M. V. ASSAF SAFETYPIN Filed May 10, 1958 INVENTOR.

Patented Apr. 25, 1939 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to safety pins of a wellknown type which are made of a single metal rod or wire so bent that part of the wire forms a fixed member which carries at one end a shield and at the other end is bent around to form a spring coil and from this coil the rest of the wire or rod extends as a piercing member. This piercing member terminates in a sharp point intended to go through cloth or similar material and it is of such length that this pointed end is sprung into and is protected by the shield.

With the usual type of pin, if pressure is applied medially between the fixed member and the piercing member, it may release the point from the shield or may permanently bend parts so that they do not readily function thereafter. Other things that occur are that the shield sometimes is bent outward, releasing the point, and the fixed member and the piercing member are pulled apart, releasing the point. A very serious objection is that when the piercing member goes through the material and the pin is closed, there is a tendency for the fixed member, together with the spring coil and the guard, to stick up, to be unsightly and in the way and in a position to be caught and bent or released.

This pin includes a bow member extending from and preferably bent from the fixed member so as to overlap the piercing member on what I will call the top side, and preferably the coil is bent down so that the piercing member will naturally go under this bend and the shield is closed at the top and open at the bottom so that the piercing member must go in on that bottom side and under the bow. The shield is preferably also provided on the inside with a V-shaped slot and the pointed member is provided with a recess so that when the point is inside the shield, it is locked in this recess, while the bow which extends above and beyond the piercing member resists any pressure and prevents the piercing member from being accidently released.

In the drawings, W represents a continuous piece of wire or rod made of suitable metal bent 4 so as to form what I will call a fixed member F at the free end of which is fastened a shield S made of sheet metal. This shield S is closed at the top 3 and open at the bottom 4. It has no tongue and on the inside is provided with a V- shaped slot 6. 25.

Member F is bent near the middle to form a triangular-shaped bow B.

At the other end of member F, the wire is bent down around to form a spring coil C at the bottom instead of at the top so that when it is extended as a piercing member P, that member will go under the bow B and will be in a position to pass through open bottom 4 into the shield S. The free end of piercing member P is formed as a sharp point l5 and behind this is a recess l6 adapted to slip into the V-shaped slot 6 when the pin is closed.

A represents the cloth and a piercing member P goes through the cloth while the bow B is at the top and extends over P, and as the shield S is flat and the coil spring C is also flat, when tension is put on the cloth, all these factors cause the fixed member F to lie down flat on the cloth.

Besides this, as the closed part 3 of shield S is at the top, there is no chance for anything to catch in it and as the recess l6 locks the piercing member P in slot 6, against any tendency to pull out and the bow B prevents any tendency to push piercing member P towards fixed member F and its point out of the V-shaped slot 6, the pin not only lies flat but cannot be released unless by the operator.

Instead of a single triangular-shaped bow such as B, I can, as shown in Fig. 5, particularly with such large pins as are used with horse blankets, use a relatively heavy wire D bent to form a fixed member 20 at one end of which is a shield 2| and at the other end of which is a spring coil 22 which is extended to form the piercing member 23 and into two relatively narrow bows 24 and 25 which extend slightly beyond and over piercing member 23.

To make sure that the piercing member will always go under these bows, I prefer to have the shield 2| closed .at the top and open at the bottom and the spring coil 22 bent around and down.

In Figs. 8 and 9, I show a pin bent from wire E so as to form a fixed member at one end of which is a shield 3| open at top and bottom and having a center tongue 32 in a well-known manner. Member 30 is bent in the middle to form a relatively circular bow 33, held together by a collar 34, and its other end 35 is merely bent, not coiled. The piercing member 36 has no recess such as IE but can go either above or below the bow and into the top or bottom of the shield.

In Figs. 10 and 11, I show a wire G formed into a fixed member 40, at one end of which is a shield M, and bent in the middle to form a bow 42. At the other end of member 40, wire G is formed as va spring coil 43 bent up instead of down so that the piercing member 44 will be bent or forced under the bow 42 causing a pinching action which, in some cases, may be desirable.

In Fig. 121, I show how a pin such as shown in Fig. 1 can be used to hold a tag T.

In Fig. 13, I show how such a pin, but preferably with a more rounded bow 60, can be attached to a garment such as 6| such as a ladys dress or the lapel of a mans coat to hold in place a flower K or corsage bouquet.

An open bow such as 60 to some extent replaces a coil so that a single bend 62 between a fixed member 63 and a piercing member 64 makes a sufiiciently springy pin for many purposes.

As in every case my bow or bows extend beyond and under the piercing member, the tendency is to make the pin lie flat. against the cloth, to resist any pressure which might open the pin and also to resist any bending pressure which might bend both members together.

It is, therefore, very difficult to permanently bend my pin and it always, tends to resume its original form and, of course, when it is once closed, especially where the bow and the recess near the point and the V slot are combined, particularly if the top of the shield is closed, it is almost impossible for anything to get at it so that the piercing member is released unintentionally. r

The advantages of. my safety pin, are that it will lie fiat against the sheet material to which it is applied; that it cannot readily be accidentally released by pressure on the piercing member and that the piercing member is locked in place so that it cannot readily pull out.

I claim:

l. A safety pin having a shield or guard enclosing and attached to the outer end ofthe fixed member of the pin, saidguard being closedjon the top and open on the bottom and being formed on the inside with a V-shaped opening, the fixed member being bent in the direction of and in the same plane with the guard to form a bow, the other end of the fixed member being formed as a. spring coil and thence extending as a resilient piercing member under the bow and ending in a point which passes inside the guard and has a recess which engages the v opening, the bow overlapping the piercing member.

2. A safety pin having a fixed member at one end of which is a shield closed at the top and open at the bottom and with a V opening on the inside, the fixed member being bent in a bow in line with the plane of the shield, the other end of the fixed member being bent around and down forming a spring coil and thence extending as a resilient piercing member under the bow and into the shield, there being a recess near its point which engages the V opening, the bow overlapping the piercing member.

3. A safety pin having a fixed member at one end of which is a shield, the fixed member being bent in a bow in line with the plane of the shield, the other end of the fixed member being bent around and down forming a spring coil and thence extending as a piercing member under the bow and into the shield, the bow overlapping the piercing member.
