HAIR CURLER William Huppert, New York, N. Y., assignor to Deiamere Company, Inc., a corporation of Delaware Application May 23, 1936, Serial No. 81,371'

4 Claims. iCl. 132-41) This invention relates to a hair curler of the type comprising a form around which the hair may be wound and a wire loop for clasping the hair wound thereon, the bight of the loop, in its closed or clamping position, engaging the end.

of the form. Curlers of this type are generally provided with a pivotally connected finger which is adapted to be pressed down against the form,

either with or without spring pressure, to clamp the. hair ends on the form prior to winding.

An example of this type of curler is illustrated and described in Patent No. 1,739,301 of December 10,1929 to Abraham Goodman and Jacob Goodman. Heretofore the loop element of such curlers has been formed with two inturned ends, which ends extend inwardly through holes in the curler. In order to prevent the loop from becoming disengaged, the ends, after insertion in the curler, are upset or bent upwards.-

This bending necessitates a further operation and is objectionable because it tends to vary the radial length of the arms of the loop with the result that in some cases the loop is too short properly to engage the end of the curler, and, in other cases, it is too long. In either case the defect must be remedied before the curler becomes' a commercially salable article. These curlers are manufactured in very large quantities to be sold at a low price and hence all additional operations tend to increase the cost of manufacture of the article.

My invention aims to overcome these objections by the provision of a wire loop which is so constructed that it may be easily assembled with the curler and that when so assembled it has a substantially definite fixed radial length of such dimension that the bight of the loop, in its closed position, will properly engage the end of the curler.

Other objects and advantages of the invention will appear from the following description thereof, reference being had to the accompanying drawing, in which:--

Figure 1 is a plan view of the wire loop element of the curler;

Fig. 2 is a side view of one form of the curler;

Fig. 3 is a view of the same, partly in section, taken on the line 3-3 of Fig. 2;

Fig. 4 is a vertical sectional view taken on the line 4-4 of Fig. 2; and

Fig. 5 is a similar vertical sectional view showing a modification.

The wire loop element indicated generally by the reference character It is made-of a single length of wire bent to form two side portions or or bight l2, Each of the two ends of the wire 'as fulcrums on which the loop turns or swings" sures uniformity in bending the wire into proper to the length from the hole l8 to the front end of the tube l5 so that when the loop is swung arms II, which arms may beslightly bowed outwardly as shown, and a connecting end portion extend inwardly in a relatively short portion i3. and terminates in a quadrantal or arcuate shaped 5 portion ll of small radius. The radius of curvature of the portion is such that a tangent to the curve will form-anacute angle with the arm II, as indicated by the angle X in Figure 1. The extremities of the two curved portions are direct- 10 ed toward each other. The portions l3 function while the curved portions it provide means for preventing accidental disengagement of the ends when they are inserted in the curler. It is an 115 essential feature of my invention that the inturned ends of the loop be preformed or prebent in substantially the form just described, that is to say, the ends of the loop are bent to shape before they are inserted into the curler and not afterwards. The loop may be conveniently formed in the desired shape in a die. This aspredetermined shape. Preferably, all of the parts of the loop lie in a single horizontal plane.

The curler in the particular form shown in the drawing comprises a slightly conical tubular member I5 and a semi-tubular clamp arm 16 adapted to lie on or press against the member l5. The arm l6 has ears II, which ears have holes l8 that aline with corresponding holes IS in the tube ii for reception of the inturned ends of the loop element l0.

The radial length of the loop member, indicated as R in Fig. 1, that is, the length from the inturned portion or fulcrum ltjto the cross piece or bight I! of the loop, may be substantially equal down to its closed or hair clasping position, as 40 shown in Figs. 2 and 3, the bight of the loop will engage the end of the curler with sumcient tension to hold it in place against accidental dislodgment but not sumciently tight to prevent itfrom being easily unfastened when it is desired to take the curler out of the hair. If desired, the end 20 of the tube i5 may be provided with shallow notches 2| in which the bight oi the loop engages in closed position. The bowed. form of the arms of the loop give the loop suflicient resiliency so that it may readily be swung into or out of engagement with the end of the form.

In the form of curler illustrated in Figs. 2 to 4, inclusive, the prebent inturned ends of the loop serve to connect the elements l5 and I6 pivotally the two members I! and II at their point oi pivota1 connection.

In assembling the curler, the prebent ends of the loop are inserted through thealined holes l8 and I9. In doing this, one endis inserted first and then the other. The radius of the curvature of the curved portions l4 oi the end of the loop is such that they may be easily inserted through the holes in the tubular and semi-tubular members and held in place within the tubular member against accidental disengagement; and that the loop may be swung freely about its axis without having its inturned ends bind against the bore of the tubular member.

While for the purpose of illustration I have shown the loop element applied to one form of curler, it is to be derstood that I do not limit my invention in s respect as it may be applied to other known forms, and that various modifications in the details of the loop element may be made within the scope of the invention.

What I claim is:--

1. A hair curler comprising a tubular body and a wire clasp swingably secured to the body, said clasp having spaced apart side portions interconnected at one end and terminating at their opposite ends in preformed curved portions that are directed toward each other and extend into the tubular body to prevent accidental detachment of the clasp and to permit of swinging it rel? atively to the body through an are having a radius of predetermined length.

2. A hair curler comprising a tubular, body and a wire clasp swingably secured to thebody, said clasp having spaced apart side portions interconnected at one end and terminating at their opposite ends in preformed portions of reverse curvature that are directed toward each other and attend into the tubular body to prevent accidental detachment of the clasp and to permit of swin ing it relatively to the body through an are having aradius of predetermined length.

3. A hair curler comprising a tubular body, a clamping member hinged to the body, and a wire clasp swingably secured to the body, said clasp having preformed inturned curved ends that extend into the body to secure the clasp swingably to the body against accidental detachment.

4. A hair curler comprising a tubular body, a clamping member hinged to the body, and a wire clasp swingably secured to the body, said clasp having preformed curved ends that are directed toward each other and extend into the body at the point oi hinging of the clamping member to secure the clasp swingably to the body against accidental detachment.
