i `Ber it known that I, `Fnnnrrnirn) M.` EUf GENnBLAss, acitizenof the German Republic, residingfat East: Oran e,.in. thecounty of Essex wand-State of ewT Jersey, have invented certain newiand usefullrnprovements in Self-Heating .Smoothingdrons, of whichthe `following isa specication. l This invention relates to improvementsV in` laundry dressinakersand Alike appliances, Y made from. suitable lmaterial collectively knownas said, orat irons,hereafter briefly called, iron, `adapted for manual operation insmoothing and pressingfthe surface of textile yon similar articles of personal and i domesticuse.` i Y The principal object is to provide `an irnplement of this character, having a `conventionally shapedaexterior: and operated 1n the usual manner, but` combinedlwith` an effective heatingpmeans and divided inte- `riorlyinto compartments through which theV heat is caused to pass` sinuously, thereby conserving and i. utilizing it to, thefullest.A ex-i tent` possible, byfreducing:lesstof heatby waste .and radiation.

Fig. 12 shows the last modification `with the i shutterg-down after the `heater is removed.

Fig. 13 shows this modiiicationas an elevationalrview of Fig. 12, and

. Fig. 14 shows thisk modification as an eleonly one burner The apparatusA comprises a handle 15, mounted in a supporting frame 16, curved and bentso as to present a `horizontally disposed part`= 17, "substantially parallel with thewaxisof the handle,fand secured by bolts or screwsylS tothe iron' proper, which, as

`indicated,"is ofthe conventional form and 4arlrangedwith a `:number Aof, partitions, dividing the'interior into aplurality of compartments whereby the heat is delivered and causedto circulate so to avoid'loss.

In Fig.` V1 is` shown a preferred embodiment-in which gas enters by means of; the tubes; 20, passes `through the` mixer 21, where `itis regulated by the adjusting screw 22 aproper admissionof the air and gas `beingprovided for by the perforated annullus 23T, the combined air and gasbeing ignited-,attheV endof the curved burner 24,

whereit enters the lower central compartment-ofthe iron. The"` burner is secured ima known manner `againstthe back-flare of the burning-` gas. i y

rlhe` burner i isipreferably arranged ywith two outlets,.and4` has va neck "25, and is pr`0- videdrwith `a suitable connection 26 adapted toengage gwith an upturnedprojection 27 providedon the `rearpl'ate 30 of the iron, the ...same `being heldin placen normally by means of the .projections 29 on the shutters 28.;- .'llherearplate 30 is provided with holes 31 for the; burner outlets 24:,with the outlets for waste gases-82. and theinspection opening 3,3 which? isdclosed `bya swinging cover` '311;` The solid part of the rear plate 30 lbeing adapted p l toigclo'sefthe rear openingsifofvtheiron com- .a patiemment; helas Stand-.3a willihe-lqsd ioo automatically bv means of the shiitters 28, which are arranged to swing on the screws 41 engaging with the rear plateA 30. It is also possible to'connect the waste gas outlet holes 32 with a tube to lead the waste gas to l a chimneyv or the like. Y

In the form shown in Figs. 1, 2, 3, 9 and 10 preferably a divided burner is used, the

heat from which enters the central lower compartment 35, passing upwardly at the compartments its full effect is obtained and Aao that the loss by radiation of heat is reduced to a minimum. It will also be seen that the greatest degree of heat is delivered into the lower ory heating compartment 35 directly over the `smoothing portion of the iron,` while theside and top compartments which almost entirely surround the heating compartmentV act as heat retaining compartments. I

The openings 32 allow for the proper disposition of the gases in such manner as to least aii'ect the operator, while the iron gets the full benet of the gas consumed.

In the modifications shownV in Figs. 5, 11,

' 12, 13 and 14, theburner is not divided, and

has only one outlet which is adapted to engage the burner inlet 31, and one waste gas outlet 32, both openings being covered when the burner is removed by means of a-'swinging plate 28, connected with the rear plate of the iron by screws 41 in. Fig. 5.V In this modification a shutter plate 28 is shown closed and having no opening for the 'waste gas outlet shown in Figs. 3, 11, 12, and 14, although this may also be provided if desired. The position of the plate when the burner is in position is indicated by a broken line, while the broken line indicating the plate in Fig. 3 shows the same in its position when the burnerv is removed,tlie inspectionopening 33 being shown asA covered with a swinging cover 34. v Avsimilar adaptation Jfor the heater with only one burner outlet is shown in Figs. 11, 12, 13 and'14,

' in which the shutter 2 8is shown as a plate sliding in slideways 42 and closing the openings 31 and 32 automatically when the heater is removed, and is'also adapted to hold the heater in position by means oi a hook 26 providedon the heatergan'd lip 27 provided on the shutter A28 tached to theiron.

1F igs'. and Sjindi'cate modifications oi construction, showing different arrangements of compartments, and the direction of the heat currents therein. Many other modi tications with two or more compartments are possible.

F ig. 4 shows a modilication in which instead ot using a heater with natural or artilicial gas, a known arrangement for gasiiying 'luids is used, which is connected with the fiat iron rear plate by the same means and with the shutter and holder hereinbefore described. It will be obvious that the same hat iron canV be used with a burner for gas,

or with a burner for gasifying fluids, which latter is inclosed in a bulb or container 43 as indicated in Fig. 4, and which contains all necessary means for regulating the control ot the liquid, its gasiifying and the admission oi air to miX with and burn the liquid gas.

From the foregoing it will be seen that a scientically arranged iron has been presented', which may be used with either gas orV gasiiying fluids with equal facility, and in which the heat is fully conserved before the waste gas is 'released into the atmosphere. l

Having thus described my invention and set forth its application and use, what I claim as new and desire to secure by Letters Patent, is
