HAIR WAVING APPLIANCE Filed Aug. l5 1929 il v M//mm Patented Oct. 21, 1930 PATENT for-FICE wILLrAM e..k sHEL'roN, or s'r. Louis, MIssoUnr HAIR-Wimmer ArrLIAncE application mea August 15,1929. serial No. 386,006.

My invention relates to the art of hair waving and consists in a novel heater, and clamping and heating structure to be used in the permanent waving of hair.

i One of the objects of my invention is to to the scalp of the user than the devices of the prior art have been able to produce.

Another object of my invention is to protect the scalp of the user from injury due to heating of metallic portions of `my device or descent of moisture.

In the accompanying drawings which illustrate a selected embodiment of my inventionl Figure. 1 is an end elevationeof the assem- 25 bled structure. v

Figurel 2 is a side view of the same.

Figure 3 is a top view of the clamping structure. l v v I Figure 4 is a vertical section taken on 3o the line 4 4 of Figure 2, showing the vhair wound on the rod and the-supply unit and heater applied over the same.

The heater member has an varcuate body:

1 Vcontaining an electric:I resistance heating element and mounting a block 2 of insulat-v ing material on its convex surface. Vclips 3 are attached to each side of the block 2 and each clipv comprises an end portion secured tothe top of the sideof the block by screws 4, or other suitable means, anda horizontal intermediate portion and an outer lower portion 5 spaced from the bloc-k 2 and 'below the same. a

Separately formed arms .6 are mounted upon the outer portions 5 o f the spring clips and have inturned flanges 7 at the top that ,Y

`bear against the upper portion gf clips 3 adjacentv to where the sameare secured to block 2.- The lower portions of arms 6 form Wings 8 conforming to the contour vof the Spring f" arcuate body 1 and terminate in jaws 9 extending under the lower edgesof member 1. Jaws 9 are adapted to project to grip the strand of hair T and supply P. The jaws 9 are opened by means of handles 10 secured 55 to yarms l6 at 43 below inturnedflangesI 7 and projectin above flanges 7. By pressing the hand es together above flanges 7, the jawsare pushed apart, flanges 7 acting as fulcrum bearings on the spring clips adjacent to where the same are secured to block 2. It will be understood that the spring clips 3 hold or tend to hold the jaws in the full line position shown in Figure 1, but the 'aws may be opened to permit application or 65 removal of the heater member to and from the cylinder-like body formed by the strand of hair wrapped about the rod 26 and enclosed in the supply P.

By mounting the arms 6 as shown, the 70 structure is made more desirable to use as compared with devices which have exposed hinges and springslikely to snag the hair and as compared with the structure disclosed inl my copending application, Serial Number 333,895, led January 21, 1929.

In my present device, the handle fulcrum is independent of the spring and is at the upper. end of the block, and the spring is of substantial length and the full length of the spring functions in closing the jaws. This is a better construction thanl that shown in my copending application in which the spring forms' the fulcrum and only a restricted portion of the spring can Hex.

Plugs 11 are provided in the' top of block 2 for insertion into terminals of 'a heater cord 'where the same maybe quickly'disengaged from the heater in case of an emergency of any kind. y,

The scalp of the customer isindicated at S and'T is a strand of hair. P is asupply pad. The strand will be gripped adj acentto the scalp by a clamping and curling member which is associated with theheater and hair engaging member and is adapted to engage andl-curlthe hair between the heater and the' scalp of the user.

The clamping and curling member re-v ferred to is composed of bars12 and 13 of Ibo bakelite or other suitable material which are hinged together at 15 by bar 16 secured to bar 13. Suitable catch elements, 17 and 18.

are provided at 12 and 13. l

' Bar 12 has channel shaped horizontal faces and concave vertical faces and has a covering 19 of resilient material.

Bar 13 is mounted on a heat insulating member 20 adapted to rest on the scalp of the user and has a metallic member contacting with the bottom of the inner vertical face of bar 13 and secured to the upper horizontal face of the bar by rivets 21 orlke means. This metallic member forms a flange 22 eX- tending between the vertical faces of bars 12 and 13 and is shaped to fit the contour of the rubber covered face of bar 12. The metallic member continues along the surface ofthe top horizontal face of bar 13 to form a folded tongue 23 and curves up from the top of the inside face of the bar 13 to form the curved flan e24. L y

F anges 22 and 24, in conjunction wit-h bar 12 are adapted to wave-the strand T much nearer the scalp than is possible when using any of the devices of the prior art and even nearer than is possible when using the device disclosed in my copending application,'Serial Number 333,895 filed January 21, 1929.

The above clamping and curling structure is provided with a pawl 25 which is mounted on member 16. A curling rod shown at 26 has a ratchet 27 at one end which is engagedv by the pawl 25 as the rod is rotated to wind the hair. The engagement of the pawl and the ratchet prevents the rod from unwinding and loosening the roll of hair. The tension on the hair and the action of the pawl against the ratchet are such as to hold the rod, wound with hair, against the clamp. s

To apply the device to a strand of hair, the clamp is applied to the strand T close to the scalp S and bars 12 and 13 are locked together by elements 17 and 18. The curling rod is then applied to the outer end of the strand and turned to wind the hair on the rod until the same is adjacent to the clamping jaws where the pawl 25 engages the ratchet- 27 and holds the rod 26 from unwinding when the same has been wound enough to create tension on the strand T. Then the supply element P is placed around the hair wound onl the rod, and the lower edges of the supply are pushed under the roll of hair so that the supply contacts with the metallic 'tongue'23- The heater is then placed over the supply. Heat from the heater thengenerates steam within the moist supply unit which heats the metal member including flanges 22 to' 24 whereby heat is applied to the strand of hair between the base of the clamp and the beginning of the outermost spiral ofthe roll of hair on rod 26.-

The metallic fiange 22 presses the hair the' unhinged ends of bars tightly into the recess formed by the rubber covered face of opposing jaw 12 to seal the clamping jaws so that no moisture can pass through the same to the scalp of the user. The felt pad 20 presses the hair 'tightly against the rubber covering of the bottom of the face of jaw 12 to prevent the heat and moisture from passing from the flange 22 to the scalp of the user.

Obviously, many of the details of the described structure may be varied without departing'from the spirit of my invention and I contemplate the exclusive use of all of such modifications as come within the scope of my claims.
