'1 This invention relates to a hair -curling device including a pair'o'f elements cooperable in their respective actions to permit the user thereof to 'forma'curl, to press the same 'flatly against the head and to insert a number of conventional bobby pins for holding the curl intact, the primary objectbeing'to improve upon the unit disclosed inmy co-pen'ding application, Serial No. 88, 184, filed April 18, 1 949, and now-granted as 'Patent'No'. 2,535,223;

This is a continuation in part of my said copending'appli'cation and has "for its most important object to presenta device so formedand arranged as topermit quick and easy removal "thereoffromtheformed'curl, clearing the aflixed pins,leaving no uncomfortablepart of the device Within'the curl or'otherwise affikedt'othe hair of 'the user'and eliminating all possibilities of entanglement with the hair.

It is an important object of the-present invention to providea hair curling-device that includes a pair of relatively 'sliiiable members, one of the members being elongated and having arplurality of opposed slots disposed longitudinallyadjacent one'end thereof, the other'member comprising 'a'collar that is frusto-conical to cause all loose strands of hair to slide freely therefrom during use-thereby preventing reveling and snaringjof the hair thereabout.

Another important objectof thepresent invention "is to provide an elongated member having two pairs of longitudinally "disposed slots extending inwardly from one end'thereoflthere being a collar slidable on the member that is in turn provided with'a'number of wedge-shaped exten- 'sions, defining-a slit'for-each of the slots of the member respectivelyfo'r receiving apair of bobby pins 'in crossed relationship to be afilxedto the curl in holding relationship thereto.

Another object of the present invention includes the particular way in which the collar is held against rotative movement'fwith respect tothe elongatedmember upon which the collar is slidably mounted.

Other more minor objects including details-of construction will be made clear or become apparent as the following specification progresses, reference being had to the accompanying drawing, wherein:

Fig. 7 is'a transverse; crosssectionalview taken on line VII'-'-VII of Fig. 4' locking'in tli e direction of the arrows.-

The hair curling'de-vice shown-in' the drawing, includes an elongated member-10) having 's'lidably mounted thereon a relatively-short frusto conical collar [2. "As' shown particularly in Figs. ""5 and '7, the transverse, cross-sectional contours-of the member I0 and the'collar' I2, are'preferabIypircular, but not necessarily so-andother configurations may well serve the purposes "hereof.

The member H] maywell besolid substantially the entire length'thereof if desired, but for the interest of lightness, the sam'e' ha's been illustrated as tubular, one end thereof serving "as a finger grip and providedwith=a-knurled'annulus it to prevent slippage. Any'-metallic'substance may be usedto form-the member lflas well-as the collar I 2, but it has been found that a'plas'tic material is quite suitable, particularly for collar 1 2, because of its lightness, cheapnessandattractiveness.

One open end of the 'member [0 oppositet'o the grip I8 is provided with aplurality o'flohgi'tudinally disposed, inwardly extending 'slotspithere beingtwo pairs ofopposedsl'ots' l4l '6 tindZQe- 22,--presentin'g'fourfingers 24, 2'6; 28 and 30. "All of the fingers'have their'endscurved inwardlyas at 32 and, as is clear in the-showing ofpollar l2 by dotted lines in 'Fig; 6,-the"lengthof all of the slots I 4l 62 il--2 2 is'substantially greater than the length of the collar 12.

Collar I 2 has an inside *diameter sub'stantially the same as the-outsidediameter'of the member H] for free sliding movement on the latter throughout the length thereof between the grip l8 and the ends32 of fingers 24, 26, 2.8 and 30. The. collar I 2 is. provided with four elongated slits 33 extending longitudinally "with rwpect thereto and equally spaced therearoundrto the end that one of such slits 38 -is provided"foreach of "the slots I4, l6, 20 andl22 respectively. The spacing of the slits 38 is such as the'bring-the-same in direct registering relationshipwith'a corresponding slot M, It, 20 or -22 -w-hen"=the sonar-+2 -is moved toward the-slotted end ofthe member '10, asindicated by dotted lines-inFi-g.'-6.-

Accordingly, though collar [2 is frusto-conical throughout its length, presenting a flat end 46 facing the knurled grip l8 and a flat base 42 facing the opposite end of member in, there is presented a solid annulus 44 circumscribing the tubular member ID. By virtue of the slits 38 of collar l2, there is presented a like number of solid, wedge-shaped extensions 46 integral with annulus 44 and on that face thereof opposite to end 40.

Each extension 46 is provided with a pair of opposed, parallel side walls 48. Thus, the sides of the extension forming the slits 38 converge as the member ID is approached. Additionally, each wedge 46 has a pair of opposed side walls 56 that converge as the inner face of wedge 46 is approached (see Figs. and 7), thereby providing each slit 36 with parallel sides adjacent member I 0. It is noted that in transverse crosssection, each wedge extension 46 has arcuate, concentric faces 52 and 54, the latter conforming to the shape of the finger 24, 26, 28 or 30 upon which it slides.

The slot M of the tubular member ID is appreciably longer than the slots [6, 26 and 22, terminating adjacent annulus [8. An inwardly projecting lug 56 on annulus 44, slides within the slot I 4, holding member l0 and collar l2 against relative rotation and permitting movement of collar I2 to the position shown in Figs. 1, 4, and in full lines in Fig. 6 near annulus IS with slots 16, and 22 out of register with their corresponding slits 38.

When the curling unit is placed in use in the manner illustrated in Fig. 1, the collar i2 is moved to that end of the member l6 adjacent the grip portion l8, the hair is gathered into a .bundle 58 and the end thereof is passed through the aligned openings I4 and [6 or 20 and 22 of the member Ill. The curvatures 32 of the fingers 24, 26, 28 and 30 renders such insertion of the bundle of hairs 58 relatively simple. With the ends of the hairs caught within the member H), the operator grasps the grip l6 and rotates the member [6 on its longitudinal axis to coil the length of hairs 58 about the slotted end of the member I 0, as shown in Fig. 1. After the curl has been formed in this manner, the member 10 is moved to a position substantially perpendicular to the head of the user as shown in Fig. 2,

to position the curl 60 in a fiat condition with respect to the head.

While holding the member H3 in such perpendicular relationship to the users head, the collar [2 is moved longitudinally along the member l0 toward the slotted end thereof and as pressure is applied to the collar l2 to force the curl 60 flatly against the head, such curl 69 is held against displacement until pins 62 and 64 can be placed on the curl 60 to hold the same.

Pins 62 and 64 are opened in the usual manner and one leg thereof is passed on one side of the curl 60 adjacent the head, while the other leg of the pins 62 and 64 passes through the aligned slits 38 of the collar I2 and consequently through the aligned slots 14 and IE or slots 26 and 22 as the case may be. Since the length of the pins 62 and 64 is appreciably greater than the diameter of member ID and collar 12, the free ends of the pins 62 and 64 will project well beyond the periphery of collar I2.

As shown in Fig. 3, the pin 62 is first placed in holding relationship with the curl 60 and then the pin 64 is afiixed in crossed-relationship to the pin 62. Y It is a simple matter for the operator 4 to grasp the member l0 adjacent the innermost ends of the slots of member ID to hold the collar I 2 against sliding movement toward the grip l8 and to thereby hold the curl 66 flatly against the head, while the pins 62 and 64 are moved into place.

It is to be understood that while such operation takes place, the slotted end of the member I0 is held tightly against the head. After pins 62 and 64 are positioned in the manner shown in Fig. 3, both the member l0 and the collar l2 can be entirely removed because of the fact that all of the slots l4, I6, 20 and 22, as well as the slits 38 will effectively clear the pins 62 and 64.

The advantages resulting from forming collar l2 precisely as illustrated and above described now become apparent, particularly on viewing Fig. 2 of the drawing. It is virtually impossible when compressing curl 60 tightly between base 42 and the head to prevent strands of hair from extending over the face 52 of the extensions 46. By virtue of the smooth, ful y uninterrupted external surface of the collar 12, there is no chance whatsoever of entanglement to impede the complete removal of the entire unit from the curl 60. It has been found that in absence of this collar construction, raveling and twisting of the hair thereabout, make it extremely difiicult to dislodge the collar portion of the unit from the curl 60 that is bound and held tightly in place by pins 62 and 64.

The wedge-shaped s its 38, defined by inclined walls 48 and terminating in straight walls 56 facilitate the insertion of pins 62 and 64 and effectively guide the same into the slots I4--l6 20-22 of member It. And, the novel shape of collar l2 aids in handling thereof, making it easy to locate slits 38 and when the device is used without aid of a hair-dresser.

It has been found that the unit above described, can be either used by the skilled cosmetologist or by the home user and when placed in use, a plurality of curls can be formed quickly and easily with but little practice. There are no uncomfortable objects left in the curl aside from the holding pins and but one unit is necessary to form as many curls as desired. The device can be easily and cheaply manufactured and placed upon the market at an extremely low cost and need not be replaced from time to time by the user thereof because of the fact that use thereof does not damage the same in any manner whatsoever.

Many other advantages will emanate from the use of the hair curling unit forming the subject matter hereof and further, it is apparent that the same is capable of many changes and modifications and, therefore, while only one form of my invention has been illustrated and described, it is desired to be limited only by the spirit of the invention as defined by the scope of the appended claims.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. A hair curling unit comprising an elongated member having a number of pairs of longitudinally disposed slots formed therein and extendmg inwardly from one end thereof, the slots of each pair thereof being diametrically opposed; and a frusto-conical collar circumscribing the member and freely slidable along the length thereof, said collar having a slit formed therein for each of said slots respectively and in register therewith when the collar is adjacent said one end of the member, a, portion of said slits being x-shaped in cross-section.

2. A hair curling unit comprising an elongated member having a number of pairs of longitudinally disposed slots formed therein and extending inwardly from one end thereof, the slots of each pair thereof being diametrically opposed; and a frusto-ccnical collar circumscribing the member and freely slidable along the length thereof, said collar having a slit formed therein for each of said slots respectively and in register therewith when the collar is adjacent said one end of the member, the base of said collar being flat and facing said one end of the member, a

portion of said slits being V-shaped in cross sec- 15 6 tion and each having opposed side walls diverging as said base is approached.
