Fatented 1, 1921.

Application filed. April 23, 1919.. Serial No. 292,064.

To all whomit may concern.

Be it known that I, Josfsrrr H. LYNCH, a citizen of the United States, residing in Asburv Park. in the county of Monmouth and State liew Jersey, have invented certain new and useful Improvements in Safety-Pins, of which the following is a full and clear specification. n

The present invention relates to sarety pinsg'and par icularly to safety pins such as are adapted foruse in laundries and such, where the pinswith suitable identification marks thereon are attached to the difierent articles to be laundried before they pass through the laundrying process, so that after they have been laundried, they may readily be identified. It will thus be seen that for this purpose, it is very desirable to have a pin which will not readily become.

unfastened or' opened, and which at the same time is strong and durable enough to withstand the crushing force to which it is often subjected by the machinery usually used in the laundries; The object of the present invention is to provide such a pm, and other and further objects will appear in the specification and be pointed out in the annexed claims.

In the accompanying drawings, whlch illustrate my invention, Figure 1' is a view of what I will call the bottom of the safety pin, showing the sl ds able member in looking position;

Fig. 2 is a similar view showing the able member in open position;

Fig. 3 is a View of the top of the pin, showing the slidable member in looking position;

Fig. 1- is a top perspective view of the pm with the slidable member removed, and

slid- Fig. 5 is a perspective View of the slid-.

able locking member. 7

Referring more specifically to said drawings, 1 indicates a shield formed in any suitable manner from a flexible material such as sheet metal, and having the extended portion 2 upon which may be placed numbers, letters, or any other desired marks. The sides of the shield are'bent over as indicated at 3 and 4;; the bent portion 3 embracing end of the pin member 5. The portion 7 is turned down in orderto brace the bent portion-or keeper i; and for the sake of uniformity the portion 6' is also bent down.

A. slot 8 is provided in the shield l, in which the slidable looking or obstructing member 9 is disposed. extending upper surface 9 of this member 9 is of sufiicient length to extend substanti ally from the inner edge of bent over portion 8 to the inner edge of bent-overportion 4L, and thus when in the position shown in Fig. 3 it locl s the relatively movable end of pin member 5 against displacement from keeper 4%. However, when the slidable memher 9 is moved to the open position shown in Fig. 2, the pin member may readily be removed from keeper 4:.

In order to prevent the accidental displacement of member 9 from open or closed position, the slot 8 is made relatively narrow at its intermediate portion, as shown; and the member 9 is so proportioned that in order for it to pass by the intermediate portion of the slot, it has to be compressed. The resistance thus offered to its passage tends to prevent its acc1dental displacement. When at either end the member expands to normal.

The transversely The height of member 9 preferably is such that when it is in the slot 8 the top surface 9 is substantially in alinement with the top surface of bent-over portions 3and 4; in

Furthermore, this construction has the ad-' vantage that it gives a smooth and uniform upper surface to the pin so that the slidable' member is unlikely to catch on and become unlocked by articles with which it comes in contact.

T he sides of this member 9 are also preferably curved inwardly as at 9 so that any pressure on the top of the pin which is exerted on said member will tend to compress the member vertically without causing itto expand laterally; hence it will remain in its original position with relation to bent over portion 4:, since the latter will also be compressed, and it will therefore not become inoperative. 7

I claim V 1. A. safety pin comprisinga pin member, a shield having one side rigidly secured to one end of said pin member and the other side forming a keeper adapted to receive the other end of said pin member, said shield being provided with a slot, a slidable member disposed in said slot adapted to lock the end of said pin member in said keeper, said slidable member being movable into and out of locking position, and means adapted to offer resistance to the movement of said slidable member into and out of locking position.

2. A safety pin comprising a pin member, a shield having one side rigidly secured to one end of said pin member and the other side forming a keeper adapted to receive the other end oi said pin member, said shield being provided With a slot relatively narrow at its intermediate portion, and a slidable member disposed in said slot adapted to lock the end of said pin member in said keeper, said slidable member being movable into and out of locking position and adapted to be compressed by the walls of said slot during such movements.

3. A safety pin comprisin apin member, a shield of flexible material iaving opposite sides bent over, one bent portion embracing and secured to ene end of said pin member and the other bent portion forming a keeper for the other end of said pin member, and a separate locking member secured to said shield and movable thereon into a position substantially closing a portion of the pin receiving portion of said keeper, said locking member having its upper surface substantially in alinement With the upper surface of the bent-over portions of the shield.

4. A safety pin according to claim 3 in which the sides of the locking member are curved inwardly.

5. A safety pin comprising a pin member, a shield having one side rigidly secured to one end of said pin member and the other side forming a keeper adapted to receive the other end of said pin member, a compressible locking member associated with said shield and adapted to lock the end of said pin member in said keeper, said locking member being movable into and out of loci mg position, and means for compressing said locking member during such movements.
