HAIR CURLING DEVICE Filed on. 28, 1949 7 5 aw H R w W H4 m mm m 6% United States Patent HAIR CURLING DEVICE Alexander C. Field, Sr., Cincinnati, Ohio, assignor to The Procter & Gamble Company, Cincinnati, Ohio, a corporation of Ohio Application October 28, 1949, Serial No. 124,093

Claims. (Cl. 132-33) This invention relates to hair curling devices particularly for imparting to the human hair a home permanent or cold wave.

In dressing the hair with a permanent wave it is customary to treat the hair with a waving solution. Then the tresses are wound around the curler usually by twirling the curler in the fingers. A tissue sheet may be used to enclose the strand or tress of hair to aid in the distribution of the solution and absorb any excess. Finally the curling device is wound close to the head and an elastic band is secured lengthwise to prevent the curler from unwinding. The hair is left in this condition a suflicient time to set and then the curlers are unwound and removed, and the hair is in condition for brushing, combing or otherwise arranging.

The use of such curling devices is very old, the earliest curler of the simple type described consisting of a cylindrical rod of wood with an elastic loop at one end and a slot in the other through which the other end of the loop is secured when the hair is wound around the rod. Such a device is shown in the Lavis and McMillan Patent No. 66,599 of July 9, 1867.

With the increase in the dressing of the hair with cold permanent waving solutions, a large number of different types of curling devices have been developed. Some of these operate on the principle of a safety pin with a main bar on which the hair strand is wound and a clamping member which may be fastened down to hold the bar in position wound closely to the scalp.

It is the object of my invention to provide a curling device which will be simple to operate, and easy to adjust to clamping position when the strand of hair is wound on the curling bar.

It is my object to provide in such a device for a two piece construction in which the two pieces may be made from stampings of plastic and which may be snapped together without further assembly operations.

I provide a cylindrical curling bar preferably tapered at its ends which will be free to rotate as the hair is wound upon it and a clamping member articulated to the bar in such a way that in closing the clamping member to clamping position the bar is held non-rotatably before clamping position is reached. I have found that such an operative device greatly facilitates its use and has the added advantage that the coiled strand of hair is held more securely without slipping during the interval in which the wave is being formed.

A further advantage of my preferred construction is that the clamping member has several settings for clamping position thereby accommodating itself for either thick or thin hair.

The foregoing object and other objects which will be described and explained, I accomplish by that combination of parts of which I have shown a preferred embodiment.

In the drawings:

Figure 2 is a side elevation of the device in the same position as is shown in Figure 1.

Figure 3 is a side elevation with part of the curling bar broken away in the position in which the curling bar is held from further rotation.

Figure 4 is a side elevation of the device in one of the positions of clamped adjustment.

Figure 5 is a sectional view along the lines 5-5 of Figure 2.

Figure 6 is a sectional view along the lines 66 of of Figure 2.

Figure 7 is a sectional view along the lines 7-7 of Figure 4.

- The curling bar is formed from a tapered cylindrical member 1, preferably having ribs 2 extending lengthwise and with a slot 3 extending into and along one of the ribs of the bar as indicated at 4.

At the free end of the member 1 there is a disc-like head piece 5 with a semi-spherical knob 6 formed up from the axis of the disc.

At the other end of the bar there is another cylindrical disc-like head 7 having preferably a hexagonal boss 8 integrally formed thereon and with a rod 9 extending from the boss carrying a spherical ball shaped member 10. The ball 10 forms a freely rotatable bearing for the curling bar as will be described.

The clamp member has a rounded body 11 with a clamping end 12 bent over at substantially a right angle and with a series of sockets 13 for seating the knob 6 of the curling bar in a plurality of positions as shown. The body 11 is resilient and acts as a bow which bends slightly when knobs 6 seat in the sockets 13.

The clamp member has bifurcated trunnion plates 14 having indentations or holes 15 into which the balllike member 10 of the curling bar fits with a snap fit due to the flexibility of the trunnion plates.

It will be obvious that in open position as shown in Figures 1 and 2, the curling bar will be freely rotatable, being swivele'd in a ball and socket joint. As the curling bar is swiveled however, to the position shown in Figure 3 opposite sides of the hexagonal boss will begin to ride down the recessed tracks 16 on the inner surfaces of the trunnion plates.

From this position until the device is clamped into one of the closed positions, the curling bar will be held in non-rotatable position. This is important in keeping the tress of hair firmly wound around the bar. If the rotation of the curling bar is not prevented until the end of the bar is clamped in closed position at the last instant before clamping the curling bar in closed position the hair may be released just enough to prevent a good tight curl. Thus my construction has advantages over devices which do not hold the curling bar non-rotatable before clamped position is reached.

As has been explained, the plurality of sockets 13 permits the curling bar 1 to be held in whatever position is best adapted to hold the curl of hair securely depending on its thickness.

The device is formed as has also been stated by two plastic stampings and the only assembly operation required is snapping the ball 10 of the curling bar into position in the indentations 15 of the trunnion plates 14.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A cold wave hair clip composed of two integrally formed members consisting in a curling bar and a clamp bar, the curling bar having a ball and socket swivel connection with the clamp bar, the clamp bar having trunnion plates adjacent the end which has the swivel mounting and the other end of the clamp bar shaped to temporarily secure the end of the curling bar opposite the swivel mounting in clamping position, said trunnion plates having recessed tracks and the curling bar provided with opposed flat surfaced portions to engage the track and maintain the curling bar in non-rotatable position.

2. The cold wave hair clip of claim 1 the curling bar of which contains a slot extending lengthwise therein for receiving the end of a lock of hair to be curled.

3. A hair curling device comprising a curling bar and a clamping bar connected at one end with a ball and socket joint, said bars being provided with cooperative locking means for clamping together their other ends when they are moved to closed position, said bars also being provided, adjacent their ball and socket joint connection, with cooperating elements which slidingly engage as said bars are moved toward closed position thus preventing rotation of the curling bar during closing of the curling device.

4. A cold wave hair clip composed of two integrally formed members consisting in a clamping bar having retaining elements at one end and, at the other end, bifurcated portions between which a socket is located, and a curling rod provided at one end with means for cooperating with the retaining elements on the clamping bar to hold the curling rod and clamping bar in closed position and said curling rod being shaped at the other end in the form of a ball which is engaged in the socket in the bifurcated portions of the clamping bar, said curling rod being further provided adjacent its ball shaped end with a hexagonal boss and said clamping member being further provided with a flat-sided passageway in the bifurcated portion of said clamping bar, the 'width of said passageway being just sufiicient to permit the hexagonal boss to pass therethrough when d the flat sides of the said hexagonal boss are in sliding contact with the fiat sides of said passageway.

5. A hair curling device comprising a clamping memoer and a curling bar, one end of the curling bar being swiveled to one end of the clamping member providing a freely rotatable bearing for the curling bar, said clamping member and said curling bar having, adjacent their swiveled ends, interengaging parts which slidingly engage and prevent rotation of the curling bar during the closing operation as the curling bar is moved toward the clamping member, said curling bar and clamping memher also being provided with cooperating latching elements for holding their ends opposite the swiveled ends in closed clamped position, and the interengaging parts adjacent the swiveled ends of the clamping member and the curling bar consisting of channels in the inner faces of opposed flanges extending from the clamping member and a section of the curling bar having such size, shape and location that opposed flat surfaces thereof are slidingly out nonrotatably received in the channels.
