ANDREW D. GARDNER, OF LYNN, MASSACHUSETTS.

ELECTRICAL CURLlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 484,532, dated October 18, 1892.

Application filed October 2l, 1891. Serial No. 409,404. (N o model.)

To a/ZZ whom it may concern-.-

Be it known that I, ANDREW D. GARDNER, a citizen ot' the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Electrical Curling-Irons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in curling-irons; and it consists in the construction and arrangement of parts hereinafter described, and definitely pointed out in the claims.

The object of -my invention is to construct a curling-iron with suitable electrical connections, so that the iron may be heated by the passage of a current through the connections. This object I attain by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate like parts in both the views, and in which- Figure l is a perspective view of my device, and Fig. 2 is a longitudinal section thereof.

In the drawings, A represents the handle, constructed of any suitable non-conducting material, such as rubber, porcelain, or glass. This handle has a central bore B and a hollow curling-stem C. This stem is made of metal, with thin walls anda closed outer end, its inner end'being enlarged, as at C', and united with the handle in any suitable manner. On the stem C is pivoted the crimpingjaw D, which is concavo-convex in cross-section and is pivoted to the ears D', extending out from the stem. The rear portion of the jaw has the lever-arm Eextending out therefrom, which is provided with a rubber or other suitable non-conducting thu mb-piece F.

G and G" represent two wire conductors extending through the bore of the handle, their outer ends being connected to bindingposts H Il', while their inner ends are united with the ends of a resistance-coil K. The coil K is doubled or has two parallel sides coiled spirally and parallel with each other, the outer end being in the form of a loop and located in the extreme outer end of the stem,

the inner end being united tothe wires G G at the base or enlarged portion of the stem. The resistance-coil is placed directly in the center of the stem, so that when it is made incandescent the heat radiated therefrom will heat the stem equally throughout.

On the butt-end of the handle I place a suitable removable cap L, projecting over the binding-posts and through which the wires pass. This cap is intended to prevent the accidental separation of the conductors M from the binding-posts to which they are attached. The conductors M lead from any suitable source of electricity.

It is to be understood that I may vary the size of the curling-iron and the length and position of the lever, so that the curling-iron may be used for curling the hair of the mustache, for which it is particularly adapted, or hair of any other description.

I am aware that many minor changes in the construction and arrangement of the parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.

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

1. In a hair-curling iron, the combination, with a hollow insulated handle, of a hollow cylindrical curling-stem on the handle formed with thin metallic walls, means for heating the stem, consisting of a wire arranged within and coiled spirally in the curling portion of the stem, electrical conductors with which said coil is connected, and a jaw engaging the stem having an insulated thumb-piece thereon, substantially as described.

2. In a curling-iron, the combination, with an insulated handle, of a hollow metallic curling-stem, electrical conductors in the handle, a looped resistance-wire within the stem, having its respective branches coiled parallel with each other and connected to the conductors, and a jaw on the stem, having an insulated thumb-piece, substantially as described.

3. In a curling-iron, the combination, with an insulated handle, of a thin metallic stem having a hollow center, a resistance Wire IOO coiled in the stem,e1eetrica1 eonductorsin the handle with which the resistance-Wires are connected, binding-posts on the handle, a removable perforated cap on the handle over 5 the posts, and electrical conductors passing through the cap and secured to the posts, substantially as described.

In testimony whereof I ax my signature in presence of two Witnesses.

ANDREW D. GARDNER.
