IMPROVEMENTS IN TELEGRAPHIC TRANSLATORS
Year: 1884

page_text: I, WILLIAM, EDWARD GEDGE, of N° 11 Wellington Street, Strand, London in the
County of Middlesex, Patent Agent do hereby declare the nature of my invention
for "IMPROVEMENTS IN TELEGRAPHIC TRANSLATORS" to be as follows:-.

This Invention relates to a new arrangement in a telegraphic. line with t
Morse relays by means, of which a working current may be converted into a
continuous or permanent one and vice-versa.
To permit such a conversion with two Morse relays it is necessary. to give the
two relays an arrangement other than that which would be sufficient for a simple
translation of a working current.
:
.
The accompanying drawing shows this modified arrangement on the two relays.
I use a relay R similar to that described in my Specification No 8990 AD 1884,
excepting that the hook k is below instead of above the anchor.lever.
The anchor-lever of the relay R2 introduced into the circuit of the continuous or
permanent current has been modified as follows:
On the anchor-lever, to the right of the wire, bobbins is fixed a small metallic
piece m separated from the lever by an insulating layer e.. This metallic piece has
for its purpose to receive the current departing for the circuit N, which enters over
the contact after the falling off of the anchor, and to conduct it directly over g₁
and h¹ to the circuit N, without passing through the relay R¹.
Behind the anchor-lever, to the right of the posterior wire-bobbins is a guiding-
piece. h¹ fixed on the relay but insulated from it, which, takes up one extremity of
the wire-spiral g¹, the other extremity of g¹ being fixed on the metallic piece m by
means of the binding screw 8. The construction of the wire-spiral g₁ is the same
as that of g; the spiral g¹ has consequently no essential influence on the movements
of the anchor..
The Key-lever T, is provided with a broken working contact-plater and ™ª¹³, as
shown in the drawing. The smaller part at the left is combined with the contact d¹
of the relay. R², on the longer part at the right is the working contact and further
a battery-plate v..

B', is the battery of the working current.
B2, the battery of. the continuous or permanent current, OW, the circuit of the
continuous or permanent current, N, the circuit of the working current.
In order to translate a despatch from the circuit of the continuous or permanent
current OW, to the circuit of the working current N, or vice versa, it is necessary
to stop up the holes 1 at U¹ U³ Û³ and T by the conducting plugs.
The path of the current in the circuit of the continuous or permanent current
from O to W, is as follows:-
O, G², S, B², U2, R2, R¹, (h gik.C, C), U2, (hole 1) T2, W, so that the anchor-
levers are attached at.S and R2 and lying on the rest contacts.
The path of the current in the circuit of the working current is as follows:-
N, G, T, U, (over hole 1) R¹ U (middle plate) n n¹d U³, (front plate) to the
ground.
If the chief current in the circuit OW, is interrupted by pressing down
the key, S2, and R³, become inefficacious, the anchor-lever n' falls down at R², so
that the communication with the ground is interrupted at d, and leans with the
metallic piece m against the contact d¹.
The working current, of the battery B¹ being closed takes its way over (the
battery is with one pole in communication with the ground) B₁ T¹, (hole 1) R³
(contact m g¹ h¹) U³, (hole 1) U', (hole 1) T¹ (rest-contact-plate, body of the key
lever) G to the circuit N, and puts the indicator of the distant station in motion.
This current cannot take its way from the commutator U₁ over R, U (middle
plate) the anchor-lever n, n' to d and to the ground, because the anchor-lever n, n¹
is lying against the contact das long as there is a departing current circulating in
the circuit; the communication with the earth is consequently interrupted.
The anchor-lever C, C¹, is therefore lying on the rest-contact and keeps the
circuit OW, closed at k.
'
If the distant station of the circuit N sends a current into the circuit which
finds its way over n, n', d, to the ground, the anchor-lever of the relay R¹, is
attracted and the steel-spring i laid on the contact 1, so that the local curront
'('B', U'R³, h, g, i) of the relay R' is closed.
The lever is then lifted off at k in consequence of the pressure and therefore the
'continuous or permanent current OW, interrupted.
The anchor-lever of the relay R² remaining on the rest-contact, a disturbing
current cannot enter into the circuit N, the local current (i) being closed before
the current OW, is interrupted, the communication with the ground is always
maintained at d.
.
If the current ceases in the circuit N, the anchor-lever C, C¹ falls off. The steel
spring i rests on the contact until it has reached the shoulder k and closes here
the circuit OW then only it leaves the contact A, so that the local current (l' ¿) is
open.
An uninterrupted current passes through the wire-bobbins of the relay R
during the whole time one is working in the circuit N, because the closing of the
local current is always anterior to the opening of the main current, and the closing
of the main current anterior to the opening of the local. current; the anchor
lever n; n is consequently always attracted and rests on the contact-d, by-means of
which on one side the communication with the ground is maintained, and on the
other no disturbing current may enter into the circuit N. The relays may be

page_text: supplied by indicators provided with the above described arrangements so that the
latter are fit not only for writing but also for translating.
The
The system of transmission with the circuit N, is separated from the circuit OW:
At the commutators U³ and U³, the conducting plug is taken out of the hole 1
and put into the hole, 2. The current of the circuit of the continuous or permanent
current OW, 'takes its way now over 'O, G', S', B', U', (hole 2) T2, W etc.
anchor-lever of the relay R2 falls off because this end is now without current; a
constant current would enter into the circuit N unless at U³ the plug had been
taken out of the hole 1 and put into the hole 2 by which means the circuit is
broken at U³ for the departing current; the arriving, current of the circuit N, on
the contrary, the communication of which with the ground is equally interrupted
at d, passes at U³ through the plug of the hole 2 over the front plate to the
ground.
When a station of the circuit N, calls, the relay R¹ is put in motion and the
local (, ) current is so closed. The relay R³, is also put in motion, and in this
case as an apparatus intercalated into the working current.
It is now possible to hear when stations of the circuit N, are calling stations of
the circuit O W, and to establish then the communications between the two
circuits, so that the stations may reach one another.
The circuit N, is put in communication with the indicator S¹, in putting out of
circuit the two relays R' and R. Should it be necessary for one reason or
another to separate the circuit N, of the continuous or permanent current.O W,
from the system of transmission, the conducting plug at the commutator U!, and
the key T, may be taken out of the hole 1 and put into the hole 2.
The system of transmission and the circuit OW, are now put out of circuit and
the indicator S', is put into circuit.
The path of the current of the circuit N is now as follows N, GU¹ (hole 2) S¹,
and to the ground. When the key T¹, is pressed down, the departing current passes
over B, T, (hole 2) G¹ to N, etc.
The circuit N, has become in this case an independent one.

I, WILLIAM EDWARD GEDGE, of No 11 Wellington Street Strand, London, in
the County of Middlesex Patent Agent; do hereby declare the nature of my
invention for "IMPROVEMENTS IN TELEGRAPHIC TRANSLATORS and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
This Invention relates to a new arrangement in a Telegraphic line with two
Morse relays by means of which a working current may be converted into &
continuous or permanent one and vice-versa.
To permit such a conversion with two Morse relays it is necessary to give the
two relays an arrangement other than that which would be sufficient for a simple
translation of a working current.
The accompanying Drawing shows this modified arrangement on the two relays.
I use a relay R₁ similar to that described in my Specification No 8990. A D 1884
excepting that the hook k is below instead of above the anchor-lever.
The anchor lever of the relay R2 introduced into the circuit of the continuous or
permanent current has been modified as follows:-
On the anchor-lever, to the right of the wire-bobbins is fixed a small metallic
piece m separated from the lever by an insulating layer e. This metallic piece has
for its purpose to receive the current departing for the circuit N, which enters
over the contact d¹ after the falling off of the anchor, and to conduct it directly
over gland, h¹ to the circuit N, without passing through the relay R¹.
Behind the anchor-lever to the right of the posterior wire bobbins is a guiding
piece fixed on the relay but insulated from it, which takes up one extremity of
the wire-spiral g¹, the other extremity of g'.being fixed on the metallic piece m by
means of the binding screw s.
The construction of the wire spiral g₁ is the same as that of g; the spiral g¹ has
consequently no essential influence on the movements of the anchor.
The key-lever T¹ is provided with a broken working contact-plate
shown in the Drawing.

The path of the current in the circuit of the continuous or permanent current
from O to W, is as follows:-0, G³, S, B³ U' R², R¹ (h gik C' C) U, (hole 1)
T, W, so that the anchor levers are attached at S₁ and R' and lying on the rest
contacts.
The path of the current in the circuit of the working current is as follows:
NG TU (over hole 1) R¹ U³ (middle plate) n n¹ d U³ (front plate) to the
ground.
;
If the chief current in the circuit O W, is interrupted by pressing down the
key S and R', become inefficaious, the anchor-lever n' falls down at R³, so that the
communication with the ground is interrupted at d and leans with the metallic
piece m against the contact d'.
The working current of the battery B¹ being closed takes its way over (the
battery is with one pole in communication with the ground) B' T¹ (hole 1) R2
(contact d' mg h¹) U³ (hole 1) U' (hole 1) T¹ (rest contact plate, body of the key
lever) G¹ to the circuit N and puts the indicator of the distant station in motion.
This current cannot take its way from the commutator U₁ over R, U³ (middle
plate) the anchor-lever n n¹ to d and to the ground, because the anchor-lever n, n¹
is lying against the contact d¹ as long as there is a departing current circulating in
the circuit; the communication with the earth is consequently interrupted.
The anchor-lever C C' is therefore lying on the rest contact and keeps the
circuit O W closed at k
こ
If the distant station of the circuit N sends a current into the circuit which
finds its way over n n' d to the ground, the anchor-lever of the relay R' is
attracted and the steel-spring i laid on the contact l, so that the local current
(B, U, R², h, g, i) of the relay R' is closed.
The lever is then lifted off at k in consequence of the pressure and therefore the
continuous or permanent current O W, interrupted.
The anchor-lever of the relay R2 remaining on the rest-contact, a disturbing
current cannot enter into the circuit N, the local current (li) being closed before
the current OW is interrupted, the communication with the ground is always
maintained at d.
If the current ceases in the circuit N, the anchor-lever C C' falls off.
The steel spring í rests on the contact ¹ until it has reached the shoulder k. and
closes here the circuit O W then it only leaves the contact. 7, so that the local
current (i) is open.

An uninterrupted current passes through the wire-bobbins of the relay R
during the whole time one is working in the circuit N, because the closing of the
local current is always anterior to the opening of the main current, and the closing
of the main current anterior to the opening of the local current; the anchor
lever n n¹ is consequently always attracted and rests on the contact d, by means of
which on one side the communication with the ground is maintained, and on the
other no disturbing current may enter into the circuit N.

The relays may be supplied by indicators provided with the above described
arrangements so that the latter are fit not only for writing but also for translating.
The system of transmission with the circuit N, is separated from the circuit O W.
At the commutators U and U³ the conducting plug is taken out of the hole 1
and put into the hole 2.
The current.of the circuit of the continuous or permanent current O W takes its
way now over O G³, S³ B² U² (hole 2) T, W etc. The anchor-lever of the relay R
falls off because this end is now without current; a constant current-would-enter
into the circuit N unless at U the plug had been taken out of the hole 1 and put
into the hole 2 by which means the circuit is broken at U³ for the departing
current, the arriving current of the circuit N, on the contrary the communication of
which with the ground is equally interrupted at d, passes at U³ through the plug
of the hole 2 over the front plate to the ground.
When a station of the circuit N calls, the relay R₁ is put in motion and the
local (i) current is so closed.

page_text: The relay R², is also put in motion, and in this case as an apparatus intercalated
into the working current..
It is now. possible to hear, when stations of the circuit N, are calling stations of
the circuit OW and to establish then the communications between the two circuits
so that the stations may reach one another. :
The circuit N, is put in communication with the indicator S¹, in, putting out of
circuit the two relays R' and R'. Should it be necessary for one reason or another
to separate the circuit N of the continuous or permanent current .O W, from the
system of transmission the conducting plug at the commutator U, and the key.T),
may be taken out of the hole 1 and put into the hole 2..
The system of transmission and the circuit O W, are now put out of circuit and
the indicator S¹, is put into circuit..
The path of the current of the circuit N is now as follows N G₁ U¹ (hole 2) S¹,
and to the ground. When the key T, is pressed down, the departing current
passes over B T (hole 2) G¹ to N, etc.
.
The circuit N, has become in this case an independent one.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
:
The above described arrangement on two Morse relays, by which, it will be
possible to establish at any point and parallel with a primary circuit a secondary
circuit with only one wire, which works with the primary circuit as well as the
priinary, circuit works itself. The arrangement consists principally, in the
combination of the following parts:
a-on the relay R¹.
1. The head piece a fixed on the anchor-lever C C¹ which is prominent down-
wards over the lever and regularly bent inwards to a hook and provided on its
extremity with a little shoulder, or in the place of it with a little metallic
regulating screw, for the purpose of limiting the stroke of the steel spring i and of
conducting at the same time the electric current arriving from O over i to C¹. C-W
and to cause jointly with the steel-spring the opening and closing of the main
current O W.
2. The movable steel-spring fixed on the under side of the anchor-lever C C¹
and insulated from it.. In its position of rest the spring i lying on the shoulder K
of the hook, forms here a contact and closes the circuit O W.
b on the relay R³.
The metallic piece m fixed on the upper side of the anchor lever n n¹ and
insulated from the lever, for the purpose of taking up the current entering over the
contact N and departing for the circuit N, and to conduct it, directly over g¹¹ to
the circuit N without passing through the relay R.
The combination of the apparatus above described and shown in the Drawings
by means of which :-
1 The local current (i) is closed and the main current (i, k) opened by the
relay R and vice-versa.
2 A double circuit is established by the relay R³, so that one the current
departing for N is sent into the circuit N, without passing through the relay R¹
and on the other side the current arriving from N is conducted through the
relay 'R' and over the anchor-lever n n¹ and contact d to the ground.
