CURLING DEVICE Filed March 15, 1941 INVENLIOR. fins-Z 1? Patented Dec. 2, 1941 PATET QEICE 7 Claims.

This invention relates to hair curling devices, and is particularly concerned with a new and improved hair curling rod comprising stamped, rolled or drawn parts which are assembled together to form the rod.

The curling device or curling rod forming the object of the invention is used in conjunction with aholder (usually termed protector) which is made of two hinged and suitably padded parts. The holder is positioned close to the head and holds a strand of hair near the roots thereof.

The curling rod heretofore used with such a holder or protector is made in one embodiment in the form of an integral machined rod equipped at one end with a handle, a ratchet and a journal portion for engagement with a suitable bearing projecting from the holder. At the other end the old curling rod carries a second integral journal portion for engagement with a companion bearing on the holder. The tip of the strand of hair is attached to the central portion of the integral curling rod by means of a suitable clip hingedly provided thereon, and the rod is then twisted or rotated so as to wind the strand of hair on it, gradually shortening the distance between the curling rod and the holder until the journal portions of the curling rod are near the holder and are inserted into the bearing portions thereof. The ratchet then engages a suitable detent provided on the holder. tional twisting or rotating of the curling rod tightens the strand of hair, the ratchet and detent providing for retaining the tightening pull and stretching the coil of hair on the rod. Suitable packing and/or heating is then applied to the tightened assemblage to set the hair wound on the curling rod. Upon finishing the operation, the strand of hair is unwound, combed, and set to form the wave shape imparted thereto.

Some of these curling devices are made without a ratchet on the curling rod. They are instead equipped at one end with a polygonal rotatable journal portion engaging a polygonally formed fixed bearing on the holder. The polygonal journal projects into the curling rod at the corresponding end thereof (opposite the handle end) and holds a spring in frictional engagement with the rod inside thereof so as to permit the polygonal journal (and thereby the curling rod) to turn in only one direction. This spring-polygon assemblage thus takes the place of the ratchetdetent assemblage of the previously described embodiment.

The above noted device in either embodiment and the operation thereof are well known. The

Addl- 3 stamped or drawn cap l5.

curling rod was made integral of a machined piece requiring relatively expensive labor and consuming considerable material.

The object of the present invention is a curling rod mainly made up of a plurality of stamped, drawn or rolled parts. The curling rod, as made according to the invention, consumes less material, requires less labor, and furnishes a curling rod which combines with these advantages all the virtues of previously known curling rods. The new curling rod may be provided with a ratchet for coaction with a holder having a detent, or with a polygonal journal for coaction with a holder which is not equipped with such detent.

The invention will now be described with reference to the accompanying drawing, wherein- Fig. 1 is a plan view, on an enlarged scale, of one embodiment of the new curling rod;

Fig. 2 represents an exploded View of the device illustrated in Fig. 1, showing the individual parts on an enlarged scale; and

Figs. 3 and 4 illustrate, on an enlarged scale, a journal cap and a ratchet cap, respectively, for use in connection with another embodiment of the curling rod.

Referring now to the drawing, wherein like parts are designated by like reference numerals, the new curling rod comprises a central section H which is made by stamping and/or rolling operations and is thus of tubular structure. The rod .may be roughened in its central portion, as indicated. A hollow stamped cap I2 is attached by press-fit engagement to one end of the central section H. Numeral I3 designates a journal member which is. of polygonal shape for fixed engagement with a bearing member I l. The latter forms part of the previously mentioned holder or protector. At the other end of the central section II is provided a hollow This cap holds the handle IS in engagement with the central section H and against rotation in a manner to be described later on. The handle I6 has a circular shank including a journal section I! for rotatable engagement with the bearing I8 provided on the holder. Numeral l9 designates a pin driven through the central curler section I l and through the shank of the handle I6 which projects thereinto so as to hold the handle against longitudinal displacement. The pin may also form a journal for a clip (not shown) hingedly attached to the red I! for holding the tip of the strand of hair upon initiating the winding action. A separate journal pin may be used for mounting this clip, if desired.

The individual parts of the above described assemblage will now be described with reference to the exploded view, Fig. 2.

First to be considered are the parts shown at the left end of the curling rod II. The cap I2 is slipped on the barrel portion 2| of the journal member so that its end engages the shoulder formed by the (larger) polygon I3 which is integral with the barrel. The flat coil spring 23 is then slipped on the barrel portion 2| of the journal member. One end of the spring is angularly bent, as shown at 23, for insertion into the slot 24 provided on the barrel 2|. The end 23 of the spring 20 is riveted in place in the slot 24 of the barrel 2| and thus forms an assemblage with the journal member I3/2I and the cap I2. This assemblage is attached to the left hand end of the tubular central curler section II by inserting the spring thereinto. The cap I2 is made for press-fit attachment to the outside of the tubular central section II to hold the journal member I3 with its barrel 2| and spring 20 attached thereto in place. The journal member I3/2I can be twisted in only one direction, namely. in the direction of tightening the spring. If it were intended to rotate it in the opposite direction, the spring would tend to expand and in spreading would produce friction against the inside wall of the central curler section II, preventing such rotation. The radially disposed face or end wall of the cap I2 is positioned between the polygon and the outer end of the spring and the spring is attached in turn to the barrel 2i. The journal I3/2I and the cap I2 are each made of a single stamped piece.

The handle I6 is made of a stamped blank formed by an additional stamping operation or operations into the shape shown in the drawing at the right end of Fig. 2. The blank is folded in the middle and the two sides 25-46 thereof are bent upon each other as shown, forming the shank which comprises the two parts 2'! and the journal portion I1 for rotatable engagement with the bearing I8 (Fig. 1) provided on the previously mentioned holder. The blank for making the handle is shaped so as to provide a slot 29 on either side of the shank 21. A hole 3!] may be provided in the shank for receiving the pin I9 which is inserted through the hole 3| in the end of the central section II. The outside diameter of the shank 21 corresponds substantially to the inside diameter of the rod II at the right hand end thereof.

The cap I5, which may also be a stamped or drawn piece, is provided with a rib 32. thus divides the cap I5, providing thereon the two

apertures

33 and 34. The inside diameter of the apertures corresponds substantially to the outside diameter of the central curler rod II at the right hand end thereof and for press-fit engagement therewith. The cap is pressed into position on the end of the curler rod II with the rib 32 engaging the grooves 40. The cap is thus firmly attached to the rod II and is held against rotation by the rib 32. The end of the cap I5 is flush with the end of the curler rod. The shank 21 of the handle consisting of two parts separated by the slots 29 is pushed through the

apertures

33 and 34 now at the end of the curler rod since the cap is attached to the rod, and the shoulder on the shank merging over into the journal portion I1 is substantially in alignment with the end of the curler rod. The rib 32 holds the handle against rotation. The pin I9 may then be inserted through the holes 3 l-30, which The rib are in transverse alignment, for securing the handle against axial displacement. The pin also holds the handle additionally against rotation. The rib 32 on the cap I5 thus constitutes a means for holding the handle against rotation relative to the central section I I independently of the pin.

The curling rod assembled as described above forms the structure shown in Fig. 1. The central curler section II, as already mentioned, may be provided with a stamped clip (not shown) for holding the tip of the strand of hair that is to be wound thereon.

The holder or protector may consist, as previously intimated, of a simple appliance comprising two hinged, suitably padded parts for clamping together a strand of hair close to the head of the person whose hair is to be waved. The strand of hair projects from this clip holder. The curling rod shown in Fig. 1, comprising the parts described in connection with Fig. 2, is used for winding the strand of hair. The operation is as follows:

The tip of the strand of hair is put on the central section II and held there with aforementioned clip. The operator then rotates the curling rod II by means of the handle, thus winding the hair on the central section thereof, gradually shortening the strand of hair. When the winding operation has proceeded to a point approaching the head of the person, where the protector is positioned, the operator will insert the polygonal journal section I3 into the bearing section I4 of the holder, and the corresponding round journal section I! of the handle into the bearing I8 on the holder. The rotation of the curling rod can proceed in only one direction, due to the assemblage of the journal barrel 2I and spring 20, inside of the left end of the curling rod. Therefore this barrel 21, the journal I3 and the spring 20 function in the nature of a ratchet, preventing rotation of the curler rod in one direction while permitting it in the other. In rotating the rod in the proper direction the operator tightens the coil of hair wound thereon. A suitable packing may then be applied, either alone or in conjunction with heat, so as to set the coil of hair wound on the curling rod. After a certain time has elapsed, the strand of hair is unwound from the rod and the clip holder is released from the head, whereupon the strand of hair may be set to form the wave imparted thereto.

Figs. 3 and 4 show two caps I2 and I5 which may be substituted for the caps shown by unprimed reference numerals I2 and I5 in Figs. 1 and 2, to form a curling rod adapted for operation in conjunction with a holder provided with a detent, and therefore requiring a ratchet. The cap I5 again may be made integrally of a stamped or drawn piece with a rib 32 corresponding to the rib 32 shown with the cap I5 in Fig. 2. This results in a structure having the apertures 33' and 34' for holding the cap (ratchet) and the handle on the corresponding end of the central curler section II, as previously described. The only difference between the cap I5 and the cap I5 is that the former is somewhat larger and is provided with teeth forming a ratchet, as shown.

Inasmuch as the ratchet wheel formed by the cap I5 cooperates with a detent on the holder, it is not necessary to have an internal spring means acting in the nature of a ratchet as described with reference to the previous embodiment. The journal and barrel I3/2I are therefore omitted. The cap I 2 is substituted for the cap I2 of Figs. 1 and 2, forming a simple circular bearing or journal projection I 3 in place of the polygon l3. The cap l2 of Fig. 3 is attached in press-fit engagement with the left end of the tubular central curler section II in the same manner as previously described in connection with the cap I2.

The caps l2 and I 5 or, in the alternate embodiment, the caps I2 and I5 may be secured in place by press-fit engagement as described, and this engagement may be made more secure, if desired, by upsetting or swaging the caps at one or more points so as to establish a firm connection with the rod II.

The embodiment of the curling rod comprising the members shown in Figs. 3 and 4 and, of i course, the handle 16 and the central section II between the caps l2 and I5 operates exactly as the one shown in Figs. 1 and 2 so far as the winding of the strand of hair is concerned. The tightening of the strand of hair is, however, accomplished by the ratchet coacting with a suitable detent.

In either embodiment the curling rod is made of individual parts which are produced by stamping, drawing or rolling operations. The machining which is necessary when the curler rod is made of an integral piece is substantially eliminated, resulting in considerable saving in the cost of labor. The new curling rod also saves material and, depending on what type of material is used for the individual parts as compared with a solid machined curling rod, can be made lighter. The invention gains importance in view of scarcity of materials such as aluminum from which the machined curler rods were formerly made. Other materials, for example, stainless steel or the like, may be used for making the stamped, drawn or rolled parts. The term stamped or stamping, as used herein and in the appended claims, is intended to denote stamping as well as drawing or rolling operations.

The drawing shows certain'embodiments for illustrative purposes only, to teach others how the invention may be realized in practice. Changes may be made in details and in the assemblage of parts, within the scope and spirit of the appended claims, wherein I have defined what I believe is new and desire to have protected by Letters Patent of the United States.
