The present invention relates to hair-dressing tools, and is more particularly directed toward hair-dressing tools having a mandrel slotted to receive a disappearing comb so that hair may be Wound about the mandrel to form a curl.

In hair-dressing tools of the type referred to the disappearing comb is adapted to be in an exposed position for combing the ends of the lock of hair and assisting in starting the winding of the curl, or to be housed in the mandrel so that the wound coil of hair may be readily removed from the mandrel.

The present invention contemplates the positioning of the disappearing comb within a slot of depth greater than the radius of the mandrel, and off center of the mandrel axis, thereby permitting the disposition of one of the Shanks of a bob pin within an axially aligned opening extending inwardly of the end of the mandrel.

Another object of the in'vention is to arrange the hair curling device so that when the hair securing member (preferably in the form of a disappearing comb insert) is in position to hold the hair during the winding operation, the bob pin is held on the mandrel against accidental removal and out of the winding zone defined by said hair securing member and so that only after completion of the winding operation and release of the hair is it possible to pass the bob pin along the mandrel to bring the exposed shank opposite the winding zone.

The present invention further contemplates the application of a bob pin, one of the Shanks of which is undulated in association with the mandrel of the hair-dressing tool, and provides Y for the support and engagement of such bob pin, an annular projection at the end of the mandrel in conjunction with the axial opening extending inwardly of the mandrel, such annular projection having undulations complementary to those on f the undulated shank of the bob pin, so as to permit the maintenance of the bob pin axially of the mandrel while at the same time it is distant from the tress winding zone of the mandrel, the rotation of the bob pin axially of the mandrel so that f' the bob pin may be in a position in line with the end of the curled tress and adjacent the scalp, and the spreading of the bob pin under tension as the same is urged inwardly and longitudinally along the mandrel at the desired position close to the end of the curl adjacent the scalp. The annulated formation of the mandrel is applicable to hair-dressing tools having hair holding means of the clamp type as well as to those with the disappearing comb type.

In order to reduce the weight of the device and its cost, as well as to facilitate molding operations, the mandrel is provided with a recess communicating with the hairpin receiving opening and extending outwardly through the side of the mandrel. This recess has an end wall to form a stop for the inserted shank of the hairpin.

The present invention also contemplates improved mechanism for controlling the movements of disappearing comb inserts. The devices employed include a small leaf spring and follower both carried in an opening extending transversely of the disappearing comb insert and adapted to cooperate with a cross member carried by the sheath.

Other and further objects will appear as the description proceeds.

The accompanying drawings show, for purposes of illustrating the present invention, two

of the many embodiments in which the invention i may take form, it being understood that the drawings are illustrative of the invention rather than limiting the same.

In these drawings:

Figures 1 and 2 are side elevational and top plan views of a hair-dressing tool with the disappearing comb insert exposed and the bob pin in initial position;

Figure 3 is an elevational View of the tool with the insertl sheathed and the bob pin completely inserted;

Figure 4 is an end elevational view;

Figures 5, 6 and 7 are sectional Views on the lines 5 5, 6 5 and '1 -l, respectively, of Figure 1;

Figures 8 and 9 are fragmentary views similar to Figures 1 and 3 showing a modified yform of construction; and

Figure l0 is a section on the line l iP-i ii of Figure 8.

The body member l of the hair-dressing tool is usually made in the form of a molded plastic article. It has a series of combing teeth II at one end and a mandrel I2 at the other end. This mandrel is generally cylindrical shape, but may, as shown in the drawings, taper slightly to stien the article and to facilitate removal of the hair wound around the mandrel.

The mandrel end of the tool is provided with a longitudinally extending slot i3 with widened portion ita near the outer end of the slot and adapted to receive a toothed insert or disappearing comb lll with a laterally extending element Ilia. This insert has two thumb pieces i 5, l5, the upper one extending out through the -a lower opening It.

ture 2| in the insert. This pin acts to keep the Y insert in place and to limit the extent of its movement. The insert is held in either extreme position by a follower 22, which may be notched or cut back at the ends, as indicated at 23, andl pressed against the pin by a small spring V2li. The spring and follower are received in the aperture 2l and are readily held in place when the device is completely assembled.

The mandrel end of the body member is provided with an axially extending hole adapted to rotatably receive the shank 26 of a bob pin 21. When the insert is exposed in the hair retaining position, as in Figures 1 and 2, the bob pin cannot be completely inserted because itis stopped by the laterally extending element lila formed on the insert opposite the opening 25 and in the path of the stright shank of the bob pin. The formation 28 at the mandrel end oi the body member is undulated to provide annnular ridge and'valley

formations

28 and 28", respectively. Such ridge and Valley formations are substantially complementary to the ridge and Valley formations 29 and 2t of the undulated shank 29 'of the bob pin 21, so that normally during the Winding operation of the tool the bob pin 21 may be maintained under tension axially of the mandrel and prevented from entering the zone on the mandrel where the hair tress is being wound. .After the hair is Wound the insert is depressed to enter the sheath, as shown in Figure 3 and in the dotted lines of Figure 5, therebyl moving the extension [da below the opening 25 so that when pressure is applied to the bob pin, the same isurged inwardly with its straight shank 2B being slid longitudinally within opening 25, and the undulated shank 29 being slid and under tension across the ridge and valley elements of the end formation 23 of the mandrel, the free portion of the undulated shank during such movement being spread sufficiently to pass overand be disposed adjacent the Wound tress or curl on the mandrel.

In addition, by virtue of the annular ridge and. valley formations 28' and 28" of projection 2S, the bob pin 2l may be rotated about its smooth shank 25 so that its undulated shank 29, having the ridge and valley formations, complementary to those of the end formation 28, may be disposed at any position radiallyrof the end formation and the mandrel, thereby permitting the subsequent clamping or grasping of the wound curl by the bob pin at a position close to the end of the curl and adjacent the scalp, as the bob pin is slid inwardly upon completion of the curl preparatory to release of the curl from the mandrel.

As shown in the drawings, the disappearing comb receiving slot is deeper than the radius of the mandrel and is placed to one side of the mandrel axis, so that the slotJ V2E for accommodating the smooth shank 21 of the bob pin may be formed in the axis of the mandrel. By this arrangement the bob pin will be mounted for 360 rotation about the mandrel axis, thus permitting application of the bob pin for clamping the end of the trees curl whe-rever it may be formed on the periphery of the mandrel. By virtue of this property the tress will be gripped by the bob pin as it is slid inwardly along the axis at the end of the curl formed on the man drel. While the material required to form the right-hand or front wall of the sheath is, as shown in Figure 6, thicker, yet it is possible to materially reduce the weight of the device and facilitate molding operations by providing recesses such as indicated at Se to The recess 3d extends beyond the mandrel axis and com-Y municates with the bob pin receiving slot 25. The web 35 between recesses te and 3l forms a stop for the end of the bob pin.

The body member is made of suitable plastic in a longitudinally split mold with a suitable blade for forming the comb receiving slot and pin for forming the bob pin receiving hole. The recesses 3E! and 3l extend inwardly as far as possible and are formed by core like elements provided on the inside of the half of the die employed for the front face of the molded article. This makes it possible to employ a short pin in the mold to produce the opening 25.

The annulated end, the side recess and axial hole arrangement may be employed in rod and clamp type curlers as well as in curlers of the disappearing comb type. The provision of a stop element such as the lug ida on the insert to control insertion of the bob pin is not con-v fined to hair-dressing tools of the type where the comb insert has no longitudinal movement, but can in its broader aspects generally be applied to other types of hair-dressing tools. It

may also be employed in hair-dressing toolsV without the annulated end.

In the arrangement shown in Figures 8, 9 and 10 the toothed insert Il!) has an extension H movable in a slot -152 and adapted to depress a spring 43 carried in a recess 4d. The end i5 of the spring has a hole 4B normally above the opening 25 in the mandrel, but adapted to be brought in line with it when the insert is in the inner position as shown in Figure 9. When the insert is exposed, as shown in Figure 8, the solid part of the spring 63 is opposite the opening 25 in the mandrel so that the bob pin shank is stopped.

It is obvious that the invention may be embodied in many forms and constructions within the scope of the claims and I wish it to be understood that the particular forms shown are but a few of the many forms. Various modications and changes being possible, I do not otherwise limit myself in any way with respect thereto.
