Période

Used in Manitoba during the 1920's to the 1950's.

Canada

Used, presumably for repair work, on the St. Andrew's Lock & Dam, at Lockport, Manitoba from approximately 1920 to 1956. Officially opened by Prime Minister Sir Wilfred Laurier in 1910, the St. Andrew's Camere Curtain Dam is the only one of its kind in North America. It controlled the flow of the Red River and permitted boat traffic to pass to and from Lake Winnipeg.

Fonction

Electric tool used to hammer, chip, cut, and drill through numerous hard materials such as brick, concrete, metal and stone. Also known as a hammer-drill, this tool uses interchangeable bits or tool attachments for varying jobs. This specific electric hammer was used in conjunction with rectifier/control box 1969.0619.

Technique

The manufacturer claimed that the Syntron Electric Hammer could drill with ten times the speed of handwork, saved 80% of labour costs, and ran without breaking down. Because the Syntron hammer's piston was the only moving part, the manufacturer was also able to claim that it was low on maintenance costs because there was "no motor to burn out or gears to get out of order." (Ref. 1 - Advertisements). The tools' hammering motion was induced by the application of electromagnetic influence on a free piton inside the chamber of the hammer. Two vacuum tubes supplied the breaking action needed for the magnets to alternately grip and release the piston. The hammer drew its power from a rectifier/control box that could be plugged into a lamp socket for convenience. It had a high speed drilling capacity of 1 1/2" in diameter.
