THE AUSTRALIAN SIMPLEX AUTO
By Ron McMullen Former Telegraphist, Telegraph Supervisor, Senior Postal Clerk,
Instructor and Postmaster in the Australian P.M.G. Department.
The Simplex Auto semi automatic Morse code sending machine was invented about 1920 by Leopold Gilbert Cohen, an
Australian Telegraphist. He was the sole manufacturer and distributor until he enlisted in the 2nd A.I.F in late 1939.
The Simplex is what is known as a ‘right angle’ model and inspiration for the Simplex was possibly gained from the Australian
right angled Pendograph and the right angled American Mecograph both of which operated on the ‘tension release’ system
and therefore did not impinge on the patent for the American Vibroplex machine. The Pendograph and Mecograph were
widely used in Australia in the early 1900s before the invention of the Simplex.
In 1923 it was adopted by the Postmaster-General's Department as a standard sending aid for the Commonwealth of
Australia and was also extensively used in Railway Telegraphic Services. The Simplex Auto was issued to Morse operators to
combat ‘Telegraphist’s cramp’ along with other machines such as Vibroplex and even Eddystone.
Unlike such famous names as Vibroplex, there appears to be no recorded history of the inventor or the machine itself.
There were three types of Simplex Auto models – the Standard, semi automatic; De Luxe, fully automatic and a little known
‘in line’, Special, all based on the tension release system. No record of a patent can be found, but ‘The Simplex Auto’ was a
registered Trade Mark. No Simplex bears a patent number.
When Leo enlisted in the army (Australian Imperial Forces) in 1939 it appears that operations covering the Simplex Auto
were taken over by other persons. Advertisements during this period show ‘obtainable from J. W. Layther S.P.C. Carnegie, SE.
9, Victoria. Australian Representative for Leo G. Cohen’.
One Simplex S#6104 is labelled ‘made by Stuart Perrin’. This is the only known machine with this inscription and would have
been after the war period. Perrin was a Telegraphist and Supervisor in Melbourne and is thought to have sold later model
Simplex Autos up to the time of their demise when Morse was faded out.
Leopold Gilbert Cohen was born at Kalgoorlie Western Australia on 11th August 1900. He joined the Australian Post Office at
Healesville, Victoria as a Telegraph Messenger on 18 January 1915 on an annual salary of £39 and later became a Postal
Assistant and Telegraphist in the Melbourne Chief Telegraph Office.
In 1934 he moved to the ‘Postal side’ of the PMG Department as a Senior Postal Clerk (Assistant Postmaster) at Hawthorn,
Vic. and thence in 1937 to Canterbury Vic., again as Senior Postal Clerk, in 1937 before enlisting in the 2nd A.I.F. (Australian
Imperial Force) at South Melbourne on 13th November 1939 with the rank of Lieutenant (on probation), just two months
after the outbreak of the Second World War.
He was assigned to a Postal Unit with the 6th Division departing for overseas on 9.1.40 and saw service in the Middle East
until disembarking in Sydney on 28.2.43. He was promoted to Captain on 28.10.41.
He then served in Northern Australia, being promoted to Major on 19.11.43 and served in New Guinea from 27.2.45. to
13.8.45. He was in charge of Army Postal Services in the Northern Australia region. On 29 August 1945 he returned to New
South Wales and later to Victoria where he was discharged from the Army on 30.1.46.
He returned to the Post Office after the war being Postmaster at Warracknabeal (this may have been a nominal designation,
not requiring him to actually take up duty at that office), Burwood and Armadale (all in Victoria). He died after retirement, at
Camberwell, Vic. on 30 March 1954.
1st Model:
The first Simplex Auto model is easily distinguished by the single
finger/thumb paddle. Later versions carried the separate finger and
thumb pieces. It had a black painted base with a small brass label
reading ‘SIMPLEX AUTO ### L. G. COHEN MELB’ placed under the post
carrying the dot travel screw. There were four posts along the front.
There were separate posts for the dot travel arm and the dot tension
spring. The bridge carried only the pivot adjusting screw and a semi
circular cut out at the right hand end to provide access to the dash
tension spring. One lead of the cord was attached to the top of the
base by a single screw rather too close to the ‘U’ shaped frame carrying
the dash tension screw. The other lead of the cord was attached to a smaller dash post than that of the second model. The
vibrator arm was round with the damper post located at the rear center of the base. Fittings were all nickel plated. The
under base current connection was via a brass strip between the dash and dot contact posts.
2nd Model:
The second model had four posts located on the front of the black
painted base and carried a label on the bridge with the name ‘Simplex
Auto’ sloping upwards from left to right and ‘Leo G. Cohen Telegraphist
C.E.T.O. Melbourne’. (C.E.T.O. Melbourne being the initials of the Chief
Electric Telegraph Office). This may have been about 1923 when the
Simplex was adopted by the P.M.G. Department. The bridge carried the
semi circular cut out. The round finger/thumb piece of the first model
was replaced by separate finger/thumb pieces and the lead for the cord
placed on a terminal post positioned further to the back of the base.
The dash contact post was also enlarged. The damper post remained at
the rear center of the base. The vibrator arm was round with one side
flat. Not more than about 400 had 4 posts; all later models had only 3
with the combination of the dot travel arm and dot tension spring.
Some had all brass fittings. Early models had the damper post located at
the centre back of the base and the damper screw had an insulated
inset at its end or alternately an insulation stop on the dot travel arm screw. Later models with the damper located at the
rear left end of the base had a plain screw, but the end of the vibrator arm was threaded and covered by an insulated sleeve.
3rd Model:
The third model had a black painted base and three posts located on the front of the base. This model saw the amalgamation
of the dot travel arm screw and the dot tension spring on the one post. It is identical to the second model in all other
respects.
4th Model:
The fourth model saw the dash adjustment spring relocated to the
position formerly occupied by the fourth post although not on the base.
A right angled piece attached to the arm carried the dash tension spring
and screw. This resulted in a straight line of the bridge with no need for
the ‘cut out’. There was also a change in the label with ‘Simplex Auto’ in
large lettering at each end, curving inwards top and bottom to smaller
letters at the centre. C.T.O.. (with two dots) replaced C.E.T.O. reflecting
the fact that the word 'electric' was dropped from the Telegraph Office
title which may have been about 1925. The actual size of the label was
slightly larger than previously to accommodate the extra wording
‘manufactured by’ above Cohen’s name and ‘Vic.’ after Melbourne. The
vibrator arm was square. This model was available with plated base or
black painted base.
5th Model:
The fifth model had changed wording on the label. The words
‘Telegraphist C.T.O.’ were dropped, perhaps indicating that Cohen had left
the C.T.O. and moved to the Post Office side of the PMG Department
(1934). The vibrating arm was round with one flat side. The flat circuit
connection under the base was replaced by a round cable.
6th Model:
The sixth model was called the ‘De Luxe’ being fully automatic; automatic
dots and automatic dashes. They were quite a complex machine. These
are easily distinguished by the ‘in line’ appearance, large top plate and the
three paddles. Comparatively few were made, possibly because they had
to compete with the ‘Automorse’ which had by that time become
established and the fact that they required a further ‘learning curve’ and
any advantage over using a semi automatic was not great. They are rarer
than the Automorse. From this time, the semi automatic Simplex became
known as the Standard model. The ‘De Luxe’ was the only Simplex to carry
a circuit closer. If made, the ‘Special’ model may have. Early examples of
this model (only 3 known to date) had nickel plated bases.
7th Model:
The seventh model had a fully round vibrator arm with the damper post
relocated to the left hand rear end of the base.
8th Model:
The eighth model saw the replacement of the square dash post with a
round post and the deletion of the two terminal screws carrying the
connecting cord and plug. One screw was provided beneath the base for
one cord terminal with the other connected underneath the dash post.
Some machines around this period were furnished with a long flat dot
spring with a ‘hook’ at the contact end.
9th Model:
The ninth model indicates two changes. The under base screw for one cord
terminal provided only on the eighth model was deleted and that cord
terminal placed on the bridge screw. The pivot adjusting screw previously
located on the right hand end of the bridge was relocated beneath the base.
This arrangement continued for all future models. Some left hand models of
this type were made and perhaps of other models also. This was also the
commencement of the black wrinkle painted bases and the sloping sides of
the bridge.
Generally models up to this period, with the exception of the two ‘cut out’
models had nickel plated bases.
10th Model:
One remaining model bears no label at all and no holes in the bridge for
fixing points. These were made for the Australian defence forces during
World War 2 and the components appear to be of a poorer quality than
previously. Some of these reverted to the PMG Department and possibly
others such as Civil Aviation for issue to operators. Mine is stamped
C of A 45 which was typical Commonwealth of Australia identification.
Left Hand Model:
Various models were made in left hand versions. Possibly they were made
as special orders when required.
11th Model:
The eleventh model saw a significant alteration to the wording of the label.
Cohen’s name was dropped, with the wording being simply ‘Melbourne
Victoria’. However there is, as always, an exception. At least one of this
model in the early 6xxx series bore the nameplate ‘The Simplex Auto (Regd)
made by Stuart Perrin’. Perrin was a Supervisor in the Melbourne C.T.O. This
possibly indicates the exit of Cohen from the business. Who manufactured
later models is not known. Some bases in this model were 6¼" long instead
of the usual 6".
Special Model:
About 1938 a nickel plated semi automatic ‘Special Model’ Simplex priced
at £2/5- was advertised along with the ‘Standard Model’ priced at £3/7/6. A
later advertisement priced the ‘Special’ at £2/10/- being ‘obtainable from J.
W. Layther S.P.C. Carnegie S1 9 Victoria Australian Representative for Leo G.
Cohen’. This would indicate that it was later than November 1939, when
Leo enlisted in the A.I.F. None of this model is known to exist and it seems
likely that none or very few were actually manufactured and sold. The
‘Special’ bore a resemblance to the ‘De Luxe’, being an ‘in line’ model and
having a large rectangular top plate supported on four posts. The ‘De Luxe’
model was advertised as ‘again available at £5/5/-’
The same advertisement stated ‘All Simplex Autos are guaranteed by the maker for ever against wear and accidental
damage. Simply return the broken parts and pay postage both ways. No other charges whatsoever’.
Mystery Jigger:
A completely new version of the Simplex Auto has just come to light (March 2014). It is an ‘in line’ wooden base model with a
No. 3 label, 1067 attached. This indicates that it followed the C.T.O. or 4th model. It has some of the C.T.O. parts – terminal
screws, thumbscrew, thumbnut, various posts and oddly the same paddle as used in the very first model. The triangular top
pivot plate has a ‘Vibroplex’ Look. The vibrator is square rod with a square holed weight. The damper at left back is also
simple and unique. Other parts are common screw types or plain brass. It seems to have an over long main arm.
This leads me to believe that it may have been a prototype for the ‘Special’ model. As such it would have been quite
reasonable to use a mismatch of parts.
It was obtained from a 90 year old gentleman in suburban Melbourne who said it had been in his shed since the 1930s and
previously belonged to his father.
It has been professionally made and quite a good key to use.
This is another mystery jigger – Is it a Simplex Auto?
Another mystery has appeared in September 2014. It has many Simplex Auto characteristics and could be an unknown
version or a similarity. Black painted metal base 115 x 75mm similar to 2nd model, but hole for the bridge has never been
drilled right through so a bridge could never have been fitted. All nickel plated fittings. Round vibrator arm with one flat side.
Damper centre rear. Straight main arm with no joint. Black plastic thumb piece stamped RADIO. Black plastic finger piece
which is not typical Simplex Auto type. Upright Z shaped post to carry pivot screw. Knurling pattern is thick and sloping – not
typical of Simplex Auto. No label.
Oddities:
At least two machines, 6594 and 6601 have bases 6¼" x 3" x ½" as opposed to the usual 6" x 3" x ½".
618 has all the parts of a Model 4 machine, but has the Model 3 plate.
3032 is a Model 3 C.T.O. This number is out of sequence and should apply to the next model. Perhaps an old label used very
shortly after change to new model.
Some machines in the 6000 series used three very thin metal strips in lieu of a single strip for the long flat dot spring. These
appear to have been subject to failure of one or more of the strips and few have been seen.
Leaflets:
Each new Simplex was issued with an instruction leaflet of 4 pages. There were three separate designs, but in the absence of
any dates on these it is not possible to say when the change to the new version occurred. One machine bought new in
January 1939 had the second style leaflet. The third style is obviously after 1939 as it shows Leo as A.I.F.

Second leaflet:
Third (Wartime) Leaflet:
These were printed on cream paper with brown printing and on smaller sized paper.
Advertisements:
Only two advertisements have been found and both with almost identical wording. The first one shown here was advertised
in ‘The Australian Telegraphist’ of 20 February 1945, the period when Leo Cohen was on war service. The second
advertisement would have been from a similar period. Note J. W. Layther’s address has changed.
It is a pity that little is known of the history of the Simplex Auto or its inventor. I have endeavoured to piece together some of
it by reference to the Australian Archives for Cohen's war service record and from machines in my own collection as well as
290 serial numbers and details provided by many others to whom I am grateful. There have been some minor changes to
various parts of the Standard machine, but the overall design has remained largely unaltered.
There has been a theory that serial numbers commenced at 101. The earliest known number is 120 and the latest 7335.
All serial numbers were punched, apparently by hand, as evidenced by the uneven spacing and uneven alignment of the
individual numbers. Leo may never have envisaged making even a thousand and by starting numbers at 101 avoided any
confusion in numbers which may have been caused by others adding more digits at either end of his original serial number.
Of about 335 recorded numbers there are only three (1003, unconfirmed; 1010, photo held and 1067, actual machine held)
in the 1000 series and none in the 2000 series. Perhaps, as sales increased Leo commenced renumbering at 3001 – one of
the mysteries of the Simplex.
I have used the term ‘model’ purely to indicate the various changes which have occurred from beginning to end. To every
Australian Morse operator any Simplex was simply and affectionately known as a ‘jigger’. Their standard of manufacture and
operation was equal to the best in the world. New information is gradually coming to hand and any further would be
appreciated.
Serial Numbers:
Serial numbers appeared on labels and below are samples of the various types of labels.

2.
4.
3.
5.
In the absence of any confirmed history of the Simplex Auto, I am assuming:
1.
From about 1920 when the Simplex was invented Type 1 label was used. Before adoption by the P.M.G. Dept.
2.
In 1923 the Simplex Auto was adopted by the P.M.G. Department. It may have been from that time that Type 2
label (‘Telegraphist C.E.T.O.’) was used.
3.
About 1925/26 a wide ranging reorganisation of the Department was made and it is possible that the ‘E’ (Electric)
was dropped from the title of the Chief Telegraph Office and Type 3 label was used.
4.
Leo Cohen left the Telegraph Branch and moved to the Post Offices Branch in 1934 and this was probably the reason
for ‘Telegraphist C.T.O.’ being dropped and the Type 4 label used. It is possible Type 3 labels cold have been used for
a short time after.
5.
Between November 1939 and January 1946 Leo Cohen was on Military service and J. W. Layther acted as an agent
for the sale of Simplex Autos and Type 4 labels were used.
6.
Leo Cohen died in 1954 and it is unknown who produced the Simplex Auto from that time. This probably resulted in
all reference to Cohen being dropped in Type 5 labels.
7.
Simplex Autos without labels were made for the Military during World War 2 and are often found with non matching
parts.
Following is a list of serial numbers and some details of each. My sincere thanks to those who have provided these.
