I Application Maren '1,' im, .sulla v ligsiww TESjPAT Istant morale mom Anm naman This invention relates to electric` irons and morel particularly to .combination electric ironer and dampener for pressing and ironing clothes.

The main objects of this invention are to pro- J vide a combination electric ironer and dampener; to provide an article of the class described having a water reservoir attached to the iron and formf ing a part thereof; to provide a thermal insu-v lator which is located between the water reserl voir and the heating element; to vprovide an ironer and dampener having a circuitous groove in the shoe of the iron; to provide a conduit leading from the'reservoir; to provide a plate for covering the shoe of the iron; to provide a valve `mechanism forcontrolling the amount of water deposited in the groove; to provide a chamber having apertures extending outwardly therefrom; and to provide an ironer and dampener which will emit dry steam.

An illustrative embodiment of this invention is shown in the accompanying drawings, in which:

Figure lis a top plan view of the iron. Fig. 2 is a side view partly in section taken on the line 2-2 of Fig. 1. Y

Fig. 3 is a front view partly in section takenI on the line 3 3 of Fig. 2."

, Fig. 4 is a plan viewpartly in section taken on the line 4-4 of Fig. 2 and with parts broken away. Referring in detail to the construction shown 30 in the drawings, the electric iron comprises a shoe 1, a cwer plate 2, a handle 3, and a reservoir 4.

The shoe 1 is of special construction and is* provided with a circuitous groove 5 and a cham' ber 6. The chamber 6 is provided with apertures 7 extending outwardly therefrom to the face 8 of the shoe 1 and adjacent the toe 1'.

The handle 3 is of the usual construction and is heldin place by the brackets 9 and bolts 10.

The reservoir 4 is secured to the rear of the iron and over the heel 37 of the shoe 1 as shown in Figs. 1 and 2, and is provided with a water inlet 11 and an air vent 12. The reservoir 4 is constructed so that it requires a minimum amount of space on the iron and is not appreciably larger than the ordinary iron. With this in mind, I have constructed the rear medial portion of the reservoir 4 in a U-shape so as to accommodate the plug 13 which is attached to an electrical Supply source (not shown) through wires 14, to the contact elements 15 of the iron. A bracket 16 is secured to the reservoir 4 for setting the iron on end in the usual way when the iron is not in immediate use. A conduit 17 leads from the reservoir 4 to a valve mechanism which will be hereafter described. spiate-1s isfpiagd overtne snee 1 and forms a cover fortliegroove` 5. A continuous channel is thereby-formed. v`A heating element 19 4 'is then placed over the'cover plate and connected at one end to the contactelements 15` by a'con- 60 ductor 33. f The heatingjelement-does notextend under the reservoir. :An'.=insulating plate 20 is then placed over the heating( element and a holdthrough a linkage.

ing plate 21 is placed over the insulating platef i The plate 21 is then fastened to the shoe 1 by ay 465 suitable means, such as screws 22, etc. (See Fig. 4.) l

'I'he reservoir 4 is thermally insulated from the shoe 1 by providing a plurality of longitudinal apertures 23 between the lower portion of the 70 reservoir and above the heel 37 of the -shoe 1 s'o as to allow air to pass freely therethrough.

A valve mechanismis disposed adjacent. the front part of the iron and comprises a lever 25 which has a knob 24 attached to one end and a 75 needle rod 27 pivotally attached at the other end (See Fig. 3.) The lever 25 is pivoted as at 26 by any suitable means such as a bolt, etc.

The lower end of the rod 27 is conical shaped 80 and is adapted to nt snugly into aperture 28, and a' helical spring 29 normally tends to hold the rod 27,in closed position, as shown in Figs. 2 and 3.- A channel 30 connects the valve mechanism tconduit 17. I

In operation the reservoir 4 is filled with water and plug 13, attached to an electricsupply source, is connected to contacts 15, thereby delivering electrical energy to the heating unit 19. The water in the conduit 17 positioned adjacent the heat- 90 Y ing e1ement,will thereby be preheated. When dry steam is to be emitted from the shoe, the knob 24 is depressed, the preheated water in conduit 17, will be forced upwardly through the aperture 28 and downwardly through channel 31 and be de- 95 posited in the groove or channel 5, and the water instantaneously becomes steam, due to the high temperature of the shoe.

As the steam passes through the circuitous groove 5, it becomes superheated, andby the time 100 Experience has proved that in ironers and dampeners having the water reservoir attached to the iron, means must be provided to prevent the rapid formation of steam in the reservoir. Having this in mind applicant provides a thermal insulator, shown particularly in Figs. 2 and 4. which is adapted to provide l'or free air circulation beA tween .the reservoir and the heating element, and serves to retard the transmissionA of heat to the water in the reservoirA and keep thetemperature of the water below the boiling point.

Although but one specific embodiment of this invention is herein shown and described, it isfto be understood that some of the details as set forth may be altered or omitted without departing from the spirit of the invention as dened by the following claims.
