4 Claims.

This invention relates to hair waving appliances and more particularly to the pads used in the chamber of the heaters of permanent waving machines.

In the permanent waving of hair pads of moisture absorbent material have been used in the heaters in which the wound hair is treated for the purpose of absorbing the moisture of condensation which otherwise might be so excessive as to leak from the heaters upon the scalp of the person being treated.

Although sanitary reasons make it inadvisable to use the pads for treating the hair of more than one person, nevertheless it frequently occurs, because of economy and other reasons, that the wet pads are removed from the heaters, dried, and then reused.

An object of the invention is to provide a pad to be used with the heaters of permanent waving machines which can be used for only one treatment, since its removal from the heater for the purpose of drying the same, acts to destroy it and render it unfit for further use, thus assuring sanitary conditions.

Further and additional objects and advantages will appear hereinafter during the detailed description of an embodiment of the invention which is illustrated in the accompanying drawing wherein,

Fig. 1 is an elevational view of one type of heater for a permanent waving machine and with which the pad may be employed.

Fig. 2 is a sectional view taken substantially on line 2-2 of Fig. 1 looking in the direction of the arrows.

Fig. 3 is an elevational View of the heater with the parts thereof in open position.

Fig. 4 is a detail plan View of the pad, and

Fig. 5 is a sectional view through the pad taken substantially on line 5-5 of Fig. 4 looking in the direction of the arrows.

The moisture absorbent pads embodying the present invention may be used with various types of heaters for permanent waving machines as, for example, steam, electric or chemical heaters. However, in order to conveniently illustrate the manner in which the pads are used the present illustration discloses a pad embodying the invention employed in a heater of the steam type, such as is shown in the Murray et a1 Patent No. 1,974,625, issued September 25, 1934.

Briefly, the heater illustrated herein comprises a rotatable rod l0, upon which the hair to be waved is wound and which rod is adapted to be located in the housing of the heater. The hous- 1935, Serial No. 30,662

ing is'of generally rectangular cross-section and is formed of two substantially U-shaped half sections it and i2, pivotally connected together so that they may be opened to receive the rod and then closed upon the rod. The half sections ii and l2 of the housing are securely clamped and locked together by suitable means, such as the spaced links I3 pivotally connected to one of the half sections and adapted to receive between them a tongue it projecting from the other sec tion. The free ends of the spaced links 13 have pivotally mounted therebetween a cam or eccentric shaped locking member !5 provided with an extended operating handle 16. The sections H and i2 on one side thereof are provided with heat insulating blocks H and with hair clamping blocks i8 preferably formed of rubber. The half section i2 of the housing is provided intermediate its length and in one edge thereof with an 0pening in which is arranged a swiveled fitting l9, whereby a steam conduit 2!] can be connected to the heater in communication therewith. Inasmuch as the construction of the heater illustrated herein and the mode of its operation is fully set forth in said Murray and Lewis Patent No. 1,974,625 and is well understood in the art, a more detailed description thereof is unnecessary.

As previously stated, it is preferable to employ in the heaters of permanent waving machines pads of moisture absorbing material, for the purpose of collecting and absorbing the moisture of condensation, so that danger of the latter leaking from the heater upon the person being treated is eliminated. These pads should only be used for one treatment, inasmuch as it would be highly unsanitary to use the pads over and over again for a number of treatments. Notwithstanding this fact it is the practice in some beauty shops and similar places to remove the pads from the heater after they have been used, dry the same, and then use the pads over again for another customer.

The present invention contemplates the provision of pads of moisture absorbent material for use in the heaters of permanent waving machines, which can only be used for one operation and which are automatically destroyed by the act of removing the pads from the heaters. The pads are indicated at 2! and in this instance are of such size and shape as to fit within the half sections, as clearly shown in Figs. 2 and 3, and are provided in one edge with a semi-circular recess 22 to accommodate the swiveled fitting l9. Each pad 2! is formed of suitable soft pliable Cir moisture absorbing material, and is built up of superimposed thin layers 23 of the material which are pressed together into adherent relationship and particularly along the longitudinally extending depressions 2Q which are formed in. the material by the compressing operation. The pad is provided with a. number of short slits 25 extending completely through the pad and forming weakened zones in the pad. As shown in Fig. 4, the pad is provided with two of the slits 25 which extend angularly across the pad adjacent to the semi-circular recess 22, but it will be understood that the number and the arrangement of the slits 25 can be varied as desired. Following a hair waving operation the pad 2| will be saturated with the moisture of condensation, and when it is attempted to remove the pad from the heater the weakened zones formed by the slits 25, in addition to'the frangible condition of the pad because it is saturated with moisture, results in the layers of the pad separating and tearing, wherefore the pad is rendered unfit to be dried and reused.

In the present embodiment the weakened zones formed by the slits 25 are adjacent to the semicircular recess- 22 which, in itself, forms a weakened zone and hence the pad is rendered more susceptible to destruction when it is removed in a moisture laden condition from the heater.

It will be noted that the slits 25 extend in a direction substantially transverse to the longitudinal length of the pad. In removing the pad from the heater the usual practice is tograsp one corner of the pad and then pull the same out of the heater lengthwise, as distinguished from grasping an edge of the pad and removing the same by exerting a transverse pulling action thereon. Since the slits extend substantially transversely to the longitudinal length of the pads, it will be seen that the weakened zones formed by the slits lie substantially transversely to the direction in which the force is normally exerted to remove the pad from the heater.

Although a preferred embodiment of the invention has been illustrated and described herein, it should be understood that the invention is susceptible of various modifications and adaptations within the scope of the appended claims.

Having thus described my invention I claim:

1. A pad for use within the hair receiving chamber of a permanent waving heater formed of moisture absorbent material and provided with slits therethrough and extending substantially transversely thereof and creating therein weakened zones arranged substantially transversely to the force normally exerted upon the pad to remove the same from the hair receiving chamber.

2. A pad for use within the hair receiving chamber of a permanent waving heater formed of superimposed layers of moisture absorbent material pressed together into adherent relationship and provided with slits therethrough and extending substantially transversely thereof and creating therein weakened zones arranged substantially transversely to the force normally exerted upon the pad to remove the same from the hair receiving chamber.

3. A permanent waving appliance comprising in combination a heater having hair clamping means and a heating chamber adapted to receive the rod upon which the hair is wound, and a 5 pad arranged in said chamber and formed of moisture absorbent material and provided with slits therethrough extending substantially trans.- versely thereof and creating therein weakened zones arranged substantially transversely to the force normally exerted upon the pad to remove the same from the chamber.

4. A permanent waving appliance comprising in combination a heater having hair clamping means and a heating chamber adapted to receive the rod upon which the hair is Wound, and a pad arranged in said chamber and formed of I superimposed layers of moisture absorbent material pressed together into adherent relationship and provided with slits therethrough extending substantially transversely thereof and creating therein weakened zones arranged substantially transversely to the force normally exerted upon the pad to remove the same from the chamber.
