. 1 This invention relates to an eye-stay assembly fforming part Q f a fastening device of the type 'which Ais commonly used on 'mens clothing.

It has vbeen the practice with the higher-priced mens clothing touse with the trousers a hook .and eye at `the y to secure the two parts thereof at the top. With tailored suits vit has been customary touse a special type .of hook and eye, both .sewed tothe .trousers adjacent the waist band.

`With increasing labork costs .this is now proving to be ,an `expensive expedient. Nevertheless this Y.type v'of lfastening isgreatly preferred to buttons,

particularly 'for the higher-priced mens clothing. One shortcoming of the hook and eye .type .of

`fastening is that each of these parts is commonly f-anchored in position 'by threads which are sewn :through the fabric. With continued use or eX- treme strain the threads will break, .thereby-permitting the fastening to become loose. This is a :shortcoming Vwhich is also obviated by the present construction.

Primarily my 'invention here is concerned with the eye-stay assembly.' It is complementary to .aihook which, as shown, :includes a tongue conf- :nected Ythrough a reversebend with a base that is secured to the `fabric by any approved means.

In the present eye-.stay assembly the eye component embodies Vstop shoulders beyond which are prongs for penetrating the fabric and which -lie atwise' thereon when turned and clinched; :the stay component cooperates with such an eye :by affording v,a `base in opposition to the stop shoulders, and so placed that the .fabric is dis- ;posed vbetween the eye and stay, the prongs of the'eye when clinched, serving to secure the stay Xedly in place and to be protected thereby. A suggestive embodiment of my invention is yillustrated in the accompanying drawing, wherein:

Figure 1 is a perspective view showing a typical Fig. -6 is a view in section, taken 4on line vl--S` of Fig. 4; and

Fig. 7 which is a view similar to Fig. 3 shows anveye and stay platelof somewhat diferent form. 1'

8Claims. (Cl. Zei- 227) A typical installation of the presentV fastening is in connection with a pair of trousers the upper portion of which is illustrated in Fig. 1. -The front fly` consists of two aps a and b to the latter of which is affixed a hookrcomponent H at or near the waistband. The complementary component which is carried by the ny nap a includes an eye E assembled with a stay S .both embodying certain features whichare special to this invention. In a fastening of this general character the hook Vis adapted to engageor disengage the eye `whereby to secure the y in closed condition .or release it for openingmovement.

The hook 'here shown is desirably produced from sheet metal which is stamped and bent to provide an arcuate tongue `lill that is reversely 'bent to connect witha base plate l2 wherein may fbe formed Acertain slotsto define bars i3 adjacent thereto. In usual practice, the hook will be carried upon the inner face .of the flap b, whereit is xedly secured in place as by stitching lli which connects the bars I3 to the fabric. A suitable facing I5 may be aixed to the waistband, as shown.

In the present fastener the eye Ei may also be produced from sheet metal which is stamped and `bent to provide a relatively at bar I6 having opposite parallel endl portions with inset stop shoulders l1 beyond which is formed a pair of prongs I8 which initially are arranged in parallelism. These prongs are adapted to penetrate the fabric in the fly flap a, passing inwardly therethrough from the outer face thereof. These prongs are adapted also to pass between or through .guides I9 near the ends of `an elongated plate constituting the stay S which lies upon the inner face ofthe flap a. 'These guides in the form shown take the form` of slots closed on all four sides, as indicated clearly'in Fig. 2. When the `prongs have been inserted through theguide slots of the stay, the projecte ing end portions of the prongs may then be bent linwardly toward each other and into the space provided byY a pair of medial slots 2| which are properly located for this purpose between the two Aend guides I9 of the stay S. Between each guide I9 and the proximate slot 2| the plate body is inset at c toward the eye for a slight distance, vperhaps half the thickness of the fabric ply which they penetrate (see Fig. 5), whereby to accommodate, in lpart at least, the prongs -IB at the point where they are extended thereacross along the inner face `of the fly ap c. The protrusion of the prongs at `these two points is materially reduced A'in consequence.

i The two prongs when so disposed within the medial slots are oiset relative to each other so as to be accommodated within the confines of the relatively narrow stay plate S. This may be accomplished readily by forming on one prong an elongated bevel :1: which faces a corresponding elongated bevel 'y formed on the other prong, as best shown in Fig. 3, or by elongately tapering the prongs along opposite edges (see Fig. '7) for reception in a single elongated medial slot 22. This disposition of the two prongs completely eliminates protrusion of their sharp ends by providing therefor a confining housing into which they are bent (see Fig. 5). The tapered medial slots 2| conform to the configuration of the prongs I8 and each is defined by a transverse wall, a longitudinal wall and an inclined wall connecting the longitudinal walls, and the inclined walls of the slots I8 are arranged in parallelism, as clearly illustrated in Figs. 2 and 3 of the drawings. This provides for maximum length of the prongs and maximum strength of the stay between the tapered slots 2| which accommodate the tapered prongs I8. Positioning holes 23 are shown near opposite ends of the stay plate to facilitate its placement in the correct location when the assembly operation is performed by a machine.

When the eye E! and stay S are assembled, the fabric flap a will be firmly clamped therebetween. This makes for a very strong fastening which will not become loose or tear the fabric under conditions of strain. It is important that the exposed bar I6 of the eye remain spaced from the outer face of the ap a distance sufficient to permit the tongue l0 of the hook H to enter therebetween. This spacing is assured by the stop shoulders Il at opposite ends of the eye bar which engage with the fabric.

The eye-stay assembly of my invention is desirably made of metallic flat stock. This has certain advantages. An enhanced strength may be obtained for the eye without increasing the distance of its protrusion from the face of the fabric to which it is secured. Furthermore it is reinforced so as to resist bending when subjected to strain tending to pull the eye to one side. Under such conditions the eye connection with the stay which is fixed will involve a motion on the part of the stay corresponding with that which is executed by the eye, and this adds appreciably to the resistance. While the fabric may bend to some extent, the broad base of the stay tends to oppose any undue bending movement on the part of the fabric, thus stabilizing the entire eye-stay assembly and enhancing its strength to withstand the various conditions encountered in service.

I claim:

l. For fastening a fabric ny to one flap of which is aiixed a hook, an eye-stay assembly carried by the other fly flap, the eye being elongated with parallel prongs extending transversely from its opposite ends and stop shoulders at the juncture of the prongs with the eye, the prongs being adapted for insertion through the flap fabric to the extent permitted by engagement of the shoulders with one side thereof at which point the major length of the prongs is disposed to the opposite side of the fabric, and the eye between the two sets of stop shoulders being extended to lie spaced from the fabric a distance suiiicient to accommodate the coacting hook on the fly flap first named, and a base plate opposite the eye disposed on the fabric side reached by the prongs consisting of an elongated stay formed medially with a slot and therebeyond, near each end, with means to guide one prong in its extension from one face of the stay to the opposite face thereof, the two prongs being bendable inwardly toward each other to lieflatwisev in'a single plane -within the confines of the slot medially of the stay.
