HAIR-DUBLING DEVICE.

Application filed March 3, 1926.

The present invention appertains to improvements in hair curling devices of the tong class generally, and particularly to that type disclosed in my prior Patent No. 1,293,304 of February 4-, 1919 wherein is provided a removable heating rod enclosed in a protective shell to prevent its direct contact with the hair.

In the common form of curling iron, speaking more particularly of the nonelectrical type, the mandrel element or jaw is subjected to direct contact with the fiame when heating the same, and in this process a certain amount of soot adheres to this member. It is necessary, under such condi-,

tions, to wipe the surface of the member to remove the deposit before proceeding with the curling operation, but because of the heat, this cleaning process is usually carelessly done, 'with the result that the soot is transferred to the hair. The heating operation, furthermore, tends to destroy the high finish of the mandrel, and this interferes to a certain degree with the manipulation of the iron with respect to the hair.

However, the greatest objection to this type of curling iron resides in the tendency to scorch the hair because of the inabilityto control the degree of heat to a certainty or determine the length of time of the application'of the heat to the hair, to overcome which the iron is generally under-heated, thereby unduly prolonging the time of the curling operation. The scorching of the hair is so frequently the result of the use of this type of device that I have endeavored to eliminate such disadvantages by employing separate heating element suclras disclosed in my prior patent above referred to. I have found, however, even in this form that 'too much heat is transmitted to the mandrel and this has led me to devise the present improvements, the characterizing novelty of which resides in the provision of a heating rod which is substantially smaller in diameter than the enclosing sleeve or hollow member, so as to practically eliminate direct contact between these parts. The heat is thus indirectly transmitted to the shell and no danger of burning is encountered in its use.

My present invention otherwise presents novel advantages over the prior construction in the form and arrangement of the connec tion between the shell and the handle sup- Serial No. 92,015.

Like reference characters designate corresponding parts throughout the several figures of the drawing. 7 In the drawing, 1 designates a sleeve or housing which constitutes the mandrel around which the hair is usually wound in this type of curler, said sleeve being preferably closed at one end and open at its other end to receive the heating rod 2. The cooperating concave spring actuated arm or clamping member 3 is pivotally mounted at 4 on the sleeve and terminates in the offstanding manipulating linger piece 5. As a detail of constructioi'i, I prefer to provide openings 5 in this piece so as to keep the part as cool as possible.

The rod 2,as hereinbefore stated, is sub stantially smaller in diameter than the sleeve 1 and only contacts with the same at the tip end for the purpose of holding the rod centered in the sleeve or housing. The extent of contact of metal to metal, however, is reduced by grooving or otherwise ap-ering the tip of the'rod as indicated at 2 to form one or more pointed prongs, the

points only of which touch the sleeve for which is secured thereto by the pivot 8, this construction and arrangement providing a longitudinal slot 9 into which a diagonal or spiral groove 10 in the connector piece leads. The end of the sleeve snugly fits the shank iece 6 and a projection 11 formed by stamping the metal of the sleeve inwardly by a sharp instrument is designed to cooperate with the groove 10 to lock the sleeve in operative position 011 the handle. That is to say, when the rod 2 has been heated, it is straightened into alignment with the shank piece and the sleeve then slipped thereover in such a way that the protuberance 11 will pass down the slot 9 until it reaches the end of the groove 10, whereu on the sleeve is turned to pass the protu erance into said groove, which, owing to its spiral arrangement causes the sleeve to be pulled tightly against the end of the handle. It is thus rigidly held during the use of the curling iron. A slight turn of the sleeve, the finger piece 5 being utilized as the handle means for this purpose, enables the detaclnnent or displacement of the clamping men'ibers with relation to the handle and the heating rod.

The pivotal mounting of the rod 2, a feature of my prior patented construction, enables the swingingof the same into an angular position with reference to the handle,

a distinct advantage in the heating operation, and preferably a spring 12 is provided to coact with the pivoted end of the rod to hold it in the various positions.

It will be obvious from the foregoing, however, that the application of the sleeve in the manner above described locks the rod in its aligned position with respect to the connector piece, a feature which is a decided improvement over the arrangement of my prior patented device.

This construction is therefore considerably simplified and I desire it to be particularly understood that I do not wish to be confined to this particular type of heating device as the principles are equally applicable to Marcel wavers and the like.

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

1. A hair curling device of the class described comprising a hollow member, and

a heating member disposed within and spaced from the hollow member to thereby indirectly heat the latter and having at its free end prongs to engage the end of the hollow member to center the heating member therein.

2. A hair curling device of the class described comprising a handle, a heating member pivoted on the handle for lateral movement, a hollow member movable longitudinally upon the heating member to enclose its pivot, and means on the handle interlocking with the hollow member to hold the lat-- ter rigidly thereon and prevent movement of the heating member.

3. A hair curling device of the class described comprising a handle, a heating member pivoted to a connector from the handle, and a hollow member movable longitudinally upon the heating member and closely fitting said connector to enclose the pivot and prevent movement thereon of the heating member.

4. In a hair curling device of the class described, a hair receiving member, a heating element therefor spaced from said member,

movement of the rod.

6. A curling device of the class described comprising a sleeve, a heating rod removably disposed therein, a handle, and a shank piece pivotally connecting the rod to the handle, said shank piece receiving the sleeve in position engaging over the pivotal connection of the rod therewith to maintain'the rod against movement with relation to the handle.

7 A curling device of the class described comprising a heating rod, a handle therefor, a connector pitc'e for connecting the rod to the handle and having a groove therein, a hollow hair receiving member enclosing said heating rod and having means enga eable with the groove aforesaid to lock said hollow member in position over the rod by a sliding and rotative movement of said means.

In testimony whereof I aflix my signature.
