shaft
through spur gear, one of the spur pinions being made as a nut fitting a quick threaded
screw forming part of the counter shaft. Upon the steering wheel shaft is arranged
a spur wheel in gear with the screw pinion. This spur wheel is formed with or
attached to a sleeve forming part of a clutch keyed upon the steering wheel shaft, but
movable lengthwise thereon in such a way that it can be placed in gear either with
part of a clutch formed with or attached to the before mentioned worm wheel, or in
gear with part of a clutch formed with or attached to a second sleeve upon which the
steering wheel is mounted. This second sleeve also carries or has attached to it a
spur wheel in gear with a second spur pinion on the counter shaft. The two spur
wheels on the steering wheel shaft are alike in diameter and number of teeth, and the
two spur pinions on the counter shaft are alike in diameter and number of toeth.
Upon the counter shaft there is formed a screw of finer pitch than that previously re-
ferred to, and this screw of finer pitch works an indicator as the counter shaft is rotated,
indicating the position of the tiller. With the arrangement just described, if it be
desired to steer by means of the engine, the movable sleeve is placed into gear with
the worm wheel on the steering wheel shaft, and on the steersman turning the steering
wheel, the sleeve that carries that wheel, and the spur wheel formed with or attached
to it, will revolve correspondingly and turn the counter shaft by means of the spur
pinion keyed on that shaft that is in gear with the spur wheel of the steering wheel.
The turning of the counter shaft will move the other spur pinion forward or backward

page_text: by means of the quick threaded screw on which it is threaded, as at this time the last
mentioned pinion will be held from turning by the spur wheel on the movable sleeve
or clutch, which for the moment will be at rest. The sliding of the pinion will
actuate the controlling valve of the engine, and the engine will at once be started.
The engine shaft rotating will drive the worm and actuate the worm wheel on the
steering wheel shaft, which being in gear with the movable sleeve (keyed upon the
steering wheel shaft) will rotate the pinion in gear with the main spur wheel on
the steering chain shaft. Whilst the steersman continues to rotate the steering wheel,
the engine will be kept in motion; but on the steersman ceasing to rotate the steering
wheel, the counter shaft will be held steady, and the movement of the engine will run
back the screw pinion to its normal position, bringing with it the controlling valve to
its mid position, and stopping the engine.
For steering by manual power, the movable sleeve is placed in gear with the
steering wheel sleeve, and thus the power of the steersman on the steering wheel is
transmitted through the shaft to the pinion fixed thereon, and through it to the main
spur wheel on the steering chain shaft. While thus steering by hand power, the
counter shaft will still be rotated, but the screw or sliding pinion connected to the
controlling valve will not be moved on its screw; it will turn simply with the counter-
shaft, and will not actuate the controlling valve of the engine. The rotation of the
counter shaft, whether for hand or power steering, will always move backward or
forward, the indicator nut threaded upon the finer pitched screw thus indicating the
position of the ships helm.
With apparatus as described we obtain a continuous action of the indicator of the
position of a vessel's helm without liability to any disarrangement taking place when
changing from steam to hand, or vice versâ ; and it will be seen that such changes
can be readily effected simply by the movement of a single sleeve or clutch-piece.
Apparatus as described may be arranged with a vertical engine or with a horizontal
engine.
According to one modification, the movable sleeve or clutch-piece is formed without
a spur wheel, the spur wheel being fixed upon the steering wheel shaft at the other
side of the worm wheel. The engine employed may be of any suitable construction
simple or compound. According to another modification for power steering only the
valve mechanism is differently arranged. The shaft carrying the steering wheel is in
gear with another shaft we will call the vertical shaft. On this is mounted a sleeve
formed with an annular groove or flanges, and with a worm. This worm is in gear
with a
worm wheel mounted on the steering chain shaft. The spindle of the
controlling valve is provided with a fork, or equivalent means that engages with the
annular groove around the sleeve. The arrangement is such that on the steersman
causing the vertical shaft to rotate, the sleeve thereon will be either raised or depressed
by being rotated whilst its worm is in gear with the worm wheel, which at this time
will be at rest, and the upward or downward movement of the sleeve will produce
corresponding movement of the controlling valve by means of the fork held in the
groove of the sleeve; thus the engine will start.
So long as the steersman continues to rotate the vertical shaft, the engine will
continue working in the desired direction; but immediately the rotation of the
vertical shaft ceases, the sleeve, being no longer rotated, will be slid back into its
normal position by the worm wheel acting as a driver, thus bringing the controlling
valve to the mid position, and stopping the engine. Thus it will be understood that
with this arrangement of mechanism the controlling valve is actuated by the
steersman to start, and by the steering chain shaft to stop, the engine. The steering
wheel shaft is or may be formed with a screw thread to work an indicator.

page_text: We WILLIAM CLARKE and JOHN BROKENSHIRE FURNEAUX both of Nos. 9 and 11
Fenchurch Avenue in the City of London, Engineers, 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:-
Our Invention has reference to steering gear such as may under certain arrange-
ments be used for steering by manual power or by other power such as that of steam,
or according to another arrangement may be employed for steering by the latter only.
In one arrangement the apparatus comprises a shaft we will call the steering wheel
shaft, a counter shaft, and a steering chain shaft. On the steering chain shaft is an
internally toothed wheel we will call the main spur wheel, and in gear therewith is a
pinion fixed on the steering wheel shaft. The last mentioned shaft has mounted freely
upon it a worm wheel gear with a worm that can be driven by a motor engine, the
controlling valve of which is operated from the steering wheel shaft through spur
gear, one of the spur pinions being made as a nut fitting a quick threaded screw
forming part of the counter shaft. Upon the steering wheel shaft is arranged a spur
wheel in gear with the screw pinion. This spur wheel is formed with or attached to
a sleeve forming part of a clutch keyed upon the steering wheel shaft, but moveable
lengthwise thereon in such a way that it can be placed in gear either with part of a clutch
formed with or attached to the before mentioned worm wheel, or in gear with part of
a clutch, formed with or attached to a second sleeve upon which the steering wheel is
mounted. This second sleeve also carries or has attached to it a spur wheel in gear
with a second spur pinion on the counter shaft. The two spur wheels on the steering
wheel shaft are alike in diameter and number of teeth, and the two spur pinions on
the counter shaft are alike in diameter and number of teeth. Upon the counter shaft
there is formed a screw of finer pitch than that previously referred to, and this screw
of finer pitch works an indicator as the counter shaft is rotated, indicating the position of
the tiller. With the arrangement just described, if it be desired to steer by means
of the engine, the movable sleeve is placed into gear with the worm wheel on the
steering wheel shaft, and on the steersinan turning the steering wheel, the sleeve that
carries that wheel, and the spur wheel formed with or attached to it, will revolve
correspondingly and turn the counter shaft by means of the spur pinion keyed on that
shaft that is in gear with the spur wheel of the steering wheel. The turning of the
counter shaft will move the other spur pinion forward or backward by means of the

page_text: quick threaded screw on which it is threaded, as at this time the last mentioned pinion
will be held from turning by the spur wheel on the movable sleeve or clutch, which
for the moment will be at rest. The sliding of the pinion will actuate the controlling
valve of the engine, and the engine will at once be started. The Engine shaft rotating
will drive the worm and actuate the worm wheel on the steering wheel shaft, which
being in gear with the movable sleeve (keyed upon the steering wheel shaft) will
rotate the pinion in gear with the main spur wheel on the steering chain shaft. Whilst
the steersman continues to rotate the steering wheel, the engine will be kept in motion;
but on the steersman ceasing to rotate the steering wheel, the counter shaft will be
held steady, and the movement of the engine will run back the screw pinion to its
normal position, bringing with it the controlling valve to its mid position, and stopping
the engine.
For steering by manual power, the movable sleeve is placed in gear with the steering
wheel sleeve, and thus the power of the steersman on the steering wheel is transmitted
through the shaft to the pinion fixed thereon, and through it to the main spur wheel
on the steering chain shaft. While thus steering by hand power, the counter shaft
will still be rotated, but the screw or sliding pinion connected to the controlling valve
will not be moved on its screw; it will turn simply with the countershaft, and will not
actuate the controlling valve of the engine. The rotation of the counter shaft, whether
for hand or power steering, will always move backward or forward, the indicator nut
threaded upon the finer pitched screw thus indicating the position of the ship's helm.
With apparatus as described we obtain a continuous action of the indicator of the
position of a vessel's helm without liability to any disarrangement taking place when
changing from steam to hand, or vice versa ; and it will be seen that such changes
be readily effected simply by the movement of a single sleeve or clutch piece.
Apparatus as described may be arranged with a vertical engine or with a horizontal
engine.
can
According to one modification, the movable sleeve or clutch piece is formed without
a spur wheel, the spur wheel being fixed upon the steering wheel shaft at the other
side of the worm wheel. The engine employed may be of any suitable construction
simple or compound. According to another modification for power steering only the
valve mechanism is differently arranged. The shaft carrying the steering wheel is in
gear with another shaft we will call the vertical shaft. On this is mounted a sleeve
formed with an annular groove or flanges, and with a worm.
This worm is in gear
with a worm wheel mounted on the steering chain shaft. The spindle of the controlling
valve is provided with a fork, or equivalent means that engages with the annular
groove around the sleeve. The arrangement is such that on the steersman causing the
vertical shaft to rotate, the sleeve thereon will be either raised or depressed by being
rotated whilst its worm is in gear with the worm wheel, which at this time will be at
rest, and the upward or downward movement of the sleeve will produce corresponding
movement of the controlling valve by means of the fork held in the groove of the
sleeve; thus the engine will start.
So long as the steersman continues to rotate the vertical shaft, the engine will
continue working in the desired direction; but immediately the rotation of the vertical
shaft ceases, the sleeve, being no longer rotated, will be slid back into its normal
position by the worm wheel acting as a driver, thus bringing the controlling valve to
the mid position, and stopping the engine. Thus it will be understood that with this
arrangement of mechanism the controlling valve is actuated by the steersman to start,
and by the steering chain shaft to stop, the engine. The steering wheel shaft is or
may be formed with a screw thread to work an indicator.
Referring to the annexed illustrative drawings
Figure 1, Sheet 1, shows an arrangement according to this Invention for steering
by manual power or by other power, such as that of Steam.
A is a shaft which we will call the Steering wheel Shaft. This shaft A has mounted
freely upon it a worm wheel F in gear with a worm G which can be driven by a motor
Engine, B is a Countershaft and a steering chain shaft. When it is desired to steer
by Steam the clutch M is placed in gear with clutch on worm-wheel F.

page_text: On the steering chain shaft C an internally toothed wheel D is keyed and in gear
therewith a pinion E is keyed to the steering wheel-shaft A.
On the steering wheel shaft A, a steering wheel I is freely mounted, having on its
centre boss a clutch gearing into the back of a bevel pinion K which is keyed fast to
a clutch sleeve L, mounted freely on the steering wheel shaft, A. Between this clutch
sleeve L and the worm-wheel F, a sliding clutch M is mounted upon two keys or
feathers in the shaft A and is so arranged as to be placed into gear with either the
clutch F or the sleeve L as may be desired.
The countershaft B has mounted upon it two pinions, one lettered N being threaded
on to a screw cut at this end of the countershaft, and gearing into the wheel O, cast
or keyed onto the sliding clutch M. The other pinion P, is keyed on this Counter-
shaft B and gears with the wheel Q on the clutch-sleeve L.
The mode of operating the controlling valve for steering by steam or other motive
power is as follows:
On the Steersman rotating the steering wheel I, he turns the sleeve L, and the
wheel Q, consequently rotates the pinion P and the countershaft B which forces the
pinion Neither forward or backward according to the direction of rotation. The
controlling valve H is coupled to the pinion N by the link R or its equivalent, and is
moved either forward or backward by the pinion N and the Engine started in one
direction or the other. So long as the Steersman continues to rotate the steering-
wheel I, the Engine will continue its movement, but on his ceasing the countershaft B
becomes stationary and as the Engine continues its movement, the motion of the
worm-wheel F is transmitted to the wheel O by the clutch M, and to the pinion N,
causing it to screw itself back until the controlling valve is closed and the Engine
stopped.
When it is desired to steer by hand-power, the clutch M is withdrawn from the
clutch of the worm-wheel F and placed into gear with the clutch of sleeve L, the
manual purchase being thus transmitted directly along the shaft A to the pinion E
and so to the steering chains on barrel S. While thus steering by hand-power, the
countershaft will still be rotated, but the screw or sliding pinion N connecting to the
controlling valve will not be moved on its screw as it will turn simply with the counter-
shaft and will not actuate the controlling valve of the engine. The countershaft.
whether used for hand or power-steering will always move the indicator nut T
backward or forward upon the fine-pitched screw of the countershaft, thus indicating
the position of the Ship's helm.
With apparatus as described we obtain a continuous action of the indicator of the
position of a vessel's helm without liability to any disarrangement taking place when
changing from Steam to hand or vice versa and it will be seen that such changes can
be readily effected simply by the movement of a single sleeve or clutch piece.
Apparatus as described may be arranged with a vertical engine or with a horizontal
Engine.
Figure 2 Sheet 2 shews an arrangement for power steering only and wherein the
valve mechanism is differently arranged. The shaft A carrying the steering wheel B
is in gear with another shaft C. On this shaft C is mounted a sleeve or controlling
valve D formed with annular grooves or flanges and below this is keyed a worm E.
This worm E is in gear with a worm wheel F keyed to the steering chain shaft G. The
spindle C of the controlling valve D is carried into a Bevel pinion H and fitted with
a feather engaging in a keyway cut in this pinion, but the spindle C is free to move
longitudinally in this pinion. The arrangement is such that on the Steersman causing
the vertical shaft C to rotate the controlling valve D thereon will be either raised or
depressed by the action of the worm E which is in gear with the worm wheel Fas
with a half nut. At this time the worm wheel will be at rest and the upward or
downward movement of the controlling valve D will produce corresponding movement
of the engine.
So long as the steersman continues to rotate the vertical shaft C the engine will
continue working in the desired direction, but immediately the rotation of the vertical
shaft C ceases the controlling valve D will be slid back into its normal position by the

page_text: worm wheel F acting as a driver and thus the controlling valve D will be brought to
mid position and the engine stopped. Thus it will be understood that with this
arrangement of mechanism the controlling valve D is actuated by the steersman to
start and by the steering chain shaft G to stop the engine. The steering wheel shaft A
is or may be formed with a screw thread to work an indicator.
Having now particularly described and ascertained the nature of the said
Invention and the manner of carrying the same into practical effect we declare
that what we claim is,
First. The improved hand and power steering gear substantially as described with
reference to Sheet 1 of the Drawings.
Secondly. The improved power steering gear substantially as described with
reference to Sheet 2 of the Drawings.
