Hercules Motor Wagon Co
of Levenshulme, Manchester
Manufactured by the Atlas Engineering Co.
R. H. Clark devoted several pages of his steam wagon book to the Hercules wagons, and featured three types of boiler. The first was of the vertical 'totally submerged type' patented in 1904 (No. 19073) by H. R. Perkins and John Barnouin Rowcliffe.. Another boiler was of the locomotive type, while the third example was double-ended, with two chimneys, having a central firebox in the form of a vertical cylinder, fed with fuel from above. Horizontal tubes took gases from the RH side ran to the RH smokebox, whence they were turned into horizontal tubes running the length of the boiler to the LH smokebox and exhausting through the LH chimney. A corresponding arrangement was used on the other half of the boiler. Clark included photographs of wagons with the three types of boiler, one belonging to the Great Central Railway and another to the Limmer Asphalte Paving Co.
