Patented Nov. 2, 1937 UNITED STATES PATENT OFFICE David Silberman, New York, N. Y., assignor to Ideal Fastener Corporation, New York, N. Y., a corporation of New York Application July 24, 1936, Serial No. 92,359

8 Claims.

This invention relates to improvements in slide fasteners, and methods of producing the same, being particularly directed to a covered slide fastener assembly incorporating beaded cover members.

Broadly, it is an object of this invention to provide a novel assembly of opposing series of slide fastener elements mounted on tapes, said slide fastener elements being normally mounted at an angle with respect to the plane of the tapes,

and being adapted, upon closure of the slide fastener assembly, to be disposed in the same plane or a plane parallel to that of the tape, the tape having a bead at one edge thereof serving to cover the normally exposed heads of the respective fastener elements when the assembly is in closed position.

Specifically, it is an object of this invention to provide a covered slide fastener assembly in :0 corporating a plurality of beads, one at the edge and the other intermediate the edges of the tape,

the intermediate bead being clamped in the jaw of the fastener element and the edge bead serving to overlie the exposed surface of the head '3 of the fastener elements.

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 30 drawing, in which Figure 1 is a perspective view of the covered slide fastener forming the subject matter of this invention.

Figure 2 is a perspective view of one embodi- 5 ment of the tape.

Figure 3 is a perspective view of another embodiment of the tape.

Figure 4 is a perspective view looking downward on the tape embodiment shown in Figure 3.

Figure 5 is a front elevation in section taken along lines 5--5 of Figure 1.

Figure 6 is a front elevation in section taken along lines 6-6 of Figure 1.

Referring to the reference characters in the drawing, numeral It represents a slider having the usual channel formations I l defined adjacent the wedge [2 for acting'on the interlocking fastener elements l3 of the opposing series carried 50 on tapes l4.

As shown in Figure 2, indicating a preferred embodiment of the tape l4 prior to the attachment of the fastener elements, the same comprises a flexible fabric having a body portion I5 55 extending in horizontal plane, and having a bead posite faces of the body portion I5.

formation l6 at one of its edges and secondly, a bead formation I'l intermediate of its edges, the end bead formation generally being of greater diameter than the intermediate bead formation. As shown in Figure 2, the bead formations are formed by weaving material about a cord [8 and are disposed on opposite faces of the body portion l5.

As shown in Figures 3 and 4, tape M has the v bead 6 at its edge, but instead of having an intermediate woven bead formation, such bead formation comprises acord l'l' sewed on as at I 9 along its length to the surface of the tape, the respective bead formations being disposed on op- In assembling the slide fastener elements of the series 13 onto the tape, the clamping jaws thereof are adapted to grip bead l6, causing the bead to be displaced inwardly with respect to its original position relative to the body of tape i5 shown in Figure 2, resulting in bead I! being displaced to become the remoteor edge bead of the tape, the said bead l'l serving to overlie head 2| of the fastener l3.

As shown in Figure 5, the fastener members l3 as mounted on tapes shown in Figure 6, are caused to be displaced from a position in Figure 6 to that of a horizontal plane after passage thereof and the tape portions associated therewith 0 through the channels ll of the slider III, with the result that bead ll of the respective tapes overlying the heads of the fastener l3, are caused to abut one another when the fastener heads 2| interlock at the

respective mating sections

22 and 23, thus covering the slide fastener assembly as shown in the upper part of Figure 1.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of 40 the invention as set forth in the appended claims.
