COOPER, ADMINISTRATOR, OF N EWARK, NEW/V JERSEY, ASSEGNOR TO THE NESTLE- 'LEMUR- COMPANY, OF NEVI YORK, N. Y., A CORPORATION OF OHIO HAIR-WAITING- MACHINE Application led January 6, 1932. Serial No. 584,984.

This invention relates to improvements in hair-waving machines and has particular reference to an apparatus employed in the process of permanent waving.

An object of the invention is to provide a simple and practical machine wherein the construction of the various instrumentalities constituting the same is such as to greatly facilitate their assembly.

Another object is to materially reduce the effect of heat radiation by including, as a part othe machine, a :tan which will direct a cooling current of air on to the heaters of the machine while the same are in operation, thereby overcoming, to a large extent, the inconveniences to which a person is subjected when the hair is being waved.

A further obj ect is to provide an improved device for supporting the cord of a heater whereby the same may be adjusted relative to the Jframe from which the heater is suspended, and frictionally held in its adjusted positions.

A still further object is to provide an eilicient and durable device for supporting the heater cord in a. manner which will prevent accidental detachment of the cord from the device and through the medium of which excess strain upon said cord, occasioned by pulling the same in certain directions, will be relieved.

Still another object is to increase the etliciency of control of the machine by assembling various control instrumentalities in one compact unit and mounting the same conveniently within reach of the operator.

The above and other objects will appear more clearly from the following detailed description, when taken in connection with the accompanying drawings, which illustrate a preferred embodiment of the inventive idea.

Figure 16 is a plan view of the other of the sections of the plug, illustrating the arrangement of grooves and recesses therein.

In its preferred form, the invention is shown as comprising a standard 20 having 'an upper angular section 21 forming an eX- tension by means of which the height of the standard may be varied, a set screw 22 or any other means being employed to secure the section 21 in its adjusted positions. Adjacent the upper free end of the section 21, the same is provided in its under surface with an opening 23 and contiguous to this opening there is secured to said section, by means of rivets 24, a casting 25. This casting forms 'a part of a head utilized to support various elements of the machine and said head further includes a shell or casing 26, preferably-ofl cylindrical formation, which is detachably secured to the casting 25 by means of screw bolts 27 inserted `into the shell upwardly from the bottom thereof so that, when the detachable bottom plate 28 of said shell is removed, ready access may be had to the bolts 27 to unscrew them from the casting 25 and thus detach the shell along with all of the other elements supported thereby. Screws 29 are threaded into the heads of the bolts 27 to detachably connect said bottom plate to its shell.

A circular spreader frame 30 is utilized to support a plurality of heaters 31, which may be of any conventional type employed in permanent hair waving and the cords 32 of which are suspended from supporting devices generally indicated by the numeral 33, which are arranged about the periphery of the frame 30 in staggered relation, as best illustrated in Figure 2. These supporting devices 33 will be later described in detail. In order to mount the frame upon the head of thev machine, intersecting and radially extending arms 34 (Figure 4) for the frame are provided and the inner portions of said arms are extended through notches 35 formed in the upper peripheral edge of the j bottom plate 28.

` Means are provided in connection with the invention for directing a downward current of air onto the heaters 31 so 'as toreduce the eHect of heat radiation and thereby render the operation of waving the hair more comfortable to the subject. lThisv means comprises a fan 36 and its motor 37, the casing of which is detachably secured, by screws 38, to the bottom plate 28 of the head from which said fan depends. A protective-cage 39 is provided for the fan 36 and in this cage there is mounted a conical deflector 40 disposed in the path of the current of air created by the fan 36 and thereby adapted to divert said current of air'outwardly and downwardly toward the heaters 31 which 'ffire arranged in encircling relation to the The electrical connections for supplying current to the various hea-ters 31 will now be described and in this connection it is to be noted that each heater is separably connected toy a common source of current supply. To this end, yan annular insulating band 41 is suitably secured in encircling relation upon the shell 26 and two conductors 42 are extended around said band from within the shell 26, an opening 43 (Figure '5) being formed in the shell for this purpose. At the point where the conductors 42 extend through said opening the also pass through an insulationblock44 (igure9) which is secured to the'shell 26 and against the hand 41 by means of screws 45, an insulating plate 46 being fastened to the interior surface of the shell byA the Vnuts of the screws 45. This block 44 is, in reality, a blank constructed similarly to to the annular row of connecting members, presently to be described in detail, so as to present uniformity of appearance to said row when the. machine iscompletely assembled. On the portions of the conductors 42 Vwhich extend eXteriorly ofthe 'shell 26 thereare mounted, by 'soldering or otherwise attaching, a plurality of sleeve-like contact elements 47 arranged in spaced groups, a pair of'vertically aligned elements constituting each group when the conductors are properly arranged about the shell. In assembling Athe supporting head and associated elements of the machine, the conductors 42 are first held against the insulating band 41 adjacent the opening 43 and one of theconnecting socket members 48 forming part of'a separable connector is then mounted upon the first pair of contact elements 47 adjacent said opening, said member 48 being provided therethrough with two'openings 49 for receiving said elements. A third intermediate opening 50 isprovided in the member 48 and through this opening there is eX- tended a screw member 51, the innerf endof g f which projects through align-ed openings 52 formed in the shell 26 and insulating band 41. Vith the bottom plate 28 of the shell removed at this time, a nut-53 is threaded upon the inner end of thescrew 51 and engaged directly With the inner surface of said shell. The screw member 51 is provided with a socket 54 to receive one of the prongs of the plug member of the separable connector previous- 1y rreferred to and which will later be described indetail, and constitutes a groundL connection whereby the heater which is joined to the member 48 will be grounded through the machine. The vertical or side edges of the connecting members 48 are ali 1 1.

VThis operation is 'continued around the shell '1" 26 until the required number of connecting members e8 for the various heaters are in position. l/Vhen this has been done, there is still left a blank space in the annular row next adjacent the insulation block lll and on the upper side thereof, as viewed in Figure 7. This space is utilized Jrior the reception ot another socket member for connecting tie motor 37 ot the tan to the source ot current through the conductors 56, which also extend through the opening e3 in the shell 26. The socket member 55 is illustrated in detail in Figure S and is shown as provided with openings 5T for receivingl a pair ot the contact elements al' and a third opening 5S through which a screw 59 is passed, the inner end of said screw projecting through the .shell and a nut GO being threaded upon said screw and against the insulating plate 4:6. rllhe mount-- ing of the various socket connecting menibers having been completed, the bottom plate 28 ot the supporting head may now be secured in position by means of the screws 29, following which the motor and its tan are fastened to said bottom plate by the screws 38.

The cords 32 ot the heaters, each of which contains three conductors, are electrically connected to plug members generally indicated by the numeral 6l (Figure 2) and shown in detail in Figures 13 to i6. Each of these plug members is common to two cords 32 and is adapted to be plugged into one ot the connect-ing members 48. Specically, the plug member 6l comprises a pair ot coiiipleinental sections G2, each oi which is vided upon its interior surface and anjacent the longitudinal edges thereof with prong-receiving grooves 63 and @e and an inteimediate prong-receiving groove 65. At the inner ends ot each ot the grooves 63 and 65 there is `formed an enlarged circular recess G5, while in the bottom of the groove 64 there is provided a small circular recess 67. Three prongs 68, SQ and PZO are provided for inakthe various connections, the intermediate prei g being used as a ground connection lor the third wire of each oi' the cords 32 joined to the plug member, prong 69 be'ng insertable into the socket 5e of the screw 51 which is grounded to the shell 26. At the inner end of each ot the prongs the saine has mounted thereon a terminal screw 7l, to each ot which is connected two of the conductors ot' the pair ot heater cords to which the plug member is common. lllhen assembling the plug. two ot' the prongs, such as the prongs GS and are laid in their respective ,1y-grooves with the heads ot the screws 7l engaging in the enlarged recesses 66, while the tl ird prong positioned in its groove with the small end ot the screw 7l extending into the recess G7 ot the groove @el so as to prevent longitudinal shitting of the prong in its gro ve. The grooves ot each section 62 are slightly larger than the portions of the prongs which they receive in order to permit of a certain amount of lateral movement of the prongs, after the plug has been assembled, whereby they may be more easily ali gned with and inserted in aconnecting member e8. .fitter position1 ing the prongs in one of the sections 62 as described, the other section ot the plug may be placed over the first-named section and 4% extending` Jthrough the sections. By making the two sections G2 ot exactly the same construction, it will be apparent that the enarged recess 66 adjacent the edge ot the secy tion 62 1i 1 containing the prongs will receive the head ot the screw 7l carried by the prong 70, while the small recess 67 in the groove (ill will receive the small end ot the screw carried by the prong 68, the inner recesses 66 ot the two sections being then opposed. With these two latter recesses opposed, other means than the small recess 6? must be provided in order to prevent excessivel longitudinal or inward shitting ot the prong 69 iii its groove. To this end, said prong is provided with an annular flange 73 w ich engages a shoulder 74 termed in the groove 65 of each ot the sections 62.

in order to suspend the cords 32 from the frame 30 in such a manner as to relieve strain upon the cords by pulls thereon in dii'erent directions when manipulating the heaters. aud also to permit ot vertical adjustments oi' the cords and, consequently, of the heaters, the devices 33 are mounted in staggered relation on the inner and outer :faces ot the annular frame 30 and extend laterally in the plane thereoi". Each oit these devices, as shown in detail in Figures 10 and l1, is in the form of a gimbal and comprises a substantially lJ-shaped bracket 7 5 made of resilient material so as to permit of relative lateral movement ot the arms of the bracket. The bight or" this bracket is connect-ed to the trame 30 by a swivel 76 in order to permit ot a rocking or swinging movement ot the bracket about an airis which extends radially o'f the trarne. Adjacent the outer endsot the arms oit the bracket ,75, the saine has mounted therein a pair of rocking coopergtiiig cord-engaging and clainpiiigpinemb'ers 1,' and 48, cach being oi arcuate i'orniation and having a trunnion 'Z9 extending through an opening in the adjacent arin of said bracket. The two member 7T and 78 are held in cooperative relation, when a cord is not engaged therewith, by a pin on the former member extending into a recess 8l in the latter member. The outer portions ot the members 77, 7S are curved away troni each other to provide a. flared entrance 82 into which the cord 32 is inserted when positioning the same between the clamping members. As this is done, the members will be enen secured thereto by screw fasteners 72 i into the openings ioc manner upon the section 2l-of the standard and containing therein a time switch, generally indicated by the numeral 83 and being of any well-known design, which will control the automatic shutting oil of the current to the heaters 3l at the end of a predetermined interval of time. rlhis time switch includes a dial 84, a portion of which projects from'the casing 8:2 (Figure l) so as to permit of a manual adjustment thereof to set the mechanism for the desired interval of `time that the current is to flow to the heaters.. Afterthis setting is accomplished, the switch arm 85 is thrown to close the circuit to the heaters from the source of supply which is connected to the time switch through a three-wire conduit 86 and plug 87, one of the wires of this conduit being a ground connection joined to the casing 82 at 88. The control for starting the A motor 37 and regulating the speed of the fan 36 is a rheostat 89 mounted within the casing 82 and having an adjusting knob 90 projecting from the casing, the two conductors 56 being connected to said rheostat. A voltmeter 91 is electrically connected across the conductors for the heaters and constitutes a detachable part of the control assembly, said voltmeter having for this purpose a pair of prongs 92 insertable into the topof the casing 82.

If desired, the upper end of the standard may have mounted therein a small incandescent pilot lamp 93 enclosed within a detachable tip 9-l and connected by conductors 95 to the heater conductors, whereby the lamp 93 will be illuminated as long as the circuit for the heaters is closed.
