1903 - The Lodge brothers decided to go into business together and took out a patent for an improved system of high-tension ignition, which their father had discovered during his experimental work on electric condenser discharges. They named the company Lodge Bros.

1907 - The brothers built a new workshop and offices in Wrentham Street, Birmingham, and made the bold decision to take a stand at the Motor Show at Olympia.

1908 - In the meantime another inventor of resource based in Rugby was developing the sparking plug. Bernard Hopps had left the British Thomson Houston Company in 1908 to form his own Mascot company, and a year afterwards he took out his important patent for making a gastight joint in a plug by means of fused glass. 

1913 - Both Lodge Bros. and the Mascot Company had the common aim of producing the best possible sparking plug. Both firms had much to offer one another, and so in 1913 they decided to amalgamate, under the title of the Lodge Sparking Plug Company Ltd. this retained the Wrentham Street premises in Birmingham and the factory in Albert Street, Rugby.

As a result of the merger the hopeful motorist gained for the first time an efficient, gastight, non-detachable plug; and when a little later mica was introduced for the insulation of the centre-pin the internal combustion engine was carried a stage further towards reliability.

1914-1918 - WW1
Pepper Box type - Aircraft plugs manufactured for the Royal Flying Corps 
 

1916 - The factory in St. Peter's Road, Rugby was completed 1919 - name shortened to Lodge Plugs Ltd. 1920 - Publication of the first plug Recommendation Chart in the motor industry, from which a motorist could see at a glance the type of Lodge plug most suited to his vehicle. 1929 - The introduction of the C3 plug. This plug had a mica-wrapped core round the electrode, and was finished externally with a steatite sleeve as a protective cover. Its versatility was shown in 1929 when Sir Charles Kingsford Smith chose it for his record non-stop flight from England to Australia, in the "Southern Cross." It was the parent of the well-known BR series of Lodge motor-racing plugs, and a stepped-up sales campaign soon made it extremely popular with the ordinary motorist. 1931 - Research work that was started around 1926 resulted in the A30 and the KR3 series being launched. The latter went on to win a great name for itself as the plug used by the British team in the Schneider Trophy Race.

1935 – Responding to demand from the motor racing fraternity, alumina Insulators, were introduced. This pink ceramic that came from sintered aluminium oxide, possessed remarkable thermal, electrical and mechanical properties. As an insulator it had all the advantages of mica, yet none of its drawbacks.  1937 - George Eyston in "Thunderbolt" raised the land speed record to 345 m.p.h. A record he broke the following year, taking it 357 m.p.h. In Eyston's records Sintox was already playing its part, standing up stoutly to temperatures and pressures under which the older types of insulation would certainly have failed. 1938 - Alec Lodge died

1939/45 - Invention of the 'S' alloy and the Thermo-Couple Plug. The firm was registered as "an undertaking under the Essential Works Order." Plugs were produced for almost every kind of internal combustion engine - fitted in motor torpedo boats, landing craft, air-sea rescue launches, all varieties of military vehicle (including tanks) and stationary power equipment. Special adaptations of the sparking plug were also designed for flame-throwers. The majority of production, by far, was for the R.A.F. and the US Air Force, which between them absorbed seventy-five per cent of total production.  President Roosevelt in an address to Congress at the end of 1944 said: "Reference is made to the British aircraft supplies to the Americans…….before and during the Battle of Britain, when the R.A.F. had to work its out-numbered planes around the clock and the Spitfire and Hurricane engines got punishing treatment, the British developed a new type airplane spark plug ….. Since early in 1943 virtually every United States Flying Fortress has taken off from British bases with these plugs in each of its four engines. It would be impossible to estimate how many thousand United States bomber crews may since then have owed their lives to these spark plugs, but the performance record of the plugs speaks for itself."

1992 - The Morgan Crucible Company plc bought the Rugby factory from Smiths Industries and traded under the name of Morgan Matroc Limited. Jan 2002 - The Rugby site changed its name to Morgan Advanced Ceramics  March 2005 – Relocation of facility from St Peter’s Road to Central Park, Rugby June 2005 – Official Opening of the new site by The Mayor of Rugby, Cllr Richard Lane
