Ransomes, Sims & Head, established 1789, was a major British agricultural machinery maker, and also manufactured aeroplanes during the First World War. In 1848, John Head joined the firm as an apprentice and invented an apparatus which enabled straw to be burnt as fuel in the firebox of portable and traction engines. This development, made in collaboration with a Russian engineer named Schemioth, proved a very useful one in countries where there was no wood available for fuel and where coal had to be imported at great expense. The Head-Schemioth system involved the provision of extra-large fireboxes and an apparatus, driven from the crankshaft by a strap, for feeding the straw into the firebox.
