Dec. 21, 1965 l. JEPSON ETAL PRESSING IRON 6 Sheets-Sheet 5 Filed Nov. 9, 1962 Dec 21, 1965 a. JEPSON ETAL PRESSING IRON 6 Sheets-Sheet 6 Filed Nov. 9, 1962 INVENTOR. MW? JAPSO/V, JOSt'P/S Z V/[CfA 5774/1 45 W4LCZAK aw/PM United States Patent 3,224,122 PRESfiiNG IRON Ivar l'epsen, Oak Park, Joseph L. Vieceli, Cicero, and Stanley Walczak, Chicago, Ill., assignors to Sunbeam Corporation, (Ihicago, llL, a corporation of Illinois Filed Nov. 9, 1962, Ser. No. 236,510 21 Claims. (Cl. 38-77) The present invention relates generally to pressing irons and more particularly to pressing irons capable of selectively operating as a steam iron, a dry iron or a spray iron. Specifically, the present invention is related to the invention disclosed and claimed in copending Jepson and Vieceli application, Serial No. 203,500, filed June 19, 1962.

Since the extensive use of synthetic fabrics, the steam iron has become an essential household tool and today it is probably used more than what is referred to as the dry iron. Many fabrics can be smoothed effectively only upon the application of heat when moisture is contained in the fabric and long before the steam iron became a household necessity, flat irons or pressing irons were provided with means for sprinkling or spraying the clothes. In the above-mentioned lepson and Vieceli copending application, there is disclosed a combined dry, steam and spray iron wherein two separate and distinct flash-type steam generators are employed. In this iron, steam is generated in a first generator of the flash-boiler type and this steam is supplied through ports in the sole plate so that the iron functions as a conventional steam iron. Additionally, a separate and independent flash-type steam generator is employed which is used not only to aspirate water from the water reservoir for spray purposes but to break the water particles into a very fine spray so that the fabric is not injured by drops of water or the like. The present invention similarly employs two separate and independent steam generators.

In steam and spray irons it has been common practice to have a water reservoir of relatively small volume built into the iron. Obviously, such a reservoir holds only a limited quantity of water. The user of such iron ha no way of knowing how much water is in the reservoir except that when no further steam is obtainable the user could assume that the reservoir was empty. It would be desirable for the user to be able to tell at all times what the situation is with regard to the contents of the water reservoir.

The pressing iron, today, whether it be a steam iron or a combined steam and spray iron includes a number of manually actuatable controls including a temperature control, a steam control, and in the case of a spray iron, a spray control. The housewife desires that the means for actuating these controls be located for fingertip manipulation. At the same time, the arrangement of these controls should provide a pleasing appearance. The temperature-responsive means controlling the temperature at which the sole plate operates must, of course, be located adjacent the sole plate, which is commonly beneath the rear portion of the water reservoir in the steam or the steam and spray iron. In order that manually operated temperature control means adjacent the top forward portion of the handle may be operatively connected to a thermal responsive means located below the rear portion of the reservoir, very complicated means have heretofore been provided, many times including passageways through the reservoir which add to the expense and decrease the volume of water that the reservoir will hold. It would be desirable to provide an improved means for transmitting motion from manual control means adjacent the top forward portion of the handle to the thermal responsive means beneath the reservoir adjacent the rear of the sole plate without requiring a passageway through the water reservoir.

3,224,122 Patented Dec. 21, 1965 In the above-mentioned Jepson and Vieceli application, a separate cover was provided for the first steam generating chamber for generating steam so that the iron may be operated as a conventional flash-type steam iron and the separate cover was also provided for the second steam generating chamber used to generate the steam for powering the spray. It would be desirable to provide two separate and independent flash-type steam generating chambers with a common cover, thereby simplifying the construction and reducing the cost.

Accordingly, it is an object of the present invention to provide a new and improved pressing iron of the dry, steam and spray type.

It is another object of the present invention to provide a pressing iron employing a water reservoir with means to indicate readily to the housewife the water level in such reservoir.

It is a further object of the present invention to provide in a pressing iron an improved handle construction including a transparent portion at the top thereof permitting the user to view through this transparent portion the various settings of the control means of the iron a well as the level of the liquid contained in the water reservoir of the iron.

Still another object of the present invention resides in an improved control arrangement in a steam iron for readily controlling the temperature settings thereof without complicated linkage means and the like leading from the top forward portion of the handle to the temperature responsive means associated with the sole plate of the iron.

It i another object of the present invention to provide an improved spray control means for the steam iron of the present invention.

It is a further object of the present invention to provide an improved cover plate for the two steam generators of a steam iron wherein one steam generator is utilized to produce steam for operation of the iron as a steam iron and the other is used to produce steam for operating the spray.

Further objects and advantages of the present invention will become apparent as the following description proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the claims annexed to and forming a part of this specification.

For a better understanding of the present invention, reference may be had to the accompanying drawings in :hich:

FIG. 1 is a perspective view of a pressing iron embodying the present invention;

FIG. 2 is a top plan view, somewhat enlarged, of the pressing iron of FIG. 1;

FIG. 3 is an enlarged sectional view taken substantially on line 3-3 of FIG. 2 with certain portions not fully cut away more clearly to illustrate the invention and with the switch controlling the current supply to the iron in the OFF position;

FIG. 4 is an enlarged sectional view taken on line 44 of FIG. 3, assuming that FIG. 3 shows the complete structure;

FIG. 5 is an enlarged fragmentary sectional view taken on line 5-5 of FIG. 3 with certain portions cut away, again assuming that FIG. 3 shows the complete structure;

FIG. 6 is a sectional view taken on the line 66 of FIG. 3, again assuming that FIG. 3 shows the complete structure;

FIG. 7 is a sectional view taken on line 77 of FIG. 3, again assuming that FIG. 3 shows the complete structure;

FIG. 8 is a sectional view taken on line 88 of FIG. 3 again assuming that FIG. 3 shows the complete structure;

FIG. 9 is a bottom view of the cover for the steam generating chambers, a top view being included in FIG. 8;

FIG. is an enlarged fragmentary sectional view taken on line Iii-14 of FIG. 8, assuming FIG. 8 shows the complete structure;

FIG. 11 is an enlarged fragmentary sectional view taken on line 1111 of FIG. 3 again assuming that FIG. 3 shows the complete structure; and

FIG. 12 is an elevational view of the pressing iron of the present invention supported on the heel rest therefor with certain portions cut away to illustrate the liquid level indicating means.

Briefly, the present invention is concerned with a pressing iron which will function both as a steam and as a dry iron and which also functions as a spray iron when desired. The spray is powered by a flash-type steam generator entirely separate and independent from the flash-type steam generator supplying steam to the iron when functioning as an ordinary steam iron, whereby the steam generator may be operated at a higher pressure than is possible with the generator supplying steam for an ordinary flash-type steam iron. A manually actuatable pump supplies water to the spray generator and a common reservoir supplies water to both the spray and steam generators. The handle is provided with chambers housing various controls and a transparent top is provided for the handle through which all the controls except the pump control are visible, including means for indicating the level of the liquid in the reservoir when the iron is tipped up on its heel rest, which heel rest in a preferred embodiment is formed of a molded plastic material. The pressing iron includes an improved mechanical connection between the temperature control knob and the temperature responsive means which in no way interferes with the water reservoir and yet provides a very simple and compact arrangement. A common cover is used for both steam generators. The spray control comprises a trigger mounted on the underside of the handle so that the operator by means of the thumb and forefinger during the ironing operation may actuate all of the controls.

Referring now to the drawings, there is illustrated in FIGS. 1 to 12 an electric pressing iron which in many respects is quite similar to that disclosed in the abovementioned copending Jepson and Vieceli application. Insofar as the features which are essentially the same as those disclosed in the above-mentioned copending application are concerned, they will be rather briefly described herein. As a matter of fact, a number of features are very similar to the features of the pressing iron disclosed and claimed in Jepson et al. Patent No. 2,906,043, granted September 29, 1959, and assigned to the same assignee as the instant application. The pressing iron 20 comprises a sole plate 21, preferably constructed of a lightweight cast metal, such as aluminum or the like. This sole plate 21 is heated in a conventional manner by an electric heating element 22 of the sheathed type (FIGS. 3, 4, 5, 6, 8 and 10). Sheathed heating elements are well known and generally comprise a helical resistance conductor centrally disposed within an outer sheath and supported in spaced relationship with respect to a sheath by an electrical insulating material which is also a good heat conductor. Such insulating material may comprise highly compressed magnesium oxide. As in the above-mentioned Jepson et al. patent, the sheathed heating element 22 preferably has a generally U-shaped configuration (FIG. 6) or, in other words, is in the shape of a hairpin. Also, as is best shown in FIGS. 3, 4, 5, 6, 8, 10 and 11 of the drawings, the sole plate is provided with a raised integral U-shaped rib 23 in which the sheathed heating element 22 is embedded. Projecting from the ends of the sheathed heating element 22 are electrical terminals 24a and 24b (FIGS. 5 and 11) which, as is fully disclosed in the above-mentioned Jepson et al. patent, are electrically connected in a circuit including a switch controlled by a temperature responsive device for controlling the heating of the sole plate 21 in any desired selected manner.

In order to produce steam on the flash principle and supply it beneath the sole plate 21 of the pressing iron 20, there is provided a steam generating chamber 25 which is in good heat transfer relationship with the heating element 22 and is defined within the space bounded by the outside edge of the U-shaped rib 23 and a vertical wall of cross member 26. The stream generating chamber 25 is best shown in FIG. 6 of the drawings, but is also illustrated in FIGS. 3, 4 and 10 of the drawings. The particular construction of the steam generating chamber 25 and the steam flow therein starting with the supply of water thereto and the conversion of this water to dry steam is such as to insure intimate heat exchange relationship with the heating element 22 while still permitting a somewhat similar relationship of the heating element with respect to the independent spray steam generator described hereinafter. As illustrated, water enters the steam generating chamber forwardly of an arcuate raised rib 27 having a pair of rearwardly directed wings and then flows rearwardly through channels 28a and 28b and through a labyrinth passageway defined by U-shaped raised portions 29a and 295 so as to be quickly converted into steam. A pair of forwardly directed passages 36a and 3% permit the steam to flow forwardly very close to the heating element 22 up to barriers 34a and 34b which together with means described hereinafter direct the steam directly along the fiat top of rib 23 to the front of the iron through passageways 35a and 35]) (FIGS. 4, 9 and 10) where the steam, which by now is free from water droplets, can flow rearwardly through an opening 36a in the inner wall defining the passageways 35a and 35b. The steam then passes into passageways 30c and 36d in the sole plate 21 which passageways extend rearwardly along the inner surface of rib 23 terminating in the barriers 34a and 34b. The steam is then discharged through ports 31 which lead to the underside of the sole plate and which are distributed over a substantial area of the ironing surface of the pressing iron 20. The sole plate 21 is preferably provided with a plurality of elongated grooves 32 (FIGS. 3, 4 and 10) which may be identical with those disclosed in FIG. 7 of the above-mentioned Jepson et al. patent. The steam pressure in the steam generating chamber 25, due to the presence of the continuously open ports 31, is generally less than one pound per square inch.

In accordance with the present invention, there is provided in the sole plate 21 a second steam generating chamber designated by the reference numeral 33 which is the U-shaped chamber disposed immediately outside the rib 23 so as to be closely adjacent the heating element 22, just as is the steam generating chamber 25. However, this steam does not flow along the top of rib 23 as provided by the steam generator 25. As will become apparent from the ensuing description, the steam generating chamber 33 is used to provide steam for powering a liquid spray and, as in the above-mentioned Iepson and Vieceli application, a much higher steam pressure is developed in the spray steam generating chamber 33 than in the steam generating chamber 25.

In order to complete the steam generating chambers, there is provided a common cover 36, best shown in FIGS. 3, 4, 8, 9 and 10 of the drawings, which is secured to the top of the sole plate by suitable fastening means 37. The underside of the cover 36, best shown in FIG. 9 of the drawings, is provided with depending ribs cooperating with the portions 26, 27 and 29a, 29b, 34a and 34b of the sole plate 211 to define the steam passageways for both steam generating chambers 25 and 33. The passageways 35a and 35b as shown in FIG. 9 of the drawings are defined primarily by the cover 36 and, of course, the top of rib 23. Consequently, the rib 23 has the top thereof defined in a plane which is common with the tops of the ribs 26, 27, 29a and 29b, and barriers 34a and 34b and a U-shaped rib 38 defining the outer boundary of the spray steam generating chamber 33. For locating the common cover 36, the top of the sole plate 23 is preferably provided with a pair of openings 39 and 40 (FIG. 3) for receiving corresponding projections 36a and 3612 on the underside of cover 36, as best shown in FIGS. 3, 6 and 9. The cover 36 is further provided with an opening 41 through which water may be supplied to the steam generating chamber 25 through a conventional needle valve, as is well understood by those skilled in the art. Additionally, the cover 36 is provided with a water inlet opening 42 and a steam outlet opening 43 (FIGS. 9 and both being connected to the spray steam generating chamber 33. The water inlet 42 is connected to the end of one leg and the steam outlet 43 is connected to the end of the other leg of the spray steam generating chamber 33 whereby in passing from the inlet to the outlet through the U-shaped steam generating chamber 33, water supplied thereto is quicky flashed into steam. It will be understood, that as in the copending Jepson and Vieceli application, the spray steam generator 33 is completely independent of the steam generator 25, and, consequently, it may be designed to produce much higher pressures than could be developed in the steam generator 25. Preferably a pressure of between thirty and fifty pounds per square inch is desirable in the spray steam generator 33.

For the purpose of supplying water to the steam generating chamber 25, there is provided in much the same manner as in the above-mentioned Jepson et al. patent a valve body member 44 which has the lower end thereof secured to the cover 36 of the steam generating chambers and 33 so that this valve body controls the flow of water through the opening 41 in the cover 36. As in the abovementioned Jepson patent, the valve body 44, which preferably has the lower end of reduced cross section inserted through the opening 41 and peened over so as to be firmly secured thereto acts as a support for the water reservoir generally designated at 45 which has a suitable opening therein aligned with a passageway defined in the valve body 44. A suitable bushing nut 46 (FIGS. 3, 7, 8 and 10) secures the reservoir 45 to the common cover 36 of the steam generating chambers 25 and 33 and, hence, of course, secures the water reservoir to the sole plate 21. At the same time, the member 46 defines a metering orifice which may be selectively opened or controlled by raising and lowering a metering valve element 47.

From the above description, it will be apparent that water under the force of gravity enters the steam generating chamber 25 immediately beneath the needle valve element 4-7, as best shown in FIGS. 3 and 10 of the drawings. This water, which is quickly flashed into steam by virtue of the high temperature of the walls defining the steam generating chamber 25, moves rearwardly through labyrinth passageways and then forwardly along the inside walls and on top of the U-shaped rib 23 defining the passageways a and3lb, whereby dry steam will pass through the ports 31 and into the grooves 32 defined on the underside of the sole plate. Preferably, the water reservoir is provided with a conventional baffle 48 (FIGS. 3 and 7) clamped in place by the lower end of a stud 49 which has a threaded end 4% projecting from the top of water reservoir 45 and in sealed relationship therewith.

In order selectively to control the temperature of the sole plate 21, there is provided a thermoresponsive control device generally designated at 50 and which is preferably mounted in a well 51 defined on the upper side and toward the rear of the sole plate 21, as best shown in FIGS. 3, 5 and 11 of the drawings. The temperature responsive control device 59 is preferably mounted beneath the water reservoir 45 and between the legs of the U- shaped rib 23 rearwardly of the wall 26 defining the rear wall of the steam generating chamber 25. It comprises the conventional bimetallic element 52 secured to the sole plate 21 by fastening means 52a which element 52 controls the opening and closing of a switch 53 defined by a pair of relatively movable contacts 53a and 53b, respectively (FIGS. 3 and 11). In accordance with the present invention, there is provided a somewhat L-shaped lever or bell crank 54 which is pivotally mounted as indicated at 55 (FIG. 11) to the remainder of the temperature control mechanism 50 so as to selectively position the contact 53b of the switch 53. In the position shown in FIG. 3 of the drawings, the switch 53 is in the open position. The bell crank 54 includes a long, upwardly extending arm, the purpose of which will become apparent from the ensuing description.

The details of the temperature responsive control means 50 and the electrical circuit connected to the terminals 24a and 24b of the sheathed heating element 22 form no part of the present invention and no further description is included herewith. It will be understood that the switch 53 controlled by the bimetal or bimetallic element 52 will control the current supplied to the heating element 22 in a manner understood by those skilled in the art. An important feature of the pivotally mounted lever or bell crank 54 is that it is pivoted beneath the reservoir 45 and extends around the back of the same so as not to interfere in any way with the volume of the reservoir nor to require a passageway therethrough as was commonly required with prior art arrangements.

So that the pressing iron 20 of the present invention provides a more pleasing appearance insofar as the top of the sole plate and the parts supported thereon, such as water reservoir 45 and the temperature responsive control means 5t), are concerned, there is provided a cover shell 56 which is provided with a suitable somewhat keyhole-shaped opening 57 at the front thereof and a small opening 58 at the rear. The opening 57 is necessary to afford access to the water reservoir 45 while the opening 58 accommodates the water gauge described hereinafter. The cover shell 56 is provided with spaced rearwardly directed tabs 56a (FIGS. 3 and 5) whereby the cover shell may be secured to a somewhat H-shaped bracket support 59 (FIGS. 3, 5 and ll) attached to the sole plate 21 by suitable fastening means 69 in a manner similar to that disclosed in the above-mentioned lepson et al. patent. The front of the cover shell 56 is provided with an extension of the opening 57 through which the threaded end 49a of stud 49 extends whereby it may be used simultaneously to secure a handle 62 described hereinafter to the shell 56 and reservoir 45.

A suitable handle 62 is provided to permit the operator to manipulate the pressing iron in the desired manner. This handle is preferably formed of a molded insulating material, such as one of the many synthetic resins capable of withstanding relatively high temperatures in the neigr borhood of 275300 F. As illustrated, the handle 62 is substantially of D-shape and comprises a base or skirt portion 62a of somewhat the same configuration as the upper surface of the cover shell 56 and a pair of somewhat vertical posts 62b and 620 interconnected at the top by a hand grip portion 62d. This entire handle is preferably molded in a one-piece construction. Both the front and rear posts 62b and 620 are hollow and, as illustrated, the rear post 620 defines a chamber 63 into which the upwardly projecting portion of the bell crank 54 extends, as well as other elements described in detail hereinafter. The hand grip portion 62d is also hollow but contains a pair of spaced upwardy extending ribs 622 and 62 best shown in FIG. 3 of the drawings. The chamber defined in the hand grip portion 62d is designated by the reference numeral 64. The forward post 62b is also provided with a hollow chamber and the needle valve control member 47 extends upwardly through this chamber 65 and through an integral wall portion 62g which separates the chambers 64 and 65. The wall portion 62g effectively defines the top of the chamber 65 and this wall portion is provided with a plurality of openings designated as 67, 68 and 69, the latter defining an opening through which the control rod 47 for the needle valve extends.

The lower portion of the chamber 65 is conected through the opening 57 in the cover shell 56 to an opening 70 in the water reservoir 45 defined by a circular upturned rim or flange 45a. To provide a watertight seal at the junction between the handle chamber 65 and water reservoir 45, there is provided a metal ring 72 secured in the circular portion of opening 57 in cover shell 56 thereby defining an annular space between ring 72 and upturned rim 45a. A suitable sealing gasket 73, preferably formed of silicone rubber, and in the form of an inverted cup, has its depending anular flange disposed in sealing relationship between the ring 72 and an annular flange 45a. As is best shown in FIGS. 3 and 4 of the drawings, the sealing gasket 73 makes sealing engagement between the handle 62 and the water reservoir 45, whereby any water supplied to the chamber 65 must enter the opening 76 and flow into the water reservoir 45.

In order to secure the handle 62 to the rest of the pressing iron and simultaneously to hold the gasket 72 in sealing engagement with both the reservoir and the handle 62, the front post 62b of the handle 62 is provided with a recess 75 into which the threaded end 49a of stud 49 may extend through a suitable opening in the wall defining the bottom of this recess. By means of a nut 76 threadedly engaging the threaded end 4% of stud 49, the front of handle 62 is clamped to the remainder of the pressing iron 20 in a manner compressing the sealing washer 73 into sealing engagement as best shown in FIGS. 3 and 4 of the drawings. Actually, as will become apparent from the ensuing description, the stud 49 and nut 76 also clamp a U-shaped control supporting frame 77 into position (FIGS. 3 and 4) within recess 75, the stud 49 passing through the bight portion 77a of this frame 77. The rear portion of the handle 62 is secured by suitable screws 78 to the bracket 59, as best shown in FIG. 5 of the drawings. These screws 7 8 extend through the tabs 56a of cover shell 56 thereby camping the rear portion of cover shell 56 and handle 62 to the bracket 59.

For the purpose of filling the reservoir 45, a filling passageway 65a is provided which is effectively a lateral extension of the chamber 65 opening at the front of post 6211, as is clearly shown in FIG. 3 of the drawings. It will be apparent that when the iron is resting on its heel in the manner shown in FIG. 12 of the drawings that water may readily be poured into the passageway 65a. This passageway 65a, as will become apparent from the ensuing description, also receives the spray nozzle so that the spray may be projected from the open end of this passageway leading to the front of the iron, and, of course, it is also the passageway through which the contents of reservoir 45 may be emptied. Preferably, and for decorative purposes, the entrance to the passageway 65a is defined by a collar or flange member 79 secured in any suitable manner to the walls defining the open end of passageway 65a.

As in the above-mentioned Jepson and Vieceli copending application, water is supplied to the inlet opening 42 of the spray steam generator 33 from the water reservoir 45. Since the pressure in the spray steam generator 33 may be relatively high, a suitable pump, generally indicated at 81 (FIGS. 3 and 4) is provided. As in the above-mentioned Jepson and Vieceli application, the bottom of the reservoir 45 is provided with a depending pump well 82 for the pump 81. The bottom of this well is provided with an opening 83 comprising the pump outlet which is connected to a water conduit 84 and a check valve 85 to the water inlet opening 42 in the cover 36 leading to the flash-over spray generator 33. Connected to the steam outlet opening 43 of the spray generator 33 is a steam conduit 86 (FIGS. 3, 4, 7, 8 and 10) which is disposed outside the reservoir 45, the reservoir preferably being provided with a groove or indentation 87 along one side and over the top for receiving this steam conduit. To insure a satisfactory seal between the spray steam generating chamber 33 and the check valve 85 and steam conduit 86, annular sealing gaskets 88 and 89 are provided. These gaskets preferably formed of a silicone rubber are compressed between cover 36 and reservoir 45, as best shown in FIG. 10 of the drawings. Preferably cover 36 is provided with raised projections 36c and 36d for retaining the lower portions of gaskets 88 and 39, respectively.

Steam conduit 86 is connected to a spray nozzle 90 located in the passageway 65a at the forward part of the handle so as to discharge a fine spray of water particles broken up by the steam through the filling opening for the reservoir 45 and, consequently, in front of the sole plate 21. The spray nozzle 99 may be substantially identical with that disclosed and claimed in the above-mentioned Pepson and Vieceli copending application. As in that copending application, a water conduit 91 is connected to the spray nozzle 99 which conduit has its inlet end disposed in a well 92 defined in the bottom of the water reservoir 45, as best shown in FIGS. 4 and 7 of the drawings. Preferably the lower end of the water conduit 91 is provided with a suitable screen 93 to prevent any foreign matter adjacent its inlet end from reaching the spray nozzle 90. Similarly a screen 94 (FIG. 10) is provided for the inlet end of steam conduit 86. The steam flowing through conduit 86 and entering nozzle 90 draws water through water conduit 91. This water in nozzle 90 is broken up into fine particles of water so as to produce a spray of very finely divided water particles and steam.

It will be appreciated that the pump 81 is necessary to supply water to the spray generator 33 against the relatively high pressures that are developed therein and the check valve 85 is provided to prevent any surging of steam back through the conduit 84 when the pressure produced by the pump 81 is released. The pump 81 may be substantially identical with that disclosed in the abovementioned Jepson and Vieceli copending application and is illustrated as comprising a piston 95, preferably molded from a suitable resilient material connected to a reciprocating pump rod 96. The piston 95 is disposed for reciprocation within the pump well 82 and the pump rod 96 eX- tends through the chamber 65 in the handle 62 and through the opening 67 in wall 62g so that the upper end thereof is disposed within the handle chamber 64. A suitable compression spring 98 surrounds the upper end of the pump rod 96 above the wall portion 62g and is compressed between wall 62g and means secured to the upper end of rod 96 to normally bias the pump rod 96 and the associated piston 95 to the upward position shown in FIGS. 3 and 4 of the drawings. It will readily be apparent that when the piston 95 is in the uppermost position shown, water from the reservoir 45 may enter the well 82.

For the purpose of guiding the lower end of the pump rod 96, the upper end being guided by the opening 67 in the wall 62g, and also to prevent foreign matter from entering the pump well 82, there is provided a screen member 1% (FIGS. 3, 4 and 7) overlying the pump well 82. The screen is provided with a frame having an extension 109a which is clamped into position by the means 46. An opening in the upper part of the screen guides the lower end of the pump rod 96.

An important feature of the present invention resides in providing a transparent closure for the top of chamber 64 in the handle 62. To this end the top of handle 62 is provided with an elongated opening 103, the boundaries of which are defined by a peripheral ledge 1104, best shown in FIG. 4 of the drawings. Supported on this ledge is a transparent closure member 105, the forward end of which is preferably held in place by the member 79, as best shown in FIG. 3 of the drawings, and the rear end of which is secured to the handle 62 by a suitable fastening means 197. Supported on the ledge 194 beneath the transparent member is a thin, flexible member 198 which preferably includes suitable indicia with respect to the control means described hereinafter. The flexible indicia supporting member 163 is provided with an elongated slot 109 which provides a viewing window for a water level gauge comprising a transparent tube 110, best shown in FIGS. 3, 4 and 11 of the drawings. As is clearly shown in FIG. 3 of the drawings, this liquid level gauge or tube 116 is preferably formed of transparent material and has an intermediate portion thereof supported within aligned notches 111 and 112 defined in the top of ribs 622 and 62 so that this intermediate portion will be held directly beneath the viewing window 109. One end of the liquid level gauge 110 extends through handle chamber 63 and is connected to the rear top portion of the reservoir 45, as indicated at 113 (FIGS. 3, and 12), while the forward portion thereof is connected to a suitable nipple 114 disposed in the opening 68 in the wall 62g of handle 62. When the iron is in the ironing position shown in FIG. 3 of the drawings, no water will be present in the liquid level gauge or indicator 110 regardless of the amount of water in the reservoir 45. However, when the pressing iron 20 is placed on its heel rest, as shown in FIG. 12 of the drawings, it will be apparent that the connection 113 at the rear of the water reservoir 45 then becomes a connection at the very bottom of this reservoir when in the upended position. Morever, Water will flow into the liquid level gauge 110 so as to indicate as clearly shown in FIG. 12 of the drawings the level of the liquid Within the reservoir 45 and, thus, indicate to the user the amount of water contained in this reservoir. It is obvious that the user will periodically place the iron on its heel rest, as shown in FIG. 12 of the drawings, and on those occasions can readily determine the amount of water contained in the water reservoir. Preferably the portion of the transparent tube 11% disposed immediately beneath the window 169 and visible through the transparent cover 1G5 has the bottom thereof coated with a narrow line of a bright colored material. When the plastic tube 11% is filled with water, the magnifying or lens etlect of the water in the cylindrical tube will cause this colored line to be greatly magnified and will indicate precisely and readily to the user the level of the liquid in the tube 116 when disposed in the position shown in FIG. 12 of the drawings, and, consequently, will indicate the amount of water contained within the reservoir 45.

For the purpose of manually actuating the pump 81 there is provided a finger-actuated trigger member 115 disposed in a recess defined in the underside of the handle portion 62d, as best shown in FIG. 3 in the drawings. This trigger member 115 is in the nature of a lever pivotally mounted about a pivot shaft 116 suitably supported in the U-shaped control supporting frame 77', as best shown in FIG. 4 of the drawings. The trigger 115 is provided with a bifurcated portion comprising side plates 115a and 11517 through which the pivot shaft 116 extends, which side plates are interconnected at the end remote from the finger-engaging portion 115C thereof by a cross piece 115d. This cross piece 115:! is adapted to overlie the upper end of the pump rod 96. The compression spring )8 biases the trigger 115 in a clockwise direction about shaft 116 as viewed in FIG. 3 of the drawings and this clockwise rotation is limited by virtue of a lug 115a on the trigger 115 engaging a projection 62h provided in the handle portion 62d, as clearly shown in FIG. 3 of the drawings. It will be apparent that the housewife whose fingers encircle the hand grip portion 62d of the handle 62 can readily manipulate the handle engaging portion 115s of the trigger 115 with the forefinger of her hand and, thus, actuate the pump 81 with the result that a spray is produced at the nozzle 99.

It should be understood that the openings 67, 68 and 69 in the wall portion 62g of handle 62 are provided with suitable sealing means, not shown, so that water poured into the filling opening comprising the passageway 65a leading to chamber 65 will not be able to enter the chamber 64 through these openings.

In order to provide fingertip control of the metering valve element 47, there is provided a control knob shaft 118 (FIGS. 3 and 4) supported :by the upper ends of the control supporting frame 77 within chamber 64. This shaft 118 is disposed in spaced parallel relationship with trigger pivot shaft 116. Rotatably mounted on this shaft 118 is a manually actuatable steam control knob 119 preferably in the form of a segmental disk having a laterally projecting hub portion 119a from which there extends in a forward direction a forked portion 11% for receiving therebetween a portion 47a of reduced cross section of the valve element 47 disposed within chamber 64. An L-shaped projection 77b of the U-shaped control supporting frame 77 supports an upwardly extending pin 121 for retaining the lower end of a compression spring 122, the upper end of which engages an integral projection 11% of the manual steam control knob 119. So that the housewife may readily manipulate knob 119, a portion thereof extends through aligned openings in transparent closure member 195 and flexible indieia supporting member 168. The opening in transparent cover member for knob 119 is designated as 124. The finger engaging portion of the steam control knob 119 is preferably knurled, as best shown in FIG. 2 of the drawings, so that it may readily be actuated by the housewife. It is intended that this control be either in the open or closed position. Preferably suitable indieia may be applied to the top surface of the flexible indieia supporting member 188 adjacent the steam control knob 119 which will be visible through the transparent closure member 195 and Will indicate the ON or OFF condition of the steam control.

For the purpose of providing sel ctive temperature control, there is also rotata bly supported on the shaft 113 a temperature control knob 125 which is preferably in the form of a knurled disk having the knurled portion thereof projecting through aligned openings in transparent member 1115 and flexible indicia supporting member 1118 in the same manner as knob 119. The opening in member 165 for knob 125 is designated as 127. R0- tatable with the temperature control knob 125 is a gear 128 which engages teeth 129 arranged in a rack-like manner on an elongated longitudinally movable force transmitting member 130 disposed in chamber 64 and slidable in suitable aligned grooves or notches, not shown, defined in ribs 62c and 62 respectively, which may be similar to notches 111 and 112. Preferably the longitudinally movable force transmitting rod 130 is provided with a looped portion 130a and the rack teeth 129 are defined along one edge of the means defining the loop portion so that the gear 128 is received within the plane of the loop and, consequently, the ends of the loop will determine the extreme limits of movement of the rod 130. The rear end of the rod 139 is connected by suit able adjustable coupling means 132 with the bell crank 54-, the adjustable means 132 providing for calibration of the temperature control means.

In order to provide an indication of the particular setting of the temperature control knob 125, the force transmitting rod 13% is provided with a cross member 13% at the forward end thereof movable with the rod within the chamber 64. This cross member is preferably coated with a colored material of a highly reflective type such as a daylight fiuoroscent coating. Preferably, also, the flexible indieia supporting member 108 is provided with a plurality of pairs of spaced openings 134, as best shown in FIG. 2 of the drawings, and with suitable indicia indicating the particular setting of knob 125 when the cross member is visible through particular pairs of said openings, thus indicating to the user the particular temperature setting. It will be appreciated that the temperature control means described in no way interfere with the water reservoir 45 since the mechanical connections comprising elements 54 and 13% extend around the exterior thereof.

It should be understood that the pressing iron of the present invention may have the conventional metal heel rest which has heretofore been employed in which case the cover shell 56 would be provided with an extending portion projecting beyond the rear of the handle 62 and the projecting portion would be closed by a suitable closure plate, as fully disclosed in the above-mentioned .lepson et al. patent. In accordance with the present invention, however, there is provided a molded plastic heel rest, generally indicated at 136, best shown in FIGS. 3, and 11 of the drawings. The forward portion of this heel rest adjacent the sole plate 21 is preferably provided with a pair of spaced recesses 13% and ll37b for receiving projections 59a and 59b of the bracket 59 which projections extend beyond the rear of the sole plate 21, thus positioning the heel rest 136 relative to the sole plate 21. A single fastening means in the form of a screw 13? threadedly engages a tapped opening in the handle 62 securely to hold the plastic heel rest 136 in position. The plastic heel rest is preferably provided with openings 139 and 140 on either side thereof for accommodating the conventional strain relief 141 associated with the usual power cord. Two openings are provided so that the iron may have the power cord coming in either on the right hand side or the left hand side depending on whether the housewife is right handed or left handed. In FIG. 5 of the drawings, the strain relief 141 is disposed in opening 140 and the opening 139 is closed by a suitable closure plus 142. Obviously, strain relief 141 and plug 14?. may have their positions interchanged.

It will be understood that the terminals 24a and 24b of the heating element 22 are connected by suitable conducting members 143 and 144, respectively, with a stack of interleaved insulating and conducting members, generally designated as 146 forming a part of the temperatureresponsive control means 5t Electrical connections with the conductors in the power cord are also made to the stack 146 in a manner well understood by those skilled in the art so that when the switch 53 is closed and the power cord associated with the strain relief 141 is connected to a source of electric energy, the heating element 22 is energized.

In view of the detailed description included above, the operation of the pressing iron of the present invention will readily be understood by those skilled in the art. The operator by means of the thumb and forefinger can control the water pump, the temperature setting and the steam control knob. When it is desired to produce a spray, the operator merely actuates the trigger 115 which causes water which has accumulated in the pump well 82 to pass through the passageway 83, through the conduit 84 and the check valve 85 into the inlet of the spray steam generator 33. Due to the restricted passageways involved, a sustained supply of water will be provided over a period of time, such as five to ten seconds, with one actuation of the trigger 115. This water will be instantly flashed into steam and by the time it enters the spray nozzle 90, it will be in the form of superheated steam so as to cause water particles aspirated through water conduit 91 to be broken up into fine water particles and mixed with the steam.

When the pressing iron 2ft is set upon its plastic heel rest 136, the water gauge 110 will be effective to tell the housewife the amount of water contained within the reservoir 45. It will be appreciated that there has been provided a pressing iron which may be used as a steam, a dry or a spray iron and in which the optimum operating conditions of the spray principle, the steam principle and the dry ironing principle may be employed. Moreover, a very simple construction of two separate steam generators with a common cover plate for both steam generators has been described and novel means for actuating the temperature controls, pump and steam controls are included.

While there has been shown and described a particular embodiment of the present invention, it will be apparent to those skilled in the art that various changes and modifications may be made without departing from the invention in its broader aspects and it is, therefore, contemplated in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
