CURLING-IRON.

SPECIFICATION forming part of Letters Patent'No. 429,279, dated June 3, 1890.

- Application filed April16, 1889. Serial No. 307,493. (No model.)

To aZZ whom, it may concern.-

Be it known that I, FREDERICK D. MILLER, 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 a novel construction of curling-iron of the kind wherein a cylindric metal mandrel is provided with a handle at one end, and which is used by heating the mandrel and curling the hair about the same.

This invention embraces a novel construction of handle whereby the transmission of heat from the mandrel to the handle is materially decreased, and also embraces a novel construction and arrangementpf the springclasp and its spring; and it consists in the novel features of construction and combinations of parts hereinafterfully described, and pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a curling-iron embodying my invention. Fig. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is an enlarged vertical transverse sectional view 011 the line 3 3 of Fig. 2. Figs. 4., 5, and 6 are views of a modified form of construction embodying my invention. Fig.7 is a plan view of a portion of my invention, and illustrat ing the hinge of the spring-clasp and its spring.

In said drawings, A is a mandrel, which is hollow and of cylindric form.

B is a hollow handle of cylindric form and corrugated longitudinally. The handle B is open at both ends, and the mandrel A is inserted and secured in one end thereof. It will be noted that a plurality of small openings b b are thus provided between the adjacent ends of the mandrel and the handle by reason of the irregular contour of the handle.

C is a spring-clasp arranged upon the mandrel, and is provided at its rear with an out- Wardly deflected portion 0, having a fingerbutton 0, which forms an operating-handle for said clasp. The clasp C is held by means of a depression a, formed in the mandrel A, into which a lug or projection c on the springclasp is adapted to enter.

D is a wire spring comprising a cross-piece d and downwardly-deflected arms d d. The cross-piece d rests in a slot 0 in the springclasp forward of its pivotal point, and the arms (1 d pass downwardly on either side of the mandrel and have their ends secured in two of the openings 1) b.

E is a heating-iron provided at one end with a connecting-piece e and a thumb-piece e. The said thumb-piece is provided with a hub 6 having an annular groove c and a cut-away portion 2 Upon the rear end of the handle B an inwardly-projecting lug b is formed. It is obvious that the iron E can be passed through the handle from the rear and introducedinto the mandrel. The operator then brings the cut-away portion 6 opposite the lug b and pushes the hub e in until the groove e is in line with said lug. By giving the thumbpiece 6 a turn the said lug b will be caused to enter the annular groove 6 and thus hold or lock the iron against displacement.

The object in corrugating the handle, as will be readily understood, is to prevent the said handle from becoming too highly heated, the openings 1') formed between the corrugations in the handle and mandrel allowing a free circulation of the air within the same for the above purpose. The said corrugations also provide a convenient handle that can be firmly grasped when using the device. It will be manifest that the corrugations can be made otherwise than straight-as, for instance, ihey could be arranged spirally and still serve the ends of this invention.

In Figs. 4, 5, and G I have illustrated modified forms of devices embodying my invention by which the heating-iron is held within the mandrel. In Fig. 4c the hub c is made large enough to fit tightly within the end of the handle and be held in place by friction. In the device illustrated in Fig. 5 the connecting-piece 6 between the hub and the iron is curved sufficiently to engage the insides of the handle, and thus hold the said iron in place by the friction between. said connecting-piece and the handle. In Fig. (i the hub c is held in frictional contact, as shown in Fig. 4, but the thumb-piece e is reduced to the same or smaller diameter than the hub e This is a very desirable construction, as spaces 1), similar to the spaces 1), are opened at this end of the handle B, and thereby permit the free passage of a current of air directly therethrough.

I claim as my invention- 1. A curling-iron comprising a mandrel and a hollow corrugated handle, substantially as described.

2. A curling-iron comprisingamandrel and ahollow corrugated handle, said mandrel secured at one end within the end of the said handle, substantially as described.

3. A curling-iron comprising a hollow mandrel secured at one end within the end of a hollow corrugated handle, and a heating'iron adapted to be introduced into the mandrel from the rear through said corrugated handle, said iron being provided on its rear end with an engaging device to hold it in place, substantially as described.

l. The combination, with a curling-iron comprising acorrugated handle, a mandrel secured at one end within said corrugated handle, and a heating-iron, of a clasp arranged upon and pivoted to said mandrel, said clasp being provided with alug adapted to enter a depression in said mandrel, and a spring secured to said clasp and having arms which are arranged on eitherside of the said mandrel and are secured within openings formed between. the corrugations in said handle and the end of the mandrel, substantially as described.

In testimony that I claim the foregoing as my invention I afiix my signature in presence of two witnesses.

FREDERICK l). MILLER.
