In Canada October 6, 1941 1 Claim.

The invention relates to improvements in hair curling pads, as described in the present specification and illustrated in the accompanying drawing that form a part of the same.

The invention consists essentially of the novel features of construction as pointed out in the claim for novelty, following an explanation in detail of an acceptable form of the invention.

The objects of the invention are to reduce the cost in the manufacture of pads utilized in hair curling by avoiding the use of expensive covers such as aluminium or tinfoil, and substituting (Cl. 132-362) V there in place a cover less expensive and more efficient for the purpose and permitting the use of the aluminium or tin, thus saved, for more important manufactured products; to enable hairdressers and others to accomplish a better permanent hair wave than heretoforadue to the fact that the pads may be applied to the hair for a longer period than the ordinary pads using metal foils; to allow the hair to remain moist and soft after the use of the non-metallic pads and minimizing the danger of burning of thehair which occasionally occurs through the use of metallic pads, and also preventing the hair from being dried and brittled and the consequent ruination of the same, which is often the penalty for those persons who-have too many permanent waves applied to the hair, and through the use of a non-metallic pad it is immaterial how many permanents a person may have, in fact, the more permanents the better, it is for the hair; and, generally, to provide a non-metallic hair curling pad that will be comparatively cheap to manufacture and eflicient for its purpose. 1

In the drawing:

Figure 1 is a perspective view of a non-metallic hair curling pad. 1

Figure 2 is an end view of the pad.

Figure 3 is a plan view of the cover in its extended position prior to its attachment to the pad.

Figure 4 is a plan view of a modified form of cover.

Like numerals of reference indicate corresponding parts in the various figures.

Referring to the drawing, the non-metallic hair curling pads consist of one or more sheets of absorbent material such as flannelette, as indicated by the numeral Ill, and a sheet of wax paper sewing or other fastening means [4 and, thereby, completing the pad.

The non-metallic cover is formed of an elongated sheet of paper l5, which is treated by a chemical process to make the paper heat-resisting and this paper is preferably treated with a wax sulphite or other standard heat resisting paper procurable on the market. This sheet of paper is simply folded doubly and has its free ends 5 sewn together and to the wax paper and the flannelette sheets, and an additional sheet I! of heat-resisting paper is insertedbetween the folds of the elongated sheet of paper and secured thereto.

In Figure 4 the non-metallic cover is formed of an elongated sheet l8 having the folding lines l9 and 20 so that by bending this sheet of paper (which is also chemically treated for heat-resisting) over the folds a triple sheet will be formed and one edge of the triple sheetis secured to the wax paper and the absorbent material sheets to complete the pad.

The application of the pad to the hair is accomplished in the same manner as those pads having metallic covers, that is to say, the hair is first treated with a suitable solution which is specially prepared for the curling of the hair; the flannelette sheets are dipped into water or other liquid, and the pad is then applied by folding over the rolled portion of the hair and held thereto by means of a clamp which is heated, and the heat derived from the clamp will be transferred through the non-metallic covering to the wax paper and the flannelette sheets and into the hair and, by the use of a non-metallic covering,

the heat is conserved for a longer period than would otherwise be the case if it were applied to a metallic covering, and consequently, the hair will not be subjected to a sudden inrush of heat radiation but to a gradual radiation of heat and,

In using the non-metallic pad, the solution isgradually heated and exudes a gradual chemical reaction to the hair for forming the curl and,

since the heat is not too great, the natural oils which are'so important to the hair are allowed to remain, with the result that excellent curls are gether, and an intermediary heat resisting chemically treated sheet located between the folds of said cover and having one end secured to the fastening portion of aid pad.
