Information Sources

• Repair manual and parts list dated 1953-01-19: "Fairbanks-Morse Electric Motors for Domestic Water Systems / as manufactured by / Electric Tamper & Equipment Co. of Canada Ltd. / Montreal Toronto" The warranty section says, "The Canadian Fairbanks-Morse Company Limited warrants each new Fairbanks-Morse Single Phase Motor..." The motors themselves are ¼ and ? HP split-phase and capacitor-start types. All but one are four-pole motors.
• Known as a motor maker from a 1 HP induction motor with the "Tamper" brand name.
• 1/2 HP motor from Rockwell Manufacturing Co. of Canada, Ltd., "manufactured by Tamper Division Canada Iron Foundries Ltd."
• 3/4 HP "TECO" branded motor from Eaton's of Canada. The motor label does not explicitly identify the manufacturer but a cardboard tag in the electrical connector box identifies "Electric Tamper & Equip. Co. of Canada Ltd., 160 St. Joseph St., Lachine, P. Q." Brian Kachadurian pointed out to us that "The base and capacitor on the 3/4 hp motor are identical to Packard Electric motors built for Sears." We do not know why these parts would be the same—whether one company was supplying to the other, or both were using the same third-party supplier, or if the two companies had some ownership connection.
