1Claim.

The present invention relates to a closure or fastening means and more particularly to a closure of the slidable type, having two parallel cord-like members secured together for approximately one-half their length.

One of the objects of the invention is the construction of a slidable fastener which nds a ready application for use in conjunction with pocket bags, cloth cosmetic receptacles, handkerchief bags, sewing bags and, in fact, in any and al1 places where an easily operable closure or fastening means is desired.

Still another aim of the invention is the formation of a slidable fastener characterized by simplicity of structural detail and which may be readily applied to the various articles aforementioned. K f

Yet a further aim of the invention is the construction of a slidable closure entirely devoid of mechanical metal fastening means and in which the slotted guides or keepers may be readily attached by means of stitching with thread or by an adhesive, or the like..

Other aims and objects will be apparent from the detailed description hereinafter appearing when taken in conjunction with the appended drawings forming a part hereof, to which reference is now made, and in which:

Fig. l is a top plan view of one form of the novel slidable closure or fastener shown as unattached and which may be sold or merchandized as such for subsequent sewing or attachment to a bag or the like.

Fig. 2 is a sectional view taken on line 2--2 of Fig. l. Y

Fig. 3 is a side elevational view showing 'the slidable fastener or closure of Fig. l attached to a cloth cosmetic receptacle.

Fig. 4 is a sectional view taken on line 4 4 of Fig. 3.

Fig. 5 is an elevational view similar to that of Fig. 3 but showing a mcdied form of the slidable closure.

Fig. 6 is a detail view partly in section and partly broken away of the closure of Fig. 5, showing the manner of securing-,the slotted members or guides to the cloth receptacle.

Fig. l is a top plan view of` one of the novel bead-like slotted members or guides of the closure of Fig. 5.

Fig. 8 is a sectional view taken on line 8-8 of Fig. '1.

Fig. 9 is an elevational view similar to that of Fig. 5, but showing still another modified form of the invention.

Fig. 10 is asectional view taken on the line Illi0 of Fig. 9,.

Referring first to Figs. 1 to 4 inclusive there is shown in Fig. 1 one form of the novel slidable closure generally designated as C. The closure comprises preferably a pair of parallel cord mem-- bers` IIl--II secured at their ends I3 and UIB. It will be understood that the Amembers I8 and II'do not have to be made of yarn or the like and may also be constructed of wire or any other suitable material, preferably of a flexible character. The cord members I0 and II are secured intermediate their ends for approximately one-half their length, a length equal to the opening of a receptacle, by means of thread 15 stitching I4. The other half of the cord members are unattached as indicated at I5 in Fig. 3 of the drawings. A plurality of cylindricallyshaped keepers or guides I6 are secured in spaced relationship to the edges of cloth strips I1-I8. 2 As indicated in Fig. 2 the strips are folded upon themselves and the guides I6 are secured within the'folded portions of the strips Iii-2l) by means of an adhesive or the like. y From the construction shown in Fig. 2 it `will be appreciated that each of the bead-like guide members i6 is effectively covered by the folded portions Iii- 20 of the clothmembers Ill-I8, so as not to be materially exposed to view. By reference to Figs. 2 and 4 it will further be seen that each of l the bead-like guide members I6 is provided with a longitudinal slot 2I. The cords Ill and II are slidable in the keepers and, when the. cords are moved to the right as viewed in Fig. 1, the keepers I6 will be drawn toward each other with the 35 stitching I4 passing through the slits 2l in said keepers. 'I'his forms an effective closure as will be understood, while the closure may be opened by 'movement of the cord members IIJ and II to the left, as viewed in Figs. l and 3. Parallel 40 lines of stitching 22-23 serve to keep the folded portions Ill-20 of the cloth sections I1-I il together. The closure C may be attached to a cosmetic receptacle or bag 25 by means of stitching the cloth strips I1 and I8 to the folded edges 26 and 21 of the receptacle 25, the lines of parallel stitching being designated by the reference numerals 28 and 28.

Referring no'w to Figs. 5, 6, 7 and 8 of the drawings, there is shown a modified form of the invention, in which each of the cylindricallyshaped, bead-like members 36 is provided with a pair of spaced apertures 31--38 in the plane of the longitudinal slot 39- of the bead-like guide' member 36. The members 36 are secured to the folded edge'll of a receptacle 45 by means oi' stitching 4| passing through the spaced apertures 31 and 38, the stitching taking the form 0f a chain, as will be apparent.i'rom an inspection ofFig. 6 of the drawings. As will be seen each of the edges dening the opening in the closure member 25 is provided longitudinally thereof with guide members 35 so that when the cords I! and Il are moved to the right, as viewed in Fig. 5, the opening in the receptacle 45 will be closed by the stitching I4 and, when the cord members are moved to the left, the opening in the receptacle will be unfastened.

' -The construction of Fig. 9 is similar to that of Fig. 5, only in this instance, the bead-like guides 36 are alternately arranged on the opposed edges of the receptacle 25, the members kI5 being secured to the edge of one side wall 5I of` the receptacle 45 while, on the other edge 5I, the members 36 are secured slightly below the edge and inwardly toward the edge of the receptacle 45. 'I'he latter construction may be used on bags or other receptacles where a somewhat cheaper construction is not detrimental.

From the above description it will be appreciated that there has been provideda slidable clo- -sure of great simplicity and which is yet very effective for the purpose contemplated. No metallic fastening means are employed. the beadlike members being secured either directly to x receptacle or to cloth strips which may be sewed to the receptacle by means o! either an adhesive or'simple thread stitching. The bead-like guide members may be made of hard rubber, Celluloid, glass, Bakelite, or of any suitable material.

It will be yapparent to those skilled in the art that various modiilcations may be made to fall within the spirit of the invention, and it is contemplated to cover all such and to be limited vin this respect only as may be necessary by the scope of the claim hereto appended.-

What I claim is:

A slidable fastener comprising opposed edges defining a closure opening, a plurality of spaced .guides secured to each of said edges with the guides alternately arranged on said edges, each of said guides consisting of ayhollow cylindrical member opened at opposed sends and having a longitudinal slot connecting said ends and each guide having an opening in the plane of said slot, the securing means for said guides comprising a chain oi' stitching extending through the openings in said guides and through said edges. a cordl slidable in each set 0i' the guides, said cords being stitched together for a portion of their length.
