SAFETY PIN.

Specification of Letters l atent.

Patented Mar. '7, 1922.

Application filed June 10, 1921. Serial No. 476,454.

To all whom it may concern:

Be it known that I, GHARLns lrl. SHER- woon, a citizen of the United States, and resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Safety Pins, of which the following is a specification.

This invention relates to improvements, in safety pins, and has for its object to provide a simple, inexpensive, and efficient locking device forpreventing accidental disengagement of the pin tongue from the keeper member of the pin. To the foregoing and other ends, which will hereinafter appear, the invention consists in the features of construction, and the arrangements and combinations of parts, set forth in the following description and particularly pointed out in the appended claims.

In the drawing:

Figure 1 is a side elevation of a safety pin provided with a locking device embodying the invention;

Fig. 2 a side elevation showing the opposite side of the pin from that illustrated in Fig. 1; and

Fig. 3 a sectional view taken on the line 3-3 of Fig. 1. v

' The safety pin proper may be of any suit able or known construction. As illustrated, it comprises a piece of resilient wire bent to form a keeper-carrying member 10 and a pin-tongue member 11 connected together at one end by an'integral coil portion 12 which forms the usual spring-hinge connection between said members. One arm of the usual U-shaped keeper 13 is rigidly hold to the free end of member 10 and the other arm 14 thereof is provided as usual with an inwardly facing channel adapted to receive the free pointed end of the tongue member 11 in the well known manner, as indicated in 1 and 2. The parts heretofore described are of well. known construction.

In order to prevent accidental disengagementof the tongue member 11 from the keeper I provide a locking member or safety device which is adapted to prevent. flexing, bending, or swingingof the, tongue member either toward or from the keeper-carrying member 10, and thus prevent the pointed end of the tongue member from being pressed inwardly below the side walls of the channeled arm 14 of the keeper or from being pulled from the channel in said arm 14lby outward flexing or bending of the tongue memberunder a severe pulling strain.

The improved safety device or latch is formed in its entirety of a single narrow strip of sheet metal doubled upon itself to form two opposed and slightly diverging

arms

15 and 16 connected together at their converging ends by an integral tubular pivot portion or sleeve 17. The keeper-carrying member 10 of the safety pin extends through the tubular portion or sleeve 17 of the locking device, said sleeve having a snug rotating and sliding engagement with member 10 to permit the locking device to be swung about member 10 and shifted longitudinally of said member.

The free end of the arm 15 is bent or curved upwardly and laterally and then downwardly to form a slightly resilient hook 18 adapted to be engaged over the tongue member 11 to resist outward pulling strains. The downwardly turned end edge of the hook is preferably doubled upon itself to form a stiffening flange 19 for reinforcing said end edge and to provide a rounded nose 20. The end of arm 16 is bent laterally toward arm 15 to form a shelf or abutment 21 below hook 18 adapted to resist pressure of tongue member 11' toward member 10. A narrow tongue or lug 22 is formed on the inner end of shelf 21 intermediate the side edges of said shelf." LugfQQ extends through a slot 23 in arm 15 and is bent against the outer side of said arm to prevent separation of'the divergent ends of the

arms

15 and 16. The shoulders formed by the inner end of shelf 21 at opposite sides of lug 22 abut against the inner side of arm 15 and prevent movemcntof the divergent ends of arms 15 and 1-6 toward each other. Shelf 21 is preferably formed'to provide a rounded edge ornose 25 direct-ly under nose 20 of hook 18 and is bowed downwardly to form a channel curved on the same arc as the surface of the tongue member 11, as shown in Fig. 3. Hook 18 is also preferably curved on the same are as the tongue member 11, and noses 20 and 25are spaced apart a distance less than the diameter of tongue member 11 so as to form a restricted throat or slot 26 through which the tongue member is adapted to pass only after flexing of the resilient hook away from shelf 21.

The operation of the device is as follows: The free end of the loc 'zing device being disengaged from member 11, and member ll. being disengaged from keeper 13 the tongue member is passed through the pieces of fab ric or the like to be pinned together and the tongue member is then engaged. with the keeper in the usual way. The free end of the locking device is then. swung toward the tongue member and pressure is exerted thereon to force the tongue member through the throat 26, the

rounded edges

20 and 25 facilitating this action as the looking device is pressed against the tongue member. \Vhen it is desired to remove the pin, pressure or pull is exerted laterally on the locking device to snap the same oil of the tongue member, whereupon. the safety pin may be removed in the usual way.

It will be obvious that various changes may be made in the construction of the im proved safety lock without departing from the invention. In Fig. 2 the preferred manner of attaching the pin to fabrics is shown, but it will be obvious that it is not essential that this manner of attaching the pin be employed. .111 Fig. 2 the tongue member is shown passed four times through two plies of fabric 27 and 2S and the safety lock is shown engaged with the tongue member of the pin intermediate the second and third points of penetration.

An important feature of the invention consists in the provision of a safetylocking device adapted to be adjusted longitudinally of the pin so as to permit locking the tongue and keeper-carrying members together at any convenient point. A further highly important feature of the invention consists in providing a locking device adapted to separably connect the keeper-carrying member and the tongue member of the pin, said device being so constructed as to resist compression strains as well as pulling strains on the members.

hat I claim is:

1. The combination with a safety pin havbig a member carrying a tongue keepcr and a pin tongue member connected with said keeper-carrying member of an. auxiliary safety device pivotally and slidably held to thehcepeucarrying ucmber and provided at its free end with srniiug clasping means for gripping the tongue member and holding the tongue member against movement both toward. and from the keepe1L'-cari'yiug member, said spring clasping means having a restricted entrance throat at one side there" of to permit engagement and disengagement of the clasping means with the tongue memher while said tongue member is engaged in the keeper solely by pressure on said device transversely a plane intersecting the tongue and keeper-carrying members of the pin.
