Specification of Letters Patent.

Application led October 19, 1917. Serial No. 197,419.

To all whom t may concern.'

Be it 'known that I, PrrrLIrBUs TUFENK- GIAN, a subject of the Sultan of Turkey, residing at Boston, in the county of Suffolk and lState of Massachusetts, have invented new and useful improvements in Sad-irons, of which the following is a specication.

The present invention relates to sad I ironsparticularly those which are self heated-and it is the object of the invention to provide such a device which will provide a steady heat of effective temperature without danger of overheating and scorchingwhich is a serious objection to the old style sad iron as Well as the modern ones heated by gas, electricity, gasolene, etc.

A further object of the invention is the provision in a sad iron of a chamber for water or other' liquid which serves as a medium to transmit the heat-preferably supplied by an inclosed gas burner-to the ironing surface, so that the temperature of said surface can not rise above the boiling point of water, thereby giving the desired safeguard against overheating. Y

The invention also aims to provide a sad iron of the nature indicated which is comparatively simple in construction, easily manufactured, and eflicient in use.

With the foregoing and other objects in view, which will appear as the nature of the invention is better understood, the invention resides in the construction and combination of parts hereinafter set forth, it being understood that changes can be made within the scope of the appended claims, without departing from the spirit of the invention.

The invention is shown in the accompany* ino` drawings, whereinigure 1 is a perspective view of the improved sad iron.

Fig. 2 is a longitudinal vertical section thereof, portions being shown in elevation.

Fig. 3 is a sectional detail on the line 3-3 of Fig. 2.

The device comprises a chambered body A and forming a receptacle for water or other liquid used as the heat transmitting medium, and having a cover or top 5 removably fastened on by screws 6 or other means. A suitable handle 7 is secured on the top 5 for manipulating the iron, and the bottom or ironing surface is indicated at 8. V The source of heat or heater as shown, is a gas burner, and the front and rear ends of the body 4l have inwardly projecting bosses 9 and 10, respectively, provided with the receptive cavity 11 and opening 12, the last named extending through the heel end of the body. A tubular member 13 extends longitudinally within the chamber of the body el and its ends are fitted in the bosses 9 and 10, said bosses "being preferably provided with packings 14 embracing the tubular member 13 to prevent leakage of the water past the ends thereof. lThe nose of the body has ports or outlets 15 leading from the cavity 11 to the atmosphere for the eX haust of the products of combustion from the member 13.

The hydrocarbon burner embodies a burner tube 16 projecting axially within the member 13 from the rear and its forward end is centered and supported in the member 13 by a spider 17 secured on the forward end of the tube and fitting slidably in said member. A plate or dish 18 is secured on the tube 16 and has an apertured portion 19 extending across the opening 12 and rear end of the member 13, said portion of the plate being preferably dished to extend into said opening and end of the member. The marginal portion or flange of the plate 18 is removably fastened to the rear end of the body by screws 20 or the like, thus holding both the tube and member 13 in place, it being noted that the rear end of said member abuts against the plate. By loosening the plate 18, the tube 16 can be withdrawn, thereby also removing the plate 18 and spider 17 with it, and this permits of the withdrawal of the member 13 through the opening 12. This assemblage enables the parts to be quickly put together and taken apart for repairs, cleaning and replacement.

The rear end of the tube 16 protrudes from the plate 18 and provides a nipple for the connection of a hose to conduct gas to the sad iron while using it, as will be understood. That portion of the burner tube 16 within the member 13 has gas outlet apertures 21 from which jets of gas issue to support the flame which is directed radially against the walls of the member 13. Air enters the member through the apertures 19 to mix with the gas and provide the llame. The apertures 21 are preferably arranged to direct the jets toward the outlets 15, thereby creating a draft through the .member 13 from the rear to the front, so as to suck in air at the rear, and expel the products of combustion through the forward outlets. The member 13 not only keeps the Water and flame separated but also acts as a mixing chamber for the air and gas, and this member being heated by the flame Will heat the eircumj acent Water. The Water being heated Will transmit the heat to the ironing surface, thereby giving an ironing temperature up to the boiling point of the Water, and since Water will not rise to a higher temperature it Will not therefore overheat the ironing surface. The top 5 has an upstanding spout 22 for the outlet of steam and for refilling the Water chamber from time to time. The spout is preferably of glass and graduated so that a pointer Q3 upstanding therein from a float 24a in the Water chamber Will indicate the amount of Water therein.

That is claimed is :n

1. A sad iron having a liquid-containing chambered body, a tubular member extending through the chamber-thereof and having its ends supported by and communicating through opposite portions of said body, and a burner tube projecting into said' member from one end thereof and having apertures arranged to direct flames against the Walls thereof at an angle toward the other end.

2. A sad iron embodying a liquid-containing ehambered body having bosses at its opposite ends, one having an opening for the inlet of air and the other having a cavity and an outlet leading therefrom, a tubular member in said body having its ends fitted in said opening and cavity, 'packings in the bosses embracing said member, a heater projecting into said member from said opening toward the cavity, and means for supporting the heater from the body and holding said member in the bosses.
