SADIRON CONSTRUCTION Original Filed April 9, 1923 Patented June 17, 1930 JAY C. STEESE AND CHESTER A. HOFIE, OF AKRON, OHIO, ASSIGNORS TO THE AKRON LAMP COMPANY, OF AKRON, OHIO, A CORPORATION OF OHIO SADIRON eons-"rationals Application filed April 9, 1923, Serial No. 630,761. Renewed November 25, 1929.

The present invention relates to a sad iron which is heated by a fluid fuel, such for instance, as gasoline, kerosene, or any other similar or analogous fluid fuel.

' The object of the invention is to provide an iron of the type described, which is not unduly heavy, and one in which the font containing the liquid fuel is not unduly large nor in the way of one manipulating the iron.

A further object of the invention is to so support the font that it is heat insulated from its support.

A further object is to provide a construction in which the pipe containing the regulating needle in association with the vaporizer, is arranged adjacent the burner so that after the burner has been in operation for a short period of time, the heat from the burner will vaporize fuel in the fuel pipe ahead of the portion containing the valve, and of course, ahead of the vaporizer, so that the valve is essentially regulating the passage of a gas rather than a liquid fuel,

and therefore regulation of the burner by the needle valve is more easily accomplished.

A further object of the invention is to provide a structure for a sad iron in which the burner may be started by preheating the fuel in a vaporizer which is so arranged that the heat from a match may be employed in the starting operation.

Further obects of the invention are to provide a structure which may be quickly and easily assembled within the body of the sad iron proper and which'permits ready removal of the vaporizer for replacement or repair.

Reference should be had to the accompanying drawings forming a part of this v specification, 111 which Fig. 1 is a perspectlve is usually the case, with a heavy lower bottom portion 2 containing a proper amount of metal which will absorb heat and retain the same, which construction is of course common in sad irons generally.

Above the base portion 2 there is an outside wall 3, which extends all the way around the base and upwardly for a suitable height. This wall at its upper edge receives a cover 4 whichis fastened to the walls 3 by means of screws or any other suitable fastening means. The cover 4 carries the handle by which the sad iron is operated, the handle in this instance consisting of a U-shaped band of metal such as indicated at 5, which is fastened to the cover 4 in any suitable manner, as indicated at 6. The free ends of the U-shapedmember 5 are secured to the ends of a grip member 7 which is preferably of material which is non-heatconducting, such for instance as wood.

The font 8 containing the fluid fuel which is to be supplied to the burner that will be later described is supported by means of a curved bracket 9 which at one end is secured directly to the portion of the U-shaped member, 5 which supports'the handle or grip 7. This bracket 9 is spaced from the.

member 5 by means of asbestos packing, such as indicated at 10', which is introduced between the bracket and the member 5 so that heat will not be conducted the one from the other. The means by which the bracket 9 is fastened may be any desired means, as bolts 11.

The above, structure prevents the transfer of heat from the U-shaped member 5 to the member 9, so that the fuel reservoir is well insulated from the heat, which might otherwise be conducted to it from the sad iron when the same is in operation. This bracket 9 at its lower end is provided with a U-shaped slot 12 which is adapted to receive a portion of a member secured to and extending downwardly from the font 8, which member at 'its outer surface is threaded and receives a knurled nut 13, this nut being so positioned that the bracket 9 at the slotted end thereof may slip above the nut 13 so that when the nut is tightened by turning the same it forms a means for effectually securing the font to the bracket 9 in such a manner as to prevent its being easily detached therefrom except upon pos tive operation of the knurled nut 13.

Attached to the fixture on which the nut 13 ismounte dis a pipe 14 of smaller diam eter and this pipe is by means of a suitable cup, connected with an arm 15 which in turn forms a Y-connecti'on'with a tube 16. This tube 16 receives a stem 17 which at its outer end has a knurled head 18. At its inner end the stem is pointed, as indicated at 19, and co-operates with a conical seat 20 formed at the end of the tube.

Attached at the end of the tube is a thinwalled pipe 21 of small diameter, which preferably'is formed approximately circular in shape. This pipe is the vaporizer, the function ofwhich is well understood by those-familiar with the art. 7

Mounted within the walls 3 and attached to the base is a burner which comprises a long portion 22 having-slots or other orifices such as indicated at 23, by which the flame from the burning gas is directed upon heavy metal base portlon 2. The burner is roundedat one end and terminates in a short In the rear wall of the body portion of the sad iron there is a' vertical slot27 and this slot at its lower end iswidened out as indicated at 28.

The pipe 16 with its branch pipe 15 and the vaporizer 21 are a unitary structure, and are capable of being inserted and removed from the interior of the sad iron structure as a unit. It will be understood that this is a desirable and necessary feature because if there is any carbonizing or clogging in the passageways, it will take place either in the tube 16 or in the vaporizing coil 21, and therefore it is desirable and necessary :that these may beremovable and replace able in the event that 'necessity'demands.

The tube 16 and its branch pipe 15 are inserted through the lower widened portion 28 of the slot, and at the same time the end 21? of the vaporizing coil is inserted through the opening 26 in the mixer 25. This serves to definitely position the tube 16 and the vaporizing coil, and not only is this structure'definitely fixed, but is definitely sup ported. The pipe 14, which is, as before explained, connected with the pipe 15, is definitely held in its position by virtue of the mounting of the font 8. when the font 8 is positioned and'held in its bracket 9, the connection with the pipe 14 serves'to maintain the tubejl6 and its allied parts in their definite mounted position. In fact, the font with the pipe 14:, the tube 15, the tube 16, and the vaporizer, are removable as a unit from the remainder of the sad iron structure, and from the construction which has heretofore been described it will be seen that the various parts of this unit which have been described may be disassembled. I I By reference-to Fig. 1 it will be seen that the tube 16 extends within the body portion of the sad iron for a short distance adjacent the burner 22, and additionally the 'vaporiz'- flng coil 21 also extends adjacent to the burner. v 7

After the burner has become ignitedv and is functioning the heat from the burner will heat the tube 22, and will cause the formation of gas in the tube 22 so that after the burner is going and functioning,instead of liquid fuel being delivered through the valve seat which is controlledby the valve rod 17 gas will be passing through and the vaporizing coil 21 or generator will be practic'ally'acting merely to further heat the gas delivered to it. I r

This has a distinct advantage in that it is a much easier matter to regulate the passage of a gas through the valve, and to obtain a nice regulation, than it is to regulate a fluid fuel. Of course, in the first instance and before the burner has sufficiently heated the tube 16, the fluid fuel will pass bythe valve in the tube 16, and will be regulated by the valve stem 17, but the continued operation of the burner causes the formation of gas within the tube 16 in the manner which has been described. 7 r

In the starting operation of the'sad iron, the valve 18 is 'open to a sufficient extent to permit fluid fuel to pass into the vaporizing coil 21. Due to the fact'that this coil is of small diameter and of thin walled material, which will easily absorb heat, it is possible to apply the heat of a match to the coil 21 and effectively vaporize ,the fluid fuel which is fed to it so that the gasified fuel passing from the coil 21 to the mixer 25, is delivered into the burner 22 and will be there ignited.

Of course, the application of heat by means of a match to the coil 21 is only required for a short time in order to supply the necessary heat for vaporizing the fuel in a preliminary way, for as soon as the gaseous fuel in the burner 22 is ignited and the heat. supplied to the vaporizer 21, will continue the vaporizing of all fuel that comes to it.-

As before stated, after the burner has Therefore,

been functioning for a short period of time, the vaporizing effect takes place in the tube 16, rather than in the coil 21. This has decided advantage for regulating reasons which have before been stated, and it has been found after long trials that carbonizing effects are very slow in making their appearance.

In order to permit a match or other lighted paper to be introduced to the coil 21, the side wall 3 of the sad iron is provided with an opening which is indicated at 28 in Fig. 4:.
