IRON;

Application led April 4,` 1925. Serial No. 20,794. K,

The yinvention relates ftoimprovements in an iron of the type adapted to receive -a solid fuel to be consumed therein during the use of theiron to generate heat.

It is -an object of the invention to provide escaping heated gases from the top. of the iron are controlled bya suitable damper and are deflected so asto be always maintained out of contact with the hands ofthe user.

Among other objects. the invention embodies an iron by means of which the solid fuel undergoing combustiontherein Acannot escape during the ruse'of the iron 'through' the airopenings;` to provide an iron withV anr improved form of base to facilitate the com-. bustion of Athefuel;,to provide an iron with., a base lto conduct Athe heat t'o the vgpoint of the iron where the highest temperature is desired.

In the drawingsi 'Figure' 1 is a -topplanfview of the iron assembled,

Fig. 2 is a vertical longitudinal sectional view of the iron,

Fig. 3 is a transverse vertical sectional view7 Fig. 4 is a fragmentary vertical sectional view showing in detail a portion of the draft producing structure,y

Fig. 5 is a horizontal sectional view clearly illustrating the bottom of the iron, and

Fig. 6 is a bottom plan view of the iron cover.

Referring now more particularly to the drawings wherein like reference characters indicate corresponding parts, the numeral l designates the body of the iron having the i base 2 which is of the usual shape. The base and the side Walls formingy the body are( preferably made from an integral casting of metal, the interior of the body being hollow to provide the opening 3 therein.l

The iron disclosed in this application is intended to burn av solid fuel such las. chars coal, coke, or any of the other well known The inventiony furthermore aims to prof vide Van liron-'of thischaracter in which the fuels useful for this purpose. Such'fe'l is placed Within the fuel receiving openingf in the interior of thefbody.' Means must be provided to cause a constant and proper consumpt'ion of this fuel inOrder-fthat sufli'cient heatbe generated to properlyheatfthe base of the iron. I provide at'theforward part of the iron at one side an openingl preferably semi-circular and leading into-anair feeding and deflect'ing tubular member 5for` directing the yair downwardly toward the base of the iron. This member has anove'rhanging shoulder 6 extending` well within the opening inthe iron forthe purpose ofk preventing. fuel from jarringV out ofthe* opening 4 during thereciprocationy ofthe iron. Acontrolling valve 7 is pivotedinto thek iron by means of.' which the diameter of the air feeding opening'fmayfbe .varied at will. n

The opposite side of the iron :near the rear vthereof is provided with asimilar opening 8. This opening leads to' the tubular vair "passageway 9' of the same:y structure as 4-here'tof fore described in discus'singfthe vtubularairv passageway 5. The overhanging ypor outstanding ledge 97 isalso providedfto prevent the jarring Yof fuel through 'this opening when the iron is in use.V The rotatable closure ,capY 10 I'is ,employe/d forv .controllingH this opening 'by means 'of' which the" draft can be varied. It will be understood that the tubular air conducting passages 5 and 9 are formed by casting integrally with the sides of the wall inwardly and downwardly extending walls being, of course, spaced from the bottom of the iron body. Itwill be understood that by arranging the air feeding openings in this manner, that is one at the forward part of the iron at one side and the other at the rear of the ironat the opposite side there is a constant circulation of air throughthe iron during its reciprocation. v

The-base of the iron is furthermore pro` in the base of the iron furthermore constispring 21 riveted `to this strap so that when l5 the top is to be applied it is only necessary tomove inwardly the finger member 19 and to then insertthe forward tip 15 of the slot into the socket 16, By yreleasing the finger member 19 the detent then drops under an 20 inwardlypextending catch 22 and the top is then detachably held in place. It will be seen that the top is provided with a pair of" circular openings 22 disposedon each side thereof. These openings are controlled by a` 25 plate 23 secured to apin 24C extending through the top, which pin at its outer end receives a lever 25;. The plate is provided With openings 26 of the same configuration as the openings 22 in the top of the iron,

30 and by rotating the handle 25 the openings` Vin the plate. and the top may be brought into or out of alignment, thereby controlling the draft in the iron. A spring 29 mounted on the supporting pin for the controlling plate urgessaid plate upwardly so that it frictionally retains itselflin any position of adjustment.- A i It is apparent that theissuing gases from the iron should not come in contact with the 40 hand .of the user grasping the handle 30 connected with the handle carrying strap 20.

To this end a false cover 31 is provided, the same being secured to the top of the iron at its center by means of rivets 32 while the ends of the false cover are raised or spaced from the cover for detlectnig the gases outwardly at the side of the iron.

It will thus be seen that when the iron is in use the removable top can be taken from the base of the iron by shifting the finger plug 19. Any desired solid fuel can then lbe placed in the iron. The dampers controlling the openings 4 and 8 in the side of the iron are regulated so that the required amount of air passes through the fuel in the iron during its reciprocation. The damper in the top of the iron isalso regulated' by the operation of the handle "25 serving to control the discharge ofexhaust gases from the iron and thesel gases pass out under the dei-lector rplate separated at each of its f'sides from the iron top. The variousclosures for theV gas and gas openings can be set to permitany regulated quantities of air or gas to pass therethrough in this way affording a veryV positive -control for the combustion of the fuel in the iron.

Having thus described my invention, what Iclaimfis:

In a sad iron, in combination a base and a body having Walls, said body being adapted to receive a solid fuel,`a` tubular air conducting duct leading from each side wall of the body and extending inwardly and downwardly toward the base thereof, the lower Wall of the duct constituting an overhanging ledge for` preventing the ldischarge of fuel through said duct, and valves for controlling said air openings.

In testimony whereof afiiX my signature.

HOWARD n.l CHAPMAN.
