ELECTRIC HEATER Filed July 6, 1927 INVENTOR. GEORGE [4704' ATTORNEY.

Patented Apr. 8, 1930 UNITED STATES P-{ATFENT OFFICE GEORGE EATON, 01 OHIO, ASSIGNOB, BY MESNE ASSIGNMENTS, TO PAN ELECTRIC MANUFACTURING CORPORATION, A CORPORATION OF OHIO nLEc'rnIc HEATER.

Application filed July 6, 192 Serial No. 203,771.

This invention relates to improvements in electric heaters and more particularly to that type known as toasters, designed for use upon the dining table.

The object of this invention is to provide such a device in which the structure is extremely simple and in which the parts are readily assembled or disassembled without the use of any screws, bolts or othervsuch securin means.

Another object is to provide such a device in which the supporting frame is a single integral part, preferably in the form of a casting of glazed porcelain or the like. I Another object is to provide such a device in which the heating element includes a resilient member which may be readily placed in assembled position inthe frame in such a manner that there will be efiected a spring engagement between said parts.

Another object is to provide such a device in which the main supporting frame has 1 means for automatically inclining the bread or other such material towards the heating element.

Another object is to provide an improved grid means against which the bread or other such material may rest, such means having spring engagement with the frame, and serving at the same time to maintain the several parts in assembled relation.

Another object is to provide such a device which possesses an extremely artistic appear ance and is also completely insulated by V11- tue of the particular composition of 'the frame. 7

Other objects will appear from the following description and claims when considered together with the accompany ng drawing.

Fig. 1 is a side view of my improved toaster; Fig. 2 is an end view of the same; Flg 3 is a sectional view taken on line 33 of Fig. 1; Fig. 4 is a sectional View taken on line H of Fig. 1; Fig. 5 is a detail view taken on line 5-5 of Fig. 1; Fig. 6 is a view corre sponding to Fig. 5.but showing the bottom part; and Figs. 7 and 8 are detail views of the engagement of the lower and upper ends, respectively, of the gr d wlres with the bottom and top plates or strips.

same in position.

The frame, as here shown, consists of a one-piece-casting of glazed porcelain or the like and has the end portions 1 extending up from the base or bottom 2,. and the top portion 3. The frame has the integral legs 4 and its bottom is slightly curved, as indicated in the drawing. The sides 5 are-also integral with the baseand extend upwardly therefrom mspaced relation to the main part of the frame'so as to provide side channels on opposite sides of the main part of the frame. These channels are adapted to receive and support the sliced bread or other such material for toasting, the bottom of each channelbeing slightly inclined downwardly towards the main part of the frame so as to always tiltthe bread towards the heating element which is supported in the main part of the frame.

The top and

bottom grooves

6 and 7 are formed in the top and bottom parts of the frame and are adapted to receive the

grooved middle portions

8 and 9 of the top and bottom retaining plates or strips 10 and li which may be of metal or other suitable material. These strips have

side flanges

12 and 13 which engage the to and bottom parts of the frame on theopposlte sides of the

grooves

6 and 7. The narrowed

end portions

14 and 15 of these strips engage in the

grooves

16 and 17 provided in the inner sides of the upright end portions 1, although this feature may be omitted if desired, the several parts being otherwise sufficiently maintained in position.

The grooves in the strips 10 and 11 are adapted to receive the top and bottom edges of the sheets of mica 17 or other similar electric insulating material, so as to maintain the The mica sheet is here shown as having two

parts

17 and 17 about which the electric resistance 18 is wound, the two ends of which are connected to the binding post 18 extending through the -frame. The mica sheet is of more or less a resilient nature and is sprung into engagement with the top and

bottom grooves

8 and 9. The resilient wires 20 are also sprung into engagement with the holes 21 in the

flanges

12 and 13 of the metal stri s, the extreme end portions of these wires eing bent up an down so as to project through the holes while the intermediate ortions20 extend in a substantial lateral direction and seat in the deressions or seats22 which are formed in the

anges

12 and 13 and extend from the holes 21 in. a direction substantially at right angles to the general length of the strips. In this way, the rods or wires are prevented from accidental turning. These grid wires 20 serve also to maintain the several parts in assembly since they extend and exert a certain spring engagement between the top and bottom strips 10 and 11. Thus the wires 20 have a dual function, namely to support the bread or other such material in toasting relation to the heating element, and also to maintain the parts in assembly. The spring nature of the sheet of mica might be considered also as serving to maintain itself inassembly with the other parts.

The following are a few of the advantages which result from my improved structure. In thefirst place, the main frame is formed of a material which is capable of very artistic appearance but at the same time is of a very durable nature and is extremely well adapted for this particular use because of its property as an electric insulator. The porcelain will also withstand a very high degree of heat without danger or depreclation. Then, too, the parts, comparatively few innumber, are capable of being very readily assembled and are maintained firmly in assembled position without the use of screws, bolts or other such securing means. Furthermore, the channels with their sides 5 not only serve to maintain the bread or other such material in roperposition, but serve also to conserve t e heat by deflecting and radiating a certain part which would otherwise be lost. And, too, because of the porcelain frame, my toaster can be recognized as a part of the china set of dishes, and can be given the same pattern of decoration as a means of furthering this idea of harmony.

What I claim as new is:
