1315168 Electric toasters MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 10 Nov 1970 [14 Nov 1969 11 April 1970 24 June 1970 15 July 1970 26 Sept 1970 30 Sept 1970] 53500/70 Heading A4D [Also in Division H5] An electric toaster in which bread is toasted whilst in contact with heater elements comprises two spaced stationary planar electric heating elements 2 in the central region of a casing (1), Fig. 5 (not shown), an outer movable planar heater 2 on each side of the central pair, a spring 15 urging the outer elements towards the central elements, a lever 11 for moving arms 9, to which the outer elements are pivoted, to cause separation of the outer e'ements on upward movement of lever 11 caused by a spring 14, a bread-carrier frame (8), Figs.6a, b (not shown), attached via a plate 7 to lever 11, and having portions located in each toasting chamber defined between a central and an outer element 2, latches 12, 16 for retaining lever 11 and frame (8) lowered, and means, such as a relay 17, for releasing engagement of the latches. The central elements 2 are mounted on a frame 3, and apertures through a base-plate and an upper aperture b allow upward passage of air between the central elements. Metal guides 20 are located in each toasting chamber so that the bread is confined to the effective heating region of elements 2 and to prevent overheating of the elements if a bread slice is not inserted in a chamber by preventing contact between the outer and central element 2 thereof. The elements 2 of one toasting chamber may operate separately from those of the other chamber. The frame (8) comprises a main frame with a portion in each chamber, to each of which portion an auxiliary frame member (21) Figs. 6a, b (not shown) is attached by leaf-springs, the frame contracting in width as outer elements 2 move towards each other by movement of members (21) towards the main frame. Each heater element may comprise conductive wires incorporated as part of the warp and weft threads of a glass cloth, the whole being covered with heat-resistant resin, such as silicone enamel or polyimide.
