\ E. A. TEFFT PROTECTOR FOR PERMANENT WAVING MACHINES May 4,

Filed Feb. 5, 1947 INVENTOR. fDWARD ARTHUR TEFFT BY p 2 l I a ATTORNEY.

Patented May 4}, 1948 fiT-A'IES PATENT PROTECTOR FOR PERMANENT -WA-V!NG MACHINE S My invention relates to devices used in the art of hair curling and particularlyto devices forholding locks of hair in tightly curled condition while subjecting them to heat in order to .give 'the'hair a permanent wave.

-Ingiving'hair a permanent wave treatment it is necessary to clamp each lock of hair to be cu'rled in a small device acting to hold the hair in a tight curl, the device being then placed, holding the tightly curled lock, in a heating unit of a heating machine for a sufiicient length of "timetoset the curl, after which time the heating unit is removed and the lock of hair released -fromthe device. Curling of the hair is generally required from as close as possible to the root of the hair to the tip, and the hair should be stretched while in curling position.

In order to hold the lock of hair so thatithe treatment causes no discomfort either from the ,heatof'the heating unit or from the hair being z-pulledirom the scalp, devices of the kind to whichthe invention relates comprise a small clamp to hold each lock of hair to be treated and a spool or mandrel mounted on-the clamp, on whi'ch'the lock of hair may be tightly wound and securely retained in wound condition during the heating operation.

g The clamps should be readily releasable when the heating is completed, without pulling the 'hair and causing discomfort to the customer. Various devices of the kind referred to have been "proposed or are in use, but to the bestof my knowledge possess disadvantages such as undue complication or the provision of several separablepartsv and the like.

"It is an object of my invention to provide a :novel device for use in permanent wave treatiment comprising only a simple clamping device Tcarrying a one way winding mean's'for a spindle forming apart of the device.

'It is another'object of my invention to provide 'ano'vel device of the kind describedadapted to 'useither wooden or metallic spindles of .simple form, and which are inexpensive to manufacsure, since the spindle is not furnishedwith any cooperating parts requiring accurate machining.

ltis a further object of my invention to provide-a novel device of the kind describedin which aspindle, on Which-the hair is wound,

' is-carried bya clamp holding. alock of hair; by

a moun-ting; and operating arrangement permit- -iting--thespindle to be releasedcifrom therclamp iwitma minimum of movement of .the spindle rela- -tiveito the bodyof the clamp.

A still further object of my invention is to .provide a novel device of 'the kind described in which a simple clamp is provided withasingle clamping and Winding element permanently attached to the clamp and co-operating with a pable of being quickly and easily secured imposition and disengaged from operational ,position, and also in connection with which either a metal, but preferably a wooden mandrel may be used.

.Other objects, advantages and .features of invention may appear 'frornjthe accompanying drawing, the subjoined detail description and the appended claims.

The accompanying drawing iliustrates the, invention in a form I at present deempreferable.

Figure 1 is a plan view of the device of, my invention in open position and with the mandrel removed for purposes of clearness.

Fig. 6. is a detail partl in sectionon further enlarged scale, as viewed on line E.ii,- Fig. 2.

'Fig. 7 is a section of theratchet and flocking mejanstaken on line 'i'i,. Fig. 6.

In Fig. 1 the numeral it indicates one c1amping' barpivoted at E2 to the offsetend Hi ofE a second clamping bar It. The clamping members or bars it and i6z-maybe made-pb strip metal and are covered with rubber sheathing E8 serving both to give asecure g-rip .of vthe;rnem- .bers on a. lock of. hairand to, insulate,,from-the .scal-p of the person undergoing. treatmentthe bars, :which .many times get quite hot.

A portion of ofiset I4 is bent up to form a hearing 20 in and against which a cylindrical end 2| of a mandrel or spindle 22 is mounted when a lock or tuft of hair has been wound around the spindle 2-2 and the lock of hair is clamped between bars l and 16.

The clamping members I0 and (6 are adapted to be brought into engagement with one another by means of a double armed link 24 pivoted at 26 to the free end of clamping member l6. At the free end of the link 24 and between the arms of the link on a stem 30 passing through both arms of the link 24, a cam 28 is mounted and which cam is rigidly secured on the stem in any suitable manner as for instance by soldering or brazing it thereto. A bushing 32 is fitted on and secured to one end of the stem, and a spring washer 36 is arranged between a head 34 on the oppositely projecting end of the stem and the adjacent arm of link 24, thus bushing 32 is drawn toward the opposite arm of the link.

A combined operating member and rotary bearing assembly 36 is formed by a strip of sheet :metal bent to embrace the bushing 32 and is pinned thereto as indicated at 38. The ends of the strips are formed into a bearing 39 for a circular disc 40 and support it for rotary motion. The disc 40 is provided with a laterally extending :finger piece 4'2 by which the hearing may be turned about the axis of the bushing 32, and the link 24 may be swung about pivot 26. The edge of disc 40 is provided with serrations 44 and a spring detent 46 positioned between the lower end of sleeve 32 and link 24 is arranged with its end 7 Y 48 projecting into the rotary bearing to engage the serrated edge of disc 49 to permit rotating of said disc 40 in one direction only.

It will be noted that the arrangement described will permit disc 40 to be turned in a direction such that the serrations ride under the end 48 of .spring detent 46 but cannot be turned in the op- ;posite direction since the serrations will engage against the end 48 of the detent.

A square aperture 50 is cut in the disc 40 and "the finger piece 42 is recessed at 52 to enable :the squared end 56 of the spindle 22 to be inserted :into the square hole in the disc 49 and recess in ithe finger piece.

Spindle 22 is preferably made of wood since "this material is a poor conductor of heat, .but as it is sometimes desirable to supply extra heat :at certain points of a head of hair or under certain conditions a metal spindle may also be used.

In using the device of my invention, a lock or tuft of hair is separated from the remainder of a persons head of hair and clamped between the clamping members It and I6 by closing the bars on the lock of hair and swinging link 24' toward and onto the end of bar In with the operating member 36 extending forwardly beyond the link, in which position the low portion of cam 28 can pass over the projecting end 29 of bar Ill. The operating member is then swung toward the link with the finger piece 42 away 65 from the clamp thus bringing the high point of the cam against end 29 and clamping bars l0 and i6 together. The lock of hair may then be moistened with any desired preparation and wound upon the spindle 22.

When the tuft of hair is wound around the spindle so that the spindle approaches the clamp, the cylindrical end 2| of mandrel 22 is placed against the fixed abutment 20, and the squared end 56 is inserted in the square hole in the rotary bearing 36 and the hair is further tightened around the mandrel 22 by turning finger piece 42 to wind the hair tightly therearound. The hair may then be moistened or treated as required, wrapped in a protective cover and placed in a heating unit of any suitable heating machine. The described procedure is carried out with all portions of the hair required to be treated.

When heat has been applied for the required length of time the devices are removed from the heating units, and by swinging the rotary bearing assembly away from the spindle 22, the spindle may be easily and quickly removed from the clamp and from the curled hair, the clamping members In and it are then released by swinging the assembly 36 to the position shown in-Fig. 4 so as to remove the cam pressure holding'the clamp bars Ill and 16 together and then by swinging the link on which the rotary bearing is mounted clear of the end 29 of clamping member II! as shown in Fig. 1.
