relationship with each other.

Still more particularly, the invention deals with a box member having means for angularly supporting the slider when brought into abutting engagement therewith to provide proper alinement of the pin part with the box part of the separator to facilitate freeand easy coupling and uncoupling of the pin and box parts.

The novel features of the 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, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is a diagrammatic plan and sectional View of the box and pin structure of a pair of stringers illustrating initial engagement of the pin part with the box part in coupling the stringers.

FIG. 2 is a view, similar to FIG. 1, showing the pin part in a further advanced position in the box part.

FIG. 3 is a view, similar to FIGS. 1 and 2, showing the box and pin parts in elevation and illustrating a still further advanced position of the pin in the box part.

FIG. 4 is a View, similar to FIG. 3, showing the pin and box parts fully coupled and indicating, in part, the slider partially withdrawn from the pin and box parts.

FIG. 5 is a section substantially on the line 5-5 of FIG. 3 on an enlarged scale; and

FIG. 6 is a section substantially on the line 6-6 of FIG. 4 on an enlarged scale.

In the accompanying drawings, I have illustrated, in part, at 10, 10' part of a pair of stringer tapes, to one surface of which are secured coil fastener elements 11, 11 by stitching, as diagrammatically seen at 12, 12'. Looped ends of the coils project beyond the adjacent abutting edges of the tapes 10, 10', as clearly indicated by the abutting tapes at 13, projecting portions of the coils having offset interlocking elements 14, 14', as clearly illustrated in FIGS. 1 to 4, inclusive, no attempt being made to show these portions in the diagrammatic illustration of FIG. 6.

At 15 is shown the slider for coupling and uncoupling the stringers. The slider comprises two

walls

16 and 17, note FIGS. 5 and 6, having'side

flanges

18 and 19 respectively, forming the contour of the channel of the slider body which diverges at the wide end 20 of the slider body, which end has, centrally thereof, the connecting web 21 separating the two channels, as with other structures of this type and kind.

The cross-sectional contour of the slider body. is such as to bring the tapes into a position substantially centrally of the sides of the slider body, Where the tapes pass through the side openings 22. It will also be apparent, from a consideration of FIG. 6, that the inner surface of the wall 16 of the slider is recessed, as seen at 23, to

3,170,207 Patented Feb. 23, 1965 clear the stitchings 12, 12', thereby preventing wear on the stitches in the operation of the slider along' the stringers.

At the separator end of the fastener, the stringer tapes 10, 10' have their ends .folded, as illustrated at 24, 24

g in FIG. 5, and thetapes are reinforced by additional tapes 25, 25', which are stitched to the tapes 10, 10' including the folds 24, 24' therein. This construction 10- cates the tapes 10, 10' in substantially the same relationship as the tapes as they appear in FIG. 6 of the drawing. Cast or otherwise secured on the end portions of the tapes 1t), 141', including the reinforcements 25, 25', are box and

pin parts

26, 27 of the separator.

The side portion of the stop or box part 26 secured to 10-25 includes an inwardly projecting reduced portion 28, having an integrally projecting hook 29, the hook forming a recess 30 on the inner surface thereof. The hook 29 projects from the surface 31 of the pin engaging socket or channel 32 of the box part 26, the channel being partially defined by side flanges of the box part, one of which is seen at 33.

The pin part 27 has a rounded exposed surface 34 terminating at a recessed portion 35 in a rounded corner 36. The pin part 27 extends beyond the edge of the reinforcement 25' and has a projecting interlocking finger or lug 37, which partially forms the recess 35. The lug 37 has a rounded projection on one side surface thereof, as seen at 38, and a recess 39 on the opposed side surface thereof, 38 operating in conjunction with the recess 30 and an end loop on the coil 11, or the element 14 thereof engagesthe recess 39, as seen at 14" in FIG. 4 of the drawing, when the pin and box parts and the stringers are coupled relationship to each other, this figure also clearly illustrating the engagements between 38 and 30 and the arrangement of the hook 29 within the recess 35. The box part 26, at its outer end, is generally of the contour clearly shown in FIGS. 3 and 4 of the drawing and is of greater thickness than the extension 28 thereon. This greater thickened portion has, on its inner surface, angularly disposed walls 40, against which the contracted single channel end of the slider operates, as will be later described.

Considering'FIGS. 1 to 4, inclusive, it will be apparent that, in the operation of coupling the pin part with the box part, preparatory to engaging the stringers, the slider 15 is brought into engagement with one of the angular surfaces 44}, as illustrated in FIG. 1 of' the drawing, at which time the pin part is moved into the position, substantially as seen in said figure and, in continuing this inward movement of the pin part, the slider is swung from the position shown in FIG. 1 to a'position substantially as seen in FIG. 2 and this movement is further continued until the lug 37 or the projection 38 thereon strikes the hook 29, as seen in FIG. 3 of the drawing. This checks coupling engagement of the pin part with the box part, after which the user operates the slider, moving the same from left to right or, in other words, from the position of FIG. 3 to the position of FIG. 4, in which last operation the slider moves the pin part 27 into coupled engagement with the box part or, in other words, with projection 38 on the lug 39 in engagement with the recess 3% on the hook 29 and with the element of the end loop of the coil 11 engaging the recess 30, as illustrated at 14". With the parts in this position, it will be apparent that the stringers are securely coupled against separation adjacent the pin and box parts.

In uncoupling the pin and box parts, it will be apparent that the slider is moved from the position of FIG. 4 into the position shown in FIG. 3, in which position the coils 11, 11 of the stringers are separated by the slider, after which the pin part 27 is withdrawn from the box part or, in other words, moved from the position of FIG. 3 to the position of FIG. 2 and, then, finally out through the slider when the slider is in the position shown in FIG. 1. The above description describes the step fashion of continued operation between FIG. 1 and FIG. 3 and from FIG. 3 back to FIG. 1, it being understood that an independent operation is required to control movement of the slider from FIG. 3 to FIG. 4 and vice versa.

From the foregoing, it will be apparent that the wall 17 of the slider, including its flanges 19, operates on the stringer tapes; whereas, the wall 16 and its flanges 18 operate upon the coils 11, 11'. By minimizing the space between adjacent surfaces of the

flanges

18 and 19, not only is the tape centrally located, but substantial thicknesses of the box and pin parts are made possible for engagement with the tapes, including the reinforcements 25, 25', as will be clearly apparent from a consideration of FIG. 5, the thicknesses illustrated being those of the pin part and the reduced extension 28 of the box part, upon which the contracted end of the slider operates. It will be understood that the reinforcing tapes 25, 25' are stitched or otherwise secured to the

tapes

10, 10, including the folded-over portions 24, 24' and the stitchings are diagrammatically illustrated at 41, 41 in FIG. of the drawing.

Considering FIG. 5 of the drawing, it will be apparent that the rounded corners of the pin part and the reduced extension 28 of the box part operating in conjunction with the rounded surfaces of the

flanges

18 and 19 will provide for free movement of the pin part inwardly and outwardly through the box part and, in FIGS. 1, 2 and 3 of the drawing, clearances between 27 and 28 and the flanges 19 are illustrated by the dotted line showing of the flanges 19 in said figures, it being understood that the illustrations are diagrammatic.

For the purpose of this document, the right end of the pin and box, as seen in FIGS. 1-4, shall be considered the inner or inward end of these elements and the opposite or left end, as viewed in these figures, shall be considered the outer or outward end of these elements.
