Patented June 6, 1939 UNITED STATES SLmER Walter A. Behrens, New York, N. Y., assignor to -Ideal Fastener Corporation, Brooklyn, N. Y., a

corporation of New York Application December 16, 1937, Serial No. 180,220 3 Claims. (01. 24-205) This invention relates to improvements in sliders, for slide fastener assemblies incorporating fastener elements or scoops mounted in offset relation with respect to the tapes.

Broadly, it is an object of this invention to provide a slider of such construction as to provide for the accommodation at the lead entrance thereof of fastener elements mounted angularly with respect to the tape and to progressively guide 10 and direct the fastener elements flexibly mounted on the tape to the normal plane of the tape, at which" time the series of fastener elements on opposing tapes being directed in a common plane, may be interlocked by and within the slider.

15 Specifically, it is an object of this invention to provide a slider having spaced opposing wings united at one end to form a channel formation, having diverging arms, which are in a central transverse plane angular to that of the body of the channel and to each other, the contour of the leading end of the diverging arms being such as to accommodate the scoops in their normal angular position on the tapes, the diverging arms as they lead towards the body of the channel being of gradually decreasing angularity with respect to the plane of the latter, whereby upon reciprocation of the slider the scoops are respectively progressively displaced from angular to horizontal position for interlocking and from horizontal in- ?o terlocking position to their normal angular position on the tapes upon separation.

These and other advantages, capabilities and features of the invention will appear from the subjoined detailed description of one specific em- :3 bodiment thereof illustrated in the accompanying drawing, in which Figure 1 is a perspective view of a slide fastener assembly incorporating the slider forming the subject matter of this invention.

40 Figure 2 is a front elevation partially in section taken along lines-2--2 of Figure 1,

Figure 3 is a front elevation partially in section taken along lines 3-3 of Figure 1.

Figure 4 is a perspective view showing-the con- 45 struction of the slider.

Figure 5 is a perspective view of the "leading section-of the slider.

Figure 6 is a front elevation in section taken along lines 6--6 of Figure 4. 50 Figure '7 is a front elevation in section taken along lines 1-'l of Figure 4.

Referring to the reference characters in the drawing, numeral l0 represents a slider operating by reciprocation to interlock and separate co- 55 operating flexible stringers Ila and llb. As

shown in Figures 1 to 3 inclusive, the stringers Ho and llb each comprise flexible tapes I21; and lZb, the central transverse plane of which for the purpose of this illustrative embodiment. of the invention is horizontal, and upon the flexible 5 beads l3a and 13b of which there are mounted the unsymmetrical type scoops Ma and Nb, which by their nature and formation are angularly disposed and have their central transverse plane angularly disposed with respect to the horizontal l0 central transverse plane of the tapes.

As indicated generally in Figure l, and specifically in Figures 2 and 3, the tapes i211 and I2!) of the stringers II are at all times in the horizontal plane, while the scoops I3o and I3b at the left of 15 Figure l, and in Figure 2, are shown as angularly disposed with respect to the central transverse plane .of the tapes, prior to interlocking thereof, while, as shown at the right of Figure 1 and in Figure 3, the scoops as interlocked are disposed so 2 that their central transverse plane is parallel to that of the tapes, which latter condition is necessary in order to bring about proper interlocking of the stringers Ila and Nb.

To bring about the necessary transposition of the scoops on the stringers l I from the normal to the interlocking condition, there is applied the slider formation, the construction of which is shown in detail in Figures 4: to 7 inclusive.

The slider [0 comprises of a structure having an opposing wings I6 and I1 forming top and bottom elements connected at one end by a separator post [8 and having a substantially V-notched wall formation We and H31) to define diverging channels 19a, and Nb, merging into a single channel 35 20, there being mounted'adjacent the separator post a handle 2|, extending above wing it, and upon which handle there is carried tab 22 (see Figure 1) for permitting reciprocation of the slider ID to interlock and separate the stringers. 40,

The lower wing H has a side wall formation 23 to substantially accommodate the vertical dimensions of the scoops Ma and Nb, while wing It is flat through a greater portion of its length and of slightly less width than wing I1.

As shown in perspective view of Figure 4, indicating the leading end of the slider, the opposing portions A and B of the wings l6 and H are shaped to provide angular diverging channel formations I9a. and Nb corresponding to and symmetrical with the normal angular positioning of the scoops I24: and l2b, as mounted on the tapes and shown in Figure 2. These channel formations, as they progress towards the merging point in advance of the apex of the V-notch of the separator post, gradually decrease'in angularity, as shown in their relation to the opposing portions C and D, which are at the merging point (see Figure 6), eventually attaining a horizontal plane of the opposing portions E and F, as shown in Figure '7, which last named view indicates the section of the single channel 20.

As can be observed from the detail shown in Figures 4 to 7, the opposing portions A, C and E on the upper wing, and B, D and F on the lower wing are shaped to define respectively cooperating sections, the central transverse plane of which gradually decreases from that of an extreme angle with respect to a horizontal central transverse plane to that of parallelism to such plane, and in which horizontal transverse central plane interlocking of the stringer is desired and carried out.

In Figure 1, there has been graphically shown the displacement imparted to the scoops carried on the stringers in their passage towards interlocking or separation, and the three views, 5 to 7 inclusive, graphically indicate the contours of the channel formation which the scoops encounter as the slider in its reciprocation acts upon said scoops to permit passage thereof through the slider; the gradual displacement of the scoops from their normal transverse central plane angular to that of the tapes and the reverse thereof being capable of accomplishment due to the flexible mounting of the spaced scoops on the flexible tape and flexible bead carrying the same.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims.

I.claim: 1

1. In combination with flexible interlocking stringers, incorporating scoops normally mounted in a central transverse plane angular to that of the tapes carrying the same, a slider comprising a body portion having diverging channeled arms merging into a channeled stem through which the scoops of the stringer series pass for interlocking and separation upon reciprocation of said slider, the diverging arms and stem having different transverse central planes, the stem having a central transverse plane parallel to that of the tapes and the diverging arms having a central transverse plane of decreasing angularity with respect to that of the stem as the diverging arms lead to the stem, the leading end of the diverging arms having the same central transverse plane as that of the opposing scoops on the stringer series in their normal mounting.

2. In combination with flexible interlocking stringers, incorporating scoops normally angularly mounted with respect to the central transverse plane of the tapes carrying the same, a slider comprising spaced wings interconnected at the leading end to form diverging channels merging into-a single channel, the single channel having its central transverse plane parallel to that of the tapes, and the diverging channels having central transverse planes angular with respect to each other and to that of the single channel, the leading end of the diverging channels having'the same central transverse plane as that of the scoops in their normal mounting on the tapes, the diverging channels along their length leading to the single channel having a central transverse plane of decreasing angularity with respect to the single channel, whereby upon movement of the slider, the scoops of the respective stringer series entering the diverging channels are displaced from their normal angular mounting with respect to the tapes to a position where their central transverse plane is parallel to that of the tapes and the single channel, as they progress towards and enter into the single channel for interlocking.

3. In combination with flexible interlocking stringers incorporating scoops normally mounted in a central transverse plane angular to that of the tapes carrying the same, a slider comprising opposing wings connected by a separating post to define diverging guideways merging into a single guideway for interlocking and separating the scoops of the stringers upon reciprocation of said slider, the leading end of the diverging guideways defined by the wings having the same central transverse plane as that of the normal mounting of the scoops 0n the stringers, the central plane of the remaining portions of the diverging guideways being of gradually decreasing angularity with respect to that of the merging guideway, the portions of the wings defining the merging guide- Wa'y having a central transverse plane parallel to that of the tapes, whereby the normally angularly disposed scoops on the stringers, upon passage through the diverging guideways, are gradually displaced from angular central transverse planes of mounting with respect to that of the tapes and the merging guideway to parallel central transverseplane of interlocking with respect to that of the merging guideway and tapes.
