Application August 26, 1950, 'Serial No. 181,664

This invention relates to a hair curling device, and in particular to one in which the curler is mechanically rotated. I

An object of this invention is to provideea new and `improved means of rotating the hair curler for the purpose of winding a tress of hair-thereon.

Another object is to provide a hair curler which is -easily detached from the curling device-after a-tress of hair has been wound thereon and which when. detached will not further rotate.

A further object is to provide a hair curling device which is light, compact, inexpensive and durable.

Other objects and advantages will become apparent from an examination of the drawings together with the description thereof wherein:

Figure 1 is an exploded perspective view of the winding device with a curling spindle separated therefrom, as just prior` toattachment thereto.

Fig. 2 is a vertical section, taken on line 2 2 of Fig. 1, showing the curling spindle attached;

Fig. 3 is a vertical section, taken on line 3-3 of'Fig. 2; and 'f Fig. 4 is a vertical section, taken on line 4 4 of Fig. 2.

As shown, kthe hair curling device of our invention makes use of a horizontally disposed frame or housing H having a hollow telescoping handle comprising an inner xedmember I andan outer movable member I2 depending therefrom. The handle member i0 is xed to the housing Hand the other handle member I2 is pivotally attached to the handle IG near its upper end by a pivot pin I4. A rotatable shaft I6 is journaled for rotation within bearings at opposite ends of the housing H, the shaft ends I8 and Illa, being extended outwardly therebeyond. A lug 2d having two arms is secured fast to the shaft near one end thereof so as to rotate therewith. A drum 22 having an associated ratchet 24 is mounted freely on the shaft I6 toward its other end, Vand a coil spring 25, having one end secured Yto an ear 28 on the ratchet 2li and its other end secured to the lug 2Q, encircles the shaft I6 at an intermediate point. A spring pawlS which engages the teeth of the ratchet 2d insures that the drum 22 will turn in one direction only.

Extending upwardly from and fastened to the lower end of the handle Illis a coil, spring 32. A flexible cord 3d which attaches to the free end of the spring extends upwardly therefrom and thence around the drum 22 through several turns from whence it leads downwardly to one'arm 36 of a bell crank 38 which is pivotally secured to the handle Iby a pivot pin 4D. A spring 42 normally holds the bell crank 38 in the position shown in Fig. 2 with the arm 36 against a stop M.' Just below the housing I-I, and extending partially outwardly through a slot in the handle I2, is a trigger 46 which is pivotally hung on the pin I4. A spring 50 presses the lower part of `the 6 Claims. (Gl. 132-34) 2 trigger outwardly lin which position the upper trigger .portion extends 4upwardly into the rotatableV path of lthe karms of the lug 293, as shown in Fig. 2. The movable handle member I2 is provided with a cam face 52 on its inner face which slidingly engages the outer arm 54 of the bell crank.

Extending .outwardly from opposite ends of the housing H and parallel to the shaft I6 is a guide rod 56.. AA hair curler, preferably made of alight plastic material and'comprising a bar 58 having'at one end a resilient offset split collar 6l] and a spindle 'S2 embraced at one end by the collar @60, is mountedendwise on the exteriorl of the housing H with Ythe shaft end I8 (or Ia) projecting into ,an axialopening 64 of corresponding size in the spindle end and the guide rod 55 snugly extending into a similar opening 66 formed in the ysplit in the collar 60. Ears SS and .58ct are extended radially from the Shaft near its `ends I8 and -I8a,v respectively. The ears 88a (or l5.23) project into lan oppositely disposed pair Vofslots 59 extending-from the spindle opening 64 at its collarend, as shown in Fig. 2, to pre-` vent rotation therebetween. When the curler is attached'to the housing as above described, the guide rod 55 Venlarges the split 65 slightly, and in so doing acts as a wedge therefor. This enlarges the collar 6G, causing v it to release its hold on the spindle 62 thus leaving it free'to rotate within the collar. V

In operation the device works as follows: First of all the nuser grasps the instrument in one hand, as when holding a pistol, and squeezes the handle members together. When the handle members are depressed toward each other, the cam face 52 on the handle member I2 presses the bell crank arm 54 inwardly to cause the arm 36 to lpull the attached cord endy Sil downwardly. This causes the drum 22 torrotate which in turn winds the spring 26. When the handle member I2 is released it vswings outwardly away from the member I0 in response to pressure from the bell crank spring 42. The shaft spring 26 is prevented from uncoiling by the spring pawl 30 at one end and an arm of the lug 20 at its other end which, in turn, is prevented from rotating by vthe trigger 46. The bell crank 38 reverts to its former vposition. (Fig. 2) which allows the cord 34 ytoslip back around the drum in response to pull `from the spring 32.

After the handle members have been squeezed together several times the shaft spring 2E will have been wound to a sufficient tension. The user then Vinserts the tress of Vhair to be curled in the slot IU formed in the 'spindle and presses the trigger 45. This releases the engaged arm of the lug 20, allowing the shaft IS to rotate in response to pressure from the spring 26 which causes the spindle 62 to rotate and wind the tress of hair thereon. Now it is merely necessary to disengage the curler comprising the spindle and arm by sliding it endwise away from the shaft I6 and guide 56. When'free of the guide 56 the collar 60 will spring inwardly to its normal diameter, thereupon tightly embracing the spindle 62 and preventing rotation therebetween. The curler may now be left in the tress of hair in the usual manner. The bar 58 will prevent the hair from uncoiling itself much in the manner of a bobby pin. The user is now free to slip another curler on the shaft I6 and repeat the operation with another tress of hair in the same marmer.

It should be noted that a, curler may be placed on either end of the housing H, thus facilitating use of the device in either hand. To obtain the proper direction of spindle rotation for an inside or outside curl as desired the user need only turn the instrument in his hand. It should also be noted that the ears 68 and 68a, the bracket 20, and the spindle slot 10 are in the same radial plane so that the slot l is always parallel to the handle at the time the user inserts a tress of hair therein.

The present embodiment is to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
