Be it known that I, ALi'iEiiT N'r0LA,'a citi- Zen of the United States, residing -at Newark, in the count'yof Essex and State of New Jersey, haveinverited certain new and useful Improvements in Smoothing 01'' Laundry Irons; and I do hereby declare the following to be a full, clear, and exact dethe invention, such as will enappertains to make and use the same, refer.- en'ce being had to the accompanying drawings, and to Characters -of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to

improvements in heating devices; and, the.

present invention relates, more'particular'lyto a novel smoothing or laundry iron, an I to an electrically heated iron and such details of improvements therein, as will hereinafter be more fully set forth.

especially The invention has for its principal object to provide a heating device, in the form of a smoothing or laundry iron, which will be very simple in its construction and of v few parts, and the heating elementof which isin such a manner within the chainarranged bered body of the iron so'tliat the heat which is generated by means of the said heating element is readily distributed to that portion or portions of the said body where it will produce the best results, and with the least expenditure of electric current;

The invention has for its'flirther object to provide a smoothing or laundry iron in which all of the parts are made so as to secure economy and facility in construction,

the parts being readily assembled, and just as quickly removed for repairs; and, whenassembled producing a rigid, strong and durable smoothing-or laundry iron.

The invention has forits further object to provide in connection with the electrical heating" element of the iron,- an automatically operating electric switch or current interrupter, by means of which when the iron is set upon end or upon its heel portion, the electric circuit is immediately interrupted,

so that there will be no consumption of the electric current when the iron is not in i158.

The invention also has fora-nether object I Specification or Letter-smear. Pate-magi J 11y2'9,191'3 Application filed Se tember 1 1911. "Serial No. 647,176.

- to provide in connection with the smoothing 'or laundry iron, means in thefor'ni of, and which may be used as, standards or support ing members, by means of which the iron can be suppcrte'd in its reversed position, so as to serve a heating device, forre'adily moving back and forth ever the heated flat surface ofiits body such articles, 'asnarrow ribbons, neck-ties, and the like, which are to be ironed out, or for using the said flat surface for other heatingpur oses.

Other objects 'Ofthis invention time more particularly enumerated will be clearly understood from the following detailed description of the present invention.

With the various objects of the present invention in view, the said invention consists,

primarily, in the novel smoothing or laundry iron hereinafter set forth; and, the in vention consists, furthermore, inthe novel arrangements and combinations of the various devices and parts, aswell as in the details of the construction 'of the said parts, all of which will be more fully described in the following specification and then finally" embodied in the clauses of the claim which I are appended toand which form a-n'essential part of the said specification.

The-invention is clearly illustrated in the accompanying drawings, in which Figure 1 is'a side elevation of a smoothing jor laundry iron made according to and embodying the principles of the present invention, representing the iron in the position not at this'h when it is being used for smoothing or ironing out arments, and the like; and Fig. '2

is a similar view of the iron, showing the same, however, set on end or upon its heel, so as to cause the automatically operating switch or current interrupter to interrlipt or break the electric circuit; .Fig. 3 is a vertical section ofthe iron,-

Fig. 4 is a plan or top view of the chambered main body of the iron and,

5 is a similar view of the said main body with its cover plate removed, showing within the chambered portion of the body, and in or laundry iron, said section being taken on line 6-6 in said Fig. 3, looking in the direction of the arrow m; Fig. 7 is a perspective view of the said heat-conducting or distributing plate or element; and Fig. 8 is a similar Viewof the supporting frame or core of the electrical heating element, with the electric wires removed therefrom. Fig. 9 is a detail longitudinal vertical section, taken on line 99 in said Fig. 1, looking in the direction of the arrow y, said view being made on a considerably enlarged scale.-

Similar characters of reference are employed in all of the above described views, to indicate corresponding parts.

In the said drawings, the reference-character 1 indicates the hollow or chambered main body of the smoothing or laundry iron, which may be of. any desirable thickness and marginal configuration, the same, however, being preferably made with the pointed toe-portion 2, the curved side-walls 3, and the rear wall or heel-portion 4. As shown in Figs. 3 and 5 of the drawings, the toe-portion 2. is made with .an ofi-set, as 5, and the side-walls 3 are not of the same thickness throughout, but are made of greater thickness at their middle portions and toward the heel-portion of the iron, being of least thickness at points near the toeportion 2 of the iron. The purpose of this is that the generated heat, after the electric current has been shut off when the iron is set upon end or upon its heel-portion, will be retained much longer in the thick partsof the said side-walls 3, and a radiation of the heat is consequently maintained in the directions toward the interior or chamber of the main body of the iron, and is taken up by the thin bottom 6 of the iron, so as to keep said bottom hot for some length of time, even after the electric current has been interrupted.

At a point near the rear end of the main body of the iron, said body is made with a laterally extending wall or partition 7 which is not quite as high as the side-walls 3, and whereby an auxiliary chamber, as 8, is provided, the bottom-portion 9 of which is preferably of greater thickness than the thin bottom 6 of the iron. Within the said chambered main body is a thin layer of suitable insulating material, as 10, such as mica, or the like, said insulating material bein arranged upon said bottom 6 and extending up the inner surfaces of the walls 3 of the said chamber, substantially as shown in Figs. 3 and 6 of the drawings. Arrranged upon this insulation is the heat-pro ducing element or unit, the same in this instance being in the form of a wire-resistance or coil, as 11, made from suitable wire which is wound in the form of a substan tially fiat coil upon an open frame-work or core 12, substantially of the configuration shown in the several figures of the drawings, and more especially in Fig. 8. This frame-work or core consists, essentially,of a pair of longitudinally extending members 13 and a pair of laterally extending con necting members 14:, all of which are made from suitable insulating material and are preferably integrally united, as will' be cleary evident from an inspection of said Fig. 8 of the drawings. As shown, the outer faces of the said members 13 are preferably serrated or provided with grooves, as 15, for the arrangement of and the proper winding of the wire upon said framework or core 12, and the said end or laterally extending connecting members 14 being of less thickness than the thickness of the said side or longitudinally extending members 13, for the purpose to be presently more fully specified. The general outline of the said supporting frame or core 12 and the windings of the wire-coil thereon are such that the heat-ing element thus produced will closely fit within the chambered portion of the main body of the iron, substantially in the manner represented in Figs. 3, 5 and 6 of the drawings. The heating element or coil 11 is suitably maintained in its proper position within the chambered body 1 of the iron, by means of a metal plate or bar16, preferably of the general, configuration shown in the drawings, the said plate or bar 16 being comparatively thin, so as to be a good conductor of heat, and having a somewhat enlarged head or end-portion 17 which is provided with a screw-receiving hole 18 for the reception of a screw 19, by means of which the said end-portion of the iron plate or bar 16 is secured upon the off-set portion 5 of said main body, substantially in the manner illustrated. As will be seen from Figs. 3 and 6 of the drawings, the main body of the iron plate or bar 16 when thus secured in place rests firmly upon the upper surfaces of the said cross or laterally extending members 14 of the supporting frame or core ably insulated from the said coil by means of a sheet 'of insulating material 27, such as mica, is connected with the post or screw 28 of one of a pair of switch- elements 29 and 30. The element 29 is provided with a contact-member 31, and the element 30 is provided with a contact-member 32. The other switch-element 30has attached to a binding post or screw 33 thereof, the leading-out wire 34 of the main circuit.

The manner-of completing an electric cir-.-

euit through the resistance or coil 11 is by means of a switch-lever 35, which is pivoted at- 36 and has a handle or finger-piece, as 37, by means of which it may be manually operated. if desired. -The said lever 35 is provided upon its under surface with a contactmaking member 38, see the dotted outline in. Fig. 4 of the drawings which when itmakes contact with both contact- members 31 and 32, as shown, establishes or completes an electric circuit through the said resistance or coil 11. Arranged above the said resistance or coil 11 is an insulating plate or sheet 39, of asbestos, or the like, and suitably disposed upon said jplate or sheet 39 is a metal closing plate 40, which is secured to the said main body 1 by means of screws 41,) said screws being screwed into screw-receiving holes 42 in the said side-walls 3 of said body. The said closing plate 40' is of the same marginal configuration as the -main body 1 of the iron, but is somewhat smaller than said body so as td expose a'port-ion of the toe and side-walls, andalso the heel-portion of said bod y, thereby forming a suitable rim for-the marginal edge of an outer hollow or chambored cover 43. This cover 43 is provided with suitably disposed holes or openings 44 which correspond vto the correspondingly located screw-threaded bosses or enlargements dry iron. The previously mentioned handle or finger-piece 37 of the switch-lever 35 extends through and is movably arranged in an opening 49 with which the said cover 43 is provided. The said cover 43 is also made with an open part, as, 50, which is closed by ineansof a blockor cover 51 of a suitable insulating material, andwhich is provided with perforations 52 through which the preriouslv mentioned main circuit wires may pass, substantially in the manner illustrated. Extending rearwardlyand upwardly from the rear wall-portion 53 of the said cover 43 are a pair of bracket-like members 54, and

'Ea'clrarm 56.is formedwith a rearwardly in'ogecting lug 58 and a' forwardly extending another post 62 which is formed with a hole said switch-lever -35.

'pivotally connected with said members 54, by means of screws 55, or in any other suitable manner, is a heel-support in the form of a frame which comprises a pair .of arms 56 and a connecting plate-like member 57. 76

lug 59, and when these partsrare in the positions shown in said Figs. 1, 2 and 3 of tlie drawings, the said yoke-shaped frame or heel-support serves as a means. for standing the smoothing or laundry ironupon its rear end, in the manner illustrated in said. Fig. 2

of the drawings.

In order to interrupt the electric circuit,

when'the iron is placed upon its end, in the 63'of' an angular conformation, said hole 63 also forming a bearing-portion.

Slidably arranged in the circular hole 61 of the post 60 is the end-portion of a screwthreaded shank 64 with which is connected a stem 65 of angular cross-section, corresponding to that of the hole'63 in the post 62, said stein being slidably arranged in said hole 63, but on account of the angular cross- 10o section of the said stem 64 and the angular conformation of the hole 63, said stem and said shank are non-rotatably mounted in the said bearing portion's of the-respective posts. The said stem 65 extends through a slot or elongated opening 66 in therear or endwall of the cover 43-, having suitably screwed and adjustablv arranged. upon another screw-threaded shank 67 which is connected with the stem 65, a knob or en largement, as 68. Encircling the said stem 65, between the said rear or end wall 53 and the said knob 68, is a coiled spring 69, the tendency of the said spring being to normally move the parts in the direction of the 11s arrow .2 insaid Fig. 9. The adjustable arrangement of the said knob or enlargement a 68 permits of the proper regulation or adjustment of'these parts, as will be clearly evident. Suitably connected with the said. 12. switch-lever 35 and extending downwardly therefrom is a member 70, said member having an internally screw-threaded part'Tl .into-which the screw-threaded shank 64 is screwed and is adjusted with relation to the The previously mentioned. cont'acbmaking member is also connected with the said hank'64 by means of a hub-portion 72 which is insulated from the said shank 64 by means of a sleeve 73 of a suitable insulating materiahes shown in said Fig, 9, the parts being retained in their adjusted relations by means of s nut 7d, sub- 69 becomes compressed, and the angular-stem ltd turned into in the dotted outlines in said Fig. l eithedrawings,

placed in a reversed position,

of a small heater,

- and screw-threaded shank'fid will move in s direction opposite to that indicated by the arrow 2, whereby the contact-melting member '38 is moved rom its electricsl contact-with the contact-member 32, so that the electric circuit through the resistance or coil 11 is immedietely broken or interrupted, As soon as the iron is agein taken up end used upon a garment, the said spring 68 ceuses the parts to again assume their normal initial positions so that the member 38 again ridges the two contact-members 31 end 32, and a complete electric circuit-through the resistance or coil is immediately produced, its will be clearly evident. 1

At one end of the handle of the smoothing or laundr viron. is a, reversible plate which, wit'i the previously mentioned yokeshaped frame or heel-support, may be the reversed positions indicated and whereby the iron may be with the electric current turned on, so that the heated body-portion 1 may be used in the menner or for the purpose of smoothing out nsrrow' ribbons, necleties, end the like.

I am aware that some changes may be made in the general arrangements and combinetions of the various devices and parts, as well as in the details of the construction of the said parts, without departing from the scope of the present invention, as set forth in the foregoing specification, and as defined in the clauses of the claim which are appended thereto.
