FOR. THERMOPLASTIC FASTENERS Davis Marinsky, Bronx, N. Y., assignor to White hall Patents Corporation, Bronx, N. Y., a corporation of New York Application March 6,
1937, Serial No. 129,316
Renewed February 7-, 1940 3 Claims.
This invention relates to separable fasteners employing linked stringers adapted to be coupled and uncoupled by a slider movable longitudinally of the links of said stringer in coupling and uncoupling the same and particularly to the formation of end stops at the ends of the stringers to limit the travel of the slider thereon; and the object of the invention is to provide the ends of the stringers with stops formed entirely or partially by the links employedin forming the stringers so as to produce a simple and economical construction as well as a neat and finished appearance on the resulting fastener; a further object being to provide an end stop construction for fastener stringers which is made in accordance with the method morefully hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the several parts of my invention are designated by suitable reference characters in each of the-views, and in which:
Fig. 1 is a plan view of a fastener made according to my invention, with part of the construction broken away.
Fig. 2 is a detail view of one end of a fastener stringer diagrammatically illustrating the method of stacking or launching links thereon.
Fig. 3 is an enlarged detailedge view of one stringer, diagrammatically showing the method of securing the bunched or stacked links together, said figure being a view substantially looking in the direction of the arrows 3-3 of Fig. 1.
Fig. 4 is a partial section on the line 4-4 of Fig. 1, showing the other end stop which I employ; and,
Fig. 5 is a view similar to Fig. 4 showing a modifled form of construction.
In Fig. 1 of the drawing, I have shown at I0 and II the stringers of a separable fastener having attached to the beaded edges l2 and i3 thereof a plurality of longitudinally spaced coupling links it and I5. At I6, I have shown a slider movable longitudinally of the links to couple and 5 uncouple the same, said slider having a finger piece or pull I l to facilitate the operation thereof. The links It and I in the construction shown are preferably made from a plastic or thermoplastic material, such for example as cellulose 50 acetate. These links may be clamped upon the stringer tapes I, II, or the beaded edges l2, l3 thereof or directly die cast thereon. It is pre-" ferred that the beaded edges have rayon or other strands I211, [3a extending longitudinally thereof 66 to contact the respective links to aid in securing or cementing the links to the stringers, especially when subjecting the stringer tapes to a saturating solution in the form of a solvent, such for example as acetone which, by capillary attraction, extends to the inner surfaces of the links where 5 they contact the tapes to form a cementing area between the links and tape. This structure and method is in accordance with the teachings in my companion application Serial No. 129,321, filed of equal date herewith. If desired, slight pressure may be applied to the links in the cementing operation as well as the application of heat sufflcient only to aid in setting or hardening the cement, all as taught in a companion application filed of equal date herewith.
In the operation of forming my improved stringers or the end stops at the ends of said stringers, each stringer tape is formed in the conventional manner with all of the links l4-l 5 applied thereto in an equally spaced manner. ,The first step in forming end stops ill at one end of the stringer is as follows. Four of the end links are forced longitudinally of the stringer tape by a suitable fork-shaped tool l9 as indicated in Fig. 2 of the drawing in which the links M are shown on the tape l 0. This operation is performed after acetone or slight heat has been applied to said four links to soften the same sufliciently to provide free action or sliding movement longitudinally of the beaded edge I! of the tape, and
- especially in the case of die cast links which are applied to said tapes. When these links are brought into the stacked or piled relationship with the projecting beads lBa of the links extending into recesses on the opposed surface of adjacent links, said links are then secured together by applying a suitable cement or solvent thereto, for example, by spraying a cement or solvent such as acetone in the manner indicated at 20 in Fig. 3 of the drawing to one or both side surfaces of the links, and then allowing the solvent or cement to dry. If desired, slight pressure may be applied to the links in this operation. However, if all of the links are to be cemented to the tapes In as above stated, the pressing operation may be performed in the aforesaid cementing operation. All of the stacked or grouped links forming the end stops l8, in addition to being cemented together on adjacent abutting surfaces, will also be cemented to the tape I 0 or the beaded edge thereof.
In the accompanying drawing, the end stop l8 on the stringer ill consists of five links, whereas the stop It on the stringer ll consists of four links, but this is simply to provide a balanced 55 finished end to the complete stringer. But, if desired, any number of the-links may be provided, it'being understood that two links Joined on each stringer will block or stop further progress of the slider along the stringers. With the present construction, the slider I6 is capable of extending the full length of the stringers or to a point in alinement with th outer link of each stop l8, or substantially so.
End stops such as I8 will provide a neat and finished-appearance to one end of the stringers, and a uniform construction will be provided throughout the entire stringer in so far as the link and end stop I8 is concerned. The same result or substantially the same result can also be accomplished at the other end of the stringers by simply providing a stop plate or sheet 2| of cellulose acetate or similar material, preferably of a color consistent with that of the color employed in the links H and l5.
This plate 2| is arranged upon a number of the interlocked end links 22 of the stringers l and II and is secured thereto by a cement or adhesive 23 such for example as acetone which may first be spread onto the coupled links 22 and onto one surface of the plate 2|, and then said plate attached or mounted in position in the manner shown in Fig. 1 of the drawing and slight pressure may be applied to secure and retain the plate 2| in position, and this may be done in the presence of heat if desired.
' In Fig. 5 of the drawing,'I have shown a modi-.
fication which consists simply in including a supplemental stop plate 2 la at the lower surface of the stringers to provide a double stop. The plate 2|a is secured in position at the same time that the plate 2| is secured or directly thereafter as may be desired. By using acetone or cellulose acetate fasteners a substantial weld is provided between the parts secured together which provides a strong and durable construction. Thus, it will be seen that a very simple and economical form of end stop is provided for both ends of the stringers while at the same time eliminating the use of metallic parts or parts of complicated construction, thus materially reducing the cost of manufacture of the complete device.
The slider l6 as well as the pull l'l may also be composed of plastic material of the type and kind under consideration, but these members form no specific part of the present invention.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is:
1. In separable fasteners of the class described employing a fibrous stringer tape having thermoplastic links attached to one edge thereof and spaced longitudinally of the stringer, means forming an end stop at one end of the stringer, sand means comprising a plurality of links arranged in nesting and abutting relationship one with respect to the other and secured together by a solvent for said links, said stringer being saturated with the solvent to cement that part of the links engaging the stringer against displacement therefrom, that part of the stringer to which the links are attached having an enlarged beaded edge, and said beaded edge including rayon strands interwoven with the fabric thereof.
2. In separable fasteners of the class described, a stringer tape composed of fibrous material, thermoplastic links attached to one edge thereof and spaced longitudinally of the tape, a rayon thread arranged longitudinally of said edge of the tape and exposed therethrough to contact each of said links, a solvent for said links and thread applied thereto in securely cementing the links to said edge of the tape, and a plurality'of links at one end of the stringer tape being arranged one upon the other and secured together to form an end stop.
3. In separable fasteners of the class described employing stringer tapes and thermoplastic coupling links spaced longitudinally of the tapes and adapted to be coupled and uncoupled, rayon threads extending longitudinally of that portion of the tapes to which the links are attached and contacting said links to aid in securing all of the links to said tapes, a solvent for said links and threads applied to the tapes in securing the links thereof, and predetermined end links of the tapes being arranged in nesting and abutting relationship and secured together and to said tapes by said solvent.
