Specification of Letters Patent.

Patented May 23, 159168..

. Application filed January 13, 1916. Serial No. 71,876.

Be it known that I, LOUIS BLUMnn'rHAL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York, have invented new and useful Improvements in Snap-Fasteners, of which the following is a specification.

This invention relates to a device for securing the opening of a garment which can readily be attached and cannot accidentally become disengaged when in action.

The invention comprehends a plurality of spring loop members projecting outwardly from a base member, and a yoke bar adapted to coact with the members.

The essential object of the invention is to provide a space betweenthe loop members so that when it is desired to have the yoke bar connect with the loops it can be inserted in the space to spread the loops. 'When the bar ispressed the entire distance into the opening the loops will contract by reason of their inherent resiliency and thus positively lock the yoke bar in place.

The. deviceis designed to provide meansfor preventing the yoke bar from laterally shifting after it is pushed into place between the loops.

The invention is more fully descrlbed 1n the following specification and claims and illustrated in the accompanying drawing in which:

Figure 1 represents a front viewshowmg the device attached to a garment. Fig. 2 is a side view of a yoke bar. Fig. 3 is a front view of a spring loop member showing the yoke bar snapped in place. Fig. 4 is a plan view of the same.

In this drawing is shown a snap keeper preferably constructed of a single length of spring wire having a pair of eyes a formed at adjacent ends of the wire. These eyes serve to 'firmly attach the device by means of stitches b to theflap of a garment c as indicated in Fig. 1. A. pair of logp members (Z are formed by convoluting the wire on each side of an opening 0 at the central portion of the device. The loops are oined together by a contiguous base member 7 which is preferably concaved.

As indicated in Fig. 4 each loop has a plurality of convolutions to form a double outwardly projecting loop one being diametrically opposite and axially ad acent the other. There are thus two pairs of loops one pair (i being joined together by the base 'member f-While the other pair d are united to the eyes a by branch wires 9 extending from the lower portions of the loops.

'The yoke connection includes a bar provided with a concavecl central member 1:.

and having convexe'd side portions 11 w are united to a pair of oppositely located Y eyes 7' by the upward extensions is. The yoke is formed of a single piece of wire and the eyes are for the purpose of attaching the yoke by sewing to the garment as shown at vm in Fig. 1. It will be seen that whenthe yoke member is placed in alinement or register with the space between the outwardly projecting loops and pressed home the central concaved portion will rest on the base member f with the protruding convexed portions i forming stops on each side of the base to prevent lateral playof the yoke. In this connection it should be said that when the yoke bar is pressed into the opening until it reaches the axis of the loops it will compress them, hence widening the opening. Then when the yoke bar is pushed farther into the opening the jaws of the loop will spring together and the bar will snap onto the base member. In this position the yoke bar cannot be disconnected from between the jaws of the loops until they are again snapped apart by the withdrawal of the oke bar. a

While I have shown and claimed this device as being made of wire, it will of course be understood that I do not limit myself to this material and that the device may be made of any suitable material.

I claim:

1. A snap fastener comprising a base member, a plurality of spaced spring loops projecting outwardly from the base, and means for fastening the device to an article; combined with a yoke member adapted for insertion between the loop members.

2. In a snap fastener the combination with a pair of outwardly projecting spring 'loops formed of wire, eyes extendingfrom the lower'portion of the loops and including a base member to join the loops, of a adjacent ends of the wire, of a yoke member adapted for insertion between the loops to coact with the base, and means for preventing lateral movement of the yoke member.

4. In a snap fastener the combination with a pair of outwardly projecting spaced spring loops formed of wire, a base member joining the loops, including eyes located at adjacent ends of the wire, of a yoke member adapted for insertion between the loops and having protuberances for preventing lateral movement and to coact with the base member.

5. In a snap fastener the combination with a pair of outwardly projecting spaced Copies 01 thjl spring loops-formed of wire, a base member joining theloops, and eyes located at adjacent ends of the wire, of a yoke member adapted for insertion between the loops havmg upward extensions with eyes includingv 20 concaved and protuberant portions for preventing lateral movement and to coact with the base member.

In testimony whereof I have hereunto set my hand in the presence of two subscribing 25 commissioner oi Patents,

Washington, D. 0.
