Thomas Aveling was born at Elm in Cambridgeshire in
1824. In 1858 along with Richard Porter he founded Aveling & Porter at
Rochester in Kent for the manufacture of steam engines and ancillary
equipment. Aveling and Porter were at the forefront of agricultural steam
engine design and were the first to introduce the hornplate traction engine
which has been the hallmark of British traction engine design from the
1870's onward. Over the years a |

great variety of engines were produced including
portable engines, agricultural engines, steam lorries, ploughing engines,
road haulage engines, tram and small industrial rail engines although the
company is perhaps best remembered for steam rollers of which considerable
numbers survive preservation. |

The 1920's
were the heyday of the great road steam manufacturers, but they suffered a
rapid decline in the 1930's with the introduction into heavy haulage and
agricultural use of the more economical diesel engine. In 1933 Aveling &
Porter moved to Grantham and merged with Barford Perkins to form Aveling
Barford and continued for many years producing heavy earth moving equipment.

bearings to each axle. The wagon is close coupled with a stirrup attached to
the front axle for correct weight distribution and easy steering. 3ft - 6"
