To all whom it may concern:

Be it known that l, Jol-IN B. Gorro-EN, a citizen of the United States, and a resident of Terre Haute, in the county of Vigo and State of Indiana, have invented a new and Improved Sad-Iron Heater, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a double faced sad iron and a heater supporting handle therefor constructed and arranged to permit the reversal of the said iron; to provide a heater for an iron of the character described which heats the upwardly disposed surface of the iron while the lower surface is being utilized in the operation of ironing; to provide a handle for the sad iron which is air cooled at the points of contact to limit the heat transference from the iron to the said handle; t0 provide an air cooled supporting member for the heater within said handle; and to provide a generator of a safe, economical and effective construction.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings, in which like characters of reference denote corresponding parts in all the views, and in which- Figure 1 is a perspective view of a sad iron and heater connected therewith, constructed and arranged in accordance with the present invention; Fig. 2 is a longitudinal view, on an enlarged scale, of a sad iron constructed in accordance with the present invention; Fig. 3 is a vertical cross section taken on the line 3-3 in Fig. 2; Fig. 4 is an end elevation of a sad iron and heater, constructed in accordance with the present invention, the lower end of the handlevbeing removed to show the connecting boss for the handle of the iron; and Fig. 5 is a cross section taken on the line 5-5 in Fig. 2.

The class of irons to which the present invention relates is that wherein the iron is self-heated, and more particularly wherein the fluid employed is alcohol or gasolene, these liquids being adapted to be gasied by heat. The alcohol is contained in a small supply tank 6, the receiving opening of which is closed by a screw plug 7. The screw plug 7 is constructed to form a closure for the upper end of the neck 8, and is provided with a centrally disposed pipe 9. The

pipe 9 is provided at both ends with small air passages 10, 10.

The tank 6 is suitably connected with a T- pipe 11. In one extension of the T-pipe 11 is provided a passage 12, the lower end whereof is contracted to deliver within a screw threaded boring of the head of the T- connection. Within the screw threaded boring is mounted a screw 13, on the end of which is formed a cone 14 to operate as a valve to close the entrance to a small passage 15. The screw 13 is provided with a knurled head 16, and any leaking around the screw is prevented by a gland 17, in the packing space 18 whereof is provided any suitable packing material. rIhe gland 17 is screw threaded upon the end of that branch of the T-pipe 11 in which the said screw 13 is mounted.

The l'pipe 11 is driven fXedly into the bore of a fluted tube 19. The tube 19 is elongated, and inserted in a bearing boss 20. The boss 20, on the inner end, furnishes a circular bearing for the rotation of the double faced sad iron 21.

The sad iron 21 is hollowed to form an interior chamber 22, into which are extended, from the outside, air passages 23, 23. The passages 23, 23 are disposed adjacent to the smoothing faces of the iron 21. It is within the chamber 22 that the heating torch is suspended. The iron 21 is pivoted, at the end opposite that resting on the boss 20, upon a screw 24. The screw 24 is extended through a perforation in the end 25 of a handle 26. The screw 24 is held in screw threaded engagement with a tapped hole centrally driven in a boss 27.

In the operation of ironing, when performed by a device as herein shown and described, the iron 21 is rotated on its pivotal bearings to present upwardly and alternately the smoothing faces of the said iron. The iron and handle are locked in operative position by means of a spring actuated latch 28, the head 29 whereof is adapted to engage recesses 30, 30 disposed on opposite sides of the center of the boss 27. The said latch 28 is pivotally mounted at 31 on the end of the handle 26.

It is to prevent the radiation from the handle 26 that have provided the fluted construction for the plug 19, and have fluted the face 32 of the boss 27 By means of this construction the plug 19 and the boss 27 present, instead of a continuous surface, a

series of edges to the metal of the handle 26 with which they are in contact. The handle 26 is provided with a non-conducting hand hold 33, which may be constructed of wood or any suitable material. As a fender or shield for the hand of the operator from the heat radiated from the iron 21 there is provided a shield 34. The shield 34 is fixedly secured between the uprights of the handle 26, and interposed between the said hand hold 33 and iron 21.

The torch by which the iron is heated is constructed from two tubes 35 and 36. The tube 36 is superposed and supported on the tube 35 by the connections 37, 37 and a saddle 38. The saddle 33 is cast with the tube 35, and forms a seat for the end of the tube 36. The tube 36 is provided with a series of jet openings 39, 39, laterally disposed in thev The gas burned in the torch is generatedfrom the fluid stored in the tank 6, which is fed therefrom through the passages 12 and 15 tothe rear end of the tube 35, which is provided with a filling of asbestos liber 40. At the forward end of the asbestos illing there is provided a line copper wire gauze lining 41. inwardly disposed in the tube 36, and adjacent to the chamber formed by the wire gauze 41, is a plug 42, wherein is formed a pin hole passage for the delivery of gas from the chamber formed by the lining 41. Adjacent to the delivery end of the said pin hole passage is an air supply opening 43, which communicates with the chamber 22 of the iron 21, and the function of which is to supply atmospheric air to the vapor as delivered from the pin hole passage, and to thereby form a mixture which burns a blue flame at the openings 39, 39. The alcohol, gasolene or oil, as the case may be, which is delivered through the passage 15, pereolates through the fiber 4() into the chamber formed by the lining 41. When the torch is in operation, the heat generated by the flame at the openings 39, 39 is transmitted to the tube 36, and from the said tube transferred by the saddle 38 to the chamber surrounding the lining 41. The heat thus produced in vthe chamber is communicated to the lining 41, and by the said lining to the liquid delivered thereto through the fiber 40. IThe effect of the heat in the chamber formed by the said lining is to gasify the liquid in the said chamber. The gas thus produced is delivered through the pin hole passage Yin the plug 42. The current of gas passing out of the said pin hole passage draws, through the opening 43, air into the forward end of the tube 35. The air and gasilied liquid are carbureted in the forward end of the tube 35, and delivered therefrom through the connections 37, 37 to the interior of the tube 36. The gas thus delivered to the tube 36 is of highly explosive character, and burns a blue flame at the openings 39, 39.

The operation of the sad iron when thus constructed is as follows: At the initiation of the operation the screw 13 is retracted to lift the cone 14 of the pin valve to open the passage 15. The liquid contained in the tank 6 thereupon flows into the said passage,

and through the fiber 40 into the chamber formed by the lining 41, and through the pin hole passage in the plug 42 into the forward end of the tube 35. rEhe liquid thus delivered is carried through a passage 44 formed in the under side of the tube 35, into a priming pan 45 integrally formed on the tube 35. lWhen suflicient oil has passed into the pan 45, the same is ignited by eX- tending a taper, or other suitable device, l

through one of the passages 23, 23 to ignite the liquid contained in the pan 45. The heat thus genera-ted in the pan 45 gasies the liquid contained in the chamber formed by the lining 41, and the samel is delivered therefrom through the opening in the plug 42. rlhe gasified oil is carbureted in the tube 35 and delivered as above described to the tube 36. l/Vhen thus delivered, the gas seeks exit through the openings 39, 39, and is there ignited by the flame from the pan 45. When it is observed that gas is formed and properly burning at the openings 39, 39, the screw 13 is retracted to open the supply passage 15 and permit the continuous flow thereafter of the liquid stored in the said tank 6. As long as the liquid is supplied from the tank 6 the heat produced by the burning of the gas at the openings 39, 39 will be sufficient to gasify the liquid when and as received in the chamber formed by the lining 41.
