V. CASERTA Nov. 17, 1953 PIN CURL CLI P Filed March 21, 1952 Snventor (Ittornegs Patented Nov. 17, 1953 UNITED STATES PATENT OFFICE PIN CURL CLIP Victor Caserta, Bridgeport, Conn. Application March 21, 1952, Serial No. 277,813
This invention relates to a pin curl clip and has for an object to provide such a clip of an improved and simplified construction which may be easily applied to a pin curl and which will hold such a curl in the most effective position for proper drying of the curl and maintaining its shape.
Another object is to provide such a pin curl clip which may be readily and easily applied to the curl without injuring the hair or forcing the hairs of the curl out of position in the applying operation, and thus the curl is held during drying in proper shape and without being distorted.
A further object is to provide a pin curl clip which while properly holding the curl permits circulation of air for proper and rapid drying of the hair.
With the foregoing and other object in View, I have devised the construction illustrated in the accompanying drawing forming a part of this specification. the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.
In this drawing:
Fig. 1 is a top plan view on an enlarged cale of the preferred form of the pin curl clip;
Fig. 2 is a side View thereof;
Fig. 3 is a bottom view, and
Fig. 4 is a top view showing a somewhat modified construction.
Referring first to Figs. 1, 2 and 3, the improved clip comprises a single strip or piece of resilient spring material, such, for example, as metal or other suitable material, which is bent upon itself intermediate its ends, preferably at substantially its midlength, to provide front and rear portions or arms 5 and 5 respectively. The front arm 5 may also be called the outer arm and is provided with a widened body portion, while the rear arm 5, which may also be called the inner or base arm, is substantially flat and straight and preferably of substantially uniform width throughout. By bending a single piece of the material the front and rear arms are connected by a curved bend l, and as the front arm 5 in the normal position is closely adjacent and on the front surface of the rear arm 6 it is connected with the bend l by an inclined substantially straight portion 3, preferably inclined to the rear arm =3 at an angle of about forty-five degrees.
The body portion of the front or outer arm is widened as indicated at 9 and has gradually and convexly curved outer longitudinal edges it gradually running into the edges of the bend I It is, however, to be understood as indicated at I I, and also gradually curving into a narrower front end portion l2 as indicated at t3, the sides of which portion l2 may be somewhat concaved as indicated at l2a. The'front end portion [2 is curved forwardly and outward- 1y away from the rear arm 6 as indicated at M, providing an open tapered entrance throat or opening 15 for entrance of the hair of the curl between the front and rear arms 5 and 8. With this curved shape the lower surface it gradually runs into the lower surface of the front arm 5 and the upper surface of the rear arm 6 so as to become tangent to these surfaces at the entrance point, and therefore will guide the hair of the curl most effectively, evenly and easily into position between the front and rear arms when applying the clip to the curl, and with the least displacement of the hairs of the curl, and thus with the least liability of deforming or spoiling the form of the curl. The free ends of both the front and rear arms 5 and 6 are rounded as indicated at I1 and I3 respectively, and all the edges are made smooth, even and free of burrs so that the clip will slide easily onto the curl Without danger of the hair catching on any uneven surfaces to be torn or forced out of position.
The widened or body portion llis open, or that is, provided with one or more longitudinally extending elongated openings I9. In the form of Fig. 1 there are two of these openings leaving, a longitudinal narrow bar 28 between them, and this structure provides curved narrow side bars 2! between the openings and the outer curved edges Ill. In the form of Fig. 4 the clip is the same as that of the first form except that the central bar 20 is omitted, leaving only one elongated opening 22 between the narrow side bars 2i. However, the form of Fig. 1 with the central bar is preferred because this bar keeps the hair of the curl from coming up in the middle and. holds it more nearly to proper shape, although the form of Fig. 4 permits greater circulation of air for the drying operation.
In using the device and in applying this clip to a formed curl, as the curl is held the clip is slipped over this curl so that the rear arm 6 is at the under side of the curl next to the scalp and the outer or front arm 5 is against the outer side of the curl. The clip is simply slid onto the curl, the hair readily entering through the inclined throat or opening I5 to a position between the arms 5 and 6, these arms of course separating sufliciently under the resilient and flexible action of the material of which the clip is formed, and after the curl is in position between the arms it is held in proper shape by clamping action of these arms, and it is retained in proper shape during the drying of the hair. Due to the gradual curve of the side edges l3 and I0 and the rounded ends I! and IS, the clip slides easily and gradually onto the curl without forcing the curl out of shape or in- Jurlng the hair. The rounded shape and curves of the clip keep the curl, which is also rounded, flat to the head. As previously indicated, the central bar keeps the hair from coming up in the middle and therefore maintains the proper shape of the curl. The front portion l2 and arm 6 are relatively broad so that it is easy to catch most of the hair of the curl at the start when inserting the clip, and as previously indicated, the clip is so constructed, particularly because of the gradual curve I6 and the shape of the entrance throat or opening l5, that the hair slides easily into the clip. The narrow edge portions 2| of the widened body portion on the opposite sides of the open central portion help to pin or hold down the curl around the edges of the clip and retain it in proper shape during the drying operation. Because of the gradual curved shape and construction of the clip it is a readily removed irom the curl after it is properly dried, without distorting or forcing it out of shape.
Although the dimensions of the clip may be varied as found necessary or desirable, substantially the following dimensions are preferred: that is, the total length of the strip before being bent is preferably approximately 4%, and the bend I is substantially half circle and about A" high, with the inclined portion 8 at about 45 degrees to the rear arm 6. The bars 2| are preferably about 1;" wide and the bar 20 about with the width of the wider portion 9 about and the total length of the clip when formed about 1%". The end portion 12 and rear arm 6 are preferably about wide, and although these dimensions as indicated may be varied somewhat as found desirable, these are approximately the preferred dimensions and have been found to be very satisfactory in the use of the device.
Having thus set forth the nature of my invention,Iclaim:
1. A pin curl clip comprising a single strip of resilient spring material bent upon itself intermediate its ends providing connected inner and outer arms, the inner arm being substantially straight and of substantially uniform width, the outer arm being closely adjacent the inner arm and including a widened intermediate portion having convexly curved outer side edges running gradually into narrower portions at its opposite ends, said widened portion comprising laterally spaced narrow side bars at its opposite edges and a narrow central longitudinal bar between and spaced from the side bars forming longitudinal elongated ventilating openings therewith, and the reduced free end portion of the outer arm being inclined outwardly away from the inner arm forming a tapered entrance throat therewith for insertion of a curl between the arms.
2. A pin curl clip comprising a single strip of resilient spring material bent upon itself intermediate its ends providing connected inner and outer arms, the inner arm being substantially straight and of substantially uniform width, the outer arm being closely adjacent the outer side of the inner arm and including a widened intermediate portion including outwardly and convexly curved laterally spaced narrow side bars and an intermediate longitudinal narrow bar between and spaced from the side bars torming elongated longitudinal ventilating openings therewith, and said outer arm including a reduced free end portion curved outwardly away from the inner arm forming a tapered entrance throat therewith for insertion of a curl between the arms.
