Improvements in or connected with Ships' Telegraphic Apparatus.
I, HEDLEY OLIVER, of 6 Tower Chambers, Water Street, Liverpool, in the
County of Lancaster, Engineer do hereby declare the nature of this invention to
be as follows:-
This invention has reference to ships telegraphic apparatus, and more especially
to telegraphic apparatus employed for communicating between the bridge and
engine room of a steam ship; and it has more particularly for its object to provide
improvements in connection with "tell-tale" communications as regards the setting
of the engine, and actions actually performed by it, special applicability or utility
being claimed for it where ships are being docked, un-docked, or similarly handled,
or being sailed under special conditions or orders.
According to this invention, "tell-tale " telegraphic actions are automatically
transmitted to the transmitting instrument on the bridge-or similar post or
position, or to a separate instrument thereon, by which the different rates and
directions at which the engine is set to go by the engineer or attendant, is ascer-
tained and indicated; as for instance as to whether the engines are set to go "slow,"
"half speed," "full speed," or at other rate, and whether "ahead or astern,
and thus every alteration of the mechanism by which the rate of the engine is set to
act is automatically shewn.
"
,,
"
A means of effecting the actions and effects above specified, consists of a
mechanism connected with the means of supplying steam to the engine, or
controlling the supply of steam thereto, as the ordinary supply, or stop valve,
which, through a suitable mechanism operates telegraphic apparatus (say in or on
the engine room "receiver") and transmits it to the bridge, where it is indicated,
and whereby the degree of operation and setting of such valve or part, and the rate
at which the engine will be set to run thereby, will be automatically telegraphed
and seen by the captain, or other, in charge of the ship, or at the bridge
instrument.
In the case of the motion or movement of the stop or equivalent valve of the
engine being used to obtain the action referred to, its movement and setting would
be transmitted by its actuating shaft or spindle directly through worm, toothed, or
equivalent gearing, to the engine room telegraphic apparatus; or, indirectly
through such mechanism, or other mechanism, thereto; and so, by chains or other
known meaus, to the instrument on the bridge or other position, where it will be
indicated or seen. By this, every movement of the valve would be communicated
and indicated. To indicate as to whether these movements are made with the
engine set to go ahead,” or “astern," the said mechanism is provided with reversing
gear, so as to operate the telegraphic apparatus in the one direction or the other;
and such reversing gear would be actuated automatically from the engine, as from
a part of the reversing gear or mechanism thereof.

I, HEDLEY OLIVER, of 6 Tower Chambers, Water Street, Liverpool, in the
County of Lancaster, 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 reference to ships telegraphic apparatus, and more especially
to telegraphic apparatus employed for communicating between the bridge and
engine room of a steam ship; and it has more particularly for its object to provide
improvements in connection with "tell-tale" communications as regards the setting
of the engine, and actions actually performed by it, special applicability or utility
being claimed for it where ships are being docked, un-docked, or similarly handled,
or being sailed under special conditions or orders.
According to this invention, "tell-tale" telegraphic actions are automatically
transmitted to the transmitting instrument on the bridge-or similar post or
position, or to a separate instrument thereon, by which the different rates and
directions at which the engine is set to go by the engineer or attendant, is ascer
tained and indicated; as for instance as to whether the engines are set to go "slow,"
"half speed," "full speed," or at other rate, and whether "ahead
astern,"
and thus every alteration of the mechanism by which the rate of the engine is set
to act is automatically shewn.

or
A means of effecting the actions and effects above specified, consists of a
mechanism connected with the means of supplying steam to the engine, or
controlling the supply of steam thereto, as the ordinary supply, or stop valve,
which, through a suitable mechanism operates telegraphic apparatus (say in or on
the engine room "receiver"), and transmits it to the bridge, where it is indicated,
and whereby the degree of operation and setting of such valve or part, and the rate
at which the engine will be set to run thereby, will be automatically telegraphed
and seen by the captain, or other, in charge of the ship, or at the bridge
instrument.
In the case of the motion or movement of the stop or equivalent valve of the
engine being used to obtain the action referred to, its movements and setting would
be transmitted by its actuating shaft or spindle directly through worm, toothed, or
equivalent gearing, to the engine room telegraphic apparatus; or, indirectly
through such mechanism, or other mechanism, thereto; and so, by chains, shafting
and bevel wheels, or other known means, to the instrument on the bridge or other
position, where it will be indicated or seen. By this, every movement of the valve
would be communicated and indicated. To indicate as to whether these movements
are made with the engine set to go ahead," as "astern," the said mechanism is
provided with reversing gear, so as to operate the telegraphic apparatus in the one
direction or the other; and such reversing gear would be actuated automatically
from the engine, as from a part of the reversing gear or mechanism thereof.

The drawings hereto annexed are illustrative of this invention. There is shewn
in these drawings an ordinary receiving instrument of an engine telegraph, worked
by the usual chain gearing, with my improvements applied in connection with it.
The apparatus shewn in connection with the receiving instrument is adapted to
operate through chains or other suitable means, a pointer or indicator in connection
with bridge telegraphic apparatus of the usual or any known suitable kind.
In these drawings Figure 1 is a front elevation, and Figure 2 a plan, shewing the
invention applied in connection with an engine, and adapted to be actuated and
controlled by a wiper or reversing shaft of the engine, and the spindle or shaft by
which the throttle or supply valve is actuated. Figures 3 and 4 are side elevation,

page_text: partly in section, and plan, partly in section, shewing the mechanism within the
receiving instrument.
Referring now to the drawings, a is one of the columns of an engine; 6 is the
reversing or wiper shaft of the engine; and c is the valve rod or spindle, moved up
and down by the hand wheel c', by which the throttle or steam supply valve of the
engine is actuated. designates generally the receiving instrument, as shewn,
which, is mounted on the column a; and e is a lever, fulcrummed at e', by which the
movement of the valve spindle c is transmitted to the spindle f, which actuates the
mechanism within the instrument d; whilst the mechanism within the instrument,
by which the indication as to the direction in which the engine is set to run, or is
running, is effected by the parts consisting of the aring on the reversing shaft 1,
the connecting bar g', an arm 92, and a shaft g3 passing into the instrument d. By
these two means of employing the movement of the throttle valve spindle and the
wiper shaft to act upon mechanism and indicate at the bridge instrument, in the
manner desired, the speed and direction of movement the engine is running, or set
to run, is effected.
Referring now to the mechanism in the instrument d, and shewn more particularly
in Figures 3 and 4, on the spindle f, within the instrument d, there is provided a
slow or long pitched threaded part h, while outside this part, and meshing with it,
there is an internally threaded sleeve or part i; and again outside this sleeve is a
further sleeve k, on which is formed or mounted upper and lower bevel wheels 7, the
sleeve being free to be moved up and down over i, but fixed with i as regards
axial movement through the key m, part of which lies within a recess or keyway
in i, and part in k. The spindle f, and by it the parts surrounding it, is supported
at the top of the instrument by the neck or bush n, and below by a neck n', this
latter neck, and that part of the shaft which works in it, being rectangular or
polygonal in form to prevent the said shaft and screw from turning when raised
and lowered. The chain wheel, through which motion of this mechanism is trans-
mitted to the pointer on the bridge transmitting instrument, is desiguated o, it
having on one side of it a bevelled circular rack o' in connection with which one or
other of the wheels is adapted to gear. To put either the upper or the lower of
the wheels in gear with the rack o', the sleeve k on which the wheels are mounted,
is moved up or down on the sleeve i, this being effected by the yoke or bifurcated
arm p, which is fastened on the shaft g3 (which is operated as above described),
and has its ends disposed between and acting in connection with the flanges k¹ on
the sleeve k. The wheel 9 shewn in Figure 3 is that by which the indicating
pointer of the instrument d is operated from the transmitting instrument, as usual.
In action, two notifications are automatically transmitted to the bridge instrument
in charge of the captain, or other person in charge of the ship, by this apparatus ;
namely, the rate of speed at which the engine is set to run or is running, and the
direction in which the engine is set to run or is running. The latter of these is
performed by the connecting parts g g' g² 93, the arm p, the sleeve k, and one of
the bevel wheels /. When the engine is set to run in one direction, the upper
wheel will be in gear with o¹, whilst when the engine is set to run in the reverse
direction, the upper wheel will, by the gear specified, be put out of gear with o',
whilst the lower wheel will be put in gear with it. Thus, according to which
wheel is in gear, so will be the direction in which the communication chain, cord,
or the like, on the wheel o is moved, when the sleeve is rotated. The first of
these actions is effected through the shaft c, lever e, shaft and the threaded part h
thereof, and the sleeve i; and according to the position to which the valve which
controls the supply of steam to the engine, and its actuating shaft c, so will be the
rod pressed up and down, and the sleeve i, and thereby the sleeve k, and the
wheels, rotated. That is, when the said valve is opened by the movement of
the shaft c through the wheel ', according to the amount of such opening, the
shaft will be moved more or less up and down, and the threaded part lifted or
moved bodily through sleeve i by the lever e, and by this movement of the parth,
the sleeve, and through it the shaft and bevel wheels 1, are rotated, and the

page_text: wheel o moved. Assuming, then, the transmitting instrument to be provided with
an indicator or pointer, and connected by a chain or the like with the wheel o, as
this wheel o is moved in one direction or the other by the movement up and down
of the part from the rod c, so will the said pointer be moved over the face of the
dial of the transmitting instrument, and shew or indicate upon it the rate of speed
at which the engines will be running.
The application of the invention in the manner set forth with reference to the
drawings, is a convenient one, and well suited to many cases of marine engines.
It is, however, not restricted to these, but may, by simple modifications or adaptations,
be applied in different ways to suit the differing circumstances or conditions of its
application, or to meet special cases.
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 :-
1. In ships telegraphic systems, effecting substantially as in the manner described,
the indication at the bridge or other desired part, the speed at which the engines
are running or set to run, by means of a part connected with or actuated by a valve
that controls the supply of steam to the engine, and suitable mechanism for
transmitting the movement thereof to the said indicating instrument.
2. In ships' telegraphic systems, effecting, substantially as in the manner
described, the indication at the bridge or other desired part, the speed at which the
engine is set to run or is running, and also the direction in which the engine is
running or set to run, by means of a part connected with or actuated by a valve
that controls the supply of steam to the engine, and suitable mechanism for
transmitting the movement thereof to the said indicating instrument, and by a
means operated from the reversing gear of the engine, or part connected therewith.
by which the aforesaid mechanism operated by the said valve is adapted to
transmit the said movement thereof to the indicating apparatus, so as to shew the
direction of movement of the engine, as well as its speed.
3. In apparatus for transmitting from an engine room to the bridge or other
part of a ship the rate of speed at which the engine is running or is set to run, and
the direction in which it is running or set to run, the employment, in connection
with the steam supply controlling valves actuating spindle or rod, of a screw or
threaded part working in connection with another threaded part, and so adapted
that when the one is moved longitudinally, the other receives rotative movement,
and that movement is conveyed through means such as specified, to the indicating
apparatus at the bridge or other part; substantially as herein set forth with
reference to the drawings.
4. The mechanisms for use in connection with ships telegraphic apparatus for
indicating at the bridge or other place the rate of speed at which the engine is
moving or is set to move, and the direction of such movement, particularly as set
forth with reference to and shewn in the drawings.
