SELFJTIEZATING FLATJRON.

Specification of Letters Patent. Application filed March 25, 1911. 4

mosses.

To all whom it may, concern:

Be it known that We, lViLLIAM J. FRANCIS and CARRIE S. 'lAsoAn'r, both of Pittsburg, Allegheny county, State of Pennsylvama, have invented certain new and useful I111 proveinents in Seltlleuting Flat-lronspand We hereby declare that the following ise full, clear, and exact, description thereof, reterei'lce being had to the accompanying of this specification.

This ii'l'vention is :1 novel self-heating". flat iron to): laundry work; its object is to p1=0- vide a. flat iron which can be satisfactorily and properly heated by means of gas with out danger or inconvenience to the operator, and in which the *ill be fully consumed and the flame cannot come out the side of the tint iron so as to injure the operator or the goods ironed.

T he invention consists in the novel con struction oi the lint iron as hereinafter de scribed and as illustrated in the accompanyinn drawings, in which v Figure 1 2 side View of the iron. is an enlarged bottom View of the top portion oi the iron removed with the shield partly broken away. Fig. 3 is e plan View of the lower part'of the iron with the top portion removed. .F 4 is an enlarged sectional (lQ'W on line h el; Fig. 1.

The lint iron is composed of a lower bod portion 1, and a. top portion 2, Which togelluzr "term the body of the iron and are separable on a horizontal line. The body 1 is hollowed on its upper surface to form a clnunber i which is closed on all sides 0X- cept the rear, and it is provided with a number of :uvstandirg pins 1, preferably formed of steel wire which are secured in the body of the iron by being inserted in the mold and having the body 1 cast around them. These pins 1 some both to disseminote the mixture of gas and air entering the cbuniber l and to transmit. heat from the burning gases to the bottom of the iron. The top 2 of the iron is of novel construction, it is also hollow, but its top is imper torate end it is provided on its sides with depending; than which rest upon the top Fig. 2

edge of the body 1, and thus the hollow in the top-pert increases the area of the coun bustion chamber in the iron.

The flanges 2 at front of the top are imperforate so that there is no Patented Sept. 13, 191i. Serial No. 616,943.

outlet from the chamber 1" at the front of the iron; and the rear flange 2" is also ilnperforate, that there no escape for the gas at the rear of the co1nbustion chamber. At each side of the top 2, in terinedinte the front and rear tlangcs 2 2", is a. series of transverselydisposed depending flanges 2 which extend inward iii'ointhe outermost edge of the top to about onethird across the Width thereof, see F 2 and 4:; and the spaces between these transverse flanges 52 form pusflages 52 for the exit of the products of combustion.

Secured to the top 2 beneath flanges 2 and overlapping the inner ends of said flanges is a deflector 3 see Figs. 2 and 4, which may be soured to the top by means of bolts 3 transiifcing top 52, and the de tlector may be spaced from the underside of top 2 by means oit tubular washers 3 strung on bolts 3 shown. The bolts 3 may also .be used to attach the handle 4- to the top 2. This handle may be provided with a hand piece .43 of any suitable cm'istructiong and the handle may be provided with a heat d'eflector i" beneath thev hand-piece as shown. The deflector is provided on its sides with downwardly turned flanges 3" which contract the combustion space within the chamher 1 and prevent any llanie jetting outward through the outlets 2. The space below the deflector 3 terms the priunn'y coin-- bustion chamber of the iron above it constitutes an air interposed between the con'ibustion chamber and the handle. so that the principal heat of the iron will be confined to and within the lower part I Where it most necessary.

Preferably the iron is heated by and for this purpose a mine 5 of the usual type may be used. This mixer has ajnippl'e 5 that ihe be connected. by e l (not shown) to convenient The ]11lXGl.5 has :1 short tube 5 entering the rear end of the chamber l The mixer can e conveniently connected to the flat iron. by having the tube F engaging recesses 1 and f2 in the rear end flanges ot the body .1 and top 2 as shown.

The top piece 2 may be detachebly at tached to the body 1. by any suitable means, preferably by means of screws 2 passing through holes in the top and engaging threaded apertures in the body 1 as shown. The inner end of the tube 5 may be covered gas supply.

of the top? and the space cl-ieinber which is flexible hose with wire gauze 5, which may be secured thereto by a clamp ring 5 or other suitable means.

In using the flat iron gas and air are admitted through miXer 5, and ignited in the chamber 1*; the burning gases flow beneath the deflector 3 and are thoroughly commingled in passing through this chamber by the pins 1. The flame is practically confined within the body of the iron 1, below deflector 3, and the products of combustion flow to the other end of the iron and/eyed tually escape through the outlets. \Zi e have found that it is most essential t ol the successful operation of the iron, to have the transverse flanges 2 extend inward some.

distance to and above and o'ver the deflector 3. It will be seen that the combustion chamber is practically:entirely closed on all sides and in front. By havingthe top out out or hollowed in front of and above the deflector and provided with the transverse flanges,

' the gases are divided up and disseminated to the different outlets in their escape. The pecullar construction of the top with transverse flanges 2 and the deflector are essentialtfeatures of the flat iron; and with such construction the gas is fully-consumed and downwardly to confine the flame in the body' portion.

2. In a flat iron, the combination of a hollow body portion having a series of upstanding pins connected with its bottom, and a gas and air mixer connected with the body in rear of the pins; :1 top portion provided with front and rear depending flanges fitted on the -body portion, and a series of transversely disposed flanges on the underside of the top portion intermediate'the front and rear flangesthereof.

3. In a flat iron, the combination of a hollowbody portionhaving a series of upstand ing pins connected with its bottom, and a gas-and-air mixer connected with the body in rear of the pins, atop portion fitted on the body portion. and provided with opposite series of transversely disposed flanges on its underside; and a deflector plate secured to the top portion below the said flanges and 'depending--withinthe body portion and having its side edges bent' downwardly, substantially as described.

4. In a flat ll'Olh'tllG combination of a boll'ow bodypo'rtion having a series of upstanding pins connected with its bottom in casting, and a gas and air mixer connected with the body in rear of the pins; :1 top portion provided with front and rear depending imperforate flanges resting on'the body portion and a series of transversely disposed flanges on. the underside of the top portion intermediate the front and rear flanges thereof; and a deflector plate. secured to the top portion below the transverse flanges and depending within the body portion and having its side edges bent downwardly, sub"- stantially as described.

In testimony that, we claim the foregoing as our own, we allix our signatures in presence of two witnesses.
