UNITED STATES PATENT OFFICE.

BARNETT WRIGHT MACY, 0F JACKSONVILLE, FLORIDA, ASSIGNOR TO ELECTRIC HEAT- ING CORPORATION, OF JACKSONVILLE, FLORIDA, A CORPORATION OF FLORIDA.

GARMENT IRONER.

Application filed January 21, 1922. Serial No. 530,902.

To all whom it may concern:

Be it known that I, BAnNE'rr Wruerrr MACY, a citizen of the United States, residing at Jacksonville, in the county of Duval and State of Florida, have invented certain v stored and communicated to the ironing surface by an insulating liquid, such as 011.

Referring to the accompanying drawings which are made a art hereof and on which similar reference 0 aracters indicate similar parts,

Figure 1 shows a side elevation of a type of ironer to which my invent-ion may be applied,

Figure 2 is a vertical longitudinal section therethrough, and v Figure 3 is a section on line 33 of Figure 2.

The ironer illustrated consists of an elongated hollow member 1 forming an outer wall and having an oval or elliptical cross section, said member tapering gently towards its outer end. It is supported at an inclination of about forty-five degrees, by an iron casting consisting of a plate 2 bolted to a suitable support, an angularly extending pillar 3, and an oval plate 4, to which the hollow structure is screwed, a suitable gasket 5 being interposed to make a hermetically tight joint.

A porcelain tube'6 is supported axially of the structure 1, as by having the lower end of a core rod 7 screwed centrally in the plate 4. Supported on the porcelain tube is a resistance element 8, consisting of a small diameter coil of bareresistanw wire wound spirally on said tube and having end connections to terminal posts 9 projecting through insulating bushings in plate 4.

The structure 1 ma be formed of any suitable material, but prefer to use aluminum, on account of its lightness, good thermal conductivity and resistivity against oxidation. Any suitable insulating liquid may be employed to store the electrically generated heat and distribute it equally to all parts of the wall of the structure 1, but I prefer to employ for this purpose an oil having a high flashing point to prevent earbonization and eliminate vaporization.

Gas pressure in the upper part of the ironer may be relieved through a pipe 10, open at its upper end and connected at its lower end with an exterior tap 11.

An ironer such as I have described above will be found very clean and eflicient in use. Having been properly filled with oil or other suitable liquid, it can be continuously operated for long periods without requiring any attention. A suitable tap may be proyided for introducing the oil or withdrawmg it, in case repairs become necessary and the ironer has to be disassembled.

lVhile I have described my invention with particularity, I do not intend thereby to limit the said invention, as various changes can be made in the described structure without departing from the spirit thereof.

Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:

1. A garment ironer comprising an iron base, an elongated hollow aluminum ironing devlce mounted on said base in inclined position, a body of liquid therein, an insulatlng rod supported axially in said ironer, a resistance coil wound on said rod, insulating bushings in said base, terminal sts in said bushings connected respective y with the ends of said coil, and an open ended pipe projecting through said base and extending into said ironer to a point adjacent the upper end thereof, said pipe having a tap screwed in its lower end, substantially as set forth:

2. A garment ironer, comprising an elongated hollow metallic ironing device adapted to be filled with oil or other suit-able heat-distributing means, an insulating rod supported axially therein, a resistance coil of bare wire wound on said rod, insulating bushings in the base of said metallic structure, terminal posts in said bushings, and connections between said posts and the ends of said coil, substantially as set forth.

3. A garment ironer comprising an elongated hollow structure a body of liquid therein means for hermetically sealing the structure, a resistance coil extending axially of said structure, and means for connecting said coil with a source of electricity, substantially as set forth.

4. A garment ironer comprising a hollow elongated ironing element approximately elliptical in section and adapted to contain a li uid, an oval plate closing the open end of sald element, a gasket between the element and the plate, a resistance coil supported centrally of said element, and means for con necting said coil with a source of electricity, substantially as set forth.

5. A garment ironer comprising a hollow heat-conducting structure forming an outer wall, a body of liquid therein, a resistance coil supported in said structure and spaced from the wall by the liquid, and means for connecting said coil with a source of electricity, substantially as set forth.

6. A garment ironer comprising a hollow heat-conducting structure forming an outer wall,- a body of liquid therein, a resistance coil supported in said structure and spaced from the wall by the liquid, means for connecting said coil with a source of electricity, and means for withdrawing va rized liquid from said device, substantially as set forth.

7 A garment ironer comprising a hollow structure, a body of liquid within the structure and a resistance coil within the structure and surrounded by the said body of li uid, substantially as set forth.

n witness whereof, I have hereunto set my hand and seal at Jacksonville, Florida, this tenth (lay of November, A. D. nineteen hundred and twenty-one.
