Electric warmers.-In a device for warming beds or other purposes wherein a heating element 2 is housed in a metal container mounted in a frame or cage, the element is short compared with the casing and is situated at a considerable distance from one end thereof so that the casing is heated partly by radiation and partly by conduction. The main portion of the casing is imperforate, the perforations 5 being confined to the end caps 4 or to part of the peripheral wall. The enclosing cage may be rigid and made of wickerwork or may be collapsable and comprise hinged stays 7 joined by longitudinal cords 8 or detachable bars, and engaging eyes 10 in squares 9 of fabric in the open position. The device may be stood on end for drying towels.
