14 Claims.

My invention relates broadly to hair waving apparatus and more particularly to an improved construction of hair waving apparatus designed to increase safety and efiiciency in the performance of hair waving operations in a manner more convenient both to the operator and the patron.

One of the objects of my invention is to provide a construction of hair waving apparatus in which hair may be passed into the heat treatment chamber of the hair waving apparatus without the necessity of threading 'the hair through an aperture adjacent the base of the heater chamber thereby relieving the tendency of breakage to the hair and avoiding an inconvenient operation to the patron. 7

Another object of my invention is to provide a construction of hair waving apparatus having a base portion including a radial slot through which bunched strands of the hair for treatment within the heat treatment chamber forming part of the hair Waving apparatus are passed.

Still another object of my invention is to provide a construction of hair receiving base for the heat treatment chamber where the base is divided into a pair of angularly movable sections each having radial slots therein adapted to be aligned for receiving the strands of hair and adapted to be shifted angularly for locking the strands of hair in position within the heat treatment chamber.

A further object of my invention is to provide a construction of radially slotted sectional base members adapted to close the bottom of a hair curling heater chamber where the sectional base members are so shaped and aligned one with respect to another that leakage oicondensation through the base is prevented.

A still further object of my invention is to provide a construction of mandrel adapted to 'receive the hair in wrapped formation thereon and having means for tightening the hair on the mandrel by twisting operations imparted to the mandrel after the hair has been wrapped thereon.

Another object'of my invention is to provide an arrangement of mandrel for facilitating the curling of hair within a heater chamber where the mandrel may be revolved in the direction of wrap of the hair about the mandrel for tightening the hair on the mandrel preparatory to a heat treatment operation within the heat treatment chamber.

Other and further objects of my invention reside in the provision of a closer device for the base of a heater member and an arrangement of mandrel supported thereby as set forth more fully in the specification hereinafter following by reference to the accompanying drawings, wherein:

Figure 1 is a side elevation of a heater chamber showing the construction of the base member of my invention; Fig. 2 is an enlarged elevational view of the hair waving apparatus shown in Fig. 1 with parts broken away and illustrated in cross-section to show the construction of base member and mandrel constituting my invention; Fig. 3 is a top plan view of the base of the heater chamber constructed in accordance with my invention and showing the mandrel in cross-section with the radial slots in the sections of the base aligned to receive strands of hair for facilitating the hair treatment operation; Fig. 4 is a plan view of the base shown in Fig. 3 with the sections of the base angularly shifted for locking the strands of hair in position for the heat treatment operation; Fig. 5 is a crosssectional view taken through the base on line 55 of Fig. 3; Fig. 6 is a cross-sectional View. taken through the base on line 6--6 of Fig. 4; Fig. '7 isa cross-sectional view through the sections of the base with the radial slots therein aligned to receive strands of hair, the view being taken on line 77 of Fig. 3; Fig. 8 is a side elevational view of the base with the radial slots aligned for receiving strands of hair through one side of the base; Fig. 9 is a side elevation of the upper section of the base detached from the lower section of the base; Fig. 10 is a plan view of the lower section of the base; Fig. 11 is a plan view of the upper section of the base with the metallic parts removed therefrom; and Fig. 12 is an enlarged view of the mandrel of my invention shown partially in cross-section and partially in side elevation.

I have found during the process of waving hair that the necessity of threading the strands of hair through an aperture in the base of the heater is an inconvenient operation and is undesirable both to the operator and to the patron. The threading of the hair through the aperture in the base of the heater chamber subjects the strands of hair to tension and ultimate breakage. The construction of heater of my present invention is such that it is unnecesary to thread the strands of hair through a small aperture in the base of the heater for I provide radial slots in each of, the sections of the base. These slots may be aligned by angularly shifting the sections of the base and the strands of hair passed through the aligned slots and into an enlarged aperture. The

sections of the base may then be angularly shifted for clamping the strands of hair in the aperture through the base, thus protecting the strands of hair against breakage. The sections of the base are molded with the parts thereof so interrelated as to prevent leakage from the heat treatment chamber through the radial slots in the sections of the base. The mandrel which I employ for curling the hair within the heater chamber is novel in construction in that a cylindrical member is arranged to receive the strands of hair in accordance with the operation of aheat insulated winder and thereafter the cylindrical member is adapted to be twisted-for tightening the strands of hair on the mandrel.

Referring to the drawings in detail, reference characters 1 and 2 designate a two part casing for a heat treatment chamber, the parts of the casing being interconnected along a central zone represented at 3. 2 of the casing is provided with an annular groove 4 with an end portion 5 connectedthereto, the end portion 5 having walls substantially frustovconical in shape. The shape of the end portion 5 is such that the end portion 5 fits into a recess in the sectional base portion 22. The base portion 22 constitutes an upper section as shown more clearly in Fig. 11 and is arranged to cooperate with the lower section 24 shown more clearly in Fig. 10. The upper section 22 has a diametrically extending depression 27 therein adapted to receive the diametrically extending resilient strip member 23. The strip member 23 has upwardly projecting spring fingers 23a. thereon each adapted to grip opposite sides of the groove 4 adjacent the base of the heater chamber for detachably securing the closure to the end of the heater chamber. The angularly shiftable section 24 is connected to the base section 22 and .to the end 16 of the axially extending mandrel as shown by means of the headed screw 21. Both of the base sections are centrally apertured as indicated at 21a for the passage of the headed screw device 21, suiiicient play being left between the lower section 24 and the upper section 22 as to permit of angular movement of the sections 22 and 24 relative to each other. The lower section 24 has an arcuate shaped aperture 240. therein which terminates at one end in an upward projection 24c, which projection is arranged to enter the arcuate shaped aperture 22a in the upper section 22. The upper base section 22 and the lower base section 24 each have radially extending slots 22b and 24b therein which slots may be aligned as shown in Fig. 3 for receiving strands of hair which are passed into the apertured portions 22a and 24a. The upper base portion 22 has a downwardly depending lug 22e molded integrally therewith in a position adjacent the end of the arcuate shaped aperture 22a. The abutment of lugs 24c and 22e with the extremities of the arcuate shaped slots 22a and 24a respectively serve to limit the angular movement of the base sections 22 and 24. In order to provide for the angular shifting of the sections of the base I provide integrally molded projecting arms 22d and 24d on the sections of the base which may be gripped by the fingers of the operator in effecting an angular movement of the parts of the base in clamping the strands of hair in position as shown in Fig. 4 at 30. In order to insure against the leakage of condensate from the heat treatment chamber upon a patron the base sections 22 and 24 are arranged in cooperative relation. That is, the upper base section 22 iscut The lower portion of section' away through substantially one-half the periphery thereof as shown at 220. A cooperating shell portion 240 projects upwardly from the angularly shiftable base 24 and into the cut away portion 220 of the upper base section 22. The curved shell or wall portion 240 extends approximately one-fourth of the periphery of the circular section 24 and therefore occupies approximately onehalf the length of the cut away portion 220.

By moving the finger grip 24d in a counterclockwise direction as indicated in Fig. 4 the shell or circular wall 240 is moved to a position closing the'radial slot 221) as represented in Fig. 4.

-In this way the base of the heat treatment chamber is closed and leakage prevented. The slot 241) in the position shown in Fig. 4 is closed by the solid portion of the base 22 as indicated in dotted lines. The base member 24 is faced by means of a laterally extending protective pad 28 which is secured to the lower surface of the heat insulation plate member 25. The, heat insulation plate member 25 has a plurality of upwardly extending lugs 29 through which rivet members 26 extend from the upper surface of the angularly ,shiftable base section 24 to the lower surface of the heat insulation plate member 25. An air gap is provided between the heat insulation plate member 25 and the lower surface of the angularly shiftable base member 24. The heat insulation plate member 25 and the protective pad 28, which is permanently attached thereto, are both provided with aligned arcuate shaped apertures 25a and 28a. respectively which apertures are disposed directly beneath the aperture 24a in the base member 24. A radial slot 25b is provided in the heat insulation plate member 25 and a correspondingly aligned radial slot 281) is provided in protective pad 28 both of which are directly aligned with the radial slot 241) in the lower base section 24. It will therefore be seen that lower base section 24 carries the heat insulation plate member 25 and protective pad 28, the radial slots and arcuate shaped apertures of which are all in fixed alignment. These slots and apertures may be brought into alignment with the correspondingly arranged slot 22?) and aperture 22a in the upper base section 22 as illustrated in Figs. 3 and '7. In this position strands of hair are slipped into the end closure member in a position adjacent the vertically extending mandrel preparatory to the wrapping of the hair on the mandrel under control of the winder 31 as shown in Fig. 2. The strands of hair are then looked in position through the base members by the operation indicated in Fig. 4 and thereafter the strands of hair are wrapped on the cylindrical member 15 constituting part of the mandrel which extends vertically through the heat treatment chamber by twisting winder 31. upon the cylinder 15 constituting a portion of the mandrel a protective wrapping 32' may be wound thereover to insure against scorching the hair.

Fig. 12 illustrates in more detail the construction of the mandrel. The mandrel includes the cylindrical portion 15 supported on the shoulder 16a. of the cylindrical member 16. The cylindrical member 16 has a central annular groove 16b therein through which the diametrically extending member 20 projects. The member 29 is in the form of a ratchet-having oppositely directed teeth adapted to engage the interior walls of the tubular member 15. The knurled head 17 has a shoulder 17a thereon which supports the tubular When the hair is wrapped end 19 of the cylindrical member 16 and is screw threaded in its extremity at 1811 for engaging internal screw threads on the knurled head 1'7. When theknurled head 17 is screwed to the position shown in Fig. '12, thecylindrical member 15 has sufficient freedom of movement for allowing the cylindrical member 15 to be twisted in a clockwise direction Whilepreventing movement of cylindrical member 15 in a counterclockwise direction under control of the ratchet device 20. That is to say, the ratchet device 20 grips the interior walls of cylindrical member 15 preventing counterclockwise movement of the cylindrical member 15 while cylindrical member 15 is free to revolve clockwise under a twisting action imparted to the cylindrical member 15. By reason of this construction. the hair may be wrapped on the mandrel by operation. of the winder 31. Then in order. to tighten the hair on the mandrelthe tubular or cylindrical member 15 may be given a slight clockwise twist for correspondingly tightening the hair on the mandrel preparatory to a heat treatment operation.

It will be observed in Fig. 2 that the cylindrical or tubular member 15 projects sufliciently beyond the end of the heat treatment chamber at 14 to allow twisting of the tubular member 15 from the exterior of, the casing. I have indicated the heater winding within the heater chamber by reference character 8 constituted by a winding disposed along a cylindrical shell 6 having an external shell 9 thereover. End members 7 serve to support the turns constituting the heater winding 8 with respect to the interior of the heater chamber. The ends of the conductor constituting heater winding 8 terminate in connectors which are disposed within the projecting block members 10. A lug 12 projects from one side of easing 1 adjacent the top thereof and serves to support the flexible conductor 11 while relieving mechanical strain thereon when the heater chamber is suspended with respect to a plurality of adjacent heater chambers.

I have found the construction of heater chamber made in accordance with the construction of my invention extremely practical and successful in operation, and while I have described my invention inone of its preferred embodiments, I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.
