3 Claims.
e present invention relates generally to electric heating-devices but more particularly to a flat iron heated by induced current.
One object of the invention is to provide an electrically heated iron with which it is unnectherehypermitting manipulation by the Another object of greater speed and ease of operator.
mary coil in said plate.
It is a further object of this invention to provide an iron having an inductively energized and efdcient in heat.
With these and other Referring to the figures in which like parts are indicated by similar reference characters- Fig. l is a side elevation of the iron partially sectionized on the line 2f-2 of Fig. 2;
Fig. 2 is a bottom plan view of the iron shown in Fig. i with the sole plate removed;
3 is a. sectionized view taken on the line of en. 1;
of the iron support switches, lead-in wires; view of the iron sun of Fig.
iron support showing the rotary switch and connecting terminals;
Fig. 9 is a diagrammatic sketch partially in (Cl. 2l925) (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 757) till perspective, showing the laminated core, the primary and connecting leads to the switches, and to the power circuit plug.
when not being used, the stand containing a primary coil energized from an electric light circuit, and the flat iron secondary rings which are inductively energized by the coil.
Referring to Figs. 1 to 3 inclusive which illustrate the construction of the iron, the numeral Hi indicates the sad iron and of the laminated plates is surrounded by the primary coil 27, one end of which is connected to a lead 28 of an electric light c'mcuit. The turns of the coil are'connected at various lengths to switch terminals- 29", 35', 3t, 3'2 and through lead-wires 29', and The switch terminals are arranged arcuately around the pivotal point of a switch blade which is connected to the terminal 515 of an automatic switch 36 by a conductor 3?.
The automatic switch 36 comprises a elevated depressihle member 38 which. retained; in elevated position by means of a spring contact member The spring contact member whichis mounted upon an insulating plate an attached to the stand, is connected through terminal to the conductor 3? and is adapted when depressed to normally M to the electric not bein used to pressible member within the sad iron.
To operate the iron it is placed upon the stand in which position it depresses the automatic switch to energize the primary coil 2'1, the degree of energization being controlled by the rotary switch. By induction the primary coil 2? energizes the secondary rings in the sad iron thus generating heat within the core which is transmitted to the sole 12. After the sad iron is sailiciently heated it is removed from the base by the operator if or pressing purposes.
Having described my invention, as new and wish to secure by Letters Patent is:
l. A device of the character described comprising a flat iron including a solo, a shell, and a handle, a laminated core enclosed within said shell, said core having three downwardly projecting members, secondary rings surrounding said members adjacent said sole; and a stand adapted to support said iron, said stand comprising a casing containing a laminated core enclosed within said casing, said core having three upwardly projecting members, a primary co'l surrounding said central member, and means comprising a pressure operated switch and a rotary switch attached to said stand adaptedto connect said primary coil with a source of power when the fiat iron is placed upon said stand and to regulate the energization-thereoi to thereby control the temperature of said iron 2. A device of the character described comprising a flat iron including a sole, a shell, an insulating lining within said shell, and a, handle, a laminated core enclosed within said shell, said what I claim tached to said aereecz bers, secondary rings surrounding said members} adjacent said sole; and a stand adapted to sup: port said iron, said stand comprising a casin an insulating plate mounted within said casing, a laminated core mounted upon said insulating plate, said core having three upwardly projecting members, a primary coll surrounding the central member of said core, means comprising a pressure operated switch and a rotary switch atstand adapted to connect said priof power when the fiat iron is placed upon said stand and to regulate the energization thereof to thereby control the tem: perature of said iron.
3. A device of the character described comprising a flat iron including a sole, a shell, an insulating lining within said shell, and a handle, a laminated core enclosed within said shell, and insulated therefrom, said core having three downwardly projecting members, secondary rings sur-= rounding said members adjacent said sole, and a stand adapted to support said iron, said stand comprising a casing, an insulating plate mounted within said casing, a laminated core mounted upon said insulating plate, said core having three upwardly projecting members spaced equally and corresponding in alignment with said three downwardly projecting members of the core enclosed within the shell of said iron when the iron is supported upon said stand, a primary coil surrounding the central upwardly projecting member of the core within said stand, and means comprising a pressure operated switch connected with said stand adapted to connect said primary coil with a source of power when the iron is placed upon said stand.
