63 ALEXIS ZACHARY BY FIG.35

ATTORNEY States This invention relates to improvements in devices for beautifying the hair of the human head; and especially implements by which such hair is treated for permanent waving and attractive styling, such as producing curls and ringlets. My invention is well adapted for use in dressing the hair of women, in conjunction with the standard lotions now widely employed for such purposes; so that the curls and ringlets are enabled to maintain the desired shape for relatively long periods.

An important object of this invention is to provide forming implements that can be easily manipulated to produce, for example, curls and ringlets in the hair, and quickly removed without breaking any of the separate locks or deranging the decorative formations which are obtained by such means. The turns and coils in each tuft of hair when thus freed from the implements, can be readily secured with clips and the like to retain their form, while the attendant performs the necessary finishing operations.

Another object is to provide a hair treatingimplement by which the lotion used can be most advantageously distributed to all the hairs in the tuft which is disposed upon the implement.

In operations of this kind, the devices for imparting to the tufts of hair a finished ornate appearance, are such that they must be kept in place on the head till the task of the attendant is about completed. A considerable number of such devices are utilized for the head of each customer, usually proving bothersome and uncomfortable; and their presence frequently causes some of the locks in a tuft of hair to break and keeps a lotion from reaching all the locks and tresses in the tuft; hence the effect is not uniform and the final result more or less unsatisfactory. With my invention this objection is entirely obviated.

A further object is to provide forming implements that prevent the attendant from manipulating a patrons hair into curls and ringlets that are wound too snugly thereon. The curls and ringlets are all produced in a manner that enables the forming lotion to take full effect so as to give the best results. The implement can be used with equal facility in a beauty establishment or at home.

Other objects and the advantages of the invention are fully set forth hereinafter, and the characteristics of the improvements are defined in the appended claims. The drawings show several embodiments of the improvement, but this disclosure is explanatory only and variations in structural details may be adopted without departing from the essential design which contains my invention.

Referring first to the implement illustrated in FIG- URES l to 7 inclusive, I fashion a short bar 1 of suitable material, and of such shape that it has its thinnest part at the middle and enlarged ends 2. The bar or body 1 tapers and contracts along curved lines towards the middle from each of the ends. Alongitudinal groove 3 extends along the side of the bar through the ends, and receives a flat metal strip or'mernber 4 with reduced or narrowed end portions 5, each bearing a knob 6. In the member are L-shaped slots having parts 7 which extend lengthwise of the strip, and parts 8 crosswise, extending towards the outeredge of the member 4. The bar has pins 9 crossing the groove 3 engaging the walls of the slots. When the strip has the transverse parts 8 of the slots in line with the pins 9, the strip can be projected or retracted laterally in the slot 3; and when the strip has the longitudinal parts 7 of the slots in line with the projections 9, the strip can be moved lengthwise to hold this member in projecting position, and increase the infective thickness of the bar. The ends 2 of the body 1 have studs 10 which are traversed by the extremities of the slot 3, and are connected to the strip by rubber bands or loops 11, which tend to pull the strip fully into the groove. One end of the bar 1 has a rubber strip or band 12 fixed to it; and the free end of the band 12 has a cap 13 to be slipped over the knob 6 at the opposite end of the body 1. The band 12 may be attached to the body by means of a notch 14 in one end, as more fully described later in connection with FIGURE 13.

In operation, the operator detaches the cap 16 from the member 4 and wraps a tuft of hair around the body 1. The strip 4 is first manipulated into position to increase the thickness of this bar 1, as shown in FIGURE 1, and the hair is then wound upon the implement. When winding is finished the operator lays the rubber strip 12 on the turns of the hair to hold the turns in place and stretches this str-ip so as to slip the cap 13 over the knob 6 at the opposite end 2. This band overlies the turns of hair and keeps them in place on the bar 1. The tension of the band 12 pulls the member 4 lengthwise in the slot 3; the parts 8 of the slots come into registry with the pins 9 and the member can move into retracted position as shown in FIGURE 4. Thus the effective diameter of the implement is diminished and the hair of the subject is not wound too tightly and stretched around it. A permanent wave lotion can then be put on and will penetrate all the turns of hair very well. The rubber strip or band 12 can then be loosened by detaching the cap 13 from the knob 6 receiving it, the ringlet removed and the liberated turns of the hair secured in any suitable manner. With this device the body 1 can be left in the hair during further treatment or the ringlets taken oil the bar 1 and secured by a clip before the permanent wave lotion is put on. In either case the hair is finished by the neutralizing preparation and washing. Curls can also be formed by winding a tuft of hair spirally along the bar 1.

FIGURE 3 shows the member 4 with diagonal slots 15 instead of L-shaped slots as in FIGURES 1 and 2.

FIGURE 8 shows a body .1 tapering as before from ends towards the middle and the slot 3 has cam projections 16 and 17 therein near the ends 2. These projections cooperate with recesses or notches 18 in the adjacent inner edge of the strip 4a, so that when the cam portions are in line with these recesses the member 4a can be easily retracted. The reduced portion at one end of this member is encircled by a compression spring 19 between the adjacent knob 6' thereon and the body 1, and this spring normally acts to push the member 4a into position so that the recesses or notches 18 are out of position with respect to the projections 16 and 17, which will then cause the member 4a to project laterally from the side and the body 1. The slot or groove 3 between the ends 2 where it opens through one side has an efiective length a little greater than the member 4a between the reduced portions 5 and 5, so that the member can move longitudinally to the extent required in the groove 3. A sleeve of elastic rubber on the extension 5' may be used instead of the spring 19.

At the end of the body 1, having the end portion 5, the rubber band 12 is affixed at one extremity, and the free end of the band carrying the hollow cap 20, will fit over the knob 6' on the aforesaid portion 5 of the member 4a, which is encircled by the spring 19. When the cap 13 is detached from the member 4a the spring 19 will move this member 4 lengthwise and the projections 16 and 17 will move it laterally to increase the effective diameter of the body 1. The end portion 5 may have a collar 21 to limit the movement of the member 4a by the spring 19.

Hence when the operator winds hair on this implement, the cap 13 is first removed and the spring 19 will then automatically cause member 4a to slide longitudinally in the slot 3 so that the projections 16 and 17 push it outward sideways to the necessary extent. As soon as the tuft of hair is wound on the body 1, the band 12 is laid on to keep the turns from unwinding, and is stretched and the cap 13 again put on the knob 6. The tension of the band is enough to overcome the force of the spring 19. The member 4a is then pulled into position for the notches 18 to be in line with the projections 16 and 17, and the member 4a is then loose in the slot 3 and can move inward sideways to reduce tension in the hair on the implement. The turns of hair are treated and taken off the body 1 in the same manner as before. The slot 3 does not extend through the ends 2, which have enlarged central bores receiving the extensions 5 and 5.

The protuberances 16 and 17 may be separate pieces aflixed in the ends of the slot 3 by pins 22.

The implement shown in FIGURES 9 to 18 inclusive comprises a body 25 as before, with thickened ends and tapering from the ends towards the middle. In one side there is a long recess 26 with shoulders 27 at both ends, and in this recess is seated a member 28 which conforms to the general outline of the body 25. The extremities of this member have studs 29 that fit into slots 30 in the shoulders 27. These slots 30 extend radially so that the member 28 can be actuated laterally outward with re spect to the longitudinal axis of the member 25. A rod .31 is slidably mounted in bearings 32 at the ends 2 and extends along the bottom of the recess 26. This rod projects at one end and bears at said end a head 33. Surrounding the rod at the adjacent end of the device 25 is a recess 34 which seats a spring 35 engaging the head 33 and tending to push the head away from the adjacent end of the body 25. In the space 26 this rod has projections 31 and the member 28 has a longitudinal groove 37 on its inner face containing small hollows or notches 38 for admitting the projections 36. When the body 25 and .member 28 are assembled as in FIGURE 18, the studs 29 are in the slots 30 at the ends thereof closest to the longitudinal center of the implement and the projections 36 fit within the notches 38, When however, the rod 31 is moved to separate the head 33 from the adjacent end of the body 25, the projections 36 act upon the groove beside the recesses 38 so as to push the member 28 outward into the position shown in FIGURE 13; the studs 29 then being at the opposite or outer ends of the radial slots 30.

The opposite end of the body 25 has a recess or notch 39 extending into one end from the side thereof, and this recess is open through said end by reason of a slot '49 in said end. Into this recess the enlarged end 41 of the rubber band 12 can be inserted, this recess securing the band or strip 12 to the body 25 and allowing it to extend therefrom. At its opposite end the strip 12 has a cap 42 to which the strip 12 is secured in an enlarged end 43 of an opening of the cap and the cap has a recess or hollow 44 to such a size to fit over the head 33.

To use this implement the band 12 is detached from the head 33 and the spring 35 then moves the rod 31 so as to force the member 28 outward, and thus the etfective diameter of the implement is increased. A tuft of hair is then wound around the implement and then the rubber band 12 is disposed so as to overlie the hair and keep it in place, and the cap 42 is fitted upon the head 33. The tension of this band 12 now overcomes the force of the spring 35 and pulls the head 33 of the rod 31 against the boss 45. The projections 36 are thus again seated in the recesses 38 and the member 28 is free to move in upon the bottom of the recess 26, so that the tension on the hair is lessened. The turns of the hair on the implement are then treated as before, and as soon as the cap 42 is removed from the head 33 the turns of the hair can be taken off the implement. With this construction the hair is always properly adjusted on the implement, and cannot be too tightly disposed, even should an operator be careless and wind a tuft of hair too snugly around the body 25 and member 28.

In FIGURES 19, 20 and 21 the same kind of implecut 25 is shown tapering from the ends 2 to the middle; but this implement is thinner, especially in the middle portion to form smaller ringlets and curls, as at the back of the neck or wherever they may be needed. It is made with a long slot 46 extending lengthwise to the central portion, open through opposite sides of the body 25; this slot having notch 38 in the middle to be engaged by a central projection 36 on a rod 31a which is disposed in a longitudinal groove 49 in one side of the slot 46. This rod projects from one end of the body 25 and there has a head 33 engaged by a spring 35 as before. To the op posite end of the body the elastic band 12 is attached and this band will again have a cap 42 to fit over the head 33. When the rod is pushed in and the head 33 is against the boss '45 the projection 36' of the rod is in registry with the notch 36. This recess or notch 36 is deep enough so that now the middle portion of the member can be compressed to put the sides of the slot or space 46 almost in contact, but when the head 33 is pushed out slightly the projection 36 on the rod engages one inner face the slot 46 as to hold it fully open at both sides. Hence the operator in using this implement first disengages the cap 42 from the head 33 and winds the hair on the implement. Next the band 12 is laid on the hair and the cap 42 thereof is slipped over the head 33, again pulling the rod 31 inward. This causes registry of the projection 36 with the deep recess 38 so that the sides of the slot 46 can be pressed together. The implement will therefore yield somewhat if the hair is too tightly wound thereon. The hair is then treated in the usual way, with the band 12 then overlying all the turns of hair, and the ringlets can then be taken off whenever the band 12 is loosened from the head 33.

The implement of FIGURE 19 has also a nozzle 49 at one end connected by a duct 50 with numerous discharge openings 51 along its length. Four rows of such openings are indicated. The rod 31a is disposed in a wide groove 47 in one side of the space 46, and this rod will be narrower than the groove 47, and will be kept in central position so as to leave a passage at both sides of the rod, by a spline 48 which fits into a keyway in the bottom of the groove 47. Hence when the hair treating preparation is to be applied to the hair wrapped around the implement it is injected into the nozzle 49 and passes out through the openings 51, reaching every part of the tuft which is In some instances the head 33 of the rod sliding in the implement can have the form of a boss 52 with a flange 53 to which the rod 31b is united, and the boss 53 can have a crosscut 54 to receive a round head 55 replacing the cap 42 on the elastic strip 12. See FIGURES 24, 25 and 26. Any suitable means may be used to make sure that the ball 55 will be securely attached to the boss 52. Also instead of the strip 12, I can use an elastic strip 12a, FIGURE 24a, with openings 56 at each end. One end of this band 12a can be stretched so that the loop thereon will fit over the nozzle 49 and the other end can be stretched to enlarge the opening and fitted over the boss '52. In this instance the flange 53 will have a notch 56 to receive the band 12a.

In the implement shown in FIGURES 27, 28 and 29, the construction is the same as that shown in FIGURE 22 except that the elastic strip 12 is omitted. This implement has a pivoted arm 57 which fits over the member 28. At one end this arm or member is substantially semi-cylindrical as shown in FIGURE 29 and it is secured to one end 2 of the implement by a wire loop or yoke 58, the ends 59 of which pass through openings in the arm 57 and into bearing recesses in the end 2. At the opposite end of this yoke shaped member 58 is a roller 59 and the head 33 of the rod 5112 has a depression 60. Adjacent said one end 2 the arm has projections 57a at its sides with the openings receiving the ends of the wire loop 58.

In use the tuft of hair is wound on the implement with the arm 57 and member 58 swung outward, and the 67 rod 31b projected by the spring 35. The tuft is wound on and then the arm 47 is laid on the tuftof hair; the

.head 33 is pushed against the spring 35 with the finger,

and the roller 59 is slipped over the end so that the roller seats itself in the depression 60. A yieldable spring 61 in the body at the end to which the arm 57 is connected acts to hold this arm in folded position. The rod 31b is now retracted so that the projections 36 thereon will be in line with the notches 38 in the member 28 and this member can then be moved inward.

The various forms of hair treating implement described above can be used in beauty salons or in the home for permanent wave or hair styling. Breakage of hair is prevented and when the permanent wave lotion is put on the hair by means of this invention the hair contracts and the laterally movable member releases tension on the hair after the tuft has been Wound thereon, to lessen the risk of breakage, even if the hair has been dyed or bleached. It also prevents pull burns after a permanent Wave lotion has been applied to the hair, and burns at the nape of the neck when the hair of the subject is drying on a machine dryer. The lotion or neutralizer penetrates better, due to release of tension, and is distributed more evenly through the openings 51 and a much softer wave or curl results. In machine treatment the spring 35 and strip 12 can be omitted and the rod 31a and 311) are then operated by hand, and the risk of burns is fully obviated.

Of course the implement may be made in various ways, as by forming it in halves parallel to the outwardly movable member or portion controlled by the rod and riveting or otherwise securing these halves together. The implements of this invention can be used with a machine or for machineless hair treatments alike.

Of course various minor changes in the shape of the parts may be made without departure from the essential design of this invention.

In FIGURE 21 rod 31a may be turned worked by hand, also causing outward adjustment of movable member 28.

The curler shown in FIGURE 27 with pivoted clamping, arm 57 can be utilized for both machine and machineless permanent waving. Curlers for machine and ma chineless permanent Waving have diiferent types of ratchets or retaining devices that prevent these curlers from turning back or unwinding when hair is wound upon it. In such curlers the rod with knob 33 and the ratchet will each have to be in their proper place to insure correct operation. The ratchet will be put adjacent the boss 45 in FIGURE 27, and the head 69 will be on a rod 33 without the spring 35. The rod will be operated by hand with a suitable key, and the curler with assembled ratchet and head is seated in U-shaped prongs of a holder which is grasped by hand.

In the form of the invention shown in FIGURES 30 to 35 inclusive, the body 25 has enlarged ends which taper as before toward the middle; and carries the member 28, which is movable laterally to expand this implement in the same way as above-described in connection with FIGURE 13. The implement contains a rod 31c, which is like rod 31a and is in a groove, 47 as in FIGURE 20, with projections 36 thereon to register with recesses in the member 28 when this member is fully seated in the recess 29 of the body containing the bar 28. At one extremity of the rod 310, there is a square projecting portion 33a fitting a recess 34a, and at the other end of the rod and within the body 25, is a cavity 5012 containing a spring 1% which presses against a head 1% on the adjacent end of the rod 310, and normally acts to push the rod 310 so that the squared end 33a projects from the body 25. At said other end, the body 25 has an opening extending in as far as the spring 5% which is seated against a shoulder within this end of the body, the opening being indicated at 50c.

To the projecting squared end 33a of the rod 310, the

elastic cord 12 is attached, and a nozzle 49 is connected to the other end of this cord. This nozzle has a flange 52 and a bore 53 extending therethrough as above-described. The cord 12 is of such length that when the nozzle is not in the opening 50a, the tension of this cord is not exerted on the rod 310, and the spring 50b pushes against this rod to cause the squared end 33a to project farther out of the opposite end of the body 25, so that the projections 36 thereon will expand or move laterally the section 28. On the other hand, when the spring 12 is stretched and the nozzle 12 is inserted into the end of thebody 25, the cord 12 overcomes the spring 19a so that the rod 31b is pulled inward and the projections 36 thereon register with the recesses in the section 23, as above-described, and this section is then released and free to move inward.

In practical use, this form of the invention is handled as above-described. First, the nozzle 49 is withdrawn. The spring 1% pushes the rod 310 to the right to expand the section 28, and then the hair of the subject can be wound upon the implement. When the winding is finished, the cord 12 is stretched and the nozzle 49 is attached to the body by pushing it into the opening 500 to the cavity 5%, rod 31b is now pulled in and the section 28 is released to lessen the thickness of the body 25, so that the turns of the hair around the body are wound less tightly. Next, the fluid for treating the hair is injected through the nozzle 49, and flows through the space containing the spring 19a past the head 1%, and along the sides of the rod 31b and out through the ducts 51.

This implement is used as a curler for cold waving and for permanent waving and gives excellent results. The head 19b has recesses 190 so that the cavity 50b is in communication with the groove 47 in which the rod 31b is seated.

When no liquid is to be injected into this implement, and it is to be used for hair dressing or styling, the nozzle 49a and cord 12 can be omitted. I then attach to the squared portion 33:: of the rod 3112, an arm or clip 57 which is similar to the arm or clip 57 shown in FIGURE 27 and is connected to projecting 33a end of the rod 31!; by pivot pins 57a (FIGURE 35) and bearing ears 570 on this arm, so that this arm can be swung inward and outward. This arm is long enough to reach the opposite end of the body 25 which has the opening for the nozzle 49, and there the arm is bent cross-wise and terminates in a knob 62. The nozzle 49 and ducts 51 can be omitted.

In use, this arm is lifted so that the hair can be wound freely about the body 25 and section 28, which is then pushed outward by the projections 36 on the rod 310, because the spring 19a is then free to expand and move this rod to the right, projecting out farther the squared end 33a. After the hair is wound on the implement, the arm 57 is pulled to force the rod 310 inward against the spring of 19b, freeing the section 28 so that it can move inward, and remove any tension on the turns of the hair, and the end of this arm bearing the knob 62 is slipped over the end of the body 25 which has the opening 501: to the cavity 50b, and the knob 62 seats in said opening. The rod 310 is thus held at the inner end of its movement and the spring 19a remains compressed during the operation of treating the hair, and the hair can be unwound from. the implement when the arm 57 is again lifted outward.

Having described my invention what I believe to be new is:
