The device, in these various modifications, comprises the usual tubular member or form It] and semi-tubular member or finger 1! common in the manufacture of curlers of this type. These parts may be made of metal or molded plastic material. If desired, the semi-tubular member H may be omitted. The device also preferably comprises a wire loop clamping member I2 which differs, however, from the usual wire clamp in that its ends are preferably Welded or connected' together at I 3, as best seen in Fig. 21, prior to the assembly of the loop with the other parts of the curler.

A springless type of curler, having metal tubular and semi-tubular members, is shown in Figs. l-G, inclusive. Each of these members has a pair of opposed openings or perforations l4 and I5, respectively, near one end, and slits it and ll, respectively, leachng from the exterior to the corresponding openings. The metal at the slits is bent out of its normal plane to provide an open passage of greater width than'the diameter of the wire of the loop I 2 through which, when the two members are assembled, the closed loop !2 may be freely passed into the aligned openings. The bent parts are subsequently rebent into their normal plane to close the passage and to confine the loop in the aligned openings 14, I5.

It will be observed that the loop is fulcrumed in the openings toswing over and around the tubular and semi-tubular members and that those members are pivotally connected together by that portion of the loop that passes transversely through the openings and serves as a pin about which the members pivot. The outer end of the loop may be provided with the usual roller 58 fastening the loop in closed position, although the roller may be omitted and the loop may be secured in closed position in any other known manner. In some forms of the invention the loop may be omitted and a pivot pin may be used for pivotally securing the two members together.

In Figs. '7 and 3 is shown the form of curler in which each of the metal members In and II has a rearwardly extending handle portion l9 between which a spring 20 is disposed for urging the members closed. In this instance, as in the previous described form, each of the members has aligned openings M, iii for reception of the closed loop 12, and slits l6 and I1, respectively, leading from the exterior to the corresponding openings. The slits are opened by bending portions of the metal at the slits, as seen'in Fig. 8, to provide a passage-through which the closed loop member may be inserted into the aligned openings. Th bent portions are then rebent to their normal position to close the passages against withdrawal of the loop.

Any suitable tools or dies may be employed for closing the passages. A form of such tools is shown in Figs. 9-12, wherein Z! is an arbor having a rounded conical head 22 formed with a slot or recess 23. The arbor is inserted and forced into the opening at the rear end of the curler to bend or swage the inwardly bent portions 24 back to normal position. The slot or recess 23 in the arbor provides clearance for the closed loop 12, which as above noted, is placed in the assembly prior to this bending operation. 25 is an outer die having a pair of arms 26 that pass over the outer surface of the assembly to rebend the outwardly bent portions 21 into their normal 'posithere shown, the tubular member ID has a slot 28 leading to the openings 29, and has formed on its external surface recesses 30 in which the tubular member, and lead to openings 33. After.

assembly of the parts, asseen in Figs. 13 .and 14,

portions ofthe material adjacent the slots 32' are pressed out to provide protrusions. 34 that close the slots immediately below the openings. In connection with Fig. 17, there is shown a tool or die 35 for forming the protrusions 34 as shown in Fig. 18. In Fig. 16 the protrusions are indi-.

cated by dotted lines.

A modification of the semi-tubular member is.

shown in Figs. 19 and 20 wherein that member is initially molded with lateral projections 36 that; A tool 31 are pressed down to close the slots 32. for this purpose is indicated by the dot-and-dash lines in Fig. 20.

It will be seen from the foregoing description that the construction of the curler is such that a preformed, completely closed loop may be readily. and easily applied to the curler, and that when the parts are assembled, they will be retained in proper relation to eachother.

While I have described my invention with reference to specific-forms thereof, it will beunderstood that various changes maybe made therein' without departing from the spirit of the invention.

What I claim is: I
