This invention relates to fasteners and more from plastic material throughout which willgreatly enhance its beauty as well as add to comfort in its use for clothing. The invention also provides a fastener which incorporates the security of a button and buttonhole fastening means with the ease and rapidity of operation of a slide fastener. Another object of the invention is the provision of a fastener which when fastened will have all parts concealed and present to the eye only a smooth surface.

Still another object of the invention is to provide a fastener which, due to its construction and the type of material which may be'used therein, can be manufactured at extreme low cost.

With these and other objects in view, the invention resides in the arrangement and combination of parts hereinafter described and claimed, it

Fig. 2 is a plan view of astrip attached to the opposite side ofthe closure;

Fig. 3 is a plan view of assembled parts of the invention with a slide in place, the slide having its top broken away;

Fig. 4 is a horizontal sectional view of Fig. 3; Fig. 5 is a section of the line 5-5 of Fig. 3; Fig. 6 is a section on the line 6-6 of Fig. 3; Fig. 'l is a section on the line l-'l of Fig. 2; Fig. 8 is a modified form of the fastening strip shown in Fig. 2; and

Fig. 9 is a transverse section through a fastener using the modified form of strip shown in Fig. 8.

Referring to the drawings in detail, the inveni5 tion contemplates the use of a series of buttonsor projections secured to one free edge of the closure and a series of openings or buttonholes in the opposite free edge of the closure adapted to cooperate with the projections. In Fig. 1 is shown 50 a flexible cord I having at spaced intervals enlargements 2. The cord on both sides of the enlargements is drawn together underneath the enlargements and stitched, or otherwise secured, to a tape 3, as shown in Fig. 4 thus leaving the t5 enlargements free and projecting beyond the tape m4, Serial No. man (chat-eta) tofonn the buttons above referred to. The buttons are thus freely rotatable about their point of support on the tape.

The opposite free edge of the closure consists of a strip of material such as ordinary cloth or fabric 4 folded'upon itself down its full length with its free or open edges presented toward the button-like projections or enlargements 2. Intermediate its edges, the folded portions of the strip 4 are intermittentlystitched together, leaving free portions between the stitches which form nonextensible openings or buttonholes 5, clearly shown in Fig. 7. Secured to the strip 4 with this same stitching are lengths of headings 8, one upon either side of the strip.

In closing the fastener, the enlargements or buttons 2 enter the openings 5 and lie behind the stitching. This is brought about by the .use of a slide 1 which, although similar to the ordinary fastener slide well known in the art, diflers therefrom in several very important details. It will be noticed that the body portion, or separator 8, of the slide is placed to one side of the center thus leaving a greater space upon one side than u n the other. Cut along one side of the body po on of the slide is a groove 9 to receive and guide the enlargedportions 2, and formed upon the opposite side is a tongue Ill, V-shaped in cross section and adapted to run between and separate the free edges of the flexible strip 4,

and thereby facilitate entrance of the buttons 2 into the openings 5.

The coverplates l I of the slide are provided with the usual guide flanges l2 and I3, flanges l2 serving in conjunction with the groove 9 to engage and guide the buttons 2, and flanges l8 guiding the strip 4 through contact with the beading 0. To engage within the openings 5, the buttons 2 must enter the openings at an angle, and when within the openings tilt sharply at a reverse angle and drop back into place, the ends of the buttons overlapping the stitching of the strip 4. This is accomplished by employing a peculiarly shaped snout upon the leading edge of the slide. The flanges I3 of the slide after following a slow curvature for the greater part of their length, break sharply in a reverse curve as at M. The bead 6 following the slow curvature of the flange will diuntil the cord support of each button approaches the stitching or end of the button hole which lies toward the closed portion of the fastener. At this point the end of the button which is in the button hole reaches the flange I3, which due to its particular conformation in conjunction with the flange I2 turns or rotates the button about its cord support on the tape 3 so that its opposite end will pass through the opening 5 to fall in place behind the stitching.

Movement of the slide in a reverse direction reverses this action and causes the two sides of the closure to separate. It is contemplated that all parts of this fastener, with the exception of the slide, may be spun from some plastic material such as cellulose compound or the like. However, it may also be made using intermixed metal and flexible material.

Figs. 8 and 9 show a different method of securing the folds of the strip 4 together which comprises the use of rivets, staples, orthe like, as at l5; when this method is employed, the rivets 15 in cooperation with the flanges l3 guide the strip 4 within the slide.

Having this described my invention, what I claim is:

with the enlargements free from and projecting from said edge to form a series of button-like projections, a strip of material folded upon itself throughout its length secured to the other free edge, the folds of the strip being stitched intermittently to form a series of openings adapted to receive said projections and a slide to introduce the projections within the openings, or to remove them therefrom.

2. In a device of the character described, a cord having enlargements at spaced intervals thereon,

said cord being secured to .one free edge of the.

- closure with the enlargements free from and projecting from said edge to form a series of buttonlike projections, a strip of material folded upon itself throughout its length secured to the other free edge, the folds of this strip being stitched intermittently to form a series of openings adapted to receive said projections, a slide to introduce the projections within the openings, means carried by the slide to run between the folds of said strip to separate the edges and facilitate entrance of the projections within the openings, and means carried by the strip to act as a guide within the slide. a

3. In a closing device in combination a flexible strip having spaced non-extensible buttonholes, a second flexible strip, elongated buttons on the second strip spaced to correspond with the buttonholes, said buttons being pivotally supported substantially midway between their ends, and a slider for progressively inserting the elongated buttons endwise into the buttonholes and rotating the buttons about their supports.

4. A closure means comprising in combination a flexible strip having a row of spaced non-extensible buttonholes, a second flexible strip having a row of correspondingly spaced buttons pivotally supported thereon and a slider embracing the rows for progressively inserting the buttons in the buttonholes and rotating them with respect to the buttonholes.

5. A closure means comprising in combination a flexible strip having a row of spaced non-extensible buttonholes, a second flexible strip having a row of correspondingly spaced buttons pivotally supported thereon and a slider embracing the rows for progressively inserting the buttons in the buttonholes and rotating them with respect to the buttonholes, said slider including a pair of cams for guiding the buttons along a curved path into the buttonholes and turning each button with respect to its buttonhole.

6. A closure means comprising in combination a flexible strip having a row of spaced non-extensible buttonholes, a second flexible strip having a row of correspondingly spaced buttons pivotally supported thereon and a slider embracing the rows for progressively removing the buttons from the buttonholes, said slider including a pair of cams for progressively turning each button within its buttonhole and withdrawing it from the buttonhole.

7. A closure means comprising a pair of flexible superimposed layers secured together at intervals to provide a row of spaced buttonholes between the layers, a flexible strip having a row of buttons supported thereon at spaced intervals to correspond with the buttonholes, and a slider embracing said strip and layers for guiding the buttons between the layers and into the buttonholes.

8. A closure means comprising in combination a pair of flexible superimposed layers secured together at intervals to provide a row of spaced buttonholes between the layers, a flexible strip having a row of buttons supported thereon at spaced intervals to correspond with the buttonholes and a slider embracing the strip and layers for joining the strip to the layer, including means for separating the edges of the layers and means for guiding the buttons between the separated edges and into the buttonholes.

9. A closure as defined in claim 7, in which means project from the layers to form a guide for the slider.

10. A closure as defined in claim '7, in which the layers are secured together by rivets and the heads of the rivets form the guiding means for the slider.

11. A closure as defined in claim '7, in which the buttons project from the edge of the strip.
