PEEL CONNER TELEPHONE PARTS
Electro-Magnetic Receiver (Used in CB sets)
The construction of our Receiver will clearly demonstrate that we have
prominently considered indestructibility and freedom from adjustment troubles,
as well as high efficiency ; the two former points are of no small consideration
to Telephone Companies, as up-keep cost in their direction assumes a large
proportion of the Maintenance Account.
The outer Case of the Receiver is made of solid-drawn sheet Brass in one
piece, and is finished with a coat of special stove enamel which will withstand
the roughest ordinary usage. This is absolutely unbreakable. The general
appearance will be seen from Fig. 112.
|Fig. 112 ELECTRO-MAGNETIC RECEIVER, dismantled
Code No. C103 - Approximate Weight, 13ozs
The Magnetic Circuit is composed chiefly of a special malleable iron selected
for its magnetic qualities, the core being of the finest Swedish iron wire
properly annealed. Great care has been taken to grind the pole piece to the
exact dimensions required to establish a permanent adjustment from the
Diaphragm, and at the same time assure the highest efficiency; the Coil is
designed to take the maximum number of turns in the smallest space, the winding
being special enamel-covered wire.
The Terminals, to which the Cord is attached, are securely fixed and
completely insulated from the frame by means of best quality Ebonite, and an
insulating washer is provided between the working parts of the Receiver and the
outside case, which prevents the possibility of shock to the user, should the
winding become connected with the Frame.
The use of this Receiver eliminates a fault common to the very best type of
permanent-magnet Receivers, namely, the permanent bowing of the Diaphragm; this
is due to the constant pull of the permanent magnets, which in time causes the
Diaphragm to touch the pole pieces, thereby rendering the Receiver practically
useless until the Diaphragm has been replaced by a perfectly flat one. In our
Electro-Magnetic Receiver, the Diaphragm has no magnetic pull exerted against
it, excepting when in actual use, consequently it has plenty of time to recover
its normal flat condition.
All adjustments are permanent on leaving the Factory.
Electro-Magnetic Receiver with Ebonised Finish to Case
To suit the requirements of those who specify an ebonised coating to the
Receiver Case, we have arranged to stock our C103 Receiver (described above)
with this finish. When ordering this type, please be careful to give Code number
Code No. C103K.
Approximate Weight, 13ozs.
Bi-Polar Receiver (Used in Magneto Sets)
The Receiver plays an important feature in daily telephone service, and is
frequently a nuisance to the Subscriber through getting out of adjustment, and a
considerable item of expense to Telephone purchasers, due to broken cases. The
Peel-Conner Receiver has neither of these drawbacks, and a perusal of the
under-written description will show that we present the finest and most
economical Receiver on the Market at the present time.
|Fig. 47 BI-POLAR BELL RECEIVER, with Cord
in Unbreakable Solid-drawn Shell
||All Sets except Tropical
Approximate Weight, 14-oz.
The Case or Shell is made of solid-drawn sheet Brass in one piece and is
absolutely unbreakable, a point which will at once appeal to Telephone Companies
who desire to see their " Broken Receiver Case Account " disappear. This Case or
Shell is coated with a tough black insulating enamel stoved on, which will
neither chip nor flake under the roughest usage. The Pole Pieces are ground to
exactly the proper depth - as they are not intended to be adjustable - and great
care is taken to ensure that the surfaces clamping the Diaphragms are perfectly
uniform to avoid distortion or buckling, as it is necessary to permanently
maintain the air gap within one thousandth part of an inch of its established
dimensions. The Receiver Magnet is of the horse-shoe type made of the best
quality Magnet Steel, scientifically hardened and magnetised.
|Fig. 48 BI-POLAR BELL RECEIVER, dismantled
The working parts are contained in a brass cup, the spools being provided
with Brass Cheeks and wound with high conductivity silk-covered copper wire to a
uniform resistance. The Metal Shell is threaded on one end to take the Ear Cap
and all our Telephones - unless otherwise specified - are fitted with this
latter, moulded from a special jet black composition, highly polished, which
closely resembles best quality ebonite ; for ordinary service we strongly
recommend it, as it is just as durable and less expensive.
We would emphasise the fact that all working parts of the Receiver are
entirely insulated from and independent of the Case, which precludes possibility
of shocks, and also renders it impossible for variation in temperature to have
any effect upon the permanent adjustment of the Receiver itself.
Watch Receivers (Used in Magneto Sets)
Figures 49 and 50 illustrate the Peel-Conner Watch Receiver, which, from
point of simple design and high efficiency is an ideal piece of apparatus when a
second Receiver is found desirable.
|Fig. 49 BI-POLAR WATCH RECEIVER
In Solid-drawn Aluminium Shell
The Shell is absolutely unbreakable, being made of solid-drawn Aluminium with
highly polished finish; the Magnets are of the ring type, made of the finest
Magnet steel scientifically hardened and magnetised, and the pole pieces are
carefully ground to exactly the proper depth - as described above for the
standard Receiver - thus ensuring permanent adjustment.
||All Sets except Tropical
Approximate Weight, 6-oz.
The whole of the working parts are contained in a brass cup, and are entirely
independent of the Case or Shell, which eliminates the possibility of shocks,
and also prevents variations in temperature taking any effect upon the permanent
adjustment of the Receiver itself.
|Fig, 50 BI-POLAR WATCH RECEIVER
This is our standard Transmitter as fitted on all Peel-Conner Central Battery
Telephones. It is of the solid back type, having the Electrodes and Carbon
granules enclosed in a hermetically sealed capsule which prevents the
Transmitter deteriorating by reason of climatic conditions or changes. The front
and bridge are of heavy sheet brass, and the carbon Electrodes are extremely
hard with highly-polished surfaces. Specially selected carbon is used for the
granules, and as this is entirely free from dust, the danger of "packing" is
eliminated. No part of the front or case forms part of the electrical circuit.

Code No. C1000 - Approximate Weight, 11oz
Taking orders received as the best criterion of excellence, we confidently
assert that this Transmitter cannot be surpassed.
Transmitter Arm for Standard Wall Set
This consists of two parts, viz. the Base and Arm, which are made of pressed
Steel, finished with black enamel; a heavily plated machine bolt connects the
two together, and, when so combined, the arm itself is adjustable, moving freely
through a sufficient radius to accommodate the varying stature of the users. Its
hollow construction provides perfect protection for the two Transmitter Cords
carried inside, and particular attention is drawn to the fact that neither the
Arm nor Base form part of the Circuit, therefore it is impossible to sustain a
shock by coming in contact with either these or the Transmitter.
|Fig. 114 TRANSMITTER ARM
Code No. C 102 -
Approximate Weight, 8ozs
The fixing of the Arm to the Backboard is effected by four substantial screws,
which constitutes a feature of advantage in case of shipment, as it permits the
Transmitter Arm to be packed separately, thus protecting it from damage in
course of transit, while the fixing of same to the Backboard is but the work of
a few moments.
Transmitter Arm for Residence Wall Sets
This Arm has been specially designed for those who prefer an adjustable
Transmitter to one in a fixed position. It is quite self-contained and strongly
constructed of pressed steel, highly finished; a substantial machine bolt, with
lock nut, forms the connection between the base and arm, while the Transmitter
cord is protected against damage by being laid in a machined slot in the
Transmitter case mounting.
TRANSMITTER ARM FOR RESIDENCE WALL SETS
Code No. 103 -
Approximate Weight, 6ozs
The complete Arm, with Transmitter fitted, is illustrated in Fig. 115, and we
recommend this simple, but strong piece of apparatus, to those who wish their.
Telephone to accommodate itself to users of varying stature.
Figs. 116 and 116A illustrate our standard Hook Switch with removable Lever
Hook, which can be readily attached to the Set when closed, but cannot be
withdrawn unless the Cabinet is opened. The Switch Springs are made of
hard-rolled German Silver, and are mounted on a pressed steel frame, heavily
zinc coated, to which is also attached the Hook Escutcheon Plate. It will be
observed that the Switch, as a whole, is self-contained, and is far superior to
one comprising separately-mounted parts, as it does not become liable to the
latter's errors of adjustment.

Induction Coils (Used in Magneto Sets)
The Induction Coil forms a necessary item of the local battery telephone,
its most important function being to step-up the low-pressure primary currents
furnished by the two cells of a battery to such a magnitude as to enable them to
easily penetrate the resistance and retardation of the line circuit.
Fig. 51 is an illustration of our No. C102 Induction Coil which is fitted on
all our magneto sets, and shows the method in which the ends of the Coil are
terminated. The windings are proportioned to give the highest possible
transmission efficiency and uniform results. The Core consists of a bundle of
soft Swedish Iron Wire carefully annealed, giving a minimum hysteresis loss. The
Spool is turned out of solid hard wood treated with a preservative black
varnish, and wound with high conductivity silk-covered copper wire, the ends
being brought out with braided heavy gauge flexible conductors soldered to
copper tags. This method of terminating the windings gives great flexibility,
and removes possible trouble on account of broken ends.
The outside of the Coil is covered with bookbinder's cloth to protect the
wire from mechanical injury. A hole is drilled through each of the heads, so
that the Coil can be securely fastened to the Cabinet by means of round head
wood screws. The primary and secondary windings are distinguished by the letters
"P" and "S" stamped on the cheeks of the coil. When required for tropical use
the windings are of enamel insulation.

Lightning Arrestor (Used in Magneto Sets)
Fig. 52 represents our No. C101 Lightning Arrester, which is fitted to all
Peel-Conner Magneto Sets, with the exception of the "Strongphone"; this type is
well known in the Telephone field. It consists of two metal discs insulated from
each other and securely clamped to an Earth Plate but separated there from by
thin perforated mica distance washers. To these Metal Discs the line wires are
terminated. The surface of the Discs is of sufficient area to warrant a good
discharge, and the arcing distance between them and the Earthing Plate is
accurately determined by the mica Washers being of a standard thickness ;
consequently no adjustment is required after it leaves the factory. The mica can
be easily renewed, if necessary, by removing the milled nuts, and a great
advantage of this type of Lightning Arrester is that faults caused by carbon
dust are entirely eliminated.

Generators (Used in Magneto Sets)
On this and the following page we illustrate our standard 3, 4, and 5-Magnet
Generators. These Generators are of high-grade manufacture, and the materials
used in their construction are the very best obtainable; they are, moreover,
designed with a view of giving maximum efficiency for the service for which they
|Fig. 53 3-MAGNET GENERATOR
Code No. C103
Approximate Weight, 4-lbs. 13-oz.
The Generator armature revolves in a very powerful field, and the winding of
silk insulated high conductivity copper wire is of such resistance, as to give a
sufficient amperage for ringing the maximum number of bridged bells with a
minimum drop in voltage. The armature is of the single-coil type, the core of
the 4 and 5-Magnet Types being built up of highly permeable annealed iron
laminations assembled on a steel spindle and accurately machined. The gearing is
of solid cast brass, machine cut, and capable of hard wear, the engaging metal
surfaces being amply proportioned. The end plates which hold the assembled
generator together are of solid cast brass, with armature and crankshaft
bearings cast in. The bearings are of sufficient length to give good wearing
surface, and being cast solid always maintain a perfect alignment which ensures
smooth running; lubrication is provided for by machined oil ducts in the end
plates. The pole pieces forming the field are of annealed soft iron, heavily
electro-plated with zinc to prevent rusting. The field magnets are made from the
best quality magnet steel, machine bent, and locked in position by a mild steel
rod. These are carefully hardened and magnetised to saturation by a special
process, and finally finished with black enamel. Each Generator is provided with
a reliable Shunt action, the springs of which are made of hard-rolled German
Silver, mounted on an ebonite block, designed to operate positively under all
conditions of working. The Generator handle is easily detachable for packing by
turning it in the reverse direction.

Fig. 117 shows our self-contained polarised Ringer No. 100 with one gong
removed. This is the standard Ringer of the British Post Office, and is made of
the best possible materials throughout. The adjustment of the armature is made
by raising or lowering the armature supporting yoke on the heavy brass pillars,
and locking same by the hexagon nuts as shown.
The holes in the gongs are drilled slightly out of the centre, so that when they
are rotated on the pillars, any desired distance from the striker can be
obtained. They are securely held in adjustment by a hexagon nut and cap lock

This adjustment is very simple, easy to effect, and absolutely permanent. The
gongs are made of heavy brass of special mixture which gives a loud and pleasing

The armature and cores are constructed of the finest imported Swedish iron,
the hysteresis loss of which is the lowest that has yet been attained. The
quality of the iron, combined with the fact that the coils are wound in regular
layers with the best quality insulated wire, gives an all-round efficiency that
cannot be improved. The spool heads are made of ebonite specially reinforced to
prevent breaking; the coils, wound with silk-insulated wire, are covered with
book-binders' cloth to protect the wire from mechanical damage, and the ends are
brought out with heavy-gauge flexible conductors soldered to copper tags.
When the Ringer is for use with tropical sets, the spools are wound with
enamel-insulated wire, which maintains, on account of its non-hygroscopic
qualities, a uniformly high insulation, and consequently more efficient working.

Where it is found desirable to fit an extension bell at some distance from
the telephone, the one illustrated in Fig. 118 will be found suitable. It
consists of our standard ringer fitted in a suitable box. The
woodwork usually employed is American black walnut, but it can be supplied in
teak if desired. The lid is hinged securely on one side and fastened on the
other by our standard screw lock.

We use machine screws throughout, the ordinary wood screw being deemed
undesirable on account of loose connections in case of shrinkage.

When Telephones are installed in the neighbourhood of electric light and power
mains, it becomes advisable to employ a protective device fixed separately from
the Instrument, thus shielding the latter against high and low-tension currents.
We recommend our C100 Protector for this purpose; it consists of a China Base on
which is mounted enclosed Fuses, Carbon Lightning Arresters, and Heat Coils,
with suitable Line and Earth Terminals.
