HAIR ROLLER Filed March 22. 1961 FIGB INVENTOR. E.W. SCH RODER United States Patent Ofifi ce 3 2 522 Patented Nov. 30, 1965 3,220,422 HAIR ROLLER Ernest Wiliiam Schroder, 117 Bluff Sh, Council Bluffs, Iowa Filed Mar. 22, 1961, Ser. No. 97,529 2 Claims. (Cl. 132-40) This invention relates to hair curlers, and particularly perforated hollow rollers upon which hair is wrapped, and in particular an elongated cylinder having a perforated wall with triple arm rods slidable in the ends and having knurled knobs on the outer ends with elongated inwardly extended spring clips mounted on the knobs and arranged to slide, selectively, through notches in ends of the cylinder for storage, or over hair wrapped around the cylinder for preventing unrolling of the curler, and thereby retaining the curler against the head with the hair wrapped thereon.

The purpose of this invention is to provide a hair roller having spring clips for holding hair wrapped thereon in which the spring clips are actuated to nested positions within the roller for storage, and wherein the clips are not separated from the roller.

With conventional hair curlers the hair is wrapped around the roller until the roller engages the head, and, with all of the hair wrapped on the roller a pin is placed through holes in the roller to prevent the hair unrolling, or a clip is attached to the roller and placed over the hair to retain the hair in a comparatively tight position upon the roller.

An operator in a beauty parlor places hundreds of such rollers on hair each day and every time a roller is in place it is necessary for the operator to reach down and pickup .a pin or clip as she places it on a roller.

With this thought in mind this invention contemplates a hair curler in which spring clips for retaining the hair wrapped on a roller of the curler remain permanently on the roller, thereby obviating the necessity of reaching down and picking up a pin or clip for each roller.

The object of this invention is, therefore, to provide a hair curler in which spring clips are actuated to storage 6 Another important object of the invention is to provide a hair roller in which the hair is retained in curling position thereon by clips, and in which the parts are assembled and taken apart without screws, bolts, or other fastening elements.

A further object of the invention is to provide a hair curling roller in which hair is retained rolled on the roller by spring clips carried by knobs at the ends of the roller and slidably mounted by rods extended into the roller in which both the roller and rods are perforated to permit circulation of air through the roller and also through hair rolled thereon.

It is yet another object of the invention to provide a hair curling roller in which the hair is retained wrapped around the roller by spring clips and in which means is provided for preventing accidental separation of the clips from the roller.

A still further object of the invention is to provide an improved hair curler in which hair is retained rolled on the roller and by spring clips slidably mounted on the roller in which the curler is of simple and economical construction.

Other and further objects and advantages of the present invention will be apparent from the following detailed description drawings and claims, the scope of the invention not being limited to the drawings themselves, as the drawings are only for the purpose of illustrating a way in which the principles of the invention can be applied.

Other embodiments of the invention utilizing the same or equivalent principles may be used and structural changes may be made as desired by those skilled in the art without departing from the present invention and the purview of the appended claims.

In the drawings:

FIGURE 1 is a side elevational view of the improved hair roller with one part broken away and parts shown in section, and with a spring clip holding knob at one end of the roller shown in an extended position in dotted lines.

FIGURE 2 is a cross section through the hair roller taken on line 22 of FIGURE 1.

FIGURE 3 is a cross section through the roller taken on line 33 of FIGURE 1.

While one embodiment of the invention is illustrated in the above-referred-to drawings, it is to be understood that they are merely for the purpose of illustration and that various changes in construction may be resorted to in the course of manufacture in order that the invention may be utilized to the best advantage according to circumstances which may arise, without in any manner departing from the spirit and intention of the invention, which is to be limited only in accordance with the appended claims. And while there is stated the primary field of utility of the invention it remains obvious that it may be employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specification, the same reference characters are used to designate the same parts and elements throughout, and in which the numeral It) refers to the invention in its entirety, numeral 12 indicating an elongated cylinder having perforations 14 therein,

numerals

16 and 18 indicating spring clips mounted in

knobs

20 and 22, respectively,

numerals

24 and 26 rods, Y-shaped in cross section, extended inwardly from the knobs, and

numerals

28 and 30 oval-shaped heads positioned on outer ends of the rods and designed to engage inturned flanges 32 on inner ends of the cylinder 12 to prevent accidental separation of the spring clip assemblies from the cylinders.

Each

knob

20, or 22, together with its respective rod 26 and its

respective head

28, or 30, can be termed a clip carrying member 35. Each clip carrying member 35 has an outer portion, which is its

knob

20, or 22, and an inner portion, which is the remainder of the clip carrying member.

The inturned flanges 32 have central holes therethrough, which are preferably cylindrical and are concentrically disposed with respect to the axis of the cylinder 12.

Each clip carrying member 35 has a bearing portion 33, which is received within the respective end of the cylinder 12, each bearing portion 33 having an outer surface, these outer surfaces being preferably cylindrical and shaped complementarily to the inner surface of the hole through the respective inturned collar 32, as best shown in FIGURES 1 and 2, whereby the cylindrical bearing surfaces 33 bear against the substantially cylindrical inner surfaces of the inturned collars or stop members 32, for rotation with respect thereto and in abutting engagement.

As the outer surface of each bearing portion 33 is preferably cylindrical and disposed longitudinally parallel to the axis of the cylinder 12, it bears against and is guided by the hole through the respective inturned flange on the cylinder. It will thus be seen that the abutting surface of the bearing portion 33 and the hole through.the respective inturned flange 32 are cooperatively shaped for guiding the bearing portion to be rotated in a circular motion about the axis of the cylinder 12.

The inturned flanges 32 are provided with notches 34 through which the

spring clips

16 and 18 extend in the nesting or storage positions, such as indicated by the dotted lines 36; and by drawing the

knobs

20 and 22 outwardly, as indicated by the dotted lines 38, the

rolled ends

40 and 42 of the clips may be inserted in the cylinder through the notches, or withdrawn from the cylinder for sliding over hair on the roller. The spring clips are mounted on the curler by inner end portions of the clips, also called right angularly disposed ends, 44 which are embedded in the

knobs

20 and 22, the remainder of each clip being called its outer portion the latter terminating in its outwardly rolled

terminal end

40 or 42.

The outwardly rolled

terminal ends

40 and 42 cause that surface of the terminal end which is adjacent to the cylinder 12 to be beveled and to incline outwardly toward the terminal end so as to ride up over rolled hair in use, as is common with hair clips. However, the spring clips may be mounted on the knobs or rod by other means.

The webs of the

rods

24 and 26 are formed with perforations 46 to facilitate circulation of air through the roller and hair rolled thereon, and the

heads

28 and 30 on inner ends of the cores are oval shaped to facilitate forcing the heads through the inturned flanges 32 on the inner ends of the cylinder. The parts of the curler are made of a plastic having sufficient resiliency to permit the

heads

28 and 30 to be forced through the collars, and after the heads are through the inturned flanges, out ward travel of the rods, knobs and clips is limited by engagement of the heads with the collars.

It will be seen that the cylinder 12 can also be called a roller 12 and the roller 12 and the knob 22 are relatively movable with respect to each other and can, therefore, together be called a relatively movable assembly made up of cylinder 12 and knob 22. The relatively movable assembly has a portion which is adjacent the flange or collar 32 at times when a

clip

16 or 18 is in the storage position, the said portion having a clip recess therein. The clip recess is identified in FIGURE 1 as that part of the opening 34 which extends through. the side wall of the cylinder 12. The clip recess is in communication with the opening in the flange 32 during clip storage. Each clip recess receives a portion of the

respective clip

16 or 18 during clip storage. In this way, a clip recess in a side wall cooperates with the opening 34 in the flange 32 to permit the knob to be moved inwardly more closely adjacent the cylinder 12 than the clip position might otherwise allow.

It will be seen that end of each

knob

20 or 22 which is disposed farthest from the roller or cylinder 12 has an outer surface of a shape at least sufficiently round as seen in cross section taken transverse to the elongation of the roller as to facilitate rapid rolling of the knob in an operators fingers to rotate the knob for the positioning of the respective clip.

It will be seen that cylinder 12 can also be called a hollow elongated roller having an outer side of substantially cylindrical shape. That part of the

knob

20 or 22 which extends inwardly of the respective flange 32 can be referred to as a concentric section on the inner face of the knob adapted to be received in the passageway defined by the annular flange 32. Each

head

28 or 30 is of such size and shape with respect to the passageway defined by its annular flange 32 as to maintain the respective head in the roller 12 during normal operation.

Operation In use the knobs are drawn outwardly until the ends of

spring clips

16 and 18 are in position to be inserted through the notches 34, and with the

rolled ends

40 and 42 extended through the notches the

knobs

20 and 22 are moved inwardly whereby the clips are positioned inside of the roller. The

clips

16 and 18 are resilient so that their outer portions are biased to move toward the central axis of the cylinder 14 and this facilitates the insertion of them into positions inwardly of the cylinder 12. This also causes the clips to press toward the outer side of the cylinder to firmly hold a hair roll, not shown, in place.

With the clips in the roller, hair is rolled around the cylinder 12 until the cylinder is against the head, and with the cylinder held in this position, the clips are drawn outwardly by the knobs until the rolled ends of the clips are in position to slide over the hair wrapped around the roller.

By this means the rollers with hair wrapped thereon are retained against the scalp as the hair is dried by air circulated through the rollers and hair thereon.

It will be seen that the length of each clip carrying member 35, and the length of that portion of the cylinder 12 in which the respective clip carrying member is at times disposed, are such as to permit the

free terminal ends

40 and 42, respectively, of the clips to be disposed toward the respective end of the cylinder, at which its

respective knob

20, or 22, is disposed, sufliciently so that the outer portion of the respective clip, including its

terminal end

40, or 42, is substantially out of the way of the tress of hair, yet preferably on the cylinder 12, and these lengths are such as to permit the

terminal ends

40 and 42, and the outer portions of the clips, to be then moved across the cylinder 12 axially of the latter, to respective positions alongside and substantially lapping the cylinder for holding a tress of hair (not shown) against the cylinder.

It will also be seen that the

heads

28 and 30 have their diameters disposed transversely of the cylinder 12, which diameter is greater than that of the central holes through the inturned flanges 32, whereby the

heads

28 and 30 and the inturned flanges 32 serve as a means for maintaining the inner ends of the respective clip carrying member 35 within the cylinder 12.

From the foregoing description, it is thought to be obvious that a hair curler constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
