British Insulated and Helsby

Few collectors will have heard of this British company, but they were involved in telephones and cable manufacture from the earliest days, and they played a big part in the development of the Australian cable industry.

In 1884 J and G Crosland Taylor founded the Telegraph Manufacturing Company in Helsby in England. They made batteries, insulated wire and telegraph equipment. Within four years their lack of business experience was showing, and an inept manager was driving them into trouble. A new manager and a diversification into golf balls (made from gutta-percha, as used in their insulated wire) got the company out of trouble, but they found it hard to attract skilled staff to the quiet town of Helsby. In 1892 they moved much of the plant to a factory in Liverpool. Further diversification followed. They produced a range of products including bike tyres, and gained a large contract with the National Telephone Company for telephone wire and 26-pair cable. This established them in the cable market.

In 1902 they amalgamated with the British Insulated Wire Company of Prescot, in Lancashire. British Insulated started in 1890 and had built up a good market for insulated telephone, telegraph and electrical wiring. In 1899 they provided a submarine cable to run under Sydney Harbour. The amalgamation was a good move for both companies. British Insulated had the British and colonial patents for the new paper-insulated dry core cables and a large factory in Prescot to make it. TMC had a good range of telephone technology, which was a fast growing area, and many contracts for telephone cable. The new company became British Insulated and Helsby Cables Ltd .

In 1903 BI&H built a new factory in Edge Lane, an outer suburb of Liverpool. The factory was badly needed, as the existing factories could not keep up with the demand. Business was growing rapidly and telephone exchange equipment was being exported to, among other cities, Fremantle in Western Australia. The two phones listed in the Australian Post Office 1914 manual were possibly from this installation. They also exported large amounts of wire and insulators to the developing Australian railways. They seem to be well-known in Western Australia particularly.

BI&H was now building CB telephone exchanges as well as phones. Their CB switchboards were quite successful, and they equipped some large British cities with trunk exchanges for the British Post Office. The design followed Western Electric practice but was based on a version invented by J S Stone in the United States that had proved popular with the independent telephone companies (and avoided the Western Electric patents).

Although information on BI&H phones is scarce and ambiguous, some trends are emerging as collectors forward information. Rather than build their own phones completely, they seem to have bought in Western Electric phones and parts initially. A typical early phone will be standard Western Electric, but will carry at least one branded BI&H part as well as BIH circuit diagrams inside the case and bellbox. They started producing their own designs before the First World War, following the move to Edge Lane. The production dates of the WE phones are well known, so this gives us approximate dates for the BIH models.

Poole (1912) lists three examples of their CB phones. Some of these appear to use unbranded Ericsson transmitters fitted to an unusual “radial arm” whose purpose was “to accommodate to the different heights of the persons using it”. This could have been a useful feature in the days when the transmitters were less sensitive, but other companies managed to do without it The desk set has an extendable handset shaft “so as to accommodate the face length of any individual”. These phones are pictured on the next page.

Jim Bateman’s book “History of the Telephone in New South Wales” shows another and probably earlier design. It is a three box wall phone similar to a Western Electric pattern but fitted with an Ericsson receiver and a Manchester Shot transmitter in place of the usual Blake transmitter.

The Australian Post Office listed two BI&H phones in a 1914 technician’s manual. One was a magneto wall phone with dual receivers. This is probably the twin box model shown on the next page. These phones date from about 1886 to the early 1890s when the Solid Back transmitter was introduced. The other, from the circuit diagram shown in the manual, was a CB candlestick style (see next page). The circuit diagram shows provision for a second receiver. The phone appears to be a rebadged Ericsson model. The picture is from Bob Freshwater’s website (see Bibliography at the end of this chapter). Previous BIH candlestick phones were WE-based, but I am not aware of any WE candlesticks being fitted with a second receiver. In spite of this, the only candlestick known in Australia (so far) is a WE model, so maybe the APO manual has the incorrect circuit diagram from the later Ericsson model. By 1914 the APO had replaced many phones inherited from the old state telephone administrations, so the BI&H phones must have been reliable for the APO to retain them. In spite of this, they appear to be almost unknown to collectors. The APO also listed BI&H switchboards.

By 1914 BI&H was building CB wallphones to the now standard BPO pattern and these were listed in the APO’s 1914 handbook as Telephone No. 17. Although BIH's catalogue picture shows an Ericsson transmitter, it would more likely have been fitted with a Solid Back transmitter by this time, as per British Post Office practice. A similar magneto model was also made. Other companies made the same phone and only the numbers stamped into the back woodwork would identify it as a BI&H.

The next page shows BI&H’s “Pantophone”. This was a phonopore-type telephone for use on railway telegraph lines. Note that they used an Ericsson transmitter for the "ring" signal. Like most other companies they also produced a small range of intercom phones.

At the White City Exposition in 1908 one of the new American automatic telephone exchanges was demonstrated, probably by Strowger’s company Automatic Electric. It was a refined operation, rather than the clumsy early versions. The phones used the familiar ten-digit dial instead of the early “Knuckleduster” eleven-hole dial. The exchanges ran reliably on a two-wire subscriber circuit, which provided automatic ringing and busy tone. The new manager of BI&H, Mr Dane Sinclair, could see that this was the way of the future. He had actually patented an automatic switchboard in Britain in 1883 and he was well-placed to judge the efficiency of the Strowger design. He had been Engineer-in-Chief of the National Telephone Company, giving him experience of the competing Gilliland, Betulander and Lorimer systems and he knew their deficiencies. He urged the company to get the British rights to the Strowger system.

The Board agreed, and set up a new company to build the equipment – the Automatic Telephone Manufacturing Company. They acquired the rights in 1911. Although they were supposed to be a separate company to BI&H, the Post Office allocated them the manufacturer code of “H” (for Helsby”). The old company, BI&H, now concentrated on cables. The first British-built Automatic Telephone Manufacturing exchange was assembled from imported parts and installed at Epsom, and the company took over the Edge Lane factory from its parent. They began making their own equipment in 1912. This gave ATM a head start on other potential manufacturers like Ericsson and Western Electric. ATM began producing modified and reengineered versions of the Strowger equipment and was soon building a strongly British product. This was exported to Britain’s colonial markets as well. It also marked the end of BI&H as CB telephone manufacturers. The British Post Office had decided on a small range of standardized phones to their own designs and the BI&H phones were dropped. BI&H briefly produced a CB wall phone for the BPO, but it soon became evident that there was no point in them producing anything but automatic phones. The original company became British Insulated Cables in 1925 to reflect their new emphasis.

During World War 1 the Australian Government found that they had no local manufacturer of electrical wire, a vital military supply. They arranged a joint manufacturing deal between BI&H and local investors. The new Australian company was called Metal Manufactures Limited. Their factory was at Port Kembla, south of Sydney, where they produced copper rod for drawing into wire. By 1923 they were producing 3000 tonnes of copper rod per year, and they were diversifying into copper tube as well. They absorbed another local company, Austral Bronze Co. Ltd., who produced rolled brass and copper sheet.

During World War 2 the strategic value of these companies was realised by the Government, but it turned out that Australia still did not have a local manufacturer of insulated cables. A new consortium of Metal Manufactures, Olympic Tyres, and, once again, British Insulated was formed. It was called Cablemakers Australia Pty Ltd. Following another amalgamation in 1945 British Insulated became British Insulated & Callenders Cables, and was for a time the world’s biggest cable manufacturer.

BI&C eventually became part of the Marconi group of British companies, and it is interesting to note that Marconi appropriated the company’s previous history as its own. On its website under the heading “Marconi Celebrates a Century of Switching Innovation in Liverpool”, (December 4 2003), they modestly claimed “Known as British Insulated and Helsby Cables, Marconi began manufacturing manual telephone exchanges in Liverpool in December 1903. “ To the victor goes the right to rewrite history, but Marconi fell in its turn too. See the chapter on the General Electric Company for details.

The original TMC factory in Helsby was finally closed in 2002.
