contrive-IRON ATTACHMENT.

Application filed OctoberB, 1827. Serial No. 223,604.

application refers are provided with two members connected together in the manner of a. tong, one of these members is formed from a cylindrical bar ofmetal and the other from a piece of thin metal bent transversely into U-sha-pe. so as to form an elongated groove for the' reception of the other member. In using these tongs great care must be exercised by the operator so thatneither the metal bar nor the edges of the Ushaped member will come into contact withthe scalp as they are hot and will cause burns.

It is the object of this invention to produce curling devices of this kind with means that will prevent the hot parts from coming into contact with the scalp of the person whose hair is being curled thereby making it possible to employ these devices without fear of causing injury and which can therefore be brought into contact with the scalp without danger.

.It is another object of this invention to an arrangement of parts that will hereinafter he described in detail and reference for this purpose will now be had tothe accompanying drawing in which the preferred embodiment thereof has been illustrated and .in

which:

Fig.1 shows a side elevation of a curling 7 device which has been provided with my protective device; I

Fig.2 is a perspective view showing the protector that is attached'to the cylindrical heating element of the device illustrated in Fig. 1'; i i Fig. 3 is a section taken on line 3-3, Fig. 1;

Fig; 4: is a side elevation vof aportion of a curling device of the type illustrated in Fig. 1 and shows a slightly modified form of protector;

Fig. 5 is a transverse section taken on line 55, Fig. &;

F ig. 6 is a fragmentary detail showing a slightly modified form of construction;

Fig. 7 is a side elevation of the cylindrical heating element, shown in the device illustrated in Fig. 1, and shows the protector in' place thereon, the protector has been shown partly in section so as to better illustrate the construction; and l Fig.8 is a side elevation partly in section of a slightly different form of a curling device showing myprotectors applied thereto. Numeral 1 represents the cylindricalheating element of a curling device. This heating element is tubular and contains an electric resistance wire by means of which the heat is generated. This has not been shown asit is a very common construction. Secured to one end ofthe heating element is a handle 2 which is provided with a metal ferrule 3. A cooperating aw member 4, which is formed of thin metal bent transversely into the shape shown in Fig. 3, is pivotally connected at 5 to a sleeve 6 that encircles the heating element 1 and holds the member 4 in place thereon. A spring 7 is attached to the pivot 5 and is provided with an opening for the reception of the screw 8 by means of which the parts are held in assembled position. A handle portion 9 which is integral with the part 41eX-. tends rearwardly and carries a thumb piece 10 0f heat insulating material. \Vhen pressure is applied to the thumb piece, the memher 4 can be rotated about the pivot 5 so as to move it away from the heating element somewhat in the manner of a pair of tongs. It will be seen from Fig. 8 that the member 4 has its side edges extending down beyond the heating element 1 and these edges are flared outwardly. As the member 4 comes either. into direct contact wit-h or into close proximity to the heating element 1, it becomes very hot with the result that if the edgescome in contact with the scalp, they will cause burns. In order to keep the extreme edges of the member 1 from getting excessively hot I haveprovided longitudinal slots 11 which extend substantiallythe entire length of the clamping member. These slots are so long that they leaveonly a very thin section of material at points 12 and 13. I The metal portions'lo that form the outer edges of the OFFICE.

clamping member must therefore receive ali their heat by conduction through the connect ing

sections

12 and 18 and as these have very small sectional areas, only a small amount of heat will be conducted to the parts with the result that they never become very hot. It is element is always very hot. With a device of this type as usually constructed, it is'therefore essential thatthe operator shall exercisegreat care to keep the metal'pa'rts from coming into contact with the skin'of the per sonwhose hair is being curled.- In order to prevent injury from the heating element 1,1 have provided the same with a protector. 16, which is formed froma bar of insulating material, shaped somewhat-like that shown in Fig. 2. This bar has a cross section 'substantially like that shown in Fig. 3, and is provided at its outer end with a conical portion 17, which extends to one side of the fiat surface 18. This conical portionhas aconical recess 19, which is adapted to receive the point -20 of the hea-tingelement 1 in the man-' ner shown most clearly in Fig. 7. 1

For the purpose of holding this protector bar 1n place, I have provided a ring 21 that is placed around the heating element-'1 be-- tween the sleeve 6 and the ferrule 3 in the manner shown in Fig. 1. A coil spring 22 has one end secured to the end of the protector bar 16 in the manner shown in Fig.7 and has its other end provided with a hook- 23 that engages the ring 21 in the manner shown in Fig. 2. When the protect-oris applied the hook 23 is connected with the ring 21 and the spring 22 extended sufiiciently topermitthe point 29 of the heating element to be inserted into the recess 19. The tension'o't the spring 22 will then hold the protector 16 in place in the manner shown. I l

I Attention is called at thispoint to that the 'protectorlti is bowed so that the sur face 18-which lies adjacent to the heating element 1 contacts with the latter only at the ends of the bar in the manner shown in Fig. 7. From Fig. 7 it will also be seen that the recess 19 has a greater taper than the end 20 of the heating element so that the edges of the part1? will only come in contact with the heater, leaving a space between-the surface of the end 20 and the interior surface of the recess, 19 in themanner shown. This reduces the capacity for conductingheat and; serves to keep the end of the protector coolerthan itthe fact would be} if the entire surface of the recess came into contact with the heater.

In order to further decrease the transference of heat from the heater to the end 17,

I have jrovided o )enin s 24 which Jermit air to circulate through the recess and this also retards the heat transfer. The protector shown in Fig. 2 can be manufactured as an accessory and can be attached to any curling device'constructed like that shown in Fig. 1 by merely removing the clamping member 1,- inserting the heater through the ring 21 and reapplying the clamping member untilthe parts assume the position shown in Fig. 1.

The-tip 20 is t'henmerely inserted into the recess 19 and the protector will thereby be held in place.

Instead of providing the longitudinal slots 11 for the purpose of preventing the parts15 from becoming heated, it is possible to provide the outer edges with bars of poor heat conducting material such as those indicated lay-reference numeral 25,'in Figs. 4 and.5. When this construction is employed the bars 25 have their ends provided with slots 26,, which are engaged by the PIOJBCUOBS 27 that extend from-the clamping element e in the manner shown. These slots should bewdeep enough so that the metal forming the parts 27 will not come in contact with the scalp when the device is in use.

It is obvious thatthe protector: 16 can be secured to the heatingelement in many different ways and in Fig. 6 I have shownan ex ample of such a modification. In this construction the sleeve 6? which corresponds to sleeve 6 in Fig. 1 is provided with a spring tongue 28,. whose outer end'is provided with a book 29 that engages a notch 30 in the protector, 16. The other end of the protector is formed exactly like thatshown in Fig. 7 and it can be readily applied bymerely sliding the inner end underneath the tongue 28 until the parts are in the positionshown.

As above intimated many other ways of securing the bar can easily be devised and I want it understoodthat the examples shown and described are illustrative. of means for this purpose only and are not intended to be considered as in any way limiting the invention to these specific devices.

In the above parts of the specification, I

have illustrated my invention connected with one form of a curling device and in order to show its adaptability to other forms, I have shown in Fig. 8 a side elevation of a slightly different form of a curler. In this devic ethe bars 31 correspond to some extent to the heating element 1, in Fig. :1, but are merely solid metal bars which are not provided with any heating devices. The heater in this modifies tion is located in the channel 32 between the twoparts ot the clamping member 4?. Heat protectors 25 are secured to the edges of the clamping member 4: in the manner shown in Fig. 4, or the edges may be provided with slots 11 in the manner shown in Fig. 1. Protectors 16 are secured to the bars 31substantially in the manner described, but instead of the coil spring 22 and the ring 21, I have provided bent spring wire members 33, one end ct which is secured to the end of each protector bar 16 and the other end of which is inserted through a hole 34 in the bars 31. The protectors 16 serve to separate the hot bars 31 from the scalp while the device is in use, all in the manner above explained.

From the above it will be apparent that I have provided a simple means for protecting the user against injury from the heated parts of the curling device and that my inventionis so constructed that it can be readily applied to curling devices of ordinary construction.
