This invention is an improvement in press .mgirons.

Anobject 'of my invention is to a pressing iron of the type having a self.- z'l contained steam generating means, whereb V a uniform flow live steam may be'appli directly to the article to be pressed.

Another object of my invention is tojconstruct asheet metal ressing iron of the above 10 named character w ich .is safe, light, sim is of construction, compact and easy to'han e.

A'further ob ect o my invention is to construct an iron for pressing which will not,

- burn or mark the articles to be pressed.

Other ob'ects and advantages of my invention wi become more apparent as-th'e' following description of one embodiment thereof progresses, reference being made to the accompanying drawings in which like reference characters are employed to desig-.

nate like parts throughout the same.

In the drawings:

'Fig. 1 is a phantom plan view of the'iron fornnng oneembodiment of my invention.

'Fig. 2is a longitudinal section taken on line 2--2 of Fig. 1.

. Fig. 3 is a transverse vertical section taken' on-line 33 of Fig. 1.

- In the form of my'invention illustrated in the accompanying drawings, 1 is the sheet metal body of the pressing iron having a sheet metal bottom plate 2 which is enga eable with the article to be pressed. A han le 3, is rovided on the upper face of the body 1 and an electric connection receiving socket 4 is provided at the rear end of the body for receiving the insulated lug 5 connected at one end of an electric ca le- 6, the cable being connected at its other end to a source of electrical energy. A terminal block- 7 of suitable insulating material such as porcelain or the like, is provided at the base of the socket 4 and carries the terminals 8 of the electrical heati g unit 9. The heating unit 9 is housed withi water proof casing 10 near the bottom face 2 ofthe iron bodfy and is electrically insulated therefrom by t e insulating material 9a. The interior 11 of the body provides 50 a suitable container for a quantity of'water,

e the interior of the body 1 into compartments 14 15 and 16 respectively, and prevent-spla ing of the water within the iron while the iron is in use. The plate 13.

is cut away as at 17, and the plate 13a is cut away as at 18, to permit the water in one compartment to, flow. into another compartment so that the water level 12 will be substantially the same in each compartment when. the iron isin a horizontalplane as indicated in Fig.- 2. The u per walls of the

plates

13 and 13a 17a and 18a, respectively, to permit the steam v to passifrom one compartment to another and to .e ualize the'steam pressures therein. Secure to the upper wall-19 of the body 1 is. a trap 20, the interior of which commumcates with the interior of the compartment 14. b

, meansof an aperture 21 formed in the w 19 of the body. The trap 20 is preferably a dome like structure and terminates in a con-' duit or tube 22.. A tra plate 21a is secured or more openings 20ato permit the steam in the lower portion of the dome to pass upwardly into the tube 22, but which revents' any passage of water into the tube. the steam passing into the tube 22 should condense-in the portion of the tube outside the iron, it will either pass back into the trap and thence to the water compartment, or down into the vertical ortion of 'the tube which passes through the. eated water within the iron, when it ma .be vaporized again beintervals extending across the bottom face 1'59 withinthe dome 20 an is provided with one I f any of '0 pression of a spr n degree by turnin desired. The valve 26 ma be operated to cut off the flow of steam bot through the port 2611. and through the conduit 22 and ducts 23 simultaneousl or if desired it may be operated to eject-a jet of steam throu h the port 26a alone onto an article place near the said port. In this manner steam from the interior of the iron may be directed through the valve and port directly onto an article to be steamed, such as a hat. In Fig. 3 I have shown a pressure gauge 27 so communicating with the interior of the body 1 so that the 'r'essure of steam generated within the chamer, and which accumulates above the water line, may be indicated. I also rovide a safety valve 28 in which the valve ead 29 is normally seated on a valve seat 30 by the com- 31". The compression of e adjusted to the desired the cap 32 which is screw threaded over the dy 33. The valve body 33 is threaded at 33a permitting it to be screwed into the falling opening 40. Shoulders 41 are formedon the body 33 to permit the opthe spring 31 may erator to readil screw the valve into the ing'limit',

enough to permit the openin 40, wit out disturbing the adjustment 0 the valve. If the steam pressure in the intefior of the iron exceeds a'safe operatthe safety valve 28 will be actuated to release the pressure. Water may be introduced into the body of the iron through .the filling o ening 40 by removing valve 28 therefrom. water gage is provided to indicate the level of the water within the iron.

In use, the embodiment of my invention illustrated in the accompanying drawings operates as follows:

When the connector 4 is connected with the terminals 8 as shown in Fig. 2 and electric current is sup lied to the heating unit 9 the temperature 0 the water will be raised graduall to a point suflicient to generate steam whi e the bottom plate 2 will become hot iron to be used for pressing articles. Steam thus generated within the body 1 will be communica ed through the opening 21 into the trap passing through the openings 20:]. 0 plate 21a and thence into the tube 22, where it is communicated to the ducts 23 extending transversely of the iron. This steam will then be ejected in the form of jets through the openings 25 to the article over which t e iron is passed during the pressing operation, thus eliminating the application of steam by 20, the

" hand or from anexterior source of supply up er part of said ba said pipe,

during the pressing operation. In the operation of my invention it is desirable to maintain the water level above the heating element shown at 10 in Figs. 2 and 3. v A

, -It will be seen that Ihave constructed a pressing iron which is extremely simple in construction, light, safe,' easy to handle, compact, and which is extremely eflicient in operation.

It will be seen that I have constructed a pressing iron constructed preferably of sheet metal and having a self-contained steam generating and distributing means, permitting the iron to be used for pressing without danger of burning the articles to be pressed, by projecting steam upon the articles while the iron is in contact with the articles to be pressed. This condition will exist as long as steam' is ejected onto the articles through the openings 25.

An iron constructed in accordance with this invention may be safely operated over a considerable period without replenishing the water supply. However, the water level should not be allowed to go below the heating unit and for this reason I have provided the gauge 50. Itwill be noted that the heating unit is plate 2 eing nearlyl entirely surrounded by the water within t e iron. It will also be noted that by my invention I am enabled to supply a constant flow of steam on to the articles to be ressed, and that the flow may be controlled by the 3-way valve 26.

Having thus described one embodiment of my invention so that others skilled in the art may readily practice the same, what I claim and desire to secure by is defined in the following claims:

1. In a self contained steam generating pressing iron, in combination, a water reservoir, a steam dome thereabove, a steam pipe leadin from said dometo the pressing face of sai iron, and bafiles in said reservoir and said dome to prevent passage of water into said pipe.

2.

3. Means for steaming and pressing fabrics comprising a boiler, a pressing face constituting the bottom of said boiler, a steam delivery pipe from. said boiler, a steam connection from said pipe to said pressin face, an outlet from said pipe above said boiler, and a valve having a plurality of outlets in one of said outlets having a conduit extending to said pressing face, another preferably located near the presser Letters Patent of said outlets communic mosphere,
