corporation o! Missouri Appucsaosruners,iosc,fsensi1vo.js1,is4 y 'l f ucisimalciss-r-s) t An object `of myinvention is to provide an electrical. appliance and basefor supportingl the appliance, the base being comparatively simple and inexpensive froma manufacturing stand- |fpoint.

. A mrtner object iste provide an 'elctricamepliance, especially 'of low mounted type, and a base which can be inexpensively formed yetwhich is durable and which is particularly adapted for mounting the appliance in a low position with .respect to a table top .or other supporting surface reinforced along 'its other two edges by elongated members associated with said other two edges to support the plate substantially. spaced from s.` table top or the like and' tospace the flanges thereof also above the table top.

Still a further object is to provide a supporting base in the form of a plate and a pair of members secured to opposite edges thereof, said .mem-

bers being grooved to receive the edges of. the. plate and thus-reinforce it and being formed with outwardly extending flanges tserving .as handles by which 4the'n.p1 iliaiice and basemay be carried. Still a further Objectis to provide a base' which Vis neat in appearance, yet. en cctively prevents the transmission'of heat from an appliance to a tabletop so that the appliance can be mounted 'relatively low andthe stability of lthe appliance thereby enhanced.

Still a further object-is vto provide a combined foot and handle member-'adapted tobe ino'un'd on an appliance base or thelike'r's'uch member preventing any scratching of asupp'orting surface and at the saine time provide a handle which is relatively cool. f 4Still a further object is toprovide a combined handle and foot member which spacesia tray o r base of'an electric appliance from a table top, such combined handle and foot -beingof low heatconducting material so that there is nofcontactV with a table top of a metallic support or the like which would permit passage of heat to the table top by conduction. A v

With these and'bther `objects in view, my inv 'vention consists in the` construction, arranse ment and'combination of the` various'- parts of the device, .whereby the objects contemplated are attained, as hereinafter more fully set forth.

accompanying drawing, in which: Figure 1 is, a'perspective vview of line 4--4 of Figure 1, showing how parts of the` base are assembled relative to each other. On the accompanying drawing I have used the reference character A to indicate generally an electrical appliance-'or electrically heated casing such as a sandwich toaster or the like.

A supporting basefor the appliance A Vis` indicated generally at B. The base B comprises'a afront elevation, partially secpointes' 'out in my claims, and mustrated in the an electrical appliance and base embodying my invention.v Figure 2 is an end elevation ofthe same, a portionl thereof being sectioned vFigure I.

plate vIl and a pair of elongated elements i 2 for f metal or other appropriate material and is generally` rectangular in shape. Two opposite edges thereof'are provided with flanges I6 which serve the purpose V of reinforcements against longitu- '--di nal bendingof the plate I 0. These are preferare supported in'spaced relationship 'to the sur- 30 face I4 by the elongated members l2.

Any'suitable'means may be provided for connecting the applianceA tothecentral portion of the plate lilpalthough I preferably use the means disclosed in` my Patent No. 2,040,369, issued May 12, 1936.k This means 'consists' of upwardly depressedand spaced apart portions I8 formed The portions I8 and 20 spacethe appliance fromthe base B s`o that I secure ample air circulation between the casing and base t0 effec-yA tively dissipate most of the heat transmitted from the appliance A to the sasepiare lo.

The elongated members l2 are formed of mate- 1rial which is a poor conductor of heat and may 'be formed of lwood if desired, which is relatively inexpensive. The members l`i2 are preferably shaped so 'as Ato have a longitudinal slot or groove 4on the plate I0, a plurality of these being provided in the edge of the plate Il through whichv feet for the material relative to a table top or theV a supporting foot and an outwardly extending flange 30 serving as a. handle. As shown in Figure 4, the ends of the sheet of material i. are pushed into the grooves 28 as indicated by the arrow a, after which a single screw may be driven home in the direction of the arrow b in a bore 34 provided therefor, a perforation 38 being prothe screw extends, as shown in Figure 3.

The flange 28 of each elongated member i2 is of sulcient height to substantially space the plate I0 above the surface il to secure space through which air may circulate between the lower surface of the plate l0 andthe supporting surface Il to dissipate the heat therefrom, the flanges i6 being spaced far enough from the surface I4, as shown in Figure 2, to permit such circulation yet give the appearance to the casual observer of resting on the surface I4. The elongated members |2 serve to reinforce the plate Il against lateral bending and also give anornamental appearance tothe base and provide handles which may be engaged for lifting the appliance from the surface i4 and carrying it from one positionto another; The plate lli is very inexpensively formed, as it is cut in rectangular shape and the only forming operations are rolling the flanges I6 and forming the projections Il.

The flanges I6 are very effective to prevent any longitudinal bending of the plate while the elongated members I2 effectively serve the purpose of preventing lateral bending thereof when assembled relative to the plate. members l2 can be inexpensively formed in a mold forming machine or the like and the manner of assembly obviously is very simple.

Some changes may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms o f structure or use of mechanical equivalents which may be reasonably included within their scope.
