Application March 13, 1941, SerialNo'. 383,091

9 Claims.

My invention relates toi'mprovements in an electric pressing iron, and particularly to the type adapted to discharge steam upon material during pressing. v 1

Many improvements have been made'in the construction of such pressing irons, some of which embrace generating the steam within the iron, while others embrace means for controlling the humidity or moisture content of steam supplied to the iron from a remote source.

My earlier United States Letters Patent Number 1,799,281, issued April '7, 1931, and entitled Flatiron and my co-pendirig United States application SerialNumber 176,000 filed November 23, 1937, now Patent No. 2,241,945, and entitled Laundry pressing iron have reference to improvements in the construction of irons of the latter designated type. a

My present invention also has particular reference to further improvements in the concontent of steam supplied to the iron from a remote source before the same is discharged from the iron onto the material being pressed.

Accordingly, my present invention has for its principal object the provision of an improved relationship for the instrumentalities associated with the steam conduits within the pressing iron.

Another object of my invention is to provide an improved condensation or moisture trap in the steam conduit within the iron.

' A furtherobject of my invention is to provide a moisture trap comprising a metallic cup filled with absorbing material of low heat conductivity, preferably a bestos wool, upon which the live steam is discharged within the iron.

A further object of my invention is to provide a super-heating chamber adjacent the heating element in the sole plate, within which the moisture trap is disposed for providing an effective conversion of the untreated steam and all free moisture into a uniform steam having the re-' quired humidity.

Another object of my invention is to provide instrumentalities for treating steam supplied to the iron that are simple in construction and easily replaceable.

The advantages of these and other objects will manifest themselves as the following description is read in connection with the accompanying drawing, in which Figure 1 is a side elevational view of my pressing iron shownpartially in section along line 'tramand and relation of the parts comprising the moisture Figure 2 is a .plan view of my pressing iron shown partially in section along line 22 of Figure 1 for furtherillustrating the construction and relation of the parts comprising the moisture trap. v

In the preferred embodiment of my invention illustrated in .the accompanying drawing,- the numeral l, designates a conventionalhollow shell or cover 12. ventional handle having a suitable grip, which handle is secured to and spaced from the sole plate I and shell l2 by means of vertical supports l4 and I5.

It is to be understood that the sole plate I of my pressing iron is heated by means of a suitable electric heating element 20. Generally, the heating element 20 comprises a conventional triangular shaped heating element disposed in a suitable plate above the chamber containing the moisture trap.

Accordingly, it is to be understood that the steam conduit II], which enters at the rear of the iron and near the base of the shell I2, extends along the top face of the sole plate and substantially adjacent the electric heating element 20, as illustrated in dotted lines inFigures 1 and 2. Near the forward end of the sole plate, the conduit I0 is arched upwardly so as to extend over the electric heating element and operatively connect a conduit 9, which conduit communicates with the central portion of a circular chamber Therefore, steam from a remote source enters conduit 10 at H and is directedinto the chamber" via conduit 9. Obviously, the untreated steam entering the conduit NJ at II is superremain in a liquid state. Therefore, I have provided a moisture trap onto which the steam is discharged before the same is discharged from the iron.

l-I of Figure 2 for illustrating the construction With reference to Figures 1 and 2, it-will be The numeral 13 designates a conobserved that the numeral I designates an annular cup removably secured in the chamber it by means of suitable threads. As illustrated in Figure 1, the lower portion of the cup I is provided with annular rows 'of perforations l, and

the outer face of the cup is adapted to form a smooth and continuous surface with the pressing face of the sole plate i.

wool of the-moisture trap. It is also important to observe that the lower face of the sheet metal cup is provided with a series of oifset portions 6 for spacing the lower face of cup 5 from the perforated face of cup 2. Similarly, with reference to Figure 2, it will be observed that a series of vertical grooves l6 are formed in the vertical walls of the annular cup 2, which grooves communicate with the space between the lower face of cup 5' and the perforated face of cup 2, and

with the chamber ll.

, Accordingly, it will be apparent that the steam discharged upon the moisture trap enters the same through the central opening in the wire mesh guard, whereupon the steam passes through the asbestos wool and escapes through the wire mesh guard, and, via grooves ii and the space between the faces of

cups

2 and 5, the steam is discharged from the chamber it via grooves i6 and perforations 3.

It will be apparent that all free moisture or globules of water are removed from the steam as it is discharged onto the'moisture trap, and as the steam passes upwardly through the asbestos wool.

Obviously, by reason of the proximity of the heating element to the moisture trap, all captured moisture and water globules are converted into dry steam which dry steam rises and mixes with the dry steam discharged from the chamber i8.

With further reference to Figure 2, it will be observed that I have also provided three additional chambers i'l within the sole plate i, which chambers communicate with the annular chamber it. To provide for the discharge ofsteam from the chambers H, the sole plate i is provided with perforations 4 communicating with the respective chambers.
