J. Tylor and Sons Limited of London was a company with a background in sanitation that moved into petrol engine manufacture in the 1900s.
Its engines were of medium sized and found application in buses, lifeboats and First World War military vehicles.
[1] J. Tylor and Sons Limited was then formed operating from the same brass foundry, as engineers making diverse items such as soda water bottling machines,[2] and diving equipment, but later they mainly focussed on plumbing and sanitation, brass valves and fittings, etc.
It dropped sanitary products in 1956 and merged with HRI Flowmeters moving to Burgess Hill, Sussex.
[13] Clayton and Company first started making petrol driven commercial vehicles in 1908 under the Karrier tradename, and they chose the Tylor engine.
To achieve the required volume, the production of the Tylor engines was carried out by other companies, such as Guy Motors.
In 1920, adverts for the Angus-Sanderson car claimed that (with one exception) "Tylor engines are fitted to every lifeboat operating on the coast of the British Isles".
In 1925 Tylor (JB4) Ltd was formed to provide spares for the 35,000 JB4 engines still in service, they acquired the remaining stock from the original makers, and other sources.
