This invention relates generally to pressing irons, and more particularly to pressing irons of the type having a self-contained steam generator for discharge upon the material being pressed during the ironing operation.
Among the objects of the present invention lies the provision of a steam iron which is convenient and foolproof in operation, requiring no special skill in the use thereof and which is completely safe.
Steam irons as such have been known in the prior art and they have been' open to a number of serious disadvantages. vantages is the fact that in certain constructions, when the steam pressure in the iron rises to within certain limits, the steam forming chamber is subject to bursting. Anotherdisadvantage in priorconstructions lies in the fact that, many of such devices in use discharge very wet steam and quantities of water. This wet steam or hot water has an extremely deleterious eflect on certain fabrics such as silk or rayon, and especially those of a thermoplastic nature such as those woven of cellulose acetate fibres. With this loss of water, the consumption of the water within the steam forming chamber or other reservoir is increased so that the need for refilling the chamber with water becomes more frequent. Another disadvantage of prior constructions lies in the fact that the iron itself is in the form of or has associated therewith a tank or other reservoir for the containing of water. Access to this tank or reservoir is gained by means of a small port closed by a threaded plug. Since the leakage of steam through this-port lowers the efliciency of the iron, it is customary to provide the plug with a gasket and toturn the same into its seat tightly. Owing to the expansion or contraction of the metal bordering the port or in the plug, as the case may be, the plug frequently becomes tightly wedged or frozen in place, requiring special tools to remove the same. Also by reason of the small size of the port and by reason of the fact that the inside of the water tank or res:- ervoir is invisible, it becomes necessary to use a funnel and to pour in through the port by means of the funnel, a certain predetermined amount of water, previously measured. a
It is, therefore, an object of the present invention to providean iron incorporating a novelfilling structure, thereby avoiding the-disadvantages just described. "In accordance with the present invention, the filling of the iron with liquid'to the proper level requires only a simple dipping motionand does not require the movement of any valves or ports on the iron" itself;
Another object .herein lies in the provision of steam iron structure which by reason of the sim- Among these disadpli-city in the organization thereof, permits oi large scale production at low cost, with a consequent wide use.
Another object herein lies in the provision of steam iron structure in which the steam carrying tube serves also to integrate certain of the parts of which the iron iscomposed.
Another object herein lies in the provision of steam iron structure particularly adapted to prevent the emission from the iron of any wet steam or drops of water, a fault'commonlyreferred to as spitting. I
- A feature of the invention lies in the fact that substantially a complete dismantling of the important functional parts of the iron may be accomplished by removing two screws. 'Thispe'rmits of low cost manufacture and convenient and low cost servicing.
.Another object herein lies in the provision of a steam iron in which the heating areaof the sole plate is increased so as to be practically equal to the heating area of the sole plate of irons lacking the steam producing feature.
Another object herein lies in the provision of structure of the class described wherein the water tank or container is so organized with relation to the iron body that a-great deal of the cubic capacity of the body is utilized for the storage of water and the generation of steam. This results in only a short interval of idle time during which the iron raises the water to the boiling point, and it also results in a lower overall height I so that the iron is more convenient in use and presents a more desirable streamlined appearance.
Another obiect'herein lies in the provision of structure for the conducting of steam from the steam forming chamber to the outlet in the sole plate in such a manner as to reduce the tendency of the steam entering the tube to carry with In accordance with the present invention, the splashing of water within the body of the iron upon the entrance to the passage for the steam being emitted, is reduced to a minimum. These objects and other incidental ends and advantages will more fully appear in the progress of this disclosure and be pointed out in the appended claims.

Ill
I a well known manner.
The assembly or disassembly of the device I0 is a relatively simple matter, and by way of example, one method of assembling said device is here given. The second body element I 3 is taken and the upper end of the conduit 2| is screwed into the threaded bore 69. Next, the screen 20 is slipped over the lower end ofthe -conduit 2|- and is pushed into its seat in the lower annular groove 1|.
The contact pins 29 are attached to the bottom well portion 49 by means of insulated bushings in With the spring I01 and the washer I08 thereon, the thermostat is put in place with the spindle I04 penetrating the necks 50 and 81, the gasket I09 having previously been cemented to one of the said necks.
The heating element 24 is connected to the thermostat 21 and the contacts 26 by conductors in a well known manner, not shown, which penetrate the gasket I I0.
The gasket I08 is laid in place and the body element I2 is placed over the conduit 2|, the said conduit penetrating the conduit carrying tube 55.
The gasket 0 is put into place and the bolt 25 is passed through the lower portion of the bracket I5, the rear wall 65, the gasket I08, the
retainer bolt carrying tube 56, and the gasket I I0.
The sole plate 23 is now put in place and is secured thereat by rotatingthe bolt 25 and by placing the gasket IN and the head 22 upon the lower end of the conduit 2| and tightening the same. the thread in the portion 81 co-acting with the threads on the lower end of the conduit 2|. The tightening of the head is accomplished by means of a special wrench previously described, while an ordinary screwdriver may rotate the bolt 25. When the head 22 is in its fully seated position, the lower surface 91 thereof-is coplanar with the lower surface of the sole plate 23.
Next, the handle I4 is put in place by placing the front portion 13 upon the shank portion 9|.
The bolt I6 is next passed through theportion II of the bracket II, the bore I! and finally is screwed into the-shank portion II. The handle I may now be put in place.

Operation The operation of the device III is preferably as follows. The electrical contact plug I2. is connected to a suitable source of current and placed upon the pins 28 in a well known manner. The iron is allowed to heat to a temperature substantially above the boiling point of water. The
filler stand H2 is filled with cold water. The device I0 in its heated condition is placed in the filler stand. The contact of the water in the stand with the sole plate and the first body element, cools the same, causing a contraction of the air. therewithin, which had been previously expanded when the iron was heated. The contraction of the air causesa vacuum within the principal steam chamber of the iron and sucks in the water from the filler stand. This sucking will continue until the water in the filler stand drops below the level of the opening around the edge of the lower surface 91 of the head 22. Depending upon the level of the surface I22 or the adjustment in height of the legs H8 and III, the entire or substantially-the entire contents of the filler stand will be sucked into the iron IO. The iron may be removed from the filler stand and placed upon its heel or may be allowed to remain in the stand. In a relatively short time, the water within the iron will be raised to the boiling temperature and steam from said iron will pass upwardly through the screen 20 through the 01-1-- ing movement with the pressing surface 80 in contact with the material being treated, splashing of the water within the steam chamber formed by the first and second body elements is inhibited by means of the baiile l2 and any splashed water is prevented from entering the steam .carrying conduit 2 I by the screen 20 and the nipples 8!.

The iron, thus in a steam emitting condition, may be used in a usual manner. As the iron is moved back and forth in the pressing movement.
with the pressing surface 88' in contact with the material being treated, splashing of the water within the steam chamber l8 formed by the first and second body elements is inhibited by means of the bailie l2 and any splashed water is prevented from entering the steam carrying conduit 2| by reason of the placement of the orifice l2 and the trapping action of the chamber ll.
It may be noted here that as best seen in Figure 6, the water chambers extends rearwardly of the contact pins 26' so that the heel space normally wasted in prior constructions is utilized for carrying water. It may also be noted that the forwardmost portion of the heating element 24' is positioned-in advance of' the steam emitting circular orifice II.
The structure of the iron is particularly adapted for operation in the manner describedhereinabove by reaso of-the fact that the lower portions of the n are substantially hermetically sealed, except, of course, the entrances to the cal heating element therein. Also by reason of The filler stand for use with the second em- The operation of the device ,II is preferably as follows. An electrical contact plug is connected to a suitable source of current and placed upon the pins 28' in a well known manner. The
iron is allowed to heat to a temperature substantially above the boiling point of water. The
filler stand is filled with cold water. The device the fact that the contact pins 26 or 2| are disposed within a relatively deep well, the water into which the iron is dipped is prevented from shortcircuiting the contacts. c
I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
