l Application June 21, 1939, Serial No. 280,340

12 Claims.

' This invention relates to certain new and useful improvements in electric streaming irons, the peculiarities of which will be hereinafter fully described and claimed.

Thisapplication refers to improvements over my prior application on Electric streaming iron, Serial No. 265,807, filed April 3, 1939.

The main objects of my present invention are to provide means to facilitate construction and improve effectiveness of my said prior invention and have special reference first to securing the sole plate to the main body of the iron; second to means for obstructing the water splashed up from below and tending to pass through the vent hole Il in the horizontally disposed plate: third for providing an independently mounted tube in place of the casting having the passage I2 for delivering steam from above the shelf I6 to the point of the iron; fourth for means facilitating the discharge of steam through the sole plate in place of the vertical openings in the sole plate marked I in the prior application; fifth for an improved cover plate in the top bf the iron over the steam trap; and to the points of construction and function hereinafter fully described and claimed.

In the accompanying drawing on which like reference numerals indicate corresponding parts:

Fig. 1 representsa sectional view of an electric streaming iron having improvements exemplifying invention;

Fig. 2, a plan view of my iron represented in Fig. 1 with the cover plate removed; and

Fig. 2a, a detail reversed plan view of my cover plate.

Referring to the drawing, the numeral I designates a curved top and side walls forming a shell having a pointed front end 2 and a square rear end 3, having a base plate 4 to which is tted a sole plate 5 forming a smoothing iron of the usual triangular or other suitable shape. Thefront end of the sole plate has a recess 6 for receiving the steam from the Water contained in the shell abovey the base plate 4, and provided with perforations 'I' arranged near the point of the sole plate as indicated in Fig. Y1. These perforations 'I' are slantingly arranged in a circle extending from the recess 6 to a conical opening A in which is fitted a fastening screw B the head of which is set in the conical opening above the inclined perforations 'I' and is firmly screwed into the base plate 4. An upward projection 5a from the sole plate makes contact with the base plate in the center of the steam recess 6, and a similar projection 5b making contact with the end 3 at the rear of the iron, is firmly held by said screw L passing through the same as shown in Fig. 1.

Steam is delivered to the recess 6 by an inclined tube C forming the steam passage I2. The bottom end of this tube is screwed into the base plate I so that its end will deliver steam into the recess 8. 'I'he upper portion of the tube C passes through a shelf partition the en'd I6 ofwhich is adjacent a depending vertically disposed baiile I5 extending across the shell adjacent the end I6 of the shelf partition to deflect the splash water as stated in my prior application. The shelf referred to cooperates with the baille I5 and the upper portions of the walls of the shell to provide a steam chamber.

The tube C has its upper end D disposed closely adjacent a cover plate E which lhas on its underside a curved recess F to allow room for entrance of steam intothe end D of the tube similar to a steam dome and yet obstruct splash water entering the end D should such water find its way past the baille I5 and above the shelf. The cover plate has an overhanging or rabbeted edge provided with a gasket G and held in place by screws H to make a tight joint. The vertical baille I5 is in close contact with the bottom surface of this cover plate.

The prior application described a vent I'I in through the shelf and'in front of the steam passage I 2. To avoid any splash water passing upward through this opening Il, I provide in the present application a spring cover I inclined closely adjacent to the opening I1 at its forward end extending into a recess iv that guards it against undue pressure at its free end, the spring being held at its rear end by a screw J to which access is-given when the -cover plate E is removed. I provide tapped holes K--K'A in front and rear portion of the shell respectively by which a suitable handle is secured to the shell as indicated by dotted lines in Fig. 1. l

Besidesthe fastening screw B before mentioned for the front of the sole plate fasteningJ provide said screw L at the rear of thebase plate and firmly secured in the rear end of the sole plate adjacent the square -end 3. The open recess M in the rear end of the shell back of the rear wall N has suitable electric cord plug connectors O for attachment of the usual plug for the electric wires as describedin my prior application.

The rearward recess 8 in the sole plate is provided wth a suitableelectric heating element 9 connecting to a source of electricity as described in my prior application.

Reference is made to said prior application of mine for other features of construction in this present application that are similar in the two applications but not described or claimed in the present application.

It has been found by actual demonstration that the present improvements facilitate the manufacture and assembling of the various parts, and also increases the effectiveness of my iron in manipulation of the same in the process of using it as a smoothing iron, and in avoiding leakage of the splash water into the passage i2 and undesired exit of said water from the front recess The conical recess A with the inclined openings 'i' communicating with the steam recess B, improves the application of the steam to the goods being smoothed by the passage of the sole plate over the same after the application of steam through the described communicating passage 1 into the conical chamber A as the iron passes forward and backward over the fabric being smoothed.

The present construction of the passage i2 by means of the independently` attached tube C lessens the cost of construction and assembling of the same, and the location of its upper end D close to the cover plate and to the upward recess F, facilitates the lentrance of the steam into the end D and also tends to avoid anysplash water entering the tube should such water pass the baille I5 and gain admittance above the shelf.

It has also been found that the spring cover I obstructs the water that is splashed upward through the opening i1 in the usual, or unusual manipulation of the steam iron.

Referring again to the fastening screws B and L at the front and back ends respectively, it willbe seen that the screws pass into solid portions adjacent and that they do not enter or pass through any portion of the water chamber.

Thus there is no danger of leakage of water from the chamber through the fastening connections. This is an important feature of my iron.
