Z P/ Patented Dee. 24, 1935 UNITED STATES PATENT OFFICE My invention relates to pressing irons and particularly to an iron of this character which utiwith an iron heated by electricity, gas, or other fuel, or which depends upon thesteam alone for its heat.

The principal purpose of the invention is to provide in a device of this character a. novel means for super-heating the steam from the iron heating element.

heating path and thence to a baflie before the steam is passed out through the face of the iron.

My invention contemplates also the provision, in a device of this character, of the above mentioned features while maintaining the steam conalso that the heating element may be readily replaced without disturbing the steam passage so as to cause any leakage.

It is a further purpose of my invention to provide in a pressing iron a novel construction of the to get the edge of the iron underneath buttons, pleats, and the like.

I will describe the preferred form of my invention by reference to the accompanying drawings wherein-- Fig. 1 is an exploded view of the iron base showing the three elements which go to form the steam passages separated so that the structure may be readily understood;

Fig. 2 is a longitudinal section through the iron taken on a vertical plane; and

Fig. 3 is a fragmentary plan view of the nose of the iron. I

Referring now in detail to the drawings, a pressing iron of this type is made up of a base plate 5 which has suitable openings such as shown at 6 and 1 for the passage 01' steam from the steam duct or conduit 8 to the pressing face of the iron.

In this device the heating element which is a well known structure is shown at 9 as overlying the base portion of the iron and it is held down by the weight or plate in which is in turn clamped to the base portion by means of the bolts II and I2 which pass through a. suitable slot running longitudinally of the heating element 9. This slot preferably is long enough so that both bolts pass through the same opening.

The bolt [2 has the reduced extension I5 upon which the housing I6 is secured by means of the nut I! in a well known fashion. This housing It 6 fits down over the shoulder l8 on top of the base 5 so as to enclose the heating element.

The

' The heating element terminals are carried out as illustrated at 2| and the handle portion 20 carries a suitable guard 22 through which the cord socket is passed to engage the terminals 2|.

The above description outlines the general structure of the iron and I will now describe the base portion which provides the novel steam super-heating and spreading means.

Referring now to Fig. 1, the base is made up of the main base portion 5, an intermediate plate 23 and a closure plate 24. In the base 5 I provide the outer groove 25 into which the openings 6 finally passes in being delivered to the openings 25 6 and I.

Immediately inside the channel or groove 25,

I provide the barrier or baiiie wall 26 which is cut out as indicated at 21 to provide ports leading from the spreader chamber 28 to the distributing channel 25. The plate 23, the bottom of which is flat and completely closed except for the opening at 30 in the center thereof fits within the flange 29 which provides the shoulder I8 and rests flatly upon the top of the barrier 26. The opening 30 discharges the steam down into the chamber 28 substantially centrally of the space surrounded by the spreaders 3| (see Fig. 1).

Thus the steam passing through the opening 30 is spread outwardly in the chamber 28 and must rise over the baffle walls through the ports 21. The chamber 28 thus, in effect, forms both a central spreading chamber and a water trap for catching any water that may condense, for hold- 4r ing the water until the heat of the iron evaporates it. The plate 23 is sealed steam tight in position to the flange 29 as by welding, brazing, or otherwise. This plate 26 has the longitudinal tortuous groove 33 in the top thereof which 5 groove leads from the inlet projection 32 to which the steam fixture 34 is connected around the plate 23 substantially twice before arriving at the opening 30. The barrier wall 35 is thickened at 35 to provide mounting for the bolt II, and the 2 lug 31 provides a body for screwing the bolt l2 ing pins 4|, 4| and 42. This plate is then welded further insure a delivery or sealed in position in any suitable manner so as to transform the groove 33 into an air or steam tight passage connected by the opening 43 to the steam inlet at 32. Plate 24 and the top surface of the outer rim of the grooved plate 23 as well as the top surface of the barrier 35 are all directly against the bottom of the heating element 9 so that the elongated passage formed in the plate 23 serves as a super-heating conduit for the steam introduced into the iron. This steam approaches the interior of the iron as it moves around the groove 33 and is heated upso that its maximum heat is reached so far as the super-heating conduit is concerned at the time it passes through the opening 30.

It is believed to be evident from the foregoing description that I have provided a novel base structure which effects a. super-heating of the steam without any danger whatsoever of leakage back to the heating element. It is also evident that the distribution and trapping features will of dry steam through the openings 6 and 1 to the face of the iron with substantially uniform pressure. Another feature of this iron is found in the base Sin the shaping of the edges and corners.

Referring to Figs. 1 and 2, it will be noted that the three corners of the base arenonvex in contour as indicated at 45, 46 and 41. These corners rise rather abruptly, in fact almost at right angles from the pressing face of the iron so as to prevent their sticking under wrinkles in the material and tearing the material. Immediately back from the corners however, the side edges of the base plate 5 are curved inwardly to provide concave surfaces 43, 49 and 50 joining the lower edge by means of a convex portion 5| ofvery shortradius so that the side edges of the iron may be assed underneath buttons, pleats and the like and thus more completely finish the pressing of the garments.

From the above description it is believed that the construction and advantages of this device will be cleared to those skilled in this art. It is also believed to be obvious that various modiflcations may be made from the exact details shown and described without departing from the scope of the invention as set forth in the objects and defined in the claims.

Having thus described one specific form of my invention what I claim as new and desire to secure by Letters Patent is: I
