2 Claims.

My invention aims to provide improvements in multiple operated fastener closures and particularly improvements in end stops to limit the movement of the slider in one direction. In the drawing which illustrates preferred embodiments of my inventionz- Figure 1 is a plan view of one end of a pair of stringers closed by multiple operated fasteners, my improved stop members and a slider being shown in cross-section;

Fig. 2 is a .view of the parts shown in Figure 1 but showing the stringers partially separated;

Fig. 3 is an enlarged section taken on the line 3-3 of Figure 1;

Figs. 4 and 5 show opposite edge views of an end stop shown in Figs. 1 and 2 before attachment to a Stringer;

Fig. 6 is a view similar to that shown in Fig. 1 but showing slightly different stop members; and

Fig. 7 is a view similar to that shown in Fig. 6 but showing another type of stop member.

I am aware of the fact that stop members for use on stringers carrying multiple operated fasteners are broadly old for the purpose of preventing the slider from being moved clear of the fasteners. However, I am not aware of any prior stop members which are provided with means which tend to bring the edges of the stringers together at that side of the slider beyond the fastener members when the stop members are engaged by the slider. Therefore, my invention is particularly directed toward providing stop members for each of the stringers tol cooperate with the slider for closing an aperture. With the ordinary type of stop members designed solely for the purpose of stops there is usually a substantial opening between the stringers beyond the slider when the fasteners are engaged. This is objectionable in connection with pocketbooks,

pockets, bags and the like where small articles contained in the device could fall out and become lost.

Referring rst to all of the figures of the drawing in order thatllike parts may have like numerals, I have illustrated multiple operated fastening means comprising a pair of stringers 1-1 of usual construction having beads 2`2 on adi jacent edges. 'I'he beaded edges have separable fasteners 3 of suitable construction secured thereto and adapted to be'engaged and disengaged by longitudinal movement of a suitable slider 4.

The slider is constructed to engage the fasteners at opposite faces of the stringers and has two halves connected at one end by a cross-piece 5 65V which extends between the stringers. This cross-piece 5 is narrow and divides one end o! the slider into two openings through'which the fasteners 3 pass as the slider is moved over them by the pull tab 6 (Fig. 2) loosely secured to the slider in the usual manner.

. In order that the slider may not be pulled beyond the ends of the fasteners at one end of the stringers during the closing operation, I have provided on each Stringer 1 adjacent to the end of a row of fasteners 3 a. stop member prefer- 55 ably formed from sheet metal.

The stop members shown in Figs. 1 through 5 are each formed from a single piece of metal bent into a lll-shaped cross-section and having two` fiat portions 'I and 8 connected adjacent to one 70 end by a portion 9, as best shown in Figs. 4 and 5. These stop members are secured to the stringers 1-1, as shown in Figs. 2 and 3, so that the material of the stringers is clamped between the portions '7 and 8. The inner edges 10 of each 75 of the stop members Vdiverge relative to each other as do the outer edges 11 above the connectingV portion 9, thereby providing edges which are angled relative to the edges of the stringers and engage with the slider when they '30 are pulled into the slider, as shown in Fig. 1. At their upper ends the portions 7 and 8 may be horn-shaped and have their ends terminating behind the beads 2.

When stops of the type shown in Figs. 1 '35 through 5 are pulled into the openings in the upper end of the slider between the cross-piece 5 they are rst engaged at their inner edges 10 by the edges 12 of the slider. Thereafter the edges 11 engage the cross-piece and further at- @o tempts to pull the stop members into the slider result in the stops being tipped about their points of engagement with the cross-piece 5, because of the shape of the stops. The result of this tipping action is to force the ends 13-13 of the stop '95 members toward each other, thereby forcing the beads 2-2 of the stringers 1 1 against each other and substantially close the stringers above the slider, as shown Figure 1.

In Fig. 6 I have shown stop members which do '1 not have the horn portions but in all other respects are substantially the same in construetion and operation as the stop members deflned above. These stop members tip in/ the same manner as those with the horns and thereby have a tendency to push the stringers toward each other above the slider.

In Fig. 7 I have shown stop members which ar'e similar to those shown and described in connection with Figs. 1 through 5. 'In this case, how- 110 ever, the "horny are made in such. a marmer that they have their ends lei-1li extending over the beads 2--2 and clamped thereagainst. These ends 14-14 terminate at the edges of the stringere i-l so that they may abut as illustrated and thus securely close the stringers above the slider.4

My improved stop members overcome the difiiculties of other known stop members to a remarkable degree and therefore have been found highly desirable as a commercial article which is simple, durable and easy to apply.

While I have illustrated and described preierredembodiments of my invention, I do not wish to be limited thereby, because the scope of my invention is best dened by the following claims.

I claim:

1. In a multiple operated fastening device having two stringers each having a series ofv fastening elements attached to one edge, a slider for engaging and disengaging the fasteners at the edges of the stringers as desired and stop members secured to said stringers at one end thereof adjacent to the fastening elements to limit the movement of said slider in one direction, each of said stop members having a wedges Stringer-dosing portion not entering thesiider but which is adapted to move one Stringer toward the other substantially to close the said stringere beyond one end of the slider and cam means provided by said stop members at both the inner and outer edges thereof, said cam means being angled relative to the edge of the Stringer and cooperating with said slider to actuate the Stringer closing portions of said stop members. l

.2. In a multiple operated fastening device having two stringers each having a series of fastening elements attached to one edge, a slider for engaging and disengaging the fasteners at the edges of the stringers as desired and sheet metal stop members secured to said stringers at ane end thereof adjacent to the fastening elements to limit the movement of said slider in one direction, each of said stop members having inner edges which diverge with relation to each other, said diverging edges cooperating with the slider and portions of said stop' members beyond the diverging `edges adapted to be operated by the cooperation between said diverging edges and said slider to force said stop members substantially to close said stringere beyond one end of said slider. v
