14 Claims.

to fastening devices of this kind, wherein thecomplete device is made from a single stringer tape folded centrally to bring double acting tinuous rowof links thereon, which collectively will form acomplete fastener when folded censcoops', on the end portions of the tape, defined by the fold, into engaging relationship with each other and forming, at the fold of the tape, an end stop limiting movement of the slider in one direction on the fastening device. features of the invention will be best understood from the following description when taken to-- gether with the accompanying drawing in which certain embodiments of the invention are disclosed and in which the separate parts are designated by suitable reference characters in each of the views; and in which:

Fig. i is a plan view showing one form of fastener made according Fig. 6 is a view similar to Fig. .5 showing another form of tape constaiction.

Fig. 7 is an enlarged d all view of a sectional part of a coupled fastener illustrating one form of reversible or double acting scoop which I employ, part "of the construction being broken away andin section; "and Fig. 8 is a perspective view GO D I In the construction of what is commonly referred to as separable fasteners, it has been the practice to construct the fastener from independent stringers. Quite often, these stringers are coupled together at one end by an end stop coupling which limits opening movement of the These uses of fasteners are by far more common than the completely separable uses as employed on jackets and in connection of one of the stringer .with other articles where complete separation of the parts is desirable. Constructing fasteners of the type and kind pling, it has been necesary to keep track of the different stringer lengths as produced by machines to reassemble stringers of a common length.

With my improved construction, a single stringer will be produced having either a con-' The novel requiring the end stop couends of the link sections may .170 rliy inventionwith part of the construction broken away.

'I have indicated at view ofthe central portion of trally, or the stringer will have arranged thereon, in predetermined spaced relationship to each other, pairs of link sections, so that in severing the stringer tape beyond the limits of said pair of sections, the tape is folded at the space between the link sections in uniting said section to form the fastener. Further, the folding of the tape automatically forms an end stop limiting the movement of the slider in one direction on the fastener and in some instances, the other be coupled together to form another end stop. With all forms of construction employed, the stringer tape or the adjacent sections thereof will have links or scoops of the double. acting or reversible type to provide interlocking engagement between the links when the stringer tape is folded as stated.

In the accompanying drawing, a few adaptations of the invention are disclosed, and in Fig. 1 ill a fastener formed from a single stringer ll having links or scoops l2 attached to one beaded edge l3 thereof. In producing the fastener ill, the links l2 are arranged on the tape ll in a continuous length, as diagrammatically illustrated in Fig. 6 of the drawing, and the tape is folded or curved centrally, as indicated at H in forming a closed loop end on the resulting fastener. The free ends of the tape T II have adjacent end links stops 15 which limit end of the fastener.

movement of a slider It in the direction of said forming a stop limiting the'movement of the slider in the other direction.

In Fig. 2 of the drawing is shown at I! one end portion of another form of fastener made from a I general type and Fig. 5 of the drawing, that is in two sections on the tape with a predetermined spacing, as at 20, centrally of the tape l8, this spacing controlling the folding of the tape in the manner illustrated at 2| in Fig. 2 of the drawing. The centralpart of the tape section 20 crosses the tape ends or what might be termed the link sections of the tapes, as indicated in dotted lines at 22 to form a bridging member 22. The-length of the spacing in will be such as to leave ashort extension of adjacent beaded edges 23 of the'tape, beyond the'iinks, to receive a coupling plate 24, which unites these edges with the crossed central portion 22 of the tape, thus forming. a secure and well reinforced end stop, which limits the movement of the slider 25 in one directhe folded or looped end H tures is desirable. Y

In all of the fastener devices;- illustrated, \the -links or scoops employed-on the-single stringer tion on the fastener H. The other sndof the fastener may be constructed in accordance with the teachings in Fig; 1 of the drawing.

In Fig. 3 of the drawing, I have indicated at 28 another form of fastener made from a single stringer 2'! which has a shorter spacing It between the adjacent links 20 at the central portion of the stringer tape. With this construction, g

the other free ends of the tape 21 are Joined by an end stop coupling 30 and the slider 3| arranged on the stringer sections of the fastener 2! with the wide end portion 32 of the slider extenda ing in the direction of the end stop produced by the central fold of the tape, differing in this respect from the structure'shown in Figs. 1 and 2 where the narrow end of the 'slider extends in this direction.

Another form of fastener similar to that of Fig. 3 is shown at 33 in Fig. 40f the. drawing, the main difference-between the two structures being that a wider spacing is provided centrally of the tape 34 as indicated at 38, in other words, a spacing somewhat similar to that of Fig. 2 but instead of providing an end stop coupling 24; the folded end 36 will be stitched, as indicated at 31 in the operation of attaching the fastener to a support, the wider spacing beyond the end links producing free movement of the needle be- I yond the end links II in this stitching operation. I

simply uniting the end of the fastener where the single tape. is folded, I also provide a reinforced end stop, the reinforcement ,constituting an 'integral part of the tape disposed in a position transversely with respect to the link sections.

This type of-construction has many practical uses, one pf which iszinstallations in trousers where the reinforcement of bottom stop structapes are ofwhat I term the double'acting or reversible type and in Figs. '7 and 8 of the drawing I haveshown, in detail, one form of link or scoop censtructionwhich issuitable for this purpose.

In Fig. '7- of the drawing, represents part of the side sections of a single tape on the beaded edge 42 of which is secured links or scoops 4!. Each link or scoop comprises a yoke shaped end portion 44 which engages the beaded ed'ge 42 and extending beyond the beaded edge upper and lower edges of the-scoop have V-shaped recesses 48 of the opposed links will enter the recess 0 channel 48 of the intermediate link.

With a link construction of this type and kind it will readily appear that the single tapes ma be employed in producing the complete fastene as above described by simply folding the tap I either centrally of a continuous row of links, or a a predetermined space formed between pairs 0 link sections on said tape. It will, of course, b apparent that the length of the link or scoop sec tions will govern the length of the resulting fas tener. However, each tape length will constitut the complete linkage or stringers of the resultinz fastener tobe produced, thus dispensing with th necessity of caring for two independent tapes 0 stringers, as has been the customa y practice.

For purposes of description, the opposed serie of links or scoops on the single tape will be termei stringer chains in defining the portions of thl fastener which are coupled and uncoupled by op eration of the slider, or these portions may bl termed chain parts.

In the different forms of construction shown, i will appear that the central folded portionoi th1 tape isarranged upon and extends transverseh across adjacent ends of .the resulting chain: formed by folding the tape. This integral transverse tape rnember not only forms a reinforcement but alsoproducesa pocket, such as thosq shown at P, P andP", into which the end of thi slider may pass. It also forms a bridge membe1 which checks the movement'of the slider, such a: those shown at 222-28 and 36'.-
