D. MARINSKY STRINGER TAPE Filed March 6, 1937 INVENTOR fi/zv/a Mil/Y5K) ORNE? BY I Ah- Patented Aug. 22, 1939 UNITED STATES PATENT OFFICE STRINGER TAPE Davis Marinsky, Bronx, N. Y., assignor to Whitehall Patents Corporation, Bronx, N. Y., a corporation of New York Application March 6, 1937, Serial No. 129,320

2 Claims.

' tapes through the apertured portions thereof and inwardly of one longitudinal edge of the tape so as to provide a secure attachment of the links to the tape; a. further object being to provide a stringer tape of the class described fashioned from a single woven fabric body wherein'one edge portion of the tape is enlarged or beaded and wherein said beaded edge joins the remainder of the tape in widely spaced threads, the thickness of which is less than the width of the links or coupling elements to be attached to the tape whereby in die casting the links on the tape, the inner ends thereof will be united through the tape inwardly ofsaid beaded edge and between the spaced threads or strands; astill further object being to provide a stringer tape of the class scoops with the stringer tape; and with these and other-objects in view, the invention consists in a device of the class and for the purpose specified, which is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a plan view of a part of two stringers of a separable fastener showing my improved mounting tape or tapes.

Fig. 2 is a transverse sectional view of the structure shown in Fig. 1.

Fig. 3 is a plan view of the stringer tape or mounting member detached.

Fig. 4 is an enlarged sectional view similar to Fig. 2 showing only a part of the construction and showing a. modification; I

Fig. 5 is a view similar to Fig. 4 showing another modification and,

Fig. 6 is a plan view of a part of the construction shown in Fig. 5.

In Figs. 1 and 2 of the drawing, I'have shown at 5 and 5a the tapes or mounting members of a separable fastener stringer including the coupling links or scoops 6, 6a attached to'one enlarged or beaded. edge 1, 1a of the

tapes

5, 5a. The separable fastener is of the type employing a slider movable along the stringers or the links 6, 6a thereof to couple and uncouple said links in the operation of attaching and detaching the fastener as in other devices of this kind, but the slider and other associated parts are 'omitted as they form no direct part of the invention.

Asthe tapes

5, 5a are of similar construction, the brief description of one will apply to the other. In Fig. 3 of the drawing, I have shown the tape 5 detached and this tape consists of a single unitary woven fabric having a wide attaching end portion 8 inwardly of the beaded edge I thereof. The beaded edge joins the part 8 in widely spaced strands 9 which are, in the construction shown,

part of the cross or weft threads of the fabric. These threads form longitudinally spaced and relatively large apertures or openings I0 in close proximity to the beaded edge I. The size of the threads 9 is less than the width as well as thick ness of the link 6 to be attached thereto so as to establish a complete bonding or uniting of each link through at least one of the apertures 10 as indicated at H in Fig. 2 of the drawing, and especially when the link 6 and its companion link 6a is composed of a casting or die cast body. However, as seen in Fig. 4 of the drawing, the link 6b may have a forked inner end l2 which is brought together within the openings ill in the strip 5. These forked ends may simply be brought together by suitable pinching tools, or, if desired, may be cemented together or otherwise secured together as indicated at 13 in said figure so as to produce substantially the same result as that shown in Fig. 2 of the drawing.

While my improvedtape is adapted for use in any type or. kind of stringer construction or employing links of many types and kinds, it finds I its principal use in conjunction with the nonmetallic plastic or thermoplastic links, and still more particularly to links composed of cellulose acetate which may be directly die cast upon the tape or individually cast and then formed and cemented as seen in Fig. 4 of the drawing. With these types of links, the

tapes

5, 5a may be exposed to or passed through a solvent solution such for example as acetone, whichby capillary attraction will quickly extend to the links attached to the beaded edge of the stringer and operate to cement and secure the links to the beaded edge as well as to any part of the tape including the threads or strands S'thereof contacting with said links in a manner taught more specifically in a companion application filed March 6, 1937, Ser. No. 129,317.

Upon a consideration of Fig. 1 of the drawing, it will appear that the spacing of the threads 9 and the size of the apertures III is such as to provide a staggered or more or less indefinite location of the links 6, Ba. with respect thereto and this would depend largely upon the size of the links employed on the tape as well as the number of strands 8 or the spacing thereof deemed necessary to provide the required strength in the resulting tape. But, due to the fact that the strands 9 will be, at all times, less in size than the dimensions of the link, a. bonding of the link through the apertures formed between the strands will be assured regardless of the spaced arrangement thereof.

In Figs. and 6 of the drawing, I have shown another modification wherein a supplemental mounting tape I4 is employed in conjunction with a tape 5, similar to the tape 5 shown in Figs. 1 and 3, the tape l4 consisting of similar side portions 15, l5a joined by an intermediate openwork or apertured section l6 formed by removing a number of the longitudinal threads in the weave of the strip ll so as to permit the section Hi to slip over the protruding ends of the links 6 and to pass around the beaded edge I and to be stitched or otherwise secured to the tape 5 adjacent the links 6 as indicated at H.

.The supplemental strip l4 may be attached after the stringer tape has been treated with the saturating solution of the solvent employed to secure the links in position, or this treatment may take place after the attachment of the supplemental strip if desired.

In fastener stringers of the kind under conopen or forked inner end of a link may be brought together in the apertured portion to substantially completely envelop the beaded edge of the tape or these ends may be cemented together to produce a more or less unitary coupling body around said beaded edge. This will make the links as strong as the tape or substantially so, depending entirely upon the material employed in constructing the links.

In the above described operation of cementing the links to the stringer tapes either as shown in Figs. 1 and 2 or as shown in Fig. 5, slight pressure may be applied to the links in the cementing or gluing operation to insure positive engagement of the links with the fibres of the tape and to compensate for the softening of the surfaces of the link adjacent the tape by exposure to the solvent employed. However, this applied pressure is only essential where the fastener is to be subjected to excessive stresses or strains in the article or garment to which it is attached.

Having fully described my invention, what I claim as new and.desire to secure by Letters Patent, is:

1. In a separable slide fastener, a tape having a head at one edge thereof, a plurality of coupling links mounted on said bead and uniformly spaced thereon, said tape and bead being connected together by spaced substantially parallel strands, each strand being of less thickness, as measured lengthwise of the tape, than that of one of said links, whereby at least part of each link will pass through a space between adjacent strands, regardless of the position of that link relative to a strand, certain of said strands being at least partially covered by certain links.

2. In a separable slide fastener, a tape having a bead at one edge thereof, a plurality of coupling links cast on said head and uniformly spaced thereon, said tape and bead being connected together by spaced substantially parallel strands, each strand being of less thickness, as measured lengthwise of the tape, than that of one of said links, whereby at least part of each link will pass through a space between adjacent strands, regardless of the position of that link relative to a strand, certain of said strands bein at least partially covered by certain links.
