are a plurality ci" contact plates 9, said plates being arranged at the ends oir1 alternate partition Walls for the grooves e and each 'plate being ci? such length as to be disposed across a pair of adjacent grooves. This permits the ends of the heating coils 7 to he en aged vvith the plates 9,' said coils tie-ing had in contact by means of the Wood screws l() vand from this construction it will be seen that all of the coils will he placed in outer coils is engaged with anv additional contact plate ll there being two plates in 'iA further object of the invention resides View of the fact that. there are tivo coils and in providing a device havin a hase formed from these plates extend Wires 12 and 13 ition an provided with which connect with a pairv of terminals 14 and l5. l'lf'vires may' he engaged with these terminals from the main circuit and as the circuit is completed, the coils will give forth heat for cooking or other purposes. l

ln order to provide for toasting on this device, l provide a grid plate 16 which is adapted to he secured vto the `frame l, said plate being provided with a plurality of slots or channels to aline with the slotseiof the insulating base 3. By arranging the slots in the grid plate so as to aline with the longitudinal channels of the composition body, the heat units which radiate from the heating coils 7, may readily pass throughl said slots to be quickly absorbed hy the artiv pointed out in the cles placed on said grid plate. A cover or y top plate 17 is also provided, which maybe readily removed or entirely eliminated, if

In Fig. 4- l have shown a slightly modi fied form et the invention wherein a threeheat arrangement of coils is provided, vthe device being otherwise, in structure, the l same as the form just described. In this In describing my invention, I shall refer form, the insulating base 3 is provided With eight grooves Ll as in the other form which communicate with the front and rear and 6 respectively and mounted in the groove or channel 5 are the two contact-,strips 18 and i9, the ends of which aline respectively with the first two grooves and thc central tivo grooves l. Mounted in the channel are the additional Contact strips 2O and 2l. the ends of which respectively aline with the second, third, sixth Vand seventh channels or grooves 4, of the at right angles to the first mentioned, leach hase. Mounted on the under face of the hase 3', at the end thereo'lz having the channel 6 therein a heating vcoil 7. Secured in the therein are a pair of contact strips or plates 22 and 23, the ends of Pthe-tormer aliningA .with the planes-of the first and fourth channels,-\vhile the ends of the latter aline with the planes of thetifth and eighth channels.

rcoil in the secondchannel connects the opposite end of the strip 18 with one end of the strip 20. The coil in thethird channel connects the opposite end Aot thestrip 20 'I with one end of an vadditional strip' 24 'mounted von the' under face of the base 3 at the, end having the channel thereiniwhile the'coils in the tivo central channels connect the ends of the strip 19 with the inner op- `posed ends of the strips 22 and 23. The coil in the sixth channel connects the opposite end ofthe strip 2i With one end of the strip 21v and the coil in the seventh channel connects the opposite end of the strip 21 with an -additional contact plate 25- in the channel 5": The coil in the last and eighth channel connects the one end of the strip 23 with a still further cont-act plate 26 in t-he channel 5 and Wires 27- and 2S Whichlead respectively from said plates 25 and 26 con' nect'with a pair ot terminals 29 and 30 respectively. AAn additionaly 'terminal 31 mounted in the forward end of the base in alinement with the aforesaid terminals connects by means of a Wire 32 to the strip 1S. A iexible cord 33 carried onthe central terminal 29 carries a porcelain plug 34 which may be connected with the terminal 31 to allow the maximum heat to be obtained through the circuits s 29 and 30. From this description of the circuits in. this form, it is obvious wherebythe heat in this device may be varied.

From the foregoing it Will be seen that I have provided a simple electric'heater and While I 'have particularly described the ele- `ments most Well adapted to perform .the

, functions set forth, it is obvious that various changes in form, proportion and in the minor detalls of construction' may be resorted to wit-hout departing'from the spirit yor Asacrificing any ot the `principles of the invention. 1
