i To all whom it ma concern;

Be it known t at I, GmnoN SUNnBAcx, a subject of the King of Sweden, residing at Meadville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Separable Fasteners, of which the following is a full, clear, and exact specification.

lhis invention relates to separable fastype of fastener for garments and other urposes, where two iiexible stringersA are ocked andunlocked by a sliding cam-de` vice mounted on both members, the locking being effected by movement in one direction and unlocking by an opposite movement. f

The objects of the present invention are to decrease the weight and bulk, to increase the flexibility and security of locking, and

to provide one foi-m of locking member for both stringers, so constructed and arranged that when properly positioned relatively to each other on the stringers they lock and unlock upon proper movement of the cam sliding device. A further object of the invention is to simplify the cam sliding device, which is possible owing to the reduction of locking members to one form for both stringers, insteadof the different forms heretofore employed on the respective stringers. i

According to the present invention, the stringers are alike, as in some prior types of this fastener, preferably consisting v as herein shown of a fabric tape provided with a beaded or corded edge, upon which the locking members are clamped. The locking members are all alike, and therefore interchangeable, and in general form consist .of contractible jaw portions which are clamped upon the tape and projecting locking portions of elongated cup shape, so that the outside of one member nests within'the recess Yof an adjoining member when in locked relation. Consequently, it' will be seen that the members on one'stringer al-. ternate'with those on the other, so that when the sliding operating device is 'moved back and forth, the lookin members will be engaged and disengag accordin -to the di rection of movement. A furt er feature of the invention resides in the shape and configuration of the locking members, these beingas shown in enlarged Vscale .on the drawings, provided with exterior and interior rounded surfaces, and are somewhat elongated transversely. Thereby. a snug fit is obtained and at the same time ample provision is iven for movement of one on the other wit out coming out when the fastener is fiexed transversely. At the same time this construction gives facility for relative longitudinal movement without disengagement.l teneis, and has particular reference to that In the accompanying drawings: K Figure 1 1s a perspective view on an enlarged scale of a fastener embodying the ncr of locking and unlocking;

Fig. 3 is a cross of Fig. 1; 4 Fig..4 is ing` members showing the recess;

Fig. 5 is a cross section thereof on the line 5 5 of Fig.- 4;

section on the line 3 3 Fig. 6 is a detail view of one of the stringers. `Fi 7 is a cross section thereof on the line 7 of Fig. 6;

Fig. 8 is a cross section of the slider, and

Fig. 9 is an enlarged detail of the locking members. A

1 1 represent stringers which preferably will be made ofv Woven tape having sewed a detail -view .of one of the lockthereto on opposite sides cords 2 2 to form a beaded edge. 3 represents the line of stitching as employed in the preferred construction. Each of these stringers may be secured together at one end by fastening links 4, and will have at the opposite'end .a stop vmember 5. These stop members 5 pass into the slider and limit the locking movement of the slider when they strike each other, becauseit will be seen from the drawings that the total heights of the stop members 5 when they are in contact with each other is greater than the totalwidth of the channel. at the bottom of the slider. 6 represents the sliding cam operating device, which consists of two stamped.- sides 7 each havin a Y-shaped channel forming a tongue, wit theinsides separated to permit passage'of the tape portion'of the stringers 1. 8 represents a cap having a point to litbetween the diverging channels, and 'secured to the slider by a rivet 14. 15 is a ring in which may be placed an o rating tape or bow 1 6.. The stampings may be integral and doubled over or they may be separate, in either event a rigid structure being provided when the cap 8 is applied thereto and the rivet 14 set. l

Fig. 4 represents one of the locking members, which consists of jaws 17-17 having a base portion 9 which isstamped or otherwise formed to provide an external locking projection l0 and an internal recess 11. These members, as well as the locking members 4 and the stamp members 5 are stamped out of flat metal, and the jaws 17, 17 of the locking members are spread apart as shown in dotted lines in Fig. 4 so as to pass over the corded `edges 2 of the stringers. Then the jaws are set by a die press orlother suitable means, the jaws thereby becoming firmly clamped to the -stringers y the compression of the corded edges 2. This will be seen in Fig. 3, where the corded edges have been distorted by the setting of the locking members thereon so as to completely fill theslot in the locking members, and the jaws 17, 17 engaging firmly on the tape immediately behind the corded edges.

From the assembly in Fig. 1, it will be seen that the members 17 on. one Stringer alternate with those on the other Stringer,

and consequently it is possible to make the members on both stringers alike and cause them to lock and unlock readily, and remain'. 'locked even while the fastener is almost doubledon itself.

At the same time, owing to the rounded and transversely elongated shape of the projections and recesses, the fastener is very flexible without being loose. Flexibility is also increased by reason of the relatively large number of locking members provided, which is possible because these members are thin and their projections and recesses can be proportioned so that one will not touch another when the fastener is bent transversely. This is an important consideration in fasteners'of this type. Thus it will be seen that the, shape of the projections and recesses is y`such that when engaged, the stringers have practically nojmovement of separation, but yet the engagement is secure without lbeing stiff, because the locking members on one Stringer can rock or oscillate freely relatively to those on the other Stringer without disengagement.

By the present invention, an improved fastener has been produced which is much more simple and cheap to manufacture than othersheretofore invented, because both stringers as well as the respective members thereon, are alike, and the members themselves can all be made by simple die operations from flat material. The only assembling operations are those required to attach the members to the tapes. The finishing of the locking members such as smoothing or tumbling is very simple, because all are alike and the dies can be so designed as not toi,

require much subsequent finishing of these members. It will be understood that the connecting members/i and the stop members 5 may have jaws 17 on each end similar to Stringer construction, are separately claimed in my application continuous herewith Serial No. 19,474 filed April 6, 1915.

Having thus described my invention, what I declare as new and desire to secure by Letters Patent of the United States is 1. A fastener comprising a pair of iiexible stringers, interlocking members secured at one end thereto in staggered relation, each member having atV the free end a rounded recess on one side and a corresponding projection on the opposite side, the recessed side and the end surface of the projection of each member meeting in an edge and constituting guiding ineans enabling said members to ride one on the other 3. A fastener comprising a pair of ieXi-ii ble stringers, interlocking members secured thereto in staggered relation, each member having a recess on one side and a projection of similar shape on the other, said projections having inclined ends continuous with the recessed side of the member to engage and guide the coperating member over and into engagement therewith.
