Description : A wet cell battery consisting of a Pyrex glass jar bottom (a) and a hard rubber and zinc block cover (b). Jar is clear glass with maker's name embossed on one side in clear glass text. Jar is made in the United States with a registered trade mark. Cardboard tag on cover warns not to remove tag before oil is added. A short electric wire protrudes from the cover.
Commentaires : This wet cell battery is one of several that would have been used at one time. Used to power small lens buoy lights, or reflectors, using six volts at first then later 12 or 18 volt. Each one of these wet cell batteries would represent one volt, so you would usually have a row of at least six of these batteries to power the buoy light. Filled with fresh or salt water, they would last for a long time and would need to be changed every spring. Caustic soda/oil was added to the water and that stopped the water inside each jar from freezing. A zinc block is attached inside the cover and when in place is suspended into the water in the jar below, and the current would dissolve the zinc electrons. This dates from the mid 1950's to the 1960's and this style of battery would have been used at West Point Lighthouse. The West Point Lighthouse is called "the first of the 2nd generation" of lighthouses on PEI. It was the first one built by the new Department of Marine (also called Department of Marine and Fisheries). West Point was the first of the square towers, and the highest at 20.6 m (67 feet 8 inches) from ground to vane. Built by the firm of Messers. Mugridge and Co. from Shediac, New Brunswick for $4,559.59, it consisted of a square tapered tower of frame construction set on stone foundations. It had a 1 ½ storey, gable-roofed house with a lean-to storage shed. There were only two keepers during the 88 years before the tower was electrified in 1963.
