DEVICE non PUTTING PERMANENT WAVES 11N HAIR.

Application 1ed August 4, 1926. Serial No. 127,103.

The present invention relates to devices for putt-ing permanent waves in hair, and aims to provide a novel and simple device for 'that purpose which is simple, practical and etiicient in use.

Another object ot the invention is the provision ot such a device which will put permanent waves in hair by a trictional rubbing and clamping action, without requiring heat, and by means ot which the structure of the hair is deformed to put permanent waves therein.

A further object is to provide a device of the kind indicated comprising two members adapted to be moved together with the hair betweenv them and formed with novelv portions adapted to engage one anotherl and operate on the hair between them in such a manner as to put the waves in the hair.

lith the foregoing and other objects in view, which will be apparent as the description proceeds, the invention resides in the construction and arrangement ot parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a side elevation of the device, portions being shown in longitudinal section.

Fig. 2 is an enlarged cross section on the line 212 of Fig. 1.

Fig. 3 is a cross section on the same line as Fig. 2 showing the parts moved together.

In carrying out the invention, there is provided a channel-shaped member 7 of sheet metal or other suitable material which has the bottom 8 and sides 9, and the sides 9 are provided with the inturned flanges 10 provided with the depending secondary tlanges 11 extending toward the bottom 8. fit-hin the member 7 is disposed a pair of elongated plates or strips 12 of sheet metal or other suitable material, extending longitudinally along the flanges 11 and across the edges ot said flanges. The plates 12 are provided attheir opposite edges with outstanding flanges 13 overlapping the langes 11 behind same, and the plates 12 are provided at their adjacent edges with the rounded beads or portions 14;. The plates 12 are thus disposed across the longitudinal opening or slot between the flanges of the shell or mem ber 7, and the beads 14 are normally spaced slightly to permit the hair to be Withdrawn from between them.

A core or filler 15 of rubber or other compressible or resilient material is disposed within the member or shell 7, and provides a cushion below the plates 12 to yieldingly support said plates in their normal common plane, as seen in Fig. 2. The core or cushion 15 has a longitudinal groove 16 therein below the space or slot between the adjacent edges of the plates 12 and the beads 14 overlap thefopposite walls of the groove 16 along the edges of said groove.

The elements above described constitute one part or member of the device, and the other' part or member of the device comprises a bar or lever 17 having a blade 18 adapted to enter the firstnamed part ot' the device. As shown, the two parts are hingedly connected at one end. Thus, the flanges 10 have outstanding ears 19 between which the corresponding end of the bar or lever 17 is pivoted, as at 20, and the adjacent end portion oit the blade 18 is rounded off, as at 21, so as to conveniently enter and leave the slot between t-he plates 12. The member or shell 7 and lever 17 are provided at the ends thereof opposite to the hinge with the handles 22 and 23, respectively, whereby the two parts or members may be conveniently moved together and apartl by hand. V V

n The blade 18 may be of suitable thickness, and itsedge is rounded, in order to put a vave lor kink of desired magnitude in the ian'.

In using the device, the two parts are separated and a suitable number'of strands of hair are brought between the two parts with the strands extending transversely across the flanges 10 and slot between them. The handles 22 and 23 are then moved toward one another, which will forcibly move the blade 18 between the plates 12, and in doing so the plates 12 are pushed downwardly at their adjacent edges and are separated, as seen in Fig. 3. The depression of the plates 12 will also compress the core 0r cushion 15, and the groove 16 will receive the edge portion 0f the blade.

The hair is bent across the edge of the blade 18, as said blade passes between the plates 12, and the loops of hair thus formed are forced downwardly between the plates l2, and move with a frctonal rubbing action across the adjacent rounded edges or portions 1li of the plates 12 during which the plates 12 are pressed by the cushion or core 15 tightly against the opposite sides of the blade 18, and this action will deforni the structure of the hair in a way to obtain a. permanent wave in each strand of hair. rllhe waves are thus set permanently 1n the hair, and after the parts are separated so as to withdraw the blade 18 from between the plates 12, the hair may be withdrawn. he operation is repeated for the same strands of hair if a series of waves are desired. lt will be noted that when the blade has been forced between the plates 12, so that said plates are swung inwardly as seen in Fig. 3, said plates will resist the withdrawal of the blade by a toggle action, the flanges 13 of the plates bearing against the cushion or core 15 to yieldingly move the plates against the blade. Thus, when the blade is withdrawn there is a tendency' to swing the plates outwardly with the blade, thereby producing a further frictional rubbing and clamping action between the blade and plates to effectively deform or distort the structure of the hair. This action 1s even more effective than the action which takes place when the blade is moved between the plates, because the pressure between the blade and plates is greater due to the fact that the plates tend to swing together while the blade is being withdrawn.

Having thus described the invention, what is claimed as new is 1. A device of the character described comprising a pair of members, a blade movable between them, and means for yieldingly mounting said members so that they may be swung by the contact of the blade with said members and may be separated when the blade is forced between said members.

2. A device of the character described comprising one part having a pair of yieldingly-mounted members, and another part having a portion to move, with hair between said parts, between said members with a frictional rubbing and clamping action, said members being arranged to be forced apart by said portion when said portion is moved between them.

3. A device of the character described comprising one part having a pair of yieldingly-mounted plates, and another part having a blade movable between the adjacent edges of said plates, said plates being arranged to be forced apart by said blade when the blade is moved between them.

ll. A device of the character described comprising a shell having a slot, a` pair of plates disposed across said slot, yieldable means in the shell supporting said plates, and a blade movable between said plates, said plates being arranged to be forced apart by said blade when the blade is moved between said plates.

.3. A device of the character described comprising a shell having a slot, a pair of plates disposed across said slot and adapted to swing` inwardly at their adjacent edges, a yieldable cushion in said shell supporting said plates, and a blade movable between said plates, said plates being arranged to be fo-rced apart by said blade when the blade is moved between said plates.

6. A device of the character described comprising a channel-shaped shell having inturned flanges provided with secondary flanges extending into the shell, a pair of plates extending across the space between said flanges and having outwardly extending flanges at their opposite edges engaging behind the secondary flanges, a yieldable cushion in said shell support-ing said plates, and a blade movable between said plates, said plates being arranged to be forced apart by said blade when the blade is moved b'etween said plates.

7. A device of the character described comprising a pair of yielding members, and a blade movable between them, with hair between said members and blade, with a frictional rubbing and clamping action, said members being arranged to be forced apart by said blade when the blade is moved between said members.

8. A device of the character described comprising a shell, a pair of plates mounted yieldingly therein and having adjacent edges, and a blade movable between said edges of the plates with a frictional rubbing and clamping action, said plates being arranged to be forced apart by said blade when the blade is moved between said plates.

.j In testimony whereof I hereunto affix my signature.
