Referring in detail to the drawings, the numeral 30 indicates the hair curler of the present invention which is shown to comprise a body 31 that is adapted to be made of a suitable material such as a suitable plastic ice material, and the body 31 has a hollow interior as at 32 and the hollow interior embodies or includes a first portion 33 of reduced diameter, a second portion 34 of greater diameter than the portion 33, and there is also provided a third portion 35 which is of greater diameter than the second portion 34, FIG. 1. The numeral 39 indicates a shoulder that is defined between and at the junction of the first and second portions 33 and 34. Similarly a shoulder 36 is defined at between the junction of the portions 34 and 35.

As shown in the drawings the body 31 has its outer contour or configuration of generally enlarged rounded formation as indicated by the numeral 37, and the outer contour of the body 31 also includes a portion 38 which is of a somewhat tapered reduced diameter as compared to the portion 37.

The numeral 40 indicates a small hollow roller which is xedly secured within the body 31 as, for example, by means of a pin 41, and the roller 40 has an end thereof projecting beyond the end of the body 31 for a purpose to be later described.

A cap 42 is mounted on the outer end of the roller 40.

-As shown in FIG. 5 for example there' is provided on the interior of the body 31 a plurality of spaced apart inwardly directed ribs 43 which define therebetween air spaces 44. As shown in FIG. 7 for example a channel member 45 is formed integral with or secured to the inner portion of the small roller 40, and the numeral 46 indicates a conventional electric heater element which is arranged in the channel member 45, and the heater element 46 is adapted to be connected to a suitable source of electrical energy as, for example, by means of a cord 47. As shown in FIG. 1 a portion of the cord 47 is adapted to extend through the portion 33 and the recess As shown in FIG. 5 for example, a medium diameter hollow' roller 48 is slidably mounted on the small roller 40, and the roller 48 is mounted for movement into and out of the third portion 35 of the recess 32. The numeral 49 indicates a large diameter roller which is slidably mounted on the medium roller 48, and the large roller -49 is also mounted for movement into and out of a re- 'of the button 51. The numeral 28 indicates an opening in the end of the body 31.

The :body 31 has an elongated slot 52 therein, and the numeral 53 indicates a manually operable slide button which is atiixed to the larger diameter roller 49, and the button 53 is mounted for travel through the slot 52 in the body 31.

The hair curler of the .present invention further includes a hair griper which is indicated generally by the numeral 54, and the hair gripper 54 includes an intermediate section 55 which is pivotally connected to the body 31 as, for example, by means of a pivot pin 56, and the hair griper 54 further includes an end section 57 which has a manually engageable button 58 suitably afxed thereto. The numeral 59 indicates a spring member which is interposed between the end section 57 and the body 31 for normally biasing or urging the hair gripper 54 in the proper direction. The hair gripper 54 further includes a section 60 which is of slightly arcuate formation as, for example, as shown in FIG. 16 and the section 60 defines or provides a jaw forselectively engaging one of the

rollers

40, 48 or 49 so that hair can be gripped beyterial such as Lucite.

tween the jaw and the proper roller in order to heat and curl the hair in the proper and desired manner.

From the foregoing, it will be seen that there has been provided a hair curler of the electrically operated type which is an improvement over prior electric hair curlers. When using the hair curler of the present invention the lady will plug the cord 47 into a suitable electrical outlet and after allowing suicient time for the heater element -46 to reach the proper operating temperature, the hair curler 30 of the present invention is ready for use. To use the hair curler the lady simply selects the roller size she desires and moves the rollers as, for example, by means of the

buttons

51 or 53. Then, the lady places a section of hair on the roller and the hair is held in .place by the hair gripper 54 and the hair is adapted to be rolled over the roller until the scalp is reached. A comb may be placed at the scalp to prevent the heat of the roller from burning. The lady will hold the rolled hair in place by the handle portion v38 of the body 31 for a predetermined lperiod of time and then the lady nee-d only slide the hair curler out of her hair so as to leave or provide a firm curl set.

The hair curler of the present invention will permit a ladys hair to be styled with increased efficiency and the hair curler of the present invention will produce a more efficient hair curler as, for example, as compared to the prior hair curlers which have been marketed or used. The present invention can be made and sold at a relatively low price and some of the advantages of the hair curler of the present invention over existing hair curlers are that all of the various size rollers are maintained heated at all times. Thus, by simply sliding the rollers in and out by means of the

buttons

51 or 53, the lady can select the proper heated curler instantly. With the presently marketed or used hair curlers, the lady must remove a hot roller from the curler and replace it with a cold (room temperature) roller and Wait two to five minutes for such roller to become hot enough to perform its job. Thus it will be seen that the present invention not only reduces the amount of work required but also permits lthe lady to set her curls more quickly.

The parts can be made of any suitable material and in different shapes or sizes as desired or required. For example the small roller 40 may have a diameter of three- -quarter inch, the medium roller 48 may have a diameter of seven-eighth inch, and the large roller 49 may have a diameter of one and one-eighth inches. The body 31 may be molded from a suitable plastic, and similarly the

slide buttons

51 and 53 may be made of plastic. The small roller 40 has the end cap 42 mounted thereon. The spring 59 serves to insure that the jaw 60 will maintain the proper pressure on the hair on the rollers, and by manually pressing on the button 58, the tension of the spring 59 can be overcome to open or move the jaw l60 -awayffrom the rollers as, for example, when the hair is being arranged in engagement with the rollers. The device is adapted to be attractively and esthetically made so thatit will have increased eye appeal, and suitable colors of an attractive or contrasting nature can be used for making the various parts where desired in order to further enhance or increase the attractiveness thereof, and the device is adapted 'to be conveniently -gripped in the hand of the lady or other person to permit proper and convenient use thereof.

The manually operable slide buttons are adapted to be knurled or roughened on their outer surface so as to facilitate manual engagement therewith, and these buttons as Well as the cap 42 may Ibe made of a suitable ma- The small roller 40 is adapted to be made from a suitable material such as aluminum extrusion, and similarly the medium and large rollers are also adapted to be made of a suitable heat conductive material such as aluminum. The end of the body 31 may have an aperture or opening therein for the insertion therethrough of the cord 47. As shown in FIGS. 8

and 9 for example, the body 31 has inwardly disposed spaced apart ribs which define or provide air spaces therebetween. The small roller 40 may have a wall thickness of .035 inch, and the roller 40 may have an outside diameter of .750 inch, but these dimensions are merely illustrative and can be varied as necessary. Instead of using the cord 47 for attachment to an outside source of electrical energy, the hair curler of the present invention may be provided with energy cells to supply electrical energy for the heater 46, or the device can be made so that at the option of the user, energy cells of the rechargeable type, or the electric cord can be selectively used.

It is to be noted that only the large and medium rollers are movable, and the small roller is fixed to the body, and the large and medium rollers are in sliding contact with the small roller so that after the unit is connected to a suitable source of electrical energy, the heater 46 will transfer the heat to the small roller 40 which will conduct the heat to the two

remaining rollers

48 and 49. The button 53 is affixed to the large roller 49 so that by manually moving the button 53, the large roller 49 can be moved to extended or retracted position. Similarly by manually moving the button 51, the medium roller 48 can be moved to extended or retracted position. FIG. 11 illustrates the hair curler with the small roller 40 being the only roller exposed, While FIG. 13 illustrates the medium roller 48 exposed, and FIG. 15 illustrates the large roller 49 exposed.

As shown in the drawings the large roller is in sliding contact with the middle roller so that there is no play or wobble in the large roller. As shown in the lower portions of FIGS. 3 through 7, the

rollers

49, 48 and 40 are in tangential contact at all times so that the heat transfer can take place. It is essential that the rollers be in sliding contact with one another for the conduction of heat through all the rollers.

With the present invention the lady does not have to Wait for the individual rollers to become heated to the proper temperature as in the prior devices, and also in the prior hair curlers it is necessary to manually handle the hot rollers as, for example, when the rollers are being removed from the hair curler and since these rollers are hot, this is a disadvantage which is overcome by the present invention wherein it is not necessary to manually touch the rollers since the

slide buttons

51 and 53 can be moved to position the rollers Where desired or required. Also with the present invention the different sizes of rollers are simultaneously heated so that it is not necessary wait as, for example, when different rollers are being used whereas with the prior art devices since the roll-ers are actually completely separated or removed from the hair curler, it is necessary to wait several minutes for the rollers to become heated to the proper temperature before the device can be used. When moving out or extending the large roller 49 by means of the but-ton 53, the medium roller 48 is likewise moved out to extend the position so as to insure that there Will be proper contact and heat transfer between all of the rollers. The air spaces such as the spaces 44 between the ribs within the body provide insulation so that the device will not get too hot when being used. Also, due to the provision of the ribs 43, it will be seen that the only points of contact between the heated roller 49 and the body will be through the ribs or at the ribs 43 and this will also help minimize or prevent the body from becoming overheated.

With the present invention the art of hair styling can be improved and simplified and a wide variety of coiffures canbe eiciently effected or accomplished.

The number of rollers can be varied as desired, and the plastic body 31 is adapted to hold the different diameter rollers. The smaller roller contains the heater element, and the smaller roller is permanently affixed in the plastic body while the other rollers are slidable relative to the stationary roller 40. In order to conduct the heat from the heater 46 inside the small diameter long roller 40 to the other two rollers, all of the rollers are in contact at one point as shown in the lower portion of FIGS. 3 through 7 so that in effect the rollers are arranged as eccentric circles tangent at one point, and the point of tangency is suicient contact to conduct heat through the length of all the rollers. Thus, when the two larger rollers slide over one another and the small diameter roller, heat is conducted therethrough regardless of the position of the larger rollers on the small diameter roller.

Although the invention has been herein shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and .all equivalent devices and apparatus.
