L. RUBINSTEIN ELECTRIC IRON Filed Aug. 25, 1941- [lllz Patented Nov. 17, 1942 UNITED lSTATES 2,302,476 i ELEcTB-rc moN Louis Rubinstein, New York, N. y. Application August 25, 1941,'seria1 No. 408,249 (o1. sii- 77) i 1 Claim.

This invention relates to an electric iron, the object of the invention being to provide the iron with 4automatic means for keeping the water level in the tank of the iron constant and without necessitating the frequent refilling of the tank by the operator.

' Another object of the invention is to provide means whereby the steam from the iron can be caused to pass through perforations in the bottom thereof to contact articles being pressed or to have the steam pass through a hose or conduit to a remote point or to escape into the atmosphere.

This invention also consists in certain other features of construction and in the combination and arrangement of the'several parts to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail,-reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts vthroughout the several views, and in which- Figure 1 is an elevational view showing the parts of the invention associated with an iron.

Fig. 2 is a vertical sectional view through the iron.

Fig. 3 is a view in section through the water receptacle. n

Fig. 4 is a sectional view through the steam tube with the valve therein in elevation.

In these views the iron is shown at A and it is provided with a tank I, which is heated by an electric coil. 2 in theusual or any desired manner, the connections from the coil to an electric supply being shown generally at 3. A pipe 4 eX- tends into the tank I through a nipple 5 in the upper part of the iron in one end thereof and this pipe is adjustably secured in the iron by the nuts 6 so that theA distance the lower end of the pipe is from the bottom of the tank can be adjusted to regulate the level of the water in the tank. A hose 1 is connected to the outer end of the pipe in any suitable manner and said hose is connected toa water container 8 by a cock 9 and said water container is provided with a flllwill enter the container l through the hose I and thus the water willagain begin to flow into the tank until the water level closes the lower end of the pipe. Thus the water level in the tank I is automatically maintained and there is no necessity for the user 'tostop work and rell the tank', `as inl irons vas now constructed.

A vertically arranged tube I3 passesl through.

the iron and has its lower vend connected to a downwardly flaring" member Il fastened to the bottom of the iron and covering the perforations I5 formed in the bottom of the iron. The upper end fof the tube passes through the top of the iron and this end is closed by a cap I8 and a branch tube I'I extends upwardly and outwardly from the upper portionof the tube I3. A valve I8, made in the form of a piston is slidably arranged in the upper portion of the tube I3 and has a stem I9 connected therewith which through the cap and has a handle 20 at its upper end. A pin 2l extends from the upper portion of the stem and is adapted to engage the bayonet slot 22 formed inthe cap for holding the valve I 8 in lowered position. When in lowered position the valve I8 will pass below a port 23 in the tube I3 and below the plane of the part I1, y

whereby steam will pass through the port 23 and passfthrough thev part II. A spring 25 normally holds the valve' in position closing the part I1 and opening the port 23. In this position of the partssteam will pass through the port 2 3 ing nipple I0 in its top closed by a cap II in a fluid tight manner.

Of course the water container must be held in an elevated position so the water therefrom will pass through the hose 1, when the cock 9 is open, through the pipe 4 to the tank I. When the water level in the tank closes the lower end of the pipe the flow of water will be stopped as o1' course no air can enter the container. However,"

as soon as the water level in the tank drops air 66 and. ow 'downwardly through the pipe I3 and pass throughtheperforations I5 in the bottom of the iron and contact articles being ironed.

When it is not desired to use the steam, the

valve Is lowered and held in lowered position by the pin 2| engaging4 the bayonet slot 22 and the steam will pass-through the port 23 and escape through the part I1. f If desired a hose can. be connected to thisjpart I1 for leading Vthe steam to a distant point or for use in steaming an article or object. Y

Thus it will be seen that I have provided means for automatically maintaining the water in the tank I of the iron at a constant level which removes the-necessity of the user frequently relling the tank, with means for supplying the steam to the article being ironed and cutting oif the fsteam supply to the article whenever desired.

Itis thought from the foregoing ldescription invention will be readily apparent.

that the advantages and novel'features of theV It is to be understood that changes may be made in the construction and'- in the combination and arrangement of the several partsprvided jacent the top of the same and being provided with a forwardly and upwardly inclined vent branch above said port extending out of said top,

a downwardly aring member on the bottom of the tube fitting against said bottom and spanning said group of apertures, a plunger-type spring tensioned valve in the upper end of the tube normally closing said branch and opening said port .and slidable into a downward limit of movement to open the branch and close the port, said valve having an upstanding stem extending out of the top o! the tube for moving the valve under nger pressure exerted on the stem, and

cooperating devices on said stem and in said tube, respectively, for locking the stem and valve down in said limit of movement thereof.
