CURLlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 438,295, dated October 14, 1890.

Application filed May 10, 1889.

To @ZZ whom t may concern:

Be it known that I, GEORGE L. THOMPSON, of Chicago, in the county of Oook and State of Illinois, have invented certain new and use ful Improvements in Curling-Irons; and I do herebydeclare that the following is afull, 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 improvement in curling-irons of that class embracing a metal mandrel, a handle attached to the same, by which it may be manipulated, and a clasp for securing the-hair to the mandrel.

The invention embraces improved features of construction by which the heat is prevented from passing from the bodv of the mandrel to the hand of the userv when the mandrel is heated for use, and in other details of con struction in such curling-irons.

The invention consists in the matters hereinafter described, and pointed out in the appended claims.

As shown in the accompanying drawings, Figure l is a side View of a curling-iron constructed in accordance with my invention. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a detail face view of the clasp-handle.

As illustrated in the drawings, A is the mandrel, which is made solid and of metal, and cylindric in form, and B is the handle, which is preferably made of wood and provided with a ferrule b.

O is a clasp, which is made of thin or sheet metal and is convex in form, to fit the adjacent surface of t-he mandrel. Said clasp is pivotally connected with the mandrel by means of a pivot-rod c, inserted through the said mandrel and through ears c c on the clasp, and is provided with a handle O, the clasp being held against the mandrel by a leafspring O2, secured to the mandrel near the handle and bearing outwardly upon the said handle C. The spring is attached to the mandrel by being inserted at its end in an oblique slot d in the mandrel, the metal of the mandrel being hammered or otherwise closed down upon the end of the spring, so as to strongly secure the latter in place. The slot a is preferably so located that it is covered and Serial No. 310,250. (No model.)

concealed by the handle when the parts are assembled, as clearly shown in the drawings.

D is a plate or button of some non-metallic substance which is a poor conductor of heatsuch as vegetable or natural ivory, leather, or paper-which is attached to the handle C in position to receive the pressure of the nger in operating the clasp. The said plate or button serves to prevent any heat which may pass through the handle from burning the finger. rIlhe plate or button D maybe attached to the handle in any convenient manner, the device for that purpose herein shown consisting of a rivet d, having a forked inner end which is inserted in the body of the button. The non-conducting plate or button D is shown but not claimed in a prior application, Serial No. 291,342, led November 20, 1888.

In order to lessen as far as possible the pas sage of heat from the mandrel along the handle C of the clasp, the said handle is provided with perforations c2 c2 c2, by which the strength of the handle is notmaterially lessened while conductivity to heat is decreased.

In some instances the presence of the perforations in the handle may enable the nonconducting button to be dispensed with, but commonly such button will be employed, inasmuch as the handle is under some circumstances liable to become so highly heated as to be uncomfortable to or burn the fingers, even when such perforations are present.

I claim as my invention-e l. The combination of a mandrel of metal and a clasp pivoted thereto and provided with an integral handle perforated to lessen or retard the passage of heat therethrough, substantially as described.

2. The combination of a metallic mandrel, a clasp pivoted thereto and having a perforated .integral handle, and a button 4of nonmetallic material secured thereto, substantially as described.

3. Thecombination,withamandrelprovided with an integral shank having an oblique slot, of a clasp pivoted thereto, and a leaf-spring for actuating the clasp, secured to the mandrel by being inserted in said slot, substantially as described.

4. Thecombinatiomwithamandrelprovided with an integral shank having an oblique slot,

and ahandle in which said mandrel sinserted, my invention I affix my signature in presence of a clasp pivoted to the mandrel, and a leafof two Witnesses. spring for actuating the clasp, secured to the mandrel by being inserted at one end in said 5 slot, which slot is covered by the handle, snb- W'itnesses:
