HEATER FOR WAVING HAIR Original Filed July 11. 1923 lNVENT Chdrles 6. M25535 N12 ATTORNEY Reissued Dec. 24, 1929 UNITED STATES PATENT OFFICE GHAELES G. NESSLER, OF NEW YORK, N. Y., ASSIGNOR TO THE NESTLE-LE MUR COM- PANY, OF NEW YORK, N. Y., A CORPORATION OF OHIO HEATER FOR WAVING HAIR Original No. 1,595,808, dated August 10, 1926, Serial No. 650,784, filed July 11, 1928. Application for reissue filed August 4, 1928. Serial No. 297,448.

My invention relates to heating devices which are adapted for use in the art of waving hair, and the improvements are especially applicable to heaters which are now used so extensively in the process of waving natural hair on the head of the subject, and which derive their heat from an electric current. In using these heaters, the hair in strand form is wetted and then wound around a rod in helical turns and is then covered or not with absorbent material and inserted within the bore of the electric-heater, after which the current is applied for several minutes and until the heat is run up to quite high degree, generally to the boiling point. Under this condition the heater body becomes too hot to be grasped directly in the hand of the operator who has to manipulate the heater and remove it. In this process, the head-end of the heater is usually provided with a closure for aiding the process and also for keeping the vapors and heat away from the scalp of the subject and heat insulating or protecting means are often used. My present invention provides hand grasping means or handles for the heater which are kept from becoming highly heated; also means for detachably ap plying a closure to the head-end of the heater,

as well as means for protecting the head or scalp of the subject from the heated end of,

the body of the heater. Other provisions are also made by my present improvements which will appear in the description hereinafter ven.

I have illustrated an embodiment of my in-' Fig. 3, 1s a similar view to that shown in- Fig. 1, with the resilient handles or grasps pushed inwardly towards the shell to release the gripping jaws from the closure, the latter being removed.

Fig. 4, is a cross-sectional view of the device, the plane of the section being indicated by lines 44, in Fig. 1.

Fig. 5, is an end view of the closure shown as detached.

Fig. 6, is a cross-sectional view of the device, showing a modified form of the retain ing band and sliding connection between the same and the resilient handle members.

Referring to the drawings, 1 indicates a tube open at both ends and rovided near the, head-end with a surroun ing casing 2, within which is arranged the usual electric heating coils which need not be here illustrated, the said parts 1 and 2 being secured together. This structure is the ordinary one used so generally in the process of permanent waving of natural hair on the head of the subject, an electric wire being connected with the structure to furnish the heating current and the structure being suspended overhead by suitable means not shown, groups of two or three dozen being so arranged as often that number are used for waving the hair of the subject.

For this structure, I provide a simple and efficient hand-grasping means which retains comparatively little of the heat of theattached body part or shell, said means at the same time serving as clamping means for the closure which I apply to the head-end of the outwardly from the shell as at 8, and near the head-end they are bent sharply inwardly as at 9, for the reception of a loose retaining band or ring 10, which surrounds the arms and keeps them close to the exterior of the shell, at the same time to permit of the arms having an endwise movement with respect to the shell, when the arms are pressed inwardly towards the same, the band 10, at such time moving with the arms, as indicated in Fig. 3. v

The free ends 11, of the arms 6 and 7 which lie at the head-end of the body member of the heater, form clamping jaws for engaging and clamping the inwardly extending projections 13 and 14, on the closure 15, which is detachably mounted upon said end of the devlce. The extreme ends of the spring-arms or bars 6 and 7 are rolled inwardly, as at 12, so as to form rib-like parts which engage the bends or indentations 16, respectively, in the projections 13 and 14, of the removable closure 15.

The closure 15, comprises a pair of members or plates 17 and 18, which are shaped as shown in plan in Fig. 5, and are pivoted together at 19, the member 17, having a handle 20 and the member 18, having a handle 21, so that they together form somewhat of an X- shaped'structure. The opposing edges of the members 17 and 18, are formed with correspondii'ig'notches 22 and 23, which when the members are closed provide an opening 24, for the reception of the curler rod 25, and the wound. hair 26, as indicated in Figs. 1, 4 and 6. The outer ends of the two closure members are kept together when closed, by means of the end ofblade 18, takin into a groove formed by the bent-over ear 2?, on the end of blade 17 and this arrangement serves to maintain the adjacent faces of said plates in close contact, as shown in Figs '2 and 5. A spring 28, carried by the pivot 19, of the blades, has its respective ends in engagement with the finger pieces or lugs 29 and 30, on the ends of the respective handles 20 and 21, of the closure plates 17 and 18. This spring acts to normall keep the handles apart and the plates close as shown in Fig. 5, and when the two handles are pressed together by the fingers of the operator, the closure plates are 0 ened so that they may then be placed over t 1e head-end of 4 the heater shell, whereupon the release of said handles causes the spring to come into play and clamp the said lates 17 and 18, against the exterior of said min The closure is also clamped in suspended position against the end of the shell or body part, by means of the jaws ll, 11, on the free ends of the arms 6 and 7, said jaws engaging the outside of the inwardly projecting pieces 13 and 14 of the closure, as hereinabove described. The bars 6 and 7, being formed of resilient material and being held near the said jaws by the retaining band 10, exert a spring clamping action on said jaws which is imparted to the projections engaged thereby.

The head-end of the heating shell is provided with a protecting-cap 31, made of felt or suitable fibrous material and fitted snugl over the end of said shell so as to extend we 1 down on the exterior thereof and also to cover the end of the same, the closed end of said cap being formed with an orifice 32, for permitting the curler rod with the wound hair thereon to extend through the cap into theinterior of the shell. This substantially large felt cap serves to protect the head of the subject from the heated end of the shell and to that extent increases the comfort accompanying the use of the device.

In Fig. 6, I show a modified form of the retaining band or ring which on ages the exterior of the resilient bars 6, and and which in the first form is shown as oval shaped at 10, in Fig. 4. In the modification, the band is circular in plan as at 10, and at opposite points is provided with recesses or hands 33 and 34, for the reception of the respective bars 6 and 7, which slide therethrough.

In using the device, the strand of hair 26, being wound on rod 25, and tied thereto in the usual wayand the hair wetted and, if preferred, wrapped in wetted absorbent material, then placed in a steaming-tube and this assemblage is inserted in the interior of the heating shell, the side handles 6 and 7, of which are grasped in the hand of the operator and pressed together so as to open the jaws 11,

11, whereupon the closure'is applied by pressing together its handles and opening its plates so as to pass them around the wound strand of hair and place the inner face of the same in contact with the felt covered end of the shell. 'When the closure is thus seated in place, the resilient bars 6 and 7, are released and the jaws thereof close against the projections on the closure plates and hold them as shown in Figs. 1 and 2. The electric current is then applied and the process carried out as above stated.

The combined hand-grasps and clamping means in the form of the resilient strips, provide a surrounding cage-like structure, w ich is kept comparatively cool because the heat from the heater cannot well be conveyed to it and in addition to having the lateral movement relatively to the body of the heater when grasped and squeezed, it also has an endwise creeping movement on said body.
