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.

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the Diaphragm to touch the pole pieces, thereby rendering the Receiver practically useless until the Diaphragm has been replaced by a perfectly flat one.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 as below.
Code No. C103K.

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.

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.

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.

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.

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.


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.

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.

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.

Hook Switch
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

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 are used.

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 nut.


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 tone.

The polarising magnet is made of best quality permanent magnet steel, hardened and magnetised by our special process and heavily coated to prevent rusting.

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.

Extension Bells
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.


The method of fitting the extension ringer is shown in Fig. 103 where the jumper wire is removed, and the extension ringer put in the circuit.

Screw Lock
Fig. 122, our screw style lock, is the most serviceable form of fastening, as it not only obviates the use of a key, which is often lost when required, but also forms the means of securing the door to the framework ; it is impossible for these to come apart by vibration.

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.
