PATENT oFFicE- HAIR CURLEB.

Application med August 18, 1927. Serial No. 213,904..

This invention relates to improvements in hair curlers of a. well known type used in permanently waving human hair. Such wavers or curlers commonly embody an electrically heated outer tube, a curling tube around which the hair is wound. said curling. tube being receivable in the heating tube, and means, for holding the two tubes in telescoped relation. The conventional holding means however is not as etiicient as it should be and, it does not in all instances serve to hold thecurling tube so centered as to prevent contact of the hair with the heat ing tube. Hence. it is the object of my invention to providenew and improved cer-s tering and holding means for the curling tube.

lVith the foregoing and minor objects in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a. perspective view of a hair curler improved in, accordance with my invention, the curling tube being withdrawn from the heating tube. v v

Fig. 2-is a longitudinal section partly in elevation, the-parts being related as shown in Fig. 1. I

Fig. 3 is a sectional view showing the heating and curling tubes telescoped with each other. i

Fig. l is a horizontal sectional yiew on line. l-4 of Fig. 2 showing more particularly the construction of the sleeve which is instrumental in anchoring the centering andholding device for the curling tube.

Fig. 5 is a perspective view of the sleeve just referred to and a portion of the renresingand holding device.

Fig. 6 is a side elevation partly broken away and insection, showing the manner in which comparatively large curling tubes may beinternally hushed tor coaction with the centering and holding device.

Int'hedrawing above briefly described, the preferred form of construction has been illustrated and While this construction may be followed if desired, it is to be understood that within the scope of the invention as claimed, numerous variations may be made.

The numeral 7 designates the heating tube having the usual electric heatirugmeane 8 and handle t), and 10 denotes'the curling tube which is insertible into. said heating DONART, or VAN tube as shown in Fig. 3, the lower end or this curling tube being provided with theconventional means 11 for engagement with the hair near the scalp, said means 11 commonly embodying a ratchet which permits tightening of the hair after it has been wrapped about the tube- Mounted centrally within the heating tube 7, is a centering and holding device 12 for the curling tube 10, said device being receivable within said tube 10 when the tubes 7 and 10 are telescoped as in Fig. 3. Thus the device 12 effectively holds the tube 10 centered within the tube and prevents contact of the hair with said tube .7, overcoming danger of burning such hair. Moreover, the device 12 etl'ectively holds the curlingtube 10 against accidental dropping from the heating tube 7. Attention is further invited to the. fact that as the device 4 12 engages the inner side of the tube 10 rather than its outer side, there is no danger of saiddevice contacting with thehair and ,th us producing undesirable formations upon the latter incident to the waving operation.

The device 12 is expansible and contractable to t'rietionally contact with the tube 10 and in the preferred form of construction, said device embodies two lengths of spring wire whose upper and lower portionsmay be rather tightly twisted together as at 13 and 14, while the intermediate portions of the wire are outwardly bowed at intervals, asv denoted at 15, thus providing yieldable means to trictionally contact with the tube 10.

The wire structure so far described, forms a portionof a longitudinal shaft disposed in he 'h ating'tube 7' for holding and iering the curling tube 10. The remainder of this shaft may well be formed by a tube 16 secured around the wire ends 14, and a ill 'the tube 7 as shown in Figs. 1 and 2','but as second tube 17 slidably surrounding the tube 16. Tube 17 forms the lower end of the shaft and it normally is so positioned at the lower end 'of the tube 7, as to be clearly visible, thus making it an easy matter to 7 guide the shaft into the tube 10. Preferably, the tube 17 protrudes somewhat from it would interfere with complete sliding of the tube 10 into tube 7, if permitted to re-.

main in this projected position, said tube 17 has been slidably mounted upon the tube 16. Thus when this tube 17 contacts with the upper end of the'means 11 as shown in befiared as at 20 if desired. Moreover, the

lower'end of the shaft may be given a substantially conical form as at 21 to assist in the guiding operation. Either of these formations 20-21 might be successfully used but preferably both are employed.

As customary, the tubes'lO are of different diameters, and if desired, relatively large tubes such as that shown in Fig. 6, may be provided with an internal lining or bushing 22 to insure tight frictional confact with the tube centering and holding device or shaft. 7

Any desired means mayof course be employed for mounting the centering and holding device or shaft in the tube 7. In the 7 suitable.material, fillstheupper portion of sleeve 23. preventing undesirable radiation of heat which would otherwise take place;

By employing the novel construction herein shown and described or any analogous construction falling within the scope of the invention-as claimed, a hair curler or waver is produced. which wlll be greatly advan tageous over the conventional devices heretofore employed, particular attention being -invited tothe facts that the tube 10 is effect-ively held centered in the tube7, said tube 10 is tightly held against accidental dropping from the tube 7, and the centering and holding means for said tube 10 does not contact with the outer side of the latter and hence can by no possibility come in contact with the hair being curled or waved.

I claim: i

1. In a hair curler embodying a heating tube and a curling tube insertible into said heating tube; a centering device for said curling tube mounted centrally in said heating tube and insertible into said curling tube when the two tubes are telescoped.

2. Ina hair curler embodying a heating tube and a curling tube insertlbl'e into said heating tube; a-n-flexpansible and contractable centering device for said curling tube mounted centrally in said heating tube and insertible into said curling tube when the two tubes are telescoped, said device being adapted to contact with the inner side of the curling tube to retain the two tubes in assembled relation. j

3. In a hair curler embodying a heating tube and a curling tube insertible into said heating tube; a centering shaft for said curling tube mounted centrally and longitudinallyin said heating't-ube, said shaft being receivable in said curling tube when the two tubes are t-elescoped.

at. A structure as specified in claim 3; said shaft having a yieldableportion to frictionally contact with the inner side of the curling tube to retain the latter in the heating tube. a 5. A structure as specified in claim 3; said shaft being expansible andcontractable to contact with the inner side of the curling tube to retain the latter in the heating tube.

6. In ahair curler embodying a heating tube and a curling tube insertible into said heating tube a centering shaft for said curltube mounted centrally and longitudinally'in said heating tube, and having one end portion exposed to view at the .end of said heating tube which initially receives said -urling tube, said shaft being receivable in said curling tube when the two tubes'are telescoped. p 7. A structure as specified in claim 6; said end portion of said shaft being slidably connect-ed with the body portion of the latter for the purpose set forth. v

8. A hair curlercomprising a heating tube, a curling tube insertible: into said heating tube, and a centering device for said curling tube mounted in said heating tube, said curling tube being provided with a flared end for guiding said centering device into said curling tube when the two tubes are telescoped.

9. A hair" curler comprising a heating tube, a curling tube insertible into said heating tube, and a centering device for said curling tube mounted in said heating tube and rcceirable in said curling tube when the two tubes are telescoped, said centering device having a substantially conical end for guiding; it into said curling tube.

10. In a hair curler embodying a heating tube; a sleeve mounted stationarily in said tube and having opposed inwardly stamped side portions, a pin extending between and it through said side portions, and a centering device for a curling tube, said centering device being connected to said pin.
