SAFETY ."PIN.

Application filed September 30, 1522. Serial No. 591,609.

To all whom it may concern Be it known that'I, VVARR N C. Horr- MASTER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a new and useful Safety Pin, of which the following is a specification.

This invention relates to safety pins, and has for its object the provision of a safety pin formed from a single piece of wire which is bent to define the pin proper, the head, the coil, the guard or keeper and also a guide which extends diagonally across the head, and which operates not only to direct the point of the pin to the keeper, but also exerts a bracing or stiffening action which will increase the rigidity of the head and lessen the likelihood of its bending under strain.

With these objects in view, the invention consists in the details of construction and ar rangement to be hereinafter more fully described and claimed and illustrated in the accompanying drawing, in which- Fig. 1 is a perspective view of the pin;

Fig. 2 is a cross section on the line 22 of Fig. 1;

Fig. 3 is a top plan view with the pin in closed position.

Referring more particularly to the drawing, 1 have shown the pin as formed from a single length of wire 10, of a resilient nature, having a spring coil intermediate its ends, as shown-at 11, and defining the relatively stationary body portion 12, and the movable pin proper 13, which has its free end preferably otl'set, as indicated at 1d, and formed with a point 15. The body portion 12 is bent at one end to define C-shaped loops 16 which are substantially parallel, and which are connected by transverse U-shaped loops 17, which constitute the keeper proper, within which the pointed end of the pin is engaged. The loops l6 and 17 form the head of the pin.

The novelty of the invention lies in the construction of the free end of the wire which is coiled about the body portion 12 at 18, and flattened at 19, and said flattened portion is extended diagonally across the head formed by the loops 16, with the extreinity disposed between said loops, as clearly indicated in Fig. 2.

In the use of the pin, it will be seen that the point 15 is forced through the fab-- ric to be held and is then engaged between the loops 17, the inherent resilience of the spring wire maintaining the closed position. The point 15 will be disposed between the loops 16, which are almost in contact, so as to afford a protection which will prevent likelihood of scratching the user.

In the operation of inserting and fastening the device, it is to be noted that the free end of the pin point will be guided by the flattened diagonal end 19, and be directed thereby to the keeper 17 regardless as to which side the pin may be operated, enabling the pin to be pinned or unpinned from either side. The diagonally extending guide 19 not only performs this function, but also operates to brace or stiffen the head formed by the loops 16, so

that distortion under strain will not likely occur. t is also out of the way of the clothes being pinned.

I claim A safety pin formed from a single'length of wire having an intermediate spring coil, a body portlon, a movable pm having a pointed end, and a head forn ied with substantially parallel loops forming a guardconnected by transverse loops constituting a keeper, the free end of the wire being coiled about the body portion, then flattened and extended diagonally across the head beyond the keeper, w th the extremity fitted between said parallel loops, said flattened diagonal. portion constituting a guide engageable by the point of the pin to direct the latter into said keeper.

In testimony, that I claim the foregoing as my own, Ihave hereto atlixed my signa ture. l
