5 Claims.

fastener assembly, incorporating a continuous bead, to provide in said slidera wing formation serving as an enclosing socket for said bead in conjunction with another wing of said slider serving as a channeled guideway for the spaced fastener elements carried on the stringers.

Further, it is an object of this invention to provide in a coveredslide fastener assembly incorporating a continuous beaded tape, for a slider, one of the wings of which is in the nature of a plurality of U-shaped channels acting on, a substantial surface of the interlocking fastener elements applied in the assembly and having for its other wing a plurality of opposing channels to form sockets substantially enclosing the cover beads forming part of the assembly.

Specifically, it is an object of this invention to provide in a slide fastener assembly, wherein the stringer incorporating fastener elements has at its edge a bead for covering the head of the fasteners forming a covered slide fastener assembly, to provide a slider, one of the wings of which is in the nature of a channel substantially enclosing the bodies of the spaced fastener elements and the other wing of which incorporates a pluralityv of spaced sockets serving to enclose and guidethe beads of the stringer serving as the cover portions for the heads of the fastener elements, such construction serving to provide through the guiding action of the channels on the slider upon the continuous tape bead, for a medium whereby the fastener elements suspended on the tapes are positivelydirected into the channels of the slider cooperating therewith.

These and other advantages, capabilities and features of the invention will appear from the subjoined detailed description of one specific embodiment thereof illustrated in the accompanying drawing, in which Figure 1 is a perspective view of a slide fastener assembly incorporating my slider.

Figure 2 is a perspective view of a preferred embodiment of my slider. I

Figure 3 is a perspective view of the tab lug forming part of the slider.

Figure 4 is a perspective form of the slider.

Figurefi is a perspective view of the tab lug forming partof the slider shown in Figure 4.

view of a modified Referring to the reference characters in the drawing, numeral Ill represents a slider acting upon stringers of the character shown and described in Letters Patent to David Silberman, 2,097 ,475, dated November 2, 1937, each comprising of a flexible tape l I having a body portion l2 extending in a horizontal plane, a bead formation I3 at one of its edges, and a bead formation [4 intermediate of its edges. The intermediate bead formation. l4 carries depending therefrom spaced fastener elements l5, whose jaws l6 and I6 substantially surround and grip the same. The end bead formation I3 is disposed over-and rests against the top face ll of the head l8 of the fastener element, which fastener element incorporates the usual male and female locking or meshing portions l9 and I9.

Referring in particular to the slider I 0, the formation and cooperation of which, with the stringers and particularly the cover bead l3 at the edges of such stringers, forms the essence of this invention; such slider is formed of a channel shaped metallic stamping Y-shaped in conformation As indicated in the two modifications thereof shown herein, the lower wing section comprising diverging arms 20 and 20' which lead to a merging stem or arm 2|, the cross-section of the same being substantially in the nature of a. U-.-shaped channel and serving respectively at the diverging arms and the merging stem to surround the sides and lower portion of the respective fastener elements as separated and then interlocked. f

As shown in Figures 1, 2 and 3, the slider is formed to provide an angularw-edge 22 between and defining the diverging channels 20 and 20', said wedge being integral with and forming'the inner side wall of the respective diverging channels. Integral with and extending in arcuate'formation for the length of .the wedge there is provided 'on'upper wing section, arcuate arms or socket formations 23 and 23' adapted to enclose and act upon cover beads l3 at the edges of the tapes. A separable tab lug 24 comprising a longitudinally slotted body portion 25 having depending therefrom integral leg 26, is mounted between the walls defining the wedge 22 by welding or other fastening method, so that theslider may be actuated for reciprocation'to separate interlocking fastener members by pulling the tab lug or the ring tab 21 carried on thehoriz ontal slot thereof.

As shown in Figures 4 and 5, the slider-is of length with the channeled walls thereof serving to enclose the bottom and sides of the fastener elements; there being mounted as by welding or riveting or the like, a tab lub 24 having disposed on opposite sides of its leg 26 wings 23 and 23' for surrounding and acting on the edge beads l3 as the slider is reciprocated.

In operation, the slider as it reciprocates functions as follows: The walls defining the diverging channels 20 and 20' leading to the merging channel 2| of the lower wing surround the side walls and bottom of the fastener elements and act thereupon, While the arcuate arms or socket formations 23 and 23' of the upper wing carried on the wedge in the embodiment shown in Figures 1 to 3 and upon the tab lug in the modification shown in Figures 4 and 5, enclose the beaded edges l3 of the tapes and act as sockets and guides therefor.

The enclosing and guiding function of the arcuate arms or

socket formations

23 and 23 acting upon the edge beads l3 provides the advantage that the passage of the spaced fastener elements through the slider as the latter is reciprocated, is controlled by the continuous beads l3 enclosed within the arcuate arms or socket formations, the fastener elements being supported and maintained 'in proper alignment for entrance particularly, and thereafter passage through the slider.

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. In a slide fastener assembly, in combination, opposing stringers, each provided with a series of spaced fastener elements and a continuous bead extending longitudinally thereof, and a slider cooperating with saidstringers, said slider beingprovided with a plurality of channeled formations to accommodate the fastener elements of the stringers, and being provided with socket formations closely following the contour of the beads of the stringers for accommodating the beads, said slider upon reciprocation serving to interlock and separate the fastener elements, and the beads upon passing through the sockets of the slider serving as a guide for the fastener elements entering the channeled formation.

2. In a slide fastener assembly, in combination, opposing stringers, each provided with a series of spaced fastener elements and a continuous bead:

extending longitudinally thereof, and a slider cooperating with said stringers, said slider having opposing wings, one of which wings is provided with channeled formations to accommodate the fastener elements of the stringers, and the other of which wings is provided with socket formations closely following the contour of the beads of the stringers for accommodating the beads, the slider upon reciprocation serving to interlock and separate the fastener elements and the beads upon passing through the socket formations, serving as a guide for the fastener elements entering into the channeled formations.

3. In a slide fastener assembly, in combination, opposing stringers, each provided with a series of spaced fastener elements and a continuous bead extending longitudinally thereof adjacent the fastener elements, and a slider cooperating with said stringers, said slider having opposing wings, one of which wings is provided with channeled formations to accommodate the fastener elements of the stringers, and the other of which wings is provided with socket formations closely following the contour of the beads of the stringers for accommodating the beads.

4.
