RPORATION OF INDIANA V FASTENING FOR WEARING APPAREL AND THE LIKE Original No. 1,610,839, dated December 14, 1926, Serial No. 50,508, filed August 15, 1925, and in. Germany November 25, 1924. Application for reissue filed February 26, 1927. Serial 1T0. 171,755.

This invention relates to a fastening for wearing apparel and the like and ofthe kind in which staggered rowsof fastening members are connected to the edges to be joined 5 and drawn into interlocking positipn by means of a slide.

In known fastenings of this kind, the inter; locking elements are either spherical or elongated. The spherical elements have the advantage that they can be drawn together with little friction and from any direction, but, as they allow a' pivotal relative adjustment of the members and as the slide requires them to be in parallel planes when the fastening is opened, a rectification of the position must take place which often renders the opening process very troublesome. The elongated interlocking elements retain the members in their correct position relative to the slide, but they must be drawn together either in longitudinal or transverse direction. This requires in both instances a bending of the edges to which considerable resistance is offered when said edges, as in the case of tents for instance, are in tension.

The principal objects of my invention ar to provide simple and effective means for preventing relative pivotal displacement of the interlocked fastener *members; to divide the projections and recesses or to separate portions thereof so as to provide an interengagement for opposing such displacement; and to provide spherical interlocking elements with ribs and grooves or other suitable matching indentations and projections for this purpose. My invention also seeks to produce a fastening whose members can be brought together from any direction and which at the same time are prevented, when in engagement, from pivotal relative displacement, and includes a slide adapted to draw together and separate the fastenermembers by a combined relative endwise and sidewise movement of the members or a movement in a direction which lies between the longitudinal and the transverse direction of the members. By this arrangement the bending of the edges is reduced to a minimum, and the fastening members can be drawn toshowing the slide in operation.

F 1g. 2 is a sectional view of the fastening 'on an enlarged scale, and

Fig. 3 is a plan of the recessed side of one of the fastening members. Fig. 4 is a sectional view modified construction, and

I Fig. 5 is a plan of the recessed side of one pf the fastening ,members of this construc- 1on.

Fig. 6 is a horizontal sectional view of the interlocked fastener of Fig. 1.

Fig. 7 shows the manner in which the fastening members are drawn together, and

Fig. 8 shows the same thing in connection with the slide.

The edges 6 of sheets of fabric, leather or the like are connected in known manner by means of staggered rows of interlocking fastening members a which are drawn togetherby means of a slide 0. The fastening members interlock by means of heads formed so as to present a spherical projection e and at the other side a spherical cavity 03, the projecof a fastening of tion of one member being adapted to engage relative pivotal displacement about the center of the spherical surfaces. By making the projection e and cavity a of spherical form a portion of the element (1 adjacent the outer end has a transversely arched form and the groove 9 and rib f divide this transversely arched portion substantially midway between the lateral edges of the element. The groove 9 which extends len thwise of the element is preferably of so stantially. V-

accomplished in the illustrated shaped form in cross" section with oppositely inclined side faces so that the ribs 7 will readily enter and seat therein and this groove in the interlocking operation serves to guide the opposed element over the projection to the interlocked position.

It is preferred to groove the projection as this avoids the increased elevation that would be occasioned by using a rib on the projection in place of the groove g, and moreover, by the grooving of the projection, the latter is divided or separated into two portions or substantially a pair of projections which engage in the corresponding pair of depressions which are formed by the rib f in the depression d and this sort of two point interengagement of the interengaged members effectively prevents relative pivotal displacement thereof. Auxiliary depressions and projections of other form than the ribs 7 and grooves 9 may also be used as it will be readily apparent to accomplish the keying .of the interlocked members against relative pivotal displacement. The fastening members will thus be retained in their correct position relativeto the slide 0.

The spherical surfaces may be incomplete or substantially hemispherical as shown-in Figs. 1, 2 and 3 or they may be extended so as to form the head into a complete sphere or substantially ball shaped end portion only interrupted by the cavity d as in Figs. 4 and 5. The spherical depression d and projection e afford a substantially circular interlocking portion which is lune shaped in section lengthwise of the element and the larger are or surface of the projection has a sliding joint bearing in the smaller arc or recess of the next adjacent member. The groove 9 provides an auxiliary seat which is diametrically arranged with respect to this said circular interlocking portion and the rib f on the other side is correspondingly arranged. The heads are shaped so as to maintain, between the bodies of adjacent members, a free space which is substantially equal to the head diameter, as shown in Fig. 4.

To obviate excessive bending of the edges 6, the fastening members are brought together in an oblique direction, that is, by a combined relative endwise and sidewise movement and at an angle lying between the longitudinal and the transverse direction of the members. For this purpose the guide channels in the slide 0 are carried from a coinciding position in which they lie in the same plane at the narrow end \of the slide towards diagonally opposite corners at the wide end and swing respectively at opposite sides of said plane, so that the fastening members will approach each other along a straight line from the position shown by full lines in Fig. 8 to the position shown by dotted lines.

I claim: i

A fastening for wearing apparel and the like comprising staggered rows of fastening members connected to the edges to' be joined and adapted to mesh and interlock, each member being formed with interlocking means in the form of a spherical head and with a semispherical recess in said head, the heads being formed with intermeshing' ribs and grooves which break the continuity of the spherical surfaces of said head and recess so as to prevent pivotal relative displacement of the members, and a slide for guiding the members successively into and out of engagement with each other.
