1 Claim. 1

This invention has reference generally to improvements in that class of inventions known as buttons and clasps and more particularly relates to a safety clasp.

The invention has for one or its objects the provision of a clasp for use in connection with a pin shank of an article of jewelry such as an earring, ornamental pin, or the like, and is adapted for application to the sharpened head of the pin in such manner as to be latched there on with a view of preventing loss of the pin.

It is another and equally important object of the invention to construct a safety clasp in such manner that when engaged on the sharpened point of the pin the latter is covered so that it cannot stick or injure the wearer.

Other objects as well as the nature, characteristic features and scope of the invention will be more readily apparent from the following description taken in connection with the accompanying drawings and pointed out in the claim forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a developed. plane of the clasp prior to assuming its actual shape,

Figure 2 is an elevational detail of the pin, the shank of which is provided with a sharpened head and adjoining neck,

Figure 3 is a sectional view through the clasp showing the parts in position as the pin is being engaged, the pin being shown in elevation,

Figure 4 is a similar view showing the arrangement of the clasp after it has been applied to the pin, and

Figure 5 is a perspective view of the arrangement shown in Figure 4.

Similar characters 01 reference are employed in all the above-described views to indicate corresponding parts.

Referring now, more particularly, to the drawings, there is provided the improved clasp which is preferably formed from a single strip of stiff, flexible material such as metal, and comprises a medial portion I and

terminal tongue portions

2 and 3 continuing therefrom and provided with

curved projections

2 and 3 continuing from the upper edge of the tongue 2 and the lower edge of the tongue 3. The medial portion I is bent upon itself to provide the ring while the

tongues

2 and 3 are bent inwardly and transversely of the ring and arranged in juxtaposed relation with each other. The

tongues

2 and 3 are respectively provided with apertures it and 5 situated out of alignment with each other. Preferably, as shown in the drawing, the aperture 4 is arranged slightly above the medial longitudinal axis of the strip while the aperture 5 is arranged slightly beneath or to the other side of the longitudinal medial axis. The ring is further additional opening 6 positioned opposite the openings in the tongues while that portion of the provided with an 2 ring at the other side of the tongues opposite the opening 6 acts as a guard for the purpose that will be apparent.

The device is particularly applicable to a pin 1, one end of which may constitute an earring or other ornamental pin, and includes a pointed end 8 and an adjoining reduced neck 9, the arrangement being such that when pressure is applied to the curved projections 2' and 3' on the

tongues

2 and 3 the latter are moved relative to each other so that the openings align, the pointed end of the pin being passed through the opening 6 through the aligning openings, and when pressure is released the openings 4 and 5 embrace the neck to prevent accidental disengagement and loss of the pin. It is apparent that when in the position shown in Figures 4 and 5 the portion of the ring adjacent the pointed head of the pin acts as a guard to prevent the pointed end from sticking or injuring the wearer.

It is also apparent that when the pin is to be released it is only necessary to again exert pressure on the projections on the tongues, for instance vertically as shown by the arrows in Figure 3, to align the openings in the tongues, which will permit disengagement of the pin.

It is believed in view of the present description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise, it is believed that the advantages of the invention will be readily apparent.

Having thus fully described the invention, what is claimed as new and desired to be secured by Letters Patent is:

A safety clasp for use with a pin having a neck and a sharpened head including a resilient open ring, apertured tongues continuing from the ends of the ring inwardly and transversely of the ring and arranged in juxtaposed relation with respect to each other and with the apertures slightly out of alignment with respect to each other, one portion of the ring opposite the apertures acting as a guard and the other portion having an aperture for receiving the pin, and projections integral with and extending from the upper edge of one tongue and the lower edge of the other tongue whereby when pressure is exerted thereon the tongues are moved to register the apertures therein so that the sharpened head may pass therethrough and be arranged behind the guard portion of the ring while when pressure is released the apertures in the tongues engage the neck and prevent accidental release of the pin.
