4 Claims.

This invention relates to an electrically heated steam iron for use in ironing clothes, pressing washed goods and for other similar purposes.

Among the objects of this invention is to provide a construction that will stop water in the iron from entering the steam chamber adjacent the steam receiving pipe so as to prevent water from passing out the discharge openings. An-

' otherobject is to create an electrically heated steam iron having a steam expansion chamber adjacent the discharge openings,A and to provide in combination therewith enlarged openings for the passage of an increased supply of wet steam. My invention also contemplates such other objects, dvantages and capabilities as will later more ully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred form of my invention, yet I wish it understood that the same is susceptible of modification and 4change without departing from the spirit of my invention.

Referring to the drawing, Fig. 1 is a side elevational view of my iron with portions broken away to show the interior; Fig. 2 is a top plan view with the handle plate removed; Fig. 3 is a rear elevational view with a portion broken away as shown on line 33 of Fig. 1; Fig. 4 is a bottom plan view of the shoe plate; Fig. 5 is a, plan view of the inner surface of the shoe plate; Fig. 6 is an enlarged detail sectional view of the expansion chamber as shown on line 6-6 of Fig. 1.

The embodiment selected to illustrate my invention comprises a shoe plate I0 having a smooth outer bottom ironing or pressing surface II and a body member I2 attached to said shoe plate III by suitable means such as screws I3. The bottom of the body member I2 has a slight depression I4 to which is attached an electrical element I5. 40 A corresponding depression I6 is also provided in the inner and upper portion of the shoe plate I0 to accommodate the electrical element I5 when ticle body member I 2 is attached to the shoe plate The body member I2 is hollow so as to provide a water chamber I1. At the upper front portion of the interior of the body member I2 is a steam chamber I8 extending from about the middle upper portion of the body member I2 forwardly under the dome portion I9. 'I'he rear wall 20 of the steam chamber I8 has an opening 2| to receive steam rising from the water chamber I1.

The floor of the steam chamber I8 has an aperture 36.

55 The outer top 22 of the body member I2 has a recess 23 with an indented flange 24 to receive the handle plate 25. Screws 26 attach the handle plate 25 to the flange 24. A handle 21 is attached to the handle plate 25.

In steam chamber I8 immediately forward of I opening 36 is a substantially semicircular baille member 54 extending across the width of the steam chamber, with its inner curved surface facing the rear wall 20. `'I'he lower end of the baille member 54 contacts the floor 35 of steam cham- 10 ber I8 but the upper end of the baille member does not contact the bottom ofthe handle plate 25, thereby leaving a steam passageway therebetween. The upper end oi the baille member 54 is directly above opening 36 in the floor 35. 'Ihe 15 baille member 54 thus forms an anteroom 56 in the steam chamber I8.

In use when water, because of boiling, sloshing or otherwise, enters the anteroom 56, it strikes the inner surface of the baille member 54 and is 20 thrown by a somersault movement caused by the curve of 'the baille member out of the anteroom through opening 2l in the rear wall 20 back into the water chamber I1. Water that does not reach opening 2I in the rear wall will drop out through 25 opening 36 in the floor 35.

The baille member 54 does not interfere with the passage of the superheated steam because the steam passes through pasageway 55 into the forward part of the steam chamber I8. /30

It will be notedl that steam chamber I8 continues under dome portion I9, where it passes up into the top opening of a steam receiving pipe 31 which passes diagonally downwardly through an opening 38 in the front bottom portion of the 35 body member I2 The steam conduit 31 discharges the steam into an expansion chamber 51 formed by a recess 58 in the shoe vplate II). A modification of my expansion chamber is to provide for a communicat- 0 ing cut-out portion 59 in the lower bottom surface of the toe of the body member I2, the 'cutout portion 59 forming one expansion chamberv within the recess 58. The expansion chamber 51 has a guide portion 60 leading the steam to 45 a depression 6I in the shoe plate I0 in which are located, a plurality of spaced extra large steam discharge openings 62.

Having thus described my invention, I claim:

1. An electrically heated steam iron comprising 50 a shoe plate having an outer ironing surface and steam discharge openings, a hollow body member attached to said shoe plate, an electrical element having means forl connection with an electrical source of supply, said electrical element positioned 56 between said shoe plate and said body member, said body member having a water chamber and means for the reception of water forvsaid water chamber, a steam chamber formed within said hollow body member above the water chamber, said steam chamber having an opening to receive steam formed in the water chamber, said steam chamber having a iioor and a top. a. forewardly curved substantially semi-circular baille member extending across said steam chamber andadapted by its curved surface to somersault water entering through the opening in the steam chamber back through the opening in the steam chamber to the water chamber, said baille member extending upwardly from the iioor of the steam chamber and ending short of contact with the top of the steam chamber so as to leave a space there between for the passage of steam to the upper portion of the steam chamber, a steam conduit with its upper end in the steam chamber and its -lower end communicating with said steam discharge openings in the shoe plate, and a handie attached to said body member.

2. In an electrically heated steam iron, a body member having a hollow interior providing space for a water chamber, a steam chamber positioned in said hollow interior of the body member above the water chamber, said steam chamber having an opening to receive steam formed in the water chamber, said steam chamber having a oor and a. top, a forewardly curved substantially semicircular baiiie member extending across said steam chamber and adapted by its curved surface to somersault water entering through the opening in the steam chamber back through the opening in the steam chamber to the water chamber, said baiile member extending upwardly from the iioor of the steam chamber and ending short oi' contact with the top of the steam chamber soI as to 'leave a space therebetween for the passage of steam to the upper portion of the steam chamber.

3. An electrically heated steam iron comprising a bottom member having an outer ironing surface l and a plurality of-steam discharge openings, a

body member having a water chamber, said body member attached to said bottom member, means for electrically` heating said iron and forming steam out of the water in the water chamber, a steam chamber having walls and a iioor, said steam chamber formed within said body member above said water chamber, said steam chamber havingan opening in one of its walls to receive steam formed in the water chamber, a forewardly curved substantially semi-circular baille member extending across the width of the steam chamber and adapted to stop water entering through the opening in the steam chamber from passing farther into the steam chamber and by its curved surface to return the water throughv the opening in the steam chamber back into the water chamber, said baille member extending upwardly from the oor of the steam chamber and ending short of contact with the top of the steam chamber so as to leave a passageway therebetween for the passing or steam farther into the steam chamber, and a steam conduit with its upper end in the forward portion of the steam chamber, and its lower end communicatingwith the steam, discharge openings in the ironing surface of the bottom member.
