Description: |
| This is the Canadian equivalent of US Patent 355,216. Examples of this patent radiator have been seen in a Southwestern Ontario house built in about 1902. The patentee moved from the Buffalo, NY, area, to Toronto in early 1887, established the Toronto Radiator Mfg. Co., and then in 1893 he moved back to Buffalo and established the International Radiator Co. He presumably sold his Canadian company at about the same time because it changed its name to the Dominion Radiator Co. The Dominion Radiator Co. thrived and sold a lot of Safford-designed boilers and radiators. The Buffalo company was not so successful and went bankrupt in 1913. Meanwhile, in 1912 Safford established the Safford Radiator Co. in Detroit to manufacture a new sheet-metal radiator that he had patented. That business does not seem to have been successful as we can find very few mentions of it.The most distinctive feature of these radiators is how the sections are joined. All sections are identical except for the two ends, and each of those middle sections has left-hand threaded top and bottom holes on one side and right-hand threaded holes on the other side. The sections are then joined with short nipples. The mating faces were machined and red-lead cement was used to seal the joints. Other radiator designs used long bolts to fasten all the sections together, but thermal expansion and contraction would lead to leaks. This Safford design was not unprecedented but it was well executed. |
