Abstract
216,263. Burke, W. March 22, 1923. Alarms operated by expansion of liquids; e l e c t r i c alarm systems. - An electric alarm for indicating the required heating or boiling of liquids in containers is combined with the electric apparatus for lighting fires described in Specification 2 1 6 . 250, [Class 75 (iii), Lamps &c., Details of]. A thermometer 2 has electric contacts 1, 4 whereby the mercury 3 closes an electric alarm circuit 7, 11 when the required temperature is reached, the contact 4 being connected to an outer metallic casing 5 immersed in the liquid in the kettle &c. The leads 7, 11 are connected to a plug, which is inserted in the plug holes 41<1>, 42 of the wall plug board 30 of the fire-lighting apparatus, so that the buzzer 37 is sounded when the kettle boils.
