My invention relates to a new and .im-

.proved form of steam pressing 1ro n. One. of the objects of my invent on is to provide a new and improved pressmg ron 5 of the type in which steam is generated within the iron itself and is caused to con tact with the fabric to be pressed, for the intermediate casting or member 14 are connected to the bottom casting or member 15 purpose of moistening it.

Another object of my invention is to provide an iron of this type having a simple,

chea and eflicient construction.

Ot er objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof.

. invention.

As shown, for example, in Fig. 5, the iron is composed of a top casting 7, an 1nterse mediate casting 14 and a bottom casting 15.

The bottom casting 15 is provided with passages 30, and 30 which are formed during the casting operation by any sultable means. The assage 30 is provided with a as series of per orati'ons 28.. These passages 30, 30 and 30 may be considered as. form ing an angular or L-shaped part consistmg of the passagesBO and 30", which 1s connected to the passage 30 intermediate the ends of the said passage 30 These perforations 28 are preferably internally threaded and. they can be closed by nipples 29 as .'shown in- Fig.5. The tops of the mpples extend above the adjacent bottom of the revent an escape of liqu1d such as water w ich may e present in the said passage, through the hollow mpples 29. However, if any water 1n the passages 80, 30' and 30 is vaporized by means of sultable heat then the steam can readlly escape through the hollow mpples 29.

' The inlet end of the passage 30 has a coupling nipple 17 connected thereto and the ends of the passageswhich are left open mg reexternally threaded ends of the bolts 19 in the body of the iron, in the casting operl6 ation, are closed by threaded closure members 31, 32.and 33.

The intermediate casting 14 of the iron rests upon the bottom casting and the top castin '7 rests upon the intermediate casting 14. 1e top casting or member 7 and the by bolts 18, 19 and 20. The bottoms of said bolts 18, 19 and 20 are externally threaded and fit into internally threaded, recesses in the bottom casting 15. The shank of the bolt 18 passes through a boss 8 of the intermediate casting 14 and the upper and externally threaded end of said bolt 18 passes through the top castin 7 and through the front end of the hand e H so that a nut 9' suitably holds these parts together at the front of the iron. p

The bolts 19 and 20 are similarly secured to, the casting 15 and they ass through bosses 10 at the rear of the casting 14, which correspond to the boss 8. The upper and and '20 are engaged by nuts 11 which perform the same function as the nut 9 hereto fore described.

The intermediate casting 14 is provided witha door D hinged at the bottom thereof and this door D is ke t in place by a latch '85 23 turnably mounte upon a horizontal screw 22 which is connected to a vertical projection 24 of the intermediate casting. 14'.

The .bottom casting 15 has a flame d'e; flector or shield 31 secured thereto by means of the'screw '32. The intermediate casting 14 also has a gas burner 1 secured thereto by a screw 16 and the gas burner'l is connected to a gas pipe G. The gas burner 1 l is adapted to produce a horizontal flame which projects between the shield 31 and the top of the bottom casting 15 so that the heat produced by the flame is downwardly deflected and instantly heats the bottom casting 15. g

The coupling nipple 17 is connected to a water pipe W having a control valve V.

The flow of the water is normally controlled by the valve V'so that it drops slow- 1 into the passage 30 and is converted into steam by the heat of the gas flame, If, However, a few excessdrops of water enter the passage 30, they cannot touch the cloth of a valve which was controlled by the'operator. If the operator carelessly permitted the steam control valve to remain open too long, then the fabric which was being pressed was treated with an excess of steam which was highly disadvantageous.

According to my invention, I provide the passage 30 with a normally open exhaust passage so that the greater portion of the steam normally passes out of the iron through this exhaust passage or pipe E, and I provide a control valve for the exhaust pipe E whereby it is impossible for the fabric to receive an excess of steam. 1

As shown in Fig. 5, for example, the passage 30 is provided with an upwardly ex tending pipe 33 tightly connected thereto. The said pipe 33' is provided with a hollow flange 12 which rests upon the casting 14. The horizontal exhaust pipe E is connected with flange 12 and said flange 12 has a vertical passage provided with a vertically slidable valve rod 5 which is shown in Fig. 6 in its upper or open position. The top of the flange 12 is externally threaded and it is connected to the top casting 7 by the nut 4. The top of the valve rod 5 is provided with a cap 2 secured to said rod5 by a screw 3 and a compression spring 6 is provided intermediate cap 2 and nut 4: for forcing the valve rod 5 to the upper position.

A standard 34 is secured to the casting 7 and a lever 35 is turnably connected thereto at 50. Said lever is also connected to the forked top of the cap 2 by means of the pin -51 so that by pressing downwardly upon the head 36 of the lever 35 the valve rod 5 can be moved to its lower position in which it prevents the steam from passing out through the exhaust pipe E.

Hence, the fabric receives at all times a regulated and preferably small amount of steam which is determined by the extent to which the valve V is opened and the rela tionship between the openings of the hollow nipples 29 and the ease with which the steam can escape through the exhaust pipe E. If it is necessary'to supply more steam to the fabric, then this is accomplished by closing the exhaust pipe E. i

This apparatus also makes it possible to obviate any fine degree of adjustment of the water valve V. It is obvious that more water can be allowed to enter the iron than is required for the steam consumption of the same because a large amount of the steam can be caused to escape through the exhaust pipe E and'as much of this steam as is desired may be caused to act upon the fabric by merely closing the valvecontrolling the pipe E.

In irons of the type heretofore made in which all the steam generated was caused to act upon the fabric, avery delicate'adjustment of the water control valve was necessary and this was impossible to secure in actual practice and if an excess of water was allowed to enter the iron this, in time, caused the water to directly touch the fabric, which was highly objectionable. However, according to my apparatus where an excess quantity of water may be permitted to enter the iron and where the flame is made sufficiently powerful to vaporize more water than is required for the normal use of the iron, such fine adjustments are not necessary.

It will be noted that the gas heater is located wholly above the bottom casting 15 and that water directly enters the passage 30. Hence, the water which directly enters the casting 15 is directly heated by conduction, the heat for this purpose bein supplied by the superposed burner 15. t will also be noted that in distinction from prior devices suchas illustrated in Hoffman U. S. Patent No. 1,516,923, that the water space of my improved iron is located wholly below the heater, that is, the water is not heated in tubes or the like located above the heater. Since, in my improved iron, the flame is downwardly directed, the top of the body of the iron remains cool.

In the embodiment shown in Fi 7 the constructional features are substantmlly the same as before described but the means for operating the valve rod 5 are arranged 1on gitudinally instead of transversely as in the embodiments shown in Figs. 1-6. While, I have shownawater inlet assage so disposed that the waterentering rom the coupling 17 first moves in a path substantially parallel to the central longitudinal line of the iron, and then moves in a path which is erpendicular to said central longitudinal me,- it would not be departing from my invention it the water inlet assage 'throu h which the water passes be ore reachin t e member 30 would have no part thereo parellel to said member 30".

I claim i 1. A hollow steam iron having a bottom casting, a as heater located above said casting and a apted to heat the same, said casting having a water inlet passage laterally spaced from the longitudinal central line of said casting, said castin also having a steam passage communicatlng with said water inlet passage, said steam passa e havin' openings communicating with the ottom 0 said casting in the central portion of the bottom of the casting.
