11 claims. (ci. 24.205)
l This invention relates to separable fasteners wherein each end of the stringers is equipped with means whereby the stringers may be separated or pulled apart at either end when the slider is adjacent thereto. Further, the invention comprises a pull apart end vstop construction which will maintain the stringers normally in coupled relationship. The novel features of the invention will be best understood from the following descriptions'when taken together with the accompanying drawings, 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. 1 is a face view showing both end portions of a fastener, made according to my invention with parts of the construction broken away and in section. y

In separable fasteners ofthe type and kind employing stringers with a slider movable along until it engages thebox part at the other end thereof, at which time the pin part was removable. Where long stringers are employed and furthermore where quick Separation of the fasteners is desirable, the foregoing method of procedure would be objectionable.
To overcome the objections to fasteners of the kind defined, I have provided at the stop end thereof, opposite thevbox and pin end, means providing detachment or separation of the stringers, with the slider arranged at said end, whereby the stringers may be literally pulled apart, thereby accomplishing the desired Sep- 'arationas quickly as this pull apart operation can possibly be performed .by the individual operating the fastener.
This pull apart separator construction comprises a bar or rod like member preferably arranged on the Stringer to which the pin part iS attached, and having means in the form of a reduced portion facilitating free travel of the Slider thereover. The ends of the bar portion have ,enlarged members normally engaging the slider to prevent vaccidental Separation of said end of the stringers, particularly when both tapes of the stringers are strained in the direction to separate said stringers.' The pull apart separa.-
tion iS accomplished by pulling the Stringer lto which the separator bar`is attached laterally,
i while at the same time, moving the slider invthe direction of said end of the stringers. This pull apart structure also includes the use of a defined Stop on the other Stringer for maintaining the as the Stringer' II will be the pin part or pull away Stringer. Stringer I0 has a bead I0' and Stringer II has a bead Il.
One end of the Stringer has a detachable coupling of more or less conventional box and pin construction. The box part. being indicated at I2 and attached to the Stringer I0, and the pin part I3 attached to the Stringer II. As in other devices of this vkind the pin part is nsertable and removable .from the box part when the slider I4 is arranged adjacent the box part or the shoulder I5 thereon.
At the other end of the Stringer I'IJ is a stop I6 in the form of a ball member, suillciently large in diameter to check movement and detachment of the slider. I4 when moved in the direction of Said end of the stringers. To the corresponding end of the Stringer II is Secured one of my improved'separators Il, in the form of a flattened bar I8, having a thickness less than the Spacing between the conventional inturned flanges I9 at oppositesides of the slider Il. As is known, the spacing between'these flanges is to clear and ride freely over the tapes of the stringers as the slider is' moved longitudinally thereof.
The separator I`|y includes at its inner end a. link-like projection 20 spaced from the end link The bar I8 is recessed on its inner end, as seen at 23', adiacent the link portion 28 to receive the link 23 on the Stringer I8 next adjacent the link 22. At the outer end of the bar I8 is another enlargement 28, which is normally disposed beyond the end 21 of the flanges I8 (See Fig. 1), so as to facilitate lateral withdrawal of the tape II through-the side of the slider I4. The ends 28, 28 of the separator I1 are substantially of the same thickness as the thickness of the links of the stringers, so as to freely enter the channels of the slider body, through which the links normally'pass. The enlargement 28 also has on opposite sides projecting knobs 26' to check movement of the slider on the Stringer II.
When the slider I4 is in its normal closed position, the Stop I6 is positioned beyond the wide end 28 of the slider body, having the diverging channels 29 and 38 separated by the connecting web 3I.
In pulling the stringers I and Il apart, the Stringer II, or the article to which the same is attached, is grasped in one hand and pulled laterally while the slider I4 is moved in the direction of the stop I8 by the other hand. At the beginning of this operation, the parts will assume a position substantially similar to that illustrated in Fig. 2, in which figure, it will be noted that part of the bar I8 has been moved through the side of the slider, and the enlargement 26 is out of engagement with the slider body, whereas the link end 20 is positioned at the narrow or contracted end`32 of the slider.
In this position of the parts the slider I4 is free to move along the Stringer I8 to the point of engagement with the Stop I6. The result of this operation is indicated in Fig. 3, in which position the Stringer I I is shown completely removed from the slider I4, and this represents the beginning of the pull apart Separation of the stringers I8 and I I. On completing this operation the pin I3 is withdrawn from thebox part I2.
In re-assembling the parts, the slider I4 is brought into engagement with the box p'art I2,
lar to that of Fig. 2, whereas Fig. 6 shows the complete separation of the two stringers, the same as in Fig. 3.
It will be understood at this time that the recess 23 serves the Same function and purpose as the removal of the coupling end of the link 38 in providing the necessary clearance for free detachment of the separator I1 from the slider I4.
The structure shown in Fig. 'I represents a slight modification of the separators I1 and 33. In this figure the separator is generally identied by the reference numeral 31, and this separator includes a bar portion 38 which takes the place of the rod of the separator 33 and the bar I8 of the separator I1. The bar 38 has enlargements-38 and 48 at the ends thereof which take the place ofthe enlargements 20, 26 and links 35. The bar 38 is not recessed similar to the recess 23' in the bar I8 so that it would be used in a link Structure similar to that shown in Figs. 4 to 6 inclusive.
With the Structure shown in Figs. 1 to 3 inclusive and Fig. 'I the separator unit may be produced in a form of a casting and may be die cast directly upon the Stringer tape. In some instances, however, this device may be made of stampings and attached to the Stringer Itape in the manner of tape and similar formed links or scoops. On the other hand lt may be pre-cast and then attached to the Stringer tape.
The separator member or device may be said to comprise an extended tandem linkage. This linkage by reason of the spacing of the link porthe pin part inserted in the box part through the channel 30 of the slider, after which the slider iS moved in the direction of the Stop I8 in re-coupling the links of the stringers I0 and I I.
In Figs. 4 to 6 inclusive a slight modification of the structure shown in Figs. l to 3 is illustrated. With this conStruction'I have substituted for the separator I1, a Separator 33 in the form of a rod 33 having reduced ends riveted or otherwise coupled, as, seen at 34, to spaced links 35, which links may be substantially of the same form and construction as the links of the stringers employed.
The diameter of the rod 33' will be Such as to pass freely between the spaced inturned flanges of the slider as with the bar I8, and as the structure and mode of operation of the device as seen in Figs. 4 to 6 inclusive is substantially the Same as that in Figs. 1 to 3 inclusive, further detailed description with regard to the several parts is not necessary.
It will be noted, however, that one of the links 38 of the Stringer opposite to that which has the separator 33 thereon has its inner coupling end removable to provide clearance for the swinging of the separator within the slider, as will appear tions thereof with respect to the length of the flanges of the slider will normally retain the stringers against separation. but has a thin wall shank or bar portion joining the link ends which is free to pass through the slot or space formed between the inturned side flanges of the slider when the Stringer and slider are. relatively moved, as heretofore Set forth.
