4 Claims. 1

This invention relates to a steaming and pressing device for ironing various materials in which the material may he .dampened and .pressed in one .and the same operation and. flow of vapor is controlled, as well as the .degree of heat used, in heating the device .and in generating .the steam for the ironing operation.

In accordance with this invention a steam ing and pressing viron is produced having the followingattributes. The device embodies improve ments construction whereby to attain the proper .thermal .efliciency for generating water into steam ,or vapor without leakage, ready 4and in the desired moist condition at all times, and especially when starting ironing operations. The iron will be of such design that it may be manually operated .with .comparative ease. Due tothe structural features the iron may be manufactured ,economically ,and the `parts thereof may be readily assembled yto produce vthe -device and such parts also may be easily disassembled and reassembled for the maintenance of the iron in the proper working condition.

With `the foregoing and other objects in View the invention will be understood from the following vspecication read in conjunction with the accompanyingdrawing, in Whichy Fig. 1 is a side view -of a steaming vand pressing ironv shown partly in longitudinal `section and embodying the features of the present invention.

Fig. 2 is a sectional View taken approximately on the line 2-2 of Fig. 1.

Fig, 3 is .a sectional view taken approximately on the line `3---3 of Fig. 1, certain parts of the iron are omitted.

Fig. 4 is a sectional View taken on the line 1 -4 of Fig. 1.

Fig. 5 is a sectional View taken approximately on the line 5-5 of Fig. 1.

Fig. 6 is a diagrammatic view illustrating the various water and steam `generating passages, steam `expansion chamber and distributing .passages together with the control valve means, it being understood that of the connections and the relative disposition of the features are eX- -aggerated due to the nature Aof the illustration.

Referring now more particularly to the drawings, it .will be apparent there is shown a manually operable steaming `and pressing iron l1] including a Weighted or metal body Il comprising a base or steaming and pressing section I2, an intermediate upper Water intake and steam generatingsection I3, and a top enclosing section I4, The sections I2, I3 and M are held in assembled :body forming relation by screw bolts t5. The sections l2 and I3 are heated .by means vof an electric vheating elementl .6 of any suitable type, the heating element :being .disposed between the sections Iz2 and I3. VThe sections I2, i3 and are of 4the usual shape; straight .at ythe rear with curved sides converging -to a point at the iront.

tifater enters a preheating coil il! of tubing connected with a nipple ,i8 by a cw coupling i9, the top section vi'li 'having an opening therein to accommodate the coupling. The nipple 1.8 is integral with the section i3 vand communicates with a tortuous conduit means or passage 2li formed in the section .IS in any suitable maner. .In the present instance this is done 'by drill ing and plugging as a .practical way in which .to obtain a ylong and continuous passage in which `the Water is initially subjected Vto heat by conduction to generate it into steam or vapor. The passage 2i@ consists of four interconnected V- shape branches 2|, '22, 23 and 2i, respectively. The branches .2i and 22 are of substantial size, and the branches 23 and Q4 are also of substantially the same size, but 'they are smaller than the branches ,2-I and .22 and lie within the latter. The branches 2I Yand 23 lie ina plane above the .plane of the branches 22 Yand .24. The .iiow .path or" the water or steam as .the case may be, is through the `

branches

2l, 22, 23 .and .24 in the order mentioned, and as indicated by the arrows in Fig. 6.

The passage 2) communicates with a conduit means or passage 25 formed in the base section lf2 in the manner explaineo` hereinabove. and said passage 2-5 constitutes a secondary steam generating means which derives heat by conduction "gfrom the heating element i6. The passage 25 Aconsists of ytwo interconnected V-shape .branches fand 2l, respectively, one lyingwithin the other and .both in the vsame plane. The outlet .end of the passage 2c is connected with the inlet end of the passage 25 by Van external iiow coupling 28 at the rear of the body II, there being an L-shape tubuiar iitting 2.9 carried -by the section I3 communicating Ywith the outlet end of the passage .29, and a nipple 3Q on the section I2 communicating -with :the inlet end' of the passage -2-5, the `coupling 28 Vbeing connected -fwith said iitting 29 and the nipple 36 as shown in Figs. 2 and 3.

The base section 22 is larger than the upper section I3 and has a recess SI in the top. The recess is similar in shape to that of the section I3 in plan, The recess 3l accommodates the 3 heating element it and approximately the lower half of the section i3. The section l2 has an enlargement at the rear extending transversely thereof, as shown in Figs. 1 to 4 inclusive. A steam expansion chamber 33 is formed in the enlargement 32 in any suitable manner, as by drilling or molding. rlhe outlet end of the passage 25 communicates with the chamber 33 at one end 'by virtue of a duct 3d shown in Fig. 8. Steam entering the chamber 33 serves as a supply always ready especially when starting a pressing or ironing operation after the device has been idle. 'Ihe vapor in the chamber 33 is kept in the proper moist state without being too hot due to the location of the chamber in the body Il to the rear of the heating element ViV in spaced relation.

In order to control the flow of steam or vapor from the chamber 33, there is provided a manually operable valve 35 having an inlet 35 screwed into the enlargement 32 in communication with the interior of the chamber 33. 'Ihe outlet 3l of the valve is connected with a nipple E8 by a coupling 5S, and said nipple 38 is carried by the enlargement 32 in communication with a distributing passage All having a branch M in said enlargement paralleling the chamber 3S, and a V-shape branch 42 in the main portion of the section l2, as shown most clearly in Figs. 4 and 6. The section i2 has a series oi discharge orices d3 therein which communicate with each of the leads of the branch passage i2 and which open through the bottom pressing face of the section l2.

The valve 35 has a lever 4d disposed adjacent a handle i5 of the iron. The handle i5 is secured in place by the bolts i5. The valve 35 is self-opening. The lever 44 may be manipulated to allow steam to iiow from the chamber 33 into the passage il from which it flows out through the orifices d3 to the material to be steamed and pressed by the iron manipulated by the handle d5.

Water enters the coil il and is preheated therein as it flows through on its way into the passage 2B in the upper section i3. The passage is of considerable length and causes the water to flow to and fro with respect to the point of the iron repeatedly. The water is gradually generated into vapor which passes into the passage in the base section I2 where the vapor is attenuated to a desired degree before entering the expansion chamber 33 at the rear of the heated body l. The chamber 33 serves to avoid undue pressure and keeps a supply of steam available under control of the valve 35 for delivery to the distribution passage 40. The

passages

20 and 25 are so disposed as to absorb the heat conducted by the sections l2 and i3 in an effectual manner because the iiuid takes a path at one level, another path nearer the heating element, then takes a path farther from the element to the passage 25 below said element in the base section I 2. There can be no leakage between the sections I2 and i3 and only one exterior coupling is used to connect the passages 2!) and 25. The construction, arrangement and functions of the parts lend themselves to the economic production of irons and also make it possible for each iron to be kept in the proper working condition.
