Application March 29, 1957, Serial No. 649,535 Claims. cl. 132-34 My invention relates to devices for curling hair, and one of its objects is to facilitate the quick formation of neat curls.

Other. objects are to secure the shape of each curl before it isremovedfrom the curler by one or several hair pins, toeject each pin froma container incorporated in the device, thereby to make unnecessary the handling of hair pins during the curling operation, to apply each pin to the curl in a direction crossing the axis of the curl, and thereby to-make possible to secure each curl in a position in which the curl is near and parallel to the scalp.

Further-objects are to spread each pin temporarily while it is applied tov the curl, thereby to grip the curl from both flat sides, and thereby to avoid that some hairs of the curl remain loose outside of the pin.

,Still other objects are to provide simple and stationary means for spreading the pins, to provide the opening Fig. 5 shows a cross-section taken along the line 5-5 in Fig. 1.

Fig. .6 shows a perspective view of a broken off part of the same embodiment. i

Fig. 7 shows a perspective view of a hair pin and of a broken off push member to be used inthe same embodiment.

Figs. 6and 7 are represented on a much larger scale than Figs. 1 to 5.

The shown embodiment has a frame or housing which comprises parts 6, 7 and 8. The part 6 may form a rectangular box. The parts 7 and 8 extend from this box in that direction which during the operation, points to the scalp of the person whose hair is being curled.

The part 7 forms a tube terminating in a ring9. The

part 8 forms a container for hair pins as will be described later.

which a continuation 14 forming a shaft of square crosssection extends toward and through the box. 6. This part 14 engages slidably the square bore of gear element 15 which is rotatable in bores of the box 6 and, in the shown condition extends a shortway into the part 7. A spring 16 is positioned between a shoulder of the through which the pins are ejected with projections which forcethepin legs into spreading position, and to shape this opening and the pins so that the pins can pass the opening entirely despite these projections and snap into non-spread condition after most of the pin has been ejected.

Still'other objects are to provide a rotatable curling core which can be partly shifted into a housing whereby a'curl formed about this core is shifted,-gathered:and collected on it into a neat and narrow shape in which it can be easily gripped by an ejected pin, andto provide the core portion which receives the so shifted, gathered and collected curl with longitudinal slots that allow passage of the pin and withdrawal of the device from the secured curl. 1

Still other objects are to operate the deviceby a handle, to derive rotation of the curling core and ejection of the pins from the movement of one handle, to make possible the choice between different curling direction without change in the position of the device relatively to the scalp, to keep the curling, core stationary while pins are ejected,and to operate -the;ejectionof pins only when curls are not being formed by rotation ofthe core. I

Still further objects are to attain these results with simple and inexpensive means and to provide a hair non-section ally.

Fig. 2 shows a view of the same embodiment seen i from the right side in Fig. 1. v v Fig. .3 shows a cross-section taken along the line 3-3 in Fig. 1. p v I Fig. 4 shows a detail seen from the lower side in element 15 and a wall of the box 6 and urges the element into the shown position. A spring 17 is positioned in the part 7 between the box 6 and the core 11 and urges the latter into-the shown position in which a stop 18 aflixed to the end of shaft 14 contacts the box 6.

A handle 19 passes slidably through a slot of the.

lower wall of box 6. The lower end of thi's'handle is bent to form a projection 21. The box 6 has a parallel projection 22. The hair curler may be 'held by two fingers, one under the projection 21 and the other over the projection 22 and may be operated by alternately compressing and spacing these fingers. .7

Two racks 23 form a forked extension of the handle 19 and extend in the box 6 and slidably through slots in its upper wall. A spring 24 is hooked to one of these racks and to the bottom of the box 6 and urges the handle with its forked extension back into the shown position when the handle has been moved upward.

'One of the racks 23 engages a pinion 25 which may form 'an integral part of a transmission element that further comprises a toothed wheel 26 and an axle 27. This axle is rotatable in slots 28 of a little frame 29 which passes slidably through lateral slots of the box .6.- .When this frame is shifted horizontally, the pinion 25' is disengaged from one rack and brought into engagement with the other rack whereby the rotary direction of the pinion is reversed.

When the handle is moved upward, the engaging rack pushes the pinion 25 and the wheel 26 upward until the axle 27 reaches the upper ends of the slots 28. In this raised position, the wheel 26 engages a pinion31 which is a part of the element 15. whereby rotation in the one or the other direction is transmitted to the shaft 14 and to the core 11. i 1

The housing part 8 has a top wall 32, a bottom wall 33 and a vertical wall 34, which comprises a half cylinder open at one side for the insertion of a member 35. This member has a solid portion 36 connecting an inner v cylindrical wall 37 with a less high cylindrical outer wall 38, and has a bottom 39 whereby a deep arc-shaped groove 41 is formed. A slot 42 extends along the bottom of this groove. The bottom 39 has further a central bore for the passage of a shaft 43. After the member 35 has been placed, this shaft is inserted in this bore and in a concentrical bore of the top wall 32 and is secured to the housing by a pin 44. The member 35 is rotatable about the shaft 43 and forms, together with walls of the housing part 8, a container or magazine for hair pins. I

Figs. 1 and 3 show this container empty for the sake of its clearer representation. But it should be understood that a number of hair pins 45 (see Fig. 7) are filled into the member 35 before it is placed into the part 8. These hair pins are so positioned that their heads are in the groove 41, their legs point toward the top wall 32 and one leg is adjacent to the cylinder wall 37.

The bottom 33 has a circular opening through which a pin 46 reaches which is aifixed to the member 35. The lower end of the shaft 43 reaches also through this opening. A spring 47 connects this shaft end with the pin 46 and is so wound and tensed that this spring urges the member 35 to turn in the direction of the arrow 48 in Fig. 3. Thereby the hair pins in this member are pushed in the direction of the groove 41 until the foremost hair pin contacts a wall 49 which extends from the housing wall 34 inward into the space over the groove 41.

The wall 49 is so positioned that this foremost hair pin is positioned near the end of the housing part 8 which is farthest from the box 6. In line with and over this hair pin, the top wall 32 has an opening 51 for the ejection of hair pins. The direction of this opening crosses the rotary axis of the core 11 preferably directly or at small distance and passes near and outside of the ring 9.

The details of the opening 51 are shown in Fig. 6. Seen from the upper or outer side, this opening is shaped like the letter I, the narrow stem of this I being formed by two projections 52 extending from opposite walls of the opening 51. The broader top and bottom of the I are each large enough for the passage of one hair pin leg. The vertical cross-sections of the projections 52 are broadest at the outside and taper toward the inside whereby the projections form wedges which spread a hair pin pushed through the opening more and more until the broader leg ends 53 have passed through. The remaining head end 54 of the hair pin is narrower than the ends 53 and not broader than the narrow I stem of the opening whereby the hair pin snaps back into closed condition as soon as the broader ends 53 are out of the opening. Further push drives the remaining portion 54 out of the opening.

For pushing or ejecting the hair pin, a member 55 is provided which may be a cylindrical stem having a narrowed upper end 56 fitting the narrow portion of the opening 51. The stem 55 is guided in a lower tubular extension 57 of the housing part 8. The lower end of the member 55 is aflixed to one end of the movable core 58 of a flexible transmission element 59 of the well known type which is used, for example, for operating the shutter of a camera. affixed to another stem 61 which is guided in a tubular lower extension 62 of the box 6. The flexible element 59 (shown broken off in Figs. 1 and ).connects the lower ends of the tubes 57 and 62 and is so arranged that its known inner spring action urges the stem 61 up into the box 6 and withdraws the stem 55 from the inner space of the hair pin container. When the stem 61 is pushed down, the stem 55 moves up through the slot 42 of the bottom 39 in the direction toward the opening 51.

An angularly bent spring 63 has an obliquely vertically extending portion affixed to the stem 61 near the upper end of the latter and has an about horizontally extending portion overlying this stern partially. A projection 64 is 64 is released and the stem 61 returns automatically in its upper original position.

With the described device, curls may be made in the following manner:

The end of a strand of hair is attached to the curling core 11 by wedging this strand end between the core and a resilient clamp 66 aflixed to this core. The device is so held that the axis ofthe core 11 points toward the scalp, and the handle is moved into the box 6 whereby the core 11 is rotated and the strand is wound about the same. If continued rotation is desired, the handle may be reciprocated several times without being pushed inward quite as far as possible whereby the catch 63, 64 will not engage.

Then, the core 11 is shifted into the tube 7 whereby the ring 9 shifts the curl from the clamp 66 to the slotted portion of the core 11. This shift brings the hairs of the curl closer together in axial direction and gives the curl a neat fiat circular shape. The curling core moves inward until its stem contacts the box 6. During the last stretch of this way, the member 15 is shifted a little farther against the spring 16 whereby the pinion 31 is moved out of line with the wheel 26. The tube 7 has one or more inner grooves 67, each adapted to receive the clamp 66 catches the spring 63. Hence, the downward returning The other end of the core 58 is rack 23 takes the stem 61 with itself down. The curling core remains stationary in a position secured by the clamp 66 in the groove 67. In this position, a slot of the curling core lies over the opening 51.

The downward moving stem 61 forces the stem 55 to move upward into the position indicated in dotted lines in Figs. 1 and 3 whereby the stem 55 pushes the hair pin which is adjacent to the wall 49 through the opening 51 and through the slotted portion of the curling core. During this movement, this hair pin is spread in the manner described before and returns into closed condition while gripping the curl from both flat sides.

As soon as the pin 65 disengages the spring 63 from the projection 64, the stems 61 and 55 return to their original positions. The stem 55, withdrawn from the hair pin container, makes the way free for another hair pin to move into contact with the wall 49 under the urge resulting from the spring 47.

After the curl has been secured by the application of one or more hair pins, the device is withdrawn from the scalp whereby the curl with the securing pins slips from the curling core. The curling core returns automatically to its original position, and the device is ready for the making of another curl.

I desire it understood that my invention is not confined to the particular embodiment shown and described, the same being merely illustrative, and that my invention may be carried out in other ways within the scope of the appended claims without departing from the spirit of my invention as it is obvious that the particular embodiment so aflixed to one of the racks 23 that, when the handle shown and described is only one of the many that may be employed to attain the objects of my invention.
