SAFETY-PIN.

Specification of Letters Patent.

Patented June 29, I915.

Application filed May 16, 1912. Serial No. 697,725.

To all 107mm it may concern Be it known that I, GEORGE M. LANE, citizen of the United States, residing at Lanoka, in the county of Ocean and State of New Jersey, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

This invention has relation to safety pins, and has for its object to provide means for adding rigidity or stiffness to the pin in order that its parts may not bend or become distorted when engaged with material and subjected to strain.

While the features are shown and described in conjunction with a safety pin, the same features may be advantageously applied to straight pins or pins of any other type and in which the same advantages will be had.

With this object in view the invention consists in providing the work engaging portion of the pin with grooves or depressions at which points the metal of which the pin is composed is compressed, thereby adding rigidity and stiffness to the pin.

A still further object of the invention is generally to improve this class of devices so as to render them more useful and commercially desirable.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure l is a side elevation of one form of the pin; Fig. 2 is a. side elevation of another form of the pin; Fig. 3 is a side elevation of still another form of the pin; Fig. 4 is a side elevation of still another form of the pin; Fig. 5 is a transverse sectional view of the pin out on the line 55 of Fig. 2; Fig. 6 is a transverse sectional view of the pin out on the line 66 of Fig. 3.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

As illustrated in the accompanying drawing in Figs. 1 to 4, incl., wherein a safety pin is shown, the back 1 is connected with the pointed portion 2 at one end by means of the usual resilient coil 3. A head 4; is car-- ried at the opposite end of the back 1 and is adapted to receive the extremity of the pointed portion 2 in the usual manner.

In the preferred form of the invention, which is that shown in Fig. 1, the back 1 and the pointed portion 2 are provided with alined depressions 5 and 6. sions 5 are spaced from each other and the depressions 6 are spaced from each other, but the depressions 5 are formed in the sides of the said parts approximately at right angles to the depressions 6 and the depressions 6 bridge the spaces between the depressions 5 and vice versa. The act of forming the depressions 5 and 6 compresses the material about the sides of the depressions so that rigidity is added to the parts of the pin which will tend to prevent the same from bending when subjected to strain.

In the form of the pin as illustrated in Fig. 2 the back 1 and pointed portion 2 are provided with depressions 7 which are approximately coequal with the lengths of the said back portion and pointed portion.

In the form of pin as illustrated in Fig. 3 the back portion 1 is crinkled or corrugated as at 8 in order to add still more rigidity to the said part.

In the form of the pin as shown in Fig. 4 the pointed portion 2 is provided at that end which joins with the coil 3 with a shoulder 9 which is adapted to prevent the material into which the said pointed portion is passed from entering between the convolutions of the coil 8.

From the above description it will be seen that a pin is provided in which its body portion or its part which is inserted in the material is stiffened by reason of the presence of the depressions formed therein by compressing the material of the part which bounds the depressions and therefore the pin when inserted through material is not liable to bend out of its original shape.

Having thus described the invention, what is claimed as new is:

1. A pin having a back portion and a pointed portion connected by a spring coil, the back portion being crinkled throughout its entire length and provided with longitudinally extending depressions, formed to correspond to the crinkling of said portion.

2. A pin having a back portion and a pointed portion connected by a coil, said portions being formed from cylindrical wire, the back portion being crinkled throughout its length and compressed at diametrically opposite points to provide depressions extending longitudinally of the back portion.

3. A safety pin including a back member The depresentire length and provided With longitudinal depressions formed to correspond .to :its crinkling.

5. A safety pin having a back portionand a pointed portion connected by a spring coil, the back portion being crinkled throughout its entire length and formed With depressions to correspond to thecrinkling of such portion and the pointed portion being reinforced.

6. A pin having a back portion and a pointed portion connected by a coil, said portions being formed from cylindrical Wire, the back portion being reinforced, and the pointed portion being compressed at diametrically opposite points to provide straight longitudinally vextending depresvsions.

In testimony whereof I affix my signature in presence of two Witnesses.
