UNITED STATES GEORGE R. BLAKESLEY, OF EDGERTO'N, WISCONSIN.

ELECTRIC IRON.

Application filed December 2, 1929. Serial No. 427,668.

To all whom it may comm:

Be it known that I GEORGE R. BLAKES- LnY, a citizen of the United States, and a resident of the cit of Ed ert0n, 1n the county of Rock and tate of lSCOIlSlIl, have invented certain new and useful Improvements in an ElectricIron; and I dohereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawlngs, and to the numerals Ofreference marked thereon, which form a part of this specification.

My invention relates to an electric flat iron for ironing clothes and more particularly with reference to the electric switch whereby the current is turned on and oil.

It is an object of this invention to provide a switch for an iron so constructed and located that it can be manipulated by a finger of the hand that holds the iron.

It is also an object of this invention to provide a simple and easily operated structure for attaining the above Ob18Ct.

Other and further important objects of this invention will be apparent from the disclosures in the specification and drawin s.

lhe invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a section through a fiat iron showing the construction of the switch mechanism.

Figure 2 is a view on the line 2-2 of Figure 1 looking upward.

Figure 3 is a section on the line 38 of Figure 1.

As shown in the drawings:

In the difi'erent figures of the drawing, similar features are denoted by similar reference characters.

As shown in the drawing, the flat iron per se is of substantially the usual construction having the ironing base 1, directly above which is the insulation 2 through which the resistance wires or coils extend, and above the insulation is the body 3 having a plurality of bores to receive the projectingbosses 4 on the ironing base 1. The body 3 1s'preferably covered with asbestos 5 and screws 6 extend through the asbestos, the body and into the bosses for holding the parts together. A sheet metal housing 7 soldered or welded to the base 1 encloses the body 3 Y and extends thereabove to provide a space for the switch mechanism, the upper wall of which serves as a longitudinal support for the switch mechanism, and the usual handle 8 is secured to the upper wall or longitudinal support by means of the standards 9 bolted thereto as is common in the art.

In the space between the top of the asbestos 5 and the top wall of the housing 7, I locate my switch mechanism which issupported from the top wall of the housing. In the present embodiment of my invention, I contemplate using a knife switch 10 secured on the operating lever 11-wh1ch is pivotally mounted on a lug extending downwardly from the top of the housing. The switch lever 11 extends throu h a slot in the housing and to a point within easy reach of a finger of the hand that grasps the handle 8. The knife switch 10 is adapted to 18. It will therefore be obvious that when the knife edge 10 is inserted between the two pairs of spring clips, the circuit will be completed. In order to hold the knife switch 10 in inoperative position so that it may not dangle into contact with the spring clips, a coil spring 18 is connected to the lower end of the lever and to the upper wall of the housing 7, and to rigidly support the upper wall of the housing 7, a screw 19 may extend therethrough and be anchored in the body 3.

In using a flat iron involving my invention, it is only necessary to grasp the handle with one hand and swing the switch lever 18 with a finger of that hand into operative position to complete the circuit, and at any time the current may be turned off by throwing the lever 11 to inoperative position by a fipger of that hand which grasps the hand e 8.

It will accordingly be observed that I have embodied in a flat iron a readily operable switch mechanism which is conveniently located so as to be operable by a finger of the hand that does the ironing.

I am aware that numerous details of con struction may be veried' through a wiole range Without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

In an electric sod iron, on ironing mom her, a housing seeureol thereto and extendiing thereebove, o switch supportecl in small lions ing, a switch lever ivoted; to seicl housing edgeoent suiol switc and extending there-
