CURLlNG-lRON.

SPECIFICATION forming part of Letters Patent NO. 404,127, dated May 28, 1889.

Application filed July 24, 1888. Serial No. 280,893. (No model.)

To all whom it may concern/.-

Be it known that I, GEORGE L. THOMPSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Curling-Irons; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an in'lprovement in cnrling-irons of that class embracing a cylindric metal rod or mandrel provided with a handle at one end, and which is used by heating the mandrel and then wrapping the hair about the same.

The invention embraces an improved means for connecting the metal mandrel with the handle,whcreby the transmission of heat from the mandrel to the handle is prevented or lcssened, and it also embraces an improved construction in a spring-clasp for clasping the end of the lock of hair to the outer surface of the mandrel to facilitate the holdin g. of the hair while being wound thereon,

A curling-iron embodying the main or prin cipal features of my invention is provided with a handle, a mandrel, and a tube connectin g the handle and mandrel, such tube-conned tion preventing the passage of the heat from the mandrel to the handle, while at the same time affording a suitably-rigid connection between the parts and giving a neat finish to the article as a whole.

In the accompanying drawings, illustrating my invention, Figure 1 is a side view of a curling iron embodying the main features of my invention. Fig. 2 is a central longi tudinal section thereof. Fig. 3 is a detail sectional view showing a modified form of the recessed connection wherein the latter consists of a tube provided with a non-conducting filling.

As illustrated in Figs. 1 and 52, A is a mandrel, preferably made solid and of metal and cylindric in form.

B is a handle; 0, atube connecting the mandrel and the handle; D, a spring-clasp, pivoted by means of a pivot'pin, (Z, to the tube 0, and provided with a thumb-piece or handle, D, to whichis attached a leat-sprin g, d, which bears upon the adjacent surface of the tube and tends to hold the clasp in contact with the mandrel. The tube 0 is desirably made of the same exterior diameter as the mandrel, and is fitted over the end of said mandrel and secured thereto by a rivet, c, in a manner clearly shown in Fig. 2. A screw-joint or other connection may, however, be made between the parts with practically the same result. Said tube is shown as secured to the handle by rivet 0; but any other convenient means for connecting these parts may be used in practice, as desired.

The purpose of the tube C connecting the mandrel and the handle is to prevent the transmission of the heat to the handle when the mandrel is heated for curling the hair, it being entirely obvious that if the mandrel were made in one solid piece of metal reaching to or into the handle, as similar curling-irons have been heretofore made, the heat would be rapidly transmitted to the handle, thereby making the same uncomfortably warm for the hand, or might char the handle. The said tube 0 illustrated is shown as provided with a number of air holes or apertures, c 0 0 which lessen the area of the tube through which heat may be transmitted, and serve to admit air to the interior of the tube, thereby tending to keep the latter cool.

The pivot (I of the spring-clasp D is illustrated as inserted through the tube O, and the spring (1 as arranged to bear upon said tube. The said spring arranged to engage the tube, instead. of the mandrel proper, in order that the spring may be heated as little as possible. It is specially desirable that the spring should come in contact with the tubular part only, for the reason that in case that spring is in direct contact with the mandrel the heat of the latter is liable to transmit to the spring a suhicient quantity of heat to affeet its temper,

The employment of. a tube as a means of connecting the mandrel and the handle posscss important advantages in point of neat ness and smoothness of finish and cheapness of manufacture, and an implement constructed with a tubular connecting part is therefore herein specifically claimed as part of my invention.

The hair-curler constructed as above described is employed in the usual manner by first heating the mandrel to a desired temperature and clasping the end of the lock of hair between the spring-clasp and the mandrel, and thereafter revolving the handle so as to coil or wrap the hair about the-mandrel and clasp. The said clasp shown in Figs. 1 and 2 is desirably made of sheet metal bent into concave form to fit the surface of the mandrel and having downwardly-bent marginal ears d to receive the pivot-pin d.

I have herein shown the mandrel of the curling-iron as being made solid and of metal. Such mandrel may, however, be constructed entirely of other substance-as, for instance, soapstone-crit may be tubular and of s-u'ffi-i 'cient thickness toretain heat a suitably long time for effective use; orit maybe a thim metal tube provided with a filling of pulver-l ize'd refractory" material, such as has hereto-i fore been used for similar purposes.

The construction herein described relating? to the =me'a-ns for connecting the ma-ndrel} which is' to be heated with a handle may be employed 'as'well in connection with the metal rod or core of the curling-iron shown:

- in prior Letters Patent,'No.-36l,682, issued to other similar substance having little capacity for conducting heat.

As a 'furtherandseparate improvement in curling-irons having spring-claspsy I place between the'handleD' of the clasp and the spring 'd a piece or layer, d Fig.2, of asbestus' paper or other material which is a non-conductor of heat, such layer pr'eventin g the rapid passage of heat from the handle to the spring. The rivet which secures the spring to the handle is shown as passing through the said layer, thereby holding the the'said non-conducting piece or layer d above described.

I claim as my invention 1. As a novel article, a curling-iron consisting of a mandrel, ahand-le, and a tube 'for uniting the handle and mandrel, said tube being attached to the handle and fittedover the end ofthe mandrel and permanently secured thereto, substantially as described.

2. As a novel article, a curling-iron consist. ing ota m andrel ,'-a handle, and an apertured 1 tube for uniting the handle *and mandrel,

which is attached to the handle and is fitted over the end of the man-dreland permanently secured thereto, substantially-as described.

3. A curling-iron com-prising a'inan'drel, a

'handle,-a-tube connecting the sameyand a spring-clasp pivoted to the said tube, substantially as described.

4. The combination, with a mandrel and a handle, of a tube connecting the handle and mandrel, a spring-clasp pivoted to said tube, a leaf-spring attached-to the handle of the clasp and bearingon the tube, anda piece or layer-of non-conducting nnaterial placed between the handleand spring, substantially as described.

In testimony that I claim the foregoing-as my invention I afiix my signature in; presence oftwo witnesses.
