This invention relates to separable fasteners employing stringers having scoops to couple and More particularly, the inacting scoops so constructed as to provide universal coupling of the stringers; Still more particularly, the invention deals. with scoops wherein pairs of male and female couplings are arranged on each surface of the scoop, and the coupling portions of one surface being opposed to the coupling portions'of the other surface. The novel features of the invention will be best understood from the following descriptions 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 a perspective view showing one scoop on the beaded edge of a fastener stringer.

Fig. 10 is a reduced side view of the scoo shown in Fig. 9; and
Figs. 11 and 12 are sections substantially on the lines li-ll and 12-12 of Fig. 10.
My present invention deals with scoops of separable fastener stringers of what I term the coreless type. By this is meant, the scoops are formed from die castings without the use of core pins or the like on the parting line of the dies, thus adapting scoops of this type and kind for casting in multiple directly upon the stringer tape. In other words, the scoops are of such form as to readily free themselves from the die cavities in the separation of the dies, and at the same time, the scoops are so formed as to provide male and female couplings retaining the scoops of coupled stringers against transverse and lateral separation.
on the other hand, the scoops are also of what I term the double action type. That is to say, both side portions of the scoops are substantially snow- 12 Claims. (Cl. 24-20513) the same, thus sliders are adaptable for movement along the stringers with the narrow end of the sliders arranged in either of two directions on the stringers in coupling and uncoupling the scoops.
Notwithstanding the fact thatthe male and female couplings have a staggered arrangement on' each surface of the scoop, the arrangement on opposed surfaces is such that stringers may be united in a universal manner, that is to say, with the ends of the stringers arranged in any position one with respect to the other. This latter construction materially simplifies installation of the stringers in the supports therefor by manufacturers, and avoids any possibility of improper mating arrangement of stringers in the supports. At the same time,'production of the stringers is simplified in that a single stringer is produced. In other words, no lefts and rights are required.
In Figs. 1 to 4 inclusive'is shown one form of scoop construction, the scoop being generally identified by the reference character l5. In Figs. 1 and 2, l6 represents part of a stringer tape, and I! the beaded edge thereof. The scoop l5 comprises a mounting end portion l8 arranged upon the beaded edge l1 and a coupling end portion is which projects outwardly from said beaded edge.
The coupling end portion of the scoop l5 has an outer coupling end or head 20 which is substantially of diamond shape cross sectional form. The head 20 forms the male coupling of the scoop which is adapted to enter the channeled or recessed portion of adjacent scoops in coupling stringers together, the channel or recess being indicated by the reference character 2! in Figs. 1 and 2 of the drawing, and this recess is arranged on both surfaces of the scoop, and each recess is substantially V-shaped in cross sectional form, as will clearly appear from a consideration of Fig. 1.
The walls of the head 20 and recesses 2l taper in the direction of the side surfaces of the scoop in order to provide clearances between adjacent coupled scoops for bending and flexure of the stringers. These tapers are indicated in Fig. 1 of the drawing and are more clearly illustrated by the reduced lines of the head 20, as seen at 22 in Fig. 2 and the reduced lines 23 at the inner portions of the recesses 2|. In other words, the scoops are of greatest thickness along the longitudinal center lines represented at 24 in Fig'. 1 of the drawing, and this also appears from the cross sections through the scoop shown in Figs. 3 and 4.
The center line 24 divides the scoop into coupling side portions 25 and 26, note Figs. 1 and 3.
shown in Fig. 3 of the drawing.
In Fig. 4 of the drawing is shown a section through the recessed portion. of the scoop. At this portion, the coupling side 26 is :of greater height than the coupling side to form a coupling shoulder 29 on the upper surface of the scoop, whereas the coupling side 25 extends downwardly a greater distance than the coupling side 26 to form a coupling shoulder with the lower surface of the scoop.
As will clearly appear'in Fig. 2 of the drawing, H
the bevelled surfaces forming one side of the head 20 and one side of the recesses 2| register in a single ridge 3| at upper and lower surfaces of the scoop and extending substantially from the peaks of the head to the base of the recesses. In other words, the shoulders 21 and 28 terminate substantially at the high-points of the diamond head 20, whereas the shoulders 29 and 39 terminate at the base of the recesses or channels 2|.
When scoops of opposed stringers are coupled together, it will be apparent that the shoulder 21 of one scoop will engage the shoulder 30 of an adjacent scoop, and the shoulder 28 of said scoop will engage the shoulder 29 of still another scoop in coupling the scoops against transverse separation. From this standpoint, it may be said that the outer end portions of the heads 20 have interengaging male coupling shoulders 21 and 28, whereas the inner end portion of the recesses or channels 2| have male coupling shoulders 29 and 30, and that the intervening portion of the scoops, in other words, the outer ends of the recesses or channels and the inner ends of the head have flat abutting and uncoupled surfaces, except to the extent that the shoulders extend onto said surfaces.
It will also appear that opposite side surfaces of the scoop body |5 have recesses 32 in alinement with the base of the recesses or channels 2|, and these are provided to facilitate greater tilting or swinging movement of the scoops one upon the other in the flexure or bending thereof.
In Figs. 5 to 8 inclusive is shown a modified form of scoop 33, and as this scoop is generally of the same contour as the one already described (the head 34 corresponding to the head 29and the channels or recesses 35 corresponding to the channels or recesses 2|) no further specific description with regard to this structure of the scoop will be given, as it simply would be a repetition.
The structure of Figs. 5 to 8 inclusive differs from the structure in Figs. 1 to 4 inclusive, in providing on the center high-point line 36 of the scoops limited coupling shoulders 31 and 38 at the upper and lower peaks of the head 34 and other limited coupling shoulders 39 and 4|] at the base of the channels'or recesses 35. In other words, the shoulders 31 and 38 are similar to the shoulders 21 and 28, and the shoulders 39 and 40 are similar to the shoulders 29 and 30, except that they are located centrally of the heads and recesses rather than being disposed on one wall only of the heads and recesses.
Omitting for the sake of consideration the part of the shoulders 39 and 49, which extend onto the walls of the head 34 and recesses 35, it may be said that the shoulders occupy only part of the outer portions of the head and only partof the inner portions of the recesses, and these parts would form a limited coupling engagement between adjacent scoops. However, as shown in the accompanying drawings, the shoulders extend onto the head and from this standpoint would constitute a further modification in adding the interengaging couplings on the head where they are substantially entirely lacking on the ridges 3|.
Considering the cross sectional view in Fig. 7
of the drawing, it will appear that the shoulders 31 and 38 are formed by what may be termed notches or recesses 42 and 43 in the head 34. In considering Fig. 8 of the drawing, it will appear that the shoulders 39 and 40 are formed by what may be termed enlargements or projections 44 and 45 in the recesses 35. Inconnection with the cross sectional views shown in Figs. 3, 4, 7, 8, as well as 11 and 12, it will be apparent that for the purpose of simplifying the illustrations these views simply show the part of the scoop where the section'line is indicated in the associated figures, omitting the background.
In Figs. 9 to 12 inclusive is shown another modified form of scoop 46. Here again the general scoop structure is much the same as 'that shown in Figs. 1 to 4 inclusive as well as in Figs. 5 to 8 inclusive, and again no further detailed description with regard to the scoop structure will be given. The scoop 46 has shouldered couplings 41-48 and 49-50, quite similar to the shoulders 31 and 38, formed in the head 5| of the scoop, whereas the shoulders 49 and-50 are formed in the channel or recesses 52. primary difference between the two structures shown in Figs. 5 to 8 and 9 to 12 is in the fact that the shoulders 41 and 48 are formed by channels 53 and 54, which are more or less conical in form or U-shaped in cross sectional form adapted to receive core like projections 55 and 56. So formed, these channels and projections in and of themselves provide for interlocking the scoops against lateral or pull-apart separation, in addition to the interlocking against transverse separation afiorded by the shoulders or faces 41-50.
Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:
