Definitions

  • the machineless method of hair waving involves the use of a pad comprising a chemical which, when moistened, gives rise to an exothermic reaction, thus supplying the 10 heat requisite to the hair treatment.
  • the present invention more particularly, has especial relation to a new and improved means for retaining the said pad and, consequently, the accompanying chemical agent. securely in desired posil5 tion during the heating process.
  • a primary object of the present invention is to obviate the deficiencies of the prior art procedure, as hereinbefore set forth.
  • thepresent invention involves the provision of a special form of auxiliary covering for the chemical pad.
  • auxiliary covering may preferably be constructed of a pliao able metal of sufficient thickness and/or strength to hold the pad in predetermined position when in use yand to prevent its detachment or dropping oil ⁇ during the heating operation.
  • this outer shell is provided withperipherally-extending and suitably arranged reinforcing ribs and also with a flange at each end as an additional reinforcement at these points.
  • a further advantage owing from the employ- 40 ment of the new and improved heavy outer shell, according to the present invention, is that it also possesses a marked tendency to retain the heat evolved from the exothermically-reating chemical for a longer period of time than other means 46 heretofore employed.
  • Still another advantage of the device according to the present invention isl the fact that it is ready formed and can be placed over the curl with but little effort on the part of the operator.
  • Prior art devices are, as a rule, provided in flat form, and require more 'or less eiTort and time on the part of the operator'to apply them about the purl to be treated.
  • Fig. l is a perspective view of an outer covering shell constructed in accordance with the present invention.
  • Fig. 2 is a perspective .view of a chemical pad 10 member adapted to cooperate with the covering shell of Fig. 1;
  • Fig. 3 is a perspective view of a perforated inn er retaining member adapted to be associated with the covering sh'ell of. Fig. 1 and the pad of l5 Fig. 2 ⁇ to constitute a complete device, according to the invention;
  • Fig. .4 is a transverse cross section through the' asembled' device corresponding to Figs. 1, 2 and 3;
  • Fig. 5 is a plan view of a modification of the 20 invention.
  • Fig. 6 is a transverse cross section through an assembled device according to the said modification.
  • reference numeral Ill designates the 30 u outer covering shell of the device according to this invention.
  • Covering shell l0 may be made of any suitablemetal, but use is preferably made of commercially pure aluminum, this metal having been' found to possess the desired qualities 35 according to the invention, whereby it is readily. manipulable although employed in sufficient thickness to obtain the necessary strength and heat-retaining qualities.
  • Covering shell I0 as shown in Figs. l and 6 of 40 the drawing, .is preferably arcuate in form. a convenient embodiment being substantially semicylindrical. Extending peripherally about shell I0 may be a plurality of sets 'of reinforcing ribs Il. A preferred method of conguring and positioning these ribs is illustrated in Fig. 1.v Shell lll is preferably further formed at each end with an inwardly extending flange I2 which also functions to reinforce the shell and further serves as an auxiliary retaining means, as hereinafter de- '50 scribed. The free longitudinal edges of covering shell i0 are provided with inwardly and outwardly bendable extensions I3 which, as will hereinafter appear, alsohave a retaining function. Il
