3 Claims.

This invention relates to closures, of the type adapted for use with purses, cosmetic bags, tobacco pouches and the like, as well as for wearing apparel such as shirts where it can be employed in place of buttons.

There are various closure devices for similar purposes, such as interlocking slide fasteners, and those comprising a plurality of spaced elements attached together by suitable linkage and slidably mounted over adjacent beads or rails. The former, although efiicient, are relatively expensive and of a definite and fixed configuration generally not considered very ornamental; and the known types of the latter, to which class my invention belongs, although adaptable to ornamental design, have laterally exposed chains, and do not efiect a close sealing, particularly along the spaced intervals between the slidable elements unless there isa superimposition of one of said rails upon the other, and a. consequent bending or distortion thereof. It is hence an object of my invention to improve over the known art by enabling a simple, inexpensive device of this class, capable of ornamentation, and consisting -of a. number of spaced slidable elements, to effectively bring into contiguous juxtaposition adjacent beaded closure edges to produce a satisfactory seal. 7

Another object of this invention is to permit the slidable elements to be operatively movable with-a minimum of friction against the beaded edges upon which they are mounted.

Other objects, features and advantages will appear from the draw s and the description here- I inafter given.

Referring to the drawings,

Figure 12 illustrates still another form of shirt 5 closure, and

Figure 13 is an enlarged transverse section taken along line iii-I3 of Figure 12, showing the general configuration of a. duplex slide.

In the drawings, the bag i5 contains at the 10 opening thereof two adjacent, preferably semistifl closure beads or rails I6 and I! over which are mounted a plurality of movable elements or slides l8 and one fixed binding element I9. These slides, in their operative positions, as shown in 15 Figure 1, are in spaced relation, and are connected by the flexible link or chain suitably secured preferable to the centers of the slides l8 and the binding l9, and positioned longitudinally above the contacting edge of said beads. 20

In the preferredform of my invention, the slide contains retaining means for the chain integral therewith, including the lower supporting a wall 2| pressed downwardly from the middle of -the slide into the space 22 between the tops of the beads. This supporting wall cooperates with the upper side walls-23 and 24 to hold'the chain 20 therebetween, all of said walls being preferably compressed towards the chain to hold it against movement, 'as is-indicated in Figure 3. The lateral sides 25 and 26 of the slides are inwardly curved as shown, so as to contact preferably with the lower portions of the beads I 6 and I1, and with the upper adjacent portions of the sides 21 and 28 of the bag to compress them together. The curved inden'ts at the bottoms of said lateral sides 25 and 26 are so formed and dimensioned as to be in pressing engagement with the underportions of the beads and with the sides ment therealong. The top or upper portion of 40 each slide may be spaced somewhat from the tops of the beads, as shown in Figure 4.

In the operation of this device, the elements 3 can be slidably moved along the beads l6 and II, to open or close the bag, the stationary binder l9 being immovably compressed at an end thereof. When the bag is in its closed position, sides 25 and 26 of the slides, being in pre'ssing engagementas hereinabove set forth, hold the heads in firm contiguous juxtaposition; and as these slides are frictionally held in place against movement, they will be enabled, in their spaced operative positions, to hold the chain 20 taut. Inasmuch as this chain is positioned over the G5 opening edge of the bag, it will serve as a further seal therealong to prevent the contents of the bag from dropping out when it is inverted, as might o'ccur between the slides if the chain were not present. For most efiective sealing, I prefer to use a relatively wide chain.

It will be noted that inasmuch as the slides need not be in contact with the upper portion of the beads, there is relatively little frictional resistance to sliding. Furthermore, such an arrangement avoids excessive wear along the top of the beads. Inasmuch as the supporting wall 2| is depressed downwardly and extends into the space 22, the chain 20 is supported at a relatively low level, and close to the top opening edge of the bag. It is also quite apparent that this form of closure is quite simple, the entire slide being formed from a single strip of metal.

In- Figures 5 and 6 is shown a modified form of slide 29 containing a centrally disposed transverse channel 30 pressed downwardly from the top of the slide to accommodate the chain 3|. The top of the channel is compressed together about the chain, to hold it against movement and to properly retain it in place. This is also an integral unitary member, the lateral sides thereof being similar to those of the said preferred form.

Figures '7 and 8 show another modification of the slide, the chain retaining elements being the overhanging walls 32 containing the holes 33 therein to accommodate the chain. And Figure 9 shows still another form of my invention, the slide consisting of two members, the slide proper 34 and the chain retaining element 35 the ends of which are inserted in suitable holes in the slide and compressed into place against the chain.

My invention is not only adaptable for use with bags and pouches, but is also applicable to wearing apparel, particularly in shirts and blouses of various kinds. By referring to Figure 10, it will be seen that the two parallel adjacent beads 36 and 31 attached to the shirt have slidably mounted thereover the slides 38 and the fixed binder 39, the slides being interconnected by the chain 40. The shirt can be opened by drawing the slides downwardly, as shown in Figure 11.

Another form of closure particularly applicable to shirts is that disclosed in Figures 12 and 13. Here the pieces of material 4| and .42 are not compressed together, but permitted to extend outwardlyin opposite directions, the duplex guide 43 operatively embracing both beads 44 and 45, the chain 46 being held into place by the retaining wall 41 pressing it against the body of the slide as shown. It is apparent that with this construction the two contiguous beads do not protrude an undue amount forwardly from the body of the shirt.

It is of course understood that the various embodiments above described and shown in the drawings are illustrative of my invention and not employed by way of limitation, inasmuch as numerous changes and modifications may be made within the scope of the appended claims without departing from the spirit of this invention.

What I claim is:

1. In combination with two adjacent longitudinal beads adapted for contiguous engagement to form a seal therealong, a clo'sure containing a plurality of elements slidably mounted over said beads and having chain retaining means each comprising a lower supporting wall pressed downwardly from the middle of the element above the line of engagement of the two beads, and two upper substantially flat side walls of the element flanking said supporting wall, and a chain extending above said supporting wall and below said side walls and compressed therebetween; said slidable elements each having two lateral sides with curved indents at the bottoms thereof in pressing engagement with the lateral and lower supporting means pressed downwardly therefrom, and a chain extending below the flat portions and above the said lower supporting means and compressed therebetween; said slidable elements each having two lateral sides with curved indents at the bottoms thereof in pressing engagement with the lateral sides and lower portions of the beads, the upper portion of each of said elements being out of engagement with the uppen portion of the beads.

3. In combination with two adjacent longitudinal beads adapted for contiguous engagement to form a seal therealong, closure means including a plurality of elements slidably mounted on said ,beads and having retaining means for a flexible connecting member above the line of engagement of the two beads, each member com-- prising a substantially flat top portion and supporting means pressed downwardly therefrom, and a flexible connecting member extending below the flat portions and above the supporting means of said members and compressed therebetween to secure said members to said flexible connecting member, said slidable elements each having sides with curved indents at one end thereof arranged, in pressing engagement with the sides and lower portions of the beads to hold the beads in contacting and sealed relation, the upper portion of each of said elements being out of engagement with the upper portions of the beads.
