10 Claims.

'This invention 'relates to separable fasteners employing stringers adapted to becoupled and uncoupled by a slider movable along the stringers. More particularly, the invention relates to .a detachable end stop coupling for one end portion of the stringers, by means of which the stringers may be coupled and uncoupled when the slider is arranged adjacent said end stop and further, whereby the end stop coupling may be forcibly separated to detach and uncouple the stringers at said end portion for the purpose of freeing or opening predetermined portions of a garment such, for example, as the upper or lower part of a shirt, sweater, jacket, ,windbreaken or like garment. The novel features ofthe invention will be best understood from the following description when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed, and in which .theseparate parts are designated by suitable reference characters in each of the views; and in which:

Fig 1 is a plan view of one end portion of a fastener made according to the invention showing the stringers coupled together with one of our improved end stop couplings.

Fig. 2 is a view similar to Fig. Y1 showing the parts in detached relationship preparatory to coupling engagement.

Fig. 3 is a section on the line 3 3 of Fig. 1. r

Fig. 4 is a perspective view of the .end portion of one Stringer; and

Fig. 5 is a diagrammatic view illustrating the forcible separation of the coupled end of the stringers with the links of the other endA portion of the Stringer in engagement with each other.

In fasteners of .the kind under consideration applied to sweaters, jackets and similar garments where complete separation of the fastener stringers or chains is desirable, couplings have been provided at one end. of the stringers or chains for similar garment when the wearer is in seated pcsition, or to give access to pocketsin under garments. such as vests, trousers and the like,with out completely opening4 the jacket, sweater or other garment; In other uses, it will provide sep--l arationv of the upper neck portions of the garment. To render such fastener devices practical,

links or scoops of the double acting or reversible `or scoops I6. As the links or scoops applied to `both stringers are of identical construction, the

complete separation thereof, the couplings also serving as an end stop limiting movement of the slider in one direction on the stringers. In devices of this kind as applied to jackets and similar garments, it has been impossible to separate the stringers at the end portion having the detach'-, able couplings without completely separating the fastener. 4

It is the purpose of our invention to provide a detachable coupling and end stop for stringers which can be forcibly detached so as to separate and spread the coupled stringers at said end porof the stringer I I is what is commonly termed the tion thereof, while leaving the otherend portion of the stringers in coupled relationship.- This provides opening of the lower portion of a jacket or the Stringer.

23 longitudinally with respect to the' box brief description of one will apply to all. Each link or scoop comprises a yoke shaped mounting end I1 arranged upon the beaded edges I4, I5 and a substantially diamond-shaped coupling end I8 which forms upwardly and downwardly directed triangular couplings I9 adapted to engage V- shaped recesses 20 inthe links of opposed string ers. Each recess 20 has centrally thereof a coupling element 2| adapted to enter a channel 22 in the outer surface of the links of an opposed Stringer, note Fig. 4. 4

By employing links of the type disclosed, it will be 'apparent that the stringers may be coupled and uncoupled in a universal manner and by sliders moving in either direction on the stringers regardless vof the arrangement of the sliders o n.

Secured to the bead I4 of the strlnger III,y adjacent, ,but spaced from one end link I6, is a pin part 23 of a detachable coupling. The width of .this pin part across the tape is slightly less than the corresponding width of the the'v recess 20 of the end'link of the Stringer I I, the

nose being forked to receive the coupling 2|. in-

said recess. l

Arranged longitudinally of the beaded edge, I-B

box part 26 of the coupling. This part, inthe construction shown, comprises an elongated pin portion 21 substantially similar-to theppin part '20, .excepting that the rib 24 is-not included'and the outer end of the pin 21 has an inturned stop flange 28 which checks movement of the pin part Dart 26. Arranged on opposed sides ofthe pin portion 21, adjacent the flange 2l, are 'similar spring plates 29, outer edges of which are curved inwardly and then outwardly to form elongated clip flanges Sli. The flanges Il are adapted to engage the edges 3i of the pin part 23, as is clearly illustrated in Fig. 3 of the drawing.y However, by exerting a pull on the stringer Il, the pin part 23 may be forcibly withdrawn from the box pari, 2B to separate the corresponding end portions of the stringers I and I i in the manner illustrated in Fig. 5 of the drawing, while leaving the links i6 coupled at the other end portions of the stringers.

In the construction shown, the spring clips are formed on the plates 29 which are riveted o1' otherwise secured to the pin portions 21, as indicated at 32, the rivets being preferably formed integrally with the pin portion 21 and will extend through apertures formed in the plates 29 and then being riveted over in the assemblage of the parts.

In the normal use of the fastener stringers, and when the stringers are separated in the manner indicate in Fig. 2 of the drawing, the slider Slis arranged upon the box part 26 with the narrow end portion 34 of the slider abutting the lower edge 35 of the plates 29. The pin part 23 is rst passed laterally through the open side of the slider 33 and then is moved upwardly into the box part 26 between the plates 2! until the end of the pin part strikes the stop flange 28. With the parts thus assembled, the slider may then be' moved along the stringers to couple the links thereof.

of the clips l0 may be engaged by a finger 'of the hand to flex it outwardly to assist in this operation, this latter procedure being desirable with the larger types of separable fasteners. that is to say, where the links are of large sizes, commonly referred to in the trade as No. Tand No. sizes.

With a fastener of the type and kind under consideration, it will be apparent that in addition to providing for the opening of a lower por- Vt'on of a jacket as described, the neck portion of the Jacket may also be partially opened, while,

at the same time, maintaining the jacket in coupled relationship intermediate the stringer ends.'

Fasteners of this type and kind will iind other practical uses in various installations, generally where it is desirable to obtain quick access to both end portions of an article controlled by the fastener. It might be said that the pin and box part l structure of the fastener operates in the manner of a snap coupling where the parts may be forcibly detached against the action of a spring retaining means and recoupled by snapping the pin partinto'the socket orboxpart. Y It will also be understoodthat instead of arranging the detachable coupling at .the lower portion of a garment, as for example in jackets in the manner heretofore described, that the detachable coupling may be disposed at the top neck portion of the garment and forcibly separated to control a neck opening. In such installations. the slider may be moved along the lower ends of It will be understood that the `flanged side walls 36 of the slider are so spaced apart as to clear the pin 23 and the stringers in controlling the separation or spreading of the lower portion of the garment.
