Technical history:

These jumpers were part of a tool kit used by an arc lamp repairman, called a trimmer, to maintain and service street lamps.


The first arc lamp in Canada was installed in the Davis House hotel in Winnipeg on March 12, 1873. Five years later, J. A. Craig demonstrated the Yablochkov candle and arc technology in Montreal. Although the first arc lamps were open — they did not have globes — by the 1890s almost all commercial arc lighting used safer and more stable enclosed lamps. These lamps required extensive cleaning and regular maintenance. As the incandescent technology became available, the use of arc lamps declined by the 1920s.
