CURLING IRON.

Application filed November 17, 1922. Serial No. 601,630.

To all whom it may concern:

Be it known that I, WILLIAM A. RANKIN,

a citizen of the United States, residing in Oak Park, county of Cook, State of Illinois,

have invented certain new and useful Im arovements in Curling Irons, of which the Iollowing is a specification.

My invention relates to curling irons and has for its object theprovision of improvements in curling irons, particularly in connection with the operating means for the clamping members,

IVith the usual type of curling which the clamping members are together in the manner of the jaws of a pair of tongs, it is often necessary to move the clamping members almost, if not wholly, to wide open position before the hair is released. Also therhair has a tendency to catch at the pivot. In carrying out my invention, I have provided operating means for the clamping members whereby the hair may be quickly and effectively released. In one form of my invention I have provided iron in operating means whereby the clamping memtion to each other. My invention also com-' prchends a releasable connection between the two clamping members whereby the cylindrical clamping member may be used alone or in conjunction with other appliances.

For a better understanding of my invention reference should be had to the accompanying drawing in which Fig. 1 is an elevation view of a curling ironembodying my invention; Fig. 2 is a view similar to Fig. 1 showing the various positions of the clamping member; Fig. 3 is a partial vertical section view of Fig. 1; while Fig. 1- is a partial perspective view showing one clamping member partly removed.

Referring to the drawing, I have shown my invention as applied to an electric curling iron, although it obviously has applica tion to various other types of curling irons. In one form of my invention I employ an elongated, cylindrical, heated member 10 forming one of the clamping members of the curling iron and provided with a handle 11. The member 10 is provided inits interior with a suitable electric heating element (not shown) the terminals of which are brought out, ferexam le, in a socl: and of the handle whereby the bee.

pivoted member.

" in the ment may be connected through a suitable attachment plug 12 to a source of electrical supply.

Cooperating with the cylindrical member 10 is a clamping member 13 having the usual concave convex section and extending longitudinally of the cylindrical member so as to partially surround the cylindrical ment ber when in engagement therewith. vThe clamping member 13 may be lifted by means of an operating member 14, shown as a lever, to the right hand end of which the clamping member is pivotally secured by a pivot 15 near the left hand end of the clamping member, the operating member having a pivot 16 on uprights or ears 17 carried by a metallic sleeve 18 fitting loosely on the cylindrical member 10. The sleeve18 carrying the operating lever 14: and the clamping member 13 may be slipped off the cylindrical member 10 to provide for the use of the cylindrical member alone or for the attachment to. the cylindrical member of other appliances, such as a comb.

When in normal operating position, as shown inFigs. 1,2 and 3, the left hand end of sleeve 18 is inserted for a short distance in a locking member 20 in theform of a sleeve secured in the handle 11 and surrounding the cylindrical member 10, the

member 20 being countersunk to receive the end of sleeve 18. The member 20 is provided with a longitudinal recess 21 1) with which a projection 22 on the sleeve 18 is adapted to register, whereby the, sleeve is held against rotation on the cylindrical An annular locking groove 23 is also provided on member 20, and the lower end of a coil spring 24: surrounding pivot 16 rests in this groove, thus releasably secur ing the sleeve 18 against longitudinal movement on the cylindrical member. The upper end of spring 24 rests against the left hand end of operating lever 14 so as to force this end of the lever in an upright direction and hence bias the clamping member 13 into engagement with the cylindrical member 10; As shown in the drawing, the spring 2 1 is formed of a doubled length of'wire so that the two ends are uppermost and rest against the operating lever 14:, while [the lower end of ,thespring is in the form of a loop havinga short transverse arc shaped portioii25 which seats in the groove 23. The spring theretare performs the double member and biasing the clamping member into engagement with the cylindrical member. Preferably theleft hand end of the cylindrical member adjacent the handle 11 is slightly enlarged so as to fit the sleeve 18 snugly at this point whereby the sleeve is secured firmly in place.

The clamping member 13 is provided with an -extension 26' forming the left hand end of the clamping member 13 which extension lies between the supporting cars 17 and below pivot 16. I Normally the left hand end of the clamping member-is held against the projection 22 by the ofs'orin 21 a) slied throu h the o Jera n 1. b t) C arm 1 1 to the pivot 15 of the clamping member, the right hand end of the clamping member being held at the same time in clamping relation with the cylindrical member 10, as shown in Figs. -1 and As the left handend of operating lever ii. is depressed the'left hand end of the clamping member is lifted first due to the overbalano ingaction ofthe greater weight of the portion of the clamping member to the right of pivot 15, The left hand end ofthe clampingmember is thus raised until eX- tension 26 engagespivot-lG or the coils of the-spring 2% surrounding the pivot, whereupon-the right hand end'of the clamping member is lifted- To provide for this upward movement of extension 26 the lower end of spring 24 is providedwith a lateral downturned portion. It will" be observed that after the extension 26 engages pivot 16 the clamping member moves with the operating lever-so that the two move together about the pivot 16. lVhen the clamping member 13 has been moved about pivot 16 to fullopenposition, the'extension' 26 engages witlr the upwardly extending right hand end of projection 22 on sleeve 18, as shown iii-dotted lines-in Fig. 2, whereby a further-opening movement of the clamping member is prevented. The projection may be' made of-any height according to the amount ofopening desirech Obviously, the'opening of the clamping member may also-be limited by suitably regulatingthe length of the clampingmember to the left (if-pivot 15 or, in other words, the'length of extension 2G, in which case the projection or stop 22 may be adapted only to fit in recess 21 so as to hold sleeve 18 against rotation. A suitable button 27 is provided on the left hand end of-the operating lever t whereby theoperatinglevermay be con vcniently depressed by the thumb of the operator in a well known manner;

As. thus constructed and arranged, upon depressing button 27 to remove the curling iron-from the hair the inner end of the clamping member 18 is lifted a short distance before the outer end due to the overhanging weight of the outer end. This action sures the complete release of the hair-at this point, thus preventing the atching and pulling of the hair common with the usual typeof curling iron having its a pivoted in the fashion of a pair of tongs. After the inner end of the clamping member 13 engages pivot 16, the outer end is lifted so that the clamping member may be caused to assume a position parallel with the cylin drical member 10 and spaced a predetermined distance therefrom as shown in Fig. 2. Ample space may be provided when the jaws are in this parallelrelation to permit the free removal of the hair from the clamping members, The hair may therefore be completely released to permit its removal by only a smalldepression of button It will be observed that the clamping member 13 is thus initially given a movement of translation to this parallel position. Upon fi'irther depression of button 27 the clampin member is moved to full open position about pivot 16, as previously described. lVhile I have described my invention as embodied in concrete form and as operating in a specific manner in accordance with the provisions of'the-patent statutes, it should be understood that I do not limit my invention thereto, since various modifications thereof will suggest themselves to those skilled in the art without departing-from the spirit of my invention, the scope of which is set forth in the annexed claims.
