Meet the 1917 Farquhar Road Engine
I took these pictures of the 1917 Farquhar Road Engine
when it was on display at the Vancouver Island Exhibition in Nanaimo during the
summer. I involve students in examining these several photos during class
discussion. It demonstrates the design features of an industrial machine that was
manufactured using no welding.
This is an article about the group that restored this machine.

(The lower hinge on the boiler door appears
to be repaired by welding.)
Everything is cast parts and plate riveted or bolted together.
It is particularly fascinating to see the wheels which
are completely bolted together of hundreds of individual pieces. This factory
production power unit was available for sale brand new in 1917. It was high
tech riveted lap style construction; before it was challenged by a new process,
fusion welding.
This transformation
in engineering design would save enormous amounts of labour in assembly. Parts
often needed to be hand filed one by one. The amount of material saved, holes
made and rivets hammered. The complexity and
shear number of parts required to manufacture what is a simple machine, especially
compared to an internal combustion powered vehicle.
Students can clearly see that this steam
powered machine shares design cues with steam locomotives. This rivet assembly technology
was also key to large commercial construction in 1917. We can immediately think
of skyscrapers and bridges in New York with iron workers with hot tongs and
others with the pails of rivets and the air hammers. This was the pinnacle of
riveted design and assembly technology.
