Application November 13, 1943, Serial No. 510,109
First, to provide a more simplified construction of sad iron of this class;
Second, to provide a structure of this class wherein the reservoir provides" a support for the handle, as well as a stand for the iron when -in upright and out of operating position;
Third, to provide a simple means of controlling the steam generated by the electric element in Athe iron;
Fourth, to provide a more, elcient distribution of the water in the iron relatively to the heatin element for producing steam;
Fifth, to provide a novel means of conducting steam from the reservoir yto the base of the iron;
Sixth, to provide a sad' iron of this class which is very simple and economical of construction, easy to operate, easy to regulate, eilicient in its action and which will not readily'deteriorate or get out of order. Y K
With these and other-objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, vreference being had to the accompanying drawings and to the characters of reference thereon which form part of this application in which:
Figure l is a top or plan view of my sad iron showing portions brokenv awaytorfacilitate the illustration; Fig. 2 is a side elevational view of the iron showing portions broken away and in section to facilitate the illustration; Fig. 3 is a sectional view takenV from the line 3--3 of Fig. 2; Fig. 4 is a. bottom view of the iron.; Fig. 5 is a fragmentary sectional view taken from the line 5-5 of Fig. 4; Fig. 6 is an enlarged sectional view of the valve 9 taken along the line-'3.-3of Fig. 2 and Fig. 7 is a sectional view taken from the line 'I'I of Fig. 6. f
Similar characters of reference refer to similar parts and portions throughout the several views of the drawings: Y
The iron body I, iron bodyrbase 2, reservoir 3, handle 4, heating element 5, heating element casing 6, steam generator and conductor 1, pressure lequalizing conductor 8, steam control valve 9. heat control I and electric Aconductorshieldll constitute the principal parts and portions of my sad iron.
`Ihe iron body Ibase 2 is substantially of conventional shape and form, as shown in the drawings, except that it is provided with a V-shaped groove formed of grooves 2a and 2b which join at point 2c near the front point of the base at the lower side. They are substantially semi-circular; as shown in Fig. 5 of the drawings. At the junction 2c is provided a small hole 2d, shown best in Fig. 2 of the drawings, which extends upwardly slightly above the bottom of the grooves 2a and 2b at the junction. Secured to the upper side of the base 2 is the iron body I which is substantially conventional in form and shape. Posi.. tioned on this :base I inwardly from the body a slight distance and spaced from the upper surface of said base is the heating element casing 6 which forms a space in which the heating element 5 is positioned in any conventional manner for heating the base 2. 'I'he body I is provided with an open portion centrally at its back side in which: is mounted the front side portion of the reservoir 3 which is shaped as shown best in Figs. 2 and 3 of the drawings and forms a portion of the handle and serves as a portion of a stand as well as a water reservoir. It is provided With a forwardly and upwardly inclined side portion 3a with a substantially horizontal bottom portion 3b with an extended stand portion 3c with a gradually reduced upwardly extend ng curved portion 3d and with a reduced annular portion 3e at its upper end, al1 as shown best in Fig. 2 of the drawings. This reduced portion 3e forms a support for the back portion of the handle 4, the handle 4 being `provided with a conforming annular recess 4a adapted to receive this reduced portion 3e. The handle is also provided with an opening 4b in which is'mounted a plug member 3f which is screw-threaded into a hole 3y in the upper end of the reduced portion 3e which provides a filler opening for the reservoir 3. The handle 4 is provided with an extended portion 4c which is slightly broadened as shown best in Fig. 1 of the draw` ings and hinged together with the stand member 3c which is also broadened as shown in Fig. 1 of the drawings and forms a stand for the iron when it is not in use. 'I'he front end o f the handle is provided with a curved portion conforming with the curved portion of the body I and is secured to the body I by means of a screw member 4d screw-threaded into a bushing 4e anchored in the front lower end of the handle 4, as shown best in Fig. 2 ofthe drawings. Positioned over the heating element casing B adjacent thereto so as to receive heat from the heating element 5 by conduction through the casing 5 is the steam gen.. erator and conductor 1, which is shaped as shown best in Fig. 3 of the drawings to provide length for heat conduction from the heating element y5 for reducing water from the reservoir 3 to steam for use for dampening the clothes. The one end 'Ia is positioned through the wall portion 3 3a of the reservoir 3 so as to receive water from the reservoir near its lower side and` this conductor is provided with a valve 8 for regulating the flow of the water,v which isa substantially tapered valve with openings providingV increased volume from the on position, the shape as shown best in Figs. 6 and 7 of the drawings. The valve' is positioned in a casing 9a with waterpassages Sb and 8c therein at opposite sides connected with the conductor 'I by means of packing bushings 9d and 9e, as shown best in Figs` 2 and 3'of the drawings. The opposite end ofthe conductor I from the end 'Ia connects with pressure equalizing con-A ductor 8 at 8a which is provided with an angularly positioned portion 8b which extends downwardly through a tubular portion 6a of the member 6 and into an opening 2e so that the tube communicates with the hole 2d inthe base 2, as shown best in Fig. 2. This conductor 8 extends upwardly then backwa-rdly through the body I above thel conductor 'I then into the handle 4 vand out through said handle portion 4 and extends into the reduced portion 3e of the reservoir. 3 and is provided with an extended end portion 8d, all as shown best in Fig. 2 of the drawings. The valveVv 9d is provided with a shaft portion Bf which extends upwardly through the body I and isrprovided on its upper end with an indicating handle portion 9e which operates in conjunction with an indicator positioned on' the upper face of the body I surrounding said shaft S, all as shown best in Fig. 1 of the drawings. -Positioned forwardly ofv this indicator 9e is another similar indicator I0 in connection with the conventional thermostat. The electrical conductors I2 for furnishing currents for the heating element 5 are positioned in electric conductor shields II which enters the body I at Ia and connects with the heating element 5 through a thermostat, not shown.
The operation of my sad iron is substantially as follows: The reservoir 3 is filled with water to near the bottom of the reduced portion 3 through the opening in which the plug 3g is mounted and with the plug repositioned the iron may be stood on its end supported on the portions 3c and 4c'inV which case no water would enter either of the conductors I or 8 to passtinto the iron. With the electricity turned on the heating element 6 would heat, heating the steam generator and conductor 1 and by turning the valve 9 to the proper position for the kind of clothes to be ironed water would pass from the reservoir through the portions 1a of the conductor 'I through the valve in regulated quantities into the conductor 'I where it is heated by conduction from the heating elementY 5, fillingv the conductor 8 in the space above'the water in the reservoir, then passing through the portion 8b to the hole 2d and outwardly onto thev goodsthrough thegrooves 2a and 2b andl dampening the goods while the iron is applied forV pressing,l it being noted that both the iron base as well as the ,quantity of water is regulated andas indicated. It will be noted that the sadiron is provided with automatic shut offs of the water as well as equalization of the pressure of the steam in the iron.
Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement, but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
Having thus described my invention, what I claim asnew and' desire V to secure by Letters Patent is:
