SAD-IRON.

. Specification of Letters Patent.

aaissuno Patented Feb. 8, 1910.

Application filed ilanuary 29, 1909. Serial No. 474,935.

To all whom it may-concern:

Be it known that we, O'r'ro SPArIaand CHARLES STICHLER, the former a citlzen of the United States, the latter a subject of Germany, having resided one year last past in the United States and declaredhis intention of becoming a citizen thereof, both residing in the city and county of Phila delphia, State of Pennsylvania, have invented .a new and useful Sad-Iron, of which the following is a specification.

()ur invention consists of a sad iron having means for supplying air andgas to tlfie t e base of the iron, while also producing a maximum of heat with a minimum of gas burner on an enlarged scale.

and avoiding the smell of unconsumed gas,

' and other details are presented, aswill be hereinafter described.

For the purpose of explaining our invention, the accompanying drawing illustrates a satisfactory reduction of the same to ractice, but the important 'instrumenta ities thereof may be varied, and so it is to be understood that the invention is not limited to the'specific arrangement and organization shown and described.

, Figure 1 represents a perspective view of a sad iron embodying our invention. Fig. Qrepresents a longitudinal vertical section thereof. Fig. 3 represents a transverse vertical section thereof. Fig. 4 represents a top or plan view of the bodyfof t e iron. Fig. 5 represents a transve se section of the Fig. 6 represents a bottom plan. view of a portion of the top plate of the bod Similar letters 0 reference indicate corresponding parts in the figures.

Refer'rin to the drawings A designates the bodyo a sad iron, the same being hollow forming the heating chamber B. C

designates the top plate of said body, the

same being connected .With the sides of the latter by the ivots D, whereby said top may be raisedin the direction as indicated by the arrow, Fig. 2.

E designates a plate comprising a portion of the rear wall of the bodyA, the same dcpendincg from the pivotal end of the top plate i Within the chamber B is the pipe F com prising a gas burner, the same having in its underportion the ports or gas jets G, which extend in'radlal direction so as to direct the burning gas or flame to right and leftover the base H of the body of the iron, as indicated by the arrows, Figs. 3 and 5. The

burner F depends from the pipe J which is connected with the top plate 0 and continuous of the bent pipe K which constitutes a portion of the handle of the iron, the upper limb L of said pipe K having the wooden or other rip 'M thereon'and secured thereto. In said limb and grip are air intake-openings N, N, and on the end of said limb is the gas supply-nipple P, whereby combined air and gas areadmittedinto said limb after i i the manner of a Bunsen-burner and from thence directed to the jets G Where they are consumed.

*In'the base H of the body is a longitudi- I really-extending channel Q, the same forming an air receiving chamber which communicates with the chamber B and is disposed below the burner F. In said base, there are also transversely extending passages R, whose outer ends are open to the atmosphere, and whose inner ends open into the channel or chamber-Q. V y

The gas at the jets G may be ignited by raising the plate 0, whereby the burner F is accessible for said purpose, said plate then being loWered and secured by the latch S which is pivoted to said plate and having a:

head I which is adapted to be seated in the recess U in the nose of forward end of the body A. As the gas-burns, air is drawn through the passages B into the chamber. Qand the latter is supplied with large volumes of the same. The air is'impacted against the flames, whereby the latter are deflected laterally and injected againstthe upper side of the base H, so as to highly heat the same for effective operation of the iron, it'being noticed also that there will be complete combustion of gas and a consequent.

maxlmum of heat with a minimum consumption of the gas, while the smell of unconsumed gas-is avoided.

Attention is directed to the fact that there is a natural draft. through the body of the iron to the openings V provided for the escape of the products of combustion, the air being admitted to the burner below the same and then sup lied-to the gas to cause comparative pert eict combustion-of the latter without ermitting the flames to'ap car on the exterlor of the iron. As gas an air in the natural condition are admitted into the handle, the latter is kept incool condition- ,we claim as new and desire to secure by Letters Patent, is:- I

1; In a sad iron, a hollow bod a movable top therefor, a burner carried y said top, means for supplying gas to said burner, said burner having gas ets on the under side thereof, and an air-receiving chamber in said bod said chamber being central in the base an the latterhaving its walls on the sides of said chamber to which said jets are deflected.

2. In asad iron, a body having intake assages directly in the base thereof, said Ease having so rated side walls, formin a chamber centra ly between the separated s1de walls of said base, said passa es leading to said chamber, and a suspended burner having jet openings deflected to the right and le to said walls, said chamber being between said jet openin whereby air is supslied to the inner si es of'the flames prouced at said jets.

3. In a sad iron, a body, the base thereof having an air reeeiving chamber centrall therein with walls on opposite sides thereo and an air-intake passage in said base leading from the side of the body through said base into said chamber, a burner in saidbody oversaid chamber the same havin jet 0 enings which are deflected to said si e wal of the base, and a movable top carrying said burner and its supply tube.

4. In a sad iron, a hollow body, a burner therein near the bottom of said body, and a rigid gas-conveying tube onsaid 0 dy in Gas Iron Company.
