Fig. 18 is a view similar to Fig. 1'? but showing the position of the parts of the end stop of Figs. 14
, to 17 when locked to the stringer tapes of a slide fastener. J
Theslide fastener, of which a fragment is shown in Fig. 1, comprises a righthand stringer 2| and a-lefthand stringer 22 each of which stringers comprises a flexible textile or other tape 23 provided at it inner edge, in conventional manner, with an edge reinforcement 2 A row of predeterminedly equally spaced scoops or interlocking members 25 is secured to each tape edge reinforcement 24. These scoops are progressively engaged and disengaged, in conventional manner, by a slider (not shown). This slider is supported on these rows of scoops for movement thereon upwardly and downwardly for this purpose. This structure, as shown, is conventional.
Below the lowermost scoop 25,.the stringers 2| and 22 areconnected by one preferred form of bottom end stop formed and applied according to this invention and'generally designated 26 in Fig. 1. The details of this end stop 26, the blank from which it is formed, and the method of forming and attaching it to the stringer tapes are .illustrated inFig-s. l, to 10,, inclusive.
The end stop 26 comprises a front wing 21 with inturned side flanges 28 which confine the tape edge reinforcements at one side of the stringer 5 tapes 23 (Fig. 2) and a similar obverse rear wing 29 with similar side flanges 33 confining the edge reinforcements 2:; at the opposite side, these Y wings being connected by an integral neck 3| extending from the lower edge of the rear wing 29 to the upper edge of the front wing 21. A looking strap or retainer member .32 extends forwardly from the upper edge of the rear wing 29 and terminates in a flange 33 adapted to engage the upper edge portion of the front wing 21 to lock the wings 27- and 29 clampingly to the stringers 2| and 22 (see Figs. 2, 3 and Preferably, each of the wings 21 and 29 is provided with a pair of lateral-1y Spaced downwardly and inwardly directed barbs 34 struck out therefrom and adapted to penetrate the tape edge reinforcements 24, as shown in Figs. 1, 3 and 10. If desired, however, the barbs 34 may be omitted from one wing, as shown in Figs. 11 and 12.
It is preferred that these barbs 34 be struck out from the wings in the flat as indicated. by the blanks shown in Figs. 4 and 5, in order that the application of the end stop 26 to the stringers 2| and 22 be entirely manual; however, as shown in Fig. 13, the barbs 34 may be struck out of one or both of the wings by suitably laterally spaced pairs of opposed punches 35 after attachment of the end stop 23 to the stringers 2| and 22.
A modified form of end stop is illustrated in :Figs. 14 to 18 and is therein generally designated 26a. This end stop is similar to that form illustrated in Figs. 1 to 13, inclusive, save that it is provided with a second locking strap or retainer member 32a similar to the above described member 32 and terminating in a flange 33a similar to the above described flange 33. This member 32a extends re'arwardly from the lower edge of the front wing 21 and its flange 33a engages the lower edge portion of the rear wing 29 as shown in Fig. 18. In this modified form, the rigidity of the ats tached andlocked end stop 26a is somewhat enhanced over the form shown in Figs. 1 to 13, inclusive, by the additional connection provided between the wings 2! and 23 by the strap connector member 32a.
'In order to facilitate attachment of the form of end stop shown in Figs. 1 to 13., inclusive,.I have provided a tool 36 of which a fragmentary showing is made in Figs. 8 and 9. This toolcomprises an elongated bar preferably of width equal to, or less than, the width of the neck 3| and the member 32. A slot 31 terminates at its outer upper corner in a depending projection 38 adapted to engage the outer surface of the front wing 21. This slot 3! also defines the upper inclined edge of the triangular projection 39 which engages and spreads the wing 2'! and the tongue 3| upon exertion of thrust upwardly of stringers 2| and 22 to provide the necessary wing clearance for relatively free movement of the end stop 26 upwardly with respect to the fastener, as shown in Fig. 9.
In forming the end stop of Figs. 1 to 10, a blank as shown in Fig. 4 is stamped or cut out from a flat sheet of resilient sheet material such as steel or other suitable metal. This blank comprises the front wing portion 2'! and similar rear wing portion 29 connected by the integral neck portion 3|. The strap or retainer portion 32 extends outwardly from the free edge of one of the 7-,;
4 wing members in substantial alignment with the neck portion 3|.
The wing portions are wider than the wings of the finished end stop by an amount equalling the width of the side flanges 28 and 3D and the strap or retainer member 32 is longer than the strap or retainer of the end stop by an amount equalling the width of the retainer flange 33.
As shown in Fig. 5, in the next step the side flanges 28 are bent or struck downwardly, and the side flanges 33 and retainer flange 33 are bent or struck upwardly. The barbs 34 may, optionally, be simultaneously struck out, downwardly from the wing portion 21, and upwardly from the wing portion 23. Of course, in the form illustrated Figs. '11 and 12', the barbs 34 .are omitted from one wing portion.
Likewise, as illustrated in Fig. 13, the striking out of the barbs 33 may be entirely omitted from the above described step and deferred until after the end stop is attached to the slide fastener stringers.
After the blank has :been bent in the fiat as shown in Fig. 5, or as described above, it is bent along the junction of the neck 3| and the wings 2 and 29 substantially to the Z-section form shown in Fig. 6. In'this state, the wings are disposed closer than in their final position when the end stop is attachedto the stringers (Figs. 1., 2 and 3) whereby, when they are in their finalposi- 'tion, they clampingly engage the stringer tapes with substantial force.
In order to facilitate manual positioning of the end stop upon the stringer tapes, the wings must be more widely spread than in Fig. 6. For this purpose I utilize the strap member 32 as a prop or spreader.
In order to .pre-stress the membe 32 for this purpose and also to insure that it shall remain snugly in position as shown in Figs. 3 and 10, the wing members 2-! and 2-9 .are temporarily forced apart to facilitate bending of the strap member 32 toward the wing member 29 to an acute angle as shown in Fig. 7.
When the Wing members 2.! and '29 are thereafter released the. parts take substantially the position of Fig. 8 wherein the upper ends of the wing members are spread apart a distance greater than the tape thickness. The end stop. ma be then manually and threadedl forced upwardly on the tapes since the barbs 34 extend downwarlly and will :not dig intothe edge reinforcements as they move upwardly over them.
When the end stop 26 in. the form of Fig. 8 has been moved upwardly until it engages the lowermost scoop .25, it may be moved or forced downwardly of the tapes suiiiciently to set it on the tapes by reason. of the, penetration of the edge reinforcements by the barbs 34 which, thereafter, effectively prevent relative movement between the end stop and the supporting tapes.
As shown in Fig. 11, the omission of barbs from the front wing 21 facilitates, manual attachment although the security ofattachment isdependent entirely upon the barbs 34 of the rear wing 29.
As shown in Fig. 13, and as pointed out above, the barbs 33 may be omitted from both wings 2-7 and 29 before attachment for utmost facility of manual attachment. In such case the barbs are struck out by'opposed dies after attachment of the-end-stop 26 t o -thestringer tapes.
As an alternative, as shown in Figs. 14 to. 18, the end stop may be provided with straps or retainers, 32 and 32a, at both ends. Such provision facilitates manual threaded attachment as shown in Fig. 1'? since the two props provided bythe members 32 and 32a maintain the wings 21 and 29 parallel and sufficiently widely spaced to permit this manual placement without interference from thebarbs 34. l I
The end stop of this embodiment is formed from a flat blank similar to thatof Fig. 4 but provided with strap portions at both ends, the respective flanges being bent or struck up and down as shown in Fig. 14 before the blank is bent as in Fig. 15, the wings spread as in Fig. 6 and the straps or retainers 32 and 32a bent as therein shown. Upon release of the spreading force the parts take the position shown in Fig. 1'7.
In either case, when the end stop is manually positioned on the tape as shown in Figs. 9 and 17 wherein the retainer member 32, or retainer members 32 and 32a, prop or spread the wing members 21 and 29 apart, application of squeezing pressure to force the wings 21 and 29 together, manually or otherwise, will cause the retainer flanges 33, or 33 and 33a, to ride upon the engaged surface of the neck 3! as upon a track, until they pass over the bend or bends at the junction or junctions of the neck 3| with the adjacent wing or wings whereupon the flange 33 will snap over into the position of Figs. and 18 effectively to lock the wings together in predetermined clamping spaced relation.
It is, of course, to be understood that the above description is merely illustrative and in nowise limiting and that I'desire to comprehend within my invention such modificationsas is included within the scope of the appended claims.
Having thus fully described my invention, what I claim and desire to secure by Letters Patent is:
