9 Claims.

This invention relates to clips and more particularly to a type useful in nonpiercing earrings.

It is the object of the present invention to provide a clip construction fOr earring which is rugged and economical and which may be worn with comfort and with certainty of retention over long periods of time. I

It is a further object of the present invention to adapt conventional button hacks for the reception thereby of a resilient metallic wire clip to attain a resilient clip assembly which may be worn with comfort upon the earl lobes. The invention comprehends the combination of all types of ornamental surfaces with metallic button backs in accordance with the present invention, so that earrings of all types may be had by different combinations of ornamental fronts with the metallic backs such as ornamental button shells of metal, plastics, fabric or cabochons of all types.

The invention proceeds upon the principle of providing a channel functioning as a pivotal seat for a spring clip by stamping this channel in the button back at one side of the center thereof, which may be executed at the time of manufacture of the button back as a part of the original stamping operation, and which may be sup-- plemented by the stamping of a protuberance at the opposite side of the center of the button at the point of engagement of the end of the resilient clip to obtain a more perfect gripping action between the clip and button back. Ornamental surfaces of all types may be combined with the metal back by spinning an ornamental button shell around the flange of the button back, or by pressing the flange of the button back around the ornamental shell of'metal or around an insert of any other material such as cabochons of all types well known in the jewelry art. A special spring clip of resilient metal wire havin bifurcated arms terminating in inwardly ex tending trunnions is engaged in the pivotal seat formed by the channel by spreading the arms slightly until the transversely extending trunnion extend into the opposite ends of the channel. These ends of the channel are tapered toward each other and towards the center of the button back in order to spreads the sides of the spring clip when the latter is pivoted from the plane of the button back, which spreading of the arms acts against the resilient force of the spring wire material to remain in undistended position, whereupon the release of the pivoting force causes the clip to return to its normal position with the junction end of the bifurcated clip adjacent to the button back.

It is a further object of the invention to pro- Vide an economical clip construction which requires no soldering, or the handling of sealing plastics or complicated spring structures to adapt a conventional button back fo use as'a clip which may be used as an earring or other ornament independent of, or in supplement to, a conventional set of button having similar ornamentation.

Other objects and purposes will appear from the more detailed description of the invention following hereinafter, taken in conjunction with the accompanying drawing, wherein Fig. 1 is a front elevation of a button back in accordance with the present invention;

Fig. 2 is a rear view of Fig. 1;

Fig. 3 is a rear view corresponding to Fig. 2 showing the clip in raised position, at which time it exerts its tendency ,to return to its position shown in Fig. 1;

Fig. 4 is a vertical sectional view along line 44 of Fig. 1 with the clip shown in solid lines in its normal position, and in dotted lines in its raised position;

Fig. 51s a perspective view of the spring clip element which may be used with the button back in accordance with the present invention to complete the economical and rugged assembly;

Fig. 6 is a perspective viewof the finished earring in accordance with the present invention, illustrating an ornamental metallic button shell having the flange thereof surrounding the flange of the metallic back;

Fig. '7 is a perspective view of a different form of the invention showing the applicability of the invention to button backs which are also adapted to be used as conventional buttons; and

Fig. 8 is a perspective view of a button back of a different geometrical configuration showing the alternate adaptability f the back to be used as a button or as a clip.

In Figs. 1 to 4 of the drawing is shown a conventional circular metallic button back 8 which preferably is adapted to be stamped from metal sheeting with a surrounding flange I8 and which, in addition, has a trapezoidal channel 6 stamped outwardly from the rear surface thereof terminating in spaced convergingly directed slits 5 which taper towards the center of the button. This trapezoidal channel is stamped at one side ofthe center of the button back along a chordal line of the circular back and the slits taper towards the opposite side of the center line so that the minor parallel side I-of the trapezoid-is closer to the center of the button back. A bifurcated spring clip I of tempered steel or brass wire, as shown in enlarged scale in Fig. 5, is provided with two arms 2', 3', which terminate in inwardly extending trunnions 2 and 3 and have a common junction point 4. The trunnions 2, 3 are inserted into the channel 6 through slits 5 by a slight spreading of the arms 2 and 3'. Normally the clip tends to abut the button back, and in order to perfect this abutting action, a small protuberance 9 is stamped outwardly of the button back at the same time that the channel 6 is stamped therefrom. The protuberance 9 is disposed equidistantly from the ends of the channel 6 in the vertical center of the button back. Thereupon a more complete and lasting resilient engagement is had between the junction end I of the clip and the button back.

When the clip I is pivoted around its trunnions in the channel 6, as indicated by the arrow in Fig. 4, the arms 2' and 3' move towards the wider portion of the channel by the camming action of the end edges or slits 5 to effect a spreading of the arms. The resilience of the arms is such that a force is exerted to return the clip to its normal position, which is done when the raising force is released, so that the lobe of an ear may be comfortably engaged between the clip I and the button back 8. The clip is so shaped that a partial spacing of the end 4 from the protuberance 9 results in a sufficient space for the accommodation of an ear lobe. Furthermore, the channel 6 is disposed inwardly of the circumference so that no partof the clip is visible when the same is worn, while the extent of clip contact from adjacent one end of the button to the other results in an effective gripping action with maximum comfort to the wearer.

Fig. 6 shows an ornamental button shell II which may be of sheet metal or plastic, having a flange l2 spun around the flange of the button back.

In Fig. '7, is shown a cabochon 13 which may be of plastic, onyx or any other ornamental material, which is adapted to be crimped by the flange I8 of the button back. In this view is shown aswell, a conventional buttonhole channel 20 which may be pressed into the button back in supplement to the channel 6 and protuberance 9, in order that the back may be adapted to alternative uses as a conventional button or as a clip.

'In Fig. 8 is shown a button back I6 of hexagonal configuration having the pivotal channel seat 6 and protuberance 9 stamped therein in supplement to the buttonholes l9, so that the back may be used alternately as a clip or as a button. The invention may be applied as well to button backs of any geometric configuration or design.

It is understood that while the invention is particularly applicable to the adaptability of conventional metallic button backs .to the use of earrings, the features thereof may as Well be applied vention thereto, since various modifications 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.
