Application filed August 11, 1925. Serial No. 49,548.

' My invention relates to electrically heated irons and consists of improved means for supporting an iron and effecting the application and cutting off of the electric current when the iron is moved into various positions.

I One object is to construct my invention in such mannerthat it can be readily used and will prevent disastrous results which have heretofore-been caused by the heat of an iron when unattended by an operator.

Another ob'ect is to so make m invention that itwill' al ow the heating an j cooling of the iron while the latter is in a position out of contact with the ironing board and tilted. in a position allowing the operator to conveniently ascertain the temperature thereof. A further, object is to so construct my'invention in-connection with an. iron that it 'will' s'sess theabove advantages without requirmg the operator to rotate or cause the pushing of any switches.

. These objects and other advantageous ends which will be set forth hereinafter, I attain in the following manner, reference being had 25, 'to the accompanyingdrawing in which I Figure 1 is a side elevation illustrating my' invention appliedto an electrically heated iron, showing the latter in a tilted and sup ported position which effects the heating thereof, l I I v Figure '2. is a side elevation showing the parts in the ositions which they occupy while the iron is being used, ,FigureB is a side elevation showing said iron in a rearwardly tilted position effecting y the breakin of the-electric current and the cooling oft e iron,: Y

.Figure' 4 is a rear elevation of said iron and parts, and

4o igure 5 is'a fragmentary elevation of my a invention withcertain of the parts slightly, I

' changed in'shape from those lllustrated in Figures 1 to 4, and allowing the iron to be tilted rearwardto a greater extent than illus- I trated in Figure 3. 1 I Referring to the drawing 6 represents an iron which may be of any of the well known forms including va heating agent (not illus trated) to which electric "current is supplied through the medium of two connecting posts 7 and 8 which project outwardlyf through the 'top of the body portion 9 of the iron 'to the rear ofthehandle 10., I have illustrated an electric switch 11 which is claimed per se in my pending application for United States Patent, Serial. No.1

(532,821, allowed July 20th, 1925, and I have illustrated said switch in detachable connectionwith the posts 7 and 8 at a position to the rear of the handle 10, said switch, as illustrated in the present application, including a casing 1 having therein post connectors or contacts 3 and 14 for the respective posts 7 and 8. The contact 13 is directly connected .with a feed wire or conductor 15, while the contact 14 is in connection withan abutment member 16 which is spaced below the bottom of a tubular terminal or guiding member 17 Y The terminal17 is electrically connected to an electric conduit feed wire 18, said conductors 15 and 18 acting as the feed wires for electric current from any suitable source and enterthe casing 12 as clearly'illustrated. A metallic gravitating member 19, in the form of a ball, is adapted-to roll within the tubular terminal 17 and when the latter is'in an upright or inclined position as clearly shown in Figures 1, 2 and 4, the-ball will move by gravity into engagementwith the abutment 16, a portion of said gravitating member 19 still remaining within the tubular terminal 17 and in contact therewith, to complete an electric circuit through the iron to effect the heating thereof. I

The parts above specifically described are not claimed per se in the present application, but-are illustrated and described as showing a convenient and suitable form of electric switching means which'will be effective when used in connection with means new to be described for effecting the supporting of 'the .part of the iron is out of contact. with the ironing board.

A supporting iron in various positions and for effecting device or stand 20 has a tion or member 21, the upper part of which is secured to the :rear'face'22 of the body 9 of theiron by. a screw 23. The member21 is preferably made comparatively wide as shown in Figure 4 with its lower part 24 rolled or turned toprovide a bearing fora pivot or hinge pin 25. The part 24 is pos1 'tioned in spaced relation to and rearward of the'back of the iron and above the level of the ironing surface26 of the base 27 of the i'rorrwhen the iron is in operating position as clearly shown in Figure 2. Furthermore, the part ,24of the member 21 is discontinued within its length to provide a recess or notch 28' as clearly shown in Figure 4, sa1d notch serving to bifurcate the lower part of the member 21 to providemlearance space fora member 29 now to be described.

The member 29 can be made of sheet metal bent to form two converging portions 30 and 31, the portion 3]. being curved adjacent its free end as shown at 32. The member 29 is adapted to swing freely on the pivot or hinge pin 25 and can be moved into a position as shown in Figure 2 and held by means of a spring 33. The snring 33 is in the form of a strip, one end of which is secured by the screw 23, while the other end is free. and ada ted to be engaged by the curved part 32 of t e member 29 so that during movement of the member 29, the part 32 will serve to defiect the upper curved end 34 of the spring until it passes thereunder, after which the latter will return to its normal position and hold the member 29 in the position asshown in Figure 2. It may be here stated that in order to again release the part 32 of the member 29, it is necessary to manually move the upper end 84 of the spring 33 to free the part 32, after which the member 29 can swing on the pivot pin 25.

The'material of the member 21 is preferably extended upward and bent to form a reenforcing guard and brace 37 for the lower end of the switch casing 12, this brace having its lower edge resting on the top'surface of the body portion 9 of the iron.

It will be noted, as clearly shown in Figure 1, that the member 29 when released from the sprin 33 can be positioned to rest upright on t e ironing board, the surface level ofwhich is indicated by the line 35, and by swinging the iron forwardly, of the base 27 will engage the portion 30-of the member 29 thereby supporting the iron with the ironing surface tilted forwardly, the

extent of tilting of the iron being suflicient to cause the gravitating member 19 to engage the abutment member 16 and thereby comlete an electric circuit through the lIOIl to eat the same. When the iron has been heated to the proper degree for ironing purposes, the

. operator by lifting the iron will allow-the member 29to swing downwardly and then by rocking the iron on the part 24 into the position shown in Figure 3, the part 32 will engage the spring 33 and become fastened so that the iron can then be movedintothe ironing position asshown in Figure .2. r

If for any purpose it is necessary for the operator to discontinue ironing, or if the operator is temporarily called away, it is merely necessary for her to tilt the iron on the portion 24 of the stand either into the position shown in Figure 3 or into the full line position shown in Figure 5 and the'iron 'will be supported in such rearwardly tilted osition andthe gravitating member 19 wil move within the tubular terminal 17 and out of engagement with the abutment member 16,

the rear portion thereby breaking the electric circuit and consequently discontinuing'heating of the iron. When in said latter position, the base 27 is held in a posit-ion remote from the ironing board and the iron will cool. When it is desired to again use the iron, it is merely necessary to release the member 29 from the spring 33 and allow the member 29 to be moved into the position shown in Figure 1 where it will again support the iron infa forwardly tilted position.

By shaping the parts as shown in Figure From the foregoing description and 'as illustrated in the drawing, it is obvious that it is unnecessary for the operator to rotate or cause the pushing of any switches if it is necessary for the operator to temporarily discontinue the ironing operation. The mere tilting of the iron rearwa dly will cause the discontinuationof the electric current and such a tilting action is an easy one to vperform and the operator will know that if she tilts the'iron rearwardly as above described that,

there is nothing to fear since the current is cut off automatically by such tilting and that; l the iron will cool.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with an iron of a stand including a portion providing a tilting support for the iron to hold the base clear of the ironing board, said stand having a hinged portion adapted to be swung forwardly under the base of the iron to suilpocrtlz tle bottom" y 1 to pos1 1011.

The combination of an iron; and 'a stand, said stand including a portion secured to the iron and projecting rearwardly to provide a rocking support, said stand also including a pivoted portion movable forwardly under the iron, said pivoted portion being bent to provide a raised support for the iron when swung forwardly thereunder.

4. The combination of an iron; and a stand, said stand including a portion secured to the iron and projecting rearwardly to provide a. rocking support, said stand also ineluding a pivoted portion movable forwardly under the iron, said pivoted portion being bent to provide a raised support for the iron when swun forwardly thereunder, the ivot connection eing so positioned relative y to 7. The combination of an iron; and 'a stand connected to the iron and having a pivoted portion adapted to swing under the iron and support the latter in a tilted position; and readily releasing means for holding said portion in a position out of the way of the bottom ironing surface when the iron is being moved for ironing purposes.

In testimony whereof, I have signed my 20 name to this specification.
