MARIE S. FEDERMAN, OF NEW YORK, N. "Y.

SNAP-FASTENER.

Specification of Letters Patent.

Patented Feb. 2-7, 1917.

Application filed February 7, 1916. Serial N 0. 76,534.

To all whom it may concern:

Be it known that I, MARIE S. FEDERMAN, a citizen of the United States of America, residing at New York cit county and State of New York, have invented certain new and useful Improvements in Snap-Fasteners, of which the following is a full,'clear, and exact description.

This invention relates to improvements in snap-fasteners for gloves, garments or the like, the object being to provide an inexpensive but effective fastener of this variety. To accomplish this result I employ a socket-member and a button-member arranged to interlock one with the other, special fastening means being provided. to maintain said members in interlocked relationship.

I will now proceed to describe my invention in detail, the essential features of which will be summarized in the appended claim, reference being had to the accompanying drawing, forming part hereof, wherein Figure 1 is a sectional view proved fastener;

Fig. 2 is a sectional plan view enlarged, of the socket-member, the section being taken on a line 22 in Fig. 1; and v Fig. 3 is a top plan view of the socketmember illustrating the locking element before it is pressed into place.

vAs herein illustrated, my invention com prises a socket-member 1 and a cooperating button member 2 arranged to be engaged by the socket-member, as shown in Fig. 1. The button-member 2 consists of a base 3 and a rounded head 4 having a rounded shank 5 of less diameter than the head to form an annular recess. The round-headed shank is adapted to be forced into the pocket 6 of of my imthe socket-member 1 and to be retained therein by a locking element 7.

The locking element 7 is held in slots 8 out into the wall of the pocket 6 and consists of a yieldable oblong shaped ring or loop which is originally circular as shown in Fig. 3, and pressed into the slots 8, the pressing action changing the shape of the ring from circular to oblong, and at the same time pressing the sides 9, 9 of the ring inwardly as at 9* to form ridges. The ring is preferably in one piece in order thatthe ac- Way, but remains tion of forcing the head 4 into the pocket will spring the ring or loop intermediate its ends and not at its ends, which would be the case if the ring was not in one piece or joined at the ends thereof.

at their corners providing stops orapart but will assume their normal position as soon asthe said head has been forced entirely therebetween. The button-member will finally come to rest with the side-members of the ring engaging the reduced portion 5 of the head of the button.

The circular locking element 7 is of thin slightly resilient flexible metal, adapted at all points to be forced in through said slots of the socket by a suitable tool, forming ridges 9 which will engage the material of the pocket at the ends of the slots and hold thelr position within said pocket on each side of the neck of the button member and in the path of insertion and withdrawal of said button head, permitting it to pass through said ridges on insertion so that they will fit in behind it and lock it in place. The deformed locking shape of said ring (shown in Fig. 2) is quite different from its normal shape displayed in Fig. 3. I have no need of a special irregular construction in the first place. A simple circular ring is easily obtained and fulfils the conditions stated if made of material which will yield for the production of the ridges 9 but permit them to hold their position by engagement with the material at the ends of the slots.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

In a snap fastener, a socket member adapted to receive the head of a button member and having. a socket pocket provided with slots, in combination with an endless ring of slight resiliency, any portion of said ring being adapted to be forced inwardly through said slots into the path of movement of a button head entering or leaving said pocket, the inwardly projecting portions being held in position by the slight resiliency of the ring and adapted to yield sufiiciently to the inward pressure of a head,

though tending to obstruct its Withdrawal.
