Safety Pin, of which the following is a" specification.

This invention relates to safety pins: of a well known form, wherein a single length ofv spring wire is coiled upon itself'at its-midlength, and has one end sharpened and adapted to engage and be shielded by the other end of the vWire. when an extra heavy strain comes upon the clothing fastened. together by this pin, the

pin-portion receives a permanent bend which:

not only badly alfectsthe, appearance there'- 1 of, but rendersthe pin-point liable to withdrawal from the'shielded end and thereby to fail in its attaching function.

The main caus for such bending of at, pin I find-to be due to the unyielding action f of the shield-carrying portion of the device, the same being so inflexible as-to force all the fiexure to be performed by the pin-sec tion alone. p

To remedy this, I have devised means for rendering the shielding section of the safety.

pin quite flexible, this being preferably done b 1 formin the sectlon with several helical invented other means for giving the desired flexibility, as by flattenlng the shielding section to lie in a planeat right angles to the plane of the two pin-sections, or by givlng the wire numerous zig-zag bends, yet the preferre'd arrangement appears togive the best results, and at the same time provides a convenient means for stitching the safety pin to a garment when so desired. I

In the drawings forming part of this speci fication, Fig. l is a side view onan enlarged provements. Fig. 2 is a top view of the same. Fig. 3 illustrates a modification of the shielding pin portion. Fig. 4 1 s another As shown in Fig. 1, the safety pin consists of a length of spring wirebentat its mid-- length to form a coil 1, and having its pin section 2 sharpened in the usual way and engaging the. shield 3 held by the other poi--- tion 4 of the wire. w v I The portion 4 of the'wire is formed With several coil's 5, preferably made helical and then bentover to lie oneagainst the other,

as illustrated in Fig. 2. Thus made, the

lieve the bending strain otherwise put 'upon the pin section 2. I have observed that 'In-additionto this flexibility given to the back 4;,the coils 5' provide eyes through which to pass stitches into a fabric to which it may be desired to attach the pin.

These eyes being located at themidlength back sis rendered sufficiently fiexibleto re of the back 4 and of,the:safety fpin, the

stitches through the same will properly balancethe pin in its suspension action.v lathe-construction illustrated in Fig. 8,

the back isv seen to be'flattened for giving it theflexibility desired. While this requires? Y a less wire for .itsfmanufacture itjdoes not provide the eyes suitable forstitching the pin to a fabric;
