A cast iron, cube shaped AC meter with a small glass window and dial to turn the coin. 250-250 (clock) volt, 10 ampere. Before the introduction of Alternating Current (AC) power these coin slot meters were used in boarding houses, public halls, and in some domestic homes. They were often mounted on a wall just inside the front door. A pre-decimal shilling coin (10 cents) was inserted into the slot at the top right. The key below the slot was turned clockwise to activate the meter. This would allow a shillings worth of electricity to be used. (e.g. 1 Shilling buys 10 Kwh's) The meter automatically recorded each coin deposited and the power board would collect the accumulated coins each month. Payment was commonly referred to as ‘feeding the meter’.
