E MB RACING the past

While reclaiming original radiators from a 130-year-old house in Toronto’s Annex neighbourhood, a crew from Ironworks Radiators Inc. discovered a Walco 24-in. pipe wrench from the J. J. Walworth tool factory. The pipe was found in the boiler room of the 2.5-storey, Victorian semi-detached home. Ironworks has returned the wrench to its former glory in honour of those who made a living with it. It will be hung on the wall at Ironworks’ Etobicoke, ON location

In the 1840s Walworth and Nason, which at the time was owned by J.J. Walworth and Joseph Nason, introduced the world to steam heating systems. Over the next few decades the company’s machinists had to create much of what it needed to build these systems, such as fittings, valves, radiators and tools, including the Stillson pipe wrench.

Today, the term “Stillson” refers to a wrench style, while the patent for the original adjustable wrench designed for iron pipes was issued to Daniel Stillson in 1869. He was employed by Walworth and at that time intellectual property remained with the individual rather than the company they were working for.

The actual amount Stillson received in royalties over the course of his lifetime depends on who is reporting it, but the range is $80,000 ($2.6 million today) to $100,000 ($3.3 million today).

A.O. Brungardt, who also worked at Walworth, registered the patent shown on Ironworks’ restored “Stillson” type wrench in 1929.
