3.- Claims.

This invention relates generally to hair curling devices, and more particularly toa hair curler clamping bobbin of improved construction.

In the curling of hair, and particularly in the production of so-called permanent waves, the hair of. the user is wound upon some bobbin-like object and subjectedcto the action of heat, chemicals, or moisture, or combinations of these. In order to produce a desirable result, it is necessary that the hair. be. fixed in position while it is subjected to the waving treatment. Furthermore, it is necessary that a large number of individual locks of the users hair be wound.

It is therefore among, the principal objects of the present invention to provide novel and useful hair-curling clamping bobbins which are convenient to use being quicklymanipulatable. from an opento a closed position or vice versa.

Another object herein lies in the provision of a hair curler bobbin which maybe composed of relatively rigid material so that same does not become undesirably distorted in use.

Another object herein lies in the provision of structure of the-class described which islight in weight.

A feature of the invention lies in the absence of springs composed of metal which may lose their resiliency owing to heating and fatigue thereof and the absence of porous resilient parts composed of rubber orthe like which are deleteriously aiiected by heat or chemicals and which thereby lose their resiliency and low absorptive qualities.

Another object herein. lies in the provision of hair bobbin structure wherein the compressor latch element. utilizes. the resiliency of the coiled hair of the user for maintaining the same in a closed position.

A still further object liesin the provision of hair bobbin structure wherein the. range ofmovement of: the movable end plate may be amplified so as to accommodate a wider range of hair quantity treated by a single hair curling element, thereby enabling use of. the device by persons having. a relatively low degree of experience or skill in hair curling.

Another feature of the invention lies in the fact that the device may be formed almost entirely from non-metallic materials, such as synthetic resins of various types. Accordingly, substantially allpossibility of rust and other deleterious actions occurring are substantially eliminated.

These objects, as well as other incidental ends and advantages willmorei fully appear in the progressrof: this disclosure, and be pointed out in the appended claims.

In the drawing. similar reference. characters have been" employed to designate corresponding parts throughout the several views.

Figure 8' is aside elevational View of a second embodiment of the invention.

In accordance. with. the. invention, the hair curling clamping bobbin, generally indicated by reference character 10, includes broadly an axle element 1 I, a. meter stationary end plate It, a second or movable end plate 13,. and an expansive latch element. M. The various. parts may be made of anysuitable material, and I prefer to make'themof molded synthetic resin which is relatively stable in shape, substantially nonporous, substantially chemically inert with respect-to the waving solutions and materials used in the permanent. waving. operation, and which is. relatively light in; weight. The use of materials whichare. light in weight makes the present bobbin comfortable to. wear even when a large number of them are usedior a particular coiffure.

The. axle. element H is preferably generally rod-shaped, and includes aninner portion l5 and an outer; portion l6. The. inner portion is of substantially solid cross section, while the outer portion I6 is bifurcatedto form the legs 1! and I'Bhaving the slot is therebetween.

Thestationary end plate i2 is secured to the outer end of the inner portion IS in any suitable manner, or may be cast integral therewith as shown. The end plate 2 is preferably in the form of a disc having a periphery 2a.

Themovable end plate ['3 is preferably substantially identical with the stationary end plate 1.2, except that it is provided with a central orifice; .25 so: that it is slidable axially along the dwell portions 3| which respectively act against the inner surfaces 32 and 33 of the legs I! and I8. As may be seen on Figures 1 and 6, when the device is in a fully closed position, the dwell portions 3| extend across the entire width of the slot I9, thereby providing maximum spreading or expansive action. The latch element I4 is pivotally secured by means of a short pintle 7 member 34 which extend through both of the legs I! and [8.

The operation of my hair curler clamping bobbin is a simple and convenient matter. All of the necessary parts are so connected that one cannot be misled with respect to the others, and all can be grasped with a single hand. In operation the device is opened to take the position shown in Figures 2 and 3, and the hair of the user is wound about the axle element I l between the end plate l2 and the movable plate l3. After a particular lock of hair has been so jwound, the latch member 29 is grasped as a handle and is rotated in a clockwise direction as viewed in Figures 1 and 2. The inclined portions 30 of the cam surfaces 28 then come into action and serve to force the legs l1 and I8 apart, thereby exerting tension upon the inner periphery 35 of the movable plate I3. This tension serves to create sufficient friction to maintain the movable plate l3 in position, effectively preventing axial movement along the axle element H in either direction. The slot 19 extends a substantial distance from the open end thereof toward the end plate [2, a relatively wide degree of judgment with regard to the movable plate I 3 is possible. For example where the lock of hair to be wound about the axle element II is relatively thin or short, the movable plate 13 may be slid along the axle element ll toward the end plate l2, as required. Should the lock be relatively long or heavy, the plate I 3 may be moved toward the latch element l4. Simultaneously with the contacting of the dwell portions 3| against the inner surfaces 33, the surface 4| of the latch member 29 contacts the peripheries 2B and 26 of the end and movable plates l2 and I3. The parts of the device It] will now appear as shown in Figure l. The hair (not shown) now compactly wound may be subjected to any desirable waving treatment and where moisture or gases are given off. during the process, the same may escape both through the exposed surface thereof and through the slot l9. After the waving process is completed, the latching member 29 may be conveniently grasped and the element I4 is swung about the axis through the pintle member 34 to the starting position shown on Figure 2. The wedging or expansive effect of the cam surfaces 28 is then removed, and the movable plate [3 may he slid toward the pintle member 34 if necessary to assist in releasing the lock of hair.

Turning now to the second embodiment of the invention illustrated in Figure 8, for the purpose of avoiding needless repetition, parts corresponding to the first embodiment are given the same 4 reference characters, with the additional prefix I.

The second embodiment differs from the first embodiment principally in the wider range 'of movement afforded by the movable plate H3. The axle element is slotted more deeply, so that the dwell portions I3I may enter said slot even when the pintle I34 is positioned at the extreme right as seen on Figure 8 of the pintle engaging slots I50, that is to say at the end nearest the stationary end plate H2.

Thus by the provision of the slots I50, the fulcrum of the expansive latch element l M is made adjustable so that adequate expansion may be made upon the movable plate H3, where it is necessary to position the same at a point relatively close to the end plate H2. The resilient expansion of the legs H1 and H8 against the movable plate I I3, not only causes the latch element to stay closed, in a manner previously described, but also tends to maintain the pintle I34 in the particular position in which it has been placed.

While I have shown the slots l5!) as bein relatively short, any desired length may be substituted therefor to be used in producing a corresponding variation in the number of adjustments obtained.

It may thus be seen that I have invented novel and highly useful improvements in hair curling devices which are convenient to use, and may be quickly manipulated from an open to a closed position or vice versa. The devices may be manufactured at an extremely low cost, with consequent wide sale, distribution and use. The devices may be of extremely light weight, and of relatively foolproof operation.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art to Whic the present invention pertains.

I claim:

1. Hair curler clamping bobbin construction comprising: a first end plate; an axle element connected to said first end plate; a second end plate movable on said axle element with respect to said first end plate; said axle element including a bifurcated portion having first and second legs; a latch element including a cam portion which is of a size larger than the distance between said first and second legs when the same are in a relatively unstressed condition; said latch'element being pivotally mounted between said legs, and in one position thereof serving to expand said legs with respect to each other.
