How does a Teasmade work? The alarm on the clock is set and, when it sounds, an electric element in an attached kettle switches on to heat the water. Pressure enables the boiling water to decant through a tube in the kettle lid into an adjacent teapot or cup, making the whole unit pivot forward, activating the light and alarm. All resulting in a perfectly brewed, reviving cup of tea.
Born in 1866 in Manchester, electrical engineer Samuel Rowbottom from S. Rowbottom and Co applied for a patent for what he called an Automatic Tea Making Apparatus. His model featured a clockwork alarm clock, gas ring and pilot light. The gas pilot was required to be lit at all times, which made it a safety risk. Later Teasmade models became more practical with electric versions.
The Whanganui Regional Museum's collection features Teasmade models. A 1940s Hawkins Tecal model which runs on voltage 200/250 and has an alarm clock on the front with a light bulb connection on the top. A hot water aluminium kettle plugs into the back of the clock. It is square with a spout on the lid for steam to escape and a black handle. The body of the Teasmade is a cream colour and it has an electric plug and cord attached to the side.
The pictured model is a Goblin Teasmade from the 1970s. It has a white plastic base with two square pads for holding a kettle and a teapot. The kettle is square and made of stainless steel with dimpled sides and a metal tube on top which drips into the teapot. An electric cord at the back of the base plugs into the kettle to heat water. The teapot is square, ceramic and has a round, black fitted lid and a squared handle.
The name Teasmade is an example of a generic trademark, introduced by Goblin Ltd but now commonly used to refer to any automatic tea-making appliance. Perhaps it's time for a revival.
