GEORGE D. POGUE, OE JERSEYVILLE, ILLINOIS.

ELECTRIC HEATER FOR CURLING-IRONS.

SPECIFICATION forming part of Letters Patent No. 549,152, dated November 5, 1895.

Application led March 29, 1895. Serial No. 543,650. (No model.)

To all whom it may concern:

Be it known that I, GEORGE D. POGUE, of Jerseyville, in the county of Jersey and State of Illinois, have invented a new and useful Electric Heater for Curling-Irons; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an electric apparatus for heating curling irons, my object being to provide a simple and inexpensive heater that can be placed upon a ladys toilettable, and being connected with the feedwire of an ordinary incandescent lamp or any other suitable electric source will quickly heat the curling-iron, and, further, to so locate the several parts of my device with reference to each other that the electric circuit shall be automatically closed by the insertion of the curling-iron in the coil of the heater and opened by its withdrawal.

With these ends in view my device consists in certain details of construction and combinations of parts fully described in the following speciiication, and illustrated in the accompanying drawings, in which-.

Figure l is a side elevation of the apparatus shown in connection with a curling-iron in position for heating. Fig. 2 is a plan View of the same; and Fig. 3 is a vertical longitudinal section of the heater, taken through the center of the coil.

Referring to the drawings, A represents a wooden base-board, and B an electric heatingcoil, the several layers of which are wound around the core alternately in opposite directions-that is to say, one layer to the right and the next to the left in reciprocal succession. The advantage secured by such winding is that the coil is thereby adapted to either direct or lalternating systems, the current flowing being dependent on the ohmic resistance only and in the case of an alternating current is not influenceduby self-induction, as would be the case if the coil were not wound as above explained. C is a metallic tube forming a hollow core to the said coil and located longitudinally in the center thereof, as shown, said core being secured in and supported by metallic standards d d, which are secured to the base-board.

Located near the right-hand end of the base-board are two metallic posts S S', to the top of cach of which is secured a metallic spring-clip c and c', the free ends of which are so shaped as to forni together two segments of a circle adapted to clip the cylindrical body of the curling-'iron when placed in the tube C.

It will be observed by reference to Fig. 3, in which the path of the electric current to and from the coil is indicated by arrows and the positive and negative conducting-wires are respectively designated by the usual symbols, that the tube O is the positive terminal of the wire r, which is connected with the electric source, and enters the left-hand end of the base-board. This isaconsequence of the positive wire being where it leaves the coil, as shown at r', in electric connection with the standard d and the latter in electric connection with the tube O. Now it will be observed that the clip c being electrically connected through the post S with the return or negative wire fr", it follows that the said clip becomes the terminal opposite to that which is formed by the tube C. Therefore, to close the circuit it is only necessary to electrically connect together the clip c and the tube C, which is automatically done by passing the curling-iron through the clip c into the tube O, the opening of the circuit being effected by the reverse operation.

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

' In an electric heater, the combination of a heating coil, a hollow metallic core on which the coil is wound, one end of the latter being electrically connected with the said core so that the latter will form one of the terminals, a support for the article to be heated, so secured in position with relation to the coil, and so connected with the opposite line wire as to form the opposite terminal, so that the implement to be heated, will, by resting upon the support and the interior of the core of the coil, close the circuit, all of said parts constructed, combined, and adapted to operate substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 13th day of March, 1895.

GEORGE D. POGUE.
