7 Claims.

195,517, filed March 12, 1938 which became Patent No. 2,147,036, on February 14,1939.

A further object of the present invention is to provide a relatively fiat sadiron which can be conveniently folded to a compact position and yet in which the dissipation of heat rising from the sadiron is eiiectively taken care of by a plurality of spaced cover plates which provide a relatively flat cover means for the sole plate and heating element. I

Another object is to provide a sole plate having in it a heating element and to provide a cover plate for the heating element and cover means 25 for the cover plate consisting of additional plates spaced from each other and from the cover plate so as to provide between them air spaces to prevent excessive heating of the additional plates and in turn excessive radiation of heat to the users hand, my construction being such that these objects are accomplished without the necessity of using a relatively high casing or shell over the sole plate as in usual constructions.

A further object is to provide means formed in the outermost additional plate to receive ends of a handle for the sadiron.

Still another object is to provide a nose piece on the sole plate designed to cover the space front edges of the additional plates to prevent catching of the edges thereof on fabrics being ironed.

Still a further object is to providethe additional plates extending rearwardly to act as a heel rest and thereby in conjunction with the rear end of the handle to serve as a means to support the iron in up-ended position.

With these and other objects in view my invention consists in the construction, arrange- 6 ment'and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawing.

Although the invention is susceptible of a variety of embodiments, itis unnecessary to fully describe and illustrate more than one in order to give a full understanding of the invention both from its structural and functional standpoints.

Accordingly, I have illustrated structured and desirable embodiment of the invention in the accompanying drawing, in which:

Figure 1 is a plan view of a sadiron structure embodying my invention and showing the handle thereof removed with the handle supports extending up from the iron shown in section and the heating element of the sadiron shown dotted.

Figure 2 is a longitudinal sectional view on the line 2-2 of Figure 1.

Figure 3 is a vertical sectional view on the'line 33 of Figure 1; and

Figure 4 is a vertical sectional view on the line 4-4 of Figure 1 showing the heating element terminals and their relation to cover plates of the iron.

On the accompanying drawing I have used the reference character S to indicate a sole plate and H a handle for the sadiron structure. The sole plate S is provided with a heating element groove III which may be of any desired or conventional shape to accommodate the heating element for'the sole plate. By way of illustration I show the heating element consisting of a coiled resistance wire l2 embedded in insulating material I3 and insulated from the sole plate thereby.

The heating element is retained in position by a cover plate l4 secured to the sole plate as by a screw l5. Additional plates [6 and H constitute a substitute for the shell usually provided in connection with sadirons.

The terminal ends of the heating, element l2 are connected in any suitable manner with terminal prongs l9 which are partially housed by a guard 25. The terminals l9 are supported by a bracket i8 resting on. the cover plate M. The bracket I8 is positioned relative to the cover plate It by openings l6a and He in the plates l6 and I1. The usual iron cord plug (not shown) is adapted to be associated with the terminals I9 for conducting electricity to the beating element of the iron.

The additional plate i6 is provided with three downwardly projecting formations 2| which serve to space'the plate It from the plate It. Screws 20 extend through perforations in the plate l1 and in the formations 2| and into the sole plate S for retaining the plates l6 and I1 assembled relative to the sole plate.

The plates l6 and l'l are spaced from each other by formations 22 (see Figure 3) on the plate l6. Rivets 23 extend through these formations and through the plate I! for retaining the plates l6 and I1 assembled as a unit relative to each other. The spacing means between the plates l4, l6 and I1 provides for air circulation between the plates thus effectively dissipating heat from the sole plate to atmosphere and resulting in reduction of the radiation of the heating from the sole plate to the hand of the user during use of the sadiron.

' The sole plate S has at its front end upwardly projecting flanges 26 which serve as a guard over the front ends of plates I6 and H to eliminate the possibility of fabrics being ironed catching thereon.

The handle H comprises a pair of handle elements 2! normally alined with each other by tongues 28 and grooves 29. Rod elements 33 extend from the ends' of the handle H downwardly toward the sole plate S. The terminal ends 3| thereof are received in semi-socket like projections or formations 32 formed in the outer most or upper plate I'I.

The terminal ends 3| of the rod 33 are pivoted so that the handle elements 21 can be separated and the handle swung down against the sadiron as disclosed and claimed in my patent above referred to.

The relatively flat character of the sole plate S and its cover means IE, IS and I1 is a feature which contributes to compactness of the iron when folded. Due to the space between the plates however, heat is readily dissipated and excessive radiation to the handle H is thereby eliminated. As the iron is passed over the fabric being ironed, the air circulated over the platesheat is reflected toward the ironing surface of the sole plate by the cover plate I4 which is preferably polished on its lower surface to aid in its heat reflecting properties. Dissipation of the shown in Figure 4 are located in these spaces,

the dissipation of heat at this point is also facilitated. It is thereforeobvious that I have provided a relatively fiat cover means which approaches in emciency the heat dissipating quality of a relatively thick hollow shell.

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 of structure or use of mechanical equivalents, which may be reasonably included within their scope.
