ELECTRICALLY-HEATED SADIRON.

Application filed ()ctober 20,- 1924. 4 Serial No. 744,790. I

To all whom it may concern Be it known that I, HERMAN GANsnRT, Jr., of Syracuse, in the county of Onondaga, in the State of New York, have invented new and, usefollmprovements' in Electrically-Heated Sadirons, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to an electrically heated cordless sad-iron, but refers particularly to a supporting standand means for conducting the current to the heating element within the sad-iron when resting on the stand.

The current conducting means most commonly employed involves the use of a flexible cord having one end plugged into a suitable socket. containing terminals of an electric'source of sup ly and its other end provided with a coupling relnovably adapted to suitable terminals on the sad-iron in electrical'connection-with the heating element therein, so that during the launderin op eration the flexible cord attached irectly to the sad-iron must move back and forth with the various ironing movements resulting in considerable inconvenience to the-operator and frequently straining the connections to such an extent as to break the conductor at some point in its length, usually near the coupling.

Furthermore, it is well known that many fires have occurred as a result of settin the sad-iron aside for greater or. less perio s of time frequently upon a wooden support, such as an ironing board, without disconmeeting it from the source of currentsupply and that in many instances garments have been destroyed. by overheating of the sad-iron duringthe ironingoperation.

The main object of my present invention is to provide what may be termed a cordless sad-iron by connecting the flexible con ductor leading from the source of supply directly to a metallic support or stand upon which the sad-iron is adapted to rest when not in use and to provide said sad-iron and support with separable switch contacts as a part of the conducting means between the source of current supply and the heater, whereby when the sad-iron is placed upon the sup orting stand, it will make electrical connection with the conductor leading to the support while, on the other hand, when the sad-iron is removed from. the supporting stand the electrical connection with the conductor will be broken.

Another object is to provide the heater terminals of the sad-iron with a switch cap which, when placed in operative position, is adapted to make and break electrlcal connection with cooperative contacts on the support but may be removed to permit the coupling to be attached directly to said heater terminals in the event that the operator may choose to maintain connection with the source of current supply during the ironing operation, thereby afi'ording an alternative choice between the two methods. A further object is to provide the sadlron support with an electro thermostatic switch forming a part of the current conducting means whereby the heat circuit may be automatically broken in case the temperature of the sad-iron exceeds a predetermined degree.

Other objects and uses relating to specific partsot the device will be brought out in the following description.

In the drawings:

Figure 1 is a perspective view of an electrically heated sad-iron and a support there for, together with the adjacent portion of conducting cable and coupling adapted to be connected to a source of electrical su ply for su plying current to the heater within the sa -iron.

Figure 2 is an enlarged detail sectional view through a portion of the sad-iron stand or support and adjacent portion of the sadiron thereon, taken on line 22, Fi ure 1, showing portions of the electric swltch in operative position for supplying current to the heater inathe sad-iron.

Figure 3 is a detail sectional View partly diagrammatic taken in the planes of line 3-3, Figure 2.

The sad-iron as A. may be of any ,well known construction containing a suitable electric heater having a pair of terminals 1- projecting upwardly and rearwardly from the heel of the sad-iron and rotected from contact with external obects by a shield 2, preferably of metal, which is also fastened to the heel of the sadiron to extend continuously around and in spaced relation to the terminals -1-.

Under these conditions, the current will pass fromflonew of "the terminals -20 through the corresponding bracket --18- and its 1 contact roller 16- and thence through the adjacent contact member 1l-- to one side of the heater coil a, thence through the other contact member .l1.

This automaticcontrol of the circuit to the heater in the sad-iron maintains a uniform temperature of said sad-iron while supported upon the stand 3.

When the sad-iron is removed from the stand for ironing purposes, the switch member -10-- is, of course, withdrawn from contact with the roller members 16 thereby breaking electrical connection with thesource of supply and assuring a safe heat to the sad-iron during the ironing operation.

It is, of course, understood that these ironing operations are intermittent and that the sad-iron is replaced upon the stand immediately following such operation which is ordinarily sufiicient to keep the iron at the desired temperature.

An electric fiat iron stand comprising a support for the iron, spaced contact members of anelectric heating circuit mounted on the support, and an additional contact member of the same circuit movable into and out of contact with the first-named members for making and breaking the circuit and provided with sockets for receiving terminals of the heater circuit on the fiat iron, said circuit including therein a thermostatic switch mounted on said support.

bers for making and breaking the circuit and provided with sockets for receiving terminals of the heater circuit on the flat iron, said circuit including therein a pair of terminals mounted on the support for connection to a source of electric supply.

3. An electric flat iron stand comprising a support for the iron, an electric switch and terminals, both connected in the heating circuit, one of the switch elements and the terminals being mounted on the support, the other switch element being movable into and out of contact with the first named element and provided with means for contacting with the heater circuit terminals on the sad iron,
