Application mea August 17, 1912. serial N;71'5,563.

To all whom it may concern Be it known that I, HENRY W.V ODown, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have made certain new and useful Improvements in Sad-Irons, of which the following is a specification.

The vinvention relates to sad irons, and more particularly to that kind of sad iron which is heated by a gas burner contained in the iron. e

Objects of theinvention are to provide an improved device of the character referred to which', while simple and durable in construction, shall be highly eflicient and eco'- nomical and safe in operation.- Y

These and other objects of thei invention will in part be obvious vand in part more fully explained in the follovvingl description, f

Theinvention consists in the novel parts, improvements, combinations, lfeatlires of construction herein shown and` described lIn the accompanying drawings, which are referredto herein and form a' part hereof, is illustrated an embodiment of the invention, the same serving inconnection with the description hereiny to illustrate thepri'r'lci-4 ples of the invention. n

Of the drawings: Figure l is a perspective view of an embodiment ofthe invention; Fig. 2 is a vertical central section of the same, parts beingshown in perspective,t Fig. 3 isa perspective view of a detail; and Fig.

in perspective.

A sad iron constructed-.in accordance Withcertain features ofthe mventIoncom'prI-ses" in combination, a casing forming a chamber, a base having transverse'corrugations', a plurality of said corrugations being hollow to form air passages and having openings" in theirV upper portions to admit the air to said chamber, anda burner arranged longitudinally in said chamber and above said corrugations, said lburner. having perforations arranged therein to directfthel flame downwardbetween said corrugationsrf According to-other features of the invention, a plate Vis arranged at the bottom of said chamber and said plate iscorrugated, the yplate being castI with the' ridges* of the corrugations' hollow as` above set forth; the

sides and rear wall of theA casing'are formed with openings therein for'thevescape of the heated products of combustion, said open-,

ings being' of sufiicient capacity to set up a circulation; a hinged top is provided for the iron,V and an air-mixing tube is provided for the' burner.

VReferring now tothe drawings in detail, the embodiment of the invention illustrated comprises a casing 6 ofthe usual configurai tion and formingV achamber 7. Into this chamber is introduced through an orifice'8 in the rear wall o'f the casinga burner A9 ofl the Bunsen type, the air mixing tube 10 of which is arranged outsideof the casingand isl connected in la vusual manner 'with ther i p While the burner 9 may be arranged in the said chamflexiblev gas tube,4 not shown.

ber in a variety of .ways,preferably and as shown, it extendslongitudinally and cen trally ina horizontal' plane of the chamber,

bei-ng held in placefforward by a piece 12 fitting into a correspondinglyshaped recess in the front of the casing. The burner is supported also on lugs 13 and 14 of suitable height andsituated, respectively, at-the opposite ends ofthe chamber?, and to these lugs some further allusion will be 1made.-

4As shown, the burner V'Z' and mixing tube 10 are ljoined by afla'ngevl', suitably ree' cessed for that-purpose, said'ilange being suitably secured,vas by screw 17, at its top to the rear wall of the casing. 'Io` prevent y the heatingof the vmining tube 11,0 by the burner 9, preferably a gasket 18.0f suitableV i 1 insulating materiahfasasbestos, is disposedv between the rear "wall" ofthe casing and ythe flange 16. In order that the base of the said' ironi may be' heated to the best-advantage, the burner" 9', vpreferably and las shown, is formed with a plurality of perforations 19 in its under side,- to which further refer-v ence-.Will presently be made.

Means are providedy for supplying air to the burner 9 to maintaincombustion. This means comprises a plurality of air passages formed in` thebase ofV the" casing and ary ranged transversely vof the chamber 7 at suitableintervals and having` openingsvso A disposed'fas to supply at points adj acentvto i the perforations 19.- of the burner atmosv ph'eric airfconducted' through said passages;

WhileV these air'passages may be provided" in various ways,rp.referably^and asfshown, a

plate 20 conformingin outline tothe walls of the chamber 7 placedin' the bottom of said chamber, thesaid-lugs'l and; 14 which are formed on said plate serving not only as supports for the burner 9 but also to keep said plate in position. As shown, also, said plate 2O is corrugated transversely to form alternate turrows 22 and ridges, which latter are cast hollow to form the air passages 21, openings 23 being formedin the side walls of the casing G in register with the air passages 2l. The ridges also 'have suitable openings 25 in the center thereof, through which the atmospheric air enters the chamber 7. The perforations 19 hereinbefore referred to are so disposed on the under side of the burner 9 that their liames are directed into the furrows Q2 and the heat is thus imparted quickly and without waste to the bottom of the iron.

Suitable vents for the waste products of combustion are provided, the same, preferably and as shown, consisting of openings 27 formed in the upper side and rear Walls of the casing 6. 1t is to be noted that these openings are of sufficient extent to afford -a capacity equal to thek demands of the burner with its primary and secondary air supplies and thus maintain a proper circulation.

The casing is provided with a hinged top 29 which is suitably secured to the casing, as by means of hinges 30 and the thumb screw 32 which operates in registering openings in the top and casing and which projects inwardly over the said top, as shown in Fig. 2, and this holds said top in position. As also shown, a handle 33 is removably secured to the top 29, as by thumb screw 35, which operates in suitable recesses in the handleJ and top, lugs 36 and 37 being also provided on the handlevwhich tit in suitable recesses in the top 29 and thus'steady the handle.

1t will be seen that a sad iron constructed in accordance with the invention will carry out the objects of the invention, as heretofore set forth, and will possess other advantages which will be apparent to those skilled in the art.

The invention in its broader aspects is not limited to the precise construction shown and described, as many changes may be) made in the details thereoll without departing from the main principles of the invention or sacrificing its chief advantages.
