COMBINED SFINDLE AND CORQUIGNOLE HAIR WAVING HEATER Filed Oct. 51, 1929 INVENTOR ERNEST. G. UNGER Patented Jan. 10, 1933 UNITED STATES PATENT OFFICE ERNEST G. UNGER, OF BROOKLYN, NEW YORK, .ASSIGNOR TO HALLIWELL-SHELTON ELECTRIC CORPORATION, OF NEV YORK, N. Y., A CORPORATION OF NEW YORK OOMBINED SPINDLE AND CROQUIGNOLE HAIR WAVING HEATER Application filed October 31, 1929. Serial No. 403,899.

The invention relates in general to a combination heater for use in waving hair on a persons head in practicing both the cro-, quignole and spindle methods of waving.

It is the present practice in the hair waving art to provide two different types of heaters for use in such methods, one constituting a two-jaw spring gripping type designed to clamp the hair under treatment lengthwise between the jaws, and the other constituting a hollow tubular type for encircling a coil of hair when wound spirally on a spindle and for this reason identified as a spindle method.

The primary object of the invention is to eliminate the necessity of the operator using two forms of the heaters in the hair waving work, and to provide a single article of manufacture comprising a basic unit which may be used alone in practicing one method by the insertion in place of another unit constituting an attachment which may be used in practicing the other method and in this way a single article may be used selectively for practicing either method of wav- H1O.

ldroadly, this object of the invention is attained by using a croquignole type of heater as the basic unit and utilizing the jaw clutch spring in such heaters for the purpose of clamping between the jaws an additional plate which will coact with the jaws to form a cylindrical or other tubular form of heater for use in the spindle method. 35 In some methods of hair waving by means of the spindle method there is required a heating tube of greater length than is usually required in the croquignole method, and accordingly the present disclosure features the providing of a tube forming part of the attachment which will coact with the croquignole heater forming jaws to provide an extension or elongation thereof and thus provide a tubular heater of any requisite 45 length.

It is a usual practice to support hair waving heaters from the electric leads which supply current to the heater element contained within the shells which outline heaters of this character. In using croqui'gnole heaters, it is the usual practice to group the heaters about the head of the person under treatment with the heaters extending more or less horizontally and with their long sides in engagement with or tangent to the head. 5 In using the tubular heaters in the spindle method, the tubes extend more or less perpendicularly to the head with one end adjacent the scalp, or differently expressed, the axis of the heaters extends somewhat ra- 6 dially of the head and of course at varying angles to the vertically extending electric leads which supply the heaters. In order to provide for this variation in angular adjustment between the supporting electric leads and the combination heater herein featured, the invention features the use of heater positioning means between each of the supporting electric leads and the basic unit or that part of the construction which is common to both forms of heaters. These positioning means are designed to permit an easily manipulated, quick adjustment to the same with relation to both the suspending leads and the part of the device carried thereby so as to suspend the heaters in that angular position required for the most efficient practicing of the different methods.

Various other objects and advantages of the invention will be in part obvious from an 8 inspection of the accompanying drawing and in part will be more fully set forth in the following particular description of one form of mechanism embodying the invention, and the invention also consists in certain new and 8 novel features of construction and combina tion of parts hereinafter set forth and claimed.

In the accompanying drawing there is shown in full lines in Fig. 1 a view in side elevation of a preferred embodiment of the invention with both the basic and attachment units assembled to form a cylindrical spindle winder type of heater and showing in dotted outline the heater shifted relative to the supporting electric lead to dispose the heater in the position which it would be used when acting on a coil of hair adjacent the top of the head and heating the same by the spindle method. 1

Fig. 2 is a view in end elevation of the device as shown in Fig. 1 looking at the same from the left hand side of such figure and showing a portion of one of the handles broken away to disclose the manner of securing the heater positioning means to the heater; 7

Fig. 3 is a View in side elevation of the attachment unit'or filler shown at the lower portion of the two preceding figures and removed from the basic unit constituting the croquignole heater Fig. 4 is a view mainly in end elevation and partly in vertical transverse section taken on the line 44 of Fig. 3 looking in the direction indicated by the arrows, and

Fig. 5 is a perspective view of the attachment unit shown in Figs. 3 and 41.

Referring first to the showing in Figs. 1 and 2, it will be understood that the heater comprises essentially three 1on curved ' portions 10, 11 and 12 with their inner concaved sides 13 facing each other and coacting as shown particularly in Fig. 2 to form a cylindrical heater 1 1. The heater thus formed is provided with a slot 15 between the two members or jaws 10 and 11 but otherwise corresponding to conventional forms of hair waving heaters of the cylindrical type now in general use.

Considering first the cylinder forming members or jaws 10 and 11, it is a feature of this disclosure that they are pivotally connected to constitute a heater of the type comrent through wires contained in heater. supporting leads 26 usually depending from monly used in practicing the croquignole method of hair waving. In the instant case, each of the jaws 10 and 11 is provided with a laterally extending handle mounting plate 16, welded to the'outer face of the jaws 10 and 11. To the outer face of each of these plates is fastened a block of insulating material and which two blocks constituting a pair of han dles 17 and 18 extending parallel to each other and secured by fasteningmeans 19 to their respective plates 16. The handles 17- and 18 are disposed in parallelism for actuating the jaws 10 and 11 somewhat following conventional practices in this respect. The-jaws 10 and 11 are pivotally mounted toeach other by means of a pivot bolt 20 passed through opposed pairs of lugs 21 and 22 each pair extending in mutually overlapped relation from the opposite edges of the plates 16. A spring 23 is coiled about bolt 20 and has its opposite ends 2 1 in bearing engagement with the inner faces of the plates 16 adjacent their outer ends and acting thereon in a tendency to move the jaws 10 and 11 towards their closed clamping' position.

The'jaws 10 and 11 are provided with heating units contained therein and these heatmg units are supplied with electric curoverhead brackets and other forms of supports.

As shown in Fig. 2, the inner face of one of the handles 17 is recessed adjacent its outer end to provide a slot 27 and positioned in this slot is one end of an L-shaped metal pressing 28 constituting a heater positioning means. The portions within the slot 27 are enlarged as shown in dotted lines in Fig. 1 and the enlarged end is provided with an eye 29. A pivot pin or rivet 30 is passed through the eye 29 and through the handle 17 as more particularly shown in Fig. 2 for the purpose of pivotally connecting the means 28 to the handle and for securing the means in frictional tight engagement with the handle. In this way the handle and the positioning means 28 will be maintained automatically in whatever angular position they may be shifted as suggested in the full and dotted line showings in Fig. 1.

The outer end of the pressing 28 is bent at right angles to the part pivoted to the handle as shown in Fig. 2 to extend above and across the space formed between these two handles 17 and 18. This overlapping portion 32'is provided with a ring 33 through the eye of which extends the leads 26 and this eye is so designed that the leads fit therein more or less snugly so as to provide a frictional resistance to any tendency of the lead to shift freely through the eye. 7

The free edges 34 and 35 of the jaws 10 and- 11 are rounded as indicated in Fig. 2 so as to present a s1nooth,.rounded edge to the clamping-jaw heater when used in the crequignole method. v

The'attachment herein featured and particularly shown in Figs. 3 to 6 comprises ends of which project laterally beyond the plate 36 and engage the inner faces 13 of the jaws 10 and 11 to constitute as indicated in Fig. 2 means for limiting the closing movement of the jaws 10 and 11. It is appreciated also that clip 40 acts to prevent any outward or falling movement ofthe outer or left end of the attachment shown in Fig. 3 away from the jaws 10 and 11.

At the opposite or right hand end of plate 36, as viewed in Figs. 1, 3, and 6, there is provided a tubular extension 11 designed to form a prolongation of the tube formed by the parts 10, 11 and 12 as shown to the left of Fig. 1. The extension 41 includes a tubular part 4E2 of relatively small diameter and terminating at its outer end in a frusto-coniiio cal nose 43. The inner end of the extension 41 is enlarged over the diameter of the part 42 to provide a sleeve 44 having an internal diameter sufficient to telescope the adjacent end of the jaws 10 and 11 when held in their open position by the plate 36 interposed therebetween. The attachment 41 is secured to the plate 36 by means of rivets 45 passed through spacing blocks 46 fitted between the sleeve and plate shown in Fig. 4.

In operation and assuming for instance that it is desired to use the device in practicing the method of waving hair by the croquignolemethod, the attachment is withdrawn from its engagement with the jaws 10 and 11 if the attachment happens to be in place. This is attained by pressing the handles together against the action of the spring 23 to an extent sufiicient to release the clutching effect of the jaws on the attachment. The attachment is then slipped out of position by moving the same longitudinally to the right from the position shown in full lines in Fig. 1. The attachment can then be laid aside and the remaining part used conventionally as is usual in the use of croquignole hair waving heaters. During this use, the heater positioning means 28 is shifted into the vertically extending position forming a prolongation of the length of the handle as shown in Fig. 1, if not already in this position.

Should it be desired to use the device in the method of waving hair by the spindle process, the handles are pressed slightly together so as to open the jaws a distance sufficient to permit the insertion of the plate 36 between the rounded jaw edges 34 and 35 and shifted lengthwise until the jaws are seated within the sleeve 41. Releasing ten sion on the handles will permit the spring 23 to exert a clamping action on the plate 36 and thus act to hold the attachment in place and form the cylindrical type of heater commonly used in pract cing this method of hair waving.

As noted before, the heaters are grouped about the head in endwise engagement with the scalp and this necessitates an adjustment of each heater relative to its supporting lead to some set angle depending upon the position of the heater on the head. When using the device as indicated in Fig. 1, it is the practice to first locate the heater in its proper position on the head. and then by grasping the positioning means 28 it is possible to shift the same into the proper angle to permit the lead to fall vertically from its ceiling bracket or other supporting means. The heater is thus located in position to eliminate or at least to minimize any pull on the hair under treatment.

By means of a device of the character described, it is possible to provide one form of heater which can be used selectively in practlcing different processes of hair waving and in the practicing of which processes two radically different forms of heaters are required and in which each form of heater necessitates a positioning on the head different from that required by the use of the other heater. The device disclosed can be quickly changed from one form of heater to another without necessity of using any tools or readjustment of parts and the change from one form to another simply involves the sliding of an extra unit or attachment into position or the withdrawal of this unit from position on the basic unit. The electric heating units are contained in the part common to both forms of heaters so that there is no necessity of making or breaking an electric connection in changing from one form to the other. In those cases where different lengths of tubular heaters are required, it is simply necessary to provide attaching unit with different lengths of tubular extensions. It is obviously possible in case a tubular heater opened at opposite ends is desired to either omit extension 41 entirely from the attachment or to substitute therefor the nose 43 alone, or a plate or some other closure of the types now found on hair waving heaters of the tubular type. It is also possible to supply under the basic unit a set of attachments, each differing from the other in the character of tubular or other extensions provided.
