To all ifi/mnt t may ammira lie it known that i, Santini', ioiliooii., a, eitixen ot the 'United States, residing at Zanesville, in the eounty oi lllusltingum and State oi: Ohioa have invented certain new and ilseilul l'mprorements in lilat-lronsa olf' which the 'Following is a sinirfzilieation.

My invention relates to fiat. irons and has particular reference to an apparatus of this character provided with means for `generating steam and properly applying' the same to the garment, or other article being?r pressed. i

in importantobject of this invention is to provide a tlat iron ot the above mentioned clnnaeter1 the parts oli the slam boiler and gas burner being' entirely dispos-ed within the shell or hotly portion o'l` the iron, and arranged therein in a eoinpziel manner so that the same will oeeupy the minimum amount ot spaee and the maximum amount oit steam generated hy the operation of the burner.

A. 'further object ot this invention is to provide a flat iron olE the above mentioned character, which is simple in construction, cheap to mannit'aetin'e` strong' and durable.

lOther objects and advantages otl this invention will be apparent during the eonrse oit the following' description.

iin the aeeompanying drawings lljormingappart of this specification and in whieh like numerals are employed to.` designate like parts tln'ougrhout the same, Figure 'l is a plan View of the steam boiler included in the iron, the top plate and burner being` removed, 2 is a central vertical lonnitudinal sectional view through the iron, lliigr. 3 is a transverse sectional view taken on line 3-3 of Fig. 2, and, Fig. 4: is a horizontal sectional view taken on line 4-l or Fig'. 2.

ln the drawings, wherein for the purpose of illustration, I have shown a preferred embodiment of my invention, the numeral 5 designates the body portion of the iron, which is preferably formed of a copper casting. The upper end of this body portion is 'formed open and is normally elosed by a t'op plate G, preferably formed ot' cast iron. At its upper end the body portion 5 is provided with relatively large openings 5, through which pass the tproduets of combustion from a burner to be described. The burner is also lit by inserting a match through one of thesev openings. A strip or sheet, ol1v asheslos l or other heal rr; l lerial in internobetween the pluie ll and duf body portion this-in p brine' held iofrellier lof store bolts or soi (d. as shown. l'onuirtrd with the top l" ll are upsllainliinf arms lll, earryinif al t upper ends :i handle llh whit-h is pret'ifrnl tor-med ol wool "lhe lower side ol? bodyr portion 5 h1 in the iorm ol a platt` provided with longitudiiml and li'aiisv l, passages or hores l and lil. These p: sages interi-:rail and are thereby plat-ei l'roe eonununiealion. "lhrl outer ends oi tli passages are tiri-enelhi'iaded, 'or rerriringr plugs ld.

Dis-:pof--zed upon the outer surface ol" tsm plaie ll is a isoley plaie iii, eonneelid there with by any suitable iiieans. 'lhis sole plate has ils rnirapjingf surt'are perl rily llat so that :lll portions thereol are (llisposei in ihr same plane, the saine heinir smooth or polii-lhed. this solo plate is prelrrahly *Formed ot` Arood elose irrained gray rast iron, whirh will linish well and wear smooth. filler the .vole plato has heen eon neeter'l willi the plate l I.; strani outlet ports 'lll are drilled lhroiurh the plate l5 and into the plate l l and lead into the transverse paS sages lil. lt has heen loiurd by experience that these outlet ports must he comparativelv small in diameter, the most satislaetory resultsl heine' obtainable by haring them n/illhs ot an ineh indiameleV. rlhese steam outlet ports are preferably trans versely spat-ed /loths ot an ineh apart.

This eoiled pipe is preferably a copper pipe havingf au internal diameter ot i/tth ot an ineh. The, upper and lower lnrns l?) and Q0 are disposed in dill'erent horizontal planes and extendlongitudinally within the body portion 5, as shown.- rlhe 'free end olf the lower turn 20 is serew-lhreaded, as shown at Q1, for connection with a water supply hose or the like (not shown). vThe innermost upper turn'lf) is eentrally arranged within the body portion 5 and is bent at a righty anfgle to 'Form a depending portion 22, havingr its lower end provided with an outwardly el\:I tending; ll'lanpge J3. This lower flanged end o't' the depeni'linir portion 22 is mounted Within an apertured upstanding boss 2li formed upon the plate 11. This boss 24 is Cil with a clamping nut 25, the lower end of which engages the flange 23, to securely hold the same in place and form a steam-tight connection. If necessary, a packing ring 26 may be interposed between the flange 23 and the wall at the bottom of the aperture in the` boss 24. The depending portion 22 has free communication with the central longitudinal passage 12 and hence with all of the passages 13, through the medium of a port or opening 27.

Mounted within t-he 'lower portion of the body portion below the boiler or steam generator 18 is an open tubular burner 28 preferably of'- the shape shown. This open tubular burner 28 receives therethrough the depending portion 22 of the steam supply pipe. This generator' is adapted to use gas as a fuel, either natural or artificial "gas or other fuel. The outer end29 of the burner 28 extends through an openingin the end wall of the body portion 5 and is connected wit-l1 a4 fuel supply pipe (not shown) through the medium of a coupling 30. As more clearly'shown in Figsf2 and 3, the burner 28 (which is in the form of a pipe) is'provided with openings or

perforations

31, 32,33, 34, 35, and 36, as shown. These openings are preferably made 1/16th of an inch in diameter. The openings 34 Yand 3 5; are preferably arranged at an angle of 45 with relation to the plate 11 and the opening 36' is perpendicular with relation p' .ii-hereto. The function in this angular arrangement of the

openings

34, 35 and 36 is to direct the llame so that the same will, properly fimpinge against the plate 11 to heat the'samef The opening 33 is disposed at anQ-anigleof 45 to the horizontal, the openinglis perpendicular to the horizon-k" tal. and'theopening 32.-is disposed' at an" angle'of '609,110 the'horizontal. I have found by this angular arrangement of the openings 31, 32 and33, that the flame passing therethrough will impinge against 0r heat the lower` turns 20 of the boiler 18 in a most Ivefiicient manner.

. The operation of the iron is as follows: The water is continuously supplied to t-he lower turns 20- of the boiler 18 from the hose or pipe v(no'tshown). This hose or pipe is provided with a check valve -for preventingthe back ow of the water'- or steam.

erated in the lower turns 20, the same will pass upwardly into the upper turns 19 within which the steam is further heated,

prior to its pasagc through' the depending portion 22. This steam n ow passes through the depending portion 22 and discharges into the

passages

12 and 13. In these passages the steam is further heated or superheated, while the same is discharging through the outlet ports 16. The object in providing the plate 11 with the

passages

12 and 13 instead of' having an integral open space or chamber formed therein, is to lessen the heating area which is engaged by the steam therein. It is obvious that the gas burner will provide flames which extend upwardly and downwardly at the. proper angles to efficiently heat the boiler 18 and the plate 11.

It is tobe understood that the form ofy my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes in the shape, size and arrangement of parts may be re-v sorted to without departing from the spirit of the invention or the scope of the subjoined claim. Havingthus fully described my invention, I claim .v In a flat iron of the character described, a bodyv portion including a lower plate pro videdwith communicating longitudinal and transverse.v steam receiving passages which dischargev through steam outlet ports, a

boiler .mountedwithin the upper portion of the body-.portion and formed of a coiled pipejintcludinglower intake turnsand upper steam -generating .turns having their discharge/end bent downwardly 4for forming a 'depending 'portion having communication '-,lwith'the longitudinal and transverse steam receiving passages, and an open tubular burner mounted within the body portion bef tween the boiler 'and lowr plate and reeeiving therethrough the depending portion, v of theboiler and provided with perforations upon its, upper. and lower sides.

'In testimony whereof I afiX my signature in presence of two witnesses.
