page_text: I, ANDREW BETTS BROWN, of the Rosebank Iron Works, Edinburgh, in the
County of Mid Lothian, North Britain, Engineer, do hereby declare The nature
of this invention to be as follows, that is to say:-
My said invention relates to steering machinery partly of the kind described
in my Patent Specification, No. 10,132 of 1889; and comprises improved arrange-
ments or combinations suitable for large warships and other steamers.
In place of an encased engine being mounted on the tiller, I arrange two similar
engines in the steering compartment, on the port and starboard sides, these engines
driving transverse shafts which have on them worms gearing with worm wheels
on a fore-and-aft shaft between them, the worm wheels being fitted with friction
clutches capable of being tightened or slackened by means of handwheels.
On the after end of the fore-and-aft shaft there is a sprocket wheel which acts
on a pitch chain which passing round pulleys at the sides is connected to a block
fitted to slide in a transverse guide; and the block acts on the tiller which passes
through a slot in it.
On the fore end of the fore-and-aft shaft there is a friction clutch and worm-
wheel which is in gear with a worm on a shaft geared by bevil wheels to a fore-
and-aft shaft having on it four or other required number of hand steering wheels.
The valve gear of the engines is operated from four steering stations by means
of four telemotors, each of which has a motor cylinder in the steering compart-
ment. An independent pair of pipes connects each telemotor from the steering
stations to the motor cylinders; whilst a series of stop valves is fitted in connection
with the telemotor pipes, to allow of any motor cylinder being put in connection
with the transmitter at any one of the steering stations. Similarly, a series of
levers and connections is provided for putting any one of the motor cylinders
in connection with the valve gear of either of the engines.
Dated this Eleventh day of October 1897.

I. ANDREW BETTS BROWN, of The Rosebank Iron Works, Edinburgh, in the
County of Mid Lothian, North Britain, Engineer, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement, that is to say:-
My said invention relates to steering machinery partly of the kind described
in my Patent Specification, No. 10,132 of 1889; and comprises improved arrange-
ments or combinations suitable for large warships and other steamers.

page_text: In place of an encased engine being mounted on the tiller, I arrange two similar
engines in the steering compartment, on the port and starboard sides, these engines
driving transverse shifts which have on them worms gearing with wormwheels
on a fore-and-aft shaft between them, the worm wheels being fitted with friction
clutches capable of being tightened or slackened by means of handwheels.
The valve gear of the engines is operated on from two, three, or more separate
steering stations, by telemotor apparatus acting by means of receiving cylinders
in the steering compartment in connection with the valve gear of the engines.
An independent pair of pipes connects each transmitting cylinder at a steering
station with the receiving cylinders in the steering compartment, whilst a series
of slop valves is fitted in connection with the telemotor pipes to allow of the
transmitting cylinder at any steering station being put in connection with either
or any receiving cylinder in the steering compartment. Similarly, a series of
lovers and connections is provided for putting either or any of the receiving
cylinders in connection with the valve gear of either of the engines, whilst gearing
and lever connections are also provided for acting on the valve gear by means
of handwheels, there being also genring for turning the fore-and-aft shaft from
large hand steering wheels, if required when the engines are not working.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append two sheets of explanatory drawings
showing an example of my improved steering machinery and hereinafter referred
to in describing the same.
Figure 1, on Sheet 1, of the drawings is a plan of the machinery in the steering
compartment, and Figure 2. shows parts of the same machinery in side elevation.
Figures 3, and 4, on Sheet 2, are a plan and elevation, on an enlarged scale,
showing the arrangement of stop valves and connections of the telemator pipes.
In these drawings the same reference letters and numerals are used to mark
the same or like parts wherever they are repeated.
A fore-and-aft shaft A, which is arranged to net on the tiller in the manner
described in my Patent Specification No. 7880 of 1894, or in any other suitable
known way, extends forwards between two encased steering engines B. C. shown
in Figure 1. as placed on opposite sides of a longitudinal bulk-head D. The
engines B, C, drive separate transverse crank shafts B1, C1, which have on
them worms gearing with wormwheels 12, C2, on the shaft A. but capable of
being engaged with this shaft or disengaged therefrom by means of friction
clutches B, C, acted on by handwheels B4, C4. The shaft A, has also on it
a third worm wheel E, with a frictional engaging and disengaging clutch E3.
and handwheel E4, this worm wheel E, having in gear with it a worm E1, on
a shaft E2, which by bevil wheels E5, is geared to a shaft F1, having on it
four large steering handwheels F.
The controlling valves of the steering engines B, C, are worked similarly, that
of the engine C, being moved by a lever, G (sometimes termed a floating lever)
the upper end of which is connected to a rod G 1, movable longitudinally on
pulleys (2. carried by brackets fixed to the ceiling of the upper deck, as shown
in Figure 2. The rod G1, is connected to a three-armed horizontal lever G3.
(Figure 1) one arm of which is connected by a rod G4, to a bellarank G5, and
rod G6, to a lower bellerank G 7, which is connected to the piston rod of a tele-
motor receiving cylinder II. The third arm of the lever G3, is connected by
nrod GS, and bellerank 9. to a rod 9 G, connected to a lever which is similar
to the one G, Figure 2. and acts on the controlling valve of the port steering
engine B. There are two telemotor receiving cylinders II, but in Figure 2. only
one is seen the other being directly behind. The piston rods of the two cylinders
may be connected to levers on the same rocking shaft as the bellerank G5, or
they may be connected to duplicate parts connected to the controlling valves
of the steering engines. The lever G, which moves the controlling valve of the
engine C. is jointed to a short internally screwed sleeve J. on a spindle II, the
forward end of which is screwed to work in the sleeve, its after end being acted

page_text: on through bevil wheels J 2, from a shaft J3, geared by bevil wheels J 4, to a
vertical shaft J 5, geared by bevil wheels to the fore-and-aft shaft A. In a well
understood way when the controlling valve is moved by the lever G. the consequent
operation of the steering engine and rotation of the shaft A, acts through the
parts J 5, J4, J3, J2, and J1, to move the sleeve J, and with it the lever G, so
as to return the controlling valve to its neutral position, on the desired shift of
the rudder being accomplished. The rods G 1, connected to the controlling valvo
lever G, of the starboard engine C, and the rod 9 G, connected to the similar lever
of the port engine B, are also each connected to levers 8G, on the upper ends of
vertical shafts 7 G, which can be turned by means of handwheels, 6 G, acting
through worms gearing with worm-toothed segments on those shafts.
The telemotor pipe connections and stop valves (shown in Figures 3, and 4)
are attached to a frame plate K, which is also shown in Figure 2. In the example
of apparatus shown, provision is made for operating on the steering engines from
any one of three steering stations; it is however obvious that more than three
steering stations may be arranged for in a similar way. As shown one pair of
pipes L, L, may be connected to a steering station in an after conning tower,
a second pair of pipes M, M, may be connected to a steering station at a forward
part of the lower deck, and the third pair of pipes N, N, may be connected to a
steering station in a forward conning tower. A number of stop valves in boxes P,
are connected to the telemotor pipes L, L, M, M, N, N, also to branch pipes Q.
connecting various valve boxes, and also to four pipes R, S, T, U, connected to
the two receiving motor cylinders (II) the pipes R, S, to the opposite ends of one
cylinder and the pipes T, U, to the opposite ends of the other cylinder. By
opening certain of the stop valves, the others being closed, either telemotor receiv
ing cylinder (H) can be put in communication with the telemotor transmitting
cylinder at any desired one of the steering stations. The telemotor apparatus
may, as regards its constructive details, be like any of the modifications described
in my Patent Specifications Nos. 14,456 of 1888 and 2936 of 1894.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. In steering machinery a fore-and-aft shaft, acting on the tiller, and having
on it three wormwheels, each having frictional engaging and disengaging clutches,
one with worm and bevel-wheel gearing arranged to be acted on by a shaft having on
it four or other number of steering hand wheels, and the other two arranged to
be driven by separate steering engines, preferably encased, and acting through
transverse crank shafts having worms on them in gear with the wormnwheels,
substantially as hereinbefore described.
2. In steering machinery such as that forming the subject of the First Claim,
combining therewith hydraulic telemotor receiving cylinders for acting on the
controlling valves of the steering engines, substantially as herein before described.
3. In steering machinery such as that forming the subject of the First and
Second Claims, combining the telemotor receiving cylinders at the steering
engines by means of two, three or more pairs of pipes with separate telemotor
transmitting cylinders at two, three, or more steering stations at different parts
of the ship, the several transmitting pipes being provided with stop valves and
branch pipes connecting them to the telemotor receiving cylinders near the steering
engines, substantially as herein before described.
