FRANKLIN S. MCKENNEY, OF DETROIT, MICHIGAN; ALLEN S. MCKENNEY ADMINIS- TRATOR OF SAID FRANKLIN S. MCKENNEY, DECEASED.

SAFETY-PIN.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed July 12, 1916, Serial No. 108,799. Renewed July 25, 1917. Serial No. 182,803.

T 0 all whom it may concern:

Be it known that I, FRANKLIN S. Mc- KEXNEY, a citizen of the United States of America, residing'at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful improvements in Safety-Pins, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to safety pins, and comprises the construction in which both the pointed prong and the frame or holder may be formed from a continuous piece of wire. A further feature of the invention is that the pointed prong or pin proper is arranged centrally with respect to the frame and lies in substantially the same plane, so as to produce a construction which will lie close against the garment on which it is used.

In the drawings:

Figure 1 is a plan View of the pin;

Fig. 2 is a side elevation thereof;

Figs. 3 and i are opposite end elevations;

Fig. 5 is a cross section;

Fig. 6 is a longitudinal section;

Fig. 7 is a plan similar to Fig. l of a slightly modified construction;

Fig. 8 is a plan showing the pin in use;

Fig. 9 is a cross section similar to Fig. 6 showing a modified constructionof catch for the pin; and

Fig. 10 is a top plan view of the construction shown in F ig. 9.

As has been stated, the pin is preferably formed from a continuous piece of wire, which is fashioned to form a looped frame A with a twisted small loop 13 at one end thereof forming a catch for the pointed prong. This prong C is formed of an extension of the wire forming the loop A, which passes through an eye D on the opposite end of the wire and then passes centrally between the side bars A and A of the loop frame A. The length of the pointed prong is slightly less than the length of the frame loop A, so that it can be moved through said frame and in normal position will stand outward at an angle. as indicated in dotted lines at C Fig. 2. This will permit of insertion through the fabric, and by then pressing the prong upward at one side of the small loop 13 and engaging it with said loop it will be held from displacement.

To increase the security of the catch, the

small loop B in the construction shown in Figs. 1 to 6 is bent transversely into a curved form, thereby leaving parallel guard wires B and B upon opposite sides of the central point of bearing B for the prong C. In the modified construction shown in Fig. 9, the small loop B is bent into the form of a hook, with which the prong C may be laterally engaged. In the modified construction shown in Figs. 7 and 8 the construction is essentially the same, the shape of the outer frame being slightly modified.

With all of the constructions the sharpened prong is arranged centrally between the frame bars, so as to give a symmetrical appearance and to produce a balanced pressure on the fabric, preventing twisting.

What I claim as my invention is l. A safety pin formed of a continuous piece of wire forming an elongated loop having a prong extending centrally of said loop and formed at one extremity of said loop with a keeper to be engaged by the free end of said prong, the other extremity of the loop having a portion engaging the other extremity of the prong, the keeper being shaped to provide a portion adjacent to and alined with the prong when the latter is engaged with this keeper.

2. A safety pin formed of a continuous piece of wire comprising an. elongated loop having a prong extending centrally of said loop from one end of the latter, a relatively small loop being formed at the other end of the large loop within the latter, the wire being crossed at the juncture of the large and small loops to form a guard for the prong point, the free end of the small loop constituting a seat for the prong, the small loop being bent between its free end and tincture with the large loop to allow alinement of the prong with said juncture.

3. A safety pin formed of a continuous piece of wire comprising an elongated loop and a prong extending substantially centrally thereof, the end portions of the loop being correspondingly bent, a small loop being formed at one extremity of the elongated loop and at one side of the plane of the elongated loop, one end of the prong being engaged in said small loop, the other end of the prong being provided with a keeper at the other end of the elongated loop, said keeper comprising a small loop projecting into the large loop and bent intermediately to form a seat for the prong the free end of said prong being formed at and a guard for the point thereof. one of the bent loop extremities, and the 4. A safety pin, comprising a body porother end of the prong being engaged with 1G tion forming an elongated loop having its the other bent extremity.

5 extremities correspondingly bent, and a In testimony whereof I afliX my signature;

prong extending longitudinally of said loop at one side of the plane thereof, a keeper for FRANKLIN S. MCKENNEY;
