Application January 19, 1939, Serial No. 251,683
1 Claim.
This invention relates to pressing irons, and more particularly to an improved construction of iron which is electrically heated and to which water is supplied and generated into steam in successive stages and discharged in the form of super-heated steam in direct contact with the article being ironed.
A further object is to improve upon the construction of iron disclosed in Patent No. 2,123,002 granted to me July 5, 1938.
My improved iron embodies many novel features of construction and combinations and arrangements of parts, all of which will be more fully hereinafter described and pointed out in the claim.
In the accompanying drawings Figure 11s a top plan view of the iron;
Fig. 2 is a view in longitudinal section through the iron, the view being taken on the staggered line 2--2 of Fig. -1;
Fig. 3 is a sectional plan view, the view being taken on the staggered line 3-4 of Fig. '2;
Fig. 4 is a view in vertical transverse section on the line 44 of Fig. 2;
Fig. 5 is a fragmentary detail view in section on the line 5-5 of Fig. 1;
Fig. 6 is a fragmentary view in section on. the line 6-8 of Fig. 3;
Fig. '7 is a longitudinal vertical sectional view through Fig. 8 on the line 1-1, the same disclosinga modified form of the invention to that illustrated in Figs. 3 to 5; 7 7
Fig. 8 is a sectional view through Fig. approximately on the line 8-8; I
Fig. 9 is a detail fragmentary sectional view through Fig. 8 on the line 8-8.
My improved iron is formed with a base or bottom member ill, a covering plate or top member II and an intermediate block or casting i6 which is mainly housed within the base It! and top member ll except at the rear of the iron, as shown more clearly in Fig. 2 of the drawings. These parts are securely clamped together by removable screws 12 and I3 to facilitate their assemblage. An electric heating element i 4 is lothe bottom of the iron throughout the forward portion thereof is provided with steam-escape orifices 20 through which the steam escapes on to the fabric while it is being ironed. The rear portion of the iron in its under face or bottom is free from such orifices, thus-leaving the hot smooth portion of the iron tosmooth out the goods. The transverse passage I! also communicates with a series of orifices 2| (Fig. 4)- in the base of the iron so that this passage I9 and the chambers l8 form a communicating superheating chamber which discharges through the orifices above described in the bottom of the iron.
The block or casting I6 is formed with heating chambers 22 and 22' which merge together at the front of the iron and in effect form one large heating chamber. During the operation of the iron, water passes into the part 24 which is located at the rear of the iron and preferably in contact with the iron so that the heat radiating from the iron will heat the coil and initially heat the water so as to raise its temperature and facilitate the formation of steam in chamber 22. As a matter of fact, the water entering the hot pipes 23 and 42 will turn into vapor or very lowpressure steam before it is discharged at point' each time the valve 29 is opened and, consecated in the base under and in direct contact ends of the iron by a transverse passage 19, and
quently, additional steam or ,vapor may pass into chambers 22 and 22' from pipes 23 and 42. It will be observed from Fig. 3 that pipe 23 extends from fitting 23' and also the auxiliary pipe 23" extends from fittings 23' in a direction substan tially at right angles to pipe 23. Pipe 23" extends along the' rear of the iron and absorbs a certain amount of heat therefrom. From the rear of the iron, pipe 23" extends around to an opening 22" where the end thereof ,is clamped by member 4| which is similar tomember 40 associated with pipe 23. The pipe 42 is fitted into an aperture in the hollow boss 43 so that steam in chamber 22 and 22'. From chamber 22 steam is directed through a passageway 23, thencethrough a screw-controlled passage 23 into a passageway 21 which communicates with...
The movement of steam from chamber 22 into chamber 28 is manually controlled by a needle valve 29 having a spring 30 thereon holding the valve in normal closed position, and a manually movable pivoted lever 3| is operatively connected to the valve so as to permit the same to be opened when the lever is operated, and this lever carries a set screw 32 which is adapted to engage a ledge 33 to limit the opening movement of the valve. The valve is mounted in a block or casting 34 which is secured by screws 35 to the block or casting l6 and the passages 25 and 2? above described are jointly in the blocks 53 and 34 and the gaps between these blocks are bridged by tubes 36 to prevent leakage.
The chamber 28 has an outlet 37 which cornmunicates with a vertically extending duct 38, which latter is in open communication at its lower end with the central portion of the transverse superheating chamber or passage i9. In the lower part of the duct 38 is arranged a tubular screw 39 through which steam is directed into the chamber or passage I9. This screw acts in the double capacity of means for directing steam into chamber I9 and also means for clamping the casting l6 against the base l0.
In use the coil 24 is provided with water from a water main under the usual pressure of the water main and the water passes from the main into and through coil 24. From coil 24 the water or vapor therefrom passes through pipes 23 and 42 into the respective chambers 22 and 22'. These chambers may be termed the initial heating chambers where sumcient heat is applied to the vapor to turn the same into a steam of relatively low temperature and pressure. From time to time as steam is desired to be used for pressing operations, the operator depresses the lever 3|, opening needle valve 29 momentarily and permitting a certain amount of steam to pass from the initial heating chamber 22 into the second heating chamber 28 where the temperature of the steam is increased, and from this chamber 28 the steam passes into the passages or chambers I 8 and is in the parts of the iron where the steam is superheated and escapes through the orifices 20 and 2i. Thus it will be seen that the temperature of the steam is raised in stages and the most efficient results are had by so doing.
Referring more particularly to Figs. 7 to 9 inclusive, it will be seen that the steam generating block IS is a single casting and in addition to being constructed as shown in Figs. 3 to inclusive, is formed with bores 45, M and 38. As illustrated in these figures, the fitting 23' and associated parts as shown in Fig. 3 are used, and in addition there is provided a short pipe or tubular member 45 which provides a communication between fitting 23' and the bore 48. As 11- lustrated in Fig. 8, bore 46 is in free communication at all times with the bores 41 and 48. which bores converge or substantially converge toward the front and discharge into an opening 49 which in turn discharges at the front part of the front chambers 22 and 22'. Chambers 22 and 22' and the rear chamber 28 in this form of the invention are identical with that shown in Fig. 3. As a matter of fact, the entire construction is identical with that shown in Fig. 3 except for the bores d6, ti and 48 and associated parts. The bores Just mentioned are all preferably drilled and, consequently, one end of each bore must extend through the exterior surface of the casting. Suitable plugs be close the respective ends of bore it and suitable plugs 5! close the respective ends of bores d! and 38. By reason of this construction,
water from the coil 2% will pass through the fitting 23 and be discharged by the respective pipes 23 and s2 into the front part of the front chambers, while at the same time water will pass through the passageways as, all and 68 and be discharged through the opening 39 into the front part of the front chambers. As the steam generating block it is made of cast metal, as for instance cast iron, and is heated by the heating unit 86, the water by the time it enters the front chambers will be vapor or low grade steam as it is heated in its passage through the various bores and various pipes above mentioned. By providing the numerous passageways as Just described, ample water is supplied at all times sov that ample steam maybe supplied for the outlet orifices 2|! when the iron is in use.
While I have illustrated and described what I believe to be a preferred embodiment of my invention, it is obvious that various changes might be made in the general form and arrangement of the parts without departing from the invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alteration as clearly fallwithin the spirit and scope of the appended claim.
I claim:
A pressing iron including a base having steam super-heatingchambers therein and having discharge orifices in the bottom of the iron leading from said super-heating chambers, a block .fixed on said base and having a front heating chamber and a rear heating chamber, said front and rear heating chambers extending substantially throughout said block in the same plane, a manually-operated valve controlling communication between said front heating chamber and said rear heating chamber, means having a water supply in liquid communication with one end and an opening into the 'front heating chamber at the other end, for supplying low quality steam to said front-heating chamber, said block and base having communicating passages therein connecting said rear heating chamber with the super-heating chambers in the base, and an electric heating element in the base below the block and serving to heat both the base and the block.
