Patented June 16, 1942 UNITED TES PATNT OFFI 4 Claims.

My invention relates to hair curlers and more particularly to the type of hand operated curlers which are designed to form a curl and support a hair pin for the purpose of grasping said curl and maintaining its formation.

As far as I am aware, the efucient hair curlers now known are constructed so as to necessitate the following steps:

A. Positioning a hair pin on the curler subsequent actuation.

B. Applying the curler to the hair so as to grasp a strand thereof.

0. Forming the curl:

D. Actuating either the formed curl or the hair pin so as to effect the union between the two:

E. Releasing the grasp of the curler on the hair strand and F. Holding the curl and hair pin with one hand while withdrawing the curler with the other.

This procedure forms one curl. It is repeated to form others.

While the method outlined is not unduly involved it must be noted that the action most often takes place at the rear of the headwhere the user does not have visual access and that the operation therefor presents practical difficulties.

It is the principal object of the present invention to simplify the procedure to such anextent that most of the steps hereinabove outlined are either eliminated or at least automatically accomplished by a single motion.

Another object of my invention is to provide a curler which carries its own hairpin supply in a convenient, simple and efficient magazine so that a pin'may be fed from said magazine to the formed curl.

Another object of my invention is to provide a curler wherein the usual mandrel about which the hair is wound embodies means to reduce the thickness of such mandrel when the curl is completed so that the combined curl and pin may easily be slid ofi the end of the mandrel.

Another object of my invention is to provide novel and automatic means for releasing the grasp of the curler on the formed curl, this purpose being accomplished without the necessity of actuating the clip initially used to connect the curler to the hair strand.

A further object of my invention is to provide a curler of such construction as to simultaneously and automatically supply a hair pin to a formed curl, reduce the effective thickness of the mandrel for the purpose herein above set forth, and release the grasp of the curler on the hair for strand, the above steps being accomplished by one simple movement.

It is also an object of the present invention to effect all of the above results with a simplified construction of the device itself so that manufacturing costs are decreased and economies realized,

Other objects of my invention will be apparent from the following description it being understood that the above general statements of the objects of my invention is intended to explain and not to limit it in any manner.

In the drawings, I represents the mandrel about which the hair strand H is Wound, the mandrel. 1 comprising the mandrel jaws la and lb. The jaw lb is connected as by solder to the plug 2 while the jaw I a is movable in respect to the housing 3v and is connected to the jaw lb by the spring 4. Thespring 4 has its ends connected to the respective inner faces of the mandrel jaws.

A pivot Ic movably connects the inner end of the movable jaw Ia to the tubular member 9. The mandrel jaw la is further provided with a protuberance Id for a purpose to be hereinafter described.

The tubular member 9 is a hollow cylindrical 7 vided with an integral flanged sleeve I and a partial boss 8.

The housing 3 encloses the parts hereinabove described and is secured by the bolt 3a to the flanged portion of sleeve 1. Clamp 5 is pivotally connected to the inner wall of the housing 3 as by the hinge 62) formed from cars depending from said inner wall, and clamp 5 is actuated by the fingerpiece 8. The clamp 5 is normally urged into engaging position with the movable jaw Ia by means of the spring 6a which is connected at one end to the tubular member 9 and which communicates with the flngerpiece 6 through an opening in the housing 3.

The housing 3, tubular member 9 and sleeve I are all formed with an intercommunicating slot I2 which slot functions as the ejection chamber for the hairpins B.

The hairpins B are disposed around the tubular member 9 and their shanks have their free ends located on either side of the sleeve I, while the closed ends thereof abut the boss 8. Since the hairpins comprise shanks which in the normal clamping position abut each other, the sleeve 1 functions as a support for the hairpins also serving to maintain them properly alined.

A spring actuated follower I is disposed around and rotatably supported by the tubular member 9. Said follower I9 is formed with a flange II which, in response to the spring I5, bears against the hairpin supply and is designed to urge the foremost hairpin into the ejection chamber or slot I2. The flange Ii has a slotted end III), the sleeve I loosely fitting on said slot.

The follower I0 is further provided with a slot to accommodate the boss 8 of the tubular member 9 as seen in Fig. 8. The boss 8 extends from the slot I2 on the member 9, or just enough to accommodate the hair pin supply.

As shown in Fig. 1, the follower I3 is formed with a closed end I I (1. having two openings formed therethrough.' A cap I4 is rotatably connected to the plug 2 by means of the bolt I8, and pins I'I, entering the two openings formed in the closed end of the follower Ill, secure said follower II] to the knurled cap I4 so that both the cap I4 and the follower IIl may rotate relative to the plug 2 as well as the remainder of the device.

The cap I l and follower II] are connected by the spring I to the housing 3, the pin Ila, of the cap I4 operating as one terminal of the spring I5 and the end wall 16a of the housing 3 operating as the other terminal by abutting the end It of said spring.

A slide I3a having the fingerpiece I3 is located in the slot I2 and is slidably retained therein. The slide I3a operates from the normal position wherein it abuts the closed end of the follower I0 shown in Fig. l, to the extended position wherein the hairpin has been totally ejected, shown in Fig. 2. The slide I3a is further formed with a concave actuating end I31) and an inelined cam edge I30 for a purpose to be hereinafter described.

Secured to the rounded wall of the tubular member 9 is the floor I9 which supports thereon the hairpin spreader I911. The spreader I So comprises a single piece of twisted spring blade stock and is connected at one end 2| to the floor I9 while the other end is bent to provide the raised end 20. The end 20 of the spreader I9a is free and is further provided with an inclined edge 2%.

My invention operates in the following manner:

The hairpins B, as shown in Fig. 5, are inserted into the housing 3 through the slot 22, the shanks of the hairpins embracing the sleeve 7. While the supply of hairpins is being thus inserted around the tubular member 9, the knurled cap I4 is turned and held against the action of the spring I5 so that flange II of the follower I ll does not act against the hairpins and interfere with the loading of the magazine.

When all the hairpins have been inserted the cap I4 is released and the flange I I driven by the spring I5, bears against the adjacent or last hairpin in the magazine so that the foremost hairpin is forced into the slot I2. The wall of the slot I2 in the housing 3 adjacent the spreader I9a is formed with a flange 3d to function as a stop for the hairpins so as to insure the proper positioning of the hairpin in the slot I2. Furthermore, since the sleeve I is formed with a slot, comprising the slot I2, when the foremost hairpin has been urged into the slot I2 by the action of the flange II], the shank ends of the hairpin are shifted to a position wherein said shank ends embrace the spreader I9a as seen in Fig. 9. Thus the hairpin is wholly disposed in the slot I2 and supported at its shank ends by the spreader Illa.

At this point, the curler is ready for use and theflngerpiece 6 is depressed to admit a hair strand and grasp the same by the clamp 5. The entire device is now rotated so that a curl of hair H, as seen in Fig. 1 is formed around the mandrel I. When this curl has been completed, the slide I311 is actuated by the operators finger and the following action results:

The concave edge I3b of the slider I3a bears against the closed end of the hairpin and forces the same along the slot I2. Traveling, as the shanks do over the bent portion 20a of the spreader Isa, they are diverged as they emerge at the inner end of the slot I2. The lower shank travels under the cut-away portion 5a of the clamp 5 so as to slide under the formed curl H while the upper shank being spread embraces the periphery of the curl. This action is shown in Fig. 10 and Fig. 2.

When the closed end of the hairpin reaches the inclined edge 2% of the spreader I9a, it forces the spreader I9a downwards or laterally of the device. The spreader, being of spring stock, the central portion thereof functions as a spring'between the connecting end 2| and the free spreading end 20.

This lateral displacement of the spreader I9a clears the slot I2 so that the hairpin can wholly emerge from the housing 3. This action is illustrated in Fig. 10 wherein the hairpin B is shown in longitudinal section to reveal the disposition of the lower shank thereof.

When the slide I3a approaches the limit of its travel, the inclined edge I30 thereof bears against the protuberance Id of the movable jaw Ia of the mandrel I. This pressure depresses the movable jaw Ia against the action of the spring 4. As a result thereof, the clamp 5, which has remained stationary in relation to the housing 3 and the fixed mandrel jaw lb, is now spaced from the, mandrel so that the curl of hair H is automatically released from the grasp of the clamp 5, and the reduced diameter of the mandrel enables the device to be withdrawn without disturbing'the formation of the curl. In Fig. 2, R denotes the decreased thickness of the mandrel I permitting the release of the formed and pinned curl so that the device may be easily withdrawn for the'n'ext operation.

It will be noted that the radial construction of the magazine permits the rotation of the entire device in forming the curl and provides a most simple yet eifective mechanism. It will be jiurther noted that the simple movement in operating the slide l3a achieves the following results:

The hairpin is actuated to clamp the formed curl, the effective thickness or diameter of the mandrel is reduced to permit unrestricted withdrawal and the release of the clamp 5 is automatically accomplished.

When the slide 13a is in the position shown in Fig. 2, the succeeding hairpin will not be urged into the slot I2 by the follower I!) because the shank ends abut against the slide 13a and the spring I5 is too weak to overcome this resistance. This impediment at the free ends of the hairpin serve to keep the closed end thereof clear of the slot until the slide is retracted to its normal position whereupon, the passage being clear, the succeeding hairpin will be urged into the slot I2 and the operations may be repeated on another hair strand.

I have shown a preferred embodiment of my invention but it is obvious that numerous and very substantial changes may be made without departing from its spirit.

I claim:

1. A hair curling device comprising a hollow handle portion, a mandrel around which hair is adapted to be wound supported by and laterally of said handle portion, a sleeve located within said handle portion, a supply of hair pins radially disposed around said sleeve the shanks of said hair pins embracing said sleeve so as to travel thereabout and a slide adapted to individually actuate said hair pins from within said handle portion to a position of engagement with a curl formed around said mandrel.

2. A hair curling device according to claim 1 including spring means and a follower actuated by said spring means, said follower being concentrically disposed in relation to said sleeve and bearing against said hair pin supply whereby said hair pins are urged by said follower into a position to be operated against by said slide.

3. A hair curling device comprising a handle portion adapted to maintain a hair pin in position for ejectment, a mandrel supported by and laterally of said handle portion, and a spreader for spreading apart the shanks of the hair pin when ejected whereby said hair pin may engage a curl formed on said mandrel, said spreader being adapted to be laterally displaceable in respect to said device by the pressure of the closed end of said hair pin.

4. A hair curling device according to claim 3 wherein said spreader comprises an arm, spring means urging said arm into the path of movement of said hair pin during ejection, said arm being adapted to be laterally displaced against the action of the spring means by the pressure thereagainst of the closed end of the hair pin near the end of the ejection movement.
