Complete Specification Accepted, 13th Apr., 1889
We WILLIAM FRANCE, and ROBERT MORGAN, both of Whitefield Brass Works,
Govan, Lanarkshire, Brassfounders, do hereby declare the nature of our Invention to
be as follows :—
This Invention has reference to and comprises the giving of a new and extra
distinctive telegraphic sound or alarm to the Engineer close to his receiving
instrument in the engine room in addition to the ordinary bell or gong in the
instrument for calling attention to each ordinary order when the engines have to
be reversed from "ahead" to "astern" or vice-versa, and for similarly indicating to
the helmsman or steersman when the order is given to reverse from port
to starboard or rice-versa and modes and means of doing so automatically by the
action of the instrument.
These improvements are applied on board ship to the usual reply or non-reply
telegraphic dial instruments between the Captain or Officer on the bridge and the
receiving instrument in the engine room, in which the Officer turns an outer handle
and spindle to the order on the dial he desires transmitted to the Engineers' receiving
instrument to the right or left for going "ahead" or "astern" in sectional divisions
of "stand by," "easy," "half" and "full speed," and this motion turns a corresponding
central handle on the receiving instrument in the engine room. The Engineer then
in the case of a reply instrument turns an outer handle on his receiving instrument in
like manner to the proper section to the right or left of his instrument, to give a return
message to the Captain's instrument on the bridge by a central hand on the dial to
show that he has received the particular message corresponding to that sent. These
instruments have thus two sets of duplex light chains and wire for transmitting from
the one instrument back to the other through double sets of wheels and spindles with
their respective transmitting and receiving hand pointers outside the dials. In
applying our Invention or improvements under one arrangement to this class of

instrument, the alarm would consist of a spring-bell, preferably mounted on a small
portable bracket with an actuating bell-crank lever, fulcrumed on a stud on the said
bracket having its one arm connected by a light, rigid rod to the spring hanger of
the hell, while the other free end of the bell-crank would be actuated to ring the bell
by motion in either direction from its normal position as hereinafter described.
This bracket would also have mounted on it a reciprocating rod passed through guide-
studs at the opposite ends of the bracket with a central projecting arm reciprocating
in the plane of the free end of the bell-crank, and kept in this parallel traversing
position by a light rigid wire secured to the said guides parallel to the reciprocating
rod, so that when this rod was reciprocated with its projecting arm from one side of
the free end of the bell-crank to the other, it would actuate the bellerank and ring
the bell, or this bar might be made square or flat and so work parallel in its guido
studs without the necessity for the parallel guiding wire. This bracket and its
mechanism would be mounted close to the receiving instrument in the engine room with
its reciprocating rod in the straight line of one of the line of chains transmitting the
onders from the bridge instrument to the receiving instrument in the engine room,
preferably in the vertical direction, and have the line of elmin connected to eyes or
books in the opposite ends of the reciprocating rod; all so that when the Captain or
Offer on the bridge shifted the hand lever of his instrument from the "ahead" sido
to the "astern side, or rice cerm, he would cause the actuating arm of the bell-crank
to pass it, and in doing so vibrate the bell-crank and lever as it passed and thus ring
the ball to indicate that the engines required to be reversed. The actuating arm on
the reciprocating rod, however, would be so set in relation to the bell-crank, and
to the position of the transmitting hand pointer when in its stopped position, that
it could go on up to “stand by,” “ easy" half," and "full speed" in the forward
orala" direction, without ringing this hell except when the transmitting hand-
pointer was brought back passed the stopped position some distance towards the
astern
indicating sections, to indicate that the reversing of the engines was
desired, when it woukl then suddenly ring this new alarm by causing the arm on the
reciprocating rod to pass the bell-crank, and the actuating arm having passed the
bellerank would again require to be brought back considerably to the other side of
the bell-crank and ring the bell when the orders for going "ahead was again given.
The moving arm would always clear the bell-crank as the orders to "easy," "half,"
and full speed" were given after sounding this bell or alarm for the reversing of
the engines and further give a good free motion of the land pointer near the
stopping position on either side to "stand by" without ringing this alurm or notice
bet. Other equivalent mechanical arrangements might be made for either ringing
a spring-bell or striking a gong or opening the tap or valve of a steam or air whistle
for giving this particular distinctive or new extra alarm from the motion of the
transmitting chains of these indicators, when the engines have to be reversed, or
otherwise it might be for the closing or opening of an electric circuit to actuato an
electric-bell.
"
The same arrangement of mechanism is also equally applicable to steering
telegraphis, on board ship for indicating to the stoersman when the order is
given by the Captain or Officer to roverse the helm from port to starboard or
cice-versa.

Improvements in and relating to Telegraphing Apparatus Used on
Board Ship.
We, WILLIAM FRANCE, and ROBERT MORGAN, both of Whitefield Brass Works,
Govan, Lanarkshire, Brassfounders, do hereby declare the nature of our said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement in writing, reference being had to the
accompanying Sheet of Drawings, and to the letters and figures marked thereon, that
is to say:
This Invention has reference to and comprises the giving of a new and extra
distinctive telegraphic sound or alarm to the Engineer close to his receiving instrument
in the engine room, in 'addition to the ordinary bell or bells in the instrument for
calling attention to each ordinary order when the engines have to be reversed from
"ahead" to "astern" or vice-versa, and for similarly indicating to the helmsman or
steersman when the order is given to reverse from port to starboard or vice versa, and
modes and means of doing so automatically by the action of the instrument used for
giving the usual orders.
And in order that our said invention and the manner of performing or carrying
the same into effect or practice, may be properly understood, we have hereunto
appended an explanatory Sheet of Drawings, in which the same reference letters are
used to indicate corresponding parts in all the figures where shown. Figure 1 is a
front or side elevation of one arrangement of our special sound signalling fittings u to c,
for giving an extra signal only, when the engines or helm or rudder have to be
reversed, as applied to an ordinary dial signalling apparatus A A, with duplex index
pointers A', A, and chains B', B', and mechanism for giving the ordinary orders to
Engineers and Steersmen on board ship and as shown in sectional detail in Figures 2
and 3 to show the action of this apparatus more clearly. Figure 2 is a corresponding
side elevation of a modified form of our improved special sound signalling fittings a
to as applied to the same signalling apparatus, corresponding to Figure I, but with
the dial A A", removed, and bell or gong F, shown in section. And Figure 3 is a
side or edge elevation of the arrangement shown in and at right angles to and
corresponding with Figure 2, with an ordinary signalling apparatus A A shown in
section.
Referring to these Drawings and particularly to Figure 1, these improvements are
applied on board ship to the usual reply or non-reply telegraphic dial instruments
between the Captain or Officer on the bridge, and the receiving instrument in the
engine room shown at A A, and in which the Officer on the bridge turns an outer
handle and index pointer and spindle on his instrument equivalent to A, A', B*, shown
on the receiving instrument, to the pointer A2 and order on the dial he desires
transmitted to the Engineer's receiving instrument A, A, to the right or left for going
ahead" or "astern" in sectional divisions of "stand by,"
"half" and "full
speed" as indicated on the respective sections of the dial at A Figure 1. and vice
"366
easy.

page_text: versa at A on the opposite side of the centre position of the instrument for going
astern, and this motion turns a corresponding central handle A³, on the receiving
instrument in the engine room. The Engineer then in the case of a reply instrument
turns the onter handle and pointer A on his receiving instrument A, A, in like
manner, to the proper section to the right or left of his instrument to give a return
message through the back spindle B and wheel B, and chains B, B2, to the Captain's
instrument on the bridge by a central hand or pointer A2 on the dial of his instrument
to show that he has received the particular messago corresponding to that sent by the
Captain or Officer on the bridge. These instruments have thus two sets of duplex
light chains and rods B1, B2, for transmitting the orders first from the bridge to the
Engineer's instrument A. A, and then back from his instrument to the instrument on
the bridge respectively through double sets of wheels B, and separate spindles B³, B',
with their respective transmitting and receiving hand pointers A², A¹, outside the
dial A" A. In applying our invention or improvements under one arrangement to
this class of in-trnment as shown in Figure 1 of these Drawings, the alarm would
consist of a new or distinguishing alarm hell a in addition to the usual bell or hells F
used for giving a Notice before every order of the ordinary instrument A A, and
secured to a spiral or blade spring at and either mounted at all on a small
portable fixed bracket a² or a stud as in Figures 2 and 3 near the order receiving
instrument AA, with an actuating bell-crank fover connected to it and fuleramed
on a stud at 6" on the said bracket a², having its one arm connected by a light
rigid rod ³, or other equivalent to the spring hanger of, or the bell a, while the other
free tappet end of the bell-crank would he actuated so as to ring the hell a by a
motion in either direction from its normal, proferably horizontal, position as horvin-
after described. The bracket a would also by this arrangement have mounted on it
a reciprocating rode, el passed through guide studs ell or other equivalent at the
opposite ends of the bracket a² with a central projecting arm or tappet e reciprocating
in the plane of the free end of the bell-crank bb, and steadied in this plane or
parallel traversing position by a light rigid wire or rod escured to the said
guides o parallel to the reciprocating rode, so that when this rod e was reciprocated
with its projecting arm e from one side of the free end of the bell-crank to
the other, it would actuate the hellerank and ring the ball a. or this bar e might be
mado square or flat and so work parallel in its guile studs without the necessity for
the parallel guiding wire el. This bracket a³ and its new mechanism would be
mounted close to the receiving instrument A A, in the engine room, with its
reciprocating rode, e, in the straight line of one of the duplex line of chains B¹,
transmitting the orders from the bridge instrument to the receiving instrument in the
engine room, preferably in the vertical direction, and have one line of the chain or
wire B connected by eyes or hooks at ee to the opposite ends of the reciprocating
rode; all so that when the Captain or Officer on the bridge shifted the hand lever A
of his instrument from the "alioad" side to the "astern "side, or vice versa, he would
move the chains B, B1, which turn the front wheel B, and spindle 133, and pointer A³,
and cause the tappet e of the rod e to actuate the arm of the bell-crank bb³, in
passing it, and in doing so vibrate the ball-crank b, and thus ring the bell a to
indicate that the engines required to be reversed. The actuating arm or tappet e' on
the reciprocating rod e however, would ha so set in relation to the holl-crank bb' and
to the position of the transmitting hand pointer A² when in its stopped position, that
it could go on up to "stand by," casy," "half," and "full speed" in the forward or
"ahead "direction, without ringing this bell a except when the transmitting land-
pointer A was brought back past the lowest stopped position some distanco towards
the "astern" indicating suctions, to indicate that the reversing of the ongines was
desired, when it would then suddenly ring this new alarm by causing the arm or
tappet of on the reciprocating rode to pass the arm of tho boll-crank b, b, in the
opposite direction, and the actuating arm c, having passed this arm of the bell-
crank 66¹ in this direction, would again require to be brought back considerably to
the other side of this arm of the bell-crank bb, and stopped position of the hand
pointer A³, and ring the bell a when the order for going "ahead" was nguin givon.

page_text: The moving arm would always clear the arm of the hell-crank 66' as the orders
to " easy," "half," and "full speed" were given after sounding this bell or alarm a
for the reversing of the engines; and further give a good free motion of the hand
pointer A near the stopping position on either side to stand by," or "finished with
engines," without ringing this alarm or notice bell a.
Referring to the modification shown in Figures 2 and 3, the bell a is connected to
an inverted arm of the bell-crank bb' and fulcramed on a pin 61, while instead of
connecting the ends of the chains B' B₁ to a rod c, as in Figure 1, they are carried
round a double grooved pulley c mounted on a fixed stud at on the bracket A²,
and connected respectively to this at c² c³, one of these onds c³ being attached by a
tightening regulating screw ; and the tappet arm c¹ is mounted on the eye of the
wheel a nearly in line with the tappet arm of the shaking bellerank of the
bell a, when the transmitting signal pointer A is near and on either side of its
stopping position shown in Figure 1, of the dial A", A, and acts otherwise all
substantially as described in reference to Figure 1, to give an additional audible
signal by the hell a, only when the engines have to be reversed from ahead to astern
or vice versa. Other equivalent mechanical arrangements might be made for either
ringing a spring-bell or striking a gong or opening the tap or valve of a steam or
air whistle for giving this particular distinctive or new extra alarm from the motion
of the transmitting chains B', B', of these indicators A A, when the engines have to
be reversed; or otherwise it might be by the action and contact of the
points for the closing or opening of an electric circuit to actuate an
electric-bell.
The same arrangement of mechanism is also equally applicable to steering
telegraphs on board ship, for indicating to the steersman when the order is
given by the Captain or Officer to reverse the helm from port to starboard, or
vice versa.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what wo
claim is :-
First. The system, or mode and means, of giving a new and extra distinctive
audible or telegraphic sound or alarm on board ship from the bridge to the Engineer
in addition to the ordinary Notice order bell or bells in the instrument, for indicating
only when the engines have to be reversed from ahead to astern, or vice versa, and
for giving a similar sound or alarm only to the Helmsman when the rudder is to
be reversed from port to starboard, or vice versa, substantially as herein set forth.
Second. The arrangement and combination of fittings indicated by small or italic
letters applied to any ordinary telegraphic signalling apparatus on board ship for giving
a new and extra distinctive audible or telegraphic sound or alarm only when the
engines or rudder respectively have to be reversed, substantially as and in the
manner herein described and distinguished in reference to and shown in
the accompanying Drawings.
