At Oil Springs, Keeping the Past Moving Takes New Wood

In September 2025, work at the Oil Museum of Canada gave part of its historic machinery an unmistakably new appearance. Crews were replacing wooden posts and rods in the jerker-line system. Curator Megan Sinclair told The Independent that deteriorating wood needed to be renewed so the equipment could keep running. [1]

That is a different kind of preservation from leaving an old object untouched. The wood was being changed in order to retain a movement.

At Oil Springs, the jerker line makes that distinction unusually visible. It carries power across the landscape through rods and wheels, linking a central source of motion to pumping equipment. Preserve only a detached pump and part of the story disappears: the connections explain how the system worked.

Power travelled across the field

Fairbank Oil Fields, a separate operating property in Oil Springs, describes its jerker lines as long wooden rods suspended near the ground. Moving back and forth, they transmit power horizontally from a powerhouse. Field wheels redirect that motion toward wells that are not arranged in a single straight line. [2]

The point was to share power. Lambton's oil museum history explains that John Henry Fairbank connected several wells to a common source rather than powering each separately. [3] The visible pump at a well was therefore only one part of a larger machine. Its movement depended on a network extending beyond it.

That network is easy to miss in a still photograph. A wooden rod can resemble a rail or boundary; a wheel can look like an isolated artifact. Their relationship becomes clearer when the elements are understood together: power source, connecting lines, changes of direction and the equipment at the well.

This is a description of historical machinery, not a guide to operating or approaching it. The interesting question here is what needs to survive for its history to remain understandable.

A demonstration is not the same as a producing field

The museum and Fairbank Oil Fields must not be collapsed into one place. Fairbank's account describes an operating oil-production system. The Oil Museum of Canada's own site description identifies the machinery at its Chalmers Power House as powering demonstration pump jacks through a field wheel and jerker lines. [2, 4]

The museum also gives that powerhouse a history of movement. It originally stood on Kelly Road and belonged to Dr. J. P. Chalmers. At the museum, its electric engine animates the connected equipment. [4] This is not a claim that every part has remained in its original location, or that the demonstration is identical to the neighbouring commercial operation.

The 2025 newspaper report belongs to the museum's maintenance story. It records replacement of deteriorating posts and rods, alongside work on the Blacksmith Shop. It also describes further building work as planned. [1] Those plans are not evidence here that every later project was completed.

Keeping those distinctions clear makes the heritage more interesting, not less. An operating field and a museum demonstration can explain related technology while having different purposes, maintenance histories and relationships to their original sites.

The age of a design is not the age of every part

A small object in Canada's national science-and-technology collection adds another scale to the story. Ingenium catalogues a C-hook made by Fairbank & VanTuyl Hardware Store in Petrolia, dated to the 1950s, as part of a pump used at the Fairbank field until 2011. Its technical description relates the machinery to Fairbank's 1863 jerker-line design and notes that components such as ropes and chains require periodic replacement. [5]

The catalogue therefore separates several kinds of age: the age of a design, the date of a component and the period during which it was used. Calling the technology nineteenth-century does not require every piece of it to have been made in the nineteenth century.

Nor does replacement make all questions of authenticity vanish. The sources consulted here do not provide a complete component-by-component history of the museum's equipment or a final inventory of its 2025 work. They cannot establish how much original material remains.

What they do show is a reason to look beyond age alone. The museum's renewed wooden lines keep a relationship between parts legible. The working field explains the wider system; the catalogued hook preserves one small piece of it outside that system.

Oil Springs offers more than old machinery to look at. It offers a way to think about what machinery is: not just a set of objects, but parts arranged to act on one another. Sometimes retaining that history means allowing fresh wood to carry an old motion.
