support electrically heated sad irons or similar implements when the same are not in use.

cOne of the objects of my inventionl is to provide a device. ofthe above-indicated character whichshall be simple, compact and durable in construction, inexpensive to assemble and manufacture, and particularly adapted to prevent the conductionor transmission of lheat from the heated body to the surface upon which the stand rests.

ccording to my invention, l provide a supporting structure of this general class which comprises a plurality of punched or pressed sheet metal parts which may be formed at relatively small expense, and may be readily assembled and united in such manner as to ed'e'ctively perform their intended functions and also provide a stand which shall be particularly strong and adapted to withstand careless and rough usage.

lin the accompanying drawing, Figure 1 1s a side elevational view of a supporting structure embodying my invention, and including an electrically `heated sad iron in position thereon, and Fig. 2 is a plan view of the device shown in Fig. l with the sad iron and a portion of said device removed for the sake of clearness. Figs. 3 and I are l views respectively similar to Figs. l and 2 of a modified' form of my-invention, a portion of Fig. 3 being shown in section.

Referring particularly to Figs. 1 and 2, a

heated body l, which is shown for illus-A trative purposes as an electrically heated sad iron, but` which may constitute any other heated implement, rests upon a supporting structure or stand 2. rlllhe stand 2 comprises a plurality of plates' 3, 4 and 5 which are preferably constructed of sheet metal and which are substantially 'of the same shape-or contour as the sad iron l, or

other body which the stand 2 is adapted to support. I

The plate 3 constitutes a supporting plate for the sad iron l, and its outer side edges 6 are disposed at substantially right angles to the main portion thereof `to form an upwardly projecting outer flange which is adapted to maintain the sad iron in position: A portion 7 at the heel of the plate 3 1s slightly inclined with respect to the main body of the plate in order to assist in slidmg the device l into its proper position upon the stand in case it is hastilyl or carelessly placed thereon. A plurality of downwardly projecting integral spherically curved portions 8 are also provided upon the plate 3, one of which is conveniently located near the toe of the plate while the other portions are located at the heel thereof. Obviously, the plate 3 may be constructed and formed in any well known and desired manner, although I ind' it preferable to punch the same out of a sheet metal blank and to press the spherically curved projecting portion 8 therein in accordance with well known practice. ln this manner, the necessary work may be accomplished with facility and comparatively small expense, and the plates thus produced are particularly adapted for the purposes intended.

Plate 5 constitutesa supporting base, and

although shown somewhat larger in size than the plate 3, to accommodate a larger iron, it is otherwise similar and is constructed in the same manner as that already described. r)The plate 5 embodies downwardly projecting outer flanges 6a, an inclined end ange 7a, and a plurality of upwardly projecting integral spherically curved portions 8a which are'correspondingly located with respect to the spherically curved portions 8 of the upper plate 3.

rThe intermediate plate 4, which constitutes a baffle or a heat-radiating plate that may or may not be used, rests upon the up,- wardly projecting portions 8a, and, disposed upon the plate 4;,'is the upper supporting plate 3 having its downwardly projecting integral portions 8 located directly abovethe projecting portions Sain such manner that the several plates are in contact or engagement only at three points, which, by reason of the shape of the projecting portions 8 and 8a, are `of comparatively small area.

order to secure vthe several parts rigidly to- Veo gether to form a strong and unitary structure, a plurality of rivets 9, or other suitablemeans, are employed, said rivets 9 or other means being located substantially at the points of engagement.

lIt should, of course, be understood that the plates 3, 4 and 5 may or may not be of substantially the same size, but, in many cases, it is desirable to make them of somewhat different sizes, as shown in the drawing, in order that the stand may be reversible, whereby it is adapted toI accommodate different sizesv of sad ironsor other implements.

When the stand is used for supporting a heated body, such as the electrically heated sad iron 1, inappreciable amounts of heat are transmitted to the supporting base plate 5 by reason of the fact that a minimum number of engaging points are provided, and said points are of comparatively small area, so that very little heat is transmitted therethrough. Furthermore, the intermediate baiiie or radiating platev 4 serves to obstruct the direct downward radiation of heat from the heated body 1 and also tends to radiate such heat freely into the atmosphere. Attention is also directed to the fact that the base plate 5 is adapted toengage any vconvenient supporting surface (not shown) only at the bottom edges of the side flanges 6e.' Thus an air space is provided beneath the base plate 5 which assists in. cooling the same and preventing undesirable heating of the supporting surface. Moreover, a very small portion of the base plate 5 is in'actual engagement with the supporting surface, and a large portion of the plate 'is exposed for radiation so that the amount of *heat actually transmitted to the vsupporting surface is comparatively negligible.

Referring now to Figs. 3 and 4 of the accompanying drawing, an electrically heated body 1 is supported 'upon a stand or structure 2 which comprises an upper supporting plate 3 and a lower base plate 5 which are similar in construction to the plates 3 and. 5 shown and described with reference to Figs. 1 and 2, and which are disposed the one upon the other and secured together in a manner similar to that which has already been set forth, and on account of this similarity -in structure and assemblage, no further detailed description thereof is deemed necessary. It should be noted, however, that the upper plate 3 is provided with a plurality of upwardly projecting spherically curved portions 10, one of which is disposed at the toe of the stand 2, while the remaining projections are svmmetrically located at the heel thereof. The projections 10, just referred to, serve to support the heated body 1 upon three points of very small area so that the direct conduction of heat to the plate 3 is very small. The plate 5 is also provided with similarly disposed downwardly projecting spherically curved portions 10 which are adapted to serve the purpose of supporting a heated body 1 when the stand 2 is reversed in position so that the plate 5 constitutes the upper supporting plate.

In many cases, it may be found unnecessary to provide an intermediate baiiic or radiating plate such Aas is shown in Figs. 1 and 2, and no such plate is employed in the supporting structure shown in Figs. 3 and 4, the upper and lower plates 3 and 5, respectively, being in direct intimate engagement through their oppositely projecting portions 8 and 8a. t will, of course, be understood that, if desired, an intermediate plate such as is shown in Figs. 1 and 2, may be inserted between the upper and lower plates 3 and 5 of the supporting stand shown in Figs. 3 and 4, or it may be found desirable to construct the supporting stand in accordance with Figs. 1 and 2 but with the intermediate radiating plate omitted.

Obviously, many other variations and modifications in the structural details and arrangement and location of parts may be effected without departing from the spirit and scope of my invention, and I desire that only such limitations shall be imposed as are indicated in the appended claims.

I claim as my invention:

1. A stand for supporting heated bodies comprising a plurality of plates havingsubstantially plane surfaces and having correspondingly disposed integral curved portions that severally coperate, 'the one with the other, in pairs, and means for securing said plates together.

2. A stand for supporting heated bodies comprising a plurality of similar plates having substantially plane surfaces and having correspondingly disposed integral curved portions that project laterally beyond the adjacent surfaces of the plates, into proximity to each other, and an intermediate plate interposed between the curved portions of said first mentioned plates.

3. A sad iron stand comprising a sheet metal base plate having a plurality of upwardly projecting integral portions and a substantially plane portion, a second sheet metal plate resting thereon, a third sheet metal plate having correspondingly located downwardly projecting integral portions adaptedto rest upon said second plate directly above the first-mentioned integral portions, and means for securing said parts together at their points of contact.

4. A supporting'structure for heated bodies comprising a plurality of sheet metal plates having correspondingly and oppometier sitely disposed pressed portions and an intermediate plate adapted to engage said pressed portions at a plurality of points, and means for rigidly uniting said parts at the points of engagement. l

5. A -sad iron stand comprising a sheet metal base plate having downwardly projecting edges and a plurality of upwardly projecting integral pressed portions, a radiating plate resting on said portions, and a sheet metal supporting plate having oorrespondingly located downwardly projecting portions adapted to rest upon said radiating plate, and a plurality of rivets for uniting said parts together at their engaging por- [15 tions.
