(Cl. 38-417) v sembly and operation, and many of its advan- 4 Claims.

This invention relates generally to electric sadirons and more particularly to a sadiron adapted to be used either in connection with steam producing means whereby the steam may be extravasated through the sole of the sadiron as in pressing or steaming apparel and the like, or in the conventional dry pressing methods.

A primary object of this invention is to provide a novel construction for an electrically heated sadiron adapted to be used in connection with a steam generator supplying steam thereto during the pressing or steaming operations;

A further object of this invention is to provide a sadiron of the character described which will be immediately convertible from a steaming iron to a conventional dry pressing iron and vice versa.

A further object of this invention is to provide a combination of steam generating means adapted to feed a sadiron which will be small in size, eflicient in operation and adapted for portable household use.

Further objects of the invention lie in the provision of novel means for heating or superheating the steam which is delivered through the sadiron and removing moisture therefrom; novel means for maintaining the high temperature of the front'apex of the sadiron; novel and simple construction of the sadironfto assure efficient operation thereof; novel means for preventing the inclusion of moisture within the steam delivered by the steam unit.

An important object of this invention is to provide apparatus of the character described which will be'simple in construction, efficient and economical in operation, and which will be adaptable for low-cost production in large quantities.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel features of construction, arrangement and combination of parts hereinafter fully described, illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

For-the purpose of facilitating an understanding of my invention, I have illustrated in the accompanying drawing a preferred embodiment thereof, from an inspection of which, when considered in connection with the following description, my invention, its mode of construction, as-

tages should be readily understood and appreciated.

Referring to the drawing in which the same characters of reference are employed to indicate corresponding or similar parts throughout the several figures of the drawing:

Fig. 1 is a perspective view of an embodiment of my invention in use andshowing the steam generating unit associated with a conventional ironing board, the sadiron, and the connecting cable. I

Fig. 2 is a longitudinal sectional view of the sadiron taken through the superheating chamber.

Fig. 3 is a detailed plan view of the trout portion of the iron with portions thereof in section showing the front steam chamber.

Fig. 4 is a sectional view of a detail of the sadiron taken generally along the line of Fig. 2.

Generally speaking, the invention consists'of an improved construction for an electrically heated sadiron having a novel connection with a separately maintained steam generator whereby steam may be generated in large quantities and at suitable temperatures within the steam generator under favorable conditions and conducted to the sadiron for use therein. I provide means whereby the sadiron may be used without the steam in the manner of conventional sadirons. Further, I provide the steam generator with novel means whereby it may be conveniently attached to an ironing board or the like, in any manner, for advantageous usein connection with my sadiron.

Figure 1 shows the arrangement oi! the apparatus of my invention in use. The reference character ill designates generally an ironing board of any conventional type having the steam generator i2 clamped thereto bymeans of the clamping member it which is attached to the upper wall of the generator it. Obviously any horizontally disposed support such as for example a table or the seat of a chair may be used to support the generator. Further, where necessity requires, the clamp may be adjustable so that the generator may be attached for use to an upright support such as the back of a chair and the like.

The sadiron is generally designated by the reference character it and it is connected to the steam generator it by means of a cable or sheath ll which will be presently described in detail. Thecable it passes through the eye end oil a support member 9 which may be secured to the steam generator E2 or directly connected to the supporting board 90'. Ihe support member 9 may take any convenient form, the type shown being for illustrative purposes only.

The sadiron it may be practically any conventional construction, it being noted that I require only slight modification over models presently manufactured-and sold commercially. A sole plate M is provided having the usual pointed front end or apex and having a casing disposed thereon supporting a handle it secured thereto in any well known manner, such as for example by welding or the like. Forwardly disposed of the base plate id are a plurality of steam ports IQ for discharging the steam from the sadiron upon the work which is being pressed. The upper ends of the ports l9 open up to a substantially triangularly shaped steam recess ll formed in the upper surface 'of the plate M and completely enclosed by means of a conformingly shaped plate member it secured to the plate it directly over the recess ill by screws or the like.

The plate member 58 is provided centrally thereof with an upstanding boss 20 by means of l which steam may be led into the recess H. The

ports 59 are distributed about the floor of the recess li away from the'point where steam which is discharged through the boss 29, in a manner presently to be described, will impinge. Thus, it is seen that the single stream of steam dischargedinto the recess ill will be broken up and distributed to the openings leading to the ports l9 and subsequently be extravasated in uniform and efficient. manner.

Immediately disposed upon the upper surface of the plate member M and substantially covering the entire extent thereof I have provided a heating element 22 of any'convenient construction such as for example having upper and lower sheets 23 of insulating material such as mica or asbestos and a cover plate 26. The element is secured to the plate in any well known manner. In order to assure even heating of the entire sole plate it! and. especially to provide for the heating of the extreme front end of the sadiron, i utilize a heating element having a notch or opening 24! therein at the extreme front end thereof which extends over the plate member it of the recess W and permits the boss 2i to extend therethrough. While I have shown the opening as a notch, it is obvious that it could as well be a hole in the element 22 through which the boss 20 is adapted'to extend thus permitting portions of the heating element to extend to the geometrical tip of the inner surface of the sole plate it. I have found, however, that the arrangement shown in the drawing gives satisfactory results.

It should be obvious from the above explanation that the upper edge of the plate member 88 should be either flush with or below the surface of the plate member id in order to assure correct lying and positioning of the heating element. The arrangement described places portions of the heating element in very close proxid of the sadiron to one side of the thermostat 32 as shown in Fig. 4. The receptacle is disposed upon the heating element 22 upon the upper plate 2% thereof and hence, is subject to the highest temperatures generated by said element. Thus, steam which may enter the chambers of the receptacle will be heated to high temperatures and will have any moisture contained therein removed and vaporized. The receptacle in efiect serves as a superheater.

The receptacle 25 is divided into a front charm ber and rear -chamber bymeans of the partition or wall 26 separating and dividing the interior thereof. The conduit it enters the front chamber and steam contained therein may pass Ihe ends of the tubes 2i and 29 which are disimlty to the recess or chamber ll into which the steam is finally discharged prior to extravasation through the ports is. Thus the steam loses ;none of its heat by being discharged into the chamber 91, but on the contrary, takes on heat which aids in the emciency of operation of the sadiron. The recess in efiect serves as a heater.

The boss 20 is provided with a conduit 2i attached thereto which conduit leads to a bi-chambered receptacle disposed within the casing operator.

posed within the respective chambers of the receptacle may or may not be open since the steam will be permitted to pass by means of the laterally disposed openings 27! and 3%. However, I prefer to have the ends open.

It will be seen that the steam which enters the receptacle from the steam generator will circulate therein and be superheated by reason of the proximity of the heating unit 22, will then pass through the perforations as of the baifle or wall 25 and into the front chamber of the receptacle. Thence the steam will pass into the conduit or tube 2i and finally out through the ports 89.

The sadiron it is provided with a thermostat 32 of any suitable construction adjustable by means of a pivoted knob tidextendingout from the upper wall of the casing E5 in convenient disposition adjacent the hand and fingers of the Obviously the thermostat controls the iron temperature. The thermostat 32'and heating element 2'2 are electrically associated in a well known manner and have electrical leads 3? and 36 leading to an external connection or plug 35 disposed upon the casing i5 at the rear thereof. A rearward extension 3! of the casing is utilized in well known manner to stand the iron on its heel when same is not being used or when the sadiron is being used to steam hats or the like.'

It will be noted from the above description that the steam is brought to the sadiron it from outside sources. Hence, the iron can be made smaller and lighter and need not be provided with means for carrying water and the like. Further, since the steam source is not carried upon the sadiron, said source may be relatively larger than the steam chambers of steam sadirons heretofore used and thus make steam available a much longer time without the necessity of stopping to fill the liquid chamber. p

The sheath or cable H is a unitary construction and may be formed from flexible fabric, rubber and the like. It is provided therein with a steam conduit and the electrical leads which con The advantages of this single cable construction should be apparent.

The electrically heated generator H which I have illustrated is provided with a filling mechaobjects ot'the invention have been attained'in a. novel and emcient manner.

Thus, the iron may be used as any conventional iron and without steam, it being obvious that heat control is possible by means of the thermostat 82.

It will be apparent from the above that the It is believed that my invention, its mode of -construction and assembly, and many of its advantagesshould be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention as de- ,flned in the appended claims.
