9 Claims.

The present invention relates to permanent hair-waving apparatus and has for an object the provision of a means that initially imparts the'ultimately sought or desired wave to the *5 hair, thereby eliminating the need of any subsequent setting of the waves.

Another object of the invention is to provide apparatus for the aforestated purpose which is "easily zand quickly operated, and in which the IO-wave forming units have relatively larger cal5-though not necessarily limited, to the use of steam as the heat supply for baking the hair -waves.

These and other objects are attained by the means herein described and disclosed in the accompanying drawings, in which:

-40 Heretofore the so-called permanent waving of womens hair has consisted essentially in forming a multiplicity of coils of hair strands in tightly'rolled coils or spirals upon suitable mandrels or winders andbaking the hair to impart 45 a frizzled orkinky condition to the hair which is then set in waves by a separate subsequent operation. This latter operation is repeated from time to time, particularly because the washingzor shampooing of the hair makes it lose the former wave but allows the kink of the individiualLhairs' to remain over'a long period of time. The repeated finger waving or setting of the so called permanently waved hair is a source of frequent expense and loss of. time to the users 255 OfJthecoifi'ures of this kind.

The present invention avoids the necessity of having the hair set or finger waved by providing a novel means whereby the permanent wave operation initially imparts, substantially or in some cases exactly, the ultimately desiredxwave '5 to the hair and this wave persists for at least as long a period of time as the kinks or undulation in the individual hairs as treated by the croquignole or other known permanent waving methods in use up to the present time. 10

The apparatus of the present invention comprises generally a support means adapted to detachably and adjustably support a suitable number of novel hair waving units and a suitable heat source for baking the waves of the hair in l'5 the units.

While in the preferred form illustrated, steam is used as the baking heat medium, it is to be understood that any other heating meanssuch as electric heating units in the individual wayers may be employed.

The procedure for permanently waving hair of this invention consists in clamping previously softened, blocked ofi bunches of hairs, hereinafter referred to simply as strands of hair, atiiz spaced intervals along the length thereof between clamping means or members that are adapted to impart curvature thereto in one direction, then longitudinally shifting adjacent clamping means longitudinally in opposite directions, then sub- 130 jecting the hair, thus stretched into desired wave form, to a suitable baking operation. Each hair of each strand thus has the ultimate contour desired in relation to other hairs of the strand so that the head of hair thus treated may have the usual softening solution washed from it and then merely dried and combed whereupon the hair assumes the desired waved form.

Various styles of hair dressing may be. obtained by the means of the invention.

The hereinafter described structure represents one embodiment of the invention that iseasily and rapidly operable, requiring possibly less positions. The rods I4 have swiveled friction connection at l5 with the plate l2 and these are made up as pairs of telescopically adjustable members, with a detachable swivel connector l5 at the end for ready attachment and detachment of the complementary end of stems ll of the individual waving units l8. Any suitable steam supply may be used for example, as diagrammatically shown, a low pressure return flow system indicated generally at N.

The hair waving units l8 of the invention are preferably made up of box-like casings each having a bottom 20, longitudinal side walls 2|, top end wall 22, and bottom end wall 23. The casings may be of light-weight cast metal or of formed sheet metal and are provided along the free edge of the side and end walls with a continuous flange 24 which is adapted to receive between it and a complementary flange 25 on the cover 25, a portion of a compressible gasket 27 which may be L-shaped in cross section and secured interiorly of the cover as may be best seen in Fig. 3. Intermediate the opposite ends of the flanges along end wall 23, one or both of the flanges are cut away slightly to form a shallow way as at 28 where the gasket 2'! seats upon a gasket 29 thereby forming a tight but yieldable clamping seal for the way and for clamping looks or tresses of hair therebetween without danger of cutting the hair when the cover is closed and clamped upon the casing.

Interiorly of the casing is a longitudinal shaft 30 journalled at or near its opposite ends in transverse partitions 3! and adapted to be rotated by a removable crank or winding key 32 which is insertable in a hollow tubular nipple 33. A series of short worms 34 are concentrically fixed on the shaft 30 and these mesh respectively with worm wheels or gears 35 which are secured on the ends of transversely extending adjusting screws 35 and which screws are journalled at at least one end, in one of the side walls 2! of the casing. The series of worms left handed and right handed threads or teeth, respectively, so that the successive screws 36 are turned in opposite directions when shaft 30 is rotated in either direction by means of the winding key 32.

The winding structure just described has associated herewith a series of clamps, one for each of the screws 36. The lower half of each clamp comprises a pair of vertical walls 31 which may be substantially rectangular about three sides thereof and having an arcuate cut-away top edge in which is seated and secured an arcuate or trough-like plate 38. The end walls 31 are notched as at 39 so as to guidedly support the structure upon ribs 45 of partitions 4| that are disposed transversely intermediate the top and bottom of the casing. Each pair of walls 31 has concentric threaded bores 42 in which the screws 36 engage so that upon actuation of shaft 35, the bottom section of each hair clamping device is shifted transversely within limits between the side walls of the casing. The top or complementary section of each of the hair clamping members comprises a second arcuate plate 43 which is of shorter radius than the lower plate 38 so that when the two are pressed together either directly or upon an intermediate resilient pad, the clamping or pressure contact is greatest at the bottom of the trough or plate 33. A resilient or slightly yieldable pad which may be an arcuate pad of rubber 44 is normally seated on the lower arcuate plate 38. The upper clamp 34 are alternately equipped with plate 43 in operation seats upon this pad and the interposed hair and clamps the hair in a transverse line, leaving that portion of the hair that is adjacent the free edges of the complementary curved plates sufficiently loose to permit of stretching and slight shifting of the hair between said edges of the complementary plates. The structure is preferably arranged as may be best seen in Figs. 2 and 3, so that the upper clamping plate has a hinged connection adjacent one end with the lower clamping plate and an adjustable latch is provided upon the free end of each of said upper clamping plates so that varying quantities of hair may be laid across the open clamps and subsequently clamped transversely while that portion of the hair intermediate the clamped portions may be free to be moved and stretched.

The hinge connection between plate 38 and plate 43 may be constituted in each instance by merely fixing the opposite ends of a pin 45 in the spaced walls of the curved plate 38 after passing said pin through perforations 46 in the plate 43. The latch means for clamping the free ends of plates 38 and 43 together consists of a latch bar 4i pivoted on a pin 48 which has its opposite ends fixed in and terminating as at 49 in the curved wall of plate 43, said latch bar 41 having an integral perforate finger 55 upon which a substantially U-shaped latch 5! is pivoted on a pin 52. A spring 53 associated with finger 50 urges the latch 5! about its pivotal mounting at 52. In manipulating the upper clamping plate 43 relative to its complementary plate 38, the curved end 54v of latch bar 41 is engaged by the fingers of the hand and pressure of the thumb at the same time is directed on the overhanging portion 55 of the latch to move the same about its pivotal mounting 52 against the resistance of springs 53. As soon as the lower offset 56 of latch 51 has been moved clear of the bottom edge of plate 38 and wall 37, lifting movement of the fingers will raise plate 43 to the inoperative position as illustrated in Fig. 2.

To insert the hair in the hair waving units, the entire series of clamping devices are unlatched and folded back in the position characteristically shown by the two clamps in Fig. 2 after actuating the shaft 30 until adjacent clamping devices have been moved to their respective opposite limits of movement in one direction. With the clamps open and in this extreme position, for example, as shown in Fig. 5, a large tress or series of adjacent tresses of hair that has been previously treated with a softening solution is progressively clamped in series of clamps in the unit by entering that portion of the hair which is closest the head across the open portion of the way 28 and then stretching the hair lightly across the first open clamp plate 38 on top of the resilient pad 44 and then folding the clamp plate 43 across this portion of hair and manipulating the latch so that the hair is clamped tightly in the bottom of the trough formed by the plate 38 and its resilient pad. The remainder of the hair is then stretched lightly across the succeeding open clamp which is then closed in the fashion just explained, thereby rather tightly stretching the hair between the two clamped places over the top of the intermediate partition 4|. This operation is repeated either until the end of the hair is clamped or until all of the clamps in the unit have been filled, in which case any remaining length of hair may either be folded back over the closed clamps or wound upon a croquignole winder 5'! which is optionallymade part of the waving unit of the invention in order to provide for the taking up and curling of excess length of hair and for the purpose of placing some additional tension on the clamped hair. In this position the tress or lock of hair operated on would extend longitudinally from end to end of the casing with a series of uniform dips therein. The winding key or crank 32 is now inserted through the hollow nipple 33 onto the angular end of shaft 30 whereupon the shaft 39 may be turned causing each of the clamping members to move transversely to its opposite limit of movement within the casing. The hair would then assume the position shown characteristically in Fig. 6, the hair between the clamped portions in the bottom of the clamping members being stretched and moved laterally or transversely so that the characteristic form or somewhat zigzag curvature that is attained by the so-called finger waving process is initially imparted to the entire tress or group of tresses within the hair waving unit Another hair waving unit would be applied in a like manner and in a corresponding position to an adjacent group of locks and so on until the desired amount of hair on the head of the subject has been clamped and stretched to the approximate form of the ultimately desired wave. As each Waving unit is filled and the hair therein set to the position characteristically shown in Fig. 6, the cover 26 is applied. The cover fastening means may be constituted by a rod 58 mounted on oifset lugs 59 on the bottom end wall 23 and a pair of hook lugs. Bil on the cover 26 whichv together form a readily separable and readily engaged hinge. The cover is then folded snugly onto the casing with the gasket material 21 forming a tight seal between the fianges of the cover and easing whereupon a pivoted hook 6| carried by the cover is engaged about the interiorly fiuted stem I! on the casing. The end of the stem I! may then be connected by inserting the fluted plug 62 of the swiveled clamping member iii to the end of one of the telescoping rod members l4. The waving unit I8 is thus universally adjustable relative to plate l2. After the entire head of hair has been treated in the foregoing manner and all of the hair waving units l8 have been filled and connected with the plate l2, a branch steam supply tube 63 from steam supply line 64 of the source i9 is connected as by a tapered friction connection to the nipple 33 from which the crank 32 is removed. The cover 26 carries a tube 65 which terminates near the bottom end wall 23 of the casing so that a complete circulation of low pressure steam is assured and so that no excess amount of condensation can accumulate within the hair waving unit. Tube 65 projects beyond the cover and receives the detachable branch return tube 66 which is connected with the steam return pipe 81.

The steam is then circulated through the several supply and return tubes for a sufficient length of time that, in the opinion of the operator, is sufiicient to bake the hair undergoing treatment whereupon the steam supply is shut off and the hair is removed successively from the several units by removing the cover and releasing the latches of the clamps, etc.

By the proper initial positioning of the several waving units, the hair which has been set and baked in adjacent units will naturally assume the desired relationship one look to the other and this relationship of all of the treated blocks will persist until such time as the natural lengthening of the hair bygrowth makes it advisable or desirable to be again treated. Thus, it will be noted that the so called setting of a permanent wave that is characteristically required from time to time is entirely eliminated so that the person may repeatedly wash or shampoo the hair and merely comb it after drying in order to attain a perfect coifiure. A considerable savingin time and money is effected by the use of the herein described method and apparatus for permanent waving.

The devices of the invention are not to be considered as limited to the exact details of construction shown since these are readily subject to modification. The "novel method of permanently waving hair in the form of the ultimately desired wave can be used for a wide variety of styles of hair dress and in the hands of experienced operators the character of the waves themselves may be modified and blended on the same head of hair so that it is possible to produce artistic creations for the individual or to reproduce an established style with great accuracy.

The operation of the device has been explained in connection with the description, of the structure. The procedure for waving hair by the herein referred to apparatus consists in first blocking off or dividing the entire head of hair into suitable amounts that are to be inserted in the individual waving units, then placing a felt pad or other protective device about each block of tresses closely adjacent the scalp and then treating the tresses with a suitable softening solution, e. g., oil and ammonia. Sachets are not needed. After these preliminary steps the individual blocks of hair are now ready forthe waving operation. This consists in first transversely clamping the straightened tresses at intervals beginning close to the scalp end thereof in such manner as to produce a longitudinal succession of dips, the tight transverse clamping being in the bottom of such dips while the hair intermediate the clamped portions is snugly stretched over an intermediate barrier.v .Any excess length of hair beyond the desired number of dips may either be left free or wound up into a roll or curl. The clamped portions of the hair are desirably disposed all in the same plane. These clamped portions are now shifted in alternate opposite directions thereby increasing the distance between adjacent clamped portions and thus imparting to the dips a transverse sinuous wave. The composite of the clips and waves in the tresses imparts to them the general character of wave that was heretofore attained by the socalled finger waving with the aid of a gummy, so-called wave set solution, as a subsequent operation after the previously known permanent waving of hair.

With the hair clamped and stretched to the ultimately desired form, the tresses are subjected to the baking operation which renders the waves permanent. This is the final step in the procedure. No wave setting operations or solutions need be used at any time during the normal life of the wave which is comparable in all respects with the duration of the relatively unorganized kinky or wavy condition of the individual hairs when waved by the heretofore permanent wave processes.
