ROBERT B. KILLGOREQOF sHonrHILLs, New JERSEY, Assiouoit rro easiest sAs Inoiv 00., or rnrnannnrnra, PENNSYLVANIA, A ooRronA'rron or PENNSYLVANIA.

To all whom it may concern e v Be it known that I, Ronnn'r B. KILLooRn,

SELF-HEATING sAn-Isona citizen of the United States, and a resident of Short Hills, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Self-Heating Sad- Irons, of which the following is a specification. i a i i My invention relates to selfyheating sad irons in which gas ora similar fuel is the heat producing medium and has forits Ob", ject to construct an iron ofthis kind in a manner to secure a maximum of efficiency of my improved sadiron; Fig. 2 is ahorir with a minimumexpenditure of fuel. My invention willbe fullydescribed here- Reference is to be had to mg drawings in wh1ch a e F igure 1 1s a central longitudinal sect on the accompany zontal section thereof on the line 22 of In the drawings, 5 represents the hollow body of the iron which mayl beof any customary and well known shape and in the example shownis provided with a movable cover 6 pivotally connected to said body at the front end thereof as indicated at 7 is provided with shoulders 12 adapted to bear upon the cover 6 at opposite sides of the slot 8, when said levercextends transversely of said slot in the position illus trated in Figs. 1 and 3, and thus lock said cover against movement relatively to the body 5. A handle 13 of any suitable description for manipulating the iron and moving the cover is secured to said cover 6 for i11- stance by means of screws 14. The upper edges of the side walls and rear wall of the body 5 are cut away so that when the cover 6 is in its operative position, openings 15 and 16 are formed respectively at the sides and rear of said body for the purpose of promoting a circulation of air within said body and of permitting the products of combustionto readily escape. A, channel 17 is formed in the bottom 18 0f the body 5 so as The said cover 6 is provided at'its rear end with,

pendent recesses, said partitions inthe example shown being formed integral with e Specification of Letters Patent. Patented Oct, l I Application filed Noveniblflii, 1912. Seria1 l To.731,044. a v I ,ject acrosssaid chanueland dividcthe same i i i the bottom of'the body, although this is not absolutely necessary, it being, clearly apparent that said independent recessesmay be of any desired shape. Airinlets 20 extend? through thelbottom ls and have theirouter or inlet ends in communication with the at mosphereand their inner or outlet ends in connection with said channcl117 and below? the interior surface of the bottomYlS, the

drawingsillustrating a pair of inlets 20 con ncctedwith each recess ofsaid channel 17, this arrangement being only an instance and i not indispensable.

A burnericomprising a tube 21 extends through an opening in the rear wall of the body 5 and hasits forward end securedjin the Ifrontof said body in any suitable man ner, as for instance by screw-threading; This tube 21 is located above and in registry with the channel 17 and is provided with jet openings 22 directed toward thebottom 18 inoppositc directions as shown best in, Fig, 3 and further forms part of or is connected with a mixing tube 23 located exteriorly of said body and preferably extending at an angle to the vertical. The said mixing tube 23 is provided with the usual, air inlets 24and nipple 25,the latter for the accommodation of the customary flexible tube adapted for connection with a source of fuel supply.

When it is desired to use the iron, the said flexible tube is first connected therewithand, with the source of fuel supply after which the locking lever 10 is swung to a position parallel with the slot 8, in which condition,

the shoulders 12 have been raised owingto the cooperation of thethreaded stem ,9 and aperture 11 and have been moved out of engagement w1th sald cover. The cover 6 is now free to be swung to an openposition to body to ignite the fuel which ityis to :be 1 a understood now issues from the jetopenings 22 of the burner 21. Owing to the fact that these jet openings 22 are directed toward the bottom 18 in opposite directions the resulting flames will contact with the surface 5 thereof at opposite sides of the channel 17 and will quickly bring said bottom to the heated condition required. for use. same time, atmospheric air will enter through the air inlets 20 and will pass fromopposite sides into the various recesses com posingvv the. channel ,17 and will-thenpass through each flame so, as to bringabout. a

maximumandv perfectcombustion of:the

fuelissuing from said 'jet openings 22.: The

gPTOClllCtS of combustionwill pass out .of. the openings 15 and 16 at the .top of the body so that acontinuous and complete circulation is secured withinsaid body. D.ur ingthis.op-,

eration the. partitions 19. serve; to. conduct fuel.

It is to, be understood thatethe various parts of the iron itself as well-"as-the burner wemay be. of any general.construotionian'd that the illustrationis only an example of my im-; provementand. further. that the various changesvmay be .made therein within the scope of, theaclalms without departing from the spirit of my invention.

I claim:

1. A sad iron comprising a I hollow.- 1 body- Copier! "Ski-Si patent may-be obtained for five cents each, by addressing: the Commissioner-of Patents At the r having a solid bottom provided with air inlet channels extending transversely through 2. Agsad iron comprisin hollowbody having a solid bottom provlded with air in let channels extending transversely through said solid. bottom toward the center thereof and a row of independent recesses com-. inencing at the inner surface of said bottom and extendingdownwardly therein into conhection with said air inlet channels, said row of recesses being located along the longitufdinal median line of the body, and a burner adapted for connection'with a source offuel supply located-in said body in registry with itnd above said recesses, the space between said burner and the 1111161" surface of-said bottom. being entirely w free .--thr-oughout its length. r I v In testimony whereof I have hereunto set iny hand in the-presence of. two subscribing witnesses. v
