ElEgllfl-HEATED IRON.

Application filed September 22, 1926. Serial No. 187,052.

This invention relates to an improved steam heated iron of the type used by tailors and the like employed for supplying mois; ture to the apparel while being pressed.

Briefly. the improved structure comprises ahollow body constructed to provide amain steam chamber through which steam is circulated. together with a special compartment or auxiliary chamber into which a separate supply of steam is injected to moisten the article being acted on. Y

My primary aim isto generally improve upon steam-heated irons of this class by providing one of comparative simplicity and durability which is further characterized by such features as ease of machining and manufacturing, low costof production, and efliciency in operation.

Other features and advantages will become apparent from the following description and drawing. In the drawing: I

Figure 1 is-a view in section and elevation showing the improved construction and arrangement of parts,

Fig. 2 is a bottom plan view of the same with portions broken away to disclose certain of the details more plainly.

Referring to the drawings in detail, it will be seen that the reference character 1 designates a single metal casting of customary external configuration. By the term cusexternal configuration, I mean a body which is of substantially semi-ovate outline. and which includes smooth substantially flat bottom surrounded by a marginal upstanding rim. The casting is formed into a hollow body which is open at its top and provided at said top with an inwardly extending flange 2. The bottom 3. which is flat for a considerable-portion of its area. is

formed with an integral inwardly extending conical portion pending bos es 5 disposed at diametrically opposite points. A removable closure forming disk 6 is secured to these bosses by fastening screws 7' and this disk is provided with annular rows of circumferentially spaced steam central portion of the disk is substantially imperforate. The disk cooperates with the cone in providing a special steam chamber for supplying moisture to the cloth being acted upon. Connected to the apex of the cone is an individual steam-supply pipe 9.

A removable cover or top plate 10 is fas- 4. The cone includes de-' discharge apertures 8. Thetened as at 11 to the flange 2 and suitable packing is interposed between the parts toprovide a steam pipe joint. This cover is provided with upstanding standards 12 upon which a hand grip 13- is mounted-.- A main steam chamber circulating is thus formed around the conical steam chamber. A separate steam. supply pipe 14 extends into tl1is.main steam chamber and a discharge pipe 15 is also located therein. The discharge end of the pipe 14 is located in prox: imity to the base portion of the cone 4:. The intake end of the discharge pipe 15 is located atits remote point. The pipe 15 extends as at 16 on the exterior of the iron to a suitable source of discharge. A suitable main steam supply pipe is indicated at 17 and this connects with branches 18 and 19 on a special fitting, each branch being provided wlth a valve 20 and 21 respectively.

With the arrangement shown it is obvious that the steam supply passing through 011'. pipe 17 may be simultaneously injected into the main chamber and the auxiliary conical chamber when the valves 20 and 21 are open. However, the supply of steam may be divided by closing the valve 21 for instance to keep the cloth substantially dry while heating the body of the iron to a degree sufiicient to accomplish eflicient pressing.

A particular advantage to be borne in mind in connection with the improved construction is that the respective steam chambers are entirely separate and independent from each other and since the steam is supplied to the main chamber substantially continuously while the iron is in use, it is obvious that a considerable amount of moisture will collect in this chamber. Inasmuch as it has no communication with the auxiliary moistening chamber, however, it is obvious that rust and dirt accumulation can not enter the small chamber and pass into and discolor the cloth. This-scale and other extraneous matter which de osits in the main chamber can be removedli movable cover. It is also obvious that by having a removable plate for the conical chamber, any rust dep'csit may be separately removed therefrom.

It is believed that by considering the description in connection with the drawings, a clear understanding of advantages and construction of the improved iron will be.

had. and therefore, a more lengthy description is thought unnecessary.

y way of the remamas Minor changes comin within the field of invention claimed sired.

In a steam heated iron, a casting comprising a semi-ovate fiat bottom surrounded by an upstanding marginal rim defining a main steam circulating and heating chamber, said chamber being open at its top, a cover plate for the open top detachably seated on the rim, said plate being provided with 11 standing standards, a hand-grip carried y said having an inwardly may 7 resorted to if destandard said bottom projecting hollow cone forming a .supple-. mental moistening cha 1 am removably mounted apertured closuredisli forming the base of the cone, a plurality, of valved steam supply pipes, one of said pipes being in com munication with the interior of the cone, and one with the interior of the main chamher, and a steam discharge pipe leading from the said main chamber.

In testimony whereof I afiix my signature.
