They the type comprising two pivotally connected have substantially parallel arcuate portions [4 jaws for use in waving hair. Devices of this between which hair may be gripped when the clip type are provided with handles or ?nger pieces is in its closed position, diverging handles or ?n for manipulating the jaws and a spring for press ger pieces I5 along the middle, portion of their ing the jaws together. upper edges for manipulating the jaws, said han Heretofore the jaws have generally been piv dles having overlapped ears “5 and I1, diverging otally connected by a separate pin that extends ?anges l8 along the length of the lower edges of through openings in overlapping ear portions of the portions Hi, and teeth 1 9 on each jaw ex the handles, and are provided with a coil spring 10 tending inwardly at an angle to the ?ange, the mounted on the pin with its ends bearing against teeth of the two jaws being interspaced, with those on one jaw lying substantially parallel to the handles, as disclosed, for example, in Patent No. 2,040,807, of May 12, 1936, to A. Goodman. the flange of the other in closed position. The The operation of assembling the parts of such parts above described are all more or less com hair wave clips has been relatively slow and 15 mon in hair wave clips of this type. tedious. The ears of the two jaws had ?rst to According to the present improvement the ears be lined up, then the pivot pin inserted through it‘ of one handle, preferably the inner of the over the aligned openings in the ears and through the lapped ears, are each formed with a short cylin center of the coil spring, and ?nally the pin had drical stud or boss 23 that projects outwardly and to be headed to prevent its withdrawal. ?ts into a corresponding opening 2| in the ears Furthermore, with use of a coil spring the ll of the other handle, whereby the two handles spring tension is not distributed throughout the are pivotally connected together. While I prefer length of the handles but only in a restricted to form the studs on the inner of the overlapped area. This is particularly objectionable in the ears and the openings in the outer ones, the rela case of Wave clips made of molded plastic ma 25 tionship may be reversed. The spring element l3 may be made of a single terial since in some instances the handles tend to become deformed in time with a resulting un piece of spring wire bent to form two substan sightly appearance. tially parallel legs 22 and a connecting leg 23. It is an object of this invention to provide an While the spring is preferably of Z or S shape, improved hair wave clip that can be easily and 30 it may be of any other suitable shape having sub stantially parallel leg portions 22. rapidly assembled without use of a separate pivot pin. The legs 22 are received in grooves 24 formed Another object of the invention is to provide in the inner faces of the handles [5, and, as seen in Fig. 2, they extend throughout substantially a construction wherein the spring element bears against the handles throughout substantially 35 the entire length of the handles, thus distribut their entire length. I attain these objects, as well as others, by ing the spring pressure over the length of the handles. The overall width of the spring is greater than the spacing between the grooves of means of the construction hereinafter described and illustrated in the accompanying drawing in the two handles. By merely compressing the which: 40 spring it may be easily snapped into place in the grooves.
