This body casting 6 has removably secured thereto the handle portion which is designated in its entirety bythe numeral 7 By referring to Fig. 8,. it will be seen that this bottom casting 5 is provided with a plurality of fins 8 which are formed integrally therewith and cooperate with the longitudinally extending rib 9 forforming the flame pockets 10. The marginal edge of this flange 11 that is cutaway or notched at 12 for forming air inlets for the flame pockets 10. The rear end of this casting 5 is' provided with an upstanding ear 13 which is apertured at 14 and is internally screw-threaded for receiving the screw 15 that is employed for the body castingV to the bottom casting. The longitudinally? extending rib `9 is provided with an upstanding boss 16 adjacent the front end of the bottom casting 5 and this boss 16 has an internally threaded bore 17 for receiving the screw 18 which 4is employed for separately connecting the front ends ofthe body and bottom castings 5 and 6 respectively.

By referring to Figs. 9 to 12 inclusive, it will be seen that the body casting of 'the iron is of shell yformation and includes the side walls 19, the rear end wall 20 and the pointed front end 21. This front end 21 is formed with an overhanging wall 22 which Vis positioned substantially between the top hanging wall 22 and the top edge ofthe cast'- ing is provided with a vertically extending bore 24 formed in a boss 25. This bore 24 is reduced in diameter at its lower end 24u for 'forming a shoulder tor the reception of the connecting bolt 1S, best illustrated in Fig. 5. In Fig. 10, the casing 6 is illustrated as having the cored enlargements26 termed with the side walls oi" the pointed iront end 2l and located inwardly of lthe castings 6. These enlargements 26 are cored out and provided with burner openings 27 which provide :tor uniformly heating the liront end of the iron with respect to the remaining portion of the same. The tubular burner elements 28 are illustrated as having their front ends received within the cored portions 26 of the cored enlargements 26 and are arranged with their burner openings 29 presented to the flame pockets li) in the bottom casting 5. In Figs. 10, ll and l2 the rear end wall 2O of this casting 6 is illustrated as being formed with the tubular bosses 30 which receive the rear ends of the burner tubes 28 which are closed by the caps 3l held in place by the screws Ain F ig. 9, the top edge ot the side walls l) are illustrated as being provided witl tie notches 33 for permitting the entrance ot air into the interior of the body casting 6. By referring to Figs. 5 and 9, it will be seerrthat the cored enlargements are provided with vertically extending passageways 34 which are open at their upper ends and communicate with the said cored enlargements 26 at their lower ends. The side walls 19 oi this body casting 6 are provided with air inlets 36 which communicate with the passages 34, as best illus* trated in F ig. 5.v

Referring to Figs. A1 to 3 inclusive, it will be seen that a tank 37 is 'provid-ed which has a removable liller cap 38 carried by the neck 39 of the tank by means of which denatured or industrial alcohol may be placed within the tank. Depending :trom vhe lower wall of this tank is a feed tube 40 which coinmunicates with the lower portieri ot a substantially U-shaped 'converter trap coupling 41. Connected to the inner side' taces ot' the upperends of this U-shaped converter trap coupling 4l are the converter tubes 42 which extend longitnjdinally`T 'oit the body casting 6 and are arranged in parallelism with each other. The front Vends oi these converter' tubes 42 are threadedly connected with the valve blocks 43 which are provided with a connecting plate 44 which is secured to said blocks by the elements Thisconnecting plate 44 is apertured at 46 tor receiving the cap screw 47 illustrated in Figs. l and 5 as being employed tor aiding in connecting the handle portion 7 ot the iron to the body casting 6, the said cap screw 47 being threadedly connected at its lower end to the bore 24 of the boss 255 lformed integrally with the body casting 6.

4heat detlecting plate 58.

The construction of the valve blocks 43 is best illustrated in Figs. 5 to 7 inclusive. It will be seen that each block is provided with a tubular recess 47 within which the end of one converter tube 42 is received. Extending in axial alinement with this tubular recess 47 is a reduced passageway 4S having a valve seat 49 at its outer end which is adapted to be engaged by the tapered end of the valve stem 5() which is threadedly connected to the blocli 43. Extending at right angles to this reduced vpassageway 48 is a second passageway 51 which extends downwardly and is arranged in axial aline nient with the tubular passageway 34 formed in the body casting 6 ot' tie iron and best illustrated in Fig. 5.

ln F1 1. 6 and 7. the converter tubes 42 are illusti at ed as beingprovided with lillers which consist oi' the-spiral `wire elements 52 which are alternately arranged with the twisted strands 53. It will be seen that these lillers extend from the converter trap couplin'g 41 to the valve block 43 in each converter tube 42;

The handle portion 7 includes a wooden hand grip 54 which has its opposite ends connected to the upstanding arms 55 of a heat deiiectingplate 56 by means'ol the bolt 57 which extends axially through the wooden hand grip 54. This heat defiecting plate 56 is connected at its rear end to a lower heat deflectiiig plate 58 by the bolt 59 aud spacci' 60. The front ends o'l these heat detlectiugr plates 56 and 58are connected by the cap screw 47 and spacer element 6l, the screw 47 having` been previously referred to as lacing threadedly received within the bore 24 ol" the boss 25 carried by the body casting 6. It Will be seen that this bottom heat detlecting plate 58 has its front end maintained-in spaced relation to the connecting plate 44 for the valve blocks 43 by the locll: nut 62. The screw 47 forms a connection between the body casting 6 and the handle portion 7 of the sad-iron which will permit the lateral swinging of the handle portion. as illustrated in Fig, 2 by the arrow line. For the purpose of locking the rear end of the handle structure 7 to the remaining por tions of 'the sad-iron, a flexible latch meniber 63 is provided which is toi-med with the diverging legs 64 having their lower ends turned at right angle'shior being connected to the tubular bosses 36 by the screws 52 which 'fasten the 'ends ol the burner tubes 28 Vand vtheir caps 3l to "the said tubular bosses 30. In Fig. 4 this latch member (323 is illustrated'as having the notches 65 formed therein and arranged for alining with a cutout portion 66 formed in the rear end of thc k Y A The upper free en'd 63 of this latch member is conveniently arranged in respect to the hand grip 54 for permitting the user to flex the latch member toward the fuel tank 37 for disengaging the notches 65 of the latch member 63 for permitting the entire handle structure 7 to be swung laterally for exposing the interior of the body portion of the sad-iron.

The operation of this sadiron for converting industrial or denatured alcohol into gas suitable to be burnt for heating the iron is as follows It will be seen that the tank 37 may be lled to a desired level with industrial or denatured alcohol b removing the cap 38. After this tank 37 ias been provided with alcohol, the latter will feed by gravity i through the tube 40 into t-heconverter trap coupling 4l. This couplingwill lill up with liquid alcohol until it reaches the level of the converter tubes 42 whereupon it will flow through these tubes, it being noted by inspecting Fig. l that the converter tubes 42 are inclined downwardly? toward the front and of the sad-iron. The alcohol in passing through these converter' tubes is caused to travel a tortuous path by the filler elements` 52 and 53 located in these converter tubes.

These filler elements are intended to produce a whirling or spiral motion by the spiral wires 52 and twisted strands 53. The flow of the alcohol into the burner tubes 28 and cored enlargements 26 is controlled by i'` stems 50 should be operated for permitting :a t be heated.

a small quantity of the alcohol in its liquid state to be fed into the flame pockets formed in the bottom casting 5. The valves should then be shut oil' for preventing further feeding of the liquid fuel into the bottom casting' and the liquid fuel that has been discharged should then be lighted. 'The burning'of this liquid fuel causes the converter tubes 42 andl the burner'tubes 29 The heating of the converter tubes 42 and the liquid fuel therein, will cause this fuel to vaporize or in other words the liquid fuel will first start to boil and will then be changed into .highly expanded" gas or vapor. As this gas is produ-ced, the valve stems may be operated for withdrawing their tapered'ends from the valve seats 49 for permitting this gas to pass through the passageways 48, in the valve blocks 43, and into the passageways 51. This gas passes downwardly through these passageways 511. and enters the tubular passageways 34 formed in the body casting 6. The travel of the gases through these passageways 34 causes the drawing in of air through the air inlets 36. This mixed gas and air will produce a llame that is intensely hot and free from smoke or odor.

It will be understood that the filler elements 52 and 53 in the converter tubes 42 will retard the travel of the liquid fuel from the tank 37V to the burners and this ref tarding of the travel of the fuelwill permit the same to be converted into gas by the time it arrives at the valve blocks 43. The filler elements 52 and 53 and the converter trap coupling 4l will prevent the return of any of the gas into the tank 37, for the reason that the gas is lighter than the liquid and will not travel upwardly through the liquid in the arms of the coupling 41 and in this way will maintain an even pressure at the valve outletsrso long as the flame is. kept burning inside the iron body.

It is now believed that the constructionV andy operation of this sad-ironwill be under-k stood from the above detail description and that no further explanation is believed necessary. l i.

It is to be understood that the form of this invention herewith shown and describedfis to be taken as a *preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims. i
