5 Claims.

This invention relates'generally to hair curling devices, and more particularly to a hair curler clamping bobbin of improved constructiorn In the curling of hair, and particularly in the production of so-called permanent waves, the hair of the user is wound upon some bobbinlike object and subjected to 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 locksof the users hair be wound.

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

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

Another object herein lies in the provision of structure of the class described which is light in weight.

A still further object herein lies in the provision of means for the escapement of moisture or fumes produced in the hair coils during the Waving treatment.

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 or the like which are deleteriously affected by heat or chemicals and which thereby lose their resiliency and low absorbent 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 lies in the provision of hair bobbin structure wherein the range of movement of the movable end plate may be amplied 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.

These objects and other incidental ends and advantages will more fully appear in the progress of this disclosure and be pointed out in the appended claims.

In the drawings in which similar refer- 2 ence characters designate corresponding parts throughout the several views:

Fig. 1 is an elevational view of a hair curler clamping bobbin showing an embodiment of the invention in a closed position thereof.

Fig. 2 is an end elevational View as seen from the plane 2-2 on Fig. 1.

Fig. 3 is a plan view seen from the plane 3-3 on Fig. 1.

Fig. 4 is an elevational view corresponding generally to Fig. 1, but on a reduced scale and showing the device in an open position thereof.

Fig. 5 is an enlarged fragmentary horizontal sectional view, partly in elevation, as seen from the plane 5-5 on Fig. 1.

Fig. 6 is a view in perspective of the embodiment shown in Fig. 1.

Figs. 7, 8 and 9 are an elevational view, a perspective View, and a sectional View (plane 9-9 on Fig. '7) respectively, of a second embodiment of the invention; while Figs. 10, l1 and 12 are an open elevation, a closed elevation (reduced), and an end view, respectively, of a third embodiment, whose axle element is shown in detail elevation in Figure 13.

In accordance with the invention, the hair curler clamping bobbin, generally indicated by reference character l0, includes broadly an axle element Il, a rst or stationary end plate l2, a second or movable end plate I3, and a compressor latch element I4. The various parts may be made of any suitable material, and I prefer to make them of molded synthetic resin which is relatively stable in shape, substantially non-porous, 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 o1" materials which are light in weight make the4 present bobbing comfortable to wear even when a large number of them are used for a particular coilure.

The axle element is preferably generally rod shaped and includes an inner portion i5 and an outer portion I6. The inner portion is of greater diameter than the outer portion. The outer portion l5 is bifurcated to form the legs Il .and

i8 having the slot i9 therebetween.

The stationary end plate I2 is secured to the outer end of the inner portion l5 in any suitable manner or may be cast integral therewith as shown. The end plate l2 is preferably in the form of a disc having a periphery 20 and a plurality of venting orices 2|.

The inner portion l5 has a

hollow bore

22,

and 272 extending off the slot passageway 273, instead of in the axle element.

The axle element 2II may be a form of split rivet which is provided with a reduced portion 27@ upon which the relatively statonary end plate 2 I 2 is mounted. The head 2'I5 when peened over also supports the retainer element 279 having the two

end hooks

277 and 278. These hooks may be used to engage adjoining or adjacent hair strands to retain the device 2i in position upon the users head, with the plate 2I2 toward the scalp. In order to permit the latch member 229 to close when the

notches

279 or 27! are engaged by the pin 236, the hook 277 may be provided with an indentation 272, or the retainer element may be rotatably mounted with some friction in the joint. It may then be rotated as indicated for example by the dot-dash lines on Figure 12.

As seen in Figures and 1l, the latch element 2 Iii is in the form of a lever having an edge cam surface 223 and a latch member 229. The cam surface 228 may include a low dwell portion 232, a rise 233, and a high dwell portion 234. The operative elf-ect of these parts will vary, depending upon which notch of the

notches

270, 27| and 272 has been selected by the user, as the axis or rotation of the latch element 2M. Since each of the notches extends obliquely toward the

cam portions

233 and 234, the resilient pressure of the users hair presses the movable plate 2I3 against the portion 234, which tends to move the latch element 2 I4 in a direction axially of the axle element 2i I and away from the stationary plate 2 I2. This tends to retain the pin in the closed end of the particular notch in which it is then located. All this causes the latch member 229 to be moved toward engagement with the peripheries of the end plates 2 I2 and 253.

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.

I claim:

1. Hair curler clamping bobbin construction comprising: a rst end plate; and an axle element connected to said rst end plate; a second end plate movable on said axle element; a cam engageable with said second end plate and acting to move the second end plate toward the first end plate; said cam being detachably pivotally mounted upon said axle element at a plurality of locations on said cam.

2. Hair curler clamping bobbin construction comprising: a rst end plate; an axle element secured to said first end plate, said axle element having a pivot; a second end plate movable on said axle element; and means to move the second end plate toward the first end p-late, said means including a cam having a plurality of notches selectively engaged with said pivot.

3. A structure as claimed in claim 2 with a retainer element on the first end plate.

4. A hair curler clamping bobbin comprising: a first end plate having a first periphery; a second end plate having a second periphery; means movably connecting said rst and second end plates; a compressor latching element pivotally mounted on said means and contacting a portion of said second end plate, movement of said latching element acting to shift the position of said second end plate with respect to said first end plate; said compressor latching element having a latching member which contacts said first and second peripheres when said bobbin is in closed position thereof.

5. A hair curler clamping bobbin comprising: arst end plate having a first periphery; a second end plate having a second periphery; an axle element movably connecting said first and second end plates; a compressor latching element pivotally mounted on said axle element and contacting a portion of said second end plate, movement of said latching element acting to shift the position of said second end plate with respect to said first end plate; said compressor latch element including a cam surface actuated by movement of a latch member; said last mentioned latch member contacting said rst and second peripheries when the bobbin is in a closed position thereof.
