COMBINED CURLING-IRON AND WATER-BOTTLE HEATER.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed February 12, 1918. Serial No. 218,707.

To all whom it may concern:

Be it known that I, HERBERT W. CHRIS- TIAN', a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Combined Curling-Iron and Water-Bottle Heaters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a combined curling iron and water bottle heater, and the invention, in its broadest aspect, comprehends a heating element or unit that may be used as a stationary member of a hair curling iron, or in a water bottle or receptacle for heating the contents thereof. To this end, I have devised a heating unit which may be used as the stationary or heated element of a hair curling iron or device, and then removed and placed in a water bottle or receptacle to heat the contents thereof, the heating unit being adapted for direct or alternatin lighting circuits with a novel rheostat whic permits of the user of the hair curling iron or hot water bottle cutting in or out a desired amount of electric current to produce a desired temperature, either of the curling iron or .the water in the bottle or receptacle. It is in this connection, that the rheostat which may be easily and safely adjusted permits of the user of the hair, curling iron maintaining a desired heat in connection with the same without any danger of the hair being burnt or otherwlse injured when curled on the iron. In connection with a hot water bottle or similar receptacle, it is also possible to maintain, indefinitely, a desired temperature of the contents of a hot water bottle or receptacle, and this is particularly advantageous during the night use of a hot water bottle, as it prevents the water from becoming cold and maintains a desired treatment or application of heat throughout the night, without changing the water in the bottle.

The many advantages of the invention are too numerous to be herein set forth, but will be apparent as the invention is better understood, and reference will now be had to the drawlngs, wherein Figure 1 is an elevation of a portion of an ordinary water bottle, showing the heating element therein and connected with a rheostat and a suitable source of electrical energy Fig. 5 isa diagrammatic view of the heatmg element and rheostat, showing the elec-' trical connections therebetween.

In descrlbin my invention by aid of the views above re erred to, I desire to point out that the same are mere-1y illustrative of the device aS now in use, and I do not care to confine my invention to the precise construction and arrangement of parts shown.

In the drawing, the reference numeral 1 denotes a tubular heating element or unit containing the usual amount of insulation and resistance coils, and at the inner end of said heating element is a screw socket 2 connected to a cable 3 so that an electric current may be conducted through the heating element. The cable 3 is adapted to be connected to anordinary electric light lamp socket 4 or any source of electrical energy. and as shown in Fig. 1, the screw socket 2 is mounted in the mouth or neck 5 of a water bottle or receptacle 6, with the heating element 1 extending therein to heat the water or contents of the bottle. To prevent the inner end of the heatin element from injuring walls of the water bottle 6, the end of the heating element may be provided with a cushion member 7, either in the form of a spring, piece of rubber or similar material.

As shown in Fig. 4, the heating element 1 may extend through a handle 8 with the screw socket 2 in the outer end thereof and serve as the stationary member of a hair curling iron which has a pivoted channel shaped member 9 normally in contact with the heating element, but movable to and from said element so that hair may be clamped between the element and the member 9. The member 9 is of a conventional form having the inner end thereof provided her relative to the movable member, of the iron. It is a fact that the water bottle 6 may be used without the heating element, but it is impossible to maintain the water within the bottle at a uniform temperature without having the heating element therein.

To regulate the temperature of the heating element, either in connection with the hair curling ironor with the water bottle, I have devised a simple and compact rheostat that may be embodiedin the cable 3. This rheostat comprises two circular heads 12 and 13, preferably made of fiber, and connecting said heads are tie rods 14 and 15 on a contact holder 16, referably made of fiber or a suitable insu ation material. On the rod 15 is a core 17 and about said. core is a resistance coil 18 having lead-out wires 19 to contacts 20 carried by the insulated holder 16. The resistance coil is connected by a wire 21 to a binding post 22 of the head 13 and said binding post is connected to one of the wires of the cable 3.

Slidable on the rod 14 is a guide sleeve 23, preferably in the form of a coiled rod, and one end of the sleeve or rod su ports a contact member 24 that may be shi (1 over the contacts 20 to cut in and out resistance. The opposite end of the sleeve or rod terminates in a knob or handle portion 25 that extends through a longitudinal slot 26 provided therefor in the wall of a cylindricat casing 27 mounted 'on the heads 12 and 13. A knob or handle 28 is fitted on the portion 25 of the sleeve or rod to slide in the slot 26, and a wall of said slot is notched, as at 29, so that that portion of the knob or handle within the slot 26 may recede into the notches and thereb indicate that the contact member 2Q is m engagement with one of the contacts 20. It is-furthermore preferable to make the sleeve or rod 23 of resilient material, whereby there will be a certain amount of resiliency or spring in the ends of the rod, thus maintaining the knob or handle 28 against the notched wall of the slot 26 or in the notches 29 thereof, while the opposite end of the rod will cause the contact member 24 to bear against or positively element.

The cylindrical casing 27 of the rheostat is provided with a series of openings 34 to prevent overheating.

It is thought that the operation and utility of the heating element will be apparent without further description, and it is to be understood that it may be embodied in hair curling irons of various types and also used in connection with various kinds of receptacles for heating the contents thereof.

What I claim is 1. As a new article of manufacture, a hair curling iron having a handle, a movable member and a detachable heating element adapted to be removed from the iron, and means carried by the outer end of said heating element adapted for attaching it to the handle of the curling iron and also to a receptacle for heating the contents thereof.

2. -A haircurling iron comprising a bandle having a movable member, and a detachable electrically heated stationary member screwed in said handle and against which said movable member is normally held.

In testimony whereof I afiix my signature in the presence of two witnesses.
