Can someone identify this engine, said to have worked at British Oil and Cake Mills in Kent? http://abpr.railfan.net/abprphoto.cgi?december02/12-17-02/BOCM-St_Vincent2-ER-101260.jpg ryarger@rypn.org |

This photo says made by Aveling & Porter. I assume this is the same firm that produced steam tractors and road rollers? Do any of these still exist? http://abpr.railfan.net/abprphoto.cgi?december02/12-17-02/BOCM-Sydenham1-ER-101260.jpg ryarger@rypn.org |

Can't help you with info on these engines Bob but they're were some pretty interesting engines used by Guiness in Ireland. 0-4-0 narrow gauge engines that could be lifted and dropped into a broad Irish gauge contraption (almost like a cradle) that transferred the power from the wheels of the narrow gauge engine to broad gauge. Don't know if any of those survived. Joshua joshua@joshuakblay.com |

It is the same firm that made the Road Locomotives. There is at least one preserved in the UK. My questions are, how do you get a single cylinder locomotive moving if the piston is at the extreme of the stroke and on level ground? How many firms made single cylinder locomotives? Very interesting little creature. Roger > This photo says made by Aveling & > Porter. I assume this is the same firm that > produced steam tractors and road rollers?

Looks more like a compound than a single cylinder? If so It's probably quartered like a stationary or marine engine |

I had considered that until I read the following description about another Aveling Porter: 'It was of 0-4-0 wheel layout with a single over-type cylinder driving in typical traction engine manner through an open gear-box with sliding gears and a gear-wheel meshing with cog wheels fixed to the inside the right-hand driving wheels of both axles'. That seems to fairly well describe the layout of the ones shown. I would assume (you know what happens when you assume) that it is a piston valve locomotive and that is why there are two different size cylinders. As for the Guinness locomotves mentioned above, there are at least 5 of these 18" gauge engines still in existance.

OK, next question: what's the purpose of the connecting rods attached right to the axles? |

The wheels are connected to the cylinders by a gear wheel set between the driving wheels. It thus tends to push them apart. The "rods" are maintain correct spacing. Only a small number of these locos were built. They used traction engine technology. jimlivesey@btopenworld.com |
