ONE-SIDED SEPARABLE FASTENER STRINGER Filed July 12, 1960 INVENTOR.
Lou/5 hf Mom/v BY United States Patent 3,115,696 ONESllDlED SEPARABLE FASTENER STRINGER Louis H. Morin, 125 Beechwood Ave, Bronx, N.Y. Filed July 12, 1966, Ser. No. 42,398 14 Claims. (Cl. 24-2ll5.1)
This invention relates to separable fastener stringers employing sliders movable along the scoops of the stringers to couple and uncouple the same. More particularly, the invention deals with fasteners of this type and kind wherein the scoops in their entirety are disposed on one side surface only of the stringer tape and primarily adhered thereto by extension or" the casting material of the scoop into the interstices of the braid of the tape and, further, by engagement of the casting material with the beaded portion or portions on the surface of the tape, to which the scoops are attached.
Still more particularly, the invention deals with a fastener of the character described, wherein the arrangement of the scoops on the stringer tape is such as to bring edges of coupled stringer tapes into abutting engagement with each other when the stringers are coupled in producing a separable fastener wherein the scoops are completely hidden in viewing the assembled stringers from the surface thereof opposed to the surface of the stringers, to which the scoops are attached.
The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which the separate parts are designated by suitable reference characters in each of the views and, in which:
FIG. 1 is an enlarged plan view of one scoop as attached to an edge portion of a stringer of a separable fastener.
FIG. 2 is a section on the broken line 2 2 of FIG. 1 and diagrammatically indicated in dot-dash lines one side edge portion of a slider engaging a special heeled portion provided on the scoop.
FIG. 3 is a section on the line 3-3 of FIG. 1 of the showing of the scoop in FIG. 1 and portions of scoops of a companion stringer coupled with said first named scoop.
FIG. 4 is a sectional detail view, generally similar to the section of FIG. 2 on a reduced scale and diagrammatically illustrating the dies and associated parts for forming the scoops; and
FIG. 5 is an enlarged section on the line 55 of FIG. 4 showing part of the die structure and its engagement with the bead of the stringer tape.
In the pressure injection of metal or other materials into the cavity of a die in forming a cast article upon a tape or similar mounting having braid interstices or other crevices, I have found that the pressure of injecting the material into the die and onto the mounting results in extending the cast material into such interstices or crevices to establish a positive securing and attachment of the casting to the mounting. Further, in providing on the surface of the mounting to which the casting is attached a supplemental element such, for example, as a bead, the casting material will envelope the bead and, thus, establish a further means of securing the casting to said surface of the mounting.
In illustrating one adaptation and use of my invention, I have shown in FIGS. 1 to 3, inclusive, the attachment of scoops to one surface only of a stringer tape in producing separable fasteners which 1 term one-sided separable fasteners, in other words, wherein the scoops are disposed in their entirety upon one surface only of the stringers.
In FIGS. 1 to 2, it) represents a stringer tape, usually constructed of woven fabric, and at ll, 11' I have shown two beads extending longitudinally of the stringer tape 3,li5,6% Patented Dec. 31, 1963 "ice and parallel with respect to the edge 12 of the tape. The beads ll, ll can be integrally woven in the formation of the tape or can be stitched or otherwise attached, as known in this art. In either form of construction, recesses or undercuts 3.3 are formed at opposed sides of each of the beads, as shown at the right of FIG. 2. The modified showing at the left of FIG. 2, by virtue of the irregular ectioning, will be later described.
At 14 I have shown one of a number of scoops equally spaced along the stringer It the substantial central body portion lid of the scoop being arranged over and attached to the beads 11, ll. At 16 I have shown an extended heel portion having a lower bevelled surface 17 and an outer bevelled surface 18. The surface 17 is spaced sufficiently above the surface 1% of the tape id to receive the flanged side 2d of a slider 21, as indicated in dot-dash lines at the left side of FIG. 2, the slider being employed to couple the scoops of companion stringers together in an assemblage, as diagrammatically shown in FIG. 3, as with other types of sliders used on separable fasteners of the type and kind under consideration.
With the exception of the showing in FIG. 3, only a single scoop is shown in order to simplify the present illustration and in view of the fact that it is well known in the art that scoops of the kind under consideration are spaced along the stringer tapes in a manner to facilitate coupling engagement of the scoops of companion stringers.
Each scoop has a coupling end portion 22 comprising a head 23 having laterally projecting sides 24 and a fiat lower surface 25 spaced above the tape surface l9, as clearly illustrated in FIG. 2 of the drawing. This spacing prvoides clearance for reception of Wear shelves 26 laterally extending from sides of the inner female or recessed portions 2 7 of the coupling end 22, as will clearly appear in FIG. 3 of the drawing. In this figure, the projecting sides 24' of the heads 23' of scoops of a companion stringer are shown overlying the wear shelves 26. In this connection, the spacing between 26 and 24 is consistent with the enlarged showing of the scoops. However, sozne clearance is required for entrance of the projecting sides 24 into the recesses 27 in establishing the coupling enga' ement and, here, the rounded surfaces 26' on the wear shelves 26 f cilitate this coupling engagemerit.
The outer boundary walls of the coupling end portion 22 of the scoop l4- and corresponding end portions 22' of scoops M are, for the most part, bevelled, as clearly illustrated, and parts of these bevels are shown at 28 and 29 in FIG. 3, these bevels facilitating the transverse bending or folding of coupled stringers one with respect to the other.
To illustrate the method of forming the scoops on the stringer, as diagrammatically illustrated in FIGS. 4 and 5 of the drawing, dies 3%, 31 and 32 form the cavity portion 33 of the scoop. At 34 is shown the sprue or gate pas sage for introduction of the casting material into the cavity 33 and arranged in this passage between the dies 36 and 31 is a casting transfer pin 35, around which the sprue or gate 34- is formed, as seen at 36. This procedure is common in the art and is utilized for transfer of the formed casting or scoop 14 from the casting station to a trimming station, where the sprue or gate 37 is trimmed from the resulting casting, this operation being performed when the dies are in open position.
Considering FIG. 5 of the drawing, here I have shown at 38 one side wall of the die 39 to simply indicate that, where recesses or openings 39 are formed in this wall, as well as the opposed wall of said die, they are so formed as to place the bead 11 under compression so as to extend the material or" the head 11 into the portions 39' of the recess or opening 39, as clearly indicated at the left of FIG. 2 of the drawing, to prevent discharge of the casting material at these positions and, yet, permit the free separation of the die from the beads if, 11. This same structure is also employed on that part of the die 36? engaging the bead lift.
in contrast, the bead within the die cavity 33 will be completely enveloped by the cast material, as indicated at the right of FIG. 2 of the drawing, in establishing a further anchorage of the casting with the stringer tape ill. The tape it is diagrammatically illustrated in the several views and no attempt is made to show extension of the casting material into the interstices of a braided tape or into recesses or crevices of any type of mounting that may be provided. However, in FIG. 2 of the drawing, I have indicated by a dot-dash line if; what can be regarded as the anchorage portion of the casting within the tape or other mounting it this line being irregular to diagrammatically illustrate irregularities in the contour of this anchorage line. In order to clearly illustrate this anchorage, the normal fabric sectioning has been omitted from the drawing. It will also be understood that this anchorage of the plastic material will also extend into the beads 1f, ill, as indicated by the dot-dash line if? in FIG. 2 of the drawing. The clot-dash line is illustrated in FIG. 3 of the drawing, but is omitted from FIG. 4.
It will appear from a consideration of FIG. 1 of the drawing that the die 32 which fits between the tape iii and the heel forming portion 36 of the die 39 forms the undercut in the heel portion. The die 32 is preferably moved to the left to a slight degree in separation of the dies 3% and .31. At this time, it is also well to point out that the bevelled or rounded surfaces bordering the entire scoop also facilitate free separation of the dies from the formed scoop. It will further appear that the large surface area of the scoop disposed upon the tape establishes an extremely secure attachment of the scoop to said surface of the tape. This surface engagement is increased by virtue of the wear shelves 26.
