8 Claims.

This invention relates to a curler spindle for hair wavers,

More particularly, the present invention has to do with a curler spindle for hair wavers of the type in which the waver comprises a protector clamp and a curler spindle, the protector clamp being applied to the lock of hair close to the scalp and the hair being wound upon the spindle which is then usually mounted on the protector clamp and turned to tension the hair, whereupon a pad and heater are applied for purposes well understood in the art.

Heretofore, these curler spindles have usually been made of light weight metal which permitted them to be formed solid without undue weight upon the head. The light weight metal suitable for making curler spindles of this sort is not now readily available due to war priorities.

One of the main objects of the present invention is to provide a curler spindle of simple, relatively inexpensive and improved construction, and, more particularly, a curler spindle formed of sheet metal shaped to tubular form to make the spindle light in weight, and an improved curler spindle of the character set forth having end members formed to strengthen the spindle against collapse and secured to the ends of the spindle in a manner to accomplish the desired results.

Another and more specific object of the invention is to provide an improved form of tubular curler spindle which is not only light in weight and relatively strong, but which is provided with improved journal portions for journaling the spindle for rotation upon the protector clamp; also, in conjunction with a curler spindle of the improved form set forth, an improved form of ratchet for cooperation with the usual or any suitable form of pawl to prevent unwinding of the hair from the spindle, and an improved form of finger piece for turning the spindle after it is applied to the clamp.

Further objects and advantages of the invention will appear from the following detailed description, taken in connection with the accompanying drawings in which:

Figure 1 is an elevational view of a curler spindle embodying the present invention, and showing the same applied to a protector clamp;

Figure 2 is an elevational view of the curler spindle alone and taken at substantially right angles to Figure 1;

Figure 15 is a view similar to Figure 2 showing a modified form of curler spindle embodying the present invention.-

Referring now in detail to the drawings, the hair waver selected for illustration comprises a protector clamp l0 and a curler spindle H.

The protector clamp l0 may comprise pivoted jaws adapted to be clamped to the lock of hair close to the scalp, as well understood in the art. The protector clamp I0 is shown as having upturned supports I2 and I3 to receive and support the curler spindle lil with the hair wound thereon and in such manner that the spindle ll may be turned to tension the hair, also as well understood in the art. A spring pawl M on the protector clamp cooperates with a ratchet on the curler spindle I I to prevent retrograde movement or unwinding of-the spindle I I.

The-curler spindle ll to which the present invention is directed is formed of flat sheet metal stock of suitable gauge which is blanked out to the form shown at I la in Figure 4. The blank I la is placed, for example, upon a mandrel is shaped externally to conform with the internal form of the finished tubular spindle H. The blank Ila is then folded or' closed around the mandrel lg with the opposite edges 19 of the blank (Figure 4) brought into abutting engagement at 20 (Figure 5). A holder member 2| may be provided for holding the blank Ila in place during the forming operation. For the purpose of closing the blank Ila around the mandrel I8. I have shown rollers 22, but this may vary widely within the scope of the present invention. It is to .be understood, for example,that the blank I in may be folded first to generally U-shaped form in cross section and then closed to complete the;

formation of the tubular spindle. v

The resulting curler spindle is of hollow or tubular form having cylindrical ends-24 and 25 and of circular cross section, diminishing in diameter from the opposite cylindrical end to the intermediate portion of the spindle centrally between its opposite ends. The mandrel [8 may be divided between its ends to permit the opposite ends of the mandrel to be pulled out endwise upon completion of the spindle forming operation, or the mandrel may be of any other character adapted to be removed from the spindle.

The cup-shaped shell 26 at one end of the spindle l l is drawn or otherwise broughtto cupshaped form from a circular sheet metal blank 26a. The end wall 21 of the shell 26 is preferably pressed inwardly to fit within the interior of the adjacent end of the tubular spindle II (as shown in Figure 14) thereby holding the tubular spindle against collapse atone end. An opening 28 is punched in the end wall 21 centrally thereof. The opening 28 is shown of generally circular form, but it may be of rectangular or other suitable non-circular form similar to the opening in the cup-shapedshell at the opposite end of the spindle H as will presently appear.

External ratchet teeth 30 are formed in the cup-shaped shell 26 for engagement with the pawl l4 on the protector clamp. These ratchet teeth may be formed, for example, by forcing the cup-shaped shell 26 through a die 32 by means of a punch 34. The die 32 has internal teeth 33 for forming the desired external ratchet teeth 30 on the shell 26, and the, punch 34 has external teeth 35 corresponding with the internal teeth 33 within the die 32 with the thickness of the metal shell 26 between the teeth. The shell 26 may be held in place on the upper ends of the teeth 33 (as shown in Figure 8) until the punch 34 enters the shell 26 and forces the same through the die 32, but this may be varied within the scope of the present invention. By the method disclosed the shell 26 is ejected from the die 32 by the ratchet tooth forming movement of the punch 34 which operates to force the shell through the die from one end t form the teeth on the shell and to force the shell with the teeth thereon out from the opposite end of the die. The cup-shaped shell 40 for the opposite end of the spindle II is similarly drawn or brought to cup-shaped form from a circular metal blank 40a. The end wall 4| of the shell 40, like the end wall 21 of the shell 25. is preferably pressed inwardly to fit within the interior of the adjacent end of the tubular spindle to hold this endof the spindle against collapse. An opening 42, pref erably of rectangular or other suitable'non-circular form, for a purpose which will presently appear, is punched in the end wall 4| centrally thereof. A pin is riveted at 46 in the opening 28 in the end of the shell 26. This pin 45 has turning movement in the support l2 when the curler spindle H is mounted on the protector movement in the support l3.

The

shels

26 and 40 are pressed into place upon the opposite .

cylindrical ends

24 and 25 of the curler spindle H, the pressed fit of the shells on the endsof the curler spindle being of a character, to fix the shells securely in place and prevent turning movement of the same on the ends of the spindle. The shell 26 having the ratchet teeth 30 for cooperation with the pawl I4 is more subject to becoming loose on the spindle ll than is the shell 40 at the opposite end of the spindle. If the shell 26 does become loose on the spindle, the pawl l4 will fail to prevent unwinding of the spindle. Therefore, in pressing the shell 26 into place on the spindle l I, I preferably force the inner end of the annular wall of the shell inwardly so that it and the inner ends of the ratchet teeth 30 actually bite at 50 (Figure 14) into the tubular wall of the spindle. This very effectively fixes the shell 26 against turning movement relative to the spindle II. If desired, the inner end of the annular wall of the shell- 40 at the opposite end of the spindle may be similarly forced inwardly so that it will actually bite int the tubular wall of the spindle to preclude relative turning movement between this shell and the spindle.

The saddle-like retainer 52 has at one end projecting tongues 53 which are pivoted on the shell 40, for example by means of a cross pin 54, the ends of which may be riveted over to prevent displacement of the pin after it is applied through the registering openings in the tongues 53 and the adjacent end of the spindle. The retainer 52 is i usually curved to conform with the'periphery of the spindle and is adapted to be swung away from the spindle for introduction of the strands or look of hair between the spindle and the retainer, which is then closed to grip the hair between the spindle and the retainer; as well understood in the art. I

The handle 56 for turning the spindle to wind the hair thereon is preferably formed of thin metallic. tubular stock indicated fragmentarily, for example, at 56a in Figure 12. Upon first cutting this stock to form an endless ring shown at 56b in Figure 13 of the desired length, this ring is placed, for example, between a. pair of forming dies 58, 59, and preferably with a pin correpending with the pin 41 concentrically within the ring 561) as shown more or less diagrammatically in Figure 13. The forming dies 58, 59 are then closed to bring the annular ring 561) to the form of the handle 56 as shown in Figure 3; Before completingthe flattening of the flattened portions of the handle 56, the pin 60 is preferably withdrawn to permit the flattened portions of the handle tobe pressed tightly together. The intermediate hub part 62 of the .handle is then pressed onto the pin 41 and may be spot-welded at 63' (Figure 14) or otherwise fixed securely against turning movement relatively to the pin 41.

The resulting curler spindle which is now ready for use in the usual manner is of relatively great strength, particularly against collapse which otherwise might result due to its tubular form. The spindle is of light weight notwithstanding the fact that the lighter weight metals are not readily available due to war priorities, and the improved construction set forth permits employment of sheet stock with the advantages set out.

The embodiment of the invention illustrated in Figure is the same as the other embodiment except that in Figure 15 the ratchet teeth 30 are formed in the shell 40' at the handle end of the spindle. This may be accomplished by lengthening the shell 43' to provide for the teeth 30' and at the same time permitting pivoting of the retainer 52 to the shell 40' by the pin 54'. In this case the shell 25 at the opposite end of the spindle conforms in general with the shell as shown at 40 in the previous embodiment of the invention.
