SAFETY PIN.

Application filed. Gctober 15, 1924, Serial No. 743,674. Renewed August 27, 1925.

To 055 w/zcm 2t may concern;

Be it known that I, Lnoronn Hoorrnninnn, a citizen of Austria, residing at New York city, in the county of New York andState of New York, have invented certain new and useful Improvements in Safety Pins, of which the following is a specification.

This invention relates to safety pins, the invention having for an object the provision of a novel and improved safety pin that can be more easily applied to and removed from the articles in connection with which it is used. 1

A further objectof the invention is to provide a safety pin that can be readily applied and removed without necessitating the use of two hands, and which will, when in use lie flat on the article to which it is applied.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a face view of my improved safety pin.

Fig. 2 is a face view of the pin, but showing it as in actual use, the opposite face of the pin being shown in Fig. 2 to that shown in Flg. 1.

Fig. 3 is a face view of the pin showing the latter as being withdrawn from the article to which it has been applied.

Fig. 4 is a longitudinal sectional view taken on the line 4 l of Fig. 2.

Fig. 5 is a transverse sectional view-taken on the line 5-5 of Fig. 1.

Fig. 6 is a transverse sectional View taken on the line 6-6 of Fig. 3.

Fig. 7 is a transverse sectional view taken on the line 77 of Fig. 2.

Fig. 8 is a similar View to Fig. 1 but showing a modification.

Fig. 9 is a similar view to Fig. 1. but showing a further modification.

My improved safety pin is constructed entirely from a single length of suitable resilient wire that is pointed at one end to form the point of the pin. This Wire forms two main reaches 10 and 11 that extend parallel to one another, the reach being free at one end and pointed as at 10 to constitute the point of the pin. At the other end of the reach 10 it is united with the reach by a spring element formed by coiling the wire in two turns, the wire being given one turn in the form of a circle 12 while the other turn is projected to one side in the form of a flattened loop 13, the purpose of this laterally projected loop being presently set forth.

The end of the reach 11 that is adjacent to the point of the pin is bent to form a relatively large loop 15 within the confines ofwhich the point of the pin is located. The side of the loop 15 that is located nearer, or toward the

parts

12, 13 preferably extends approximately in a straight line across the reach 10, as at 16 the loop 15 being completed by uniting the end of the wire to the reach 11, as at 17. This transverse member 16 preferably extends at a slightly oblique angle with respect to the

parts

10 and 11 as shown, and it may be joined to the member11 by. coiling its end around the latter. The loop 15 is formed, on the side thereof remote from the reach 11, with an inward projection 19 of generally angular form whose apex is close to the pointed reach 10 when the parts are in normal position. As clearly shown in Fig. 4 of the drawing the loops 13 and Marc bent to lie in planes that are slightly inclined to the plane in which the two main reaches 10 and 11 of the pin lie, the purpose of this arrangement being to assist in causing the pin to lie flat on the article to whichit is applied, as will be presently pointed out.

In applying my improved pin the latter is placed in the position shown in Fig. 1 of the drawing upon the article to, which it is to be applied, the pointed end of the reach 10 being under the transverse member 16 of the loop 15. By pressing downward with the thumb, while the loop 13 is grasped, the point 10 is caused to enter the article and the pin is then moved longitudinally a slight distance, the point being then permitted to emerge from the article. The pin is then twisted upon itself through an angle of one hundred and eighty degrees, causing the transverse member 16 of the loop 15 to be engaged under the reach 16. It will be noted that the lateral projection of the

loops

13 and 15 causes them to remain in this position to which the pin has been adjusted and in which the pin lies flat upon the article, while the angle or inclination above referred to of the

loops

13 and 15 ensures the ends of the pin lying in close contact with the article. It will be noted also that when the pin is applied as above set forth the transverse member 16 engages the article, indicated generally at A, in which the pin is placed it the pin tends to slip out, and thereby prevents such slipping movement. When the pin is to be removed it is swung to its former position (that is to say the position shown in Fig. 1) and then drawn backward. \Vhen the backward movement of the pin starts the projection 19 presses against the article with which the pin is engaged and acts to lift the transverse member 16 free of the latter so that the pin may be readily withdrawn.

In Fig. 8 I have shown a modified construction in which the loop 15 is projected further in a lateral direction and the in ward projection 19 is omitted. In this construction the end transverse element of the loop is formed with an indentation to receive the point of the pin. The parts are otherwise as above described. This indentation 25 might be applied to the construction shown in the other views if desired.

The pin shown in Fig. 9 is identical with that shown in Fig. 1 except that the projection 19 is positioned somewhat differently.

I may, instead of simply inclining the loops at the ends of the pin give the latter a general curvative from end toend.

Having thus described my invention What -I claim as new and desire to protect by Letters Patent of the United States is as follows 1. A safety pin formed of a length of wire bent to form two parallel reaches, said reaches being united at one end in a transversely projected coil, one of the reaches having its other end pointed, the other reach being formed at its other end to present a loop in which the said pointed end engages, the said loop and coil extending at a slight inclination to the plane of the said reaches.

2. A safety pin formed of a length of wire bent to form two parallel reaches, said reaches being united at one end in a transversely projected coil, one of the reaches having its other end pointed, the other reach being formed at its other end to pre sent a loop in which the said pointed end engages, the said loop presenting a transverse inner end member that projects across the first named reach.

3. A safety pin formed of a length of wire bent to form two parallel reaches, said reaches being united at one end in a transversely projected coil, one of the reaches having its other end pointed, the other reach being formed at its other end to present a loop in which the said pointed end engages, the said. loop presenting a transverse inner end member that projects across the first named reach, at a slight oblique angle.

4:. A safety pin formed of a length of wire bent to form two parallel reaches, said reaches being united at one end in a transversely projected coil, one of the reaches having its other end pointed, the other reach being formed at its other end to present a loop in which the said pointed end engages, the said loop presenting a transverse inner end member that projects across the first named reach, the said top being formed on one side with an inward projection extended toward the said first named reach.

5. A. safety pin formed of a length of wire bent to form two parallel reaches, said reaches being united at one end in a transversely projected'coil, one of the reaches having its other end pointed, the other reach being formed at its other end to present a loop in which the said pointed end engages, the said loop presenting a transverse inner end member that projects across the first named reach, the said top being formed on one side with an inward projection extended toward the said first named reach, said projection being of angular form and having its apex adjacent the said first named reach.

In testimony whereof I have 'ar'fixed my signature.
